Grazing time and milk production of crossbred cows in a rotational area of Elephant grass and Tanzania grass
(2004-11-01)
This study was carried out in January of two consecutive years. The objective was to evaluate the grazing time, the grazing rate and the milk production of crossbred cows, managed in two rotational grazing areas, one with ...
Changes in vegetation structure induced by domestic grazing in Patagonia (Southern Argentina)
(Academic Press Ltd - Elsevier Science Ltd, 2011-11)
We analyzed the structural differences associated with grazing exclusion on vegetation by studying 24 grazed-ungrazed paired sites in Patagonia (Argentina). Our objectives were to evaluate the effect of grazing on plant ...
Diet of a fossorial rodent (Octodontidae), above-ground food availability, and changes related to cattle grazing in the Central Monte (Argentina)
(Academic Press Ltd - Elsevier Science Ltd, 2009-03)
Overgrazing by livestock has caused desertification in the Monte, where ctenomyids and livestock share grasses as main food items. The diet of Ctenomys eremophilus, above-ground food availability and changes related to ...
Soil microbial communities respond to an environmental gradient of grazing intensity in south Patagonia Argentina
(Elsevier, 2020)
Soil microorganisms communities regulate key functions in terrestrial ecosystems and contributes to the formation of stable organic matter and hence climate change mitigation. The structure, diversity and activity of soil ...
NITROGEN SOIL BUDGETS IN CONTRASTING DAIRY GRAZING SYSTEMS OF SOUTHERN CHILE, A SHORT-TERM STUDY
(Sociedad Chilena de la Ciencia del Suelo, 2010)
Experimental evidence for crustacean zooplankton grazing activity on mixotrophic ciliates
(BRILL ACADEMIC PUBLISHERS, 2019)
Abundance and spatial patterning of coexisting perennial grasses in grazed shrublands of the Patagonian Monte
(Academic Press Ltd - Elsevier Science Ltd, 2007-07)
We analysed the density, bunch size, and spatial patterning in relation to the shrubby matrix of the three dominant perennial grasses of the Patagonian Monte with different functional traits related to resource ...
Grazing impact on structure and dynamics of bare soil areas in a Patagonian grass-shrub steppe
(Academic Press Ltd - Elsevier Science Ltd, 2020-08)
Bare soil is an idiosyncratic and important feature of arid ecosystems that can be affected by human land use such as domestic grazing intensification. Here we focused on the study of individual bare soil areas (BSA) and ...
Drivers assessment of zooplankton grazing on phytoplankton under different scenarios of fish predation and turbidity in an in situ mesocosm experiment
(Springer, 2021-01-07)
Zooplankton play a key role in energy transfer within lake food webs, but we have a poor knowledge concerning their role as phytoplankton grazers in shallow subtropical lakes. In this study, we aimed to determine how ...
Environmental and grazing influence on spatial variability of intertidal biofilm on subtropical rocky shores
(INTER-RESEARCH, 2011)
Epilithic biofilm on rocky shores is regulated by physico-chemical and biological factors and is important as a source of food for benthic organisms. The influences of environmental and grazing pressure on spatial variability ...
