Additionally, we collected more ground beetle species (37 vs. Barrier traps proved to be superior, yielding significantly greater numbers of individuals (n = 3,456 vs. Over three sampling periods we collected 5,186 individuals represented by 43 species. To that end, the effectiveness of two pitfall trap designs (standard trap vs. In order to develop conservation measures for species occupying these habitats a logical first step is to refine sampling methods so that proper biodiversity assessments can be carried out.

Ground beetles are the most well studied inhabitants within these environments where they are often sampled using pitfall traps. 117: 76-82, 2020 | DOI:В 10.14411/eje.2020.008 Barrier pitfall traps increase captures of ground beetles (Coleoptera: Carabidae) on exposed riverine sediments Original article Scott HORN USDA Forest Service, Southern Forestry Sciences Laboratory, 320 Green Street, Athens, GA 30602, USA e-mail: riverine sediments are unique riparian environments that exhibit high biodiversity and harbor many specialist species.
