Development and evaluation of a terrestrial animal-borne video system for ecological research
(University of Missouri--Columbia, 2008)
of video, AVEDs provide a unique perspective not offered by other methods and facilitate research into animal behavior, foraging tactics, bioenergetics, wildlife damage issues, and inter- and intra-specific interactions. From 2006 to 2008, I assisted...
Habitat selection and movements of diploid and triploid grass carp in a large reservoir
(University of Missouri--Columbia, 2020)
. Attempts to capture fish with trammel nets using the Judas method proved difficult with only 1.9 fish caught/netting attempt versus 1.2 caught/netting attempt when selecting areas with suitable Grass Carp habitat for harvest. Fish were often observed near...
Impacts of suspended and deposited sediment on benthic invertebrates and fishes in a Missouri Ozark stream
(University of Missouri--Columbia, 2006)
Sediment is suspected in the decline of sensitive-aquatic organisms in the Osage River basin of Missouri. In this study, I monitored sediment dynamics and evaluated corresponding linkages with benthic invertebrate and fish ...
Spatiotemporal variation in Lake Sturgeon movement and habitat selection in Missouri river tributaries : implications for the management and recovery of populations at range margins
(University of Missouri--Columbia, 2021)
stocked at downstream sites from rkm 10 to 50. Overwinter survival rates were estimated from 40-55 % and were not significantly different among stocking sites. Age-0 Lake Sturgeon selected shallower depths than adults or subadults in both rivers...
Development and validation of standardized sampling protocols for assessing freshwater mussel populations in Missouri
(University of Missouri--Columbia, 2017)
Freshwater mussels are among the most threatened aquatic fauna in North America. Given the need for continued monitoring of threatened mussel species, an evaluation of the effectiveness of metrics from visually-based ...
Ecology of mid-continent migratory shorebirds, performance of tracking devices, and modelling animal social structure and demography
(University of Missouri--Columbia, 2022)
Migratory birds are threatened by landscape and climate change, and shorebirds are particularly imperiled. Shorebirds undertake some of the most impressive migrations in the world, but in every season, there are threats ...
