Despite renewed interest in the nature of limitations on maximum tree height, the mechanisms governing ultimate and species-specific height limits are not yet understood, but likely involve water transport dynamics. Tall trees experience increased risk of xylem embolism from air-seeding because tension in their water column increases with height due...
Daily temperature and salinity conditions measured in the surf at Agate Beach, Oregon are summarized by 15 day periods for 1968 and 1969. For each period the number of observations, the high, the low, the mean and the standard deviation of the temperature and salinity measurements are tabulated and figured....

military geography and terrain analysis and to examine these new research initiatives from that
perspective. Although the mobility and technological aspects of warfare have changed rapidly,
the essential geographic nature of warfare has remained...
Phytophthora infestans is a destructive plant pathogen best known
for causing the disease that triggered the Irish potato famine and
remains the most costly potato pathogen to manage worldwide.
Identification of P. infestan’s elusive center of origin is critical to
understanding the mechanisms of repeated global emergence of
this pathogen....

described in the context of a modification of Kates' Systems Model of
Human Adjustments to Natural Hazards for a small central Pennsylvania
town (1970 population=ll,O98) that became eligible for flood insurance
four months after experiencing five million dollars in flood damage
