Early‐life environment drives long‐term decrease in adult body mass in a wild bird population

Journal of Animal Ecology, EarlyView.
Using more than 90,000 body mass measures of adult and nestling great tits Parus major, we show that the 1 SD decline in adult mass between 1978 and 2024 is a consequence of changes in the environment (i.e. increase in population density) experienced at early life.

Production of Cloned Bighorn Sheep Embryos Using ISCNT via HMC from Domestic Sheep Oocytes Treated with Resveratrol During IVM

Animals
The aim of this study was to treat sheep oocytes with resveratrol during in vitro maturation (IVM) and use them as cytoplasts in ISCNT via handmade cloning (HMC), evaluating the effect of resveratrol on the in vitro development of cloned Mexican bighorn ...

The Relationships Between Rodent Control Efforts, Abundance, Damage, and Outcomes

Integrative Zoology, EarlyView.
Diminishing returns on investment are a common pattern in agricultural and biodiversity conservation studies. A review shows few such studies of the effort‐outcomes relationship for rodent control efforts. It is recommended that future rodent control studies estimate such effort‐outcome relationships. ABSTRACT Rodents cause damage to agricultural crops

Integrated Multi‐Omics Analysis Reveals the Genetic Basis of Phenotypic Variation in Tibetan Sheep

Integrative Zoology, EarlyView.
SNaPshot‐validated GWAS results demonstrated significant correlations between candidate single nucleotide polymorphisms (SNPs) and body size traits in Tibetan sheep. Concurrently, hematoxylin and eosin staining, alongside muscle fiber analysis, confirmed pronounced morphological differences in muscle tissue between sheep of varying conformation.

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.
