ABSTRACT The Phoenician juniper (Juniperus phoenicea L.) has long been common in the Al-Akhdar mountain range in NE Libya. Juniper trees in the region are showing signs of dieback, and minimal successful seedling recruitment has occurred. We investigate this effect at the level of individual trees, tree size classes, and populations. At ten sites, population size, growth and reproductive traits, and percentage dieback in different size classes were evaluated. Elevation, distance from the sea… 
Demography of the threatened endemic shrub, Arbutus pavarii, in the Al-Akhdar mountainous landscape of Libya
We sampled twenty populations of the vulnerable endemic shrub or tree, Arbutus pavarii Pampan., at different elevations and aspects within the Al-Akhdar mountainous region of Libya. Our sampling
Population ecology of some keystone tree species in the Jebel Marra region of Darfur
The resilience potential of each species in the fallow lands indicated two distinct population resilience strategies: faster rebound in the case of A. amara and A. senegal and (2) slow recovery from disturbance in the cases of B. leiocarpus and B. aegyptiaca.
Ecological assessment of Juniperus turbinata Guss. forest on the Strofades Islands, Ionian Sea, Greece
The Strofades Islands form part of the National Marine Park of Zakynthos. Juniperus turbinata Gussone (syn. Juniperus phoenicea Linnaeus) forests are one of the few remaining high forest forms in
Clay and climatic variability explain the global potential distribution of Juniperus phoenicea toward restoration planning
Juniperus phoenicea is a medicinal conifer tree species distributed mainly in the Mediterranean region, and it is IUCN Red Listed species, locally threatened due to arid conditions and seed
10 A Size Distributionof Some Endangered Plant Species , Al-Jabal Al-Akhdar , Libya
L-JABAL Al-AkhdarMountainis the richest vegetation and .........highest species diversity in Libya. The aim of the present study was to evaluate the population structure of twelve endangered species
Potential Future Changes of the Geographic Range Size of Juniperus phoenicea in Algeria based on Present and Future Climate Change Projections
Abstract— MaxEnt (Maximum Entropy), a Species Distribution Modelling (SDM) method, was applied in the current study in order to assess present and future spatial distribution of the Phoenician
Global Change and Forest Disturbances in the Mediterranean Basin: Breakthroughs, Knowledge Gaps, and Recommendations
Forest ecosystems in the Mediterranean Basin are mostly situated in the north of the Basin (mesic). In the most southern and dry areas, the forest can only exist where topography and/or altitude
Plant communities and reproductive phenology in mountainous regions of northern Libya
Within the semi-desert landscape of northern Libya, two sub-humid escarpments occur: Al-Akhdar in the east and Nafusa (Jabal Al-Gharbi) in the west. This study compares plant communities in the two


The status and ecology of a Juniperus excelsa subsp. polycarpos woodland in the northern mountains of Oman
Juniperus excelsa subsp. polycarpos (K. Koch) Takhtajan is found in mountain areas from Turkey through to India and as an isolated population on Jebel Akhadar in the northern mountains of Oman.
The distribution and status of the montane juniper woodlands of Oman
The distribution, condition and reproductive status of Juniperus excelsa M. -Bieb. subsp. polycarpos (K.Koch) Takhtajan were determined and assessed in the Hajar mountains of northern Oman, Arabia.
Diplodia africana causing dieback on Juniperus phoenicea : a new host and first report in the northern hemisphere
Phoenicean juniper (Juniperus phoenicea L.) is a typical juniper found throughout the Mediterranean region. In Sardinia (Italy), this tree grows mostly at low altitudes close to the coast and in
Endangered stands of thuriferous juniper in the western Mediterranean basin: ecological status, conservation and management
Thuriferous juniper is only found in isolated parts of the western Mediterranean: France, Spain, Algeria and Morocco and conservation measures are urgently required to protect or rehabilitate these original stands with floristic, ecological and socio-economic interest.
Cyrenaica is the largest phytogeographical region in Libya. The region holds Al-Jabal Al-Akhdar (the Green Mountain) landscape with the richest vegetation and highest species diversity in the
Unravelling the architecture of functional variability in wild populations of Polygonum viviparum L.
This study seeks to assess the relative roles of abiotic stress and biotic interactions in shaping different aspects of functional variation within and among populations, that is, the multi-trait variability, the strength of correlations between traits, and the main directions of functional trade-offs.
Genetic variation in five Mediterranean populations of Juniperus phoenicea as revealed by inter-simple sequence repeat (ISSR) markers.
The results indicate that geographical isolation has represented a major barrier to gene flow in Juniperus phoenicea, a first step towards a full genetic characterization of a conifer from the Mediterranean, a world biodiversity hotspot confronted with climate change.
