NAKED GOBIES (GOBIOSOMA BOSC) AS INDICATORS OF OYSTER REEF RESTORATION SUCCESS
Naked gobies (</italic>Gobiosoma bosc</italic>) are the most abundant resident fish on oyster reefs in the Chesapeake Bay and serve as a critical trophic link between the benthic and pelagic communities. Their response to oyster restoration may therefore be a useful indicator of ecosystem …

STOMACH CONTENT ANALYSIS OF BOTULISM-AFFECTED BIRDS IN LAKE MICHIGAN
… season to use as BoNT/E-free references. Round gobies were found in 86% of the BoNT/E-positive birds, 76% of the BoNT/E-negative birds, and 94% of the BoNT/E-free cormorants examined in this study. The grand mean total length of gobies consumed by bird species ranged from 70.82 ± 3.42 mm in …

Friends in Low Places: Responses of a Benthic Stream Fish to Intra-Guild Alarm Cues
… and mosquitofish; alarm cues from Bumblebee Gobies (Brachygobius doriae) served as a negative (allopatric) control. We also tested the response of sympatric and allopatric darters to the damage-released alarm cues of Oklahoma Salamander. Darters exhibited a fright response to conspecific and …

Range expansion in the invasive Round goby (Neogobius melanostomus): behavioural and gene transcriptional components of a successful invader
… goby 2) differential gene transcription for gobies “natural” and environmental captive “treatment” using brain candidate genes associated with behavioural traits specific to aggression, boldness, stress response, learning, and activity; and 3) how behaviour and gene transcription vary between …

Auditory development and multi-sensory integration in the round goby, Neogobius melanostomus
… the physiological response of the round gobies to conspecific and heterospecific vocalizations. Responding to the vocalizations of a conspecific can help an individual locate food, shelter and mates. The results of this study indicate that on a physiological level, round gobies are able …

Soft sediment ecology of Lough Hyne Marine Reserve - spatial and temporal patterns
… infauna comprising decapods crabs and Fries’ gobies, was estimated by identifying and counting their distinctive burrow structures. While above the summer thermocline depth, burrow abundance increased in a linear fashion, below the thermocline depth a slight reduction of burrow abundance …

Dedicated dads: a study on the nesting behaviour of Spondyliosoma emarginatum (Telostei: Sparidae)
… and chasing away other fish species (sand gobies, Roman, and hottentot) and neighbouring male steentjies. Energy intensive behaviours such as clearing the nest and fanning the eggs remained constant irrespective of egg presence. In addition, males do not feed when guarding eggs, which …

Spatiotemporal trends and relationships in the abundance, growth, and condition of common nearshore fishes of southwest Lake Michigan
… models for round goby otoliths. Live round gobies were measured then marked with oxytetracycline to create a fluorescent ring on their otoliths and given an individual tag for later identification. After spending three months in the lab, fish were culled and otoliths were removed, viewed …

The bioaccumulation of persistent contaminants by zebra mussels and their effects on state-endangered common terns
… of zebra mussels which are consumed by round gobies (Neogobius melanostromus) and ultimately littoral fish (e.g. small-mouthed bass, Micropterus dolomieui) or terns. Because common terns breed in near-shore sites where concentrations of zebra mussels are found, as well as forage in more …

Spatial models of Hawaiian streams and Hawaiian stream fish habital
A series of spatially based models of Hawaiian streams and stream fish habitats were developed to aid in the conservation of native fishes. The spatial models focused on the quantification of habitat for native fishes at three levels within a spatial hierarchy. First, at the reach level, the models …
