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.

Wildlife Monographs, EarlyView.
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

Rendimiento de cultivos de guisantes en diferentes suelos agrícolas

, 2023
The yield of pea plants (Pisum sativum cv. Lincoln) grown on 9 different soils of Granada has been studied to know the effectivity of the symbiosis established between native Rhizobium leguminosarum and the cultivar assayed. Results obtained have show high differences between the yields of plants grown in each of the soil assayed probably due to the ...

Artificial exposure to herbivore‐induced volatile organic compounds reduces herbivory and modulates gene expression in potato plants

Journal of Applied Ecology, Volume 63, Issue 8, August 2026.
These findings provide strong mechanistic evidence for VOCs mediating pest resistance and suggest that exposure to herbivore‐induced, plant‐derived VOCs can enhance pest resistance in potato crops. These results might offer novel information for developing ecologically sustainable plant volatile‐based strategies for boosting protection against pests in

Rompiendo el techo de rendimiento del cultivo de arroz.

, 2022
En 2012 se conformó un equipo de trabajo interinstitucional INIA-ACA-GMA con el fin de buscar respuestas a la preocupante tendencia a estabilización de los rendimientos nacionalesdel arroz, en el entorno de los 8 t/ha, que hacía presumir una aproximación al techo productivo. De esta iniciativa surgió un proyecto cofinanciado por ANII, INIA, GMA, COOPAR

Sugar provisioning increases parasitoid numbers in agroecosystems but may not reduce pest densities: A meta‐analysis

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our findings demonstrate that providing sugar sources reliably supports parasitoid populations and parasitism rate but does not systematically translate into improved pest suppression or yield gains. These results suggest that, for economic and practical reasons, sugar inputs at the edge of cultivated fields should be favoured.

Efficiency of Spatial Subsidies Under Information Constraints: A Case Study

Agricultural Economics, Volume 57, Issue 3, May 2026.
ABSTRACT This study compares the efficiency of homogeneous versus spatially heterogeneous subsidies in developing agricultural plans compatible with bird sustainability. Using the plains of Lleida as a case study—where incentives for agricultural intensification threaten a bird community‐we employ a spatially explicit model that simulates crop yields ...

Landscape and crop diversity contributes to greater yield stability

Journal of Applied Ecology, Volume 62, Issue 11, Page 3092-3104, November 2025.
These findings underscore the importance of promoting crop diversity and maintaining heterogeneous agricultural landscapes, particularly in pollinator‐dependent crops. Promoting diverse agricultural landscapes with balanced heterogeneity can enhance the resilience of agricultural systems to climate change and contribute to long‐term food security ...

Effect of a ceruminolytic ear cleaner on clinical, microbiological and ear canal microbiome evolution in canine erythemato‐ceruminous otitis externa associated with proliferation of Malassezia yeasts

Veterinary Dermatology, Volume 36, Issue 5, Page 668-678, October 2025.
Background – Erythemato‐ceruminous otitis externa (ECOE) is commonly associated with Malassezia spp. and microbial imbalance. Hypothesis/Objective – To assess the clinical performance of an ear cleaner in dogs suffering from ECOE associated with Malassezia spp. overgrowth and to measure its impact on the microbiota. Conclusions and Clinical Relevance –
