Trends of Aboveground Net Primary Productivity of Patagonian Meadows, the Omitted Ecosystem in Desertification Studies Open

Matías Curcio, J. Gonzalo N. Irisarri, Guillermo Garcia Martínez, Martı́n Oesterheld · 2023

The United Nations defines desertification as the loss of productivity in arid and semiarid environments. The extended steppes of Patagonia harbor small meadows whose compounded area is comparatively small, but their aboveground net primar…

Grazers and fires: Their role in shaping the structure and functioning of the Río de la Plata Grasslands Open

José M. Paruelo, Martı́n Oesterheld, Alice Altesor, Gervasio Piñeiro, Claudia Rodríguez , et al. · 2022

The Río de la Plata Grasslands (RPG) are one of the largest areas of open ecosystems (grasslands, shrublands and savannas) in the world. Historically, these systems have experienced, and continue to experience, an enormous loss of natural …

Trends in ANPP Response to Temperature in Wetland Meadows across a Subcontinental Gradient in Patagonia Open

J. Gonzalo N. Irisarri, Pablo A. Cipriotti, Marcos Texeira, Matías Curcio · 2022

Due to ongoing global warming, seasonal patterns of aboveground net primary production (ANPP) may be altered by temperature trends. Of particular interest is the seasonal association between ANPP and temperature at the beginning of the gro…

Stocking rate and marketing dates for yearling steers grazing rangelands: Can producers do things differently to increase economic net benefits? Open

Tevyn Baldwin, John P. Ritten, Justin Derner, David J. Augustine, Hailey Wilmer , et al. · 2022

The combination of stocking rate and marketing date that maximizes average net return per head will not necessarily maximize average net return per hectare. The combination of stocking rate and marketing date that maximizes average net ret…
