Maternal glucocorticoids have persistent effects on offspring social phenotype irrespective of opportunity for social buffering

open access: yesJournal of Animal Ecology, EarlyView.
This study tests whether early‐life maternal association buffers offspring from the effects of prenatal stress in a facultatively social lizard. Despite clear effects of maternal glucocorticoids on growth and social behaviour, social associations did not mitigate these effects, revealing limits to social buffering in this species.

Demographic buffering in natural populations: A multi‐level perspective

open access: yesJournal of Animal Ecology, EarlyView.
We introduce a multi‐level framework that unites stochastic elasticities with nonlinear selection to test demographic buffering. Applying it across mammals reveals a key insight: ecological robustness to variability often decouples from evolutionary constraint, reshaping how we understand resilience under environmental stochasticity.

Diet and coexistence of Rattus rattus rattus (Linnaeus), Rattus exulans (Peale) and Rattus norvegicus (Berkenhout) on Stewart Island, New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Zoology [PDF]

open access: yes, 1988
Coexistence and diet of Rattus rattus rattus, Rattus exulans and, Rattus norvegicus on Stewart Island was investigated by snap-trapping and stomach analysis. The trapping period was from June 1982 to December 1986.

Does Rodent Management Impact the Distribution of Rattus rattus and Mastomys natalensis in Village Settings?

open access: yesIntegrative Zoology, EarlyView.
Ecological differences between species may result in differential impacts of control measures. Our experimental study showed that intensive removal of rodents from houses (mostly Rattus rattus) resulted in increased use of houses by Mastomys natalensis, a species usually found outdoors. Our results suggest that M.

Intra‐ and Interspecific Effects on Spatio‐Temporal Behavior of Common Commensal Rodent Species

open access: yesIntegrative Zoology, EarlyView.
This study revealed major findings on spatio‐temporal behavior of commensal rodents on a pig farm showing the influence of interspecific dominance on movement behavior and the resulting species‐specific ecological adaptations. Additionally, rodents tend to stay in their home ranges and migration to other stable buildings is only rare.

Ectoparasite-borne Bartonella and Rickettsia in Chilean populations of Rattus rattus: prevalence, genetic diversity and environmental associations

open access: yesParasitology
Rattus rattus is a known reservoir of zoonotic pathogens, including Bartonella and Rickettsia, transmitted by ectoparasites such as fleas, mites, lice and ticks.

Extinction Debt Paid Off: The Demise of the European Polecat (Mustela putorius) in NE Iberia

open access: yesIntegrative Zoology, EarlyView.
We studied a vanishing polecat population for a decade, until its ultimate demise, using camera trap and roadkill data, landscape descriptors and dietary and toxicological analyses.Polecat favoured farmland and avoided forests and water bodies occupied by the invasive American mink.

Phylogenetic and Functional Originality Shape Species Positions in Flea–Mammal Networks Across Biogeographic Realms

open access: yesIntegrative Zoology, EarlyView.
The relationship between the position of a flea species in the networks and its functional originality was found to be consistently positive in all realms, independently of which originality index was used. ABSTRACT We investigated the relationships between a species’ network position (measured as the combined normalized degree, species strength, and ...
