Interactions between natural selection and environmental change are well recognized and sit at the core of ecology and evolutionary biology. Reciprocal interactions between ecology and evolution, eco-evolutionary feedbacks, are less well studied, even though they may be critical for understanding the evolution of biological diversity, the structure of communities and the function of ecosystems....

Nitellopsis obtusa (starry stonewort) is a dioecious green alga native to Europe and Asia that has emerged as an aquatic invasive species in North America. Nitellopsis obtusa is rare across large portions of its native range, but has spread rapidly in northern-tier lakes in the United States, where it can interfere with recreation and may displace native species. Little is known about the invas...

Boivin et al.’s (1) article profoundly deepens scientific understanding of anthropogenic global ecological change from Pleistocene to present by offering robust new evidence of early human transformation of the biosphere that should influence discussions on Anthropocene formalization (2, 3). As ecologists and evolutionary theorists, we applaud this work. However, we are also concerned that this...

Species utilizing a wide range of resources are intuitively expected to be less efficient in exploiting each resource type compared to species which have developed an optimal phenotype for utilizing only one or a few resources. We report here the results of an empirical study whose aim was to test for a negative association between habitat niche breadth and foraging performance. As a model syst...

The species-area relationship (SAR) is one of the most thoroughly investigated empirical relationships in ecology. Two theories have been proposed to explain SARs: classical island biogeography theory and niche theory. Classical island biogeography theory considers the processes of persistence, extinction, and colonization, whereas niche theory focuses on species requirements, such as habitat a...

The downside of diversity: a tropical problem? The most biodiverse communities in the world are located in the tropics [6]. Tropical species are widely believed to be more sensitive to climate change than their temperate counterparts because of (i) the absence of a marked latitudinal gradient of temperature within the tropics, which risk of species loss – we cannot afford to wait to construct m...
