Biotic interactions drive key ecological and evolutionary processes and mediate ecosystem
responses to climate change. The direction, frequency, and intensity of biotic interactions …

Highlights•Fossil plant–insect interactions record herbivory, pollination, mimicry, and

In addition to their devastating effects on global biodiversity, mass extinctions have had a
long-term influence on the history of life by eliminating dominant lineages that suppressed …

Cynodont therapsids diversified extensively after the Permo-Triassic mass extinction event,
and gave rise to mammals in the Jurassic. We use an enlarged and revised dataset of …

This study examines regional diversity patterns of Permian–Triassic terrestrial vertebrates of
the South African Karoo Basin and the Russian fore-Ural region. Previous studies clearly …

The continuous fossil record of therocephalian therapsids (Eutheriodontia) across the Permo-
Triassic boundary and their differential survivorship of the end-Permian extinction offer an …

Paleodiversity trends through geologic time can be affected by a number of geologic,
taphonomic, and anthropogenic biases that obscure or prejudice paleoecological patterns in …

One of the most enduring evolutionary metaphors is Van Valen's (1973) Red Queen.
According to this metaphor, as one species in a community adapts by becoming better able …

This paper develops mathematical models of the tragedy of the commons analogous to
ecological models of resource consumption. Tragedies differ fundamentally from predator …

Abstract The Moradi Formation of northern Niger preserves a rare glimpse of tetrapods
inhabiting the low paleolatitude regions of Pangea during Late Permian times. In contrast to …
