In 2022, two events of fishing cats reaching nests with fledglings were documented. In one event, the cat killed four fledglings. The species primarily follows a piscivorous diet and is evolutionarily adapted for semi-aquatic hunting niches. These records provide the first known evidence of the arboreal hunting behaviour observed in the fishing cat.","PeriodicalId":49892,"journal":{"name":"Mammalia","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139437491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We studied immunological condition and physiological stress in the common vole and how it varied with environmental factors linked with population fluctuations, namely flea and <jats:italic>Francisella tularensis</jats:italic> (the bacterium causing tularemia) prevalence. We used two leukocyte indices, neutrophil-to-lymphocyte ratio (N:L) and proportion of eosinophils, as physiological long-term stress indicators, and measured levels of immunoglobulins (Ig) as a generic index of immunological condition. Leukocyte indices showed a hump-shaped relationship with Ig levels, consistent with an interdependence between physiological stress and immunological condition. N:L was negatively associated with vole density only in males. Eosinophil proportion was explained by the interaction between flea burden and tularemia prevalence, with highest levels in flea-infested voles also infected with tularemia. Ig levels did not vary with sex or flea prevalence but increased in tularemia-infected voles. When Ig levels were included as covariates in our models, the associations between leukocyte indices and environmental factors remained significant. Results suggest sex-specific associations between physiological stress and population density, and an influence of tularemia infection depending on ectoparasite load. We recommend using immunological parameters complementarily to leukocyte indices when studying physiological stress and infection dynamics in wild populations.","PeriodicalId":49892,"journal":{"name":"Mammalia","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139083029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spotted hyaenas (<jats:italic>Crocuta crocuta</jats:italic>) are important members of the African large carnivore guild but, like other members of the guild, routinely come into conflict with people because of their large home ranges that are not always confined to protected areas. To effectively conserve spotted hyaena populations, it is paramount to monitor their abundance through reliable and cost-effective techniques. We estimated the density of spotted hyaenas in Hluhluwe–iMfolozi Park (HiP), South Africa using camera trap images and a spatially explicit capture-recapture (SECR) framework between 2013 and 2018. We estimated an average of 18.29 ± 3.27 spotted hyaenas per 100 km<jats:sup>2</jats:sup> between 2013 and 2018, with an annual estimated high of 20.83/100 km<jats:sup>2</jats:sup> in 2014 and a low of 11.98/100 km<jats:sup>2</jats:sup> in 2015. Our results demonstrate that camera trap by-catch data can be used for estimating spotted hyaena densities over time. We believe that given the widespread use and deployment of camera traps across Africa, collaborative efforts to use existing data to improve regional and continental estimates and population trends for spotted hyaenas should be a priority.","PeriodicalId":49892,"journal":{"name":"Mammalia","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139062274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
