Data from: Does morphological variation buffer against extinction? A test using veneroid bivalves from the Plio-Pleistocene of Florida

Sarah E. Kolbe, Rowan Lockwood & Gene Hunt
Although morphological variation is known to influence the evolutionary fates of species, the relationship between morphological variation and survivorship in the face of extinction-inducing perturbations is poorly understood. Here, we investigate this relationship for veneroid bivalves in association with the Plio-Pleistocene extinction in Florida. Fourteen pairs of related species were selected for analysis, with each pair including one species that survived the Plio-Pleistocene extinction and another that became extinct during the interval. Morphological landmark data...

Data from: Climatic forcing of Quaternary deep-sea benthic communities in the North Pacific Ocean

Moriaki Yasuhara, Gene Hunt, Thomas M. Cronin, Natsumi Hokanishi, Hodaka Kawahata, Akira Tsujimoto & Miho Ishitake
There is a growing evidence that changes in deep-sea benthic ecosystems are modulated by climate changes, but most evidence to date comes from the North Atlantic Ocean. Here we analyze new ostracod and published foraminiferal records for the last 250,000 years on Shatsky Rise in the North Pacific Ocean. Using linear models, we evaluate statistically the ability of environmental drivers (temperature, productivity, and seasonality of productivity) to predict changes in faunal diversity, abundance and composition....

Data from: A passerine bird's evolution corroborates the geologic history of the island of New Guinea

Kristy Deiner, Alan R. Lemmon, Andrew L. Mack, Robert C. Fleischer & John P. Dumbacher
New Guinea is a biologically diverse island, with a unique geologic history and topography that has likely played a role in the evolution of species. Few island-wide studies, however, have examined the phylogeographic history of lowland species. The objective of this study was to examine patterns of phylogeographic variation of a common and widespread New Guinean bird species (Colluricincla megarhyncha). Specifically, we test the mechanisms hypothesized to cause geographic and genetic variation (e.g., vicariance, isolation...

Data from: Evolutionary diversification of reef corals: a comparison of the molecular and fossil records

Carl Simpson, Wolfgang Kiessling, Heike Mewis, Rosemarie C. Baron-Szabo & Johannes Müller
Understanding historical patterns of diversity dynamics is of paramount importance for many evolutionary questions. The fossil record has long been the only source of information on patterns of diversification, but the molecular record, derived from time-calibrated phylogenies, is becoming an important additional resource. Both fossil and molecular approaches have shortcomings and biases. These have been well studied for fossil data but much less so for molecular data and empirical comparisons between approaches are lacking. Here...

Data from: Insects on plants: explaining the paradox of low diversity within specialist herbivore guilds

Vojtech Novotny, Scott E. Miller, Jan Hrcek, Leontine Baje, Yves Basset, Owen T. Lewis, Alan J. A. Stewart & George D. Weiblen
Classical niche theory explains the coexistence of species through their exploitation of different resources. Assemblages of herbivores coexisting on a particular plant species are thus expected to be dominated by species from host-specific guilds with narrow, coexistence-facilitating niches, rather than by species from generalist guilds. Exactly the opposite pattern is observed for folivores feeding on trees in New Guinea. The least specialized mobile chewers were most species-rich, followed by the moderately specialized semi-concealed and exposed...
