Cascading effects of grazing intensity on predatory arthropod and parasitoid densities

open access: yesEcological Entomology, EarlyView.
The impacts of grazing on different taxa may also be indirect, depending upon trophic interactions with other members of the community. We studied the effects of grazing by ungulates on pompilid wasps (Hemipepsis and Pepsis hawk wasps) and tarantulas (Aphonopelma hentzi) by comparing the cover of forbs and the densities of hawk wasps and of tarantula ...

Prey Capture Outside of the Web? Observational Evidence of a Novel Form of Prey Capture in a Cave Orb Web Spider

open access: yesEthology, EarlyView.
It is currently not known how the European cave orb spider Meta menardi (d) catches the non‐flying prey, which makes up approximately half of its diet. Our observations in winter and summer from caves in the United Kingdom offer support to the radius tripwire hypothesis (a) over the off‐web hunting hypothesis (b) and the prey slip hypothesis (c ...

Lionfish (Pterois volitans) Show Social Attraction to Conspecifics When Selecting Shelters

open access: yesEthology, EarlyView.
ABSTRACT Group formation in animals can arise from two primary mechanisms: individuals aggregating over resources, or individuals socially benefiting from interacting with conspecifics. Distinguishing between these mechanisms allows us to infer the drivers of group formation, which is of considerable importance for informing management strategies of ...
