Quantitative sampling of organisms is often used to provide information in ecological studies, monitor populations, and aid in biodiversity projects. Many studies involve the quantitative sampling of spiders. In this meta-analysis study, 207 peer-reviewed journal articles formed the basis of an initial data set for a quantitative analysis of spider collection techniques. Data collected included country of study, mode of study, trapping techniques used, spider diversity, and number of specimens collected. Our meta-analysis gathered research articles that included 33 different countries of study. Trapping techniques greatly vary depending on the habitat in which spiders dwell. These were divided into aerial, arboreal, terrestrial, and subterrestrial. From the gathered data, 5% of the articles included aerial trapping, 20% included arboreal trapping, 1% included subterrestrial trapping, and 80% included terrestrial trapping. 60% of the terrestrial studies utilized pitfall trapping, 20% used hand collecting, 15% used sweep netting, and 5% used branchbeating.
