Seasonality of mortality in human populations of Chile as related to a climatic gradient
(1984)
Mortality of human populations in Chile was studied from a latitudinal and seasonal perspective, and related to climate and main diseases. Approximately 3 mill. deaths were analyzed. Seasonality considered along a latitudinal ...
Biogeographic anomalies in the species richness of Chilean forests: Incorporating evolution into a climatic – historic scenario
(Ecological Society of Australia, 2013)
Broad-scale richness gradients are closely associated with temperature and water availability. However,
historical and evolutionary processes have also contributed to shape current diversity patterns. In this paper we
focus ...
Relación clima-crecimiento radial de Polylepis australis en un gradiente altitudinal en las Sierras Grandes de Córdoba, ArgentinaClimate-radial growth relationship of polylepis australis along an altitudinal gradient in the Sierras Grandes de Córdoba, Argentina
(Asociación Argentina de Ecología, 2018-06)
Altitudinal gradients represent strategic sites for studying the relationships between climate and growth in woody species. Polylepis australis Bitt. is an endemic tree of Central and Northwest Argentina mountains, growing ...
Mountain invasions on the way: are there climatic constraints for the expansion of alien woody species along an elevation gradient in Argentina?
(Oxford University Press, 2015-10)
Aims Increasing evidence worldwide indicates that high mountain regions are not immune to invasion by alien plants. Here we aimed to address whether three major woody invaders of low-mountain areas are constrained to lower ...
Primary production of lowland natural grasslands and upland sown pastures across a narrow climatic gradient
(2017-04)
Variation in aboveground net primary production (ANPP) is usually studied across wide environmental gradients focusing on spatial averages of zonal natural communities. We studied the spatial and temporal variation of ANPP ...
Soil fertility shapes belowground food webs across a regional climate gradient
(Wiley Blackwell Publishing, Inc, 2017-10)
Changes in soil fertility during pedogenesis affect the quantity and quality of resources entering the belowground subsystem. Climate governs pedogenesis, yet how climate modulates responses of soil food webs to soil ageing ...
The climate of Península Valdés within a regional frame
(Springer, 2017)
Peninsula Valdés shares with the whole of Eastern Patagonia the main features of the regional climate, i.e, scarce rainfall, strong winds and cool-temperate temperatures. Not with standing it has an ill-defined climate ...
Distribution patterns of alien plants in protected natural areas and their adjacent areas of south-central Chile Patrones de distribución de plantas introducidas en áreas silvestres protegidas y sus áreas adyacentes del centro-sur de Chile
(2013)
Natural protected areas (ASP) located in the south-central Chile (Región Metropolitana-Región de la Araucanía) are a conservation relict embedded in agricultural and silvicultural matrices. We compared the taxonomic diversity ...
Possible combined effects of climate change, deforestation, and harvesting on the epiphyte Catopsis compacta: a multidisciplinary approach
(Ecology and Evolution, 2013-09-17)
Climate change, habitat loss, and harvesting are potential drivers of species
extinction. These factors are unlikely to act on isolation, but their combined
effects are poorly understood. We explored these effects in ...
