Predicting how seed-eating passerines respond to cattle grazing in a semi-arid grassland using seed preferences and diet
(Elsevier Science, 2020-02)
Numerical responses of animals to habitat perturbation often seem inconsistent, spreading skepticism about the predictive capacity of applied ecology. Domestic grazing changes several habitat variables that can affect ...
Propriedades físicas, mecânicas e hídricas de um argissolo submetido ao pastejo de ovinos em campo nativo
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2012-05-28)
The natural pastures characterize important food source for the creation of cattle and sheep.
These often are subjected to intensive grazing schemes, which may result in physical
deterioration of the soil. Sustainable ...
Correlações entre características morfogênicas e estruturais em pastos de capim-braquiária
(2012-01-01)
The analysis of both morphogenetic and structural characteristics of pasture allows us to understand the response patterns of the plant to the environment. Thus, this study was conducted to evaluate the associations between ...

Grass recruitment constraints along a grazing gradient in Patagonia: N-limitation x adult competition trade-off
(Elsevier, 2021-03-09)
We explored the effect of N addition and adult canopy competition on the recruitment of lost preferred species in the Patagonian steppe, where a decelerated N cycling scenario (sensu Ritchie et al., 1998) had been previously ...
Patrones de distribución espacial de ovinos en sistemas ganaderos extensivos de Patagonia Sur
(Facultad de Agronomía, Universidad de Buenos Aires, 2020-09-30)
La producción ovina en Patagonia Sur se realiza sobre extensos cuadros de 1000 a más de 5000 ha. En ese contexto, los animales seleccionan libremente los sitios de pastoreo generando a veces áreas sobrepastoreadas y ...
Influence of Forage Diversity and Condensed Tannins on Livestock Foraging Behavior, Production and Environmental Impact
(Utah State University, 2020-08)
Eating a combination of forages with different chemistries (i.e., nutrients, beneficial compounds such as tannins) may enhance ruminant nutrition and reduce environmental impacts relative to eating single forages. I explored ...
Aridity and grazing as convergent selective forces: An experiment with an Arid Chaco bunchgrass
(Ecological Society of America, 2010-10)
It has been proposed that aridity and grazing are convergent selective forces: each one selects for traits conferring resistance to both. However, this conceptual model has not yet been experimentally validated. The aim ...
