Identifying the most appropriate bait for a camera trap study is an important step in sampling design, as some baits may perform better than others in attracting different animal species. In this study, we compare the vertebrate communities detected using five different widely used baits (i.e., fruit, sardines, valerian extract, a mix of sweet fruits and peanut butter, and a combination of valerian extract and sardines). We assess their performance and characterize the species best detected by each bait in the diverse Cerrado biome. We identified a total of 46 species of vertebrates: 15 mammals, 4 reptiles, and 27 birds. The baits differed in their estimates of community composition, richness, and abundance. In general, valerian extract detected fewer individuals and species than any of the other baits. Fruits detected the largest number of bird species. Sardines detected the largest number of species overall and were the best bait for felines and reptiles. Baits of an animal origin performed similarly to those of a plant origin. Our study shows that baits should be selected based on the objective of the study.

我应该使用哪种诱饵?在高度多样化的塞拉多森林中通过相机陷阱研究获得的见解

为相机陷阱研究确定最合适的诱饵是采样设计中的重要一步,因为某些诱饵在吸引不同动物物种方面可能比其他诱饵表现更好。在这项研究中,我们比较了使用五个不同的广泛使用的诱饵(即水果,沙丁鱼,缬草提取物,甜果和花生酱的混合物以及缬草提取物和沙丁鱼的混合物)检测到的脊椎动物群落。我们评估它们的性能,并描述在各种Cerrado中每个诱饵都能最好地发现的物种生物群落。我们确定了总共46种脊椎动物:15种哺乳动物,4种爬行动物和27种鸟类。这些诱饵对社区组成,丰富程度和丰富程度的估计有所不同。通常,缬草提取物检测到的个体和种类少于其他任何诱饵。水果是鸟类数量最多的物种。沙丁鱼总体上检测到种类最多,是猫科动物和爬行动物的最佳诱饵。动物来源的诱饵的表现与植物来源的诱饵相似。我们的研究表明应根据研究目的选择诱饵。
