Revision of trends in copepod conservation in different habitats, worldwide

Diversity and distribution of free-living freshwater copepods of Mexico

Gulcamptus huronensis Reid, 1996 is a seldom-reported harpacticoid copepod known only from two female specimens , one collected from Lake Huron, Michigan, USA, the other from Nunatak Creek, Alaska, USA. Herein, we report a new distributional record for G. huronensis from the meiobenthos of Lake Superior, Michigan and Wisconsin, USA. A total of 12 s...

For 43 years the only copepod species known from the Florida Keys was Apocyclops panamensis (Marsh, 1913), collected from a slough on Sugarloaf Key (Yeatman 1963). Recent, adventitious collections from fresh- and brackish surfacewater habitats and artificial containers in the Florida Keys, mostly made during inspections for mosquito larvae, have ha...

The Asian cyclopoid copepod Mesocyclops pehpeiensis Hu, 1943 has been reported as an introduced species at several locations in the western hemisphere. In the United States, reports of this exotic species are restricted to localities in Louisiana, Mississippi, and Washington D.C. This report documents a new record of occurrence for M. pehpeiensis f...

The cyclopoid copepod Thermocyclops crassus, native to Eurasia and Africa, was detected at two sites in the western basin of Lake Erie in August 2014. T. crassus was subsequently detected in samples collected from two sites in western Lake Erie in August 2015 and four sites in August 2016. Densities of adult T. crassus remained relatively low but i...

Parastenocaris brevipes Kessler is redescribed and its presence in North America is established through comparison of specimens from the U.S.A., Finland, and Germany. Parastenocaris wilsoni Borutskii, Parastenocaris starretti Pennak, Parastenocaris biwae Miura, and Parastenocaris sp. 2 Strayer (Strayer, D.L. 1988. Stygologia, 4: 279–291.) are assig...

Copepods are one of the most successful groups of animals on Earth. Their high densities in the world's oceans make copepods one of the most abundant metazoan groups. The Laurentian Great Lakes, which contain another 20% of the world's unfrozen freshwater, are also dominated by copepods, as are other notable lakes such as Lake Tahoe in the United S...

Crustacean species from Brazil were evaluated to define their conservation status under the Categories and Criteria of the IUCN Red List of Threatened Species at the regional level. This study represents an effort of the Chico Mendes Institute for Biodiversity Conservation (ICMBio), the Brazilian agency for conservation of biodiversity, and the Bra...

1. With few exceptions, copepods dominate over other crustacean and non‐crustacean invertebrate groups in ground water. They have colonised a vast array of habitats in continental ground waters, where they are represented by over 1000 species in six orders: Platycopioida, Misophrioida, Calanoida, Cyclopoida, Harpacticoida, Gelyelloida. However, mem...

The presence of populations of the Afro-Asian cyclopoid copepod crustacean Mesocyclops thermocyclopoides Harada, 1931, in southeastern Mexico and in Central America is recorded. This species was recently redescribed in detail from Old World specimens. Because of the rarity of cosmopolitan forms in Mesocyclops, neotropical records of this species we...

A recent find of the groundwater-inhabiting copepod crustacean Diacyclops harryi extended the known range of this species far northwestward, to include northern Ohio and the drainage basin of the Laurentian Great Lakes. The species was previously collected in drainages of the Atlantic Slope from New York to North Carolina. Ostracodes tentatively id...

We redescribe Speocyclops yezoensis Ito on the basis of specimens from Japan and from Alaska and Tennessee, U.S.A. The combination of the segmentation of the swimming legs; the lack of dimorphism in the structure of the swimming legs, except for the modified terminal spine of the leg 3 endopodite in the males of some populations; the partly fused p...

Three species of harpacticoid copepods are newly reported from long- and short-hydroperiod groundwater and surface freshwater habitats in Everglades National Park, Florida, U.S.A. One is new to science and described herein; Nitokra evergladensis, new species, differs from congeners mainly in details of setation and spination of the endopodites of t...

