Invasions: the trail behind, the path ahead, and a test of a disturbing idea
(Wiley, 2012-01)We provide a brief overview of progress in our understanding of introduced plant species. Three main conclusions emerge from our review: (i) Many lines of research, including the search for traits that make species good ... -
Investigación socio-ecológica a largo plazo en la Patagonia Austral: Estrategias interdisciplinarias para lograr la conservación de los recursos naturales a través de un manejo sustentable bajo escenarios de cambio global
(2016-04)Las dimensiones ecológicas, sociales, institucionales y políticas de los problemas ambientales abarcan escalas espaciales y temporales que exceden a la mayoría de las investigaciones científicas. Una alternativa que crece ... -
Isotope geochemistry as a natural tag of fish in Patagonian freshwater environments: the invasive Chinook salmon case
(Elsevier, 2023-05-15)Patagonian aquatic environments have been invaded since the end of the last century by different species of salmonids.Knowing the natal origin and homing/straying rate of the salmonids in colonised environments is essential ... -
Isotopic evidence for oligotrophication of terrestrial ecosystems
(Springer Nature, 2018)Human societies depend on an Earth system that operates within a constrained range of nutrient availability, yet the recent trajectory of terrestrial nitrogen (N) availability is uncertain. Examining patterns of foliar N ... -
Knowledge arising from long-term research of variable retention harvesting in Tierra del Fuego: where do we go from here?
(Springer Open, 2019-07)Nothofagus pumilio forests in Tierra del Fuego are the southernmost forests in the world, where extreme climate conditions represent a challenge to attain sustainable forest management. Retention forestry was proposed as ... -
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. ... -
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 ... -
Landscape variables influence over active restoration strategies of Nothofagus forests degraded by invasive Castor canadensis in Tierra del Fuego
(MDPI, 2021-07-06)North American beavers (Castor canadensis) are responsible for the major changes in the Tierra del Fuego Archipelago, altering riparian forests for the long-term. Passive restoration of the areas affected was ineffective ... -
Leaf nutrients, not specific leaf area, are consistent indicators of elevated nutrient inputs
(Nature Research, 2019)Leaf traits are frequently measured in ecology to provide a ‘common currency’ for predicting how anthropogenic pressures impact ecosystem function. Here, we test whether leaf traits consistently respond to experimental ... -
Leaf wettability, anatomy and ultra-structure of Nothofagus antarctica and N. betuloides grown under a CO2 enriched atmosphere
(Elsevier, 2023-01)Increasing CO2 air concentration may affect wettability, anatomy and ultra-structure of leaves of Patagonian forest species, evergreen and deciduous plants potentially responding differently to such CO2 increases. In this ... -
Linking changes in species composition and biomass in a globally distributed grassland experiment
(Wiley, 2022-11-24)Global change drivers, such as anthropogenic nutrient inputs, are increasing globally. Nutrient deposition simultaneously alters plant biodiversity, species composition and ecosystem processes like aboveground biomass ... -
Linking potential biodiversity and three ecosystem services in silvopastoral managed forest landscapes of Tierra del Fuego, Argentina
(Taylor & Francis, 2017-04)Several studies confirm that biodiversity loss endangers ecosystem services (ES) supply and human well-being. A better understanding of biodiversity–ES relationships and effects of biodiversity loss on ES supply is needed. ... -
Linking species distribution and territorial planning to the management of the endangered Gonopterodendron sarmientoi in native forests of the Chaco region, Argentina
(Elsevier, 2022-06-11)For management and conservation strategies in the long term is necessary to know the species distribution and main biophysical aspects that determine the structure and dynamics of the forest. The aim of this work was to ... -
Litter decomposition and nutrients dynamics in Nothofagus antarctica forests under silvopastoral use in Southern Patagonia.
(Springer, 2012-01-24)The role of environmental variables on litter decomposition and its nutrient release in Nothofagus antarctica forest in Patagonia is poorly understood. Moreover, in these forests under silvopastoral use there are few ... -
Litterfall and nutrients return in Nothofagus antarctica forests growing in a site quality gradient with different management uses in Southern Patagonia
(2015-01)We evaluated the annual litterfall and nutrients return in primary forests of Nothofagus antarctica growing at three different site classes (SC) (III, IV and V) and compared two of these forests with adjacent stands under ... -
Long-term monitoring of thinning for silvopastoral purposes in Nothofagus antarctica forests of Tierra del Fuego, Argentina
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria, España, 2018)Aim of the study: To analyse the effectiveness of thinning on tree growth, forest structure and microclimatic variables along seven years after cuttings in a secondary Nothofagus antarctica forest in Southern Patagonia. Area ... -
Manejo de Bosques con Ganadería Integrada (MBGI) en Argentina
(INIA (Uruguay), 2022-01)La mayor parte de los bosques nativos en Argentina cuentan con ganadería. En este contexto, en 2015 se firma el Convenio Marco Interinstitucional entre los actuales Ministerios de Agroindustria y el de Ambiente y Desarrollo ... -
Masting has different effects on seed predation by insects and birds in antarctic beech forests with no influence of forest management
(2017-09-15)Mast seeding is characteristic of many long-lived tree species and widely proposed as a mechanism to reduce seed predation. However, whether the efficiency of this reproductive response may vary depending on type of seed ... -
MASTREE+: Time-series of plant reproductive effort from six continents
(Wiley, 2022-04-01)Significant gaps remain in understanding the response of plant reproduction to environmental change. This is partly because measuring reproduction in long-lived plants requires direct observation over many years and such ...
