Long-term implications of traditional forest regulation methods applied to Maritime pine (Pinus pinaster Ait.) forests in central Spain: a century of management plans

open access: yesiForest - Biogeosciences and Forestry, 2010
Pinus pinaster stands in the northern Iberian range (Spain) have been under forest management plans for more than a century. The main goals have been sustainable yield and conservation and enhancement of forest conditions.

Chromosome‐level genome assembly and annotation of Ulmus minor reveal dynamic intrageneric clusters of resistance genes

open access: yesThe Plant Genome, Volume 18, Issue 3, September 2025.
Abstract The field elm (Ulmus minor) is an emblematic species of the European landscape, which has been severely affected by Dutch elm disease (DED) since the 20th century. To support restoration and conservation of this species and congeners, we present a de novo assembly and annotation of a wild genotype tested positive for DED resistance, along with

Gene Flow and Vertical Stratification of Pollination in the Bat‐Pollinated Liana Marcgravia longifolia

open access: yesEcology and Evolution, Volume 15, Issue 8, August 2025.
This study investigates pollen dispersal, vertical stratification of gene flow, and spatial genetic structure in the bat‐pollinated liana Marcgravia longifolia in a western Amazonian forest. Flowers are produced from the forest floor to the canopy, allowing analysis of pollination across strata.

Use of community characteristics to predict hunting and game harvests in western Amazonian forests

open access: yesConservation Biology, Volume 39, Issue 4, August 2025.
Abstract Wild game harvesting in Amazonia provides rural residents with protein and cash income but can threaten wildlife populations and forest ecosystem functions. As yet, the socioeconomic and environmental drivers that shape hunter livelihoods remain poorly understood.
