La escarificación mecánica aumenta la germinación de semillas de Neltuma alba (Fabaceae), un árbol amenazado del desierto de Atacama

Revista Peruana de Biología
Neltuma alba es un árbol cuyas semillas probablemente fueron dispersadas por animales ya extintos. Actualmente, los frutos son consumidos por zorros, guanacos, burros y cabras, quienes al comerlos escarificarían las semillas, aumentando su germinación ...

Disentangling seed availability and establishment filters at alpine treelines through a decade‐long field manipulation

Journal of Ecology, Volume 113, Issue 12, Page 3830-3844, December 2025.
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.

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 ...

PUYA HAMATA DEMOGRAPHY AS AN INDICATOR OF RECENT FIRE HISTORY IN THE PÁRAMO OF EL ÁNGEL AND VOLCÁN CHILES, ECUADOR-COLOMBIA

Caldasia, 2014
High-altitude páramo grasslands are important for their biodiversity and the ecosystem services that they provide to Andean people, but they are sensitive to disturbances, such as fire.

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.

Cattle and nurse trees shape subtropical forest–grassland ecotones

Journal of Applied Ecology, Volume 61, Issue 10, Page 2430-2443, October 2024.
Tree cover can potentially expand on the subtropical South American grasslands. Reductions in cattle densities and increases in rainfall levels associated with climate change could facilitate forest expansion in this region. Abstract South American subtropical landscapes are dominated by open grasslands and mosaics of forest–grassland formations ...

Identifying predictors of translocation success in rare plant species

Conservation Biology, Volume 38, Issue 2, April 2024.
Abstract The fundamental goal of a rare plant translocation is to create self‐sustaining populations with the evolutionary resilience to persist in the long term. Yet, most plant translocation syntheses focus on a few factors influencing short‐term benchmarks of success (e.g., survival and reproduction).

Efectos del fuego y del pastoreo sobre la regeneración por semillas de Paspalum quadrifarium en la Pampa Deprimida, Argentina

Ecología Austral, 1994
El uso ganadero de los pajonales de Paspalum quadrifarium en la Pampa Deprimida generalmente implica el manejo combinado del fuego y del pastoreo. Con elfin de evaluar el efecto de estos dos disturbios, y su interacción, sobre la dinámica poblacionel de

Remoción de semillas, herbivoría y reclutamiento de plántulas de Brosimum alicastrum (Moraceae) en sitios con manejo forestal contrastante de la selva maya, Quintana Roo, México

Botan‪ical Sciences, 2009
En este trabajo se evaluó el impacto de la extracción forestal sobre la remoción de semillas, herbivoría y establecimiento de Brosimum alicastrum. Para esto, se utilizaron una serie de exclusiones experimentales colocadas en sitios con manejo y sin ...
