Habitat Conditions and Neighborhood Interactions Drive the Phylogenetic Structure of Seedling Assemblages in a Tropical Forest Mosaic

Biotropica, Volume 57, Issue 6, November 2025.
In poor, well‐drained sandy soils, we observed the coexistence of more closely related species, suggesting that shared evolutionary history influences which seedlings survive under these restrictive conditions. Contrary to expectations, flooded areas harbored more distantly related species, likely because pathogens and other natural enemies limit the ...

Influência do porta-enxerto no comportamento fisiológico de mudas de cajueiro (Anacardium occidentale L.) submetidas a estresses

Revista Brasileira de Fruticultura, 2003
O uso de mudas enxertadas uniformiza o crescimento de plantas e antecipa o início da produção. Os porta-enxertos regulam aspectos, como taxa fotossintética e relações hídricas das mudas, e distúrbios sobre os mesmos afetam o vigor geral das mudas.

How do drought and elevated temperatures influence CO2 fertilization effects on tree seedling performance? A global meta‐analysis

Journal of Ecology, Volume 113, Issue 10, Page 2875-2888, October 2025.
These results suggest that the fertilization effect of CO2 at the seedling stage may be limited when additional environmental stressors, such as drought, are present. The combined effect of drought, temperature and CO2 mainly resulted in additive effects, where each stressor independently influences plant performance rather than interacting to amplify ...

Above‐ground competition by Nephrolepis brownii inhibits tree seedling recruitment in a tropical restoration experiment

Journal of Applied Ecology, Volume 62, Issue 8, Page 1968-1979, August 2025.
As Nephrolepis brownii primarily interferes through above‐ground competition, management of above‐ground tissues may mitigate its impact. However, additional research on the efficacy of this management strategy and potential allelopathic traits is needed.

The Rapid Recovery of a Caatinga Dry Forest is Mediated by Disturbance‐Adapted Species

Biotropica, Volume 57, Issue 4, July 2025.
Overall, regenerating and old‐growth forest stands exhibited similar plant diversity across all ontogenetic stages, with a negligible role played by forest stand age, precipitation, and chronic human disturbance. Species exclusively recorded as adults or seeds were mostly dispersed by animals, indicating that several species fail in either dispersing ...

Decadal survival of tropical pioneer seeds in the soil seed bank is accompanied by fungal infection and dormancy release

Functional Ecology, Volume 39, Issue 6, Page 1483-1494, June 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Pioneer trees require high‐light environments for successful seedling establishment. Consequently, seeds of these species often persist in the soil seed bank (SSB) for periods ranging from several weeks to decades.
