    • Abstract
  • Background 

    Galliformes are widely distributed throughout the world and economically important to humans as domesticated animals or gamebirds. They are at a unique position for advancing knowledge and techniques of wildlife conservation as the barometer of the status of applied ecology. Populations of many galliform species have declined mainly due to habitat loss and over-hunting. An assessment of knowledge of Galliformes could help to provide guidelines for future research and conservation strategies.

    Methods 

    Using the Web of Science search engine, we conducted a literature review of galliform-related articles published from 1990 to 2016. We used the "research area" option to filter articles focused on the zoology, environmental sciences ecology, biodiversity conservation, forestry, behavioral sciences, reproductive biology, biochemistry and molecular biology, cell biology, genetics and heredity, evolutionary biology, physiology and developmental biology. We then checked duplication based on the title, abstract and full text. In addition, we examined the reference lists of selected studies to include the publications that were missed by above searching.

    Results 

    We retained 1874 articles related to the Galliformes from the initial 243, 128 publications that were found. About 91.4% focused on one or two species, and 85.0% were conducted within a short duration, typically 1-2 years. The majority of the articles concentrated on macroscopic ecology (55.5%), mainly focusing on habitat selection or habitat use. With recent advances of molecular biology, the studies of taxonomy and phylogenetics rose quickly in last two decades. The study of physiology and biochemistry was no longer limited to simple description but expanded to the mechanisms of phenotype and micro-evolutionary potential. An additional area receiving increasing attention is the conservation of Galliformes, with the assessment of the conservation status and conservation management effectiveness of Galliformes (e.g. species diversity and genetic diversity) becoming the focus.

    Conclusions 

    The studies on Galliformes have made great achievements since 1990, but there are still gaps, particularly in macroscopic ecology, molecular genetics, and conservation. There is an urgent need to enhance long-term monitoring and analysis of population dynamics, and applying different disciplines to galliform conservation. Moreover, life history information of many galliform species is still lacking, which has hindered conservation efforts and effectiveness. In addition, multidiscipline studies and new technologies are not common for galliform studies, and should be encouraged.

  • The Galliformes is one of the most important avian groups throughout the world (del Hoyo et al. 1994; Zhang et al. 2003), and have played a beneficial role to humans as they are widely domesticated and hunted for food, plumage and trading (Fuller and Garson 2000). Galliformes have cultural importance as seen in ancient literatures and artworks (e.g. the characters of "pheasant" and "chicken" appeared in oracle inscriptions in the Shang Dynasty of China) (Peters et al. 2016). In addition, many galliform specimens were captured by some naturalists and explorers from the start of nineteenth century to the 1960s. Hence, it contributed partly to the accelerated decline of some Galliformes because of the great interest in the gorgeous looking and economic value of wild animals (Hennache 2009). Besides hunting, many species of Galliformes have also been threatened by habitat loss (Lawes et al. 2006; Zhou et al. 2015a), human disturbance (Storch 2013), and urbanization (McNew and Sandercock 2013). In particular, the population of many species of Galliformes declined dramatically (Kurhinen et al. 2009; Johnson et al. 2014), such as the Hazel Grouse (Bonasa bonasia), Reeves's Pheasant (Syrmaticus reevesii) and Tibetan Eared-pheasant (Crossoptilon harmani) (Lu and Zheng 2007; Rhim 2010; Zhou et al. 2015a).

    Galliformes have been in a unique position to advance wildlife conservation and research (McGowan and Garson 1995; McGowan et al. 2012) because of their close relationship with human and some species being model animals in animal/avian studies (del Hoyo et al. 1994; Fuller and Garson 2000). Since 1975, the conservation and research of Galliformes have been greatly promoted after the establishment of the World Pheasant Association (WPA) (Tang 1990; Moss et al. 2010). During this time, many techniques (e.g. DNA testing and artificial insemination) were also developed and applied in the research of Galliformes (Gee 1983; Hennache 2009). A brief summary on galliform research before 1989 was presented in the 4th International Symposium on Galliformes in 1989 (Tang 1990). Although there are some recent reviews of Galliformes with focuses on either one topic (e.g. taxonomy or phylogeny) (Crowe et al. 2006; Zheng 2015) or targeted a single species (Moss et al. 2010), the global research status and study areas of Galliformes were not well documented.

