Abstract:

The present paper aims to describe the spatial distribution of zooplankton copepods, their biomass and instantaneous secondary production, in Barra Bonita, a large eutrophic, polymitic reservoir (22° 29' S and 48° 34' W) on the Tietê River, of the Paraná basin. Sampling was carried out during two seasons: dry winter and rainy summer. Species composition, age structure and numerical density of each copepod species population were analyzed at 25 sampling stations. Secondary production was calculated for Copepoda, the dominant group in zooplankton communities, taking Calanoida and Cyclopoida separately. Copepoda represented the largest portion of the total zooplankton biomass, the dominant species being Notodiaptomus iheringi among the Calanoida and Mesocyclops ogunnus and Thermocyclops decipiens among the Cyclopoida. The production of Copepoda was higher during the rainy summer (23.61 mgDW.m-3.d-1 in January 1995) than during the dry winter season (14 mgDW.m-3.d-1 in August 1995), following the general pattern of abundance for the whole zooplankton community. Among the copepods, Cyclopoida production was higher than that of Calanoida, a pattern commonly observed for tropical lakes and reservoirs. Barra Bonita copepods are very productive, but there was a great degree of spatial heterogeneity, related to the physical and chemical conditions, particularly the level of nutrients and also to phytoplankton biomass.

Abstract:

The success of planktonic copepods in aquatic environments is dependent on efficient sensing of their three-dimensional surroundings. The detection of external cues is of importance for the localization of other organisms (prey, predators and mates), and is mediated by an array of mechano- and chemoreceptors located on the paired antennules (A1).We investigated the morphology and distribution pattern of A1 sensory structures in the adult female of Clausocalanus furcatus (Copepoda: Calanoida) using different techniques (camera lucida, scanning and transmission electron microscopy and laser scanning confocal microscopy) each focusing on a specific aspect of the structures analysed. Integration of the information collected shows that C. furcatus possesses an array of mechanical, chemical and dual-function sensors over its A1, by which the copepod can detect different stimuli from the environment. Results are discussed in the light of the unique swimming behaviour displayed by this widespread epipelagic copepod.

Abstract:

Little is known about the diversity of Calanoida, Copepoda, in different habitats of the north-western Red Sea. In this study, biodiversity of Calanoida, Copepoda, during the cold and warm seasons of 2017, were observed at 12 stations belonging to four different habitats (coral reef (CR), sheltered shallow lagoons (SSL), seagrass (SG), and open deep-water (ODW) habitats) in the Hurghada shelf, north-western Red Sea. SSL habitats were the most affected by environmental conditions, especially temperature, salinity, and depth. Some calanoid species were restricted to certain habitats, others were adapted to live in more than one habitat, while some species showed a wide distribution in all habitats. ODW habitats showed maximum diversity and density of the calanoid species. The effects of temperature and salinity were distinct in the SG and SSL. The results clearly showed that different Red Sea habitats affected the biodiversity of calanoid copepods.

Abstract:

The zooplankton assemblages in Chilean lakes are characterized by their markedly low species numbers and dominance of calanoid copepods. Nevertheless, the effects of zooplanktivorous fish predation on zooplankton size in these communities have not yet been studied in detail. The aim of the present study was to analyse the total length in the main groups of zooplanktonic crustaceans in Chilean lakes: Copepoda: Calanoida, and Cladocera: Daphniidae, as well as “small cladocerans” (specifically the families Bosminidae and Chydoridae). The results revealed that in the presence of fish, total body length decreased significantly for calanoid copepods, whereas for other groups that presence has no significant effect. In sites with fishes, daphniids are significantly larger in comparison with the other groups of the zooplankton community, whereas in sites without fishes calanoids are significant larger in comparison with those other groups. These results would indicate that calanoids would be the main prey for zooplanktivorous fishes in Chilean lakes. Similar results have been reported for Argentinean Patagonian lakes.

