1. introduction environmental changes can be monitored at many scales but the scale of landscape and region has more information in support of sustainable spatial planning. the availability of remote sensing imagery provides multi-scale observation with periodic repetitions over time. landscape and regional scales are adequately covered by satellite images. remote sensing images provide non-ave...

BACKGROUND Linking animal movements to landscape features is critical to identify factors that shape the spatial behaviour of animals. Habitat selection is led by behavioural decisions and is shaped by the environment, therefore the landscape is crucial for the analysis. Land cover classification based on ground survey and remote sensing data sets are an established approach to define landscape...

In most southern provinces of Iran, Soil Salinity is a growing problem particularly in the irrigated agricultural areas and has been found to reduce crop yields. In order to investigate the role of pod removal in seed germination, seedling growth and antioxidant enzymes activity in annual medics (Medicago scutella L.) under salinity stress conditions, a factorial experiment was conducted at Col...

Impacts of human land use pose an increasing threat to global biodiversity. Resource managers must respond rapidly to this threat by assessing existing natural areas and prioritizing conservation actions across multiple spatial scales. Plant species richness is a useful measure of biodiversity but typically can only be evaluated on small portions of a given landscape. Modeling relationships bet...

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...

With accelerated land-use change throughout the tropics, an increasing proportion of global biodiversity is located in human-modified landscapes. Understanding the relative effects of landscape composition and configuration on biodiversity is needed to design effective conservation strategies. Yet this topic is poorly understood because most studies have been performed at the patch scale, and d...
