Competition is considered an important force in structuring plant communities and in governing
niche relations, but communities recovering from disturbance, may be less governed by …

Urbanization is a global phenomenon with major effects on species, the structure of community
functional traits and ecological interactions. Body size is a key species trait linked to …

The sweat bees (Family Halictidae) are a socially diverse taxon in which eusociality has
arisen independently numerous times. The obligate, primitively eusocial Lasioglossum …

Understanding population genetic structure is key to developing predictions about species
susceptibility to environmental change, such as habitat fragmentation and climate change. It …

Orchid bees (Hymenoptera, Apidae, Euglossini) are important pollinators of many plant families
in Neotropical forests, habitats that have become increasingly degraded and fragmented …

The origin of eusociality is often regarded as a change of macroevolutionary proportions [1,
2]. Its hallmark is a reproductive division of labor between the members of a society: some …

Urbanization is considered a global threat to biodiversity; the growth of cities results in an
increase in impervious surfaces, soil and air pollution, fragmentation of natural vegetation and …

Although avocado is native to Mexico, there are no comparative measures in this country on
the performance of its flower visitors as pollinators. The contribution of honey bees, flies and …

There is concern about the worldwide decline of bees, in which genetic factors may play a
role. As populations of these haplodiploid insects suffer habitat fragmentation and subsequent …

As a result of habitat loss and a number of additional potential causes, populations of both
managed and unmanaged bees have been reported to be declining during at least the last …
