Murray-Darling basin freshwater shells: riverine reservoir effect [PDF]

open access: yes, 2009
We report carbon isotope measurements on pre-bomb museum samples of freshwater mussel shells collected alive from riverine locations in New South Wales, Australia. The calculated reservoir ages, ranging from -60 to +112 years, are much smaller than those

Introduced herbivores restore Late Pleistocene ecological functions [PDF]

open access: yesProceedings of the National Academy of Sciences, 2020
Significance Humans have caused extinctions of large-bodied mammalian herbivores over the past ∼100,000 y, leading to cascading changes in ecosystems. Conversely, introductions of herbivores have, in part, numerically compensated for extinction losses. However, the net outcome of the twin anthropogenic forces of extinction and introduction on

Solving the woolly mammoth conundrum: amino acid 15N-enrichment suggests a distinct forage or habitat [PDF]

open access: yes, 2015
Understanding woolly mammoth ecology is key to understanding Pleistocene community dynamics and evaluating the roles of human hunting and climate change in late Quaternary megafaunal extinctions. Previous isotopic studies of mammoths’ diet and physiology

Geometric morphometrics and paleoproteomics enlighten the paleodiversity of Pongo.

open access: yesPLoS ONE, 2023
Pleistocene Pongo teeth show substantial variation in size and morphology, fueling taxonomic debates about the paleodiversity of the genus. We investigated prominent features of the enamel-dentine-junction junction (EDJ)-phylogenetically informative ...
