Epischura lacustris is a species of copepod in the family Temoridae.
The North American distribution of Epischura lacustris spans from the northeastern coastal United States, west to Minnesota, south to central Illinois and is currently found in all 5 of the Great Lakes as well as many other smaller waterbodies throughout its range. [1] [2] [3]
E. lacustris can be visually separated from all of the other calanoids found in the Great Lakes by looking at their caudal setae and at the urosome portion of their body. E. lacustris have three stout, well-developed setae present on each of the caudal rami, where as other calanoids will have four or more thin setae. Mature specimens have noticeably bent and crooked urosomes. [4]
The white bass, silver bass, or sand bass is a freshwater fish of the temperate bass family Moronidae. commonly around 12-15 inches long. The species' main color is silver-white to pale green. Its back is dark, with white sides and belly, and with narrow dark stripes running lengthwise on its sides. It has large, rough scales and two dorsal fins. They are widely distributed across North America, inhabiting large reservoirs and rivers. When mating in the spring, they are more often found in shallow rivers, creeks, and streams. They have been introduced in some places as sport fish and also to predate on nuisance fish, such as gizzard shad. It is the state fish of Oklahoma.
Copepods are a group of small crustaceans found in nearly every freshwater and saltwater habitat. Some species are planktonic, some are benthic, a number of species have parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, and puddles, damp moss, or water-filled recesses (phytotelmata) of plants such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as biodiversity indicators.
Calanoida is an order of copepods, a group of arthropods commonly found as zooplankton. The order includes around 46 families with about 1800 species of both marine and freshwater copepods between them.
Iris lacustris, the dwarf lake iris, is a plant species in the genus Iris, subgenus Limniris and in the section Lophiris. It is a rhizomatous, beardless perennial plant, native to the Great Lakes region of eastern North America. It has lavender blue or violet-blue flowers, a very short stem and long fan-like green leaves. It is cultivated as an ornamental plant in temperate regions. It is closely related to Iris cristata.
Diel vertical migration (DVM), also known as diurnal vertical migration, is a pattern of movement used by some organisms, such as copepods, living in the ocean and in lakes. The word diel comes from the Latin dies day, and means a 24-hour period. The migration occurs when organisms move up to the uppermost layer of the sea at night and return to the bottom of the daylight zone of the oceans or to the dense, bottom layer of lakes during the day. It is important to the functioning of deep-sea food webs and the biologically driven sequestration of carbon.
Mysis is a genus of mysid crustaceans in the family Mysidae, distributed mainly in the coastal zone of the Arctic and high boreal seas. Several species also inhabit northern freshwater lakes and the brackish Caspian Sea. Fifteen species are recognized. Body lengths range from 1 to 3 centimetres.
Epischurella baikalensis is a species of copepod in family Temoridae. It is endemic to Lake Baikal, being the dominant zooplankton species there: 80%–90% of total biomass. It measures 1.5–2 mm (0.06–0.08 in).
Hemiboeckella powellensis, is a zooplankton copepod of which only four of its kind have ever been observed. "Hemiboeckella" refers to this genus being a subvariant of Boeckella, whilst “powellensis” refers to Lake Powell in Western Australia, the region it is endemic to. Its existence was initially recorded in May and June of 1977, and has not been observed since.
Monstrilloida is an order of copepods with a cosmopolitan distribution in the world's oceans. The order contains a single family, Monstrillidae. The name of the first ever described genus Monstrilla is derived from latin, meaning "tiny monster", because the lack of usual diagnostic features of copepods puzzled early taxonomists.
The San Francisco Estuary together with the Sacramento–San Joaquin River Delta represents a highly altered ecosystem. The region has been heavily re-engineered to accommodate the needs of water delivery, shipping, agriculture, and most recently, suburban development. These needs have wrought direct changes in the movement of water and the nature of the landscape, and indirect changes from the introduction of non-native species. New species have altered the architecture of the food web as surely as levees have altered the landscape of islands and channels that form the complex system known as the Delta.
Acartia hudsonica is a species of marine copepod belonging to the family Acartiidae. Acartia hudsonica is a coastal, cold water species that can be found along the northwest Atlantic coast.
Branchinecta gigas is a species of fairy shrimp that lives in western Canada and the United States. It is the largest species of fairy shrimp, growing up to 86 mm (3.4 in) long. It is known commonly as the giant fairy shrimp.
Platycopiidae is a family of copepods. Until the description of Nanocopia in 1988, it contained the single genus Platycopia. It now contains four genera, three of which are monotypic; the exception is Platycopia, with 8 species.
Leptodiaptomus ashlandi is a calanoid copepod zooplankton native to the Laurentian Great Lakes and their basin.
Leptodiaptomus sicilis is a calanoid copepod native to the Laurentian Great Lakes and its basin.
Leptodiaptomus ashlandi is a calanoid copepod zooplankton.
Crystal Lake is one of at least 22 lakes of that name in the state of Wisconsin. It has a surface area of about 93 acres, and is located just south of Big Muskellunge Lake, in Vilas County in the Northern Highland region of Wisconsin. The nearest community is Sayner, about 5 miles to the east. Visitors have access to the lake from a public boat landing, public beaches and the Northern Highland-American Legion State Forest. Fish include panfish, largemouth bass, and trout.
Calanus propinquus is a copepod found in Antarctica, and the surrounding waters.
Neocalanus plumchrus is a large copepod found in the Pacific and Arctic Oceans. It was described in 1921 by Marukawa. N. flemingeri used to be placed in this species, likely as a form, until it was split in 1988 by Charles B. Miller.
Neocalanus cristatus is a species of copepod found primarily in the northern Pacific.