    Here, we reviewed the literatures on Galliformes published since 1990, and aimed to (1) review the current study areas on Galliformes, (2) analyze the potential implications of deficiency in the knowledge for a complete understanding of Galliformes, and (3) provide suggestions for future research on Galliformes.

    We conducted a search of the literatures on Galliformes published during 1990‒2016. The search engine, Web of Science, was used for collecting articles with the key words "Galliformes", "Megapodiidae", "Cracidae", "Meleagrididae", "Tetraonidae", "Odontophoridae", "Numididae", "Phasianidae", and the names of each genus of Galliformes. The genera of Galliformes (Table 1) were decided according to the IOC World Bird List (Gill and Donsker 2016) and eBird/Clements Checklist (Clements et al. 2016).

    We used the "Refine Results" option in Web of Science to filter articles and retained the articles written in English. Then we used the "research area" option to filter the articles focused on the zoology, environmental sciences ecology, biodiversity conservation, forestry, behavioral sciences, reproductive biology, biochemistry and molecular biology, cell biology, genetics and heredity, evolutionary biology, physiology, and developmental biology. Topics focusing on agriculture, psychology, virology, medical science, surgery, energy fuels, history, social issues, business economics and food science that was not related to our topic were removed. Finally, all the articles retained were checked manually based on their titles, abstracts and full texts to reduce duplications and were confirmed the research species were not domesticated. The PRISMA flow diagram (Moher et al. 2009) showed the procedure used for selection of studies for this systematic review (Fig. 1).

    For the retained articles, we collected information including author(s), country of author(s), title, abstract, year, study object and research content for each article, and used the country of the first author to report the origin of study. We divided authors' countries into seven regions: Asia (China, Japan, Korea, etc.), Europe (Finland, Spain, United Kingdom, etc.), Africa (South Africa, Nigeria, etc.), Latin America (Brazil, Mexico, etc.), Middle East (Iran, Turkey, etc.), United States of America/Canada, Australia/New Zealand (Marzluff 2016). Meanwhile, the papers were grouped into six subject areas based on the contents (Table 2). Seven articles on fossil studies were classified into the group of taxonomy and phylogenetics, as those articles had a closer relationship with phylogenetics.

    Table  2.  The subject areas and description of the contents
    Subject area Content description
    Macroscopic ecology This category mainly included the studies about habitat use (selection/preference), home range and movement, population size and population dynamic, breeding ecology, and the possible influence of human disturbance on Galliformes
    Molecular ecology This category mainly included the studies concerned with population genetics, genetic variability, genetic diversity, genomics, etc., but the articles on molecular taxonomy and phylogenetics were excluded, as they were categorized into Taxonomy and phylogenetics
    Taxonomy and phylogenetics This category mainly included the studies regarding taxonomy and those investigating the evolutionary relationship between species, of which genetic and morphological methods were commonly used
    Physiology and biochemistry This category mainly included physiology, biochemistry, cell biology, endocrinology, morphology and anatomy
    Conservation This category mainly included the studies specialized in assessment of the conservation status of the species of Galliformes, reintroduction of endangered species, and maintaining genetic diversity. Although most articles in relation to macroscopic ecology also discussed the conservation implications of their results, they were not included in this category because of their primary objectives
    Others This category was split into two themes: Ethology (behavioral studies of Galliformes, but the articles discussing territorial behavior, flocking behavior, and foraging behavior were categorized into Macroscopic ecology as they were often combined with ecological pressures) Research overview (review studies, such as trends in grouse research)

    We used SPSS 21.0 (SPSS Inc., Chicago, IL, USA) for data analysis. We employed Spearman correlation analysis to assess the relationship between the number of articles in each region and the number of genus in the corresponding region. In order to test whether there was a significant influence of the 23rd International Ornithological Congress held in Beijing in 2002 on the research of Galliformes, we used independent samples t test to compare the number of articles published each year before and after 2003 in this study.

