Ecological and physiological thermal niches to understand distribution of Chagas disease vectors in Latin America
(John Wiley & Sons Ltd, 2018-03)In order to assess how triatomines (Hemiptera, Reduviidae), Chagas disease vectors, are distributed through Latin America, we analysed the relationship between the ecological niche and the limits of the physiological thermal ... -
Ecological effects and management of invasive alien Vespidae
(Springer, 2011-08)Insect species associated with human goods continue to be accidentally introduced into new locations. A small proportion of these introduced species become invasive, causing a range of impacts in the receiving community. ... -
Ecology and management of invasive Pinaceae around the world : progress and challenges
(2017-06)Many species in the family Pinaceae are invaders. These species are relatively easy to control because of some of their intrinsic characteristics and because they are highly visible and easy to eliminate. Many Pinaceae ... -
Ecology of the woodwasp Sirex noctilio : tackling the challenge of successful pest management
(2012-08)The invasive woodwasp Sirex noctilio has become one of the most significant pests of pine forests throughout the northern and southern hemispheres. In Patagonia (southern Argentina), S. noctilio was first detected in the ... -
Economic costs of invasive non-native species in urban areas: an underexplored financial drain
(Elsevier, 2024-03)Urbanization is an important driver of global change associated with a set of environmental modifications that affect the introduction and distribution of invasive non-native species (species with populations transported ... -
Ecophysiological basis of wood formation in ponderosa pine : linking water flux patterns with wood microdensity variables
(2015-06)Climate and stands management have an effect on the process of wood formation via resource availability. To improve knowledge of wood quantity and physical structure, increment cores of ponderosa pine were taken in high- ... -
Ecosystem services and disservices associated with pastoral systems from Patagonia, Argentina –A review
(EDP Sciences, 2021-11-11)Pastoral systems worldwide secure rural livelihoods in the harshest environments on Earth. Their low productivity per area unit or head makes them the subject of much criticism with regard to their environmental impact, ... -
Ecosystem services to support environmental and socially sustainable decision-making
(Asociación Argentina de Ecología, 2017-04)The theory of ecosystem services (ES) needs to be operationalized to contribute to practices leading to sustainable use of ecosystems, which includes solving trade-offs between private and public benefits and incorporating ... -
Ecosystemic structural–functional approach of the state and transition model
(Wiley, 2011-02)Objective: To contribute to the integration of key ecological concepts such as dynamic equilibrium, critical threshold, resistance and resilience to the ‘State and Transition Model’ (STM), in order to apply them in a more ... -
Ectomycorrhizal fungal communities in Nothofagus nervosa [Rauli] : a comparison between domesticated and naturally established specimens in a native forest of Patagonia, Argentina
(2015-12)Due to its overexploitation during the past century, Nothofagus nervosa is currently included in conservation and domestication programs, in which ectomycorrhizas play an important role. We aimed to describe the abundance ... -
Ectomycorrhizas naturally established in Nothofagus nervosa seedlings under different cultivation practices in a forest nursery
