Parthenogenically produced animals have kink in middle of their spine and sexually produced animals lack the kink. In a laboratory experiment, Daphnia in the absence of Bythotrephes kairomones remained in the top, warmer regions of … Native to Eurasia, B. longimanus was first documented in North America in the Laurentian Great Lakes in the early 1980s. Many characteristics are hard to identify without magnification because they gather in gelatinous clumps (pictured right). 1. Gillis MK, Walsh MR. 2017. Bythotrephes longimanus Leydig, 1860 . Bythotrephes longimanus is an invasive zooplankton predator, negatively impacting zooplankton abundance and diversity in North American lakes.Previous studies have shown that Daphnia populations in lakes move to deeper waters during the day, in the presence of Bythotrephes, a visual predator occupying well-lit regions.However, Daphnia vertical position … In some cases, although indigenous prey do not go extinct, invasive predators displace them from their usual range or habitat; thus, the predatory cladoceran Bythotrephes longimanus causes some copepod taxa to escape to deeper and colder water layers in lake Michigan (Bourdeau et al., 2011).

Several invasive species of zooplankton in the United States, such as Bythotrephes cederstroemi (the spiny water flea) and Daphnia lumholtzi, have very long spines (East et al., 1999; Fig. The invasion of the nonindigenous zooplankter Bythotrephes longimanus in Lake Simcoe has the potential to impact overall ecosystem functioning, yet there is currently no information regarding the status and dynamics of its population.We used a combination of uni- and multivariate analyses to examine variation in Bythotrephes interannual and seasonal … 19.4). The spiny water flea is a microscopic animal that prefer deep clear lakes. Bythotrephes is a dominant predator on herbivorous zooplankton, perhaps even accounting for … Many of these nuisance plants and animals can be unknowingly carried on fishing gear, boating equipment, or in very small amounts of water in a watercraft. Invasive Species of Concern in Maryland; By 1988, the spiny water flea Bythotrephes longimanus was introduced to Lake Michigan and has been changing the ecosystem ever since. Advisors: Thomas Hrabik, Donn Branstrator. Data from: Rapid evolution mitigates the ecological consequences of an invasive species (Bythotrephes longimanus) in lakes in Wisconsin.

Both in their native range and throughout the regions in which they have been introduced, the spiny water flea prefers large, deep lakes whose benthic zones have relatively low summer temperatures.
