Post-effects of long-term water drougth in Mediterranean pine stands

open access: yesForest@, 2008
Two studies were carried out on the effects of imposed water shortage in two Mediterranean pine stands growing in Southern Italy. The impact of a severe reduction in water availability on the growth of 50-year old Pinus halepensis trees (growing along ...

Size mediated climate–growth relationships in Pinus halepensis and Pinus pinea

open access: yesTrees, 2009
Functional processes in trees undergo changes as the tree size increases, which may affect the response of trees to environmental factors. We tested tree-ring response to climate in four groups of trees, including large and small Pinus halepensis and Pinus pinea trees using cluster, principal component (PC) and dendroclimatological analysis.

Fluctuación estacional y dinámica microbiana en una catena afectada por el abandono del cultivo en la cuenca del Guadalentin (Murcia)

open access: yesPirineos: Revista de Ecología de Montaña, 1995
La distribución espacial de la actividad biológica muestra una clara influencia del uso del suelo. Las zonas con vegetación potencial, Pinus halepensis, tienen altos niveles de carbono microbiano (1.200 μg C g-1), mientras que los suelos situados entre ...

From glacial echoes to timber pathways: Climatic–historical drivers and timber‐trade influence on the phylogeography of Ips sexdentatus in the Basque Country

open access: yesAgricultural and Forest Entomology, EarlyView.
Ips sexdentatus is expanding across southern Europe, attacking multiple Pinus species and showing the ability to colonize trees at early stages of decline. Genetic analysis of 668 individuals revealed 106 haplotypes, with Iberian populations as diversity hotspots, reflecting long‐term refugial persistence alongside more recent demographic expansion ...

Thermotolerance thresholds of the photosystem II increase with elevation in conifer species in the Spanish Pyrenees

open access: yesPlant Biology, EarlyView.
In vitro‐tested photosystem II thermotolerance of seven temperate conifers indicated higher thermal thresholds in species growing in high elevations compared to those in the lowlands. Higher thermotolerance might be explained by the adaptation of species in higher elevations to extreme diurnal temperature fluctuations.

Reciprocal relations shape cultural landscapes: Women's environmental stewardship in Ait Bouguemez (High Atlas, Morocco)

open access: yesPeople and Nature, Volume 8, Issue 8, Page 2847-2865, August 2026.
Abstract Mountain social–ecological systems encompass steep ecological gradients and diverse cultural practices, yet the relative roles of these factors in shaping mountain landscapes remain underexplored. In particular, the knowledge and practices of women in coproducing biocultural landscapes are often invisible in the academic literature. In the Ait

Identifying climatic refugia: Wet and complex habitats act as buffer for birds during severe droughts

open access: yesJournal of Applied Ecology, Volume 63, Issue 8, August 2026.
Wet habitats and complex vegetation, therefore, are critical for providing stable microsites and water resources, underscoring the need to preserve and enhance the resilience of these habitats to support biodiversity during extreme events. Our study provides valuable insights for conservation strategies that should focus on identifying refugia ...
