Treeline advance under warming occurs only when multiple filters align—adequate seed supply, favourable microclimatic windows, moderated herbivory and shrub effects that remain facilitative rather than competitive. Abstract Climate warming is expected to increase upslope shifts of alpine treelines globally.

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 ...

Germinación y viabilidad de semillas de Amburana cearensis (Fabaceae)
Ayarde, Hugo R., 2006. ?Germinación y viabilidad de semillas de Amburana cearensis (Fabaceae)?. Lilloa 43 (1-2). Amburana cearensis (Allemao) A.C. Sm. es una especie de gran importancia forestal que en el Noroeste Argentino ha disminuido fuertemente sus

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 ...

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
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 ...
