Rabbit survey data on creosotebush and grassland routes from the long-term Small Mammal Exclusion Study at Jornada Basin LTER, 1996-ongoing

This data package contains rabbit survey data from grassland and creosote shrubland habitats on Jornada Experimental Range (JER) and Chihuahuan Desert Rangeland Research Center (CDRRC) lands. Two survey routes were established along Jornada Basin roads in 1996; one in black grama grassland and the other in creosotebush shrubland. Quarterly surveys are conducted on these roads at or near the full moon to measure the density of rabbits in the two vegetation types. Each route is about 6 miles long. Parallel studies were established at the Sevilleta LTER site (New Mexico, USA) and Mapimi Biosphere Reserve (Durango, Mexico). Data collection began in April 1996 and includes date and time lagomorphs are spotted, species identification, habitat type, distance/direction from vehicle, and comments on the weather, moon, and anything unusual. This study is ongoing with new data collected quarterly. Resources in this dataset:Resource Title: Website Pointer to html file.

本数据包收录了来自乔恩达实验区（Jornada Experimental Range，简称JER）和奇瓦瓦沙漠放牧研究中心（Chihuahuan Desert Rangeland Research Center，简称CDRRC）草甸和羊茅灌木丛生境的兔类调查数据。1996年，在乔恩达盆地道路上设立了两条调查路线；一条位于黑羊茅草甸，另一条位于羊茅灌木丛。为了测量两种植被类型中兔类的密度，这些道路上的季度调查在满月时或附近进行。每条路线的长度约为6英里。在塞维利亚LTER研究站（美国新墨西哥州）和马皮米生物圈保护区（墨西哥杜兰戈州）设立了平行研究。数据收集始于1996年4月，包括发现兔类的日期和时间、物种鉴定、生境类型、车辆距离/方向以及关于天气、月亮和任何异常情况的注释。该研究正在进行中，并每季度收集新的数据。本数据集包含的资源：资源标题：网站指针至HTML文件。文件名：网页，URL：https://portal.edirepository.org/nis/mapbrowse?scope=knb-lter-jrn&identifier=210086006 网页提供信息并链接至可下载的数据文件。
