Abstract

Canopy mammals constitute a diverse and widely distributed group. However, these species have not been widely studied, and there are currently many gaps in our knowledge of their ecology, behaviour, distribution, and conservation status. We identified crucial trends and omissions in terms of research effort on research themes, taxonomic groups, countries, and protected areas (PAs) and geographic information biases. A systematic review was conducted by consulting two electronic databases (Web of Science and Scopus), including research conducted within neotropical countries (from central Mexico to northern Argentina) until the end of the first half of 2021. All the references obtained were reviewed and categorised, and the geographical location of each study was extracted to evaluate geographical gaps. We found that two orders (Carnivora and Didelphimorphia) and three families (Didelphidae, Felidae, and Cricetidae) were the most studied taxa, and were featured in more than 50% of cases. Brazil had the highest number of studies. Topics concerning diseases (19% of cases), distribution (14%), and ecology (14%) were the most frequently addressed; only 4.6% of the studies focused on anthropogenic disturbances, and less than 30% of the studies were conducted within PAs. We found that one of the largest and most important geographical biases in knowledge was in the northern Amazon region, where the number of studies was low or null. This study lays the groundwork for future research on these understudied mammals, to develop better research that can allow us to design more appropriate conservation strategies.

新热带非灵长类树冠哺乳动物:历史趋势、遗漏和地域知识空白
树冠哺乳动物种类繁多,分布广泛。然而,对这些物种的研究并不广泛,目前我们对其生态学、行为学、分布和保护状况的了解还存在许多空白。我们发现了在研究主题、分类群、国家和保护区(PAs)以及地理信息偏差方面的重要研究趋势和遗漏。我们查阅了两个电子数据库(Web of Science 和 Scopus),对截至 2021 年上半年末在新热带国家(从墨西哥中部到阿根廷北部)开展的研究进行了系统性回顾。我们对获得的所有参考文献进行了审查和分类,并提取了每项研究的地理位置,以评估地理差距。我们发现,两个目(食肉目和食肉目)和三个科(食肉目、鼬科和蟋蟀科)是研究最多的类群,占 50%以上。巴西的研究数量最多。涉及疾病(19%)、分布(14%)和生态(14%)的主题最多;只有 4.6% 的研究关注人为干扰,不到 30% 的研究在保护区内进行。我们发现,亚马逊北部地区的研究数量较少或为零,是知识中最大、最重要的地域偏差之一。这项研究为今后研究这些未被充分研究的哺乳动物奠定了基础,以便开展更好的研究,让我们能够设计出更合适的保护策略。

期刊介绍: Mammal Review is the official scientific periodical of the Mammal Society, and covers all aspects of mammalian biology and ecology, including behavioural ecology, biogeography, conservation, ecology, ethology, evolution, genetics, human ecology, management, morphology, and taxonomy. We publish Reviews drawing together information from various sources in the public domain for a new synthesis or analysis of mammalian biology; Predictive Reviews using quantitative models to provide insights into mammalian biology; Perspectives presenting original views on any aspect of mammalian biology; Comments in response to papers published in Mammal Review; and Short Communications describing new findings or methods in mammalian biology.
