Most risk analysis studies in invasion biology have focused on the invasiveness of non-native species, even though some native species also can pose a high to environment and human well-being. This is especially true under current global change, which may cause dominant expand their range distribution substantial effects ecosystem. In this study, five plant Turkey was evaluated using standard s...

In this paper, we define X-slant helix in Euclidean 3-space and we obtain helix, slant helix, clad and g-clad helix as special case of the X-slant helix. Then we study Darboux, tangential darboux developable surfaces and their singular points. Especially we show that the striction lines of these surfaces are singular locus of the surfaces.

La flora urbana, puede ser reservorio de biodiversidad, o fuente invasiones según criterios selección. Objetivos: Se estimó riqueza especies, formas vida, familias botánicas orige...

Many things change during shoot development. Although the most obvious of these is the production of reproductive structures, the morphology and physiology of leaves and vegetative buds changes as well. Some traits change continuously (either increasing or decreasing), while others are expressed in bimodal (present or absent) or even more complex patterns. Some traits vary in the same way in ev...

Materials and Methods ― Fodder and fecal samples were collected from 3 groups of 3 goats, browsing ad lib on fresh leafy Quercus pubescens branches. The 3 groups were made up of: 3 dried-up animals without supplementation; 3 lactating animals, supplemented with a urea-molasses mixture, in a digestibility cage (Meuret, 1988); and 3 lactating animals compelled to eat a pure 0 pubescens die...

Introduction. Among nonantibiotic cough remedies, herbal preparations containing extracts from leaves of ivy (Hedera helix) enjoy great popularity. Objective. A systematic review to assess the effectiveness and tolerability of ivy for acute upper respiratory tract infections (URTIs). Methods. We searched for randomized controlled trials (RCTs), nonrandomized controlled clinical trials and obser...

BACKGROUND Colorectal cancer has become one of the leading cause of cancer morbidity and mortality throughout world. Hederagenin, a derivative of oleanolic acid isolated from the leaves of ivy (Hedera helix L.), has been shown to have potential anti-tumor activity. The study was conducted to evaluate whether hederagenin could induce apoptosis of human colon cancer LoVo cells and explore the pos...
