Lamb and wool provisioning ecosystem services in Southern Patagonia
(MDPI, 2021-07-30)In Southern Patagonia, grasslands are the principal food resource for sheep reared for meat and wool as the main provisioning ecosystem services (ES). The main objective of this study was to model lamb and wool production ... -
Land sharing in South Patagonia: Conservation of above-ground beetle diversity in forests and non-forest ecosystems
(Elsevier, 2019-11)Land-sharing strategies, as variable retention silvicultural proposals, are useful to mitigate harmful effects of economic activities on forest biodiversity; benefits have been reported worldwide for several organisms. ... -
Land tenancy, soybean, actors and transformations in the pampas: A district balance
(2015-06)In Argentina, the recent expansion of agriculture has turned into an extreme process almost completely dominated by soybean. The magnitude and speed of soybean expansion are believed to be the main drivers behind social, ... -
Land use intensity and cropping sequence effects on aggregate stability and C storage in a Vertisol and a Mollisol
(2013)The relevant change in land use duemainly to the rapid expansion of soybean cropping towards areas traditionally occupied for livestock purposes or with native grasslands of South America may have negative consequences on ... -
Land-use change affects soil hydro-physical properties in Mollisols of semiarid Central Argentina
(Elsevier, 2021-06-01)The objective of the present study was to describe the relationships between soil physical properties and to identify variables that determine the pore system and hydrological functions which are specifically important in ... -
Landholders’ perceptions on legal reserves and agricultural intensification: Diversity and implications for forest conservation in the eastern Brazilian Amazon
(Elsevier, 2021)Forest conservation on privately owned lands is a cornerstone of the Brazilian environmental policy framework. Brazilian legislation requires that all farms in the country maintain and protect forest areas known as Legal ... -
Landscape configuration modulates the presence of leaf-cutting ants in eucalypt plantations
(Springer Nature, 2023-08)Pest responses to landscape complexity show variable patterns globally, primarily related to species traits and specific managed habitats. Leaf-cutting ants (LCAs) are native insects and important pests of plantation forests ... -
Landscape heterogeneity influences on sheep habits under extensive grazing management in Southern Patagonia
(2015)In Southern Patagonia, continuous grazing with fixed stocking rates in large paddocks prevails over grazing systems subjected to regular evaluations and rotational rests. Because of this, sheep extensive systems need ... -
