Salman, I.N.A., Ferrante, M., Möller, D.M., Gavish-Regev, E. & Lubin, Y. (2020) Trunk refugia: a simple, inexpensive method for sampling tree trunk arthropods.
Journal of Insect Science, 20(2), 1-6. DOI:10.1093/jisesa/ieaa012 (IF2020 1,857; Q2 Entomology)Trees host a large share of the global arthropod diversity. Several methodologies have been described to sample arthropods from trees, ranging from active sampling techniques (e.g., visual searching, beating, or shaking the branches) to passive sampling devices. The majority of these collection techniques are destructive, and do not specifically target the tree trunk arthropod fauna. Here, we describe an alternative sampling method called trunk refugia (TR). TR are cylindrical shelters made of corrugated cardboard that can be secured to trees using string, and can remain exposed for varying time periods. These refugia are inexpensive, easy to use, and suitable to monitor a diverse array of insects and arachnids. Moreover, TR are nonlethal sampling tools, and allow collecting live individuals for behavioral studies or for rearing.
