A problem for understanding bumblebee biogeography is that if bumblebees dispersed from
Asia through North America to South America, if they are poor at long-distance dispersal …

A detailed phylogeny of bumblebees is urgently needed to understand speciation and
biogeographic diversification in the Neotropical region. We sequenced autosomal and …

Abstract Mexico and Central America are among the most biodiverse regions on Earth,
harboring many species with high levels of interpopulation morphological and genetic …

It is thought that two evolutionary mechanisms gave rise to chromosomal variation in bees:
the first one points to polyploidy as the main cause of chromosomal evolution, while the …

A worldwide decline of many bee species has been reported, but conversely some species
seems to be in expansion. Nonetheless species truly in expansion may be overestimated …

Bumblebees are essential insects for the preservation of biodiversity in many ecosystems,
as they can pollinate a wide variety of wild and cultivated plants. Knowledge of the genetic …

As a consequence of founder effects, small population size and demographic constraints,
island populations are often characterized by low genetic diversity and high inbreeding. The …

Fipronil (FP) is an insecticide used in the treatment and control of pests, but it also adversely
affects bees. Currently, there is no data on the genotoxic effects of FP in the brain of …

Recent improvements in taxonomy consider multiple operational criteria. Integrative
taxonomy provides a methodological framework merging these multisource approaches …

Bumblebees are economically important insects which perform essential pollination tasks in
natural and managed ecosystems. Recent research studying Neotropical bumblebee …
