Ungulate prey availability to inform Mexican wolf recovery within its historical range

The Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
We estimated the potential ecological carrying capacity for the Mexican wolf based exclusively on ungulate prey biomass estimated from camera trap surveys. In the United States, the potential density estimate is high (21.4–52.7 wolves/1,000 km2) owing to the presence and relatively high densities of elk, mule deer, and white‐tailed deer.

Drying suppresses fine root production to 1 m depths and alters root traits in four distinct tropical forests

New Phytologist, Volume 249, Issue 4, Page 1992-2009, February 2026.
Summary Drying and drought in tropical forests, which have some of the highest net primary productivity on Earth, are likely to alter root dynamics, ecosystem function, and carbon (C) storage. We used a chronic drying experiment in four lowland Panamanian forests to investigate whether soil drying shifts tropical forest root production from surface to ...

Forest bird diversity increases with fragmentation per se in landscapes following forest gains

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our results suggest that, at least for forest breeding birds, the benefits of habitat restoration to increase total forest area could be enhanced by distributing a given amount of restored habitat across multiple patches. Our study also highlights the overarching importance of habitat amount for biodiversity conservation. Taken together, these findings

The Many Pathways of Mining Impacts on Biodiversity

Conservation Letters, Volume 19, Issue 1, January/February 2026.
ABSTRACT Mining is a significant driver of biodiversity loss, with impacts expected to escalate due to rising metal demand for the energy transition. However, global assessments of mining impacts are still in their infancy, as global biodiversity models overlook many relevant impact pathways.

Banco de semillas de gramíneas en fachinales intervenidos mediante rolado selectivo

Semiárida, 2018
El banco de semillas del suelo es la principal reserva de propágulos con que cuenta una comunidad vegetal para su mantenimiento, regeneración y perpetuación. El rolado selectivo puede producir cambios en su composición y distribución.

Cultivating Climate Precarity: Mechanisms of Surplus Capture and Immiserizing Growth in Guatemala's Horticultural Export Sector

Journal of Agrarian Change, Volume 26, Issue 1, January 2026.
ABSTRACT In recent decades, prominent development organizations have promoted market inclusion and agricultural value chain integration as pathways to rural prosperity in the Global South. Focusing upon the experiences of Indigenous Kaqchikel peasants in Guatemala's horticultural export sector, this paper offers a cautionary tale.

Improving Grape Seed Oil Yield Through Optimization of Ultrasound–Microwave Pretreatment and Screw Press Extraction Conditions

Journal of Food Processing and Preservation, Volume 2026, Issue 1, 2026.
Grape seeds are a valuable agroindustrial by‐product, and optimizing oil extraction from them represents an effective approach for both waste valorization and production of high‐quality edible oil. This study investigated the influence of ultrasonic pretreatment duration (0–60 min), microwave exposure time (0–120 s), and screw press speed (11–57 rpm ...
