Genetic Parameter Estimation for Pregnancy Loss and Their Association With Reproductive and Growth Traits in Brahman Cattle Under Extensive Tropical Conditions. [PDF]

open access: yesJ Anim Breed Genet
ABSTRACT This study estimated genetic parameters for pregnancy loss (PL) in Brahman cattle and evaluated the genetic correlation of PL with growth and reproductive traits using both the pedigree relationship matrix (A) and pedigree plus genomic relationship matrix (H). Data were collected from two herds in Bolivia, focusing on three age groups: heifers,

Genomic Prediction and Genome-Wide Association Analysis of Heat Tolerance for Milk Yield in Buffaloes Using a Reaction Norm Model. [PDF]

open access: yesJ Anim Breed Genet
ABSTRACT The aim of this study was to evaluate the impact of incorporating genomic information on the estimation of genetic (co)variance components and the accuracy of breeding values for milk yield under varying thermal environments, and to identify SNPs associated with genes that play significant roles in heat tolerance.

Sinningia pampeana sp. nov. (Gesneriaceae) from the Pampa's rocky outcrops in southern Brazil and Uruguay

open access: yesNordic Journal of Botany, EarlyView.
Sinningia pampeana is a new rupicolous species from the rocky outcrops of the Pampa biome in southern Brazil and Uruguay. Morphological analyses based on herbarium material, field observations, and detailed illustrations support its recognition as a distinct species from Sinningia sellovii.

Evaluation of systemic consequences of brachycephalic obstructive airway syndrome in dogs

open access: yesVeterinary Record, EarlyView.
Abstract Background Brachycephalic obstructive airway syndrome (BOAS) results from upper airway anatomical abnormalities and may cause systemic effects depending on severity. Methods A prospective, case‒control and observational study was conducted.

Hidden Losses: Assessing the Risk of Coextinction Among Ectoparasitic Flies and Their Bat Host Species in Brazil

open access: yesAnimal Conservation, EarlyView.
The potential impact of bat species extinction on the number of their ectoparasitic fly species, based on interaction data for Brazil. As bat host species are removed over time, more connected species (green) would experience steeper declines and lead to greater ectoparasite losses when compared to a random extinction model (gray).

Monitoring spirodiclofen resistance in female Brevipalpus yothersi (Acari: Tenuipalpidae) from citrus orchards in Southeastern Brazil

open access: yesAgricultural and Forest Entomology, EarlyView.
Spirodiclofen resistance levels in B. yothersi varied geographically across the Brazilian citrus belt, with higher resistance in the central region. Sublethal effects included reduced oviposition, increased non‐viable eggs and disrupted female reproduction.

Renal Perfusion in Healthy Horses: A Feasibility Study With Contrast‐Enhanced Ultrasound

open access: yesVeterinary Radiology &Ultrasound, Volume 67, Issue 4, July 2026.
ABSTRACT This study assessed the feasibility of contrast‐enhanced ultrasound (CEUS) for evaluating renal perfusion in horses and compared perfusion parameters between age groups. In a prospective study, eight healthy horses were divided into young (3–5 years, n = 4) and old (16–17 years, n = 4) groups.

Genomic Variation and Population Structure of Portuguese Native Dog Breeds

open access: yesAnimal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT The presence of dogs in Portugal is confirmed by zooarchaeological evidence dating to at least 7600 years ago. The 11 native dog breeds that exist in this territory are therefore the end‐product of a complex evolutionary process. This study characterises the genomic diversity and population structure of 10 native breeds based on whole‐genome ...

Making the most of hard‐won data: Incorporating commonly discarded information from unidentifiable samples improves precision and cost‐effectiveness in wolf population monitoring

open access: yesJournal of Applied Ecology, Volume 63, Issue 6, June 2026.
RT‐SCR provides a principled and cost‐effective way to recover information from samples that are usually discarded, improving both precision and the reliability of parameter estimates without extra field or laboratory investment. Gains were strongest for shared ecological parameters, including detection, space use and habitat associations, and are ...

Effects of post‐fire on seed germination and seedling recruitment of a generalist savanna woody species

open access: yesPlant Biology, Volume 28, Issue 4, Page 1190-1197, June 2026.
Vegetation type and microclimate shape recruitment of a generalist tree seedling, while fire history alters cotyledon use over time. Abstract Temperature and humidity are key factors influencing seed germination, varying across vegetation types and in response to disturbances such as fire.
