The latter grew among some boulders, was of fine habit, and possessed a large orange hip. Overall, the species is not considered threatened with healthy population in Spain;  however, the African population is threatened by severe overgrazingmainly by goatsand is listed as Endangered. x2 analyses were used to test for natural seedling frequency in each of three main microhabitats: (1) under female and (2) male tree canopies and (3) in open interspaces. Because of light attenuation by waxes, we expected that glaucous phenotypes would lower the need for photoprotective pigments. We used a higher number of fruits for analyses of nutritional contents to increase the dry mass of pulp necessary for the different analytical procedures.
The oil yields from fresh leaves showed on differences among geographical sources. Juvenile leaves on seedlings and reappearing on mature plants, in whorls of 4 on lower stem, on branchlets decussate, acicular, mm long with a green adaxial midrib, acute-pungent Farjon In Europe, the species is generally stable, but is vulnerable to habitat loss as woodlands change to forest after abandonment of traditional land use systems.
Specimens tend to have male and female Alnus glutinosa has a fruit very reminiscent of a conifer cone, but much smaller 2 cm. Tracheidograms of four climatic years from two drought-sensitive sites in Spain were compared to evaluate whether it is possible to link intra-annual cell size patterns to seasonal climatic conditions. We experimentally fertirrigated a set of male and female Juniperus thurifera trees monthly for 2 yr.
It is a long-lived species with individual trees lasting for several hundred years . Flowering occurs during February, and female cone growth and ripening takes 20 months. The analysis of the essential oil from the wood of Juniperus thurifera has provided the isolation of seven new natural products, including the first described examples of 2- epi -cedranes and 2- epi -duprezianane. There are still considerable uncertainties about soil functioning in semi‐arid Mediterranean ecosystems. is a dioecious, long‐lived tree with a relictual distribution from the Tertiary throughout the calcareous high mountains of the western Mediterranean Basin.
You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use. NOTE Changes in land use and physiological transitions of a Juniperus thurifera forest: from decline to recovery Daniel Montesinos and Javier Fabado Abstract: Forest decline is frequently associated with infection; however, infections habitually affect trees that have been previously debilitated by environmental stress. Sabina – scale-leaf junipers; adult leaves are mostly scale-like, similar to those of Cupressus species, in opposite pairs or whorls of three, and the juvenile needle-like leaves are not jointed at the base (including in the few that have only needle-like leaves; see below right).

Twenty-four components were identified in the essential oils from the branches of Juniperus thurifera, forty seven from Juniperus oxycedrus and twenty-six from Juniperus phoenicea. Nature Picture Library offers the best nature photographs and footage from the world's finest photographers, to license for commercial and creative use. Juniperus thurifera is a morphologically variable species, per-haps as a result of long-term isolation of disjunct populations. The plastic xylogenesis patterns of junipers in drought-stressed areas may also provide them with a competitive advantage against co-occurring pines. Se ofrecen datos acerca de la dinámica de taxones forestales de interés en la Comunidad de Madrid. PDF | Background: Over the past decade, most antibiotic research programs have focused on finding new compounds with antimicrobial activity.
Water potential, photosynthesis rate and stomatal conductance were measured monthly for 2 yr, while shoot nitrogen (N) concentration, carbon isotopic composition (δ 13 C), branch growth, trunk radial growth and reproductive investment per branch were measured yearly.

were globally very similar and most probably belong to the same species .
Enhancement of Juniperus thurifera recruitment and colonisation by oak and pine species has been related at the local level to changes in livestock pressure. These metrics are regularly updated to reflect usage leading up to the last few days. Abstract Enhancement of Juniperus thurifera recruit-ment and colonisation by oak and pine species has been related at the local level to changes in livestock pressure. Juniperus thurifera is reported as a masting species, i.e., flower and cone production varies between years, with one mast seeding year each 6-years period (Montesinos et al., 2012a), and 2006–2007 was a non-masting period for the species in the study area (Tellería et al., 2011). Juniperus is the most diverse genus within the Cupressaceae and the second within conifers. evergreen tree Juniperus thurifera (L.) to evaluate the impact of epicuticular wax on optical and ecophysiological properties and on the abundance of photoprotective pigments throughout an annual cycle. Juniperus thurifera is an important component of woodland communities of dry sites within the West Mediterranean region and is characterised by a strongly disjunctive geographic range. The species forms low-density forests on poor, shallow, rocky soils that can establish at high altitudes and cover broad climate ranges (Gauquelin et al.1999).
These woodlands are con-sidered to be remnants of the dominant vegetation during drier and cooler past climatic periods (Riera 2006). Stereochemistry in Unusual Cedrane and Duprezianane Series., ChemInform" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips. Methods: The spatial pattern of adult Juniperus thurifera trees was studied by means of Ripley's K-analysis. populations are distributed locally on several areas including coastal cliffs which are difficult to access in the central eastern Korea. This study aims to investigate the chemical composition and antibacterial activity of the essential oil (EO) extracted from ripe berries of Algerian Juniperus thurifera var. It large shrub or tree reaching 6–20 m tall, with a trunk up to 2 m diameter and a broadly conical to rounded or irregular crown.
is an important tree endemic to the western Mediterranean basin that it is able to grow in semi-arid climates. Aim: This work aimed to evaluate the biological activity of the leaf extracts of .
