High mitogenomic evolutionary rates and time dependency.
Using entire modern and ancient mitochondrial genomes of Adélie penguins (Pygoscelis adeliae) that are up to 44000 years old, we show that the rates of evolution of the mitochondrial genome are twoExpand

Integrating Stomach Content and Stable Isotope Analyses to Quantify the Diets of Pygoscelid Penguins
Stomach content analysis (SCA) and more recently stable isotope analysis (SIA) integrated with isotopic mixing models have become common methods for dietary studies and provide insight into theExpand

Abrupt recent shift in δ13C and δ15N values in Adélie penguin eggshell in Antarctica
Stable isotope values of carbon (δ13C) and nitrogen (δ15N) in blood, feathers, eggshell, and bone have been used in seabird studies since the 1980s, providing a valuable source of information onExpand

Diving behavior of blue-footed boobies Sula nebouxii in northern Peru in relation to sex, body size and prey type
We studied the diving behavior and diet of the sexually size-dimorphic blue-footed booby Sula nebouxii (BFB) breeding on Isla Lobos de Tierra, Peru, to evaluate whether sexual dimor- phism isExpand

AVIAN PREDATION AT PENGUIN COLONIES ON KING GEORGE ISLAND, ANTARCTICA
Predation at seven colonies that varied in size from 10 to hundreds of breed- ing pairs of Adelie (Pygoscelis adeliae) and Gentoo (P. papua) penguins was observed from a blind at King George Island,Expand
