Coexistence by recruitment variation: How large is the contribution of relative nonlinearity?

Recruitment variation is believed to be an important mechanism of species coexistence in variable environments. This mechanism, however, is a composite of two other mechanisms: the storage effect, and ...

Seasonal variation in atmospheric relative humidity contributes to explaining seasonal variation in trunk circumference of tropical rain-forest trees in French Guiana

Large seasonal variation in the rate of change in girth of tropical rain-forest tree species has been described, but its origin is still under debate. We tested whether this variation might be related ...

Environmental variation and the evolution of large brains in birds

Environmental variability has long been postulated as a major selective force in the evolution of large brains. However, assembling evidence for this hypothesis has proved difficult. Here, by ...

Genetic Variation and Relative Catalytic Efficiencies: Lactate Dehydrogenase B Allozymes of Fundulus Heteroclitus

In order to evaluate whether functional differences exist between allelic variants of a B type lactate dehydrogenase (LDH; L-lactate:NAD+ oxidoreductase, EC 1.1.1.27) in the teleost fish Fundulus ...
