Terrestrial biodiversity is dominated by plants and the herbivores that consume them, and
they are one of the major conduits of energy flow up to higher trophic levels. Here, we …

Divergent natural selection has been shown to promote speciation in many taxa. However,
although divergent selection often initiates the process of speciation, it often fails to complete …

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 …

The origin of biological diversity, via the formation of new species, can be inextricably linked
to adaptation to the ecological environment. Specifically, ecological processes are central to …

Adaptive radiation is the evolution of diversity within a rapidly multiplying lineage. It can
cause a single ancestral species to differentiate into an impressively vast array of species …

Are measurements of quantitative genetic variation useful for predicting long‐term adaptive
evolution? To answer this question, I focus on gmax, the multivariate direction of greatest …

Darwinian Natural Selection t is quite conceiveable," Darwin wrote in his introduction to On
the Origin of Species (1859, p. 3)" that a naturalist, reflecting on the mutual affinities of …

▪ Abstract Classical biological control, ie the introduction and release of exotic insects, mites,
or pathogens to give permanent control, is the predominant method in weed biocontrol …

▪ Abstract Sympatric speciation is the splitting of one evolutionary lineage into two without
the occurrence of geographic isolation. The concept has been intimately tied to entomology …

One of the most important shifts in evolutionary biology in the past 50 years is an increased
recognition of sluggish evolution and failures to adapt, which seem paradoxical in view of …
