Forest edges buffer effects of agricultural management on bee–plant interaction networks

open access: yesEcological Entomology, EarlyView.
Agricultural management effects: Organic and conventional crop margins host similar bee and plant species, but network structure differs: organic farms exhibit higher interaction diversity, conventional farms higher connectance. Role of forest edges: Native forest edges stabilize bee–plant networks by providing continuous floral resources and suitable ...

Addressing the Right to Food Through Food Expenditure Burdens: Distributional Evidence Among Low‐Income Farming Families in Brazil (2012–2023)

open access: yesWorld Food Policy, Volume 12, Issue 2, November 2026.
ABSTRACT Household food expenditure continues to be a key factor in ensuring the realization of the Human Right to Adequate Food. Particularly in Brazil, access to food can be limited by economic constraints in vulnerable families, especially among farming families, who have been more vulnerable to food insecurity in recent years in the country.

Distribución del tamaño de partícula por dispersión dinámica de luz de la tetracarboxifenilporfirina de cobre (II) anclada al dióxido de titanio

open access: yesIteckne, 2014
La sensibilización del dióxido de titanio con porfirinas es esencial para la generación de especies reactivas del oxígeno inducida con luz visible. Sin embargo, estos sensibilizadores tienden a lixiviarse en el medio de reacción.

A synthetic eco‐evolutionary proposal for the conservation of wild relatives of the olive tree

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1904-1924, September 2026.
Societal Impact Statement Crop wild relatives (CWR) are valuable sources of genetic diversity for plant breeding. However, the identification of wild untapped genetic resources (i.e., unexploited in crops) is not always straightforward. We propose a methodology to guide the identification and conservation of these resources that integrates both genetic

Ecology of declining populations of gray foxes (Urocyon cinereoargenteus) in Indiana, USA Ecología de las poblaciones en declive de zorros grises (Urocyon cinereoargenteus) en Indiana, EE.UU.

open access: yesWildlife Monographs, Volume 226, Issue 1, September 2026.
We estimated seasonal space use, cover selection, and resource selection; evaluated gene flow and potential genetic barriers; and assessed cause‐specific survival rates and reproduction of radiomarked gray foxes in Indiana, USA. Our results provide evidence that gray foxes in Indiana are an edge species with relatively large home ranges, relatively low

Maximum water stress is decoupled from climate, traits, and growth in a xeric oak

open access: yesNew Phytologist, Volume 251, Issue 5, Page 2392-2406, September 2026.
We sampled sites across the geographic distribution of blue oak (Quercus douglasii) in California, USA, which spans a large range of mean annual precipitation. Summary Our ability to explain and predict the spatial patterns of forest mortality remains limited.

Diseño de un sistema piloto para el estudio de la corrosión del material de tubería y su contribución en el deterioro de la calidad del agua potable

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2008
Los sistemas de distribución pueden afectar la calidad del agua potable debido a las condiciones de la tubería y a la operación del sistema. Algunos parámetros son sensibles a la variación durante la distribución como: el cloro residual, pH, color y ...

Water security from Indigenous knowledge perspective: A scoping review

open access: yesPeople and Nature, Volume 8, Issue 8, Page 2668-2681, August 2026.
Abstract Water security is a growing field of research in water resources management and has been increasingly examined from the perspectives of Indigenous knowledge. This study presents a scoping review that explores how Indigenous knowledge perspectives on water security are represented in the scientific literature.

Ecology of reintroduced Rocky Mountain bighorn sheep in Dinosaur National Monument La Ecología de Borrego Cimarron de las Montañas Rocosas Reintroducido en el Monumento Nacional de Dinosaurio

open access: yesWildlife Monographs, Volume 223, Issue 1, August 2026.
We synthesized GPS telemetry, genetic, and pathogen data to evaluate metapopulation processes in a reintroduced Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population in Dinosaur National Monument. We estimated subpopulation‐specific abundances and found 4 small subpopulations with high genetic diversity, partial connectivity, and ...
