Assessing the effects of anticoagulant rodenticides on non-target fish species
(University of Missouri--Columbia, 2018)
voiced by the public. To determine AR effects on coral reef fish found in Hawaii, U.S. Geological Survey was asked to address their sensitivity as a prerequisite of another DPN aerial broadcast over Lehua Island. In December 2016, we presented our...
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 ...
The effects of metal contamination on larval white sturgeon in the upper Columbia River
(University of Missouri--Columbia, 2018)
Sturgeon populations are imperiled worldwide. Declines are attributed to many factors including habitat degradation and alteration, overexploitation, and contamination. In North America, white sturgeon (Acipenser transmontanus) ...
Effects of riparian buffer width on stream salamander populations in the southern Appalachian Mountains
(University of Missouri--Columbia, 2008)
Salamanders in the Appalachian region have been extensively studied, but the majority of research assessing the impacts of logging has focused on terrestrial species that are not dependent on stream habitats for egg ...
Ecological genomics of divergence, admixture, and fitness in the smallmouth bass (Micropterus dolomieu)
(University of Missouri--Columbia, 2021)
The Smallmouth Bass (Micropterus dolomieu) is one of the most highly targeted sport fishes in the world. Anglers vie for the opportunity to catch Smallmouth Bass recreationally and competitively, spending billions of dollars ...
The evolutionary significance of developmental plasticity in the communication system of Neoconocephalus triops (Orthoptera: tettigoniidae)
(University of Missouri--Columbia, 2008)
The katydid Neoconocephalus triops is a tropical species that extended its distribution range to North America. In North America, males display developmental plasticity in mating calls between reproductive generations: the ...
Amphibian metamorphosis and juvenile terrestrial performance following chronic cadmium exposure in the aquatic environment
(University of Missouri--Columbia, 2005)
[mu]g Cd/L. The experimental endpoints were survival, mass and age at metamorphosis, and whole body Cd content. Both species had a decrease in survival and increase in larval period and Cd content with increasing aqueous Cd concentration. However...
Multi-scale investigations of gray treefrong movements: patterns of migration, dispersal, and gene flow
(University of Missouri--Columbia, 2005)
The movement of individuals within and among populations has been recognized as an important determinant of the persistence of species. Fragmentation of terrestrial landscapes has exacerbated the need to understand the ...
Effects of prescribed fire and timber harvest on terrestrial salamander abundance, behavior, and microhabitat use
(University of Missouri--Columbia, 2014)
The goal of my dissertation was to assess how terrestrial salamanders respond to two common forest management practices -- prescribed fire and timber harvest. Previous studies have reported that timber harvest adversely ...
Tales of an 'invisible' life stage : survival and physiology among terrestrial juvenile ambystomatid salamanders
(University of Missouri--Columbia, 2019)
The vital rates (e.g., survival, growth, and reproduction) of distinct life stages within a species are known to influence the growth and persistence of populations. As such, studies describing stage-specific vital rates, ...
A monograph of Lupinus for Argentina
(University of Missouri--Columbia, 1978)
The species of Lupinus for Argentina are reviewed in a morphological and taxonomic study. For the country of Argentina and vicinity there were 85 species cited. Over 45 holotypes, numerous isotypes and several non-type ...
