- Priorities for conserving the world’s terrestrial mammals . . .
To quantify over-the-horizon extinction risk for mammal species, we define, a priori, four future risk factors One is based on high latent risk (which is a single, invariable value for each species), and the other three are based on the severity of projected change in climate, human population density, and land use to the year 2100 (which varies among projection scenarios)
- Predicting the zoonotic capacity of mammals to transmit SARS . . .
Here, we combine structural modelling of viral binding with machine learning of species ecological and biological traits to predict zoonotic capacity for SARS-CoV-2 across 5400 mammal species, expanding our predictive capacity by an order of magnitude Crucially, this integrated approach enables predictions for the vast majority of species
- What is a mammalian omnivore? Insights into terrestrial . . .
Mammalian omnivores are a broad group of species that are often treated uniformly in ecological studies Here, we incorporate omnivorous dietary differences to investigate previously found mammalian macroevolutionary and macroecological trends We investigate the frequency with which

- 2016 Guidelines of the American Society of Mammalogists for the
Guidelines for use of wild mammal species in research are updated from Sikes et al (2011) These guidelines cover current professional techniques and regulations involving the use of mammals in research and teaching; they also incorporate new resources, procedural summaries, and reporting requirements Included are details on capturing,
- Lifespan is unrelated to investment in reproduction in . . .
We examined the relationship between number of offspring produced to a certain age and subsequent longevity in captive zoo populations of 18 species of mammal and 12 species of bird The age cut-offs in each analysis were set to include 50%, 75% and 90% of the offspring produced in each of the popul …
- The rise of the mammals: Fossil discoveries combined with . . .
This interest in the evolution of mammals and plants at the end of the Cretaceous period has only arisen quite recently, although some mammal relics were already described in the original discovery of the dinosaurs in 1824 when naturalist William Buckland presented bones from one of the first known dinosaurs, Megalosaurus, at the Geological Society of London
