Pumpkinseed Lepomis gibbosus (Linnaeus, 1758) (Centrarchidae) and associated parasites introduced to Norway
The North American freshwater sunfish, Lepomis gibbosus (Centrarchidae), was found in a pond outside Oslo, Norway in October 2005. The large number of fish (>100) in the pond suggests successful reproduction. Two monogenean parasites, nonnative to Norway, were found on the gill filaments of the fish. The origin of the fish and associated parasites is not known.
متن کاملContemporary and historical evolutionary processes interact to shape patterns of within-lake phenotypic divergences in polyphenic pumpkinseed sunfish, Lepomis gibbosus
Historical and contemporary evolutionary processes can both contribute to patterns of phenotypic variation among populations of a species. Recent studies are revealing how interactions between historical and contemporary processes better explain observed patterns of phenotypic divergence than either process alone. Here, we investigate the roles of evolutionary history and adaptation to current ...
متن کاملRestoration of visual function following optic nerve regeneration in bluegill (Lepomis macrochirus) x pumpkinseed (Lepomis gibbosus) hybrid sunfish.
Simple (dorsal light reflex) and complex (predator-prey interactions) visually mediated behaviors were used concurrently with morphological examination to assess restoration of visual function following optic nerve crush in bluegill (Lepomis macrochirus) x pumpkinseed (Lepomis gibbosus) hybrid sunfish. Regenerating optic nerve axons projected into the stratum opticum-stratum fibrosum et griseum...
متن کاملInterspecific Aggressive Behaviour of Invasive Pumpkinseed Lepomis gibbosus in Iberian Fresh Waters
Pumpkinseed Lepomis gibbosus (L.) are successful invaders in Europe, where this species exerts multiple ecological effects, mainly through trophic interactions. Behavioural interference represents a potential impact for native fauna and this is of particular conservation concern in the Iberian Peninsula because of the highly valuable endemic fauna inhabiting streams of this region. However, agg...
متن کاملMotor correlates of learning behaviour: feeding on novel prey by pumpkinseed sunfish (Lepomis gibbosus).
The functional basis of learning in prey capture was investigated in the pumpkinseed sunfish (Lepomis gibbosus). Feeding performance of sunfishes was assessed when the fish were first fed a novel, elusive prey (guppies) and compared with their performance after several weeks of experience with capturing guppies. During these feedings electromyographic recordings were made to document the patter...