Abstract:

Copepoda adalah golongan crustacean yang dapat dijadikan sebagai pakan alami untuk larva ikan. Secara umum copepoda tergolong dalam empat ordo yaitu Calanoida, Cyclopoida, Harpacticoida, dan Monstrilidae. Di Balai Besar Riset Perikanan Budidaya Laut, Gondol, Copepoda yang dibudidayakan adalah jenis Harpacticoida yaitu Tisbe sp. yang pemeliharaannya dikerjakan dalam bak terkontrol. Copepod ini diberi pakan berupa fitoplankton, scoot’s emulsion, pelet ikan, dan ragi, serta sedikit penambahan probiotik. Pembatas selama budidaya adalah sulitnya produksi naupli copepoda secara massal, hal ini dikarenakan waktu bertelur yang tidak seragam antara individu copepoda, sehingga tidak bisa ditentukan waktu yang tepat untuk panen nauplii secara besarbesaran. Pembatas kedua adalah lambatnya reproduksi copepoda yaitu 14 hari jika dibandingkan dengan rotifer yang hanya dua hari. Pembatas ketiga adalah adanya spesies asing atau predator yang menyerang copepoda pada kondisi tertentu, seperti tingginya nutrisi pakan pada bak pemeliharaan.

Abstract:

Calanoid copepods are extremely successful inhabitants of marine, brackish and freshwater plankton. Morphological data are used to arrive at a first, parsimony-based phylogeny for the calanoid copepods. Each family is represented by at least one exemplar, typically a recognised plesiomorphic species. The Epacteriscidae are sister to all other calanoid copepods – an observation that brings into question the concept of an Epacteriscoidea that includes the Ridgewayiidae. The monophyly of the Augaptiloidea, Centropagoidea, Clausocalanoidea and Pseudocyclopoidea is corroborated. The current analysis suggests there may be two major clades, one containing the Augaptiloidea, Centropagoidea and possibly the Pseudocyclopoidea and Ridgewayiidae and the other including the Megacalanidae, Calanidae/Paracalanidae, Bathypontioidea, Eucalanoidea, Ryocalanoidea, Spinocalanoidea and Clausocalanoidea. The relationships of the Pseudocyclopidae, Boholinidae, and Ridgewayiidae to the Centropagoidea/Augaptiloidea clade received low nodal support. Monophyly of an enlarged Bathypontioidea (including the Fosshageniidae) is proposed. A monophyletic Megacalanoidea is not retrieved. The nature of the inferred ancestral Calanoida is discussed. New evolutionary series are proposed for the female genitalia (including several losses and regaining of seminal receptacles, and independent losses of the genital operculum – once lost it is never regained) and leg 1 endopod. Paedomorphosis appears to be a dominant process in the evolution of the Calanoida.

Abstract:

Abstract The genus Pseudodiaptomus is represented by 19 species in Philippine coastal waters. Of all these species found in the Philippines, P. brehmi Kiefer, 1938 is the only known truly freshwater pseudodiaptomid endemic to this country, which was originally described from Lake Naujan, Mindoro Island. After numerous attempts to find it in its type locality, we concluded that the former is no longer extant in this lake and has now been displaced by the invasive Neotropical calanoid Arctodiaptomus dorsalis (Marsh, 1907). Sampling in Lake Taal, on the nearby island of Luzon, resulted in the surprise discovery of P. brehmi populations coexisting with A. dorsalis. This rediscovery of P. brehmi in Lake Taal and its absence from its type locality, necessitate this report as well as the species’ morphological redescription.

Full text

Abstract:

