Assessment of cow and farm level risk factors associated with Ureaplasma diversum in pasture-based dairy systems - A field study

open access: yesAnais da Academia Brasileira de Ciências, 2017
Potential risk factors for Ureaplasma diversum in the vaginal mucus of 1,238 dairy cows were included in a multivariate logistic regression model, based on the cow level (i.e., granular vulvovaginitis [+GVV], yearly milk production [4500 kg or more ...

Vision at high latitudes: High sensitivity without specific boreal adaptations in photoreception in reindeer (Rangifer tarandus L.)

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The light climate at high latitudes, in particular the extended twilight of winter and the reduced diel variation in light level in midsummer and midwinter, potentially constrains visual function and the synchronisation of temporal organisation in polar species. In this

Network dynamics revealed from eDNA highlight seasonal variation in urban mammal communities

open access: yesJournal of Animal Ecology, EarlyView.
Our novel study applied eDNA to track seasonal shifts in urban mammal communities, revealing changes in diversity and species interaction networks across 21 urban parks in Detroit. We highlight the influence of park size and human activity on biodiversity, demonstrating the utility of eDNA for urban conservation and wildlife management.

Molecular Method Based on Hydrolysis Probe Assays to Identify the Sex Chromosomes of Iberian Desman (Galemys pyrenaicus) Using Non‐Invasive Sampling

open access: yesIntegrative Zoology, EarlyView.
To monitor populations of an endangered species such as Galemys pyrenaicus in the Extremadura area, qPCR techniques have been used to determine sex, using non‐invasive sampling techniques. ABSTRACT Desmans belong to the subfamily Desmaninae, which are members of the family Talpidae.

Validating a Target‐Enrichment Design for Capturing Uniparental Haplotypes in Ancient Domesticated Animals

open access: yesMolecular Ecology Resources, EarlyView.
ABSTRACT In the last three decades, DNA sequencing of ancient animal osteological assemblages has become an important tool complementing standard archaeozoological approaches to reconstruct the history of animal domestication. However, osteological assemblages of key archaeological contexts are not always available or do not necessarily preserve enough