    Of the 1874 retained articles, nearly half (49.4%) were from United States of America/Canada, and followed by Europe (26.7%), Asia (14.6%), Latin America (3.6%), Africa (2.1%), Australia/New Zealand (2.0%), and Middle East (1.7%). The average growth rate was 37.9% over the years, and the number of articles after 2003 had a great increase compared with that before 2003 (Independent samples t test, t25 = - 20.7, p < 0.001) (Fig. 2). Regions with more genera of Galliformes had more publications (Fig. 3, Spearman correlation analysis, r = 0.937, p = 0.002).

    Most studies (85.0%) were conducted within a short duration, typically 1-2 years, and 91.4% of all studies focused on one or two species. There were 224 studies concentrating on Sage Grouse (Centrocercus urophasianus), 150 on Wild Turkey (Meleagris gallopavo), and 145 on Northern Bobwhite (Colinus virginianus). Recently, an increasing number of long-term or multiple species studies occurred. Sun et al. (2007) monitored the Chinese Grouse (Tetrastes sewerzowi) in Gansu Province for more than 30 years, and the study interests have covered habitat preference, home range and movement, and nest site selection. Clawson et al. (2015) conducted a 50-year study of the abundance and hunting effect of Wild Turkeys in Missouri, USA, and found that the number of turkeys had reached the maximum capacity of the local environment in the 1980s. In addition, those studies on multiple species usually focused on the phylogenetic relationship among the species (e.g. Crowe 2010; Galla and Johnson 2015).

    A majority of Galliforme research concentrated on macroscopic ecology, followed by molecular ecology, physiology and biochemistry, taxonomy and phylogenetics, conservation and some other field research (Fig. 4). The early studies on Galliformes mainly focused on physiology (e.g. Onyeyili et al. 1992; Onyeanusi et al. 1993), descriptions of reproductive biology (e.g. Follett and Pearce 1990; Follett et al. 1992; Ancel and Visschedijk 1993), and identifying molecular markers (e.g. Hanotte et al. 1991; Matzke et al. 1992). However, more research began to focus on macroscopic ecology (n = 1026) since 2003, with the proportions rising rapidly over the study period (Fig. 5).

    Macroscopic ecology

    The research on the macroscopic ecology of Galliformes mainly concentrated on habitat selection or habitat use (34.1%), reproductive ecology (22.3%), and population studies (25.3%), and there is a rising trend (Fig. 6).

    As habitat use has a direct impact on species survival and individual fitness (e.g. Block and Brennan 1993), many articles assessed habitat characteristics of Galliformes, such as topography (e.g. Tirpak et al. 2008; Zhou et al. 2015a), vegetation type (e.g. Chávez-león et al. 2004; Dzialak et al. 2011; Anich et al. 2013) and climate change (e.g. Kvasnes et al. 2014). The home range or territory of the Galliformes and the influence factors, including habitat characteristics, were also interested by many researchers at the early stage (e.g. Iqubal et al. 2003). It has been found that the home range sizes of Galliformes varied with the gender, seasons, breeding period, and food abundance (e.g. Fearer and Stauffer 2003; Xu et al. 2009; Wang et al. 2012b; Janke and Gates 2013).

    The application of Species Distribution Models in analysis of spatio-temporal variations of habitat selection or habitat suitability became popular especially at the beginning of the 21st century (Jones 2001; Fearer and Stauffer 2003; Xu and Zhang 2011; Coates et al. 2016; Li et al. 2016). Lots of researchers have processed the studies on Galliformes at multiple spatial scale (e.g. Dzialak et al. 2012; Ross et al. 2016), and their results showed that the habitat use patterns of some species varied at different spatial scales (Dzialak et al. 2012), whereas those of some species were similar at different spatial scales (Thogmartin 1999). As regards the temporal scale, researchers conducted these studies at different time intervals, including different seasons, life history stages or years under the background of climate changes, which further influenced the perception of habitat availability and habitat selection (Jones 2001; Dzialak et al. 2011; Kvasnes et al. 2014).

