the population densities and spatial distribution patterns of zetzellia pourmirzai khanjani and ueckermann and its preys cenopalpus irani dosse and bryobia rubrioculus (scheuten) were studied in a sprayed orchard in kermanshah, a western province of iran, from 31 may till 7 november, 2007. the interaction (density dependence) between the plant feeding mites and their predator was determined as ...

Seagrass shoots interact with hydrodynamic forces and thereby a positively or negatively influence the survival of associated species. The modification of these forces indirectly alters the physical transport and flux of edible particles within seagrass meadows, which will influence the growth and survivorship of associated filter-feeding organisms. The present work contributes to gaining insig...

The European Landscape Convention (ELC) has directed the landscape classification towards character analysis. analysis provides a character-based that can combine different values or variables and be applied at scales to define landscapes of each country forces on landscape. In this study, Kapısuyu Basin Küre Mountains National Park, which is one hot spots in world terms natural quality, was cl...

The proliferation of efficient fishing practices has promoted the depletion of commercial stocks around the world and caused significant collateral damage to marine habitats. Recent empirical studies have shown that marine reserves can play an important role in reversing these effects. Equilibrium metapopulation models predict that networks of marine reserves can provide similar benefits so lon...

Reduction of hydraulic conductance to the canopy has been shown to result in stomatal responses to limit transpiration. To test for similar responses to perturbations of the hydraulic network in leaves, we simultaneously measured leaf gas exchange with spatially explicit chlorophyll-a fluorescence and leaf temperature to examine the effects of cutting a primary leaf vein in Helianthus annuus. W...

Differentials between the invertebrate biodiversity of seagrass (S) and adjacent bare sediment (B) were investigated at 8 localities spaced along axial gradient an estuarine system, that Knysna in South Africa; various assemblage metrics being compared paired S/B stations. Little or no S:B differentials found near mouth, but significant increase those both levels overall abundance taxon richnes...
