Importance and spatial patterns of invisible fisheries in Amazonian clear‐water rivers as revealed by fisher knowledge and collaboration

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
The graphical abstract highlights the research collaboration with fishers through interviews to record fishers' knowledge and participatory monitoring, to provide data on small‐scale fisheries in three clear water rivers (Trombetas, Tapajos and Tocantins).

Successional and native forests predict the occurrence and infection status of Chagas disease vectors in Panama

open access: yesJournal of Applied Ecology, Volume 63, Issue 1, January 2026.
Findings here show that successional forest predicts greater kissing bug infestation risk in palm trees, whereas native forest predicts lower kissing bug occurrence but greater infection with T. cruzi. These insights can guide land use planning towards vegetation management practices that help minimize T. cruzi transmission risks for rural communities.

Grazing and climate interact to regulate greening trends in Mediterranean grasslands

open access: yesJournal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our results show that traditional grazing systems can maintain grassland stability without causing degradation, but they can also increase the ecosystem's vulnerability to climate change. We provide clear evidence that GPS‐based livestock monitoring is a powerful and scalable tool for sustainable rangeland management.

Compost amendments up to one inch restore dry rangeland soil health

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1324-1333, September 2025.
Rangelands harbor immense diversity and provide ecosystem services across vast swaths of land while supporting rural economies and the food system, but degraded rangelands may require active management to restore diversity and function. We added varying amounts of compost to understand if there are linear or saturating effects on vegetation and soil ...

Natural variation of response to glyphosate in Sinapis alba (Brassicaceae): Physiological effects, shikimate accumulation and genetic mechanisms

open access: yesWeed Research, Volume 65, Issue 5, September/October 2025.
Abstract Glyphosate is the most widely used herbicide worldwide, and glyphosate‐resistant weeds have increased globally. Resistance mechanisms, including target‐site resistance (TSR) and non‐target‐site resistance (NTSR), are well documented, but their extent and importance are poorly understood among biotypes. This study examines the natural variation

Linealización entrada/salida de sistemas no lineales afines utilizando un filtro

open access: yesIngeniería e Investigación, 2000
La linealización Entrada/Salida (E/S), dentro del marco teórico del control geométrico, es una técnica madura para sistemas no lineales afines. Esta técnica cancela los términos no lineales de la planta, usando una retroalimentación de estado no lineal ...
