the images of muslims in media, literature and politics have been mostly black and white portrayals of a people alien to modernity, civilization, rationality and pluralism. since the end of the cold war and the onset of deadly terrorist attacks in different areas of the world, especially in the united states, these representations show a palpable difference: muslims are represented not only as ...

basins leading to tabriz plain are part of the sub-basins of urmia lake basin, which is located in the east azerbaijan province and in the north-western part of iran. the area of this basin is 5397 km2, and agriculture is one of the main sources of income for the people, which is dependent on groundwater and surface water resources. in this study, an attempt was made to investigate the basins l...

Habitat fragmentation can change the community composition of species in remnant habitat patches. We studied the impacts of fragmentation by agriculture on the bird community in heavily fragmented areas of the sagebrush shrubsteppe in western North America. We examined whether bird communities in sagebrush habitat near orchards and vineyards were different from the community in interior sagebru...

The population of loggerhead shrike (Lanius ludovicianus excubutirudes) in Grassland National Park of Canada (GNPC) has undergone a severe decline due to habitat loss and limitation. Shrike habitat availability is highly impacted by the biophysical characteristics of grassland landscapes. This study was conducted in the west block of GNPC. The overall purpose was to extract important biophysica...

For rare and endangered species, bioenergetics modeling can represent a valuable approach for understanding issues of habitat value and connectivity among potential habitats within nurseries in restoration programs. We used multivariable bioenergetics and survival models for Atlantic sturgeon to generate spatially explicit maps of potential production in the Chesapeake Bay. For the period 1993e...

The objective of our work was to verify the value of the vegetation corridor in the conservation of small mammals in fragmented tropical landscapes, using a model system in the southeastern Minas Gerais. We evaluated and compared the composition and structure of small mammals in a vegetation corridor, forest fragments and a coffee matrix. A total of 15 species were recorded, and the highest spe...

learning-oriented assessment seeks to emphasise that a fundamental purpose of assessment should be to promote learning. it mirrors formative assessment and assessment for learning processes. it can be defined as actions undertaken by teachers and / or students, which provide feedback for the improvement of teaching and learning. it also contrasts with equally important measurement-focused appro...

—We assessed the precision of visual estimates of vegetation and substrate along transects in 15 shallow, natural Nebraska lakes. Vegetation type (submergent or emergent), vegetation density (sparse, moderate, or dense), and substrate composition (percentage sand, muck, and clay; to the nearest 10%) were estimated at 25–70 sampling sites per lake by two independent observers. Observer agreement...

Habitat suitability models for the focal species are used to address the concerns related to the limited availability of data for remote habitats by scrutinizing the relationship between the biodiversity distribution patterns and the natural-anthropogenic characteristics. The current study aimed at modeling habitat suitability for seven focal species including Asian black bear, Persian leopard,...
