Production potential and structural variability of pine stands in the Czech Republic: Scots pine (Pinus sylvestris L.) vs. introduced pines - case study and problem review

Journal of Forest Science, 2020
Scots pine (Pinus sylvestris L.) is one of the most important tree species in Eurasia. During the past centuries, it has been extensively introduced into artificial monocultures, but is currently experiencing a number of problems related to climate ...

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

Plant 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.

Identification of gene pools used in restoration and conservation by chloroplast microsatellite markers in Iberian pine species

Forest Systems, 2017
Aim of study: To contribute to the characterization of the origin of material used in afforestation, restoration or conservation activities by using Cp-SSR markers. Area of study: We used information from the natural range of Iberian pines, from Spain.

Microsite selection improves post‐fire restoration of singleleaf pinyon pine on Washoe Tribal lands in the Pine Nut Mountains, NV, USA

Restoration Ecology, EarlyView.
Abstract Introduction Singleleaf pinyon pine (Pinus monophylla) holds both ecological and cultural significance for Indigenous Tribes of the Great Basin, such as the Washoe Tribe of Nevada and California. Recent wildfires on Washoe Tribal lands have resulted in the loss of important pinyon pine groves, prompting collaborative efforts to develop post ...

Some Changes in Taxonomy of Pines (Pinus L.) Native to Turkey

Forestist, 2011
Recent taxonomic studies and discussion lead us to overlook the taxonomic positions of the native Pinus L. taxa for Turkey. Based on the latest publications (especially Frankis, 2000; Farjon, 2005, 2010; Zsolt and István, 2010), herbarium and field ...

Impact of plot size and model selection on forest biomass estimation using airborne LiDAR: A case study of pine plantations in southern Spain

Journal of Forest Science, 2017
We explored the usefulness of LiDAR for modelling and mapping the stand biomass of two conifer species in southern Spain. We used three different plot sizes and two statistical approaches (i.e.

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

Journal 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 ...
