Choice of grazed herbage or maize silage by lactating dairy cows: influence of sward height and concentrate level Preferência por pastagem ou silagem de milho por vacas leiteiras em lactação: influência da altura do pasto e do nível de concentrado

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2010
The preference of lactating dairy cows for grazed herbage or maize silage (MS), simultaneously offered ad libitum in the field, was examined at two sward heights (SH 4-6 and 8-10cm) and two concentrate levels (CL 0 and 6kg day-1) in a 2x2 factorial ...

Beyond Ecology: How Environmental and Social Landscapes Shape Tropical Forest Restoration in Southeast Brazil

Biotropica, Volume 58, Issue 2, March 2026.
Restoration was more associated with environmental variables than socioeconomics. Active restoration was utilized in degraded areas and pasture abandonment favored natural regeneration. Successful tropical restoration is dependent on a complex interdependent mix of factors.

Mapping the density of giant trees in the Amazon

New Phytologist, Volume 249, Issue 1, Page 152-168, January 2026.
Summary Tall trees (height ≥ 60 m) are keystone elements of tropical forests, strongly influencing biodiversity, carbon storage, and ecosystem resilience. Yet, their density and spatial distribution remain poorly quantified, especially in remote Amazonian regions, limiting our understanding of their ecological roles and contribution to forest–climate ...

The Future of AI in the GCC Post‐NPM Landscape: A Comparative Analysis of Kuwait and the UAE

Politics &Policy, Volume 53, Issue 6, December 2025.
ABSTRACT Comparative evidence of how two Gulf Cooperation Council (GCC) states translate artificial intelligence (AI) ambitions into post–New Public Management (post‐NPM) outcomes are scarce because most studies focus on Western democracies. To fill this gap, we examine constitutional, collective choice, and operational rules that shape AI uptake in ...

Pixelated pathologies: Camera trapping as a tool for monitoring wildlife health

Journal of Applied Ecology, Volume 62, Issue 11, Page 2894-2913, November 2025.
Given the increasing emergence of diseases, some with conservation and public health implications, improving and expanding wildlife health surveillance strategies is imperative. Camera trapping is particularly relevant for detecting new outbreaks, monitoring high‐risk zones and evaluating risk mitigation measures. Abstract Camera trapping has become an

Landscape‐scale predictions of future grassland conversion to cropland or development

Conservation Biology, Volume 39, Issue 1, February 2025.
Abstract Grassland conservation planning often focuses on high‐risk landscapes, but many grassland conversion models are not designed to optimize conservation planning because they lack multidimensional risk assessments and are misaligned with ecological and conservation delivery scales.
