Rates of Evolution in Ancient DNA from Adélie Penguins
Well-preserved subfossil bones of Adélie penguins,Pygoscelis adeliae, underlie existing and abandoned nesting colonies in Antarctica. These bones, dating back to more than 7000 years before theExpand

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

Abandoned penguin rookeries as Holocene paleoclimatic indicators in Antarctica
Penguins are sensitive indicators of the Antarctic climate and of the environmental parameters that limit their presence and distribution. Paleoenvironmental data, obtained from the study ofExpand

A Common Rule for the Scaling of Carnivore Density
Summary of carnivore density and prey biomass. The number ofcarnivores per 10,000 kg of prey biomass was estimated from the ratio ofcarnivore population density (number per 100 km 2 ) to biomassExpand

Holocene relative sea-level history of the Southern Victoria Land Coast, Antarctica
More than 130 radiocarbon dates of penguin remains and guano, sealskin, shells, and seaweed from raised beach ridges afford relative sea-level information for southern Victoria Land. A new relativeExpand

Historically unprecedented global glacier decline in the early 21st century
Observations show that glaciers around the world are in retreat and losing mass. Internationally coordinated for over a century, glacier monitoring activities provide an unprecedented dataset ofExpand

Mutation and Evolutionary Rates in Adélie Penguins from the Antarctic
Precise estimations of molecular rates are fundamental to our understanding of the processes of evolution. In principle, mutation and evolutionary rates for neutral regions of the same species areExpand

Ancient DNA enables timing of the pleistocene origin and holocene expansion of two adélie penguin lineages in antarctica.
The timing of divergent events in history is one of the central goals of contemporary evolutionary biology. Such studies are however dependent on accurate evolutionary rates. Recent developments inExpand
