Due to the country’s social challenges and the difficult access to the Doña Juana – Cascabel National Natural Park the biological knowledge concerning groups such as mammals, is based on studies prior to the park’s declaration, reports from park rangers and residents. Between October 2017 and February 2018, eight trail cameras were set up in the Doña Juana – Cascabel National Natural Park and its buffer zone. We reviewed the information captured in these cameras and identified eight mammal species, three of which are new reports for the park. In total, 24 species were reported, including charismatic Andean species such as the spectacled bear (Tremarctos ornatus), and the Andean tapir (Tapirus pinchaque). The mammal diversity documented for the park is low (24 species) compared to other Andean areas. Further field work is necessary to complete the species inventories. Nevertheless, this research, to our knowledge is the first effort to study the medium and large mammals of the Doña Juana – Cascabel National Natural Park since its establishment in 2008.","PeriodicalId":49892,"journal":{"name":"Mammalia","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140074937","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}

Pangolins (Order: Pholidota) are a threatened group of mammals that are challenging to monitor across their range. In this study, we assessed the use of arboreal and ground camera traps for monitoring the three pangolin species native to West Africa in the Ziama Man and Biosphere Reserve, Guinea. We fit occupancy models to our data to examine the effect of factors related to camera height and tree height on detection probability. In addition, we evaluated the utility of deploying multiple cameras within the same tree. Our study showed that arboreal camera traps can successfully detect both arboreal pangolin species, with the highest detection in mid-canopy for white-bellied pangolin and mid-to high-canopy for black-bellied pangolins. In addition, our results suggest at least 4–6 cameras deployed on each tree to maximize the opportunity of detecting these species. We did not detect giant pangolins. Further studies are needed to continue improving detection of all three pangolins for monitoring and adaptive management of these heavily harvested and traded species.","PeriodicalId":49892,"journal":{"name":"Mammalia","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139645567","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}

Here we provide novel information about litter size, birth timings, courtship and multi-generational groups in a population in the Chingaza massif in Colombia. Pregnant females, mothers with cubs, estimated birth times, and litter size were registered through camera trapping of a population at the Chingaza massif (Colombia) between 2011 and 2016. A total of 34 independent records of reproductive female bears were obtained. Twenty-eight (28) different reproductive females were recognized by external key features. Six different females were recorded only pregnant, two others were recorded pregnant and later with cubs, and 20 others were recorded only with cubs. In total, 29 cubs were recorded in 22 litters, with a mean litter size of 1.27 (SD = 0.45): 16 litters with one cub, 5 with 2 cubs, and 1 with 2 cubs + a big cub from a previous litter (>1 year). The highest records of mothers with little cubs were obtained for the low rain season in December, January, and February, full of dry-season-fruiting Ericaceae shrubs. Likewise, the highest estimated births were obtained during the rainy time in June. Multi-generational groups and the courtship behaviors are reported for the first time in Colombia.","PeriodicalId":49892,"journal":{"name":"Mammalia","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139482757","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 this study, the presence of fluctuating asymmetry of four anatomical structures of the arboreal rodent Rhipidomys mastacalis was evaluated using geometric morphometrics. The study focused on adult specimens collected in a mosaic of vegetation composed of forested vegetation, occupancy mosaics in forested areas, and cocoa plantations. The results showed significant values of fluctuating asymmetries in all structures and in all areas. The skulls and scapulae showed the highest values of asymmetry in forested vegetation and cocoa plantations, while the mandibles showed the greatest values in forested vegetation, and the pelvis in occupancy mosaics and cocoa plantations. These findings are consistent with previous studies that have evaluated developmental stability in mammals and suggest that high asymmetry values indicate an effect on different phases of ontogeny, which can harm the survival of a species in future generations. Overall, this study provides important insights into the impacts of habitat fragmentation on Rhipidomys mastacalis and highlights the need for conservation efforts to preserve the integrity of the Brazilian Atlantic Forest and its diverse range of wildlife.","PeriodicalId":49892,"journal":{"name":"Mammalia","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139482755","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}
