DETERMINATION OF STANDARD AND FIELD METABOLIC RATES IN TWO GREAT LAKES INVADING FISH SPECIES: ROUND GOBY (NEOGOBIUS MELANOSTOMUS) AND TUBENOSE GOBY (PROTERORHINUS SEMILUNARIS)
The dawn chorus is a bout of increased song output performed by birds prior to sunrise during the breeding season. Although nearly ubiquitous among avian species, the dawn chorus is poorly understood compared to daytime song. Little is known about how extrinsic variables influence dawn chorus …

Auditory development and multi-sensory integration in the round goby, Neogobius melanostomus
… auditory structure and function in the round goby (Neogobius melanostomus) to ascertain how developmental changes may influence hearing ability. In the second chapter of this dissertation, I investigate how the morphology of auditory and mechanosensory systems can be used to explain a fish's …

Watershed-scale patterns of seaward migration in Lentipes concolor, a Hawaiian stream goby
The native stream fishes of the Hawaiian Islands are uniquely adapted to colonize and thrive in lotic habitats in this extremely isolated archipelago. Chapter 1 of this dissertation introduces the five native fishes of Hawaii's streams and describes the variety of lotic habitats they occupy. All …

Characterizing Patterns Of Round Goby (Neogobius Melanostomus) Distribution Using Morphometrics, Occupancy Modeling, And Population Genetics
… mechanisms of dispersal, establishment of round goby, Neogobius melanostomus, in the Laurentian Great Lakes has generally benefitted from continuous connections among the lakes and accessible shorelines. This dissertation (1) examined the effects of distance in affecting round goby invasion and …

Range expansion in the invasive Round goby (Neogobius melanostomus): behavioural and gene transcriptional components of a successful invader
… novel environments. My study species, the round goby (Neogobius melanostomus), is an invasive fish continuously expanding its range in the Laurentian Great Lakes and its tributaries. This thesis aims to examine: 1) the behavioural repertoire of the round goby 2) differential gene transcription …

Effects of salinity stress, ammonia exposure and feeding on excretory nitrogen metabolism in the marble goby, oxyeleotris marmorata
… freshwater or seawater or feeding on the marble goby, Oxyeleotris marmorata. O. marmorata exhibited hyperosmotic hyperionic regulation in freshwater, but undergo hypoosmotic hypoionic regulation during seawater exposure. Short-term seawater exposure resulted in cell volume regulation partially …

Spatiotemporal trends and relationships in the abundance, growth, and condition of common nearshore fishes of southwest Lake Michigan
… represents a valuable sport fishery; the round goby, an invasive omnivore; and the alewife, an invasive planktivore. The objective of this research was to explore spatiotemporal patterns in the abundance of fishes in the nearshore area of the Illinois waters of Lake Michigan as well as to assess …

Interpreting Predator – Prey Interactions in Cayuga Lake Fishes Using Fatty Acid Signature Analysis
… lake; alewife (Alosa pseudoharengus) and round goby (Neogobius melanostomus). The main objectives of the study were to assess FAS dissimilarity between prey species and then compare each prey FAS to lake trout FAS. Fish were collected in 2014 and 2015 using seine nets (alewife, n = 255 and round …

Selected elements in Lake Michigan round goby (Neogobius melanostomus) reproductive physiology: spawning effort and determination of reproductive status of females and sperm competition in two reproductively distinct male morphs
The round goby (Neogobius melanostomus) is a species within a large, tolerant, prolific family of fishes, Gobiidae, and has successfully invaded the Laurentian Great Lakes over the past two decades. Among the many reasons for their success are physiological factors that allow round goby to rapidly …

Application of ANOVA for the analysis of temporal and spatial differences in the length of pelagic goby preyed on by Cape fur seals in the coasts of Namibia
… ANOVA was used to uncover the differences in goby length preyed on by three different colonies of fur seals at the Namibian coast. Moreover, ANOVA was used to investigate temporal differences in lengths of goby preyed on by fur seals in each location of the seal colonies. Results of the …

Diet and trophic relationships of fishes from the nearshore of the Bay of Quinte and Kingston Basin, Lake Ontario
… 2, diet and trophic position of the Round Goby (Neogobius melanostomus) varied seasonally and spatially between these two habitats. Stable isotopes indicated that stomach contents over-estimated the contribution of mollusc-prey to the diet of Round Goby and under-estimated the contribution …

FATTY ACID COMPOSITION OF BLACK SEA AND FRESHWATER FISH SPECIES / МАСТНОКИСЕЛИНЕН СЪСТАВ НА ЧЕРНОМОРСКИ И СЛАДКОВОДНИ РИБИ
… acid composition of eleven Black Sea (sprat, goby, shad, horse mackerel, red mullet, turbot, bluefish, anchovy, garfish, grey mullet and bonito) and four freshwater (carp, bighead carp, catfish and trout) commercially important fish species were determined. Seasonal changes of lipid content …

Diet Analysis of Burbot from Eastern Lake Michigan: 1999-2012
… ~15% in 2012. During the same time span, round goby (<em>Neogobius melanostomus</em>) contribution to burbot diet increased from ~0% before 2006 to greater than 60% in 2012, implying nearly a complete diet shift of burbot in just six years. The diet shift suggests a change in feeding behavior …

NAKED GOBIES (GOBIOSOMA BOSC) AS INDICATORS OF OYSTER REEF RESTORATION SUCCESS
… loose oyster shell, and ambient sediment. Naked goby abundance, length, dry weight, and biomass increased with the availability of oyster substrate and were positively correlated with the abundance of other resident macrofauna. Individual dry weight and biomass were greater on reefs with a high …

Aspects of Bowfin and Northern Sunfish Biology and Ecology
… invasive species have increased, such as round goby (Neogobius melanostomus; +200% CPUE). Analysis of similarities (ANOSIM) revealed a significant difference in the LTWC fish community between years (R = 0.806, P = 0.001), and non-metric multidimensional scaling (nMDS) showed a strong separation …
