Evolutionary biologists tend to approach the study of the natural world within a framework of
adaptation, inspired perhaps by the power of natural selection to produce fitness …

Climate change is predicted to be most severe in northern regions and there has been
much interest in to what extent organisms can cope with these changes through phenotypic …

Evolutionary quantitative genetics seeks to quantify sources of genetic variation in fitness-related
traits to assess the potential for traits to respond to future natural selection and to infer …

In fluctuating environments, mothers may enhance the fitness of their offspring by adjusting
offspring phenotypes to match the environment they will experience at independence. In free-…

Adaptations to the cold and to short growing seasons characterize arctic life, but climate in
the Arctic is warming at an unprecedented rate. Will plant and animal populations of the Arctic …

Mast seeding, the intermittent, synchronous production of large seed crops by a population
of plants, is a well-known example of resource pulses that create lagged responses in …

Background Our understanding of gut microbiota has been limited primarily to findings from
human and laboratory animals, but what shapes the gut microbiota in nature remains largely …

The potential importance of life history traits to population growth rates has been well explored
theoretically but has rarely been documented in wild mammals. In this study we used 18 …

Altruism presents a challenge to evolutionary theory because selection should favor selfish
over caring strategies. Greenbeard altruism resolves this paradox by allowing cooperators to …

Mast seeding involves the episodic and synchronous production of large seed crops by
perennial plants. The predator satiation hypothesis proposes that mast seeding maximizes seed …
