We link spatially explicit climate change predictions to a dynamic metapopulation model. Predictions of species' responses to climate change, incorporating metapopulation dynamics and elements of dispersal, allow us to explore the range margin dynamics for two lagomorphs of conservation concern. Although the lagomorphs have very different distribution patterns, shifts at the edge of the range w...
Meningococcal infection has been recognized as a serious problem for almost 200 years. Cerebrospinal or Meningococcal meningitis (MCM) can occur as a sporadic case, institution based focal outbreak, or a large epidemic year. The distribution of serogroups causing meningococcal disease (A, B, C, Y, W-135) varies over time and by geographic location and spatial distribution of the disease indicat...
The Laurentian Great Lakes Basin provides an ecological system to evaluate the potential effect of climate change on dynamics of fish populations and the management of their fisheries. This review describes the physical and biological mechanisms by which fish populations will be affected by changes in timing and duration of ice cover, precipitation events and temperature regimes associated with...
Current emissions of anthropogenic greenhouse gases (GHGs) have already committed the planet to an increase in average surface temperature by the end of the century that may be above the critical threshold for tipping elements of the climate system into abrupt change with potentially irreversible and unmanageable consequences. This would mean that the climate system is close to entering if not ...
Understanding and predicting species distribution in space and time and consequently community structure and dynamics is an important issue in ecology, and particularly in climate change research. A crucial factor determining the composition and dynamics of animal populations is habitat heterogeneity, i.e., the number of structural elements in a given locality. In the marine pelagic environment...
Ambitious climate mitigation policies face social and political resistance. One reason is that existing insufficiently capture the diversity of relevant insights from sciences about potential policy outcomes. We argue agent-based models can serve as a powerful tool for integration elements different disciplines. Having such common platform will enable more complete assessment policies, in terms...
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
Climate and the required parameters for agricultural products are the important factors of production. We can determine potential facilities in different areas and consider the maximum tapping through agricultural meteorology. Due to drylands potentials in Hamedan province, we conducted a comprehensive survey based on 20 years (1995-1995) climatic elements of 9 main and supplementary synoptic s...
The process regarding the formation of different mosque gardens and the elements that contribute to the respective process is the from the foci point of this paper. The significance of the topic lies in the fact that certain scholars have associated the courtyard in mosques with the concept of garden, and have not taken into account the elements that contribute to the development of various typ...
1 INTRODUCTION As the fi nancial crisis continues to take its toll on the global economy, another serious challenge looms large: preventing the planet from warming more than 3.6 degrees Fahrenheit. Policymakers are now faced with the daunting task of stimulating growth without using carbon-intensive practices and stabilizing the climate without dampening economic recovery. If the fi nancial cri...
