摘要

白唇虎鲸(WLP)是一种大型哺乳动物,群居生活,需要大面积的保护区才能生存。在过去的几十年里,WLP的分布范围已经缩小,在预计会发生的地区,如Goiás西南部中部地区和巴西中西部地区,已经没有了WLP的分布。因此,本文提出了Goiás州西南部8个新的WLP记录,并提供了类群大小和景观背景的信息。利用相机诱捕法记录wlp,提取其所占景观的原生覆盖度百分比(NC%)、平均欧几里得最近邻距离(MENND)和最大原生斑块面积(LP(公顷))。在人类化景观中,WLP类群大小为1 ~ 52个个体(占NC%的4.6 ~ 30.7%),MENND为89.4 ~ 165 m, LP为48.8 ~ 297.9。这些发现可能表明该物种正在返回使用该地区。然而,我们强调,由于所研究景观的人类化水平,该地区可能无法长期支持可行的WLP种群。

New records of White-lipped Peccaries in altered landscapes of the Brazilian Midwest

New records of White-lipped Peccaries in altered landscapes of the Brazilian Midwest

The White-lipped Peccary (WLP) is a large-sized mammal that lives in groups and needs large, preserved areas to survive. Over the last decades, the distribution area of the WLP has been reduced, being absent from areas where its occurrence is expected, such as the central region of southwestern Goiás, Brazilian Midwest. Therefore, here we presented eight new records of WLP in southwestern of Goiás state, with information on group size and landscape context. WLPs were recorded by camera trap, and we extracted the percentage of native cover (NC%), mean of Euclidean nearest-neighbor distance (MENND), and largest native patch area (LP (hectares)) in the landscape occupied by them. The WLP group size ranged from 1 to 52 individuals in anthropized landscapes (4.6 to 30.7 of NC%), with a MENND range of 89.4 to 165 m and LP ranged from 48.8 to 297.9. These findings could be an indication that the species is returning to use the region. However, we stress that this area may not support viable WLP populations in the long-term due to the level of anthropization of the studied landscape.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
