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

open access: yesJournal 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.

Potencial Hídrico Foliar de Tres Especies Arbustivas de un Ecosistema Semiárido en el Norte de México

open access: yesTerra Latinoamericana
El cambio climático es un fenómeno global, sus repercusiones alteran el funcionamiento y la integridad de los ecosistemas. El impacto más marcado del cambio climático es el estrés hídrico, de ahí la importancia de los estudios de selección de plantas y ...

Foliar herbivory pushes plant individuals towards the periphery of a plant–floral visitor interaction network

open access: yesJournal of Ecology, Volume 113, Issue 9, Page 2414-2428, September 2025.
The authors demonstrate how the effects of herbivory on a key plant trait can cascade to shape the interactions between individual plants and their flower visitors and how the indirect effects between herbivores and pollinators can modulate the structure of interaction networks in terrestrial ecosystems.

Revisiting the Narrative of Deforestation in Central and Southern Mainland Early Modern Portugal as a ‘Ruined Landscape’: The Case of Shipbuilding in Lisbon

open access: yesHistory, Volume 110, Issue 389, Page 24-48, January 2025.
Abstract Scholars have largely blamed shipbuilding for maritime expansion for being the main driver of deforestation in early modern Portugal. This article sets out to revisit the origins and reproduction of this narrative by analysing three interconnected elements in a case study of Lisbon's shipyards.

¿Protegen las espinas arbustivas a los nidos de aves contra la depredación? Un análisis experimental en la estepa patagónica

open access: yesEcología Austral, 2018
La depredación de nidos es una de las presiones de selección más importantes para las aves, por lo que la elección del sitio de nidifcación es clave para la supervivencia de los polluelos.

Effects of manakin gut passage on germination of a neotropical melastome shrub (Melastomataceae)

open access: yesBiotropica, Volume 57, Issue 1, January 2025.
In a paired germination experiment, we found that manakin gut passage accelerated germination of a common and widespread Melastome shrub, Miconia rubescens, which may function as an important pioneer in regenerating rainforest. Manakin species varied in their gut passage effects and within species, body mass correlated with greater and earlier ...

Reintroduction affects demographic rates but not their interannual correlations in an endangered shrub

open access: yesJournal of Applied Ecology, Volume 61, Issue 12, Page 3040-3052, December 2024.
Our study shows that stressful conditions may trigger individual‐level trade‐offs in resource allocation and population‐level compensation among demographic rates. Demographic shifts arising from reintroductions in different environmental conditions may be considered by managers as a potential mechanism of resilience against environmental change ...
