During the winters of 2013-2014 and 2014-2015, anomalously warm temperatures in western North America and anomalously cool temperatures in eastern North America resulted in substantial human and environmental impacts. Motivated by the impacts of these concurrent temperature extremes and the intrinsic atmospheric linkage between weather conditions in the western and eastern United States, we inv...

West Nile virus was first detected in North America in 1999 and has subsequently spread throughout the United States and Canada and into Mexico and the Caribbean. This review describes the epidemiology and ecology of West Nile virus in North America and the prospects for effective treatments and vaccines.

West African Aspergillus flavus S isolates differed from North American isolates. Both produced aflatoxin B1. However, 40 and 100% of West African isolates also produced aflatoxin G1 in NH4 medium and urea medium, respectively. No North American S strain isolate produced aflatoxin G1. This geographical and physiological divergence may influence aflatoxin management.

14,849 affected cases of beta thalassemia have been registered in 1995 in all provinces of iran. it is estimated that there are about three million carriers in iran. the provincial distributions of the affected cases show that the highest incidence in 100 thousand individuals was in mazandaran (71.29) and gilan (57.61), respectively, both near the caspian sea (north), followed by hormozgan (50....

The growing development of offshore wind energy installations across the North Sea is producing new hard anthropogenic structures in the natural soft sediments, causing changes to the surrounding macrobenthos. The extent of modification in permeable sediments around a gravity based wind turbine in the Belgian part of the North Sea was investigated in the period 2011-2012, along four gradients (...

How the spatial expansion of a species changes at a human time scale is a process difficult to determine. We studied the dispersal pattern of the French white stork population, using a 21-year ringing/resighting dataset. We used the graph-theory to investigate the strength of links between 5 populations (North-East, North-West, Centre, West, and South) and to determine factors important for the...
