Liang D, Li C. Habitat Suitability, Distribution Modelling and GAP Analysis of Przewalski's Gazelle Conservation. Animals (Basel) 2024; 14:149. [PMID: 38200880 PMCID: PMC10778258 DOI: 10.3390/ani14010149] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Revised: 12/14/2023] [Accepted: 12/18/2023] [Indexed: 01/12/2024] Open
Abstract
Although the population of Przewalski's gazelle (Procapra przewalskii) has increased, this species is still threatened by a variety of risk factors, such as habitat loss and fragmentation, grassland fencing, grazing conflict, the segmentation of different populations, and declines in population genetic diversity. In order to determine the potential suitable habitat of Przewalski's gazelle and find a new suitable location for its conservation translocation, we used the MaxEnt model to predict the suitable habitats in Qinghai Province, Gansu Province, and the Ordos Plateau in Inner Mongolia and other regions with historical distribution records. On the basis of the MaxEnt model's prediction of the potential suitable habitat of Przewalski's gazelle, we used GAP analysis to determine the existing protection gaps and provide a new reference for the future protection of Przewalski's gazelle. We found that altitude, temperature, vegetation type, and distance from roads were the main environmental factors affecting the geographical distribution of Przewalski's gazelle. Most of the suitable habitat of Przewalski's gazelle is confined around Qinghai Lake. GAP analysis revealed that most of the suitable habitats of Przewalski's gazelle are not included in the established reserves, and Qinghai Lake National Nature Reserve only covers a small area around Qinghai Lake. The whole reserve only accounts for 7.11% of the area of the suitable habitat for Przewalski's gazelle and 15.79% of the area of the highly suitable habitat for Przewalski's gazelle. We suggest that conservation translocation for Przewalski's gazelle should be put on the agenda. It is necessary to consider reintroducing these gazelles into their potential suitable habitats as a feasible way of establishing new populations and saving this species.

Abstract
Due to human activities and climate change, the habitats of ungulate species on the Qinghai-Tibet Plateau have been greatly affected in recent decades. In this study, the distribution patterns of 19 ungulate species on the Qinghai-Tibet Plateau were identified based on MaxEnt model in the past (1960-1990) and current periods (2000-2015). Then the changes of their habitat distribution and the species richness in different periods were compared. Finally, the Zonation model was used to identify the key protected areas of ungulate species. The results show that the MaxEnt model can well predict the distribution of ungulate species. Most ungulate species are mainly distributed in the southeast of the Qinghai-Tibet Plateau. The distance to lakes and precipitation are the main factors affecting the distribution of most ungulate species. The habitats originally located in the southeast of the Qinghai-Tibet Plateau have mainly extended northeastwards, while the habitats originally located in the northwest has been largely lost. The changes in the habitats of ungulate species in the southeast and northwest are diametrically opposite. The key protected areas identified by Zonation model are mainly located in the southeast of the Qinghai-Tibet Plateau. The existing nature reserves can effectively protect the suitable habitats of the Tibetan antelope, Tibetan wild ass and wild yak. This research can provide scientific basis for coordinating the contradiction between development and protection and promoting the biodiversity conservation on the Qinghai-Tibet Plateau.

Abstract
Fencing is an essential measure for the rehabilitation and conservation of grasslands on the Qinghai-Tibet Plateau. However, its construction could change the distribution and migration of wildlife, thus affecting the integrity of the ecological networks for local wild animal movement. It is of great significance to quantify the potential impact of fencing on ecological network connectivity associated with land-use changes at regional scale. In this study, taking the northern Tibetan Plateau as the study area, we explored the ecological network change using circuit theory approach under different scenarios at county scale. Among them, this study set up four different scenarios according to the economic growth rate, population growth rate and the sustainable development of society and environment. The results showed that: 1) with increased grazing intensity and enhanced human activities from 1990 to 2015, the grasslands of the northern Tibetan Plateau were greatly degraded, most of which was converted into the barren land, and the conversion proportion was as high as 90.84%, which lead to a decreasing trend of the current density of ecological network in most counties and deterioration of ecological connectivity; 2) fencing construction has reduced regional current density, while fencing intensity is positively correlated with current density loss at county scale. Among them, the counties with serious current density loss were distributed in the northwest and southeast regions. The maximum loss ratio is 39.23%; 3) under four different future land use scenarios, coordinated economic, social and environmental development will have a positive effect on the ecological network. The results of the study have important ecological significance for developing reasonable conservation measures for grassland restoration, protecting wildlife, and maintaining regional ecological balance.