    Habitat loss or fragmentation have negative impacts on many Galliformes, especially pheasants (e.g. Jones 2001; Deng and Zheng 2004; Lawes et al. 2006), and can negatively influence population distribution (e.g. Deng and Zheng 2004; Zhou et al. 2015a), nest survival (e.g. Goddard and Dawson 2009) and increase individual mortality (e.g. Robinson et al. 2016). Specially, more and more research has paid attention to the impact of the human footprint or human disturbance on Galliformes (e.g. Froese et al. 2015; Tanner et al. 2015; Zhang et al. 2015; Smith et al. 2016).

    Reproductive ecology is also an important aspect of macroscopic ecological studies on Galliformes (Jones 2001). In additional to recording breeding parameters like egg size, clutch size and incubation period (Hernández et al. 2003), there are more efforts focusing on breeding habitat use or nest site selection (Jones 2001). A great number of results stated that the vegetation canopy density was one of the main factors related to nest site selection of pheasants (e.g. McNew and Sandercock 2013; Wu et al. 2013). However, it was controversial about the influence of the vegetation cover on the nest fate (Lu and Zheng 2003; Rhim 2012; Khalil et al. 2016). Synthetic reviews suggested that high nest survival rate may be attributed to the extended breeding season (Jansen and Crowe 2005) and available supplemental food sources (Sandoval and Barrantes 2012). Meanwhile, the predation (Ellis-Felege et al. 2013; Carpio et al. 2014; Capdevila et al. 2016; Lyly et al. 2016), competition (Robel et al. 2003; Hämäläinen et al. 2012), extreme weather condition (Kobayashi and Nakamura 2013) and temperature effects (Xu et al. 2008) were likely to be the principal causes of nest failure.

    As the main natural factors, those causes mentioned above contributed to the decrease in population size and density (e.g. Sučić 2008; Rolstad et al. 2009). For the non-natural factors, a general consensus emerged that hunting and human disturbance were the most important reasons of the rapid decline of the population size and density of Galliformes (e.g. Franco et al. 2006; Stiver et al. 2008; Hörnell et al. 2014). However, some researchers hold different opinions that reasonable hunting and moderate interference have no significant influence on population density and survival rate (Williams et al. 2004) as the species were found to modify their behaviors and spatial movements to increase their habitat use (Brøseth and Pedersen 2010). The self-regulating mechanism of maintaining the relatively stable population continues to fascinate ecologists of population ecology (Moss et al. 2010).

    Molecular ecology

    Basic molecular genetics are used to study genetic diversity differences among populations to verify the ecological theories (Bouzat 2000), whereas recent studies turned to changes of the genetic structure under different circumstances (e.g. Bellinger et al. 2003; Gu et al. 2012; Dong et al. 2013). For instance, Huang et al. (2007) found that the genetic diversity of Rusty-necklaced Partridge (Alectoris magna) increased with latitude, altitude, and climate stability, whereas habitat fragmentation (Benedict et al. 2003) reduced genetic diversity of ptarmigan populations. Huang et al. (2005) showed that the peripheral populations that were not isolated exhibited higher genetic diversity than isolated populations. Low genetic variation and diversity were often considered to contribute to the extinction of species when population size was small (Johnson and Dunn 2006). As an important source of genetic variation in populations, introgressive hybridization is widespread (Barilani et al. 2007b). The genetic integrity of the Rusty-necklaced Partridge was shown to be at risk from introgressive hybridization, and the introgressive hybridization may disrupt local adaptations in natural populations (Barilani et al. 2007a) and pollute the gene pool of wild populations (Barilani et al. 2007b). Although unidirectional introgression did not reduce genetic diversity of some species like partridges, it affected the balance of gene flow among populations (Chen et al. 2016).