The Megacalanidae were revised based on new and archived material. Taxonomic confusion that has existed in the family is discussed and a method is suggested for stabilising names. A detailed examination of the morphology of this family, using the light microscope, has added further useful characters that distinguish genera and species. The added, hitherto undescribed species include character states incompatible with aspects of previous generic definitions (e.g. presence or absence of setae on the maxillule coxal endite). Nevertheless, the cladistic and molecular analyses confirmed that there are at least four monophyletic clades mostly with high bootstrap support. These clades represent already defined genera, one of which [Elenacalanus nom. nov. (nomen novum)] replaces the preoccupied name Heterocalanus Wolfenden, 1906. Four previously described species have been re-assigned to Elenacalanus in new combinations: E. princeps (Brady, 1883), E. eltaninae (Björnberg, 1968), E. sverdrupi (Johnson, 1958) and E. inflatus (Björnberg, 1968). Eleven new species are described: three Megacalanus, one Bradycalanus, six Bathycalanus, and one Elenacalanus nom. nov. Bradycalanus pseudotypicus enormis Björnberg, 1968 has been raised to species status based on genetic data although it can be only be distinguished morphologically from Br. typicus by its large size. All four genera are differentially diagnosed and keys are provided to the genera and species. We confirm that all male right antennules are geniculate in the Megacalanidae. Thirteen males are known. Of these males, eight are newly described (M. frosti n. sp., M. ericae n. sp., M. ohmani n. sp., Bathycalanus bradyi (Wolfenden, 1905a), Ba. dentatus n. sp., Ba. milleri n. sp., Ba. unicornis Björnberg, 1968, and Elenacalanus tageae n. sp.). We cannot be absolutely certain that the correct males have been assigned to the appropriate female so our decisions await testing with new data. The cladistic analysis provides the first morphology-based phylogeny. This scheme served as a working hypothesis which was tested and corroborated using the newly gathered molecular data. Vertical and horizontal distributions are summarised.

Abstract:

Most studies on the pore signature of calanoid copepods have been made on adult femalessemicolon very little is known of the ontogenetic development of the pore signatures and their sexual differences. Males, females and copepodids of five species in the metridinid genus Pleuromamma are examined. Interspecific differences in the pore signatures occur as early as copepodid III. Differences in the signatures of the copepodids arise from two sources: (1) species-specific rates of development of the adult signaturesemicolon (2) development of the species-specific components of the adult signature. The cephalosomal signature is complete in copepodid V, and the metasomal and urosomal signatures are complete in copepodid VI, the adult stage. Sexual differences in the pore signature are found in copepodid IV and are primarily evident in the urosome of the adult. The species-specific components of the urosomal signature are greater in the female than in the male.

The effect of food concentration on the reproductive success of the copepod Centropages typicus (Copepoda: Calanoida) was studied in the laboratory. Three different regimes of food were tested: absence of food, natural food conditions and a food media enriched with an algal culture. The results showed significant differences in egg production rate between regimes of food, but no significant differences in egg viability. A rapid response (24 h) in egg production rate to increment in the quantity of food was noted. Hatching success was not affected by food conditions prevailing during the incubations.

Abstract:

We present an updated checklist of the Diaptomidae of China, based on a literature review and on original field data from all over China during 2012-2016. A total of 19 genera and 56 species have been recorded. Neutrodiaptomus has the highest species richness (10 species), followed by Arctodiaptomus (9 species). Only one species each of Eudiaptomus, Mixodiaptomus, Eodiaptomus, Dentodiaptomus, Dolodiaptomus, Allodiaptomus, Karstodiaptomus, Metadiaptomus and Paradiaptomus was found. The taxonomic status of 16 species was revised: one wrongly attributed genus, Argyrodiaptomus, was corrected to Sinodiaptomus. First records for China include Arctodiaptomus parvispineus and one new cave-dwelling genus, Karstodiaptomus, is added. One Latin name from Shen & Sung’s book (1979) is corrected. Remarks on nomenclature and taxonomic issues are supplemented with information on the geographical distribution of the various species within China.

Abstract:

AbstractAdult specimens of Acartia bifilosa have been examined under SEM and evidence of the presence of rostral filaments in this species is confirmed. The suggestion of Shim & Choi (1996) to change its taxonomic position from the subgenus Acanthacartia to the subgenus Acartiura is therefore rejected. This report clearly shows that A. bifilosa should remain in its current taxonomic position, although further taxonomic/genetic studies on this species are necessary. Des specimens adultes d' Acartia bifilosa ont ete examines sous MEB et la presence de filaments rostraux chez cette espece est confirmee. La suggestion de Shim & Choi (1996) de deplacer sa position taxonomique du sous-genre Acanthacartia au sous-genre Acartiura est de ce fait rejetee. Ces observations montrent clairement qu' A. bifilosa devrait conserver sa position taxonomique courante, bien que des etudes taxonomiques/genetiques complementaires sur cette espece soient necessaires.

