jajrood protected complex (khojir and sorkheh hesar national parks and jajrood protected area) is one of the most important habitats of central alborz wild sheep (ovis gmelini x o. vignei) in iran. since the species mate in fall, then fall home range has critical rule in life cycle of this species. using the ecological niche factor analysis (enfa), effective factors on the presence of species w...

gharaviz no hunting area is known as one of the most important habitats of persian gazelle (gazella subgutturosa subgutturosa) in west zagros mountains. developing models to predict the distribution of wildlife is suitable tool for conservation and management. in this approach, the boundary of the study area was considered the distribution area and then were compared with actual region. field d...

Habitat modelling and predictive mapping are important tools for conservation planning, particularly for lesser known species such as many insectivorous bats. However, the scale at which modelling is undertaken can affect the predictive accuracy and restrict the use of the model at different scales. We assessed the validity of existing regional-scale habitat models at a local-scale and contrast...

Niche description and differentiation at broad geographic scales have been recent major topics in ecology and evolution. Describing the environmental niche structure of sister taxa with known evolutionary trajectories stands out as a useful exercise in understanding niche requirements. Here we model the environmental niche structure and distribution of the recently resolved phylogeography of gu...

C4 photosynthesis is a physiological innovation involving several anatomical and biochemical components that emerged recurrently in flowering plants. This complex trait evolved via a series of physiological intermediates, broadly termed 'C3-C4', which have been widely studied to understand C4 origins. While this research program has focused on biochemistry, physiology, and anatomy, the ecology ...

Spatio-temporal modelling of the distributions of the leishmaniases and their sandfly vectors is reviewed in relation to climate change. Many leishmaniases are rural zoonoses, and so there is a foundation of descriptive ecology and qualitative risk assessment. Dogs are widespread reservoir hosts of veterinary importance. Recent statistical modelling has not always produced novel general conclus...
