A Lota lota Consumption: Trophic Dynamics of Nonnative Burbot in a Valuable Sport Fishery
Unintentional and illegal introductions of species disrupt food webs and threaten the success of managed sport fisheries. Although many populations of Burbot Lota lota are declining in the species’ native range, a nonnative population recently expanded into Flaming Gorge Reservoir (FGR), Wyoming–Utah, and threatens to disrupt predator–prey interactions within this popular sport fishery. To dete...
متن کاملPopulation genetic structure of North American burbot (Lota lota maculosa) across the Nearctic and at its contact zone with Eurasian burbot (Lota lota lota)
The burbot, Lota lota (Teleostei: Gadidae), has a holarctic distribution, with one subspecies (Lota lota lota) living in the lakes and rivers of the Palaearctic and northwestern North America and the other (Lota lota maculosa) living in the Nearctic (except the northwest). We analysed nine microsatellite loci and the mitochondrial DNA control region of 350 burbot sampled across North America to...
متن کاملRegulation of cardiac contractility in a cold stenothermal fish, the burbot Lota lota L.
In the present study, burbot (Lota lota L.) was used as a model to study the effects of acute temperature changes on cardiac contractility in a cold stenothermal fish. The burbot were captured in the breeding season (February) and were maintained for 4 weeks at 1-2 degrees C in the laboratory before the contractile properties of the heart were measured. Both isometric force and the pumping capa...
متن کاملGenetic admixture of burbot (Teleostei: Lota lota) in Lake Constance from two European glacial refugia.
The burbot, Lota lota, is the only freshwater species of the codfish family and has a Holarctic distribution. Pleistocene glaciations caused significant geographical differentiation in the past, but its life history characterized by winter spawning migrations over large distances is likely to homogenize populations by contemporary gene flow. We investigated the population genetic structure of 5...
متن کاملThe effect of temperature on embryonic and yolk-sac larval development in the burbot Lota lota.
The present study investigated the effect of various temperature regimes on embryonic and yolk-sac larval development of the burbot Lota lota. At constant temperature regimes a high percentage of ready-to-hatch embryos, hatched larvae and normally shaped larvae was observed at the lowest temperature (2° C), which significantly decreased with increasing temperatures (4 and 6° C). No larvae hatch...
