A functional classification of 63 common Poaceae in the “Campos” grasslands of South America
Cruz, Pablo; Lezana, Lucrecia; Durante, Martin; Jaurena, Martín; Figari, Mercedes; Oliveira, Leandro Bittencourt de; Theau, Jean-Pierre; Massa, Ernesto Segundo; Viegas, Julio; Quadros, Fernando L. Ferreira de (Asociación Argentina de Ecología, 2019-08)The natural grasslands that form part of the “Campos” of South America contain a large number of species at the paddock level (high α diversity), but little differentiation among paddocks (low β diversity). Thus, forage ... -
A fungal endophyte of a palatable grass affects preference of large herbivores
Hernández Agramonte, Ignacio M.; Semmartin, María Gisela; Omacini, Marina; Durante, Martin; Gundel, Pedro Emilio; De Battista, Jose Pedro (2018-04)Temperate grasses frequently acquire resistance to herbivores through a symbiosis with epichloid fungi that produces alkaloids of variable deterrent effects. However, in those cases without apparent endophyte negative ... -
A MODIS based tool to assess inundation patterns: an example for the Paraná Delta River
Durante, Martin; Di Bella, Carlos Marcelo (Gerencia de Comunicación e Imagen Institucional, DG-SICyP, INTA, 2020-04)Wetlands are one of the most productive yet altered ecosystems due to human activities across the world. They rely largely on their water flow to provide several ecosystem functions. Then, to develop a land use plan that ... -
Beef Cattle Grazing Native Grasslands May Follow Three Different Supplement Response Patterns
Cazzuli, Fiorella; Durante, Martin; Hirigoyen, Andrés; Sánchez, Javier; Rovira, Pablo; Beretta, Virginia; Simeone, Alvaro; Jaurena, Martín; Savian, Jean Víctor; Poppi, Dennis; Montossi, Fabio; Lagomarsino, Ximena; Luzardo, Santiago; Brito, Gustavo; Velazco, José Ignacio; Lattanzi, Fernando Alfredo; Bremm, Carolina (MDPI, 2023-08-07)Previous studies on winter supplementation of growing cattle grazing stockpiled native Campos grasslands suggest that forage allowance (FA), herbage mass, and weather conditions before and during the supplementation period ... -
Comparación de índices climáticos y espectrales en la estimación de rendimiento de maíz y soja a nivel departamental en Entre Ríos
Vaiman, Nicolas (Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2018-09)Las estimaciones de rendimientos agrícolas son de gran importancia debido a que la producción de alimentos juega un papel fundamental en la seguridad alimentaria y en la economía de los países. En el pasado, las estimaciones ... -
Estimación de las precipitaciones mediante interpolación vs. datos satélites para Entre Ríos (Argentina)
Vaiman, Nicolas; Durante, Martin (2016)Para estimar precipitaciones en lugares sin estaciones meteorológicas se suele recurrir a distintos métodos de interpolación de datos obtenidos en estaciones cercanas. Sin embargo, otra alternativa es utilizar estimaciones ... -
Estimating overnight weight loss of corralled yearling steers in semiarid rangeland
Durante, Martin; Irisarri, Jorge Gonzalo Nicolás; Derner, Justin D.; Reeves, Justin L.; Mortenson, Matthew C.; West, Mark (2016)A common practice for assessing livestock weight gains from grazing animals on rangelands is to confine animals overnight without feed or water to reduce variation in weight loss and percent shrink. Advances in remote ... -
How Long Should Grasses of South American Campos Grasslands Rest for Stockpiling Forage?
Risso Barbosa, Marlon; Durante, Martin; Marin, Luciana; Cazzuli, Fiorella; Quadros, Fernando Luiz Ferreira de; Dixon, Rob M.; Correa, Franklin Riet; Jaurena, Martín (MDPI, 2024-08)Stockpiling forage (i.e., deferring grazing) is one way to provide forage for livestock during intervals of low pasture growth, but there are trade-offs as nutrient content declines with increasing forage maturity. Phosphorous ... -
Informe Forrajero - Otoño 2017
Vasallo, María Mercedes; Oyarzabal, Mariano; Durante, Martin; Blanco, Lisandro Javier (Instituto Nacional de Tecnología Agropecuaria (INTA), 2017)El presente informe contempla la situación forrajera a nivel nacional. Ha sido elaborado por el Proyecto “PID-2013-0051: Diagnóstico, planificación, seguimiento y prospección forrajera en sistemas ganaderos”. -
Modelos explicativos y predictivos de la productividad, disponibilidad y calidad de forraje basados en sensores remotos
Durante, Martin (Facultad de Agronomía, Universidad de Buenos Aires, 2013)La productividad primaria neta aérea (PPNA) y la biomasa y la calidad forrajeras son clave en los sistemas pastoriles. Dada su variación espacial y temporal, contar con descripciones de dicha variación y con herramientas ... -
Primary production of lowland natural grasslands and upland sown pastures across a narrow climatic gradient
Durante, Martin; Piñeiro, Gervasio; Oesterheld, Martin; Irisarri, Jorge Gonzalo Nicolás (2017-04)Variation in aboveground net primary production (ANPP) is usually studied across wide environmental gradients focusing on spatial averages of zonal natural communities. We studied the spatial and temporal variation of ANPP ... -
Red nacional de monitoreo de pastizales naturales de Argentina: productividad forrajera de la vegetación extrapampeana
Blanco, Lisandro Javier; Durante, Martin; Ferrante, Daniela; Quiroga, Raul Emiliano; Demaria, Manuel Rodolfo; Di Bella, Carlos Marcelo (Ediciones INTA, 2019-04)Las regiones extrapampeanas sostienen una porción relevante de la producción ganadera de Argentina (bovinos, caprinos, ovinos y camélidos), sustentada principalmente por el aporte forrajero de la vegetación nativa. En este ... -
Remotely Sensed Spatiotemporal Variation in Crude Protein of Shortgrass Steppe Forage
Irisarri, Jorge Gonzalo Nicolás; Durante, Martin; Derner, Justin D.; Oesterheld, Martin; Augustine, David J. (MDPI, 2022-02)In the Great Plains of central North America, sustainable livestock production is dependent on matching the timing of forage availability and quality with animal intake demands. Advances in remote sensing technology provide ... -
Using APAR to Predict Aboveground Plant Productivity in Semi-Arid Rangelands: Spatial and Temporal Relationships Differ
Gaffney, Rowan; Porensky, Lauren M.; Feng, Gao; Irisarri, Jorge Gonzalo Nicolás; Durante, Martin; Derner, Justin D.; Augustine, David J. (2018)Monitoring of aboveground net primary production (ANPP) is critical for effective management of rangeland ecosystems but is problematic due to the vast extent of rangelands globally, and the high costs of ground-based ... -
What Factors Control the Crude Protein Content Variation of a Basaltic “Campos” Native Grassland of South America?
Núñez, Laura; Hirigoyen, Andrés; Durante, Martin; Arroyo, José María; Cazzuli, Fiorella; Bremm, Carolina; Jaurena, Martín (MDPI, 2022-08)Native grasslands are the main source of food for livestock in the Campos region of South America.
