Foraging niche separation of social wasps in an invaded area: Implications for their management
(Wiley Online Library, 2019-10)Foraging niche separation may be a mechanism to promote coexistence of two competing species by concentrating intraspecific competition relative to interspecific competition. The present study investigated foraging behaviour ... -
Forest active restoration for silvopastoral use in Northwestern Patagonia: relative importance of the nurse effect
(Springer, 2023-03)Ecological interactions, such as facilitation among plant species, has been identified as key for restoration actions. The stress-gradient hypothesis predicts that facilitation increases under harsh environments, but ... -
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 ... -
From farm scale to village scale trade-offs : cereal crop residues use in an agro-pastoral system of the Sudanian zone of Burkina Faso
(2015-03)Traditionally, cereal crop harvest residues are communally grazed by the ruminant herds of villagers and transhumant pastoralists in the agro-pastoral systems which predominate in the savannah zone of West Africa. We ... -
From traditional knowledge to novel adaptations of transhumant pastoralists the in face of new challenges in North Patagonia
(Elsevier, 2018-10)Transhumant pastoralism is a mobile livelihood strategy in many mountainous, arid and semi-arid regions worldwide. The knowledge of pastoral communities and their lifestyle are strongly rooted in the historical evolution ... -
Functional and histopathological changes induced by intraparenchymal injection of kainic acid in the rat cervical spinal cord
(Elsevier, 2015-05)Kainic acid (KA) is an analog of the neurotransmitter glutamate and is widely used as an excitotoxic agent to lesion spinal cord networks, thus, providing an interesting model to learn basic mechanisms of spinal cord injury. ... -
Functional diversity of phytochrome family in the control of light and gibberellin-mediated germination in Arabidopsis
(Wiley, 2014-03)In several species, seed germination is regulated by light in a way that restricts seedling emergence to the environmental conditions that are likely to be favourable for the success of the new individual, and therefore, ... -
Functional farm household typologies through archetypal responses to disturbances
(Elsevier, 2020-02)Methods to construct farm household typologies may differ in their approach but they share a common feature: they rely mostly on structural farm data. Methods to build functional typologies are far less abundant. Households ... -
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. ... -
Ganado y tucuras, ¿afectan la productividad en un campo?
(Ediciones INTA; Estación Experimental Agropecuaria Bariloche, 2023-12)La productividad forrajera permite conocer lo que puede rendir un campo, el nivel de afectación que tiene por los animales que allí se alimentan y pensar estrategias de manejo. En este caso diseñamos e instalamos clausuras ... -
Genetic assessment of the invasion history of Drosophila suzukii in Argentina
(Springer Nature, 2019-08)Drosophila suzukii (Diptera: Drosophilidae) is a highly polyphagous fruit pest native to eastern Asia, which in the last decade had widely expanded its range and become a serious pest in the Americas and Europe. Invasion ... -
Genetic characterization and regional distribution of lymnaeid snails in northern Patagonia, Argentina
(Elsevier, 2023-09)Lymnaeid snails serve as intermediate hosts for Fasciola hepatica (Linnaeus, 1758), the etiological agent of fasciolosis, which is a widespread livestock disease in Argentina. Determining their geographic distribution and ... -
Genetic control of the tree-ring response of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) to the 2003 drought and heat-wave in France
(Springer, 2008)The genetic control of tree ring growth in Douglas-fir in response to the drought and heat-wave that occurred in 2003 in Europe was studied with microdensity profiles in three clonal experiments located in three different ... -
Genetic diversity and patterns of population structure in Creole goats from the Americas
(Wiley, 2017)Biodiversity studies are more efficient when large numbers of breeds belonging to several countries are involved, as they allow for an in-depth analysis of the within- and between-breed components of genetic diversity. A ... -
Genetic diversity and population structure in Nothofagus pumilio, a foundation species of Patagonian forests: defining priority conservation areas and management
(Springer Nature, 2020-11)Patagonian forests are the southernmost temperate forests in the world, and Nothofagus pumilio is one of their most ecologically important tree species (i.e., a foundation species). It presents great adaptability and a ... -
Genetic progress and economic benefit of community-based breeding programs for sheep out- and upscaling options in Ethiopia
(Elsevier, 2019-08)In this study, expected genetic progress and economic benefits from implementing three community-based breeding programs for sheep (CBBP) out- and upscaling strategies were investigated. Strategy 1 is to replicate average ... -
Genetic Resources: The Base Material for Managing Nature
(Elsevier, 2021)Genetic resources from any biological organism-complete genomes, genes, or even portions of genes that have actual or potential relevance to humans—are a provisioning ecosystem service. They are essential to ensure the ... -
Genetic variation for tolerance to high temperatures in a population of Drosophila melanogaster
(John Wiley & Sons Ltd, 2018-10)The range of thermal tolerance is one of the main factors influencing the geographic distribution of species. Climate change projections predict increases in average and extreme temperatures over the coming decades; hence, ... -
Genetic variation in seedling water-use efficiency of Patagonian Cypress populations from contrasting precipitation regimes assessed through carbon isotope discrimination
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), (España), 2012-07-20)Water-use efficiency (WUE) is a physiological parameter that plays a significant role in the evolutionary dynamics of many forest tree species. It can be estimated indirectly through carbon isotope discrimination (Δ). In ... -
