Temperature profoundly impacts both the phenotypes and distributions of organisms. These
thermal effects exert strong selective pressures on behaviour, physiology and life history …

What are the causes of natural selection? Over 40 years ago, Van Valen proposed the Red
Queen hypothesis, which emphasized the primacy of biotic conflict over abiotic forces in …

Mutualisms–cooperative interactions among different species–are known to influence global
biodiversity. Nevertheless, theoretical and empirical work has led to divergent hypotheses …

Avian parents and social insect colonies are victimized by interspecific brood parasites—
cheats that procure costly care for their dependent offspring by leaving them in another …

Coevolutionary interactions between species are thought to be an important cause of
evolutionary diversification. Despite this general belief, little theoretical basis exists for …

Coevolutionary diversification is cited as a major mechanism driving the evolution of
diversity, particularly in plants and insects. However, tests of coevolutionary diversification …

Because coevolution takes place across a broad scale of time and space, it is virtually
impossible to understand its dynamics and trajectories by studying a single pair of …

Although coevolution is widely recognized as an important evolutionary process for pairs of
reciprocally specialized species, its importance within species-rich communities of …

Species that coexist in diverse natural communities interact in complex ways that alter each
other's abundances and affect selection on each other's traits. Consequently, predicting trait …

Evolutionary conflict occurs when two parties can each affect a joint phenotype, but they
gain from pushing it in opposite directions. Conflicts occur across many biological levels and …
