Global Proteomic Analysis of Sperm and Seminal Plasma From Tropically-Adapted Rams With Contrasting Parameters of Frozen-Thawed Semen. [PDF]

Mol Reprod Dev
ABSTRACT The aim of this study was to characterize the proteome of sperm and seminal plasma (SP) from rams with high semen freezability (HF) and low semen freezability (LF). Eleven ejaculates were collected from 12 rams, at 3‐day intervals, and cryopreserved (132 semen samples).

Microclimate refugia shape microclimatic niches and predict individual variability in post-breeding migration in a partially migratory species. [PDF]

J Anim Ecol
The niche is characterized along a gradient of temperature and microclimate refugia. Individuals in breeding areas with low microclimate refugia availability are more likely to cover larger distances to post‐breeding areas, increasing exposure to risks.

Synchronization of stage of follicle development before OPU improves embryo production in cows with large antral follicle counts

, 2020
In the present study, there was an evaluation of in vitro embryo production (IVEP) in Bos indicus donor cows with small or large antral follicle counts (AFCs) when there was synchronization of follicular dynamics among cows before ovum pick-up (OPU ...

Pruning slash drives ambrosia beetle (Curculionidae: Scolytinae, Platypodinae) activity in Khaya grandifoliola C.DC.: Slash removal as a preventive management strategy Resíduos de poda aumentam a atividade de besouros da ambrosia (Curculionidae: Scolytinae, Platypodinae) em Khaya grandifoliola C.DC.: A remoção dos resíduos como estratégia preventiva de manejo

Agricultural and Forest Entomology, Volume 28, Issue 4, Page 677-684, November 2026.
Slash retention increased ambrosia beetle activity in Khaya grandifoliola, acting as both breeding substrate and source of attractive volatile cues that promoted localized population buildup. Beetle attacks occurred only near retained slash, while no attacks were recorded in slash‐removal plots, demonstrating that residue removal effectively prevents ...

Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

Journal of Animal Ecology, Volume 95, Issue 10, Page 1859-1875, October 2026.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...
