Abstract – Vertical stratification of animal assemblages has been observed in several arthropod taxa. However,for some groups there is conflicting evidence, such as for the neotropical orchid bees. Here, we used a metaanalysisto evaluate trends in abundance and diversity of euglossine bees across strata. We found no evidence ofstratification in terms of diversity, but abundance

The omnipresence of pathogens makes them a strong selective pressure for most organisms, generating a variety of defensive responses to fight them. One mechanism by which organisms can release this pressure is avoidance of the pathogens in a spatial or temporal context. To date, only a few biological systems provide evidence that habitat selection can
