Differential responses of soil microorganisms to precipitation changes in austral semiarid grasslands
Toledo, Santiago; Gargaglione, Veronica Beatriz; Yahdjian, Laura; Peri, Pablo Luis (Elsevier, 2023-06)Global climate models predict that precipitation regimes will change, generating great impacts on various ecosystem processes and functions. Therefore, it is important to know how drought and precipitation increases would ... -
Effect of defoliation frequency on Rytidosperma virescens plants and arbuscular mycorrhizal fungi colonization
Toledo, Santiago; Fontenla, Sonia Beatriz; Peri, Pablo Luis (Elsevier, 2022-06-09)Rangelands provide different ecosystem services to satisfy human needs. Although grazing management in southern Patagonia is mostly characterized by extensive continuous grazing, rotational grazing management may improve ... -
Environmental Conditions and Grazing Exerted Effects on Arbuscular Mycorrhizal in Plants at Southern Patagonia Rangelands
Toledo, Santiago; Peri, Pablo Luis; Fontenla, Sonia Beatriz (Elsevier, 2022-03)Arbuscular mycorrhizal (AM) fungi play a major role in maintaining ecosystem functions. AM fungi are found in most ecosystems including rangelands currently under increasing pressures from human activities. Southern Patagonia ... -
Mineral fertilization impacts microbial activity and endophytic fungi but not microbial biomass in semiarid grasslands
Toledo, Santiago; Gargaglione, Veronica Beatriz; Peri, Pablo Luis (Elsevier, 2024-01)Applications of mineral fertilizer to grasslands have become more frequent in recent decades to increase forage production. However, the impacts of mineral fertilizer on the soil microbiome is poorly understood in cold ... -
Silvopastoral use of Nothofagus antarctica forests in Patagonia: impact on soil microorganisms
Gargaglione, Veronica Beatriz; Gonzalez-Polo, Marina; Birgi, Jorge Alberto; Toledo, Santiago; Peri, Pablo Luis (Springer, 2022-09-06)Soil microorganisms contribute to soil carbon storage, soil respiration and nutrient cycling. In south Patagonia, there are scarce studies on carbon (C) and nitrogen (N) in soil microbial biomass (MB). The aim of this work ... -
Structure and function of soil microbial communities in fertile islands in austral drylands
Toledo, Santiago; Peri, Pablo Luis; Correa, Olga S.; Montecchia, Marcela Susana; Gargaglione, Veronica Beatriz; Ladd, Brenton (Wiley, 2022-04-15)Fertile islands are an important determinant of ecosystem functioning in drylands. These resourcerich patches are maintained by complex interactions among biotic and abiotic factors. Soil microorganisms are responsible for ...
