Estimating optimal sampling area for monitoring tropical forest restoration

Spatiotemporal ecological drivers of an aquatic plant community in atemporary t...

Ecological processes that extend over time and space organize plant communities, producing different spatiotemporal patterns of species aggregation (or non-aggregation). To investigate whether the spatiotemporal distribution patterns of the species are generated by interspecific competition and/or environmental filtering, we investigated the organization of an aquatic plant community in a temporary pool in the ...

Assembly rules in a resource gradient: competition and abiotic filtering determ...

The relative importance of different community assembly mechanisms varies depending onthe environment. According to the stress-dominance hypothesis (SDH), assembly mecha-nisms range from strong abiotic filtering to competition as the environment becomes morefavourable. Most evidence for the SDH comes from studies in gradients of conditions (i.e.abiotic environmental factors that influence the functioning of org...

Paleodistribution of Neotropical species of Erythroxylum (Erythroxylaceae) in h...

Variation in environmental conditions during the Quaternary period served as important fi lters for the maintenance of vegetation types and for determining the composition of the current biota. We analyzed oscillations in the distributions of diff erent vegetation types in Brazil during the Quaternary period using species of the genus Erythroxylum (Erythroxylaceae) because of the vast heterogeneity of habitats ...

Made available in DSpace on 2022-04-29T04:22:54Z (GMT). No. of bitstreams: 0 Previous issue date: 2012-01-01; This paper summarizes floristic and phytossociology data of 11, out of 14 plots of 1 ha, allocated along an altitudinal gradient in the Serra do Mar, São Paulo, Brazil. The study was conducted at Serra do Mar State Park and the plots start at the sea level (10 m - plot of Restinga Forest that occurs at ...

Is the spatial pattern of a tree population in a seasonally dry tropical climat...

Spatial pattern of tropical plants is initially generated by limited seed dispersal, but the role of density-dependent and independent mechanisms as modifiers of these patterns across ontogeny is poorly understood. We investigated whether density-dependent mortality (DDM) and environmental heterogeneity can drive spatial pattern across the ontogeny of a tree in a seasonally dry tropical climate. We used Moran’s...

Life history and population dynamics of a tree species in tropical semi-arid cl...

In semi-arid climates, plant population dynamics are strongly influenced by the amount and temporal distribution of rainfall. We monitored a population of the tree species Cordia oncocalyx (Boraginaceae) for 24 months in the dry thorny woodland of semi-arid northeastern Brazil, to investigate which life-history traits allow this tree to be locally dominant. We used horizontal life tables and a Lefkovitch matrix...

A Phytogeographical Metaanalysis of the Semiarid Caatinga Domain in Brazil

Seasonally Dry Tropical Plant Formations (SDTFs) are among the most threatened biomes worldwide. Nevertheless, they have received less scientific attention than rainforests or savannas. One such SDTF, the Caatinga Phytogeographic Domain (CPD), is the largest semiarid tropical ecoregion in South America. Earlier floristic studies of the Caatinga flora discerned two floristic groups in the CPD, in terrains of cry...
