Physico-chemical properties of plant cuticles and their functional and ecological significance
(2017-11)Most aerial plant surfaces are covered with a lipid-rich cuticle, which is a barrier for the bidirectional transport of substances between the plant and the surrounding environment. This review article provides an overview ... -
Plasticidad ecofisiológica de plántulas de Nothofagus pumilio frente a combinaciones de niveles de luz y humedad en el suelo
(Asociación Argentina de Ecología, 2011)Las propuestas silvícolas para el manejo de los bosques de Nothofagus pumilio se basan sobre la apertura del canopeo para estimular el crecimiento de la regeneración natural; de esta manera se incrementa la disponibilidad ... -
Positive biodiversity-productivity relationship predominant in global forests
(American Association for the Advancement of Science, 2016-10-14)The biodiversity-productivity relationship (BPR) is foundational to our understanding of the global extinction crisis and its impacts on ecosystem functioning. Understanding BPR is critical for the accurate valuation and ... -
Potential biodiversity map of bird species (Passeriformes): Analyses of ecological niche, environmental characterization and identification of priority conservation areas in southern Patagonia
(Elsevier, 2023-06)Different methodologies try to identify priority conservation areas (PCA) to improve habitat conservation and decrease human pressures over bird species at coarse-scale. Map of potential biodiversity (PB) can identify PCA ... -
Potential biodiversity map of darkling beetles (Tenebrionidae): environmental characterization, land-uses and analyses of protection areas in Southern Patagonia
(Springer, 2019-07-23)Different methodologies had been developed for species management and conservation based on modelling of potential biodiversity at regional scales. However, most of these models were fitted for umbrella species (e.g. big ... -
Potential biodiversity map of lizard species in Southern Patagonia: environmental characterization, desertification influence and analyses of protection areas
(2018)The distribution of biodiversity at the landscape level is shaped by biotic, abiotic and anthropogenic factors. Biodiversity maps provide the basis for defining management and conservation strategies that can minimize human ... -
Potential biodiversity map of understory plants for Nothofagus forests in Southern Patagonia: Analyses of landscape, ecological niche and conservation values
(Elsevier, 2019-09)The role of understory plants in native forests is critical for ecosystem function, wildlife protection and ecosystem productivity. The interest to estimate biodiversity increased during the last decades at landscape level. ... -
Precipitation is the key determinant of topsoil δ15N values in southern Patagonia’s semiarid rangelands
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2022-02-11)Nitrogen (N) cycling in rangeland soils could potentially be controlled by water supply, stocking rates, or a range of other variables, such as ecosystem N stocks. To gauge the relative importance and elucidate possible ... -
