Insect populations including butterflies are declining worldwide, and they are becoming an
urgent conservation priority in many regions. Understanding which butterfly species migrate …

Ecology concerns itself with explaining such things as why species live where they do, why
they exist at certain densities, why they do or do not persist in a given habitat, why certain …

Gene dispersal (flow, or migration) within and between plant populations has been of
continuous interest to plant breeders and seed producers for many decades. Economic …

Frequency‐dependent selection on warning color can maintain narrow hybrid zones
between unpalatable prey taxa. To measure such selection, we transferred marked …

Animal-plant mutualisms have been extensively described and yet, to date, we have no
clear understanding of the general ecological and evolutionary importance of such …

A protected and warningly coloured butterfly can become a muellerian mimic of another
species in two steps:(i) a major mutation converts the pattern of the less protected species to …

The social systems of New World species of jays are compared behaviorally and
ecologically. Two lines leading to sociality are identified, one connecting the pair-in-territory …

The Heliconius butterflies are one of the classic systems in evolutionary biology and have
contributed hugely to our understanding of evolution over the last 150 years. Their dramatic …

The natural color pattern of individuals of the unpalatable and mimetic butterfly Heliconius
erato was altered to a unique nonmimetic pattern. When returned to natural populations, the …

The neoDarwinian theory of evolution (or" modem synthesis") may not explain evolution in
the long term. In particular, it has been suggested that it explains neither the discontinuities …