The genus Murunducaris, previously represented by a single species (M. juneae) collected in a hillside flush marsh near Brasília, Brazil, is revised here. The description of M. juneae is emended. Three additional species are assigned to the genus, and its geographical distribution is considerably expanded. Murunducaris noodti n. sp., from the vicin...

Biological control, copepods, Mesocyclops aspericornis, Mesocyclops reidae, Cuba

Copepod (Crustacea) species diversity was remarkably low on Plummers Island, Maryland, and its immediate environs over a year-long sampling period in 1996 and 1997, compared to that previously and contemporaneously reported nearby within the Potomac River Basin; only two species were found on the Island and two others in the adjacent side channel o...

The four species of freshwater copepod crustaceans found in ballast water or sediments in ships and characterized as "nonindigenous" to the Laurentian Great Lakes region by Drake and Lodge (Can. J. Fish. Aquat. Sci. 64: 530-538 (2007)) are all widespread, North American natives. Drake and Lodge's use of these native species to estimate the size of...

We report new records of copepods of the genus Mesocyclops from Cuba. In the tropics, several species of Mesocyclops have shown promise as biological control agents for the larvae of disease-bearing mosquitoes. Mesocyclops aspericornis is considered pan-tropical, but has not previously been recorded here. Mesocyclops reidae, now found in a new loca...

The copepod crustacean fauna collected from subterranean habitats, including caves, wells, and the hyporheos of streams in and near the Interior Low Plateaus of the United States is dominated by Cyclopoida, with 39 species, followed by Harpacticoida with 9, and Calanoida with 2. Nearly all of the harpacticoid and calanoid species are widespread, pr...

Cyclopoid copepods have proved more effective for practical mosquito control than any other invertebrate predator of mosquito larvae. Their operational potential is enhanced by the fact that mass production is relatively easy and inexpensive. The exceptional potential of copepods for mosquito control was first realized about 25 years ago. Since the...

The planktonic copepod crustacean Arctodiaptomus dorsalis (Marsh) was found in ponds at two warmwater-fish hatcheries in Virginia in the summer of 2006. Because no permanent population is known to exist north of Florida in the eastern United States, the Virginia populations are considered to be introduced. These discoveries provided the impetus for...

In summary, the cyclopoid copepod fauna of Cuba includes species of Mesocyclops, which are all excellent candidates for the biological control of mosquito larvae. Because native species are already adapted to local environmental conditions, and also because of the convenience of avoiding the introduction of exotic fauna, it is normally a good pract...

Collections from small permanent or ephemeral surface waterbodies, some of them brackish, in the Florida Keys yielded 2 species of calanoid, 17 species of cyclopoid, and 11 species and subspecies of harpacticoid copepod crustaceans. Most of the species are either cosmopolitan or widely distributed in the Neotropics. Even so, these collections have...

We report the results of a survey of copepods in burrows of Parastacus defossus, near Lami, Porto Alegre, Rio Grande do Sul, Brazil, conducted during the rainy seasons of 2003 and 2004. Copepods were also collected from surface water in nearby ephemeral pools. Twelve species of copepods (6 cyclopoids and 6 harpacticoids) were found either consisten...

Copepod microcrustaceans were collected from wetlands in five county parks and one privately managed neighborhood park in the Piedmont region of Virginia. A total of 43 species was found, 9 to 19 copepod species in each park. First state records were established for 16 species: Acanthocyclops brevispinosus, A. exilis, A. parasensitivus, A. robustus...

A complete record of the range of most species of zooplankton within river systems is rare. The calanoid copepod Eurytemora affinis has a relatively detailed description of its range in fresh waters, mostly because of its recent invasion into freshwater. Within the Ohio River, E. affinis has been documented twice, but these reports are from only a...

We present an inventory of the free-living freshwater copepod crustaceans recorded from the state of Florida, U.S.A. The list is based on previously published information and on new data collected during recent research on surface- and groundwater-dwelling copepods in Everglades National Park, and a few collections in temporary and permanent surfac...

