Our findings can have important implications for the species conservation and understanding forest ecological dynamics.","PeriodicalId":49892,"journal":{"name":"Mammalia","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2023-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138515928","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}

Therefore, this article aims to determine which organisms consume those carcasses in an urban reserve. For this, 53 rodent carcasses were placed in front of camera traps to record their consumers. The final destiny of 41 carcasses is known: 76 % were consumed by opossums (<jats:italic>Didelphis virginiana</jats:italic>) and 24 % by ringtails (<jats:italic>Bassariscus astutus</jats:italic>). Flies and ants attempted to take advantage of the carcasses but in all cases ended up losing the competition to mammals. Opossums are the most efficient carrion consumers, as they exhibit learning as to where the carcasses are located and are able to consume old carcasses (up to 10 days old). This suggests that mid-size mammals, especially opossums, are providing an important ecological and health service for both natural ecosystems and human populations by removing rodent carcasses that otherwise could become sources of infection.","PeriodicalId":49892,"journal":{"name":"Mammalia","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2023-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138515919","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 main aim of this paper is to give a descriptive and quantified analysis of the modern wild reindeer morphological diversity. The morphometric variation was quantified, based on 262 adult specimens of both sexes, by both linear measurements, analysed through log shape ratio computed from post-cranial bones and teeth measurements, and landmarks and sliding semi-landmarks based geometric morphometrics (GMM) to quantify molars size and shape. All anatomical parts (teeth, metatarsals, metacarpals) highlighted differences between the continental and insular subspecies. Our main results pointed out morphometrics characteristics of nowadays reindeer subspecies, like differences in proportions between the size of metapodials or lower cheek teeth with the body size, that could be of great interest for archaeozoological research.","PeriodicalId":49892,"journal":{"name":"Mammalia","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2023-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138515940","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}

Although the underlying cause of this rare phenotype is undeterminable from camera trap images, the individual does not display the pink eyes commonly characteristic of albinism. It is surprising that this individual has survived to adulthood, as its bright white colouration makes it more vulnerable to predation, as well as a target for hunters. Further study of this individual could reveal insights into how it has survived, and the genetic health of the local population of T. kanchil .","PeriodicalId":49892,"journal":{"name":"Mammalia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135567884","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}
