The European ground squirrel faces potential extinction in various countries, with populations decreasing throughout the entire range. Particularly in the Czech Republic, the mosaic landscape of private backyard gardens is now a vital habitat for the species. However, information regarding crop risks and effective, non-invasive measures for conflict mitigation are almost inexistent. To address this, we conducted field experiments examining the risk of damage for 18 common crops in backyard gardens, and tested non-invasive physical barriers to protect small plots. Our research reveals that simple fences are highly effective in safeguarding susceptible crops, particularly in areas with a high squirrel density. These findings contribute to the development of more species-specific, ecologically-based management plans and help create a sustainable future for the European ground squirrel.

The land snail Elona quimperiana is listed in annexes II and IV of the Europe Habitats Directive. In this study, phylogenetic relationships between populations of this protected species from its whole distribution range were reconstructed based on the sequencing of two mtDNA gene fragments (COI and 16S rRNA) and one nDNA gene fragment (ITS2). Haplotype networks were also generated for the COI and 16S rRNA gene fragments. Results yielded three main intraspecific phylogroups, here designated as the lineages Brittany-Spain, Basque, and Navarre-Rioja. This last lineage had not been identified previously. Genetic distances between the three main phylogroups suggest they could have originated by allopatric fragmentation before the Last Glacial Maximum, and then separately evolved in three refugia in the Iberian Peninsula. We here propose that each phylogroup is considered an Evolutionarily Significant Unit. Through extended sampling, we were able to delimit the geographic distribution of all three lineages. Our genetic results support post-glacial colonization of this species from the north-eastern Iberian Peninsula to Brittany in NW-France as proposed previously, and rule out its recent anthropic introduction.

Some of the hardest challenges in conservation are those situations which occur when endangered species' and human interests collide. The European ground squirrel Spermophilus citellus, a mainly herbivorous rodent which feeds on agricultural crops when available, is an endangered species facing extinction in several countries. Sustainable conservation of the species can only be achieved in collaboration with all stakeholders, particularly farmers. However, in the past, this species was considered a pest, and farmers actively persecuted it, using invasive methods such as trapping and poisoning. In this situation, early monitoring and prevention are the best tools to minimise and mitigate potential conflicts. We developed a risk model to assess the potential for crop damages by ground squirrels, using data from three different locations with agricultural mosaic landscape in the Czech Republic. Our model is based on four parameters: occurrence and density of ground squirrels, migration potential, and type of habitat. The resulting model provides a graphical map of the local potential risk of crop damage. These maps can complement the regular monitoring of the European ground squirrel and its potential effects on agriculture, aiding the implementation of proactive management strategies to prevent conflicts and support the sustainable conservation of the species.

Selecting a suitable perch can offer many benefits for fish–eating birds such as kingfishers. However, factors affecting perch selection in these species remain poorly studied. We studied perch selection in three species of kingfishers inhabiting the Pantanal of Brazil during the dry season: Megaceryle torquata, Chloroceryle amazon, and Chloroceryle americana. First,we determined the habitat use of the three species. We then assessed the perches these kingfishers used based on four ecologically relevant traits: (1) artificial or natural, (2) perch height, (3) distance to the water, and (4) plant cover. We hypothesized that artificial perches could be more likely selected as they may offer better visibility to fish. We used a resource selection function (RSF), in a case/control design, solving it by model selection of six conditional logistic regression competing models. The probability of presence was independent of the artificial origin of a perch for the three species. It was also independent of the other studied variables, except for individuals of C. amazona, which selected higher perches. We conclude that artificial perches do not influence perch selection of the studied kingfishers, which may indicate that these artificial structures are not altering their behavioral choices.

The lowland tapir Tapirus terrestris is the second largest mammal in South America. It occupies a wide variety of ecosystems where it fulfills key functional roles. It is mainly folivorous, supplementing its diet with fruits, insects, and aquatic invertebrates. The lowland tapir is considered fundamental in shaping forest undergrowth and in seed dispersal processes. Despite its functional importance, ecological aspects related to diet, habitat use, and food preferences are still unknown in much of its geographic range. Currently, these aspects in the Colombian Orinoquia are unknown. We wanted to develop an approximation to the diet of the lowland tapir in the Colombian Orinoquia based on analysis of fecal samples and traditional knowledge derived from citizen science monitoring. Fecal samples were collected between October 2015 and July 2018 and vegetation monitoring and interviews with local communities were implemented. We recorded a total of 37 species of plants, 23 species of which were determined through traditional knowledge. The most representative species in fecal samples were Rudgea crassiloba, Attalea butyracea, Inga alba and Cecropia peltata. The plants most commonly recognized by local communities were Mauritia flexuosa, A. butyracea, Bellucia grossularioides and I. alba. Our results provide insight into the importance of tapirs in the consumption of large seeds such as M. flexuosa and A. butyracea that are considered of economic relevance for local communities. Incorporating citizen science monitoring allowed us to identify plant species that are taxonomically difficult to distinguish and to evaluate new information related to the natural history of cryptic species such as tapirs. This information is crucial to establish conservation strategies for the lowland tapir in the Orinoquia region of Colombia.
低地貘是南美洲第二大哺乳动物。它占据了各种各样的生态系统,在那里它履行着关键的功能角色。它主要以树叶为食,以水果、昆虫和水生无脊椎动物作为补充。低地貘被认为是形成森林灌木丛和种子传播过程的基础。尽管它的功能很重要,但在其地理范围内,与饮食、栖息地利用和食物偏好有关的生态方面仍然未知。目前,这些方面在哥伦比亚奥里诺奎亚是未知的。我们希望根据对粪便样本的分析和来自公民科学监测的传统知识,开发出哥伦比亚奥里诺奎亚低地貘饮食的近似方法。在2015年10月至2018年7月期间收集了粪便样本,并对当地社区进行了植被监测和访谈。我们共记录了37种植物,其中23种是通过传统知识确定的。粪样中最具代表性的种为大黄Rudgea crassiloba, Attalea butyracea, Inga alba和Cecropia peltata。当地群落最常认识的植物是毛蕊花、丁酸草、大花白顶花和白顶花。我们的研究结果深入了解了貘在消费大型种子(如M. flexuosa和A. butyracea)中的重要性,这些种子被认为与当地社区的经济相关。结合公民科学监测使我们能够识别在分类学上难以区分的植物物种,并评估与貘等神秘物种的自然史相关的新信息。这一信息对于制定保护哥伦比亚奥里诺基亚地区低地貘的策略至关重要。

