The ability to accurately estimate bee mass through measurements of intertegular distance (ITD) is an important tool for field biologists. ITD is the distance between the bases of the 2 wing tegulae on the bee’s thorax. However, the relationship between ITD and bee mass can vary based on species and sampling region. A collection of 92 bees—representing 3 species—was examined to assess the accuracy of ITD in estimating dry mass for bees in northwest Ohio. The focus was on 3 species: silky striped sweat bees (Agapostemon sericeus), honey bees (Apis mellifera), and common eastern bumble bees (Bombus impatiens). Overall, there …

The drive for animals to regulate their water content can have significant consequences for food webs in xeric ecosystems. But the importance of animal water balance (gains vs losses) for mesic food webs has not been explored. Impervious surfaces in cities absorb and re-radiate solar radiation, raising local temperatures. Higher temperatures lead to greater rates of organismal water loss. Thus, urbanization of mesic regions may lead to greater likelihood of desiccation, with consequences for food webs. We tested the effects of animal water balance on a mesic urban food web by supplementing animal-available water (but not plant) within trees in …