    The methods of the genetic diversity research have been used to address questions based on morphological traits, biochemical markers, molecular markers, and information from whole genome sequencing (Powell et al. 1996). In recent years, applications using molecular markers, such as Restriction Fragment Length Polymorphism (RFLP) and Simple Sequence Repeat microsatellite (SSR) for testing the species differences in genetic structures have become popular. The technique based on microsatellite markers has become one of the most advanced techniques of analyzing molecular markers due to the high polymorphism (Vignal et al. 2002); and the publications accounted for 26.6% of all the articles in this category. Zhou and Zhang (2009) assessed the isolation and characterization of microsatellite markers of Temminck's Tragopan (T. temminckii), a threatened species in China, which provided means for studying gene flow and genetic diversity of the species. Some studies employed nuclear or mitochondrial marker to study phylogenetic relationships, such as Birks and Edwards (2002) studied the phylogeny of the megapodes (Megapodiidae) based on nuclear and mitochondrial DNA sequences and showed an early split within the megapodes, leading to two major clades. Others used the molecular technique for sex identification, which facilitated the assessment of the sexual ration and related questions in wild population. Wang and Zhang (2009) designed a pair of primers (sex1/sex2) for sex identification in Brown Eared-pheasant (C. mantchuricum) based on the mechanism of PCR amplification of CHD fragments; these primers were found to be more sensitive than P2/P8 and can also be used for sex identification in other species of Phasianidae and Passeriformes.

    Taxonomy and phylogenetics

    Researchers have paid more attention to the taxonomy and phylogenetics of Galliformes (Moulin et al. 2003; Lu 2015). Most studies of taxonomic status were conducted by using genetic methods. For example, Chang et al. (2008) discovered that phylogeographic monophyly and large genetic distance existed between the Hainan Peacock-pheasant and the Grey Peacock-pheasant (Polyplectron bicalcaratum katsumatae) by using molecular markers, including the mitochondrial cytochrome b gene and one loci. However, only several articles tested the taxonomy and phylogenetics by using morphological methods. As the morphological features of species might vary considerably with diet and habitat, the traditional morphological identification technology also had obvious defects, which require professional ornithologists to review a large amount of literatures for identification (Kayvanfar et al. 2015).

    Researchers also analyzed the genomes to identify phylogenetic relationships of different species (e.g. He et al. 2009; Jiang et al. 2014; Zhou et al. 2015b), aiming to clarify the relationship among genera, species or subspecies (Huang et al. 2007; Chen et al. 2015; Persons et al. 2016). For example, Ren et al. (2016) suggested that the genus Crossoptilon was the sister of the genus Lophura. The phylogenetic relationship among Phasianidae species has presented great challenges (Bush and Strobeck 2003). In 2010, based on mitochondrial genome of 34 species, Shen et al. (2010) provided evidences for clarifying the phylogenetic relationship of the Phasianidae; the conclusion was largely consistent with previous molecular studies based on mitochondrial genes and nuclear segments (Shen et al. 2014). However, the most recent studies have exhibited incongruence regarding the relationships within this order. For instance, Shen et al. (2010) suggested a derived position for turkeys and grouse within the Phasianidae, and placed them sister to each other, while Wang et al. (2013) stated that the turkey and grouse formed a sister group nesting inside the Phasianidae based on data from 88 galliform species and four anseriform outgroups. Some of these inconsistencies may reflect the types of data (mitochondrial or nuclear DNA data) used in analysis (Wang et al. 2013). Therefore additional research, such as fossil records, is needed for better understanding the phylogeny of Galliformes (Thomas 2015).

    Physiology and biochemistry

    Recently the researches of the physiological and biochemical aspect of Galliformes are not limited to the simple description of organs (e.g. nose, intestine), and a series of studies focus on the morphological structure and the mechanism of organs (Kadhim et al. 2010; Bourke and Witmer 2016). For instance, Charvet and Striedter (2008) collected the embryos of the Northern Bobwhite (C. virginianus) and the Budgerigar (Melopsittacus undulatus) at various stages to examine whether the differences in brain region size were due to the different species in cell cycle rates. The results showed that the tectum was initially much smaller but then grew more extensively in parakeets than in quail, and species in adult brain proportions can be traced back to cell cycle kinetics. The researchers also analyzed the kinematics as movements were the mechanically complex activities, which improved our understanding of how these muscles modulate mechanical function (Daley et al. 2009).

