Bythotrephes is a dominant predator on herbivorous zooplankton, perhaps even accounting for … Spiny water flea (Bythotrephes longimanus) are a microscopic freshwater zooplankton that invade lakes and can take over the bottom of the food chain, disturbing the ecology of the lake and presenting a serious potential threat to Minnesota lakes.They can decimate populations of Daphnia and other native zooplankton resulting in a decreased food source for native fish and … Invasive Species - (Bythotrephes longimanus) Spiny waterfleas are zooplankton (tiny animals) that feed on other zooplankton, decreasing the food supply for native fish. It is not an insect as its name might sound, but is actually a cladoceran, which is a type of crustacean. 1 computer file (PDF); v, 71 pages.In recent decades, average summer surface temperatures in Lake Superior have increased and the invasive predatory zooplankton, Bythotrephes longimanus, became established.

Description. The species has since expanded its range to . By 1988, the spiny water flea Bythotrephes longimanus was introduced to Lake Michigan and has been changing the ecosystem ever since. Its average length is only about one centimeter, but its long tail spine (70% of animal's total length) makes it easily distinguishable from other invertebrates and zooplankton. This predatory cladoceran zooplanktor, commonly known as the spiny waterflea (Bythotrephes longimanus; formerly identified as Bythotrephes cederstroemi), is a crustacean, a relative of crayfish and shrimp.A native of the Ponto-Caspian region of Eastern Europe and Western Asia, Bythotrephes … Bythotrephes longimanus. 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. Major: Integrated Biosciences. Spiny Water Flea (Bythotrephes longimanus) Bythotrephes longimanus, cederstroemi, spiny water flea (SWF), is a cladoceran (Crustacea) zooplankton, native to the Palearctic (Eurasia) region (Berg & Garton, 1994). Invasive Listing Sources. species that flourish in the water. 2126 Variation in the response of crustacean zooplankton species richness and composition to the invasive predator Bythotrephes longimanus Angela L. Strecker, Shelley E. Arnott, Norman D. Yan, and Robert Girard Abstract: The predacious invertebrate Bythotrephes longimanus has now invaded >90 freshwater lakes in North Amer- ica. Native to Eurasia, B. longimanus was first documented in North America in the Laurentian Great Lakes in the early 1980s. Bythotrephes longimanus What are spiny waterfleas? Categories. Bythotrephes appearance is similar to Cercopagis pengoi, another Great Lakes invader, … This organism is an aquatic macroinvertebrate predator that can alter zooplankton communities (Drake, Drury, Lodge, Blukacz, & Bythotrephes-in- The spiny water flea (SWF) is a free swimming, cladoceran zooplankton with a unique body structure. 130 lakes on the continent, signaling its capacity to overcome the invasive cladoceran Bythotrephes longimanus are of emerging concern in North America and Western Europe. Johnson. Ecosystems 11:490–503. Background | Biology & Impacts | New York Distribution Map. We evaluated the antipredator behaviour of Daphnia mendotae to the invasive invertebrate predator, Bythotrephes longimanus, and the consequent effect of the predator on prey growth rate (referred to as a non‐lethal effect of the predator).. 2. 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 … The Spiny Waterflea (Bythotrephes longimanus) is crustaceous zooplankton of the suborder Cladocera.It is native to freshwater lakes in northern Europe and Asia.

Advisors: Thomas Hrabik, Donn Branstrator. 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).
