Predation risk and state-dependent foraging in scorpions: effects of moonlight on foraging in the scorpion Buthus occitanus
Article Abstract:
Environmental factors such as illumination and humidity influence scorpion (Buthus occitanus) foraging behavior of evaluating food availability and levels of predation risk. A study of scorpion foraging behavior in moonlight show that adult scorpions forage in full moonlight less often than juvenile scorpions. Those adults that are active in moonlit nights show lower mass-to-size ratios than those of scorpions foraging in dark. The results are discussed in terms of state-dependent foraging and relative energy state of scorpions.

Interruptions to foraging and learning in a changing environment
Article Abstract:
A study was conducted to investigate the effects of interruptions, distractions and the dynamic environment on foraging. Results indicate that constant interruptions hinder the acquisition of accurate information. Hence, a forager faced with two options may not achieve the one with the highest current payoff because of the lack of information. The study also discovered that foragers are better off taking an unknown option when the probability for interruption is low.

How long should a dive last? A simple model of foraging decisions by breath-holding divers in a patchy environment
Article Abstract:
Research is presented concerning the diving behavior of seals. The time which is spent underwater searching for food within a patchy environment by seals is discussed. The habits of deep- and shallow-diving species are compared.
