Wild rodents were collected using live snap traps in pistachio gardens of Kerman Province, Southeast Iran from 2007 to 2009, then some physiological parameters of them were measured. The samples were identified as follow: Nesokia indica, Meriones persicus, Meriones lybicus and Tatera indica. Blood samples were obtained from the heart, then the blood parameters (glucose, cholesterol, triglyceride, total protein, HDL, red and white blood cell number) in wild species of rodents and laboratory rat were compared. The results showed that there were no significant differences in serum glucose, triglyceride, HDL and total protein levels among different experimental groups. The concentration of cholesterol in T. indica was more than that in N. indica (P < 0.01). The total numbers of red blood cells also showed significant difference between wild garden rodent species and laboratory rat (P < 0.01), while the numbers of white blood cells showed no significant difference. 相似文献

Developing a spatial framework of common ecological regions for the conterminous United States 总被引:4,自引:1,他引:4

In 1996, nine federal agencies with mandates to inventory and manage the nation's land, water, and biological resources signed
a memorandum of understanding entitled “Developing a Spatial Framework of Ecological Units of The United States.” This spatial
framework is the basis for interagency coordination and collaboration in the development of ecosystem management strategies.
One of the objectives in this memorandum is the development of a map of common ecological regions for the conterminous United
States. The regions defined in the spatial framework will be areas within which biotic, abiotic, terrestrial, and aquatic
capacities and potentials are similar. The agencies agreed to begin by exploring areas of agreement and disagreement in three
federal natural-resource spatial frameworks—Major Land Resource Areas of the US Department of Agriculture (USDA) Natural Resources
Conservation Service, National Hierarchy of Ecological Units of the USDA Forest Service, and Level III Ecoregions of the US
Environmental Protection Agency. The explicit intention is that the framework will foster an ecological understanding of the
landscape, rather than an understanding based on a single resource, single discipline, or single agency perspective. This
paper describes the origin, capabilities, and limitations of three major federal agency frameworks and suggests why a common
ecological framework is desirable. The scientific and programmatic benefits of common ecological regions are described, and
a proposed process for development of the common framework is presented. 相似文献
