Habitat Features, Coyotes, and Humans Drive Diel Activity Variation Among Sympatric Mammals
Integrative Zoology, EarlyView.We found that multiple mammal species show considerable variation in diel activity in response to several factors, with biotic variables (habitat features and the presence of coyotes Canis latrans) having the strongest overall effects. Our results have important implications for trophic dynamics. Future studies will need to account for these underlying

Integrative 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‐

Canonical correlation analysis of high-dimensional data with very small sample support [PDF]
, 2016 This paper is concerned with the analysis of correlation between two high-dimensional data sets when there are only few correlated signal components but the number of samples is very small, possibly much smaller than the dimensions of the data. In such a

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

Candidatus ‘Rickettsia senegalensis’ in cat fleas in Senegal
New Microbes and New Infections, 2015 Epidemiological studies of Rickettsia felis and related bacteria are very important, because the natural cycle of this important infection has not yet been established. The recent emergence of R.

Evidence of Bartonella spp., Rickettsia spp. and Anaplasma phagocytophilum in domestic, shelter and stray cat blood and fleas, Portugal. [PDF]
, 2015 Thirty-two fleas were collected from 18 Lisboncats, 29 of which (90.6%) were C. felis, one (3.1%)was C. canis and two (6.3%) were unidentifiable. Only C. felis fleas were infected, six (40.0%)withB. clarridgeiae and six (40.0% ) with R. felis; three(20.0%

Integrative Zoology, EarlyView.Vegetation cover promotes rodent activity and acorn dispersal, while wild boars exert a direct negative effect on mice. Conversely, deer and predators displayed no significant impact on rodent behavior. These results identify wild boars as the main disruptors of rodent‐mediated forest regeneration.
