Linking effect traits of soil fauna to processes of organic matter transformation
(Wiley, 2024-12)Soil organic matter (SOM) transformation processes are regulated by the activities of plants, microbes, and fauna. Compared with plants and microbes, effects of soil fauna are less understood because of their high taxonomic ... -
Assessing the potential impact of grasshopper outbreaks on Patagonian wetlands through mathematical modelling
(Springer Nature, 2025-01)Herbivorous insects occasionally produce population outbreaks that can alter the availability of food resources for other animals and cause economical losses. In the Patagonian steppe, wetlands are important ecosystems due ... -
Soil food-web energy fluxes reveal diverse responses to smallholder land-use choices in temperate forests
(Elsevier, 2025-01)The consequences of land-use change for soil fauna communities and soil functionality are hard to quantify and poorly understood. Energy fluxes provide a quantitative framework to link soil food webs to ecosystem functions. ... -
Dual identity: the ecology and behaviour of the robber fly Mallophora ruficauda, a pest of honeybees and parasitoid of Scarab beetles
(Schweizerbart Science Publishers, 2024-12)Mallophora ruficauda is a dipteran ectoparasitoid and insect predator native to South America, that as an adult feeds mainly on foraging honeybees. Under suitable conditions, population outbreaks can detrimentally impact ... -
Regional adaptation of integrated pest management to control invasive forest insects
(Wiley, 2024-12)Globalization is increasing the threat of invasive forest insects to ecosystems. Control efforts against the same pest species progressively occur across distant jurisdictions as integrated pest management (IPM) programs ... -
Seguimiento de parámetros productivos de una parcela experimental de Festuca pallescens
(Facultad de Ciencias Agrarias, Universidad Nacional del Comahue, 2024-06)Este proyecto se enmarca dentro del Convenio de cooperación técnica entre la Facultad de Ciencias Agrarias de la Universidad Nacional del Comahue y el Instituto Nacional de Tecnología Agropecuaria (Res. FAC N° 2022-056, ... -
Peso vivo promedio de terneros de destete, homogeneidad de lote y sus efectos sobre el precio final de venta en la localidad de Guañacos
(Facultad de Ciencias Agrarias, Universidad Nacional del Comahue, 2024-12)La crisis climática actual sumada al deterioro de los pastizales naturales obliga a los actores sociales vinculados con la producción bovina a tomar acciones de buenas prácticas ganaderas que garanticen la conservación y ... -
Estrés en la esquila ovina = Stress in sheep shearing
(Facultad de Ciencias Veterinarias, Universidad Nacional del Litoral, 2024-10)La esquila representa un estrés agudo para los animales, se ha descripto la respuesta al estrés de las ovejas durante la esquila, pero hay información limitada sobre qué factores desencadenan esta respuesta. Con el método ... -
Are they even there? How agri-environment schemes investments reach their target species in Dutch dairy-farmland, the case of meadow birds
(Elsevier, 2024-12)Agri-environmental schemes (AES) implemented by farmer collectives for meadow bird protection in The Netherlands create complex landscape mosaics due to the variability of options and combinations farmers use. We propose ... -
Effect of Grasses on Native Tree Seedling Establishment Along a Water Stress Gradient: Results of Forest and Greenhouse Experiments
(Wiley, 2024-11)Anthropogenic activities such as cattle grazing and forest clearing have led to the establishment of early successional grass layers in some native forests, which may inhibit or entirely prevent native tree regeneration. ... -
Site conditions shaped the effect of silvicultural management on the biodiversity of ectomycorrhizal fungi in mixed Nothofagus forests
(Elsevier, 2024-07)Ectomycorrhizas (EcM) constitute a crucial component of soil biota in forest ecosystems, where they perform functions of great ecological significance. Although there is available information about the individual effects ... -
A New Framework for Vegetation Productivity Dynamics Assessment in Patagonia: Rangeland Functional Archetypes
