Measuring maternal line selection driven by differential survival in ex situ collections for plant conservation

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Ex situ plant collections may be increasingly needed to protect representative samples of threatened or rare species and provide plant material for conservation translocation. A primary problem in these ex situ collections is loss of intraspecific variation due to plant death. Different management actions would be required depending on whether

Effects of Warming on Growth and Leaf Colonization by Litter Mat‐Forming Fungi in a Wet Tropical Forest in Puerto Rico

Biotropica, Volume 58, Issue 3, May 2026.
We took advantage of a long‐running field warming experiment, the Tropical Responses to Altered Climate Experiment (TRACE) located in the Luquillo Experimental Forest in Puerto Rico to evaluate the effects of +4°C warming on relative growth rates (RGR) and time to leaf colonization of a recently senesced leaf for drought‐tolerant species Marasmius ...

Phytochemical diversity of naturally regenerated plants in a biodiversity enrichment experiment

Journal of Ecology, Volume 114, Issue 3, March 2026.
Tree islands established within an industrial oil palm plantation promoted the recovery of phytochemical diversity through natural regeneration. Ten years after planting, untargeted metabolomics of 76 regenerating woody species detected 27,122 phytochemical features, including many novel compounds. Larger islands supported higher woody species richness

Tree species abundance changes at the edges of their climatic distribution: An interplay between climate change, plant traits and forest management

Journal of Ecology, Volume 112, Issue 12, Page 2785-2797, December 2024.
Our research emphasizes the crucial impact of historical forest management in shaping the current distribution of tree species. After controlling for the effect of forest management, climate change directly influenced tree demographics, favouring species based on their traits.

An ecological perspective for analysing rural depopulation and abandonment

People and Nature, Volume 6, Issue 2, Page 490-506, April 2024.
Abstract Population loss in rural areas is rapidly increasing in high‐income countries, raising concerns and debate, given its socio‐economic consequences. Despite the evident environmental dimension of the phenomenon, ecological knowledge has been neglected in the analysis of actions aiming to reverse rural depopulation.
