Rudolf Sachs,Rudolf E. Kamphausens. Fragment area reductions negatively affected aboveground processes such as herbivory and parasitoidism, whereas leaf litter decomposition and most network parameters were not affected. Edge effects were variable, favoring some insect groups (i.e., ground-dwelling arthropods and parasitoids) and p

Of all species, 10% are likely to be affected by these threats to a moderate degree or not at all. By 2050, 84%, and 16% of species are expected to decreas

A further section then follows to discuss the mechanical basis of active hearing, whereby energy is added to the hearing system to condition its acoustic response, again using available examples. Finally, the chapter concludes with a discussion on the current state-of-the-art in this acti
