(Facultad de Agronomía, Universidad Nacional de La Plata, 2023-06)La producción de fruta fina de forma orgánica y/o agroecológica en la Comarca Andina del Paralelo 42º se encuentra con el problema de escasa información local sobre prácticas de manejo de la sanidad de los cultivos, lo que ... -
Functional Traits Mediate the Natural Enemy Response to Land Use at the Local Scale
(MDPI, 2023-05)Arthropods are key nodes for the provision of ecosystem services such as pest control, but their response to land-use change is highly variable depending on the scale of analysis and the natural enemies’ life histories. ... -
Do populations of Festuca pallescens from a rainfall gradient differ in the expression of morpho-physiological traits under drought stress?
(Elsevier, 2023-06)In arid environments, stochastic rainfall and high evapotranspiration force plants to optimize water resources. North Patagonia is characterized by a deep rainfall gradient that gives rise to environments with very contrasting ... -
Forest Health in the Southern Cone of America: State of the Art and Perspectives on Regional Efforts
(MDPI, 2023-04)The plantation and natural forests of South America have been highly impacted by native and exotic pests in recent decades. The interaction of emerging invasive pests, climate change, and timber markets will define the ... -
Relationship between NDVI of Patches and Cover Area of Grasses, Shrubs and Bare Soil Components of a Semi-Arid Steppe from North-West Patagonia, Argentina
(MDPI, 2023-02)Distinguishing the contributions of different vegetation cover such as shrubs and grasses components into the primary production in arid and semi-arid rangelands is a key step to understanding changes at a landscape scale. ... -
Going to scale—From community-based to population-wide genetic improvement and commercialized sheep meat supply in Ethiopia
(Frontiers Media, 2023-03)Community-based breeding programs (CBBPs) have shown, at pilot scale, to be effective and beneficial in achieving genetic progress and in improving livelihoods of smallholder communities. In Ethiopia 134 sheep and goat ... -
Shaping forces modelling genetic variation patterns in the naturally fragmented forests of a South-American Beech
(Elsevier, 2009-10)Fourteen natural populations of the South-American Beech Nothofagus obliqua at the Eastern naturally fragmented area of its distribution range were subjected to genetic analysis using genetic markers. The genetic ... -
Management of Nothofagus genetic resources: Definition of genetic zones based on a combination of nuclear and chloroplast marker data
(Elsevier, 2013-08-15)Development of appropriate forest conservation and management measures for a given tree species includes the identification of distinct genetically homogeneous units across its overall distribution range, which depends on ... -
The effects of Quaternary glaciations in Patagonia as evidenced by chloroplast DNA phylogeography of Southern beech Nothofagus obliqua
(Springer, 2009-03)Climatic oscillations during the Quaternary strongly affected the distribution of warm-temperate tree species, which experienced local restrictions into ice-free areas and posterior expansions. To evaluate the impact of ... -
Predicting poaching hotspots in the largest remnant of the Atlantic Forest by combining passive acoustic monitoring and occupancy models
(Elsevier, 2022-08)Poaching can have major impacts on wild animal populations and is pervasive in tropical regions. The spatial distribution of this furtive activity is particularly difficult to estimate in large natural areas, and this ... -
Worldwide diversity of endophytic fungi and insects associated with dormant tree twigs
(Springer, 2022-03)International trade in plants and climate change are two of the main factors causing damaging tree pests (i.e. fungi and insects) to spread into new areas. To mitigate these risks, a large-scale assessment of tree-associated ... -
Grazing and ecosystem service delivery in global drylands
(American Association for the Advancement of Science, 2022-11-25)Grazing represents the most extensive use of land worldwide. Yet its impacts on ecosystem services remain uncertain because pervasive interactions between grazing pressure, climate, soil properties, and biodiversity may ... -
Latitude, Elevation, and Mean Annual Temperature Predict Peat Organic Matter Chemistry at a Global Scale
(Wiley, 2022-02)Peatlands contain a significant fraction of global soil carbon, but how these reservoirs will respond to the changing climate is still relatively unknown. A global picture of the variations in peat organic matter chemistry ... -
Unravelling negative interactions between humans, mammalian carnivores and raptors in South America
(Asociación Argentina de Ecología, 2022-08)Human-wildlife interactions can be negative when the needs and behavior of wildlife negatively influence human goals, or vice-versa, and management of these interactions may lead to conflict. Here, we review information ... -
Vegetation responses to variations in climate: A combined ordinary differential equation and sequential Monte Carlo estimation approach
(Elsevier, 2023-03)Vegetation responses to variation in climate are a current research priority in the context of accelerated shifts generated by climate change. However, the interactions between environmental and biological factors still ... -
