Blowin' in the Wind: Ferns and Lycophytes Connect Biogeographic Refuges in the Atlantic Forest

open access: yesJournal of Biogeography, Volume 52, Issue 11, November 2025.
ABSTRACT Aim Test the floristic structure of fern and lycophyte in the Northeastern Atlantic Forest based on the two sub‐regions of endemism, (1) montane inland wet forests and (2) Coastal Forests. Location Northeastern Brazil's Atlantic Forest, particularly the Coastal and Montane inland wet forests. Taxon Ferns and lycophytes.

Marked tree demographic variation along subtle elevation differences partially explains species' habitat associations in an Amazonian forest

open access: yesJournal of Ecology, Volume 113, Issue 10, Page 2860-2874, October 2025.
These findings show that even small differences in elevation can lead to biologically meaningful variation in resource access that translates into significant differences in tree growth and survival. However, resource access could not fully explain the patterns of topographically driven demographic variation we observed. While certain species may still

Surviving in a Warming and Fragmented World: Long‐Term Population Dynamics of the Lizard Gonatodes humeralis

open access: yesAustral Ecology, Volume 50, Issue 10, October 2025.
ABSTRACT Climate change presents significant challenges to species survival; however, the long‐term effects on tropical lizard populations remain poorly understood. Previous studies have predicted contrasting outcomes, with some forecasting a high risk of extinction due to rising temperatures, while others suggest greater resilience in tropical ...

Dinâmica de raízes de espécies arbóreas: visão da literatura.

open access: yesCiência Florestal, 2009
A dinâmica do sistema radicular de uma planta é de extrema importância para definições de técnicas de manejo nas áreas agrícola e florestal. A raiz, além de ter a função básica de sustentar a planta, é o meio de esta absorver água e nutrientes ...

Migration Patterns of Epiphyllous Bryophyte Metapopulations in Amazonian Fragmented Landscape Inferred From Census and Genomic Data

open access: yesBiotropica, Volume 57, Issue 5, September 2025.
We examined the long‐term genetic consequences of habitat fragmentation on two epiphyllous bryophyte species in experimentally fragmented Amazonian forests. Using genotyping and demographic data, we found species‐specific responses and metapopulation dynamics in relation to their mating system.

Towards a global understanding of tree mortality [PDF]

open access: yesnew phytologist.
Summary Rates of tree mortality are increasing globally, with implications for forests and climate. Yet, how and why these trends vary globally remain unknown. Developing a comprehensive assessment of global tree mortality will require systematically integrating data from ground‐based long‐term forest monitoring with large‐scale remote sensing.

BioTIME 2.0: Expanding and Improving a Database of Biodiversity Time Series

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 5, May 2025.
ABSTRACT Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic ...
