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 ... -
Spatial heterogeneity in species composition constrains plant community responses to herbivory and fertilisation
(Wiley, 2018-09)Environmental change can result in substantial shifts in community composition. The associated immigration and extinction events are likely constrained by the spatial distribution of species. Still, studies on environmental ... -
State and transition model approach in native forests of Southern Patagonia (Argentina): linking ecosystem services, thresholds and resilience
(Taylor & Francis, 2017-04)The sustainable use of ñire forests requires knowledge of its dynamics and management to maintain long-term main forest ecosystem services. The aim of this work was to develop a structural–functional state and transition ... -
Structural–functional approach to identify post-disturbance recovery indicators in forests from northwestern Patagonia: a tool to prevent state transitions
(Elsevier, 2015-05)The disruption of the natural post-disturbance recovery process, either by changes in disturbance regime or by another disturbance, can trigger transitions to alternative degraded states. In a scenario of high disturbance ... -
Talleres de restauración de zona incendiadas en San Marcos Sierras
(EEA Manfredi, INTA, 2022-01-01)El pasado 13 a 18 de enero se quemaron 45has en la localidad de San Marcos Sierras debido a un incendio forestal que comenzó en el km 9 del acceso pavimentado a dicha localidad. Personal del INTA AER Cruz del Eje, CONICET, ... -
Tensiones entre conservación de ecosistemas y desarrollo territorial: hacia un abordaje socioecológico en las Ciencias Agropecuarias
(Editorial Potificia Universidad Javeriana, 2018-06)Las ciencias agropecuarias constituyen un vínculo académico entre sociología y ecología. Actualmente, existe la predominancia de una perspectiva tecnocrática orientada a aumentar la productividad y la eficiencia, con una ... -
The role of nurse functional types in seedling recruitment dynamics of alternative states in rangelands.
(2017-02-16)In arid ecosystems, recruitment dynamics are limited by harsh environmental conditions and greatly depend on the net outcome of the balance between facilitation and competition. This outcome can change as a consequence of ... -
Tracking floristic archetypes of Patagonian steppes
(Wiley, 2024-03)Questions: The classification of plant communities is a well-established practice in ecology. However, the factors that determine the distribution of common species and the extent of their dominance and overlap are still ... -
Transformaciones en territorios de interfase Un aporte a la planificación de Sierras Chicas en Córdoba desde los socio-ecosistemas
(Facultad de Arquitectura y Urbanismo, Universidad Nacional de La Plata, 2020-02)El crecimiento de las ciudades latinoamericanas durante los últimos treinta años, en un contexto de cambio global implicó complejas transformaciones territoriales. El desequilibrio relacional entre sistemas naturales y ... -
Unintended consequences of planting native and non-native trees in treeless ecosystems to mitigate climate change
(Wiley, 2024-03)Naturally treeless ecosystems are being replaced by native and non-native trees worldwide, often through deliberate afforestation using forestry tree species. By introducing species having novel traits, such as relatively ... -
Unveiling the increasingly altered patterns of wetland ecosystem functional diversity in the lower Delta of the Paraná River
(Wiley, 2022-07-08)Since climate, environmental and anthropic controls affect ecosystem functioning simul taneously, wetlands are permanently changing at different spatio–temporal scales. Thus, regionalizations based not only on structural, ... -
Vegetation structure is as important as climate for explaining ecosystem function across Patagonian rangelands
(2014-11)1. Drylands cover about 41% of Earth’s land surface, and 65% of their area supports domestic livestock that depends on the above-ground net primary productivity (ANPP) of natural vegetation. Thus, understanding how biotic ... -
Vegetative and thermal performance of an extensive vegetated roof located in the urban heat island of a semiarid region
(Elsevier, 2022-01)Vegetated roofs reduce temperature and heat flow fluctuations on the building's surface mitigating the urban heat island effects and improving other ecosystem services. The objectives of this work were to quantify thermal ... -
La verdadera riqueza de las zonas secas
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2012-12)Científicos de 16 países descubrieron que la diversidad de especies vegetales tiene un efecto muy importante sobre los procesos que regulan el funcionamiento de las tierras secas. -
Why biodiversity increases after variable retention harvesting: A meta-analysis for southern Patagonian forests
(2016-06-01)Effects of forest harvesting on biodiversity can be varied and complex to understand. We provide a meta-analysis of 553 studies plants, insects and birds to identify the general responses to Variable Retention harvesting ...
