Cross-species amplification of microsatellite loci in sub-Antarctic seabirds

Microsatellite loci are ideal for testing hypotheses relating to genetic segregation at fine spatio-temporal scales. They are also conserved among closely related species, making them potentially...

Melanin and oxidative stress

Knowledge of melanin chemistry has important implications for the study of the evolutionary ecology of animal pigmentation, but the actual chemical diversity of these widely expressed biological...

The total population of guanacos could double current estimates

Guanacos are thought to have declined in Patagonia mainly as a result of hunting and sheep ranching. Currently accepted estimates of total population size are extrapolated from densities obtained...

Parrots choose old-growth forest

Forest regeneration may reduce the current loss of species due to tropical deforestation, but little is known about the extent and inter-specific variability of this effect. Authors compared the...

Comparative phylogeography of forest-dependent vertebrates

Pleistocene environmental fluctuations had well-characterized impacts on the patterns of within-species divergences and diversity in temperate habitats. Here authors examined the impact the...
