Environmental DNA (eDNA) is revolutionizing biodiversity monitoring, occupancy estimates, and real-time detections of invasive species. In the Great Lakes, the round goby (Neogobius melanostomus), an invasive benthic fish from the Black Sea, has spread to encompass all five lakes and many tributaries, outcompeting or consuming native species; however, estimates of round goby abundance are confo...

Largemouth (LMB: Micropterus salmoides) and Smallmouth Bass (SMB: Micropterus dolomieu) are important species in the recreational fisheries of the Laurentian Great Lakes. The invasion of the Round Goby (Neogobius melanostomus) into these lakes has changed several facets of black bass biology, but there is still much to learn about the relationship between these species. Previous dietary analyse...

The heyday of ‘Redneck’ cinema—the 1970s to early 1980s, saw the rise Redneck Rebel—a Southern or otherwise ‘hick’ anti-hero who rode around countryside like a modern-day cowboy vanquishing evil. His ‘horse’ was his car—a beefed up/souped up muscle car that often became star show and overshadowed himself. This article examines Rebel through lens one American TV series—The Dukes Hazzard. popular...

Index words: Amphipod Echinogammarus Facilitation Gammarus Predation Round goby In Lake Erie and Lake Ontario, the Ponto-Caspian amphipod Echinogammarus ischnus has replaced the native amphipod Gammarus fasciatus on rocky substrates colonized by dreissenid mussels, which provide interstitial refugia for small invertebrates. Based on the premise that an invader's vulnerability to predation is in...

in this study, a total of 146 specimen of fish species from garmrood river of amol, mazandaran province in the summer 2011 were caught by local fishermen which including ,10 sand goby (neogobius fluviatilis),4 round goby (neogobius melanostomus), 48 capoeta capoeta, 73 albernoides bipunctatus, 5 leuciscus cephalus, 7 cobitis taenia and 4 nemacheilus nemacheilus. the fishes were transported a li...

Phenotypic plasticity buffers organisms from environmental change and is hypothesized to aid the initial establishment of nonindigenous species in novel environments and postestablishment range expansion. The genetic mechanisms that underpin phenotypically plastic traits are generally poorly characterized; however, there is strong evidence that modulation of gene transcription is an important c...

The round goby (Neogobius melanostomus Pallas 1811) is a non-native species in the Gulf of Gdańsk. The aim of this article is to assess the absolute fecundity and attempt to describe the gonad development cycle of round goby specimens from the Gulf of Gdańsk. The stages of gonad development were classified according to the modified Nikolski (1963) scale for perciformes, which was adapted for th...

More broadly, however, we need to get the message to the ordinary taxpayer and to legislators of the importance of basic research and of stable, longterm funding for research that only governments can afford to support. I wonder if we could convince Fox News in the USA to have a ‘redneck scientist’ segment in which a ‘salt of the earth’ scientist explains to the Fox audience how basic research ...

A growing concern over endocrine disruption in aquatic species has prompted the development of molecular assays to monitor environmental impacts. This study describes the development of quantitative polymerase chain reaction (qPCR) assays to characterize the expression of two vitellogenin (Vtg) genes in the invasive round goby (Neogobius melanostomus). Fragments from the 18SrRNA (housekeeping g...