    A number of studies investigated physiological coping mechanism to the stress response of Galliformes in wild environment. Some evidence proved that the acute stress can be caused by the sudden prey and human interference. Jankowski et al. (2014) found that the amount of grazing was positively associated with the content of cortisol metabolites on Sage Grouse. In term of the chronic stress, the change of seasons and circadian rhythms were the important impact factors, and they would cause basal corticosterone secreted variation (Follett et al. 1992). By affecting the hypothalamic-pituitary-gonadal (HPG) axis, corticosterone can inhibit the reproduction of Galliformes. Moreover, the effect of corticosterone on reproductive was not only on the decrease content of sex hormone, but also on the offspring sex ratio (Pike and Petrie 2006).

    In general, the hormone levels were influenced by the body size, gender, and were associated with the species of Galliformes (e.g. Jankowski et al. 2014; Corfield et al. 2016). Some evidence also showed that maternal hormones were a good pathway to influence offspring development. For instance, the female Common Quail (Coturnix coturnix) with high concentration of corticosterone could transfer corticosterone to yolk, and may alter offspring growth and adult phenotype (Hayward and Wingfield 2004). Herrington et al. (2016) suggested yolk hormones of maternal origin in Northern Bobwhite have a positive effect on the physiological characteristics of offspring.

    Conservation

    This category specialized in assessment of the conservation status and policy effectiveness of the species of Galliformes on both the species diversity and genetic diversity, and it accounted for 6.7% of remaining articles. Most (45.2%) were conducted by the researchers in the United States of America/Canada, followed by Europe (31.0%). The conservation biologists have made great efforts to improve the conservation effectiveness on Galliformes at different levels. Some researchers analyzed the genetic structure or variation to assess the genetic diversity and then provided suggestions to maintain genetic variability (e.g. Schulwitz et al. 2014), while other scientists studied approaches to increase the individual or population survival rate (e.g. Bernardo et al. 2014; Blomberg 2015). Those measures were focused on habitat protection by establishing the protected areas through programs such as the Conservation Reserve Programs (CRP) in the USA (e.g. Lupis et al. 2005), breeding programs (e.g. Apa and Wiechman 2016), and reintroduction projects (e.g. Baruch-Mordo et al. 2013; Gama et al. 2016). Almost all these articles suggested that more actions should be carried out to maintain the integrity and continuity of habitats (e.g. Bro et al. 2004), and they believed that those actions could contribute to creating favorable living conditions for Galliformes (Gama et al. 2016). Unfortunately, a number of articles also showed that many species were not well protected because of lacking effective local managements and reasonable financial provision (Fuller and Garson 2000; Baruch-Mordo et al. 2013) or the effective conservation techniques (e.g. Apa and Wiechman 2016). In particular, hunting was an important negative impact factor in relation to galliform conservation as it was evident that hunting pressure has contributed to the large part of threatened species (e.g. Fuller and Garson 2000; Blomberg 2015).

    Others

    This category was split into two main themes, i.e. ethology (n = 42) and research review (n = 10). Given that the territorial behavior, flocking behavior, and foraging behavior were categorized into macroscopic ecology as they were often related to ecological environment, the ethology category mainly included social behavior (e.g. Wells et al. 2014; Krakauer et al. 2016), vocal behavior (e.g. Garcia et al. 2012), and imitative learning (e.g. Akins and Zentall 1996). By analyzing the results, it showed that the method using playback of vocalisations has been widely used to survey the behaviors of Galliformes. Using playback, the researchers identified subadults, males and females of the species, analyzed the population structure (Van Niekerk 2010), directionality (Garcia et al. 2012), and tested whether and how the playback calls attracted the mating partners (Van Niekerk 2010).

    The reviews of grouse research suggested that the species and topics varied with time, but more recently conservation and the effect of human disturbance on grouse became hot topics (Höglund 2009; Moss et al. 2010; Storch 2013). The remaining articles summarized the conservation status and species extinctions of Galliformes, which provided a basis for better protection of Galliformes. Many species of the grouse, like Sage Grouse, remained listed for protection (McGowan et al. 2009, 2012). Therefore, the researchers called for the more knowledge and improvement of research techniques to study the endangered and poor-known species, and make great efforts to eliminate the negative impacts on biodiversity (Storch 2013).

