Hog Island VA Small-Mammal Trapping 1989-2020

This dataset contains information on long-term small mammal trapping on the Virginia Coast Reserve LTER. Four transects on Hog Island are included in the data, each of which was trapped at least twice each year, typically in the spring and autumn (note: Transect T2 was not trapped every year). Along each transect Sherman Live Traps were placed every 12.5 m along the transect, with an alternating offset of 2.5 m (to remove traps from the path running down the transect). This leaves a total inter-trap distance of 15 m. Traps were baited with peanut butter wrapped in waxed paper and were run sequentially for at least 3 nights in a row. Traps in areas that would experience tidal flooding were placed on styrofoam plastic platforms to provide flotation during high tides. Captured animals were individually tagged with numbered fingerling fish tags placed in the right ear, inspected for sex and sexual characteristics, weighed with a spring scale to the nearest gram and released at the point of capture.本数据集包含弗吉尼亚海岸保护区长期生态研究站（Virginia Coast Reserve LTER）的小型哺乳动物长期诱捕相关信息。数据涵盖霍格岛（Hog Island）上的4条样带，每条样带每年至少开展2次诱捕作业，通常于春季与秋季进行（注：T2样带并非每年均开展诱捕工作）。每条样带沿程每隔12.5米布设谢尔曼活体诱捕笼（Sherman Live Traps），并以2.5米的间距交错布置，以避免诱捕笼遮挡样带通行路径，最终使诱捕笼间的实际间距为15米。诱捕笼以蜡纸包裹的花生酱作为诱饵，连续布设至少3个夜晚开展诱捕。针对易受潮汐淹没区域的诱捕笼，将其安置于发泡聚苯乙烯塑料平台上，以在涨潮时提供浮力。捕获的小型哺乳动物将通过佩戴于右耳的编号幼鱼标签进行标记，同时检测记录其性别与生殖特征，使用弹簧秤称量至最接近1克的精度，并在捕获原地放归。