The distributional patterns and diversity of the diaptomid calanoid copepods were analysed to assess the faunistic affinity of North and South America with respect to Mexico and Central America. In the Neotropical region, the most speciose genera of Diaptomidae are Leptodiaptomus and Mastigodiaptomus. The former genus is a Nearctic form, and Mastig...

Ten species of the cyclopoid copepod genus Diacyclops were collected by Julian J. Lewis and his associates from caves, wells, and the hyporheic zone of streambeds in karst and non-karst terrain in southern Indiana, USA. These collections included six previously known species: D. crassicaudis brachycercus, D. jeanneli, D. navus, D. nearcticus, D. so...

A new species of ameirid harpacticoid copepod, Stygonitocrella sequoyahi, was collected in streambeds in Arkansas and Oklahoma, U.S.A., and is described herein . The new taxon shares with its congeners the I-seg­ mented endopodite of leg 4, but differs in having much longer caudal rami, as well as in the major armament of the swimming legs. Other s...

We present a complete, updated inventory of free-living copepod crustaceans from Everglades National Park and outside its northeastern border, and adjacent Big Cypress National Preserve, based on published information and on unpublished data collected during recent long-term research on surface- and groundwater-dwelling copepods. We provide detaile...

Members of a new genus and species of harpacticoid copepod crustacean appeared in samples from semi-terrestrial (moist arboreal mosses, wet soil) and aquatic (bromeliad tanks, Sphagnum moss, rock pools, stream) habitats in a remnant of the Atlantic Forest in south-eastern Brazil. The new taxon, for which we propose the name Pindamoraria boraceiae s...

The free-living continental copepod fauna of the Yucatan Peninsula has been studied for decades; recent intensive surveys suggest that its biodiversity is higher than formerly realized. An updated, revised checklist of the Yucatan copepods is provided herein. This new list includes 59 species, more a than 30% increase from the most recent previous...

Moraria hudsoni n. sp. is described from Trails End Bay in Lake Michigan and Prentiss Bay in Lake Huron, Michigan, USA.

A discussion on the conservation problems of continental copepods from several parts of the world is presented, based on the experience of local experts. The status of some copepod species of concern for the IUCN Red List is evaluated.

We report new national records of Thermocyclops decipiens and Mesocyclops pseudomeridianus and two apparently undescribed species of Diacyclops and Halicyclops from Panama. We provide a complete bibliography of all literature on Panamanian copepods, and a table of historic copepod collection sites is presented.

An adult female of the cyclopoid copepod crustacean Apocyclops dengizicus (Lepeshkin) was found in the leaf vase of a northern pitcher plant, Sarracenia purpurea Linnaeus, in a freshwater boggy area on the coastal plain of eastern Virginia, USA. This is the first confirmed record of A. dengizigus, an Old World species, in the Americas. Species of A...

Currently, less than 10% of the members of the World Association of Copepodologists are working actively on symbiotic copepods. This surprisingly small guild of workers is thought to result from a general lack of understanding of the importance of symbiotic copepods. Symbiotic copepods as a whole comprise more than one-third (4224/11956 or 35.33%)...

Studies of development time of marine and freshwater copepods have taken separate tracks. Most studies on marine copepods report development time of each individual development stage, whereas studies on freshwater copepods report only development time, from egg to nauplius and nauplius to adult. This bias allows comparison of total development time...

Three species of harpacticoid copepods are newly reported from long- and short-hydroperiod groundwater and surface freshwater habitats in Everglades National Park, Florida, U.S.A. One is new to science and described herein; Nitokra evergladensis, new species, differs from congeners mainly in details of setation and spination of the endopodites of t...

Free-living freshwater copepods can be distinguished from other small aquatic invertebrates by a variety of morphological characteristics. They have a cylindrical, segmented body with numerous segmented appendages on the head and thorax, and two setose caudal rami on the posterior end of the abdomen. They possess an exoskeleton, conspicuous first a...

