Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals

open access: yesIntegrative Zoology, EarlyView.
This schematic depicts the cardiovascular adaptations of mammals and birds to high‐altitude hypoxia. It highlights key phenotypic changes in oxygen transport and cardiac responses, driven by molecular mechanisms including transcriptional regulation and genetic modifications.

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 ...

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

An All‐in‐One Metabarcoding Approach to Mosquito and Arbovirus Xenosurveillance

open access: yesMolecular Ecology Resources, EarlyView.
ABSTRACT Next‐generation sequencing (NGS) has the potential to transform mosquito‐borne disease surveillance but remains under‐utilised. This study introduces a comprehensive multi‐loci metabarcoding‐based MX (molecular xenomonitoring) approach to mosquito and arbovirus surveillance, enabling parallel identification of mosquito vectors, circulating ...

Predicted foot and mouth disease virus and African swine fever virus inactivation within carcases undergoing field decomposition in three Australian climate zones

open access: yesAustralian Veterinary Journal, EarlyView.
Australia's large populations of feral and extensively farmed livestock pose challenges to implementing response plans in the event of an Emergency Animal Disease outbreak. This study aimed to determine if a “Destroy and Let Lie” approach to carcase disposal (leaving carcases in situ to decompose naturally after field euthanasia) would reliably ...
