... This study investigated the antioxidant, anthelmintic and antibacterial activities of essential oil obtained from red juniper (Juniperus phoenicea) leaves. Red juniper essential oil yield was 0.80%. The GC-MS analysis of this essential oil showed that α -pinene (74.14%) was the predominant component. The anthelmintic activity assay of red juniper essential oil was performed on Haemonchus contortus ...
... Several dieback episodes triggered by droughts are revealing the high vulnerability of Mediterranean forests, manifested as declines in growth, increased defoliation, and rising mortality rates. Understanding forest responses to such climate extreme events is of high priority for predicting their future vegetation dynamics. We examined how remotely sensed measures of vegetation activity (NDVI, Nor ...

... Juniperus turbinata Guss. is a native species of Morocco; however, an exhaustive taxonomic description based on phenotypical characterization of north-eastern Moroccan population species is lacking, which might lead to taxonomic confusion. In order to expound the phenotypic description of J. turbinata of the north-eastern Moroccan population and to examine the taxonomic differences within it; a co ...
... Shrub encroachment (SE) is a phenomenon in which grasses and herbaceous vegetation are replaced by woody shrubs. Many previous studies have highlighted the effects of SE on soil respiration rates and nutrient storage, but little is known about impacts on soil microbiota. While previous work considered shrubs to be non-species specific or as a single intervening species, we selected an Ampelodemsos ...

Many grasses and forbs are valuable livestock foods, but the forage value of the Mediterranean shrubs varies considerably. We experimentally determined the effect of supplementing goats with activated charcoal (Ach) and barley and barley alone, on the intake of five dom ...
... Fourteen natural populations of Juniperus phoenicea L. from the quite entire species range have been compared using isoenzyme polymorphism. Among 17 loci, 5 (Got1, 6Pgd3, Pgi2, Pgm2 and Shdh2) appeared to be differentiated sufficiently to provide useful information for discrimination between the subspecies phoenicea and turbinata (Guss.) Nyman. Two distinct groups of populations were detected usin ...
... Specimens of Salvadora persica Wallich (Salvadoraceae), Pistacia atlantica Desfontaines (Anacardiaceae), and Juniperus phoenicea L. (Cupressaceae) were collected at The Green Mountain in northeastern Libya. The tick-repellent effects of the essential oils from the plants were evaluated using host-seeking nymphs of Ixodes ricinus L. (Acari: Ixodidae) in the laboratory. Significant tick repellent ef ...
... We report here the successful micropropagation of adult Juniperus phoenicea L. with respective ploidy stability studies. Microcuttings with axillary buds were grown on five media supplemented with different growth regulator combinations. Best elongation rates were achieved on Driver and Kuniyuki (DKW) medium supplemented with kinetin alone or with naphthaleneacetic acid (NAA), while Rugini olive ( ...

Abstract:
... The aims of the present study were to determine biochemical properties of honey samples and to discriminate pure and adulterated honey produced by the standard bee feeding method (control honey), the shaking method (pure blossom honey), and overfeeding (100 kg/colony syrup) with sucrose syrup (adulterated honey). The biochemical properties evaluated were moisture, ash, acidity, hydroxymethylfurfur ...
... The chemical study of the essential oil extracted from leaves of Juniperus phoenicea growing in Morocco has been carried out. The main components of J. phoenicea oil were the monoterpene hydrocarbons alpha-pinene (45.5%) and delta-3-carene (13.0%). Our results show a number of differences in composition with respect to a previous study of the leaf oils of J. phoenicea (Greece and Spain). ...