1. The effect of an exotic, burrowing bivalve (Corbicula fluminea) on the benthic fauna of a sandy-bottomed stream was assessed by field and laboratory experiments. Corbicula differs from other freshwater, non-native bivalves in that it both filter- and pedal-feeds and thus has the potential to influence the streambed community in different ways. 2...

Water management practices in the Everglades have severely stressed the natural system, particularly by reducing the hydroperiods of much of the region. During the dry season of 1999, we investigated the influence of hydroperiod on the species composition and dormancy patterns of freshwater copepod communities in seasonal wetlands of Everglades Nat...

Copepods have invaded an astonishing variety of aquatic and humid continental environments and microhabitats. The historical process of discovery and investigation of copepods in ephemeral, acid and thermal waters, subterranean waters and sediments, phytotelmata, humid soils, leaf litter, human-modified and artificial habitats, and other situations...

During a severe drought period in the winter and spring of 1989, we made three collections of dried marsh soils from freshwater sloughs in Everglades National Park, Florida, at sites characterized by either long or intermediate annual periods of flooding (hydroperiod). After rehydrating the soils in aquaria, we documented the temporal patterns of c...

Two new species of harpacticoid copepods from Everglades National Park Florida, Elaphoidella marjolyae sp. nov. and Elaphoidella fluviusherbae sp. nov., are described. Whereas E. majoryae was collected from both surface waters and groundwater, E. fluviusherbae was found only in groundwater. The new species differ from congeners mainly in details of...

We redescribe Speocyclops yezoensis Ito on the basis of specimens from Japan and from Alaska and Tennessee, U.S.A. The combination of the segmentation of the swimming legs; the lack of dimorphism in the structure of the swimming legs, except for the modified terminal spine of the leg 3 endopodite in the males of some populations; the partly fused p...

Prehendocyclops, a new genus of Halicyclopinae, is described from cenotes of the Yucatan Peninsula, Mexico. Within the subfamily, the new genus resembles Halicyclops, Colpocyclops, and Smirnoviella in body shape as well as structure of the antennule and legs 1 to 5. In addition, Prehendocyclops shares with the latter two genera modifications in the...

Paracyclops canadensis (Willey) (Copepoda: Cyclopoida) is not common in collections and is considered rare. We sampled purple pitcher plants, Sarracenia purpurea L. (Sarraceniaceae) from ten geographically separated sites to determine how common P. canadensis is. Ninety specimens of Paracyclops canadensis were recovered from 660 leaves of the purpl...

This paper describes the process of expanding a successful dengue control program in 3 provinces in northern Vietnam into a national one and demonstrates the presence of a rich, low-cost resource that could have similar applicability to other countries in the region. The cornerstone of the preventive strategy is larval control of Aedes aegypti (L.)...

A review of published records and material of the cyclopoid copepod Mesocyclops edax (S. A. Forbes) established its presence in the drainage basins of the Colorado and Columbia Rivers in the western U.S.A., and verified published records from Cuba, Guatemala, and Mexico. Mesocyclops nicaraguensis Herbst is a junior synonym of M. edax. We provide su...

Most species were collected from the hyporheic zones of stream beds, except R. indiana which...

We sampled the hyporheic cyclopoid copepods of 14 unpolluted sites in the eastern United States to test whether community composition differed between glaciated and unglaciated sites. We found 31 species of cyclopoids in all, over half of which were new to science or only recently described. All of these newly discovered species were interstitial s...

Collections from Brazil, Puerto Rico, and the U.S.A. yielded new records of 3 species of Bryocyclops. Both sexes of Bryocyclops muscicola are described from a probably introduced population found in a plant nursery in Florida, U.S.A., and compared to material of B. muscicola from Java. This is the first record of the genus in North America. The kno...

