Understanding the relationships between biodiversity and ecosystem functioning has major
implications. Biodiversity–ecosystem functioning relationships are generally investigated at …

Human activity is causing wild populations to experience rapid trait change and local
extirpation. The resulting effects on intraspecific variation could have substantial …

In recent years, scientists have realized that evolution can occur on timescales much shorter
than the" long lapse of ages" emphasized by Darwin—in fact, evolutionary change is …

Omnivory, feeding at more than one trophic level, is a prevalent feature of freshwater
ecosystems. Understanding where and when omnivory is important, its relevance for …

Historically, many biologists assumed that evolution and ecology acted independently
because evolution occurred over distances too great to influence most ecological patterns …

Mutations of small effect underlie most adaptation to new environments, but beneficial
variants with large fitness effects are expected to contribute under certain conditions. Genes …

Evolutionary hypotheses to explain the greater numbers of species in the tropics than the
temperate zone include greater age and area, higher temperature and metabolic rates, and …

Abstract In the Baltic Sea, the mesopredator three-spined stickleback (Gasterosteus
aculeatus) spends a large part of its life cycle in the open sea, but reproduces in shallow …

The relationship between omnivory and stability has been the subject of a longstanding
debate in ecology. Early theory predicted that omnivory would decrease the probability of …

The inherently multidimensional nature of the niche has not yet been integrated into the
investigation of individual niche specialization within populations. We propose a framework …
