Blood testosterone level and growth of castrated, uncastrated, and cryptorchid lambs
Semina: Ciências Agrárias, 2017 The objective of this study was to evaluate the effects of sexual status on blood testosterone levels and its influence on lamb growth. A total of 49 Texel x Corriedale males, originating of single births, were divided into three groups: uncastrated (n =

Oikos, Volume 2026, Issue 7, July 2026.Population growth reflects the combined influence of regulation and density‐independent factors operating through demographic processes. Under exceptional circumstances (e.g. populations recovering from near‐extinction), growth may initially be weakly regulated but typically slows as negative density dependence (NDD) sets in.

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.This study investigated the in vitro effects of green tea extract (GTE) and (+)‐catechin on semen quality parameters of Arabi rams during chilled storage. The results showed that GTE and catechin enhance semen parameters during chilled storage, with optimal effects at specific concentrations.

Functional Ecology, Volume 40, Issue 7, Page 2023-2037, July 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract The hormone insulin‐like growth factor 1 (IGF‐1) is a key player in the insulin/IGF signalling (IIS) pathway. Extensive biogerontological research demonstrates that this evolutionarily conserved nutrient‐sensing pathway plays a causal role in the regulation of growth ...

Molecular Ecology Resources, Volume 26, Issue 5, July 2026.ABSTRACT Given the high levels of endemism, diversity, and increasing anthropogenic impacts in tropical regions, studies on species interactions and ecological networks are urgently needed to understand community responses to environmental change. Increasingly, molecular methods are used to monitor biodiversity and identify species interactions.

Methods in Ecology and Evolution, Volume 17, Issue 7, Page 2234-2252, July 2026.Abstract Structured population models are parameterized to accurately project expected population sizes, stage/state distributions and population growth rates, but they also predict the variation in outcomes among individuals, such as the variance and skewness of lifetime reproductive output (LRO) and lifespan, the probability of never reproducing, and