Taxonomic analysis of the copepod specimens collected from 29 Cayman Island ponds revealed the presence of ten species including the nearly ubiquitous cyclopoid Apocyclopspanamensis. This species was widespread throughout the islands, being collected at 27 of the sampling sites. Another common calanoid, Mastigodiaptomus nesus, occurred at nine site...

Halicyclops cenoticola sp. nov. is described from cenotes of the Yucatan Peninsula, Mexico. The new species shares exclusively with H. caridophilus and H. tetracanthus the presence of 2 inner setae on the leg 5 exopod in the males. As far as is known, the new species is distinguished from all its congeners in having the dorsal caudal seta as long a...

In northern Vietnam, copepods of the genus Mesocyclops were used for biological control of Aedes aegypti, the principal vector of dengue viruses, by inoculation into wells, large cement tanks, ceramic jars, and other domestic containers that served as Ae. aegypti breeding sites. The use of Mesocyclops was complemented by community participation wit...

Tortanus (Boreotortanus), new subgenus, is established to accommodate the North Pacific/northwestern Atlantic species T. discaudatus and the taxonomy and ecology of the five subgenera in the genus Tortanus are discussed.

The female of Gulcamptus huronensis, new species, is described from Lake Huron and Alaska ; the...

In phytotelmata of Jamaican bromeliads the harpacticoid copepods Epactophanes richardi Mrzek, 1893, Phyllognathopus viguieri (Maupas, 1892) and Attheyella (Canthosella) mervini sp. n. occurred. The new species conforms to the diagnosis of the subgenus, despite the fact that the endopods of legs 2–4 have retained more setae than in the species known...

Four previously unknown hypogean species of cyclopoid copepods were collected in cenotes and wells of the Yucatan Peninsula, Mexico. Diacyclops chakan sp. n. and D. puuc sp. n. differ from their congeners in combining 3-segmented swimming legs, 11-segmented antennules, and legs 1-4 endopodite segment 2 all with 2 setae. Species of Diacyclops rarely...

The freshwater copepods are a group with very interesting ecological characteristics; their real importance in the continental aquatic ecosystems is unquestionable; however, there is scarce knowledge of them. These microcrustaceans are found mainly in tropical zones; in Mexico, a large quantity of continental bodies of water exist whose copepod fau...

Hesperodiaptomus californiensis, new species (Copepoda: Calanoida: Diaptomidae) was collected from vernal pools in Lassen County, northern California, U.S.A. It differs from its three most morphologically similar congeners, Hesperodiaptomus schefferi, Hesperodiaptomus victoriaensis and Hesperodiaptomus kiseri in having both leg 5 endopods of the ma...

1. We have previously shown that the impact of spates on stream invertebrates may differ among patches separated by distances of metres or less. Here we analyse the species‐specific flood responses of larval chironomids and adult and near mature copepods living in different patch types. Four patch types (with eight replicates of each) were compared...

Cyclopoid copepod crustaceans were collected in benthic and littoral samples from spatially limited mosquito-breeding habitats including a canal, small perennial and ephemeral ponds, sloughs, swales, rice fields, ditches, puddles, cemetery pits, and old tires in southern Louisiana, principally in greater New Orleans, and in Mississippi. The local f...

ABSTRACT Specimens of a new parastenocaridid copepod were collected from a murundu mound and nearby soil in the central Brazilian highlands. Principal diagnostic features of Murunducaris juneae, new genus, new species, include, in both sexes, the posterior insertion of the spiniform seta of leg 4 exopodite article 1, and, in the male, the fifth leg...

Diacyclops dimorphus, new species, was collected from clean sand sediments of the Blackwater River, State of Florida, USA. The new species differs from congeners in that the female has all rami of the swimming legs biarticulate, but the male has most rami biarticulate and the leg 4 exopodite triarticulate. Only two other species of Diacyclops show...

The copepod (Crustacea) fauna of the orders Harpacticoida and Cyclopoida was studied in the cerrado region of central Brazil.
