RECOVERY OF MIDWESTERN PRAIRIES FROM DROUGHT JOHN E. WEAVER University of Nebraska (Read Novem ) THE long period of desiccation, which began infinally terminated in The western portion of True Prairie was greatly decimated and a veritable mosaic of types of vegetation resulted.
Because droughts of this intensity occur about every 50 years in the prairie, periodic drought may have limited prairie diversity.
Cover of true prairie grasses increased from less than 5 to. The water relations and growth of three tallgrass prairie species Panicum virgatum, Andropogon gerardii and A. scoparius were examined in irrigated and unwatered prairie in eastern Kansas (USA).
Measurements of the osmotic potential at full turgor, ψ πat zero turgor, ψ0, and growth of vegetative and reproductive tillers were made in a year with above-normal precipitation and Cited by: Fehrenbacher and Alexander () mapped three vegetation types in relation to soil associations.
In addition to prairie and forest, mixed forest and prairie occurred primarily on terraces and bottomlands along many of the major streams and in narrow bands between true prairie and true forest soils.

Plant bugs apparently declined while predaceous dam- sel bugs increased during the summer following spring burning on Kansas true prairie (Nagel, ). After 7 years of fire exclusion, a spring burn signifi- cantly reduced hemipteran numbers for at least 6 months on a limestone grass- Cited by: Third, the paleoecological approach is especially suited for long-lived organisms.
For example, a tree species that may typically reach reproductive sizes only after 50 years and remain fertile for years, will experience only 30 to generations since colonizing a location after Holocene warming ab years ago.
[ Home] The semidesert grassland complex of climax range communities comprises the most xeric grasslands in North America. There are two larger and more general regions of semidesert grassland in North America both of which are associated with the Basin and Range physiographic province and major climatic deserts therein.
At the beginning of the Holocene, about 11 years B.C., right after the so called Flandrian transgression the riverbed underwent significant changes, (Popov, ). According to a palinological research, Lake Srebarna has been formed about 8 years ago following the inundation of the riverside terrace by the Danube (Bozilova, Lazarova.TERI (The Energy and Resources Institute) is a not-for-profit, research organization working in the fields of energy, environment, and sustainable development.

The deepening insights into the nature of man and his diverse living kin could well be reward enough for the large investment of effort and funds. Such understanding is more than a highlight of our culture; it is a primary tool of our working civilization.
