Transcriptome-wide analysis reveals different categories of response to a standardised immune challenge in a wild rodent [PDF]

open access: yes, 2020
Individuals vary in their immune response and, as a result, some are more susceptible to infectious disease than others. Little is known about the nature of this individual variation in natural populations, or which components of immune pathways are most

Variation in Oxytocin Receptor Density in the Nucleus Accumbens Has Differential Effects on Affiliative Behaviors in Monogamous and Polygamous Voles

open access: yesJournal of Neuroscience, 2009
Oxytocin receptors in the nucleus accumbens have been implicated in the regulation of alloparental behavior and pair bond formation in the socially monogamous prairie vole.

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.

Sex‐Specific Involvement of Gut Microbiota in Behavioral and Endocrine Responses to Chronic Predator Odor in Brandt's Voles

open access: yesIntegrative Zoology, EarlyView.
18 days of predator odor exposure altered gut microbiota, increased anxiety‐like behaviors, and elevated hypothalamic–pituitary–adrenal axis activity in Brandt's voles, with males showing behavioral habituation and females remaining sensitive. Cecal microbiota transplantation experiments confirmed that only female recipients of microbiota from predator‐

Prenatal Environmental Hypoxia Enhances Adult Hypoxia Tolerance in Brandt's Voles (Lasiopodomys brandtii): Behavioral and Transcriptomic Insights

open access: yesIntegrative Zoology, EarlyView.
Prenatal hypoxia enhances adult hypoxia tolerance in Brandt's voles, preserving cognitive and memory functions. Transcriptomic analysis reveals adaptive changes in energy metabolism, oxygen transport, and neuroprotective mechanisms, highlighting developmental plasticity.

Do bank voles (Myodes glareolus) trapped in live and lethal traps show differences in tick burden?

open access: yesPLoS ONE, 2020
In studies assessing tick abundance, the use of live traps to capture and euthanize rodent hosts is a commonly used method to determine their burden.

Studies of Birds and Mammals in the Baird and Schwatka Mountains, Alaska [PDF]

open access: yes, 1974
In 1963 a joint University of Alaska-Smithsonian Institution crew worked at five locations in the Baird and Schwatka mountains in northwestern Alaska, conducting an ecological reconnaissance and faunal and floral inventory.

Museomics Deciphers the Phylogeographic Differentiation and Conservation Status of a Montane Pheasant

open access: yesIntegrative Zoology, EarlyView.
Museum specimens provide a rich source of historical DNA, enabling insights into phylogenetic relationships and demographic history of the endangered Koklass Pheasant. Our findings uncovered a previously unrecognized population in Guizhou province and highlighted elevated extinction risk in populations from Anhui province and Southern China, informing ...

Can hierarchical modelling of co‐occurrence data provide accurate inference into species interactions?

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract In recent years, several compelling critiques have emerged of approaches that leverage co‐occurrence data to understand the dynamic complexities posed by species interactions. Here, motivated by the key arguments formalized over a century of debate, we use simulations grounded in ecological theory to provide guidance on when co‐occurrence data
