This is the only extant species currently known in the genus <i>Scaptonyx</i> (Talpidae), but recent studies have revealed highly diverse lineages within this taxon. However, the broken type specimen and unspecified type locality of this species have hindered comparison between specimens towards a taxonomic evaluation. We reviewed the literature documenting the expeditions of the collector Armand David and narrowed down the type locality of this species to Minshan Mountain, western Sichuan, China. We compared <i>S. fusicauda</i> topotypes with specimens from 2 separated mountain ranges in western Yunnan, China-<i>S. f. affinis</i> Thomas, 1912 from the Baima Mountain and an undescribed species (<i>S.</i> sp. 1) from the Gaoligong Mountains. Specimens from the 3 localities can be distinguished by multiple external, craniomandibular, and dental characteristics. Phylogenies based on mitochondrial and nuclear genes also provided consistent topologies supporting <i>S. fusicauda</i>, <i>S. f. affinis,</i> and <i>S.</i> sp. 1 as distinct monophyletic species. <i>Scaptonyx</i> sp. 1 split from the sister clade (<i>S. fusicauda</i> + <i>S. f. affinis</i>) ca. 19.79 Ma, while <i>S. f. affinis</i> split from <i>S. fusicauda</i> ca. 9.56 Ma.

African leopards (<i>Panthera pardus</i>) are listed as vulnerable, with declining populations. However, population size estimates are rare for much of their range. Here, we provide population size estimates for leopards in the Limpopo (LNP) and Banhine (BNP) national parks and the Lebombo Conservancy (LC), in western Mozambique.

We estimate populations of 87, 15, and 13 leopards in LNP, BNP, and LC, respectively. Population size estimates derived from trophic scaling suggest that leopards are limited by bottom-up prey resources in LNP and LC, but there is evidence for top-down regulation in BNP.

Little population structure has been detected in northwestern North America with microsatellite loci, but low genomic diversity in wolverines may limit detection of genetic differences in this highly vagile species. Here, we genotyped a relatively large sample of wolverines from across Alaska (US) and adjacent Yukon (Canada) with 12 microsatellite loci (<i>n </i>= 501) and 4,222 single nucleotide polymorphisms (SNPs; <i>n</i> = 201) identified using restriction-site associated DNA sequencing. We compared the relative ability of our microsatellite and SNP datasets to evaluate population genetic structure, genetic diversity, differentiation, and isolation by distance (IBD). We predicted that the SNP dataset would detect a higher degree of genetic structure and provide more significant support for IBD. We found evidence for multiple genetic clusters, including genetic distinctiveness of wolverines in southeast Alaska and on the Kenai Peninsula. The SNP dataset detected additional genetic clusters that align largely with ecoregions, and the SNP dataset showed stronger evidence of IBD, while the 2 datasets were generally consistent in estimates of genetic diversity and differentiation among regional groups.

In this study, we tracked 11 fishing cats with satellite GPS collars to investigate their home range size and habitat use in and around Koshi Tappu Wildlife Reserve, Nepal. The minimum convex polygon (MCP) and autocorrelation-informed kernel density estimation (AKDE) were used to estimate home range sizes of the fishing cats. Altogether 2,303 locations were obtained from 11 collared cats. The average home ranges of fishing cats (<i>n</i> = 8) with 95% MCP and 95% AKDE were 29.12 ± SD 16.89 km² and 39.88 ± 26.16 km², respectively.

Sex-specific social organization with a single male overlapping with multiple nonoverlapping adult females was consistent with home range behaviors of other carnivores. The highest number of locations of collared fishing cats were in tall grasslands, whereas they highly preferred wetlands. A large part (over one-third) of fishing cat home ranges covers human-dominated areas such as fishponds, agriculture, and settlements encompassing various threats to fishing cats including persecution, road kills, and dog attacks.

The Brazilian Pantanal feral hog (“porco-monteiro”) evolved after a long-term feralization process and represents a significant proportion of the mammalian biomass in the region. Its coexistence with native fauna brings several ecological impacts, which are mitigated by the Brazilian Pantanal wetland vastness and resource availability. They are a local subsistence game resource but also impact crops and pastures. Around the 2000s to mid-2010s, numerous European wild boar were introduced in Brazil to fulfill a demand for gourmet meat. Wild boar was also introduced to the Brazilian Pantanal as a game species and to breed with porco-monteiro feral hogs in a commercial venture to produce an even more exotic meat. The craze for wild boar meat has since dwindled, but their populations remain widespread and uncontrolled. Moreover, the full impact of the wild boar introduction on feral hog populations is still unknown. This study analyzes the skulls of porco-monteiro feral hogs from the 1990s, 2000s, and 2010s to assess possible morphological and functional variations along with skulls of wild boar and hybrids from Argentina, Uruguay, and Southern Brazil. The results indicate a trend of broadening of feral hog skulls at the coronal plane and a progressive reduction of the semispinalis capitis muscle scars over the decades. Biomechanical analysis denoted a decrease in head-elevation force that could affect the rooting performance of the latest feral hog morphotypes. Taken together, results show that wild boars likely influenced the evolution of the Pantanal feral hog skull. The magnitude of ecomorphological implications of these morphofunctional changes is unknown, as well as its effects in the Brazilian Pantanal wetland ecology.","PeriodicalId":50157,"journal":{"name":"Journal of Mammalogy","volume":"8 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142266817","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}

Among monomorphic mammals, competition for resources and gender-related differences in physiology and reproductive strategies may translate into different activity patterns of males and females. Therefore, to understand the daily activity pattern both aboveground and belowground of the semifossorial rodent Clyomys laticeps, we tested the following hypotheses: (1) males and females differ in their diel activity patterns; (2) males are active for longer periods than females due to a promiscuous mating system and female site fidelity; and (3) higher maximum temperatures restrain C. laticeps activity. The study was carried out in the Serra de Caldas Novas State Park (Goiás, Brazil) in the Cerrado biome. The activity of C. laticeps was recorded using the telemetry technique over 5 days and nights (twice in each season, rainy and dry, between 2019 and 2021). Clyomys laticeps activity was bimodal, with 2 peaks around dawn and dusk, resembling a crepuscular pattern. Temporal segregation in male and female activity patterns was restricted to the dry season, when female activity was more diurnal than males who were mainly nocturnal. Intersexual competition for resources or male-avoidance behavior by females during the dry food scarcity season could contribute to this pattern, although it may also be explained by gender-related differences in thermal tolerances. Overall, males were active for longer periods than females, probably as a strategy to increase mating opportunities among the former and site fidelity in the latter. Finally, temperature imposed major constraints on C. laticeps activities who preferred milder temperatures and avoided being active in temperatures above their thermoneutral zone.","PeriodicalId":50157,"journal":{"name":"Journal of Mammalogy","volume":"28 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142267023","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}
