Recruitment of the intertidal barnacle Semibalanus balanoides ; metamorphosis and survival from daily to seasonal timescales
The benthic habitat is the terminal destination for marine animals in terms of their reproductive lifecycle. Recruitment dynamics relating to seasonal changes in the benthic habitat may be the best source of information for predicting recruit abundance and for marine resources management. The …

Adult demography and larval processes in coastal benthic populations intertidal barnacles in Southern California and Baja California
… geographic distribution and dynamics of coastal benthic populations are shaped by physical biological interactions affecting larval dispersal and the demography of juvenile and adult individuals. This thesis focused on nearshore patterns of larval distribution and regional patterns in demography …

Biophysical coupling between turbulence, veliger behavior, and larval supply
The goals of this thesis were to quantify the behavior of gastropod larvae (mud snails Ryanassa obsoleta) in turbulence, and to investigate how that behavior affects larval supply in a turbulent coastal inlet. Gastropod larvae retract their velums and sink rapidly in strong turbulence. …

Mitochondrial genomics and Northwestern Atlantic population genetics of marine annelids
… goal of this thesis was to investigate marine benthic invertebrate phylogenetics and population genetics, focused on the phylum Annelida. Recent expansions of molecular methods and the increasing diversity of available markers have allowed more complex and fine-scale questions to be asked at a …

Analysis of the Benthic Macroinvertebrate Community Structure for Assessment of Water Quality of the Des Moines River
… was accomplished by sampling and analyzing the benthic macroinvertebrate community. Procedure. Artificial substrates at five stations collected macroinvertebrates. Community structure was analyzed using species diversity indices. Species diversity (D) and redundancy (R) values were used to …

Benthic Population Distributions in Red Rock Reservoir, Iowa Summer 1972
The problem. To determine the distribution of benthic invertebrates in Red Rock Reservoir and to relate this distribution to the physiochemical characteristics of the substrate and bottom meter of water along with water retention time after three years of impoundment. Procedure. Benthic samples …

Species Diversity of Benthic Macroinvertebrates in the Des Moines River, Iowa
… Moines River. Iowa by sampling and analyzing the benthic macroinvertebrate community. Procedure. Artificial substrates at four stations were used to collect benthic macroinvertebrates. Community structure was analyzed with species divorsity indices. Species diversity (D) and redundancy (R) values …
