The geographic selection mosaic for squirrels, crossbills and Aleppo pine [PDF]

Journal of Evolutionary Biology, 2004
Abstract The interactions between many species are structured in a geographic mosaic of populations among which selection is divergent. Here we tested the hypothesis that such a geographic selection mosaic arises for common crossbills ( Loxia curvirostra ) feeding on seeds ...

Influence of partial serotiny of Aleppo pine, Italian, and Arizona cypress on seed germination [PDF]

Glasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2006
The usability of seeds for the production of seedlings, as well as the utilisation potential of seeds for natural regeneration was assessed by the comparative analysis of seed germination from the cones of different ages of three species with partial ...

Long-Term Assessment of Spatio-Temporal Landuse/Landcover Changes (LUCCs) of Ošljak Island (Croatia) Using Multi-Temporal Data—Invasion of Aleppo Pine

Land, 2022
The karst landscapes of the Mediterranean are regarded as some of the most vulnerable, fragile, and complex systems in the world. They hold a particularly interesting group of small islands with a distinctive, recognizable landscape.

Aflatoxin in Tunisian Aleppo Pine Nuts

Journal of AOAC INTERNATIONAL, 1977
Abstract Twenty-six of 50 Aleppo pine nut samples collected throughout Tunisia showed relatively high levels of contamination by aflatoxin. Some samples contained as much as 2000 ppb aflatoxin B1, and very few contained less than 100 ppb. Total aflatoxins as high as 7550 ppb were found.

Phenols and Flavonoids in Aleppo Pine Needles as Bioindicators of Air Pollution [PDF]

Journal of Environmental Quality, 2003
ABSTRACTThe aim of the present study is to assess whether certain ecophysiological responses (contents of total phenols, total proanthocyanidins, and total and simple flavonols), in the needles of Aleppo pines (Pinus halepensis Mill.) may be valid bioindicators for the assessment of the air quality.

Postfire regeneration of Aleppo pine – the temporal pattern of seedling recruitment [PDF]

Plant Ecology, 2004
The temporal dynamics of Pinus halepensis seedling emergence, density and survival were studied in detail during the first postfire year, in five Aleppo pine forests of Attica (Stamata, Villia, Avlona, Kapandriti and Ag. Stefanos; burned in June 1990, July 1990, September 1991, September 1992 and July 1993, respectively).

Tree Growth, Contraction and Recovery: Disentangling Soil and Atmospheric Drought Effects. [PDF]

Plant Cell Environ
ABSTRACT We investigate how soil and atmospheric droughts jointly impact tree growth and recovery dynamics in a semi‐arid pine forest, leveraging high‐resolution stem diameter variation data and an irrigation experiment. The irrigated plot, where soil drought was mitigated, served as a benchmark to isolate the effects of atmospheric drought and ...

Abnormal Shoot and Leaf Formation in Some Native Pine Species

Forestist, 2011
In many tree species, when abnormal shoot formation after fire, insect attack and grazing is being observed, this formation is not common in pine species and not well-known.