Abstract
Globally, migratory ungulates are affected by fences. While field observational studies reveal the amount of animal–fence interactions across taxa, GPS tracking-based studies uncover fence effects on movement patterns and habitat selection. However, studies on the direct effects of fences and fence gaps on movement behavior, especially based on high-frequency tracking data, are scarce. We used GPS tracking on three common African antelopes (Tragelaphus strepsiceros, Antidorcas marsupialis, and T. oryx) with movement strategies ranging from range residency to nomadism in a semi-arid, Namibian savanna traversed by wildlife-proof fences that elephants have regularly breached. We classified major forms of ungulate–fence interaction types on a seasonal and a daily scale. Furthermore, we recorded the distances and times spent at fences regarding the total individual space use. Based on this, we analyzed the direct effects of fences and fence gaps on the animals’ movement behavior for the previously defined types of animal–fence interactions. Antelope-fence interactions peaked during the early hours of the day and during seasonal transitions when the limiting resource changed between water and forage. Major types of ungulate–fence interactions were quick, trace-like, or marked by halts. We found that the amount of time spent at fences was highest for nomadic eland. Migratory springbok adjusted their space use concerning fence gap positions. If the small home ranges of sedentary kudu included a fence, they frequently interacted with this fence. For springbok and eland, distance traveled along a fence declined with increasing utilization of a fence gap. All species reduced their speed in the proximity of a fence but often increased their speed when encountering the fence. Crossing a fence led to increased speeds for all species. We demonstrate that fence effects mainly occur during crucial foraging times (seasonal scale) and during times of directed movements (daily scale). Importantly, we provide evidence that fences directly alter antelope movement behaviors with negative implications for energy budgets and that persistent fence gaps can reduce the intensity of such alterations. Our findings help to guide future animal–fence studies and provide insights for wildlife fencing and fence gap planning.

Pastoral practices, pressures, and human-wildlife relations in high altitude rangelands of eastern Himalaya: A case study of the Dokpa pastoralists of North Sikkim. PASTORALISM 2022.

Abstract
AbstractThe pastoral practices of the Dokpa herders of North Sikkim have been transforming in response to the geo-political and socio-economic changes in the region. Against the backdrop of these changes, this study aims to understand the current state of pastoralism in North Sikkim with three specific objectives: (i) to understand the current rangeland management practices of the Dokpa community; (ii) to examine the social, political and ecological stresses to continuity of traditional pastoral livelihoods; and (iii) to document the baseline on human-wildlife relations. We focused on one of the two subset populations of Dokpa herders of North Sikkim and, using a mixed-methods approach, conducted 12 semi-structured interviews, four key respondent interviews and two focused group discussions. The resource use by the Dokpas is unique, and unlike the rest of the Himalayan range, they access the high-altitude pastures in winters and the lower ones in summer. Pastures in the higher altitudes experience heavier winds, which leads to lower levels of snow deposition — thus ensuring access to dried pasture forage for livestock during the lean season. The decisions pertaining to resource management are taken by the head of the local institution Dzumsa, the Pipon. Primary stresses to the continuation of traditional pastoral practices are fragmentation of pastureland post-Sino-Indian war of 1962 and the consequent establishment of armed forces, livestock depredation by free-ranging dogs followed by wild predators and continued socio-economic marginalisation of the pastoralists under a supposedly egalitarian institutional regime. Extreme climatic events in the recent past have also contributed to significant livestock loss. Dokpa transhumant practices are on an overall decline, with most members of the younger generation shifting to non-herding livelihoods. The availability of alternate livelihood options with the improved connectivity, access to education and development of the tourism industry has led to changing aspirations of the younger generations. In only two of the twelve households we surveyed, the younger generation continues herding, while the rest have moved to the cities and towns. In terms of human-wildlife relations, the respondents mostly hold a positive attitude towards wildlife and conservation actions despite livestock predation by wild predators, since the free-ranging dogs cause the highest livestock loss. With the inputs from the Dokpas, we provide recommendations towards a facilitative environment for the continuation of the traditional herding in the region, which is critical for the survival of pastoralism in North Sikkim, presently hinged on less than two dozen of elderly Dokpas.

