The effects of rhizodeposition on soil C and N availabilities lead to substantial changes of microbial community composition and processes in the rhizosphere of plants. Under heterogeneous light, photosynthates can be translocated or shared between exposed and shaded ramets by clonal integration. Clonal integration may enhance the rhizodeposition of the shaded ramets, which further influences n...

Chemical profiling the sage essential oils (SEOs) from wild and cultivated (shaded or non-shaded) plants has been investigated. The yield of SEOs (3.51 mL/100 g) was higher than that plants(shaded plants: 3.20 g non-shaded 2.56 g).The main components SEO were cis-thujone (43.2%), camphor (17.6%), 1,8-cineole (13.8%), veridiflorol (3.8%) borneol (3.4%).The chemical composition included > 1,8-...

G. de Rham 1947, Un peu de math ematiques a propos d'une courbe plane, Elemente der Mathematik, 24:899104. 27 Figure 28: Each point in the shaded area carries a continuum of lines such that the associated aane standard cut produces C 1-curves without line segments. Hence for each contact point line one can nd a continuum of contact lines points such that either the associated p r ojective or aa...

Identifying the effects of stressors before they impact ecosystem functioning can be challenging in dynamic, heterogeneous 'real-world' ecosystems. In aquatic systems, for example, reductions in water clarity can limit the light available for photosynthesis, with knock-on consequences for secondary consumers, though in naturally turbid wave-swept estuaries, detecting the effects of elevated tur...

this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...

Effects of cluster exposure and winemaking treatments on freeand potential-volatile terpenes (FVT. P VT), total soluble solids (TSS), titratable acidity (TA), phenols pH, color and potassium were studied. Canopies of Golden Muscat grape vines were manipulated by shoot positioning and basal leaf removal at fruit set to create shaded and exposed cluster conditions. Winemaking treatments included:...

In three experiments, we explored how pigeons use edges, corresponding to orientation and depth discontinuities, in visual recognition tasks. In experiment 1, we compared the pigeon's ability to recognize line drawings of four different geons when trained with shaded images. The birds were trained with either a single view or five different views of each object. Because the five training views ...
