The Atlantic horse mackerel, also known as the European horse mackerel or common scad, is a species of jack mackerel in the family Carangidae, the jacks, pompanos and trevallies. It is found in the eastern Atlantic Ocean off Europe and Africa and into the south-eastern Indian Ocean. It is an important species in commercial fisheries and is listed as a Vulnerable species on The IUCN Red List of Threatened Species.
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.
Calanidae is the largest taxonomic family of calanoid copepods. It includes the genus Calanus, which may be the most abundant metazoan genus on Earth.
Acartiidae is a family of calanoid copepods distinguishable by the rostral margin not being extended. They are epipelagic, planktonic animals, not being found below a depth of 500 metres (1,600 ft). There are over 100 described species distributed throughout the world's oceans, mainly in temperate areas.
Acartia is a genus of marine calanoid copepods. They are epipelagic, estuarine, zooplanktonic found throughout the oceans of the world, primarily in temperate regions.
Acartia clausi is a species of marine copepod belonging to the family Acartiidae. This species was previously thought to have a worldwide distribution but recent research has restricted its range to coastal regions of the north-eastern Atlantic Ocean as far north as Iceland, the Mediterranean Sea and the Black Sea, with specimens from other regions assigned to different species.
Acartia teclae is a species of copepod belonging to the family Acartiidae. This species was discovered when specimens previously identified as Acartia clausi were examined and found to belong to a separate species. This species appears to have a similar range to, and occupies similar brackish estuarine habitats as, Acartia lefevreae but differs in the absence of spines on the dorsal part of the posterior body segment (metasome).
Acartia omorii is a species of marine copepod belonging to the family Acartiidae. This species was discovered when specimens previously identified as Acartia clausi were examined and found to belong to a separate species. This species is found around the coast of Japan. It is similar to A. clausi but lacks the prominent spines on the dorsal part of the posterior body segment (metasome).
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.
Acartia ensifera is a species of marine copepod belonging to the family Acartiidae. This is a slender copepod, around 0.8–0.9 mm (0.031–0.035 in) in length, with distinctively long caudal rami. It is found around the coasts of New Zealand.
Acartia simplex is a species of marine copepod belonging to the family Acartiidae. This species, just under 1 mm in length, is rather similar to Acartia ensifera but can be distinguished by the presence of spines on the dorsal part of the posterior body segment (metasome). Like A. ensifera, it is found around the coasts of New Zealand, mainly in estuarine habitats.
Acartia jilletti is a species of marine copepod belonging to the family Acartiidae. This species has a total length of up to 1 mm. It is very similar to Acartia ensifera but the female can be distinguished by the shorter caudal rami and the male by the relative length of spines on the fifth pair of legs. This species has been recorded from scattered locations around the coast of New Zealand.
Acartia tranteri is a species of marine copepod belonging to the family Acartiidae. This Australian species is related to the New Zealand species A. ensifera, A. jilletti and A. simplex but can be distinguished by the lack of any ventral prominence posterior to the genital opening in the female and the presence of posterior spines on the metasome of the male. It is found off the southern coast of Australia.
Cyclops bicuspidatus is a planktonic species of copepod found throughout the world, except Australia, and characteristic of the Great Lakes of North America. It is a deep water species found throughout the year with peak abundance occurring in May or June. Males grow up to 0.8–1.0 millimetre (0.031–0.039 in) long, while females are larger at 0.9–1.6 mm (0.035–0.063 in).
Ellobiopsis is a genus of unicellular, ectoparasitic eukaryotes causing disease in crustaceans. This genus is widespread and has been found infecting copepods from both marine and freshwater ecosystems. parasitism has been seen to interfere with fertility in both sexes of copepods.
Acartia tonsa is a species of marine copepod in the family Acartiidae.
Janet Mary Grieve, also known as Janet Bradford-Grieve and Janet Bradford, is a New Zealand biological oceanographer, born in 1940. She is researcher emerita at the National Institute of Water and Atmospheric Research in Wellington. She has researched extensively on marine taxonomy and biological productivity. She was president of both the New Zealand Association of Scientists (1998–2000) and the World Association of Copepodologists (2008–11).
Aetideidae is a family of copepods belonging to the order Calanoida.
Ann Bucklin is a professor at the University of Connecticut known for her work using molecular tools to study zooplankton. Bucklin was elected a fellow of the American Association for the Advancement of Science in 1995.
