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

J 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]

J 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.

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

Agricultural 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.

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

Plant Biology, EarlyView.
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.

Integrative chromosome‐scale genome analysis of cupuassu provides insights into witches' broom disease resistance and expands genomic resources for Theobroma

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Cupuassu (Theobroma grandiflorum) is a fruit tree native to the Brazilian Amazon and increasingly relevant to regional bioeconomies. Its cultivation is severely affected by witches’ broom disease (WBD), caused by Moniliophthora perniciosa. While a chromosome‐scale genome of the susceptible genotype C1074 is available, the lack of a resistant ...

Molecular and Serological Detection of Coxiella burnetii in Small Ruminants in Northeastern Brazil

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
• Serology indicates that one‐third of the sheep and goats had previously been infected with Coxiella burnetii. • qPCR analysis revealed the ongoing presence of C. burnetii in all evaluated flocks, each with a previous history of reproductive disorders. • These results indicate the need for preventive measures and control of C.

Nutritional and Fermentative Impacts of Adding Dehydrated Cashew Pseudofruit to Elephant Grass Silage

New Zealand Journal of Agricultural Research, Volume 69, Issue 1, February 2026.
The article evaluated the effect of different levels of dehydrated cashew pseudofruit (DCP; 0%, 10%, 20%, and 30% based on natural matter) on the ensiling of Cenchrus purpureus BRS Capiaçu (Elephant grass), focusing on fermentative characteristics, nutrient composition, losses, and aerobic stability.

The association of Mediterranean plant species with herbivorous arthropods and its effect on pest abundance in organic vineyards

Annals of Applied Biology, Volume 188, Issue 1, Page 369-385, January 2026.
We determined the associations of native Mediterranean plant species located around organic vineyards with species of Auchenorrhyncha and phytophagous tetranychid and tenuipalpid mites, including important vineyard pests: Jacobiasca lybica and Tetranychus urticae.
