Historic speciation and recent colonization of Eurasian monkey gobies (Neogobius fluviatilis and N.pallasi) revealed by DNA sequences, microsatellites, and morphology
نویسندگان
چکیده
Species introductions and movements world-wide provide valuable, large-scale ‘natural’ experiments to test fundamental hypotheses underlying ecological and evolutionary theory and may provide insights into the broad morphological, genetic, ecological or life history characteristics associated with their success and persistence (Sax et al., 2007; Blackburn, 2008; Great Lakes Genetics Laboratory, Lake Erie Center and Department of Environmental Sciences, University of Toledo, 6200 Bayshore Rd., Toledo, OH, 43616, USA

What's in a name? Taxonomy and nomenclature of invasive gobies in the Great Lakes and beyond
Index words: Gobiidae Invasive species Neogobius Proterorhinus Round Goby Tubenose Goby The species identities, scientific names, and relationships of Eurasian gobies that invaded the Laurentian Great Lakes – and other species that are predicted to invade in the future – are evaluated here using recently resolved DNA characters. The Round Goby and the Freshwater Tubenose Goby entered the Great ...
متن کاملEscape from the Ponto-Caspian: evolution and biogeography of an endemic goby species flock (Benthophilinae: Gobiidae: Teleostei).
Endemic Ponto-Caspian gobies include a flock of 24 "neogobiin" species (containing the nominal genera and subgenera Apollonia, Babka, Neogobius, Mesogobius, Ponticola, and Proterorhinus; Teleostei: Gobiidae), of which a large proportion (5 species; 21%) recently escaped to invade other freshwater Eurasian systems and the North American Great Lakes. We provide its first comprehensive phylogeneti...
متن کاملPostglacial colonization shows evidence for sympatric population splitting of Eurasian perch (Perca fluviatilis L) in Lake Constance.
Previous microsatellite analysis showed that two subpopulations of perch (Perca fluviatilis L) exist in Lake Constance. This raises questions of whether (i). Lake Constance was colonized by two populations that diverged in allopatry, or (ii). the two subpopulations diverged in sympatry. Sequence analysis of a 365 bp mtDNA fragment (5'-end of the D-loop) of perch from Lake Constance and adjacent...
متن کاملThe influence of environmental parameters on the abundance of monkey goby, Neogobius pallasi (Berg, 1916), in Kaboodval and Shirabad Streams, Golestan Province, Iran
The aim of this study was to determine the influence of environmental parameters onthe abundance of monkey goby Neogobius pallasi. A total of 526 and 163 individuals ofmonkey goby specimens were caught by electro-shocker in the Kaboodval and Shirabad Streams, respectively. The ranges of total length of the specimens in Kaboodval and Shirabad Streams were respectively 22-137.55 mm and 32.64-137....
متن کاملImpacts of the Eurasian round goby (Neogobius melanostomus) on benthic communities in the upper St. Lawrence River
An invasive benthivorous fish, the Eurasian round goby (Neogobius melanostomus) is abundant throughout the lower Great Lakes – St. Lawrence River system. We examined the round goby’s potential to alter benthic communities on cobble substrates in the upper St. Lawrence River. During the summers of 2008 and 2009, macroinvertebrates and benthic algae were sampled across sites with varying goby den...
