Padrões de diferenciação florística no extremo sul da Mata Atlântica: influências ambientais e histórica
(Universidade do Vale do Rio dos Sinos, 2011-02-18)
The spatial variation of species abundance can be determined by a series of historical and environmental causes. In order to identify floristic groups and their relationship to a set of soil and climatic variables ...
Convergence in growth responses of tropical trees to climate driven by water stress
(Wiley Blackwell Publishing, Inc, 2019-09)
Widely documented for temperate and cold forests in both hemispheres, variations in tree growth responses to climate along environmental gradients have rarely been investigated in the tropics. Seven tree‐ring chronologies ...
Projected impacts of climate change on functional diversity of frugivorous birds along a tropical elevational gradient
(Nature Publishing Group, 2019-11)
Climate change forces many species to move their ranges to higher latitudes or elevations. Resulting immigration or emigration of species might lead to functional changes, e.g., in the trait distribution and composition ...
Regeneration responses to climate and land-use change of four subtropical tree species of the southern Central Andes
(Elsevier Science, 2018-05)
Land-use and climate change are impacting species and ecosystems around the world. The reproductive phase of plants is especially vulnerable to environmental change. Global environmental changes normally act collectively ...
Comparison of regolith physical and chemical characteristics with geophysical data along a climate and ecological gradient, Chilean Coastal Cordillera (26 to 38 degrees S)
(Copernicus Gesellschaft MBH, 2020)
We combine geophysical observations from ground-penetrating radar (GPR) with regolith physical and chemical properties from pedons excavated in four study areas spanning 1300 km of the climate and ecological gradient in ...
Latitudinal insolation gradients throughout the Holocene II: High frequency variations
(Elsevier, 2020-10)
In a first paper, we presented an in-depth discussion and a computational method (free of the calendar problem) to reckon any kind of latitudinal insolation gradients, LIGs, throughout the Holocene and up to CE 3000. One ...
Efectos de la facilitación en el gradiente altitudinal de Chile central
(2020)
In this research, the spatial and temporal variation of the interactions between species is articulated, based on the stress gradient hypothesis and the temperature predictions of climate change, to account for possible ...
Regionalization of climate over the Argentine Pampas
(John Wiley & Sons Ltd, 2017-04)
The aim of this study was to classify and characterize the climate of the Pampas, a vast region in the centre of Argentina. Due to its territorial extension, a climatic zoning of the region was performed, based on the ...
Invertebrate herbivory rather than competition with tussocks will increasingly delay highland forest regeneration in degraded areas under active restoration
(Elsevier Science, 2022-02-15)
Determining barriers to tree regeneration along elevational gradients is important to predict shifts in regeneration patterns under climate change scenarios. The stress-gradient hypothesis predicts that facilitation ...
