Several studies have been conducted in the past to clarify various aspects of species genus Juniperus L. One critical group is oxycedrus L., especially from taxonomical point view. For this reason, we studied ecology, taxonomy and distribution taxa J. group. From an ecological standpoint, work use ombroedaphoxeric index (Ioex) explain presence populations ombrotypes that are not optimum for the...

Analyses of individuals classically treated as Juniperus oxycedrus L. var. oxycedrus from Morocco, Portugal, Spain, France, Italy, Greece and Turkey, using DNA sequencing of nrDNA (ITS 1, 5.8S, ITS 2) plus RAPDs, leaf terpenoids and morphology revealed that two cryptic, genetically distinct but morphologically almost identical species are present. These species, J. oxycedrus L. var. oxycedrus a...

A hydrocarbon that is widespread in Juniperus foliage was isolated from Juniperus erectopatens (Cheng and L. K. Fu) R. P. Adams and identified as (E,E,E)-1,7-dimethylcyclodeca-1,4,7-triene (pregeijerene B). Geometry of the disubstituted double bond was determined by IR and NMR spectroscopy, while that of the trisubstituted double bonds was proven by comparison of the products of selective hydro...

Plants of Juniperus communis L. var. communis, J. c. var. depressa Pursh, J. c. var. jackii Rehdr, J. c. var. saxatilis Pall. were sampled and SNPs from nrDNA were examined. Based on these data and previous data, a new variety of J. communis is recognized: Juniperus communis var. charlottensis R. P. Adams, var. nov. It occurs in muskeg bogs on Queen Charlotte Island, British Columbia and in the...

A study was conducted on the aphid fauna of Pinus nigra Arnold. subsp. pallasiana (Lamb.) Holmboe., brutia Ten., Cedrus libani A. Rich., Abies cilicica (Antoine & Kotschy) Carrière (Pinaceae), Juniperus spp. (Cupressaceae), Quercus (Fagaceae) and Robinia pseudoacacia L. (Leguminosae) forests in Isparta Province between 2018 2020. Using systematic random sampling, 9,252 specimens 68 spec...
