Major biogeographic and taxonomic biases are recurrent in biological surveys, including fragmentation studies. Detecting biases and subsequent gaps is crucial to steer future research and suitable conservation policies. We evaluated biogeographic and fragmentation-related biases on antbirds and non-flying small mammals in Brazil, two oversampled and vulnerable taxonomic groups, by surveying papers in the Scielo and the Web of Science. We found 566 articles published from 1945 to 2018, including 55 and 43 fragmentation studies for antbirds and small mammals, respectively. Considering the species richness for each group across the Brazilian biomes, the number of publications for small mammals tended to disproportionately increase while increasing richness. The Atlantic Forest, the most degraded and densely populated biome, contained the highest number of publications. However, the Amazon included a disproportionately high number of papers considering its low population density. Conversely, non-forest biomes such as the Caatinga, Pampa and Pantanal were mostly overlooked. Our results show that research effort for small mammals and antbirds in Brazil is biogeographically biased. We call future research to consider more studies across non-forest biomes and vast unexplored areas within forest biomes to overcome major knowledge gaps on diversity, distribution and ecology of antbirds and small mammals in Brazil.

巴西对蚁鸟和不会飞的小型哺乳动物的生物地理学和碎片化相关研究偏见

主要的生物地理和分类偏差在生物调查中经常出现,包括碎片化研究。发现偏见和随后的差距对于指导未来的研究和适当的保护政策至关重要。我们通过调查 Scielo 和 Web of Science 上的论文,评估了巴西对蚁鸟和不会飞的小型哺乳动物(这两个过度采样且易受攻击的分类群)的生物地理和碎片相关的偏见。我们发现了 1945 年至 2018 年发表的 566 篇文章,其中分别包括 55 篇和 43 篇针对蚁鸟和小型哺乳动物的碎片化研究。考虑到巴西生物群落中每个群体的物种丰富度,小型哺乳动物的出版物数量往往在增加丰富度的同时不成比例地增加。大西洋森林,最退化和人口最稠密的生物群落,包含最多的出版物。然而,考虑到其人口密度低,亚马逊收录的论文数量异常多。相反,卡廷加、潘帕和潘塔纳尔等非森林生物群落大多被忽视。我们的研究结果表明,巴西对小型哺乳动物和蚁鸟的研究工作存在生物地理偏差。我们呼吁未来的研究考虑对非森林生物群落和森林生物群落中广阔的未开发区域进行更多研究,以克服巴西蚁鸟和小型哺乳动物的多样性、分布和生态学方面的主要知识差距。我们的研究结果表明,巴西对小型哺乳动物和蚁鸟的研究工作存在生物地理偏差。我们呼吁未来的研究考虑对非森林生物群落和森林生物群落中广阔的未开发区域进行更多研究,以克服巴西蚁鸟和小型哺乳动物的多样性、分布和生态学方面的主要知识差距。我们的研究结果表明,巴西对小型哺乳动物和蚁鸟的研究工作存在生物地理偏差。我们呼吁未来的研究考虑对非森林生物群落和森林生物群落中广阔的未开发区域进行更多研究,以克服巴西蚁鸟和小型哺乳动物的多样性、分布和生态学方面的主要知识差距。
