Abstract

Hair tubes are one of the most effective tools for sampling small-mammal assemblages. Despite their efficiency, they can be damaged by wildlife. We quantified wildlife-induced disturbance of hair-tube sampling in the Monte Pisano mountain system in Italy. At each site we tied 2 tubes together to form a hair trap and placed them in 3 different areas. We measured disturbances by counting the number of hair traps disturbed and identified the species that caused damage with cameras. Although approximately 27% (n = 164/600) of hair traps were disturbed, 2 hair traps/site allowed us to collect data from 97% of site checks from undisturbed and retrieved hair traps. Wild boars (Sus scrofa) were attracted to hair traps by olfactory and acoustic signals and caused the most disturbances. Displaced tubes detected a similar number of hairs and number of species as undisturbed tubes; species richness estimates that include retrieved displaced tubes should provide reliable data. To avoid data loss when conducting hair-trap monitoring, we suggest using ≥2 hair traps per site.

野猪对毛管取样的影响

毛管是对小型哺乳动物群采样最有效的工具之一。尽管它们很有效，但也会被野生动物损坏。我们在意大利的皮萨诺山系统量化了野生动物对毛管取样造成的干扰。在每个地点，我们将两根管子绑在一起，形成一个毛管陷阱，并将其放置在 3 个不同的区域。我们通过计算被干扰的毛管数量来测量干扰情况，并用照相机识别造成破坏的物种。虽然约有 27% 的毛陷阱（n = 164/600）受到干扰，但 2 个毛陷阱/站点使我们能够从 97% 的站点检查中收集到未受干扰和已收回毛陷阱的数据。野猪（Sus scrofa）被嗅觉和声音信号吸引到毛发诱捕器上，造成的干扰最多。移位管探测到的毛发数量和物种数量与未受干扰的管子相似；包括收回的移位管在内的物种丰富度估计应能提供可靠的数据。在进行毛发诱捕器监测时，为避免数据丢失，我们建议每个地点使用≥2个毛发诱捕器。

期刊介绍： The Journal of Wildlife Management publishes manuscripts containing information from original research that contributes to basic wildlife science. Suitable topics include investigations into the biology and ecology of wildlife and their habitats that has direct or indirect implications for wildlife management and conservation. This includes basic information on wildlife habitat use, reproduction, genetics, demographics, viability, predator-prey relationships, space-use, movements, behavior, and physiology; but within the context of contemporary management and conservation issues such that the knowledge may ultimately be useful to wildlife practitioners. Also considered are theoretical and conceptual aspects of wildlife science, including development of new approaches to quantitative analyses, modeling of wildlife populations and habitats, and other topics that are germane to advancing wildlife science. Limited reviews or meta analyses will be considered if they provide a meaningful new synthesis or perspective on an appropriate subject. Direct evaluation of management practices or policies should be sent to the Wildlife Society Bulletin, as should papers reporting new tools or techniques. However, papers that report new tools or techniques, or effects of management practices, within the context of a broader study investigating basic wildlife biology and ecology will be considered by The Journal of Wildlife Management. Book reviews of relevant topics in basic wildlife research and biology.