    Our study analyzed the galliform-related articles from 1990 to 2016, and the results showed that most articles were from the United States of America, Canada, and Europe. Although the vast majority studies focused on one or two species and were of a short duration, it is gratifying to note that the total number of species being studied, articles and the duration of study period were increasing, and the topic range is more extensive, which was similar to the patterns found for the research on grouses (Moss et al. 2010). Zheng (2015) suggested that galliform research has rapidly progressed since 2000. Our results showed that the year of 2003 was a turning point for the great increase of publications related to the Galliformes, which might be attributed to the language barriers and lack of good communication among researchers from non-English speaking countries, especially in China (Myles and Cheng 2003) before 2003. In 2002, the 23rd International Ornithological Congress was held in Beijing, which might make researchers to recognize the importance of international cooperation and communication, especially for Chinese researchers (Myles and Cheng 2003; Walter 2004). After that, more and more researches on the Galliformes in China were published in English (Zheng 2015).

    Different countries and regions hold some different species of Galliformes (Johnsgard 1999), and our results also show that different countries are inclined to conduct research on the species unique to the region (Fig. 3). For example, 77.6% of turkey (Meleagris) research occurred in the United States, as turkey occurs only in North America and Central America (e.g. Mock et al. 2002; McJunkin et al. 2005; Brautigam et al. 2016). Most of the studies on Francolinus spp. occurred in Pakistan and South Africa (Cohen et al. 2012; Khan and Mian 2013), while nearly two-thirds of the literatures of the genus Syrmaticus were from China (e.g. Zhan and Zhang 2005; Jiang et al. 2007; Ashizawa et al. 2014; Zhou et al. 2015a), as they were mainly distributed in China and Japan.

    There are increasing studies on the conservation and ethology of Galliformes in recent years (Fuller and Garson 2000), whereas such studies in our results just occupied a small part (9.0%). As a matter of fact, a great number of articles regarding macroscopic ecology have discussed the conservation implications of their results, and they are classified into macroscopic ecology due to their primary objectives. Similarly, the articles on territorial behavior, behavioral ecology, flocking behavior and foraging behavior were all related to ecology and thus we regarded them as behavioral ecology under the category macroscopic ecology.

    Although studies on Galliformes have made great achievements, there are still some gaps in macroscopic ecology, molecular genetics and conservation. Galliformes still faces many threats, including climate change, human population growth, deforestation and hunting behaviors (Fuller and Garson 2000; Deng and Zheng 2004; Zheng 2015). Based on the trends of current avian research, we make following suggestions for future research of Galliformes.

    Galliformes conservation

    As a highly threatened taxon in the world, the conservation of Galliformes is a significant topic of the global change, and it is more important in developing countries for increasing conflicts between wildlife and human beings. A clear and science-based plan is needed to improve Galliformes conservation (Watson and Venter 2017). Also, long-term monitoring and comprehensive surveys of the populations and habitats of Galliformes should be conducted (Fuller and Garson 2000), which will help to assess the dynamics of the populations and habitat use patterns for habitat suitability at multi-scales (Zheng 2002; Gregory and Beck 2014), and to build a comprehensive database of Galliformes to improve the conservation effort and management effectiveness (Jones 2001; Zheng 2015). Although a number of management policies and conservation programs have been implemented in some regions, most assessments just focused on small scales or restricted topics with limited implications (Brymer et al. 2016). A more comprehensive monitoring and assessment programs are therefore needed for better use of resources to achieve species or community level conservation goals.

    In addition, Galliformes conservation studies were mainly at the macro and descriptive levels historically, with the molecular genetic mechanisms involved less (Vignal et al. 2002). This study found that the number of the articles on genetic studies was more than that on the species conservation, but most of them having provided limited suggestions or guidelines for conservation. Therefore, interdisciplinary and synthetic approaches of molecular ecology and any other fields should be integrated to promote the development of new knowledge and techniques, so as to fit the present and future needs of conservation (Gama et al. 2016).

