Dispersal of the orchid bee Euglossa imperialis over degraded habitat and intact forest

Conservation Genetics, 2016
Fragmentation of habitat can decrease resource availability and restrict movement among geographic areas. Persistence in fragmented landscapes depends on the maintenance of connectivity among populations, without which genetic diversity may decrease and lead to population declines. Bees are particularly vulnerable to the negative effects of low genetic

Age structure of male Euglossa imperialis (Hymenoptera: Apidae: Euglossini) at nectar and chemical sources in Panama

Journal of Tropical Ecology, 1988
Bees in the tribe Euglossini (Apidae) form an important component of the pollinator fauna in lowland, Neotropical forests (Dressler 1982, Janzen 1971, Williams 1982). The community structure and seasonality of male euglossine bees are relatively well known because they can be attracted to chemical baits (Ackerman 1983a, Dodson et al. 1969, Janzen et al.