Abstract
Grassland has always had a difficult economic–ecological relationship, as coordination between its ecological conservation and the sustainable development of animal husbandry is required. Nature-based Solutions (NbS), who make full use of the natural ecosystem services, have successfully solved some economic–ecological issues, but still have unclear implementation prospects for grassland management. The Xilin Gol grassland is one of the most typical pastoral areas in China; there is a village chief named Bateer, who has already used NbS for grassland management. To confirm whether the solutions employed by Bateer have been effective for both increasing economic profits and protecting grassland ecosystem, we interviewed him, and many other herdsmen, using questionnaires about their livelihood. Based on these questionnaires, we calculated and compared their income–cost ratios. Meanwhile, we analyzed the NDVI variations inside their rangelands through high-resolution remote sensing images. The results showed that the herdsmen in Bateer’s village had a much higher disposable income and income–cost ratio than others, and their rangelands also had a higher value and a more obvious increasing trend of NDVI. Bateer’s success proves that the NbS can also play a positive role in grassland management, which can provide a valuable guidance for economic–ecological coordination in pastoral areas.

Abstract
To understand why Procapra przewalskii does not show the same white myopathy as sheep in Se-deficient regions and to provide reference for feeding nutrition level of artificial population and selection of wild reintroduction areas in the later period, a Se-deficient model was established. The mineral elements content, physiological and biochemical parameters in blood and serum metabonomics were determined. In the Se-deficient group compared with the control group, the Se content was highly significantly lower (P < 0·01), and the Cu content was significantly higher (P < 0·05). The activity of glutathione peroxidase was significantly lower (P < 0·05), but total superoxide dismutase was significantly higher (P < 0·05). By matching the mass spectrum data of compounds with the Kyoto Encyclopedia of Genes and Genomes (KEGG database), eighty-six types of differential metabolites in the serum were identified. The main metabolic pathways included secondary bile acid biosynthesis, biosynthesis of unsaturated fatty acids and pyrimidine metabolism. Further analysis showed that there were seven different metabolites in pyrimidine metabolism pathway between the two groups. And there was no significant difference in erythrocyte, Hb and total antioxidant capacity between the two groups (P > 0·05). The above results showed that the differential metabolism of substances exhibited complementary functions, thus alleviating some adverse effects and resulting normal activities of P. przewalskii can be carried out under the condition of dietary Se content lower than 0·05 mg/kg.

Abstract
Selenium (Se) is an essential mineral nutrient for animals. Se deprivation can lead to many disorders and even death. This study investigated the response of Przewalski's gazelle (P. przewalskii) to Se-deprived environment. We found that Se deprivation in soil and forage not only influenced the mineral contents of the blood and hair in P. przewalskii, but also severely disrupted their blood parameters. We identified significant changes in the abundance of 146 proteins and 25 metabolites (P < 0.05) in serum, including the selenoproteins L8IG93 (glutathione peroxidase) and F4YD09 (Cu/Zn superoxide dismutase). Furthermore, the major known proteins and metabolites associated with the Se stress response in P. przewalskii were Cu/Zn superoxide dismutase, the vitamin K-dependent protein C, the C4b-binding protein alpha chain, complement component C7, lipase linoleic acid, peptidase D, thymidine, pseudo-uridine, L-phenylalanine, L-glutamine, PGA1, and 15-deoxy-delta-12,14-PGJ2. The main signaling pathways involved included complement and coagulation cascades, metabolic pathways, and stress granule formation. Our results indicate that the intake of Se-deficient forage elicited an oxidative stress response in P. przewalskii. These findings provide insights into the response mechanisms of this threatened gazelle to Se stress, and enable the development of conservation strategies to protect populations on the Qinghai-Tibetan Plateau. SIGNIFICANCE: This study is the first to point out the presence of oxidative stress in P. przewalskii in selenium-deficient areas through proteomics and metabolomics studies. These findings should prove helpful for conservation efforts aimed at P. przewalskii populations and maintenance of the integrity of their ecological environment.

