A comparison of two widely used methods for estimating taxonomic and functional diversities of epigeal arthropods in some temperate grasslands
Résumé
Suction sampling is increasingly being used to estimate abundance and diversity of epigeal arthropods, yet no study has quantified its efficiency simultaneously assess at different taxonomic functional scales. Here, we evaluated the this method (G‐Vac) relative pitfall (Barber) trap, which been for a long time, their possible complementarity. To do that, compared several metrics wide range arthropod taxa, with particular focus on spiders (species level), using traits such as trophic diet, hunting guild, body size. Sampling took place in some coastal grasslands Brittany (France) spatially paired design vacuuming unfenced trapping. In total, 21159 arthropods were identified order or family levels, including 1018 adult species. was more efficient than trapping collecting phytophagous web‐builders, small species living vegetation detritivores, large‐bodied near soil surface. We conclude that short‐term G‐Vac suction interesting obtain ‘snapshot’ patterns richness. However, assessing diversity, are complementary methods.
