Dynamics and trajectories of secondary succession in Central Amazonia [PDF]

Boletim do Museu Paraense Emílio Goeldi. Ciências Naturais, 2012
Land use history is a primary driver of secondary succession in the Central Amazon, resulting in the establishment of distinct trajectories differing in structure, composition, biomass and dynamics. Intensive use with prescribed fire to maintain pastures

Habitat differences in seed‐dispersing vertebrates indicate dispersal limitation in tropical bracken‐dominated deforested areas

Biotropica, Volume 56, Issue 3, May 2024.
Forest regeneration in tropical bracken‐dominated deforested areas is mainly hindered by dispersal limitation. We found differences in species composition of seed‐dispersing birds and bats between the forest and bracken‐dominated areas, which could be one of the main causes of dispersal limitation in forest regeneration in tropical bracken‐dominated ...

Plantas daninhas de uma pastagem cultivada de baixa produtividade no Nordeste Paraense Weeds of pasture low yielded areas of northeastern in the Pará State

Planta Daninha, 1999
Atualmente existem 23 milhões de hectares de pastagens cultivadas em área originalmente sob floresta na Amazônia. Desse total, em torno de cinco milhões de hectares encontram-se com baixa produtividade ou em vias de degradação, infestados de plantas ...

Patterns in the genetic structure of 49 lowland rain forest tree species co‐distributed on opposite sides of the northern Andes

Biotropica, Volume 56, Issue 2, March 2024.
The northern Andes are a major biogeographic dispersal barrier to lowland rain forest trees. We examine genetic diversity and divergence of paired populations of 49 rain forest tree species co‐distributed on opposite sides of the Andes and show that dispersal across or around this biogeographic barrier has left enduring genetic signatures. Abstract The

Incomplete recovery of tree community composition and rare species after 120 years of tropical forest succession in Panama

Biotropica, Volume 56, Issue 1, Page 36-49, January 2024.
The late stages of tropical forest succession are understudied. Here we analyze tree community recovery over one of the oldest chronosequences in the Neotropics and find recovery of species diversity and forest structure, within 40 and 90 years respectively, but species community compositional recovery is slow, with one plot converging on old‐growth ...

Eficiência no uso dos nutrientes por espécies pioneiras crescidas em pastagens degradadas na Amazônia central Nutrient use efficiency for pioneer species grown on abandoned pastures in central Amazonia

Acta Amazonica, 2006
Nas últimas décadas, considerável parcela da floresta amazônica tem sido transformada em pastagens que, em função da baixa fertilidade natural dos solos e do manejo deficiente, decrescem rapidamente em produtividade e são abandonadas, dando lugar a uma ...

The Meaning of Plants’ Names: A New Discovering Approach to Its Medicinal and/or Toxic Properties

Evidence-Based Complementary and Alternative Medicine, Volume 2024, Issue 1, 2024.
Some of the vernacular or scientific names are related to possible medicinal and/or toxic properties that can reveal the presence of potential bioactive agents, contributing to the discovery of new drugs and/or knowledge of the risks associated with their use.
