Estratégias de persistência e regeneração em campo sujo de Cerrado após o fogo
(Universidade Estadual Paulista (Unesp), 2017-05-12)
Em ambientes onde ocorre o fogo, as espécies de plantas podem regenerar via rebrote, semente ou através de ambas as estratégias. Os mecanismos de regeneração são favorecidos ou limitados tanto pelas condições ambientais ...
Glacier and terrestrial ecosystem evolution in the Chilotan archipelago sector of northwestern Patagonia since the Last Glacial Termination
(2022)
We examine the glacier, terrestrial ecosystem, and climate evolution since the Last Glacial Termination (T1) based on glacial sediments/landform assemblages and palynological data from the Chilotan archipelago (41°30′S-43°30′S), ...
Fire has little to no effect on the enhancement of germination, but buried seeds may survive in a Neotropical wetland
(Elsevier B.V., 2021-05-01)
Contrasting responses of seed germination to fire have been reported in different vegetation worldwide. In Brazil, the Pantanal harbors one of the world?s most extensive floodplains, marked by flooding periods alternating ...
Dispersal limitation, soil, and fire affect functional properties of tropical secondary forests on abandoned cattle ranching landscapes
(2021)
Forest age is a major predictor of secondary forest functional properties and through the chronosequence approach continues to be a principal focus in local, landscape, and regional-scale studies of secondary succession. ...
Disturbance induced changes in species and functional diversity in southern Patagonian forest-steppe ecotone
(Elsevier Science, 2015-10)
Ecotone areas are the most dynamic areas of the world where small changes in some condition produce rapid and abrupt responses such as shifts in the distribution of dominant species and associated community's patches. ...
Effects of high temperatures in the germination and seed survival of the invasive species Pinus contorta and two native species of South ChileEfecto de la alta temperatura en la germinación y supervivencia de semillas de la especie invasora Pinus contorta y dos especies nativas del sur de Chile
(Universidad Austral de Chile, Facultad de Ciencias Forestales y Recursos Naturales., 2017)
Effects of Fire on Seedling Diversity and Plant Reproduction (Sexual vs. Vegetative) in Neotropical Savannas Differing in Tree Density
(Wiley, 2014-03)
Little is known about the effects of fire on the structure and species composition of Neotropical savanna seedling communities. Such effects are critical for predicting long-term changes in plant distribution patterns in ...
The role of morpho-physiological traits in frost tolerance of neotropical savanna trees
(2021-10-01)
Key Message: Frost-sensitive and frost-resistant Cerrado tree species differ in their morphological and physiological traits, which are linked with their resprout strategies and can affect their persistence under recurrent ...
