Morphological traits can be highly variable over time in a particular geographical area.
Different selective pressures shape those traits, which is crucial in evolutionary biology …

Under natural selection, wing shape is expected to evolve to optimize flight performance.
However, other selective factors besides flight performance may influence wing shape. One …

Current global change substantially threatens pollinators, which directly impacts the
pollination services underpinning the stability, structure and functioning of ecosystems …

Background Sex-limited polymorphisms have long intrigued evolutionary biologists and
have been the subject of long-standing debates. The coexistence of multiple male and/or …

In order to quantify shape variation, many powerful, free, easy-to-use and dedicated
software packages have been developed that quickly digitize and/or analyse landmark data …

Odontocete mandibles serve multiple functions, including feeding and hearing. We consider
that these two major functions have their primary influence in different parts of the …

Contemporary theory predicts that the degree of mimetic similarity of mimics towards their
model should increase as the mimic/model ratio increases. Thus, when the mimic/model …

Among other human-related activities, habitat loss and fragmentation are currently ranked
as the most important environmental features affecting the persistence of animal and plant …

Accurate data on dispersal ability are vital to the understanding of how species are affected
by fragmented landscapes. However, three factors may limit the ability of field studies to …

Wing shape has been shown in a variety of species to be influenced by natural and sexual
selection. In damselflies, front-and hind wings can beat independently, and functional …
