plants change their environment characteristics and especially soil properties while their growth and adaptation, to develop plant communities. in this study effect of halophyte patches from urmia lack in a vegetation type of salsola nitraria and aeluropus littoralis on chemical and physical properties of soil was investigated. so 4 vegitation patches along 2 transect with the length of 150 met...

Transdermal patches are now widely used in topical and transdermal drug delivery systems (TDDS). Up to now, TDDS has been used in several conditions, such as smoking cessation, analgesic effect, nausea, contraception, and hormone therapy. Basically, there are two types of transdermal patches: the reservoir-type patches and the matrix-type patches. First generation TDDS were designed for deliver...

Conserving landscape connections among favorable habitats is a widely used strategy to maintain populations in an increasingly fragmented world. A species can then exist as metapopulation consisting of several subpopulations connected by dispersal. Our study focuses on the importance human–wildlife coexistence areas maintaining connectivity primary small ungulates within and outside protected l...

introduction urban landscape is experiencing rapid changes which put all urban domains under pressures. these processes revolutionize urban landscape into spaces without ecologic values. the sustainability of green patches and corridors has been scathed by lack of ecological approaches in planning and design. therefore, urban green spaces structures and functions have been damaged. green spaces...

The persistence of forest-dependent species in fragmented landscapes is fundamentally linked to the movement of individuals among subpopulations. The paths taken by dispersing individuals can be considered a series of steps built from individual route choices. Despite the importance of these fine-scale movement decisions, it has proved difficult to collect such data that reveal how forest birds...

Corridors are important geographic features for biological conservation and biodiversity assessment. The identification and mapping of corridors is usually based on visual interpretations of movement patterns (functional corridors) or habitat maps (structural corridors). We present a method for automated corridor mapping with morphological image processing, and demonstrate the approach with a f...

Riparian zones are of utmost importance in providing a wide range of ecological and societal services. Among these, their role in maintaining landscape connectivity through ecological corridors for animals and plants is of major interest from a conservation and management perspective. This paper describes a methodology to identify European regions as providers of structural riparian corridors, ...
