According to the prevailing hypothesis, the distance that these fishes graze sea grass is limited by the abundance of predator fishes in the area.
As emissions are forced into the atmosphere, however, they react with water molecules and then are often blown great distances by prevailing winds, which in the United States tend to move from west to east.
They are easily carried long distances by prevailing winds and can lead to epidemics.
The relation between Hg inventories (normalized for prevailing wind direction) and distance from the smelter was used to estimate the total Hg fallout within a 50 km radius in 5 year time-steps, thus providing a quantitative spatial-temporal Hg depositional history for the Flin Flon region.
Monitoring consisted of transects 4 16 km in length, nearly perpendicular (i.e., N S) to the direction of the prevailing winds, at varying downwind distances.
Peter Coe recognized that the prevailing coaching methods for middle-distance racing in Britain were outmoded, and he revolutionized the program for his son by focusing on repetitious speed work rather than longer, slower sessions.
Globalization has not eliminated the significance of distance or of prevailing emotional attachments.
Another case-control study, which found that residential petrochemical exposure was a significant risk factor for leukemia in persons of age 20 29 years, used a composite exposure proxy taking account of distance, time, and prevailing wind direction [ 11].
Most studies having looked at health outcomes in relation to distance to major roads did not take into account prevailing wind directions and used the same distance thresholds for both sides of a major road.
Physical activity and over-weight have not received much importance in the daily life of the urban population in Africa due to the prevailing inadequate road infrastructure necessitating long distance walking on a daily basis.
