organ systems involved in the processing and storage of energy (e.g. alimentary tract, liver, fat stores) whereas males would benefit from the enlargement of systems important for mate-searching, male–male combat and sperm competition (e.g. larger mass of skeletal muscles, tail, and kidneys)...

Compared with Phloeomys, the two species of Canariomys have experienced a different situation by evolving during a shorter time, without any mammalian competitor, along with an herbivorous giant lizard. No snake occurs in the Canary Islands today, and the only hint of a former existence is a ...
Gliding animals change their body shape and posture while producing and modulating aerodynamic forces during flight. However, the combined effect of these different factors on aerodynamic force production, and ultimately the animal’s gliding ability, re

Evolutionary Origins of Viviparity in the Reptilia. II. Serpentes, Amphisbaenia, and Ichthyosauria Superimposition of reproductive mode data from the literature over phylogenetic classification systems reveals that viviparity (live-bearing reproduction) has evolved on at least 35 independent occasions among...
Time and energy constraints and the evolution of sexual size dimorphism — to eat or to mate? We present an empirical test of the 'Ghiselin鈥擱eiss small-male hypothesis' for the evolution of sexual size dimorphism (SSD). In mating systems dominated... WU Blanckenhorn,RF Preziosi,DJ Fairbai...
Although birds are among the best-known groups of vertebrates in terms of biology and ecology2,4,19, there are still knowledge gaps regarding the digestive systems of birds of various body sizes in the context of their feeding and breeding ecology1,5,6,12,13. This is mainly because detailed...