Common names of species matter in species management. However, taxonomic inertia and a blurred perception of a species can hinder the updating of framework documents and conservation schemes. Ibexes from Asia are a notable case of a polytypic species with numerous common names. This review examines data on the common names and taxonomy used for this superspecies. Some taxonomic units and common names are more consistent with recent genetic data than others and highlight management and/or conservation issues. The standardized use of this information in management schemes for the Capra sibirica complex will help lessen the risk of the extinction of distinguishable ibex conservation units from Asia, and, indirectly, of other species that share their geographical ranges.

Intra– and inter–specific phylogenetic relationships and the taxonomic status of pine vole populations have been controversial for years, and cryptic species are thought to exist, especially concering the species' distribution area. To clarify the taxonomic status of Turkish populations we analysed mitochondrial (cytochrome–b and cytochrome oxidase–I) and nuclear (interphotoreceptor retinoid binding protein) gene markers, adding GenBank data from Europe and Caucasia. Considering the data obtained based on mean genetic distance, genetic diversity and fixation index values, Bayesian trees and Median–joining networks, we found that M. subterraneus and M. majori are valid species which have diverged since 1.28 Mya. Findings also suggested that although Anatolian, Thracian (Turkish Thrace and Greece) and European populations of M. subterraneus and Anatolian and Caucasian populations of M. majori have been in the process of divergency since 0.528–0.337 Mya correspond to the Pleistocene glacial periods, these intrapopulations do not appear to be different species.Besides, considering the high intraspecific variation in M. subterraneus, it remains likely that new species could be identified in future studies.

Use of large caliber repeating rifles makes large birds and mammals vulnerable to overharvest or simply mass destruction. This lesson was unscored when unregulated use of firearms caused the local extinction of nearly every species of large mammal and bird in the southeastern United States by the beginning of the twentieth century. During the same period in southern India, restricted access to firearms and a culture of respect for wildlife allowed large mammals and birds to co–exist with a large human population. The survival of megafauna rests on the will of a society to stop uncontrolled killing.

Pelobates cultripes can be considered among those amphibians most affected by climate change in Spain. Its long larval period and predicted shorter pond hydroperiods in its temporary breeding ponds may ultimately reduce population recruitment. We conducted surveys during its breeding season 2021–2022 in order to analyse one of the last remaining urban populations in its southern limit (coastal Malaga province). We recorded a decrease in rainfall and an increase in temperature compared to previous years. Although the species shortened its larval period in comparison with that previously reported, no post–metamorphic juveniles were observed. This interruption in reproduc tion highlights the need for improved monitoring of these isolated amphibian populations as it could be an early warning sign of global changes in the Mediterranean region.

In the present study, we characterized species of bacteria and fungi across a frog community in a seasonal tropical environment in the Natural Protected Area (NPA) Las Musas, Guanajuato, Mexico, using morphological and biochemical protocols. Our three main objectives were to: i) identify the species of microorganisms present in the frog community, ii) determine microorganism prevalence and how it changes throughout the year, and iii) detect diseases and injuries caused by pathogens (bacteria and fungi). Across 150 anurans analyzed, seven species of anurans especies (Anaxyrus compactilis, Incilius occidentalis, Dryophytes arenicolor, D. eximius, Hypopachus variolosus, Lithobates neovolcanicus y Spea multiplicata) hosted at least four genera of pathogenic fungi (Penicillium, Rhizopus, Aspergillus y Batrachochytrium) and two genera of pathogenic bacteria (Aeromonas hydrophila and Pseudomonas sp.). We found the prevalence of positive cases was higher in autumn (0.51) than in summer (0.125). Lesions such as peeling of the skin on the belly and swelling of the extremities (red leg) were observed in four of the seven species. This study confirms the presence of bacterial and fungal pathogenic agents in this frog community, and serves as a precedent for future work on monitoring the state of amphibian population health in Guanajuato. It also provides support for the implementation of conservation strategies for this group of vertebrates.

Across 150 anurans analyzed, seven species of anurans especies (Anaxyrus compactilis, Incilius occidentalis, Dryophytes arenicolor, D. eximius, Hypopachus variolosus, Lithobates neovolcanicus y Spea multiplicata) hosted at least four genera of pathogenic fungi (Penicillium, Rhizopus, Aspergillus y Batrachochytrium) and two genera of pathogenic bacteria (Aeromonas hydrophila and Pseudomonas sp.). We found the prevalence of positive cases was higher in autumn (0.51) than in summer (0.125). Lesions such as peeling of the skin on the belly and swelling of the extremities (red leg) were observed in four of the seven species. This study confirms the presence of bacterial and fungal pathogenic agents in this frog community, and serves as a precedent for future work on monitoring the state of amphibian population health in Guanajuato. It also provides support for the implementation of conservation strategies for this group of vertebrates.","PeriodicalId":49107,"journal":{"name":"Animal Biodiversity and Conservation","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43985757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
