The accelerating influence of humans on mammalian macroecological patterns over the late Quaternary [PDF]

open access: yes, 2019
The transition of hominins to a largely meat-based diet ~1.8 million years ago led to the exploitation of other mammals for food and resources. As hominins, particularly archaic and modern humans, became increasingly abundant and dispersed across the ...

Establishing macroecological trait datasets: digitalization, extrapolation, and validation of diet preferences in terrestrial mammals worldwide [PDF]

open access: yes, 2014
Ecological trait data are essential for understanding the broad-scale distribution of biodiversity and its response to global change. For animals, diet represents a fundamental aspect of species’ evolutionary adaptations, ecological and functional roles,

The Biodiversity of Peter I Island—The Most Remote Island in the World

open access: yesEcology and Evolution, Volume 15, Issue 11, November 2025.
Peter I Island is one of the most isolated and least visited islands on earth; lying within the Antarctic Polar Front but over 420 km from continental Antarctica. Here we assess the biodiversity of the island from both previous records and our own BioBlitz in January 2022.

An Exploration of DNA Extraction Methods of Fly iDNA for Scalable Biodiversity Monitoring

open access: yesEnvironmental DNA, Volume 7, Issue 6, November–December 2025.
Metabarcoding of invertebrate‐derived DNA (iDNA) is an excellent tool for assessing terrestrial mammal diversity, but the time and costs associated with sample processing constrain its wider adoption. Our study indicates that the non‐destructive extraction of large pools of entire fly bodies has the potential to streamline and reduce the costs of fly ...
