western parts of the chaharmahal and bakhtiyari province (ardal county) due to containing high mountains, deep valleys and small intermountain plains as well as the placement in the path of the nomads have long been of interest to humans. the nomadic communities of the mountainous regions of chaharmahal va bakhtiyari culturally interacted with the lowland areas of fars and khuzestan's plai...

We study the effect of the life settlement market on the structure of long term contracts offered by the primary market for life insurance, as well as the effect on consumer welfare, using a dynamic model of life insurance with one sided commitment and bequest-driven lapsation. We show that the presence of life settlement affects the extent as well as the form of dynamic reclassification risk i...

Coral settlement is a key ecological process in the maintenance, recovery and resilience of coral reef ecosystems. Coral reefs in the Persian Gulf survive in one of the world’s most extreme environments, yet there remains limited knowledge of the role of coral settlement considered critical for maintaining population dynamics. Spatial and temporal patterns of coral settlement were examined at 6...

For sessile marine invertebrates, processes contributing to larval release, dispersal, and settlement in favourable habitats are central to patterns of distribution and community structure. We quantified larval release patterns, phototactic behaviour, and settlement in response to environmental cues for the coral reef sponge Luffariella variabilis. Individual sponges released up to 830 larvae d...

Both ecological and social factors play an important role in determining the structure of animal settlement patterns. While the ecological factors determining animal settlement are generally well known, the relative importance of social factors in mediating fine-scale settlement choices is poorly understood. As a result, we have little knowledge of why individuals choose to settle near specific...
