Ecology and evolution of extravagant feather ornaments
Despite only a fraction of all organisms having evolved extravagant secondary sexual characters, these have played an important conceptual, theoretical and empirical role in evolutionary biology (Darwin, 1871; Cronin, 1991; Andersson, 1994). Secondary sexual characters such as the antlers of deer and the train of the blue peacock Pavo cristatus are presumed to have arisen and be maintained as a...
متن کاملMoult speed affects structural feather ornaments in the blue tit.
Growing evidence suggests that structural feather colours honestly reflect individual quality or body condition but, contrary to pigment-based colours, it is not clear what mechanism links condition to reflectance in structural feather colours. We experimentally accelerated the moult speed of a group of blue tits (Cyanistes caeruleus) by exposing them to a rapidly decreasing photoperiod and com...

15 صفحه اولThe allometric pattern of sexually size dimorphic feather ornaments and factors affecting allometry.
The static allometry of secondary sexual characters is currently subject to debate. While some studies suggest an almost universal positive allometry for such traits, but isometry or negative allometry for nonornamental traits, other studies maintain that any kind of allometric pattern is possible. Therefore, we investigated the allometry of sexually size dimorphic feather ornaments in 67 speci...
متن کاملEcology and Evolution Retreat
09:20 Christopher Noto and Ari Grossman Using functional morphology to compare dinosaur ecological diversity Studies of ecological diversity seek to quantify functional groups to understand community structure. Fossil communities represent a special challenge because direct measurement of the once living ecosystem is impossible, and we must rely on indirect methods to infer ecology. Fortunately...
