The mechanism of water-stress-induced xyletn embolism was studied in three species of conifers: Abies balsamca (L.) Mill., Picea rtibens Sarg. and ./uniperus virginiana L. Each species showed a characteristic relationship between xylem tension and the loss of hydraulic conductivity by air etnbolistn. Abies balsamea and Picea rubens began to etnbolize at tensions between 2 and 3 MPa and were com...

Fruit and leaves of junipers are commonly used internally as tea and pounded fruits are eaten to lower blood glucose levels in Anatolia. Thus, we aimed to evaluate antidiabetic and antioxidant potential and the chemical profile of Juniperus foetidissima Willd. and J. sabina L. in this study. In-vitro antidiabetic activities of leaf and fruit extracts were examined by their inhibitory activity o...

Mismatches between invasive species management policies and ecological knowledge can lead to profound societal consequences. For this reason, natural resource agencies have adopted the scientifically-based density-impact invasive species curve to guide invasive species management. We use the density-impact model to evaluate how well management policies for a native invader (Juniperus virginiana...

The objective of this work was to map population common juniper (Juniperus communis L.) in the territory Slovak Republic. Common is not protected by Slovakian law or authorities; therefore, there no preserve these plant populations. Biotopes consist light- heavy-density trees and shrubs. expansion its habitat also connected human involvement. loss naturally observed plants caused a change land ...

• While studies of modern plants indicate negative responses to low [CO2] that occurred during the last glacial period, studies with glacial plant material that incorporate evolutionary responses are rare. In this study, physiological responses to changing [CO2] were compared between glacial (La Brea tar pits) and modern Juniperus trees from southern California. • Carbon isotopes were measured ...
