The relationships between the fruit features of Juniperus communis and the presence of fruit pests were studied in Sierra Nevada, SE Spain. The abundance of two insect species a pulp-sucking scale and a seed-predator wasp was surveyed with respect both to fruit characteristics and to viability of seeds contained therein. Seed-predator pressure was not significantly related to any fruit characte...

• A central aim of biogeography is to understand when and how modern patterns of species diversity and distribution developed. Many plant groups have disjunct distributions within the Northern Hemisphere, but among these very few have been studied that prefer warm semi-arid habitats. • Here we examine the biogeography and diversification history of Juniperus, which occurs in semi-arid habitats ...

Recently, we reported a novel access to 2,2-diethyl-3-[(E/Z)-prop-1-en-1-yl]cyclobutanone by an intramolecular nucleophilic substitution with allylic rearrangement (S(N)i') of (E)-6-chloro-3,3-diethylhept-4-en-2-one. The ring closure reaction was found to proceed with selective syn-displacement of the leaving group. This method was now applied to the total synthesis of junionone, an olfactorily...

Although considered rare, airborne pollen can be deposited far from its place of origin under a confluence of favorable conditions. Temporally anomalous records of Cupressacean pollen collected from January air samples in London, Ontario, Canada have been cited as a new case of long-distance transport. Data on pollination season implicated Juniperus ashei (mountain cedar), with populations in c...

Responses of American arborvitae (Thuja occidentalis), common yew (Taxus x media) and juniper (Juniperus communis) to enhanced UV-B irradiance were studied. Control plants were grown without UV treatment, but at identical PhaR and temperature regimes. Visual symptoms of the ultraviolet effect noted on Thuja shoots as brown/red discolouration were correlated with the accumulation of phenolic com...

Twelve individual genotypes selected from Juniperus populations, varieties and species were analyzed using ITS sequences, RAPDs, ISSRs, and leaf volatile terpenoids. These four data sets, all analyzed in the same manner, illustrated that these data sets can be used at different organizational levels: specific, inter-specific and intraspecific. Similarity matrices for the ITS, RAPD, and ISSR dat...

Juniper volatile oil is extracted from Juniperus communis L., of the Cupressaceae family, also known as common juniper. The therapeutic properties of juniper oil are antiseptic, antirheumatic, antispasmodic, astringent, carminative, depurative, diuretic, rubefacient, stimulating, stomachic, sudorific and tonic. In traditional medicine, juniper oil was used to relieve anxiety, nervous tension an...
