Tree demographic strategies largely overlap across succession in Neotropical wet and dry forest communities

open access: yesEcology, Volume 105, Issue 7, July 2024.
Abstract Secondary tropical forests play an increasingly important role in carbon budgets and biodiversity conservation. Understanding successional trajectories is therefore imperative for guiding forest restoration and climate change mitigation efforts.

Feedback loops drive ecological succession: towards a unified conceptual framework

open access: yesBiological Reviews, Volume 99, Issue 3, Page 928-949, June 2024.
ABSTRACT The core principle shared by most theories and models of succession is that, following a major disturbance, plant–environment feedback dynamics drive a directional change in the plant community. The most commonly studied feedback loops are those in which the regrowth of the plant community causes changes to the abiotic (e.g. soil nutrients) or

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

open access: yesBiotropica, 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 ...

Efeito da exploração florestal de impacto reduzido sobre a regeneração natural em uma floresta densa de terra firme no município de Paragominas na Amazônia brasileira. [PDF]

open access: yes, 2015
O estudo foi motivado pela escassez de informações sobre a sustentabilidade ecológica da exploração de florestas naturais, em áreas diretamente afetadas pela exploração. O objetivo foi verificar se há diferença florística entre a floresta não-explorada e

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

open access: yesBiotropica, 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
