Abstract


AQUATIC-TERRESTRIAL CONNECTIVITY: LAKES AS FOOD SOURCES FOR BATS

Emerging aquatic insects constitute an important food resource for terrestrial consumers. Many bat species, for example, feed partly or entirely on aquatic insects. Aquatic insects can also be vectors of pollutants from aquatic to terrestrial organisms. Possible changes in aquatic insect emergence, due to eutrophication or climate change, might have indirect effects on terrestrial consumers. Thus, it is useful to know these aquatic-terrestrial interactions and the dependence of terrestrial animals on aquatic resources. The use of aquatic habitats from bats was reviewed, with emphasis on how anthropogenic impacts on water bodies affect bats. In addition, we conducted a field study of the insect emergence from three temperate lakes of varying trophic status. The seasonal and spatial pattern and fluctuations in the insect emergence, obtained from the three lakes, imply that conservation and monitoring of terrestrial consumers, that use aquatic resources, should consider the seasonality of emerging aquatic insects. Nevertheless, additional large-scale studies are recommended in order to pinpoint the effects that anthropogenic impacts on water bodies have on bats.
