The overall objective of this research is to develop a comprehensive vegetation classification and management system for Cedar Breaks National Monument. Specific Objectives are: 1. To complete an inventory of current community types, habitat types, distribution of rare of endangered plant species and the potential habitat for these same species, and the distribution and dynamics of exotic plant species found inside the Monunent; and 2. To develop an ecologically-based landscape succession model to serve as a comprehensive predictive tool for use in managing the vegetation resources in Cedar Breaks National Monument.

The objectives of this study, initiated in May, 1978, were to study and delimit the habitat types of Theodore Roosevelt National Memorial Park (TRNMP), North Dakota, to collect and tabulate the vascular plants, to determine the edaphic characteristics of the habitat types, and to collect animal species of the habitat types. There have been few studies of habitat types in grassland areas; this one is the first in western North Dakota. The habitat type concept was developed to assess the ecologic status of forest vegetation of the Northern Rocky Mountains (Daubenmire 1952, Daubenmire and Daubenmire 1968). Later Daubenmire (1970) used the same concepts in an analysis of steppe vegetation of eastern Washington. This basic ecologic concept has been used since in a number of studies throughout the Rocky Mountain region (Pfister et al. 1977, Reed 1971, 1976, Wirsing and Alexander 1975, Hoffman and Alexander 1976). The basic nature of this ecologic concept permits wide usage in vegetation studies. Additionally, following the basic habitat type delimitation, follow-up studies can relate the habitat types to other aspects of the biotic community. Examples include studies on primary productivity, disease susceptibility of tree species, potential for wildlife, soil moisture regimes, small mammal distributions (Daubenmire 1973, Hoffman 1960, Layser 1974, Mackee 1970, Rickard 1960).

Type Concept

The objectives of this study, begun in May 1978, are to delimit the habitat types of Theodore Roosevelt National Memorial Park (TRNMP), North Dakota, list the plants present, and assess the animal components of the habitat types. For TRNMP a comprehensive study of the habitat types has not been done previously. The habitat type concept was developed to assess the ecologic status of forest vegetation of the Northern Rockies (Daubenmire 1952, Daubenmire and Daubenmire 1968); and the same concept was later used to assess steppe vegetation of Washington (Daubenmire 1970). The habitat type approach to assessing the ecologic status of vegetation has been used in a number of studies throughout the Rocky Mountain region (Pfister et al. 1977, Reed 1971, 1976, Wirsing and Alexander 1975, Hoffman and Alexander 1976). The basic ecologic nature of the habitat type concept lends itself to studying forest and grassland vegetation as well as interspersed shrublands (Daubenmire 1973). It has been shown that once established for a given region, habitat types provide the framework for establishing relationships between the habitat types and productivity, disease susceptibility, potential for forage production, soil moisture relations, and small mammal distributions (Daubenmire 1973, Hoffman 1960, Layser 1974, Mackee 1970, Rickard 1960). The study at TRNMP will provide data on habitat types and their major animal components and will offer opportunity for future assessment of soil moisture relations, productivity and other characteristics of a basic or applied nature.

Gambella National Park has a diverse set of habitat types which Ethiopia shares with its neighbor, South Sudan, and the park is considered as one of the top wildlife areas of Ethiopia. The objectives of this research were to determine vegetation types and identify habitat types on recent satellite imageries. The method used for vegetation data collection was transects lines. PC-ORD software was used for analyzed vegetation data while Rapid Eye image 5 m resolution 2012 was analyzed by ArcGIS version 10.1 to classify the habitats map of Gambella National Park. The cluster analysis classified the Gambella National Park into 6 vegetation communities, and the relative abundance and relative frequency were used for naming vegetation community types. However, the satellite image had classified the Gambella National Park into 5 major habitat types.

Rickettsia Rickettsii

Eine 37-jährige Patientin stellt sich nach der Rückkehr von einer Rundreise durch Nordamerika mit einem Status febrilis seit zehn Tagen und einem makulösem extremitätenbetontem Exanthem seit einem Tag vor. Bei suggestiver Klinik und Besuch der Rocky Mountains wird ein Rocky Mountain spotted fever diagnostiziert. Die Serologie für Rickettsia conorii, die mit Rickettsia rickettsii kreuzreagiert, war positiv und bestätigte die klinische Diagnose. Allerdings konnte der beweisende vierfache Titeranstieg, möglicherweise wegen spät abgenommener ersten Serologie, nicht nachgewiesen werden. Nach zweiwöchiger antibiotischer Therapie mit Doxycycline waren Status febrilis und Exanthem regredient.
