Islands have long been recognized as distinctive evolutionary arenas leading to
morphologically divergent species, such as dwarfs and giants. We assessed how body size …

We introduce an R package for fitting Stable Isotope Mixing Models (SIMMs) via both Markov
chain Monte Carlo and Variational Bayes. The package is mainly used for estimating dietary …

Collagen peptide mass fingerprinting of archaeofaunal remains, or Zooarchaeology by Mass
Spectrometry (ZooMS), has increasingly established itself as a valuable tool for improving …

Competition between taxa related to climate changes has been proposed as a possible
factor in Pleistocene megafaunal extinctions, and here we present isotope evidence of the …

Archaeological and paleontological records offer tremendous yet often untapped potential
for examining long-term biodiversity trends and the impact of climate change and human …

For perhaps 30,000 years grizzly bears ranged throughout the mountains and riparian areas
of what would eventually become the southwestern United States. But in a remarkably short …

The advent of novel biomolecular techniques to study the archaeological record has opened
up an extensive range of key research questions and avenues that were previously …
