India led the global tiger conservation initiatives and has doubled its wild population to 2967 (2603–3346) since 2006. As extant habitats are shrinking continuously, persistence of these growing populations can only be ensured through focused landscape-scale planning across all existing landscapes Indian. We used intensive field-sampling, genetic analyses GIS modelling investigate structure, s...

Popcorn fractals are instances of Integrated Fractal Systems involving trigonometric functions. In this paper, we study the effect of spherical, swirl and pseudo-horseshoe functions on popcorn fractals to produce talismanic and tantric designs. General Terms Fractal, Algorithm, Turbo C++, Program.

landscape fragmentation has threatened the landscape continuity of ray which was maintainedfrom prehistoric times until recent decades. from 19th century that tehran sprawl growth affected ray’slandscape as a satellite city of tehran, ray experienced rapid landscape fragmentation and underwent manychanges. in order to cope with the threat, the process of changes from landscape fragmentation sho...

One of the most significant threats to biodiversity is alien species invasion, and consequently understanding predicting biological invasions has become an important issue in ecology. While numerous studies have explored effect community diversity structure on invasion success, a systematic comparative analysis system robustness between antagonistic mutualistic networks from metacommunity persp...

Cognitive ecology is a term that has been used in environments that are more tightly coupled and purposespecific than environments of everyday life. In this paper I consider cases from a cognitive ethnography of older adults. These cases show the analytical use of understanding the diachronic and synchronic cognitive ecology in which cognitive processes of everyday life occur. Specifically I di...
