Relationships Between European Wildcats and Domestic Cats in an Area of Sympatry: Exploring Key Conservation Questions on Hybridization and Disease Transmission

open access: yesAnimal Conservation, EarlyView.
We have found evidence of behavioural barriers for both hybridization and disease transmission between European wildcats and domestic cats. This includes hierarchical interspecies exclusion enforced by wildcats, as well as sexual selection exerted by wildcat females.

Morphometric and Paleobiological Insights Into Pleistocene Sicilian Wolf Populations

open access: yesActa Zoologica, EarlyView.
ABSTRACT The Pleistocene wolves (Canis lupus) from Sicily represent one of the few known insular populations of this species from that time period. Despite their potential relevance for understanding carnivore adaptations in insular contexts, no dedicated study has previously investigated their morphology and evolutionary significance.

Pharmacological inhibition of hydroxysteroid 11‐beta dehydrogenase type 1 (11‐βHSD1) after myocardial infarction preserves cardiac function in a translational mini‐pig model

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Plasma glucocorticoids increase acutely after MI, thereafter tissue levels are amplified selectively within cells expressing 11‐ßhydroxysteroid dehydrogenase type 1 (11‐ßHSD1) that regenerates active glucocorticoids from circulating metabolites.

Lessons from an eradication under multiple constraints of an island rat population of record density

open access: yesConservation Biology, EarlyView.
Abstract Invasive rats threaten island biodiversity, disrupting ecosystems and endangering native species. Although rat eradication has succeeded on many islands, tropical islands present unique management challenges. Strict regulations and financial constraints on some tropical islands further limit proven eradication methods, complicating rodent ...

Estimating site occupancy for four threatened mammals in southeastern Laos [PDF]

open access: yes, 2014
textThe tropical forests of Indochina harbor a suite of globally threatened tropical mammal species. These species are difficult to detect, and subsequently understudied. Noninvasive camera trapping was used to survey terrestrial mammals from a protected

Temporally‐indexed multi‐species density impact functions: Quantifying timing and impact of invasive predators on seabird breeding success

open access: yesConservation Science and Practice, EarlyView.
Conserving threatened species often requires effective predator suppression strategies, particularly on islands where introduced predators pose significant threats. Density‐impact functions provide a framework to quantify the relationships between predator abundance and impact but are currently limited to a single species with invariant impact.

A suture in time: The ontogeny of cranial suture morphology in mammals

open access: yesJournal of Anatomy, EarlyView.
Mammal cranial sutures are important indicators of the biomechanical and developmental pressures acting upon the skull. Across three prominent sutures dividing the vault of the mammalian skull, divergent patterns emerge both taxonomically and developmentally.
