We investigated the population genetic structure of two sympatric ungulates, roe deer Capreolus capreolus and Northern chamois Rupicapra rupicapra, in a mountain area of the central Italian Alps (Trentino, northern Italy). A total of 122 chamois and 72 roe deer samples were genotyped by two species-specific panels of 11 polymorphic microsatellite loci and analyzed by aspatial and spatially explicit analyses. While the roe deer population resulted unstructured, a clear population structure was detected in chamois, with two main groups, one inhabiting the eastern and the other spread in the western part of the study area. Landscape genetics analysis confirmed these scenarios and revealed a different effect of landscape on gene flow. An IBD (Isolation-By-Distance) model best explained genetic variation in roe deer, while IBR (Isolation-By-Resistance) was found as the process underlying genetic variation patterns in chamois, suggesting arable lands, coniferous forests, watercourses, and main roads as potential barriers. Species distribution and landscape use might explain these results: roe deer mostly occupy valley floors relatively connected to each other, and their spatial behavior may promote gene flow across areas. On the other hand, chamois prefer higher elevations and their movements may be hindered by valleys, rivers, and road networks. This study highlights the different impacts of natural and anthropic landscape elements on gene flow in two sympatric species, resulting from their different ecological requirements.","PeriodicalId":51044,"journal":{"name":"European Journal of Wildlife Research","volume":"49 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140617254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many studies of the masting effects on population dynamics of wild boars have been conducted in cool- and warm-temperate forests; however, studies on wild boar populations inhabiting subtropical forests, which have more diverse plant resources than temperate forests, are limited. The mast seeding effects of Castanopsis sieboldii on the reproductive schedule and population fluctuations of wild boars inhabiting the subtropical climate zone of the Ryukyu Islands (Japan) were investigated using 14 years of camera trap data. The reproductive schedule, estimated based on the emergence of piglets, varied in response to masting. The piglet emergence during the January–February period was higher in the years after masting than in the years that followed non-masting events, evidencing that the reproductive season started earlier and lasted longer in the years after masting. The Bayesian state-space model incorporating direct density-dependence and masting effects revealed that the relative population size was negatively affected by the population size of the previous year and positively affected by the previous year’s occurrence of masting. These observations indicate that masting is a critical factor driving population dynamics of wild boars living in subtropical forests and also highlight the importance of mast seeding effects on population fluctuations of wild boars when developing management plans for these animals.","PeriodicalId":51044,"journal":{"name":"European Journal of Wildlife Research","volume":"38 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140596708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the context of disease management interventions, different approaches such as vaccination and culling may be deployed in adjacent areas resulting in a need to identify previously vaccinated individuals to avoid losses of vaccination benefits. Badgers (Meles meles) have been identified as a wildlife reservoir of bovine tuberculosis in several countries. In England, the primary means of controlling disease in badger populations has been culling, although policy also includes the use of badger vaccination. Vaccination and culling can therefore increasingly take place in adjacent areas. The current means of marking vaccinated badgers is to apply a fur clip; however, the performance of this method has not been assessed. In this study, we assessed the field performance of livestock markers not previously trialled on badgers. We also assessed the performance of fur clips in terms of (a) how likely they are to be detected on recapture and (b) their detectability using remote cameras. None of the livestock markers trialled persisted well on badger fur. Detectability of fur clips on re-captured badgers fell to 50% in adult badgers by approximately 3 months from application. In cubs, detectability fell to less than 50% within 3 weeks of application. We suggest it is highly likely that, if vaccination and culling were carried out in adjacent areas and fur clipping was the primary means of determining vaccination status, a proportion of recently vaccinated badgers would be removed, particularly cubs. This has important implications for disease control, and we suggest options for minimising such losses.","PeriodicalId":51044,"journal":{"name":"European Journal of Wildlife Research","volume":"4 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140313638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A general movement of species toward higher altitudes, in search of suitable sites, is being observed. In the case of the Italian Alps, an expansion of the brown hare (Lepus europaeus) is possible within the zones occupied by the mountain hare (Lepus timidus), which frequents higher altitudes. The risk is an increase in the hybridization and a contraction of the mountain hare’s range. In this study, we analyzed the hunting bags (weighted by the number of active hunters each year) of brown and mountain hares from the period of 1980–2020, in the province of Sondrio (Central Alps) in northern Lombardy (N-Italy), with the aim of (i) highlighting any population trends in relation to climate change, (ii) identifying altitudinal changes in the distribution of the two species over the years, (iii) identifying the environmental variables that influence the distribution of the two species, and (iv) creating suitability maps in the study area. To study population trends, the hunting bag data were corrected by dividing the number of hare shot by the number of active hunters in that year. For both species, no population trends were found between 1980 and 2020. Weather variables do not seem to have influenced population trends. No significant trends in the altitudinal distribution of the two species were observed over the period investigated. The results indicate that the two species select different altitudes, with the exception of the belt between 1600 and 1800 m a.s.l. Both species select meadows.","PeriodicalId":51044,"journal":{"name":"European Journal of Wildlife Research","volume":"44 