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 ... -
Lexical analysis improves the identification of contextual drivers and farm typologies in the assessment of transitions to agroecology through TAPE – A case study from rural Nicaragua
(Elsevier, 2023-06)CONTEXT: The Tool for Agroecological Performance Evaluation (TAPE) has been developed to assess the degree of transition to agroecology (Step 1) and the agroecological performance (Step 2) of family farms. However, while ... -
Life history traits of Sirex noctilio F. (Hymenoptera: Siricidae) can explain outbreaks independently of environmental factors
(2013-12)La avispa Sirex noctilio es una plaga importante de las plantaciones de pino en todo el mundo. Económicamente daño significativo se limita sin embargo a brote poblaciones. Para entender lo que determina la dinámica de los ... -
Linking ecosystem resistance, resilience, and stability in steppes of North Patagonia
(Elsevier, 2013-01)The main objective of an ecosystem sustainable management is to preserve its capacity to respond and adapt to current disturbances and/or future changes, and maintain the provision of environmental goods and services. Two ... -
Linking reproductive and feeding strategies in the parasitoid Ibalia leucospoides: does feeding always imply profit?
(2013-05)Adquisición y asignación de recursos a diferentes funciones biológicas a lo largo de la vida tienen fuertes implicaciones para el éxito reproductivo de los animales. Los animales pueden experimentar diferentes condiciones ... -
Local adaptation along a sharp rainfall gradient occurs in a native Patagonian grass, Festuca pallescens, regardless of extensive gene flow
(Elsevier, 2020-03)Increasing global aridity combined with changing environmental conditions might cause irreparable alterations in arid and semiarid ecosystems. Knowledge of within-species genetic diversity and adaptive responses, especially ... -
Local dynamics of worker activity of the invasive Vespula germanica and V. vulgaris (Hymenoptera: Vespidae) wasps in Argentina
(2016-02)1. The abundance of insects depends essentially on the reproductive success of individuals. In social insects, however, the abundance of sterile workers outside a nest depends on colony size but is also determined by ... -
Logging by selective extraction of best trees: Does it change patterns of genetic diversity? : The case of Nothofagus pumilio
(2016)Un amplio conocimiento de las consecuencias ecológicas y genéticas de la aplicación de las prácticas de gestión en los ecosistemas naturales es de fundamental importancia para las acciones de conservación. El principal ... -
Long-term coexistence of two invasive vespid wasps in NW Patagonia (Argentina)
(Springer, 2022-07-03)In Patagonia (Argentina) two non-native vespid wasps became established in the last decades. Vespula germanica was first detected in 1980, while V. vulgaris arrived some 30 years later. Both species can have a strong ... -
Long-term grazing negatively affects nitrogen dynamics in Northern Patagonian wet meadows
(Elsevier, 2014-10)Wet meadows are seasonally saturated wetlands that can develop in arid and semi-arid areas. In the semi-arid region of North Patagonia, Argentina wet meadows are islands of high net primary productivity surrounded by low ... -
Long-term monitoring reveals the effect of precipitation and silviculture on Nothofagus regeneration in Northern Patagonia mixed forests
(Springer, 2024-04)Background: Tree regeneration is a key component of resilience because it promotes post-disturbance recovery of forests. Northwestern Patagonia from Argentina is occupied by Nothofagus alpina (Na), N. obliqua (No), and N. ... -
Longitudinal analysis of household types and livelihood trajectories in Oaxaca, Mexico
(Elsevier, 2021-01)In Mexico, a political shift to fit into neoliberal directives since the 80s has brought several consequences to rural households and their trajectories. This study focused on the relation between drivers of change and ... -
Looking at the forest from below: the role of seedling root traits in the adaptation to climate change of two Nothofagus species in Argentina
(2018-05)Global climate change (CC) is an evolutionary challenge for natural tree populations. Scientific experts forecast an increase in temperature and a decrease in precipitation in the Argentine Patagonian Cordillera. Knowledge ... -
“Mal del ciprés”: búsqueda de la causa más probable de daño mediante un análisis deductivo y comparativo = “Cypress Mortality”: search the more probably damage cause by means of deductive and comparative analysis
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2007)The “cypress mortality” (“mal del ciprés”) is a disease of unknown causes, which affects cordillera cypress (Austrocedrus chilensis) in Argentina. In this work a basic guide to diagnosing plant diseases and to compare the ... -
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 ... -
Management of Sirex noctilio populations in exotic pine plantations: critical issues explaining invasion success and damage levels in South America
(Springer Nature, 2018-11)Plantation forestry with non-native trees is steadily increasing in the southern hemisphere and alien pest problems are also accumulating, as a consequence of the growing international movement of people and goods. Here, ... -