Abstract
Habitat connectivity is indispensable for the survival of species that occupy a small habitat area and have isolated habitat patches from each other. At present, the development of human economy squeezes the living space of wildlife and interferes and hinders the dispersal of species. The Przewalski’s gazelle (Procapra przewalskii) is one of the most endangered ungulates, which has experienced a significant reduction in population and severe habitat shrinkage. Although the population of this species has recovered to a certain extent, human infrastructure severely hinders the gene flow between several patches of this species. Therefore, we used the maximum entropy (MaxEnt) model to simulate the habitat suitability of the Przewalski’s gazelle. In addition, we combined habitat suitability and ecological characteristics of the species to obtain eight habitat patches. Finally, we used the least-cost path (LCP) and circuit theory based on the resistance model to simulate the landscape network of this species. The results showed that habitat patches and connectivity in the east of the Qinghai Lake were crucial to the communication between populations of the Przewalski gazelle, and our study provided important reference for the distribution of important habitats and the construction of corridor between patches. Our study aimed to provide habitat networks and maintain landscape connectivity for achieving the fundamental goal of protecting and revitalizing populations of the Przewalski’s gazelle.

Abstract
Grazing exclusion using fences is a key policy being applied by the Chinese government to rehabilitate degraded grasslands on the Tibetan Plateau (TP) and elsewhere. However, there is a limited understanding of the effects of grazing exclusion on alpine ecosystem functions and services and its impacts on herders' livelihoods. Our meta-analyses and questionnaire-based surveys revealed that grazing exclusion with fences was effective in promoting aboveground vegetation growth for up to four years in degraded alpine meadows and for up to eight years in the alpine steppes of the TP. Longer-term fencing did not bring any ecological and economic benefits. We also found that fencing hindered wildlife movement, increased grazing pressure in unfenced areas, lowered the satisfaction of herders, and rendered substantial financial costs to both regional and national governments. We recommend that traditional free grazing should be encouraged if applicable, short-term fencing (for 4-8 years) should be adopted in severely degraded grasslands, and fencing should be avoided in key wildlife habitat areas, especially the protected large mammal species.

[PMID: 31129266 DOI: 10.1016/j.jprot.2019.103389] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2018] [Revised: 05/10/2019] [Accepted: 05/14/2019] [Indexed: 12/27/2022]
Abstract
The Przewalski's gazelle shows long-term survival in a selenium (Se)-deficient environment, but fails to exhibit obvious pathological manifestations. To reveal proteomic changes in the Przewalski's gazelle in response to Se-deficiency, twenty Przewalski's gazelle were randomly divided into control group and Se-deficient group. After induction of Se-deficiency animal model, blood samples were collected from eight animals. An isobaric tag for relative and absolute quantitation (iTRAQ)-liquid chromatography-tandem mass spectrometry (LC-MS/MS) proteomics approach was employed to explore blood protein alterations and potential mechanisms of the response to Se-deficiency challenge. Se deficiency contributed to a remarkable change in blood Se levels and routine blood indexes. In proteomic analyses, 130 proteins were differentially accumulated in the Se-deficient and control groups. The differentially expressed proteins were annotated mainly as single-organism process, extracellular region, or binding, respectively, and they were highly enriched in the coagulation and complement cascades. Protein-protein interaction analysis showed several important nodal proteins involved in the regulation of binding, cellular biochemical processes, and signal transduction pathways. To our knowledge, this study is the first to comprehensively analyze blood protein changes in the Przewalski's gazelle under Se-deficient conditions, which reveal that this species has developed physiological mechanisms of adaptation in response to Se-deficiency stress. SIGNIFICANCE: The present study is the first to comprehensively analyze alterations in the protein profiles induced by Se deficiency in the blood of the Przewalski's gazelle, showing that Se-deficiency contributed to a significant reduction in blood Se levels and marked changes in blood parameters, which will likely contribute to a better understanding of the molecular mechanisms of the changes in protein abundance in the Przewalski's gazelle in response to Se-deficiency stress.