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140313824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the same time, responses to wildlife often relate to cultural contexts. In this study, emotions associated with wolves and wild boars were examined in two samples taken from Turkish (N = 637) and German (N = 415) university students. As expected, different patterns of emotional responses emerged in the two samples. For example, while negative emotions such as disgust and anger toward the wild boar were prevalent in the Turkish sample, positive emotions such as joy, surprise, and interest occurred in the German sample. Significant differences between the emotions associated with wolves and wild boars were revealed in both samples. In the Turkish sample, wolves caused stronger fear, joy, and interest, whereas wild boars caused stronger anger and disgust. In the German sample, wolves caused stronger joy, surprise, interest, and sadness, whereas wild boars caused stronger disgust. Fear, however, was expressed toward both wolves and wild boars in both samples. The predictive power of emotions on students’ intentions to protect wild boars and wolves was examined as well as intentions to protect human interests against these animals. Disgust was the strongest (negative) predictor of a protection intention toward the wild boar in the Turkish sample. In the German sample, joy and interest were the emotions that best predicted conservation intentions (positive) for both animals.","PeriodicalId":51044,"journal":{"name":"European Journal of Wildlife Research","volume":"294 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140203540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Balochistan, recognized as one of the most vulnerable regions to climate change in Pakistan, has limited data on the distribution and population status of this species. To address this gap, our study aims to assess the spatial and temporal distribution and population trend of Sindh ibex in the Khuzdar and Lasbela districts of Balochistan. The study covered an area of approximately 45,123.97 km2. It involved a double-observer survey at ten sites from 2019 to 2022, using the BBRecapture package in the R programming language to estimate ibex population trend and dispersion. We provided a comprehensive update of the species geographic range, along with estimates of its current abundance and population trends. Over the course of four years, the ibex population fluctuated. The ibexes detected dropped from 720 (male to female ratio 1:1.21) and 710 (male to female ratio 1:1.08) in 2019 and 2020, respectively, to 550 (male to female ratio 1:1.35) and 548 (male to female ratio 1:1.09). Overall, this study provides valuable insights into the population trends, gender ratios, habitat preferences, and density of Sindh ibex in Balochistan over the four-year period. These findings contribute significantly to the baseline data on the species ecology and will further help in the conservation of these species at local scale.","PeriodicalId":51044,"journal":{"name":"European Journal of Wildlife Research","volume":"30 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140171329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whether Assamese macaques living in limestone habitats in Guangxi undergo cyclical shifts in their gut microbiota in the face of seasonal environmental changes, especially abundant rainfall from May to October and significantly reduced rainfall from November to April, remains unelucidated. In this study, 16S rRNA sequencing was used to analyze the gut microbiota composition of wild macaques in the limestone forest, Guangxi, and the seasonal pattern of their gut microbiota was explored using the combined data of diet composition, food availability index, and climate factors. The results indicated that Firmicutes and Proteobacteria were the dominant phyla in the gut of the Assamese macaques, and over 98% of these bacterial taxa exhibited no significant seasonal differences in relative abundance and the community structure of gut microbiota. This may be related to their diet throughout the year containing over 90% of young leaves and fruits, and the intake of mature leaves and flowers closely associated with the gut microbiota lacks significant seasonal differences, which also corresponds to the relative stability of the gut microbiota. Additionally, rainfall and humidity are closely related to the gut microbiota, but their effect was insufficient to significantly fluctuate the gut microbiota, indicating that the climatic change is tolerable for the macaques. Combined with the feeding choices of these macaques in the limestone habitat, their digestive strategy from the perspective of gut microbiota was determined.","PeriodicalId":51044,"journal":{"name":"European Journal of Wildlife Research","volume":"168 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140116704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Iberian wolf (Canis lupus signatus) is one of the top predators in the Iberian Peninsula, and monitoring its packs is essential to understand its distribution and mitigate conflicts arising from livestock predation. We performed a captivity-based study evaluating the effectiveness of five attractants (beef extract, cadaverine, Fatty Acid Scent (FAS), lynx urine and valerian extract) on wolf detection. To accomplish this objective, Jacobs selectivity index and generalized linear models were employed to assess the attractiveness and induced behaviour of each attractant. Subsequently, the three most effective attractants, combined or not with a bait, were tested in the field and analyzed using generalized linear mixed models. The five attractants tested elicited different behavioural responses in the wolves in captivity, including smelling, rubbing, rolling, marking and licking. Among the captive wolves, cadaverine, FAS and lynx urine emerged as the top three preferred attractants. In the field tests with these three attractants cadaverine remained the most preferred option. The inclusion of bait did not have any significant effect on the wolf’s visitation rates. Our results show that employing species-specific attractants can significantly improve the efficiency of carnivore surveys conducted in the field. Specifically, cadaverine was the most effective attractant for wild Iberian wolves. Consequently, the careful selection of an appropriate attractant becomes crucial to attain the precise objectives of the study, such as camera trapping, bait deployment or DNA sampling.","PeriodicalId":51044,"journal":{"name":"European Journal of Wildlife Research","volume":"39 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140116701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