Abstract:
... BACKGROUND AND AIMS: The assessment of the genetic variability and the identification of isolated populations within a given species represent important information to plan conservation strategies on a genetic basis. In this work, the genetic variability in five natural populations of Juniperus phoenicea, three from Sardinia, one from Cyprus and the last one in the Maritime Alps was analysed by me ...
... Maquis and garrigues are extensive shrubland vegetation types in the Mediterranean region that provide important habitat for wild and domestic herbivores. Although the majority of these shrubs are nutritious, virtually all contain secondary compounds that reduce their forage value. Understanding how animals cope with ingesting secondary compounds is vital for increasing consumption of shrubs and f ...
... Question: Which factors affect the spatial variation of maquis and phryganic vegetation and how can the role of human activities be estimated through degradation models.Location: Island of Sifnos, Cyclades, Greece.Methods: Data on woody vegetation, environmental conditions and intensity of human activity were collected by field survey. The vegetation data were analysed using TWINSPAN. Models based ...
... By means of a supercritical fluid extractor, extract of Juniperus phoenicea L. was obtained in a single extraction stage. The yield was 0.2% by mass. The operative conditions were: extractor, pressure, P = 90 bar and temperature, T = 50 degrees C; first separator, P = 90 bar and T = -10 degrees C; second separator, P = 15 bar and T = 10 degrees C. The hydrodistilled oil gave a yield of 0.3% by mas ...
... The effects of summer and winter stress on the chlorophyll and carotenoid contents and photosystem 2 efficiency were examined in six Mediterranean scrub species. These six species belong to two different plant functional types: drought semi-deciduous (Halimium halimifolium L., Rosmarinus officinalis L., Erica scoparia L.) and evergreen sclerophylls (Juniperus phoenicea L., Pistacia lentiscus L., M ...

Abstract:
... Photoinhibition was examined in four co-occurring Mediterranean evergreen tree species during two consecutive winters. In response to low temperatures and saturating light, Juniperus phoenicea L., Pinus halepensis Mill., Quercus coccifera L. and Q. ilex ssp. ballota (Desf.) Samp. exhibited marked chronic photoinhibition, indicated by low predawn maximal photochemical efficiency of photosystem II ( ...
... The composition of the essential oil from ripe and unripe berries and leaves of Juniperus oxycedrus L. ssp. oxycedrus, Juniperus phoenicea ssp. turbinata and Juniperus communis ssp. communis was analyzed by GC-MS, and microbiological assays were carried out. Samples were collected in different localities (Sardinia, Italy) and hydro distilled. The yields ranged between 2.54% ± 0.21 (v\w dried weigh ...
... The aim of the present study was biometrical comparison of three Iberian populations of Juniperus phoenicea, represented by the subsp. turbinata and subsp. phoenicea. Eight features of the cones and seeds, two of the shoots and leaves were studied.The biometrical analysis of three distant populations of J. phoenicea shows great taxonomic distances among them. Two of them, representatives of J. pho ...
... Photosynthetic performance was monitored during two consecutive summers in four co-occurring evergreen Mediterranean tree species growing on a south-facing rocky slope. In response to midday water stress, the drought-avoiding species Pinus halepensis Mill. exhibited marked stomatal closure (g(s)) but no changes in stem water potential (psi(s)), whereas the drought-tolerant species Quercus coccifer ...
Juniperus phoenicea; Mendelian inheritance; allozymes; heterozygosity; loci; men; trees
Abstract:
... Eight enzyme systems coding for 14 loci were assayed in Juniperus phoenicea. Mendelian inheritance was confirmed for allozymes at 10 loci (Fle 2, Gdh, Got 1, Idh, Mdh 1, Mdh 2, Men 1, Pgi, Pgm I, Pgm 2) by testing the fit of band-pattern segregation in macrogametophytes from heterozygous trees to the expected I: I ratio. Linkage relationships were examined for 21 pairs of allozyme loci and these p ...

Abstract:
... The leaf essential oils of Juniperus phoenicea L. (Greece and Spain), J. phoenicea subsp. eu-mediterranea Lebr. & Thiv. and J. phoenicea var. turbinata (Guss.) have been analyzed by GC/MS. All of the oils were dominated by alpha-pinene. Juniperus phoenicea also contained moderate amounts of myrcene, limonene, beta-phellandrene, alpha-terpinyl acetate and 1-epi-cubenol. The oils of J. phoenicea var ...
... (+)-Cedrol (1) was biotransformed by cultures of Steptomyces griseus ATCC 10137 and Bacillus cereus UI 1477 (NRRL B-14591). Metabolites isolated by solvent extraction and chromatography over Si gel and reversed-phase RP-C18 columns and by preparative tlc, were examined by ms and 1H- and 13C-nmr spectroscopy. B. cereus afforded 2S-hydroxycedrol (2) as the only metabolite. The metabolite 2 is appare ...
