Acta Scientiarum: Animal Sciences, 2011 Pesquisas efetivas que avaliam a eficiência dos rebanhos bovinos na região Norte do Brasil são insipientes. Por isso, objetivou-se avaliar as mudanças genéticas aditivas diretas e maternais dos pesos padronizados para 205 (P205), 365 (P365) e 550 (P550 ...

Plant, Cell &Environment, Volume 49, Issue 12, Page 9694-9710, December 2026.ABSTRACT Understanding intraspecific variation in drought tolerance is essential for predicting the adaptive capacity of forest species under climate change. Yet, the molecular basis of this variation remains poorly understood in ecologically and economically important conifers.

World Food Policy, Volume 12, Issue 2, November 2026.ABSTRACT Agricultural development initiatives in sub‐Saharan Africa have emphasized improved crop varieties as a pathway to food security, resilience, and rural poverty reduction. However, empirical evidence often focuses narrowly on plot‐level outcomes and overlooks whole‐farm effects and the substantial heterogeneity in farmers' management practices,

Advancing multi‐objective optimization in spatial planning
Journal of Applied Ecology, Volume 63, Issue 11, November 2026.Our framework enables conservation scientists, planners and practitioners to identify spatial plans that achieve multiple objectives. It is designed to help explore trade‐offs across a broad range of domains, including terrestrial, marine and freshwater realms.

Methods in Ecology and Evolution, Volume 17, Issue 11, Page 3245-3259, November 2026.Abstract Tropical dry ecosystems (TDEs) cover half of the tropics and play a key role in global carbon dynamics. TDEs present distinct canopy and ground layers that often exhibit contrasting phenological patterns. On‐the‐ground observations of phenology by the human eye, though valuable, may suffer from limited temporal resolution and observer biases ...

Molecular Ecology, Volume 35, Issue 21, November 2026.ABSTRACT Ancestral adaptive variation is thought to play an important role in facilitating adaptation to insular environments. However, to properly evaluate its role, we need to determine the age of genetic variation. In this study, we investigate the Iago sparrow (Passer iagoensis), a generalist endemic to the Cabo Verde archipelago, to understand how
