Thus, effects of pollutant exposure in bats foraging at WWTWs elicit sub-lethal haematological and genotoxic responses which may pose serious long-term risks.
Contrary to the prediction, our observation of foraging behaviors suggest that visual contrasts, especially the luminance contrast, can serve as an important cue in foraging attempts at close range, where fruits would be compared with relatively small number of background leaves and local difference in luminance and blue-yellow values could be used as effective cues.
In small patches, increasing the perceived predation risk caused a decrease in aggression and size variation within groups and an increase in the number of fish foraging at a time, whereas in large patches, increasing the perceived predation risk had no significant effect on aggression, but decreased the number of fish feeding, resulting in an increase in size variation within groups.
Furthermore, recent studies have described spatial distributions of genetic stocks in foraging and developmental areas at-sea based on local and regional ocean current patterns in the Wider Caribbean [28], [37], Atlantic Ocean [40], Mediterranean Sea [45], and Pacific Ocean [46], [47].
Key gaps in our understanding include the role of spatial memory in foraging, how (and at what stage) frugivores make the fine distinctions between fruits of differing nutrient contents that they appear capable of, the role of diet learning through linking post-ingestive feedback to pre-ingestive sensory cues, and the plant traits that influence seed fate during the processing of fruits.

Fraser has noticed from radio-transmitter data that Adélie penguins have been spending more time foraging at sea in recent years.
The Banana Bat, Neoromicia nana specifically exploits the high abundance of chironomid midge prey available at WWTWs but these populations also have higher levels of non-essential metals (Cd, Cr and Ni) in their tissues than bats foraging at unpolluted sites.
