The Wind Cave National Park Elk Herd: Home Ranges, Seasonal Movements, And Alternative Control Methods, Peter Bauman Jan 1998

The Wind Cave National Park Elk Herd: Home Ranges, Seasonal Movements, And Alternative Control Methods, Peter Bauman

Electronic Theses and Dissertations

Elk (Cervus elaphus ne/soni) herd organization, movements, and home range size in Wind Cave National Park (WICA) were studied from May 1996 to August 1997. Twenty radiocollared elk ( 10 males, 10 females) were relocated by ground and aerial telemetry. Radiocollared elk were relocated two times/week, resulting in 1,595 relocations ( 410 ground, 1, 185 aerial). Coefficients of association (CA) for radiocollared cows averaged 0.005 during spring/summer 1996, 0.033 during spring/summer 1997, and 0.295 during falVwinter 1996. Coefficients of association for radiocollared bulls averaged 0.011 during spring/summer 1996, 0.015 during spring/summer 1997, and 0.075 during faIVwinter 1996. Three cow subherds …


Owls Of The Idaho National Engineering And Environmental Laboratory (Ineel), Natalie A. Fahler Jan 1998

Owls Of The Idaho National Engineering And Environmental Laboratory (Ineel), Natalie A. Fahler

Electronic Theses and Dissertations

The Idaho National Engineering and Environmental Laboratory (INEEL) is a 2,315 km2 energy research and development site located on the Upper Snake River Plain of Southeast Idaho. Owl research was conducted on the site during the spring and summers of 1996-1997. Objectives were to: a) determine productivity, habitat use, and possible nest site selection factors of burrowing owls (Athene cunicularia ), b) verify the presence of small owl species including the boreal owl (Aegolius funereus), the northern saw-whet owl (A. acadicus), the western screech owl (Otus kennicottii), the flammulated owl (0. flammeolus), and the northern pygmy owl (Glaucidium gnoma), c) …


Passerine Use Of Grasslands Managed With Two Grazing Regimes On The Missouri Coteau In North Dakota, Natoma A. Schneider Jan 1998

Passerine Use Of Grasslands Managed With Two Grazing Regimes On The Missouri Coteau In North Dakota, Natoma A. Schneider

Electronic Theses and Dissertations

Several rotational grazing systems have been implemented on the Missouri Coteau in central and northcentral North Dakota as part of the Prairie Pothole Joint Venture (PP N). The impacts these systems have on grassland passerines are not fully understood. Objectives for this study include determining relative abundance, species composition and reproductive success of passerines as well as vegetation characteristics for rotational and traditional season-long grazing regimes. Passerine relative abundance and species richness were determined on rotational grazing systems during 1995-1997 and on season-long grazed pastures during 1996-1997 using 122 fixed, 100 m radius, point counts. Relative abundance was assessed by …


An Implementation Of The El Gamal Elliptic Curve Cryptosystem Over A Finite Field Of Characteristic P, Samuel Thomas Arslanian Jan 1998

An Implementation Of The El Gamal Elliptic Curve Cryptosystem Over A Finite Field Of Characteristic P, Samuel Thomas Arslanian

Electronic Theses and Dissertations

Since the earliest times, individuals and groups of individuals have been interested in communicating sensitive information in a manner which would guarantee that such information could not be arbitrarily received. Further, such information was to be received by select recipients and this required that a means of secure information transmission be found and employed. To these ends, methods of information encryption have ever since been sought and employed. The entire study and practice of this activity, cryptology, the science of message encryption and decryption, provides a framework for this thesis. In particular, the development of cryptology has been influenced by …
