Plasticity in the honeybee brain has been studied using the appetitive olfactory conditioning of the proboscis extension reflex, in which a bee learns the association between an odor and a sucrose reward.

Background Understanding how species diversify is a long-standing question in biology. The allopatric speciation model is a classic hypothesis to explain the speciation process. This model supposes that there is no gene flow during the divergence process

Colour polymorphism and conspicuousness do not increase speciation rates in Lacertids
Conspicuous body colours and colour polymorphism have been hypothesized to increase rates of speciation. Conspicuous colours are evolutionary labile, and often involved in intraspecific sexual signalling and thus may provide a raw material from which ...

The sibling species An. coluzzii and An. gambiae s.s. are major malaria vectors thought to be undergoing sympatric speciation with gene flow. In the absence of intrinsic post-zygotic isolation between the two taxa, speciation is thought possible through ...

Mate Choice Drives Evolutionary Stability in a Hybrid Complex. [PDF]
Previous studies have shown that assortative mating acts as a driver of speciation by countering hybridization between two populations of the same species (pre-zygotic isolation) or through mate choice among the hybrids (hybrid speciation).

SPECIATION AND MACROEVOLUTION [PDF]
Species and higher taxa represent, phenomenologically, two very different levels in the hierarchical organization of the living world. Ever since there has been a concept of evolution, there has been the problem how one can get from the species level to that of the higher categories.

Origin and diversification of Lake Ohrids endemic acroloxid limpets: the role of geography and ecology [PDF]
Background: Ancient Lake Ohrid, located on the Albania-Macedonia border, is the most biodiverse freshwater lake in Europe. However, the processes that gave rise to its extraordinary endemic biodiversity, particularly in the species-rich gastropods, are ...
