What is Habitat selection as a major resource partitioning mechanism between the two sympatric sibling bat species Myotis myotis and Myotis blythii about?

1. Ecomorphological studies have described local bat communities as densely‐packed species assemblages arising from non‐deterministic processes. Together with the observation that insectivorous bats readily exploit patchy, often unlimited trophic resources, this has even led to the claim that partitioning of niche space may be absent. However, the paucity of data on resource exploitation __per se__ among bat guilds rarely allows these assertions to be verified. In particular, the mechanisms allowing the co‐existence of similar species have proved difficult to determine. 2. As a subset of an insectivorous guild, the vespertilionid bats __Myotis myotis__ and __M. blythii__ offer an opportunity to examine this question. Genetically closely‐related, they are morphologically almost identical. Yet, as established by faecal analysis, they exploit distinct trophic niches, preying upon ground‐ and grass‐dwelling prey taxa, respectively. The distinct habitat requirements of their basic prey suggest that ecological segregation may stem primarily from a differential allocation of foraging space. 3. The present study tests the hypothesis that sympatric __M. myotis__ and __M. blythii__ segregate