Abstract
This study was conducted in the Hudong-Ketu area to the south-east of Qinghai Lake, China, one of the main habitats of Przewalski’s gazelle (Procapra przewalskii). The objective was to understand herdsmen’s perceptions and attitudes towards rangeland fencing, gazelle protection and control of wolf predation on livestock. A total of 251 families of herdsmen were randomly selected for face-to-face interviews in March 2011 (100 families), 2012 (65 families), and 2013 (86 families). The interview results showed that the herdsmen had a strong willingness to protect the gazelle and most of the interviewees were willing to reduce the height of their rangeland fences, but few herdsmen were willing to completely remove fencing without compensation. Although the responses from the herdsmen suggested that they would like to see some gazelle grazing on their rangeland, they considered the gazelle as a competitor with their livestock for grass herbage. The majority of herdsmen interviewed had suffered from some loss of livestock due to wolf predation, and most of them considered wolf predation a serious problem, particularly to their sheep. Most of them thus did not want to see an increase in the number and distribution of wolves, but none of the interviewees would kill wolves. The herdsmen’s belief in Tibetan Buddhism played an important role in influencing the attitudes of the herdsmen towards wolves and the gazelle. These interview results suggest that the herdsmen, as key stakeholders, need to be considered and involved in the development and implementation of any program to protect the gazelle, recovery of wolf populations and maintain rangeland ecosystems.

A spatially explicit model of functional connectivity for the endangered Przewalski's gazelle (Procapra przewalskii) in a patchy landscape. PLoS One 2013; 8:e80065. [PMID: 24250829 PMCID: PMC3826712 DOI: 10.1371/journal.pone.0080065] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2013] [Accepted: 10/08/2013] [Indexed: 12/02/2022] Open
Abstract
Background Habitat fragmentation, associated with human population expansion, impedes dispersal, reduces gene flow and aggravates inbreeding in species on the brink of extinction. Both scientific and conservation communities increasingly realize that maintaining and restoring landscape connectivity is of vital importance in biodiversity conservation. Prior to any conservation initiatives, it is helpful to present conservation practitioners with a spatially explicit model of functional connectivity for the target species or landscape. Methodology/Principal Findings Using Przewalski’s gazelle (Procapra przewalskii) as a model of endangered ungulate species in highly fragmented landscape, we present a model providing spatially explicit information to inform the long-term preservation of well-connected metapopulations. We employed a Geographic Information System (GIS) and expert-literature method to create a habitat suitability map, to identify potential habitats and to delineate a functional connectivity network (least-cost movement corridors and paths) for the gazelle. Results indicated that there were limited suitable habitats for the gazelle, mainly found to the north and northwest of the Qinghai Lake where four of five potential habitat patches were identified. Fifteen pairs of least-cost corridors and paths were mapped connecting eleven extant populations and two neighboring potential patches. The least-cost paths ranged from 0.2 km to 26.8 km in length (averaging 12.4 km) and were all longer than corresponding Euclidean distances. Conclusions/Significance The model outputs were validated and supported by the latest findings in landscape genetics of the species, and may provide impetus for connectivity conservation programs. Dispersal barriers were examined and appropriate mitigation strategies were suggested. This study provides conservation practitioners with thorough and visualized information to reserve the landscape connectivity for Przewalski’s gazelle. In a general sense, we proposed a heuristic framework for species with similar biological and ecological characteristics.
