Resource selection and space use of the critically endangered Tuamotu Kingfisher (Todiramphus gambieri)
(University of Missouri--Columbia, 2010)
I investigated the ecological requirements of the critically endangered Tuamotu Kingfisher (Todiramphus gambieri), with the intent to provide management recommendations that could help prevent its extinction. The species ...
A test of differential GPS correction methods at Fort Huachuca, Arizona
(University of Missouri--Columbia, 2009)
in differential correction has previously proven unreliable. The effectiveness of base data acquired through use of a second field unit as an on-site base station was compared with the use of CORS. The accuracy of data differentially corrected using base data...
A multi-scale investigation of ecologically relevant effects of agricultural runoff on amphibians
(University of Missouri--Columbia, 2008)
Modification of landscapes for agricultural production can introduce agrochemicals into surface waters and degrade aquatic habitats used by many amphibians for breeding and larval development. Although many ecotoxicological studies have shown...