    Climate change and adaptive plan

    Global climate change is considered as one of the major threats to biodiversity (Feng et al. 2015), and there is strong evidence that climate change limited the reproduction of some species of Galliformes (Selås et al. 2011), and may have already deduced several species' extinctions (Heller and Zavaleta 2009). Mantyka-pringle et al. (2013) suggested that climate change has negatively interacted with habitat loss, and synergistically continues to pose direct and indirect impacts to species, even contributes to the degradation of biodiversity (Jetz et al. 2007). However, climate change adaptation work was still mainly at the conception stage (Heller and Zavaleta 2009), and most research so far just provided general adaptation recommendations without considering the size and location of each threat (Watson et al. 2013), and few recommendations suggested a process that managers could use to develop an adaptive plan and evaluate its effectiveness (Heller and Zavaleta 2009). As such, there will be a need for specific biodiversity-oriented adaptation planning, from short to long term and from precautionary and robust to more risky or deterministic, to respond to both rapid directional change and tremendous uncertainty (Heller and Zavaleta 2009; Rao et al. 2013; Watson et al. 2013).

    The life history of Galliformes

    Understanding the pattern of change in life history characteristics is the central goal of evolutionary ecology (Martin 1996), and it is also the basis for understanding bird evolution and adaptation to the environment (Wang et al. 2012a). However, while many researchers devoting great efforts to genomics rather than life history in recent years (Zheng 2015), the information on the natural histories of many Galliformes, as of other birds, is still lacking (Lu 2015). Xiao et al. (2016) analyzed all the available information for three key breeding parameters for nearly 10, 000 species of birds in the world, and they found that the information of the reproductive parameters was available for only one-third of these birds. Therefore, research on the natural history of birds should be encouraged to fill these knowledge gaps (Jimenez et al. 2014).

    Cross-disciplinary studies and application of new technologies

    Understanding the scientific questions in ornithological studies not only requires the knowledge of ecology and genetics, but also cell biology, physiology and biochemistry, etc. Multidisciplinary and multiple technology approaches will be more effective to solve the complicated questions of Galliformes, compared to isolated, single-dimensional studies (Fuller and Garson 2000). The interactions among ornithologists and between ornithologists and scientists of other fields or natural resources managers will benefit or are even necessary for the development of new theories and techniques.

    Over the past two decades, researchers have undertaken a lot of work on the application of new technologies (Powell et al. 1996). It is an ongoing challenge to use new technologies to answer the key questions about bird conservation (Wang et al. 2012a). With the development of molecular techniques and computer science applications, ornithological studies are acquiring new tools (Caravaggi et al. 2017). Although molecular technologies have made great breakthroughs in genetic diversity (Huang et al. 2005), taxonomy (Moulin et al. 2003) and phylogenetic (Wang et al. 2013), there is still a need to develop the simple and accurate molecular techniques, such as molecular markers, to inject new impetus into genetic research (Vignal et al. 2002). With the development of whole genome sequencing, it is becoming implementable using population genome to identify the genes linked to local adaptation, which may provide evidences for conservation management (Campbell-Staton et al. 2017). In recent years, computer-centric "3S integration" technology has been developed rapidly and adopted by many researchers. The integrated application of this technology allows for regional investigation and dynamic monitoring, which saves time and human and material resources (Caravaggi et al. 2017), and the work has expanded to experimental data processing and modeling to explain mechanisms such as dispersal and population differentiation (o'Brien and Kinnaird 2008). Research has also evaluated the ecological environment to provide a more scientific basis for bird habitat protection planning and associated decision-making. The world is becoming "smaller" with the development of new technologies and artificial intelligence, and exploring frontier research techniques for study, monitoring, and analyzing patterns and mechanisms of Galliformes ecology is becoming a necessity.

    By reviewing galliform-related articles published from 1990 to 2016, our results showed that the average growth rate was 37.9% over the years. Macroscopic ecology, taxonomy and phylogenetics were the major topics of the studies on Galliformes, accounting for a large part of the current research and research on molecular ecology was on the rise. However, despite the progresses, there is a lack of studies directly applying new knowledge to the conservation of Galliformes, given that the group of birds are facing increased threatens. Moreover, the research on life history represented only a small proportion in the literatures reviewed, with the fact that the knowledge of life history of many galliform species is still missing. Future studies that investigate the basic life history and conduct long-term monitoring of galliform populations and those incorporating different disciplines and new technologies should be encouraged, not only for a better understanding of them, but for better making effective conservation measures.
