Dense exotic conifer plantations are replacing the steppe in Argentinean northern Patagonia. This study aimed to evaluate the effect of conifer afforestation on the occurrence and food availability in a Z. pichiy population in north-western Patagonia. Fifteen sites in the native steppe and 50 in exotic pine plantations were sampled. We recorded the number of signs of pichi’s presence and the diversity of invertebrates. Signs of Z. pichiy presence decreased in pine afforestation compared to the native steppe. Additionally, we found a decrease in the abundance, richness, diversity, and biomass of arthropods in pine plantations. Therefore, the presence of pine plantations in the steppe reduces the main food items of Z. pichiy and also eliminates the native steppe vegetation structure that provides preferred places to dig burrows. Pine monocultures do not provide a suitable habitat for Z. pichiy and may exacerbate the degradation of an already disturbed environment.","PeriodicalId":49892,"journal":{"name":"Mammalia","volume":"168 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141782279","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}

This study unveils the first insights into the ecology of the Eurasian red squirrel (Sciurus vulgaris) in Mongolia, and specifically in Bogd Khan Mountain Strictly Protected Area. We used by-catch data obtained from camera traps to analyze activity patterns and potential interactions with mammalian predators. Red squirrels exhibited primarily diurnal activity with occasional nocturnal forays, while potential predators like foxes (Vulpes vulpes, Vulpes corsac) and martens (Martes foina, Martes zibellina) displayed cathemeral and nocturnal patterns, respectively. The diurnal Pallas’s cat (Otocolobus manul) showed the greatest activity overlap with squirrels. Suggesting predator avoidance behavior potentially mediated by olfactory cues, squirrel activity was negatively impacted by marten presence, which was in turn potentially affected by human disturbance. We highlight the need for further investigations, particularly regarding the dietary composition of Pallas’s cats in forested habitats and the broader ecological implications of human disturbance on predator–prey dynamics within this crucial conservation area.","PeriodicalId":49892,"journal":{"name":"Mammalia","volume":"45 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141738280","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}

In Switzerland, primarily inhabiting mountain forests, they have recently started to expand into human-dominated lowland landscapes. To study their habitat selection, we analyzed day- and nighttime positions of 15 GPS-collared red deer. Our results show that during daytime, all animals generally preferred forests; open land was mainly used at night. In summer and fall, some lowland individuals deviated from this pattern and used agricultural crops as daytime retreats. Human settlements were often avoided in the lowlands. Day-site selection in the lowlands occurred irrespective of the distance to trails and the probability of being accessed by humans, in contrast to the pattern observed in the mountains. At night, red deer preferred forest edges and open land. In the lowlands, human settlements were avoided. Trails and transport infrastructures had a marginal influence at night. Our study confirmed a high behavioral plasticity of red deer. The use of daytime retreats close to trails and in high-standing crops represent major extensions of their behavior. Our habitat models indicate that there is ample suitable habitat in the lowlands, which is of major relevance for their management.","PeriodicalId":49892,"journal":{"name":"Mammalia","volume":"25 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141738281","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}

However, some carnivore species can exploit abundant food sources in human-dominated landscapes. In this study, we investigated the diet of a specialist carnivore, the serval (Leptailurus serval), inhabiting artificial and natural landscapes surrounding a petrochemical plant in the Highveld of Mpumalanga, South Africa. From 2013 to 2018, for each year, we collected and analysed a total of 264 scat samples. We found that rodent species dominated the serval diet, while other prey items like birds, insects, and unidentified prey contributed little to the diet. In terms of biomass consumed, Otomys sp (56.94 %), Mastomys sp (19.12 %), and Rhabdomys sp (8.68 %) were the most important rodent prey. We further found that biomass consumed is only affected by species, not season or species–season interactions. Our results concur with previous studies that serval is primarily a rodent specialist and that specialisation holds even in human-altered landscapes.","PeriodicalId":49892,"journal":{"name":"Mammalia","volume":"34 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141610255","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}

The recent rediscovery of the species provides a rare opportunity to clarify its taxonomy and phylogenetic relationship within the genus Tragulus. In this study, we sequenced the complete mitochondrial cytochrome b gene for samples of T. versicolor and T. kanchil from Vietnam. Our molecular results show that the species forms a distinct evolutionary lineage sister to all other species in the genus, confirming the earlier hypothesis based on morphological evidence. However, further research is needed to assess the genetic diversity of the species and design appropriate conservation measures. As the species has not been secured over much of its range, it is recommended that the population in Nui Chua National Park, the only one covered by a protected area, be prioritized for conservation actions. Conserving the species in this unique and imperiled ecosystem will also benefits a suite of locally endemic and threatened species of fauna and flora.","PeriodicalId":49892,"journal":{"name":"Mammalia","volume":"38 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141528778","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}