Abstract:

In a population of the common freshwater copepod Leptodiaptomus minutus Lilljeborg, 7.3% of adult females exhibited male secondary sexual characteristics. Although these masculinized or intersex females had the internal morphology of normal females, they possessed one or rarely two normal geniculate male antennules, and in a few instances male fifth legs. The sex ratio of normal adult males to females in the population was 1:1. No differences in body size among normal males, normal females, and masculinized females were found. Antennule lengths of males and masculinized females were not significantly different from one another; however, normal females had longer antennules than either males or masculinized females. Mating experiments indicated that masculinized females were functionally female and they were able to mate with normal males to produce offspring that were normal or masculinized. The occurrence of intersex copepods in lakes of North America may be more widespread than we now recognize because they can be easily overlooked or mistaken for normal adults.

Abstract:

Abstract Coastal Lake Bardawil (Egypt) is one of the largest hypersaline lakes in the world. In 2009–2010, the authors studied composition, distribution and seasonal dynamics of copepods at 12 sites. A total of 10 species of copepods were recorded in zooplankton during the study period, including 5 Calanoida, 2 Cyclopoida and 3 Harpacticoida. Oithona nana was the most common and most abundant species. All copepods in the lake can be divided into three groups: 1) planktic species that form stable populations, 2) species of Mediterranean plankton incidentally entering the lake from the adjacent sea area, 3) benthic Cyclopoida and Harpacticoida that can be abundant in plankton. Two species – Acartia tonsa and A. danae were recorded here for the first time. The total abundance of copepods in the lake was significantly higher (90 times on average) compared to that observed in 2008–2009 in the waters of the Egyptian Mediterranean Sea. Since 1967, the complex of common and dominant copepod species in the lake has changed significantly. The total average annual copepod abundance varied: in 2002 – it was about 4000 ind. m−3, in 2004 – 152 000 ind. m−3, in 2005 – about 25 300 ind. m−3, and in 2009–2010 – about 56 000 ind. m−3.

Abstract:

Three new species of copepod crustaceans are described from material collected from anchialine and brackish habitats inand around the village of Walengkabola on the coast of Muna Island, to the southeast of Sulawesi. A new species of cy-clopoid, Paracyclopina sacklerae n. sp., was described from material collected from the tidal inflow entering into the bot-tom of sinkholes a few metres inland from the shoreline. Detailed comparisons are made with Paracyclopina orientalis(Lindberg, 1941), n. comb., a closely related congener here transferred from its original genus Cyclopetta Sars, 1913. Theassignment of Paracyclopina Smirnov, 1935 to the family Cyclopettidae is followed here despite uncertainty over the va-lidity of some of the families created by the break up of the former Cyclopinidae. Two new species of Boholina Fosshagen& Iliffe, 1989 are described, based on material from the same sinkholes and from caves located up to 700m inland fromthe coast and exhibiting further reduced salinity down to 1.8 ppt. One species, B. parapurgata n. sp., is very closely relatedto B. purgata Fosshagen & Iliffe, 1989 from Bohol island in the Philippines, the other B. munaensis n. sp., is very closelyrelated to B. crassicephala Fosshagen & Iliffe, 1989 also from Bohol island, but a number of fine scale differences in the leg 5 of both sexes are recognised in each case. Keys to valid species of both genera are provided.

Abstract:

The complete postembryonic development ofPseudodiaptomus koreanusSoh, Kwon, Lee & Yoon, 2012 (Copepoda, Calanoida) comprises six naupliar and six copepodid stages of which the last is the adult. The descriptions were based on laboratory-reared nauplii and copepodids and also on copepodids collected by plankton net, all sourced from the Seomjin River estuary in southern Korea. Nauplius and copepodid stages ofP. koreanusare very similar to those of the previously described species ofPseudodiaptomus. However, of all the characteristics, it is the shape and number of setae on the terminal segments of the antennules in the late naupliar stages, and the shape and somites of the body and the segmentation and number of setae of the exo- and endopods of the swimming legs from copepodid stages I to V, which are most useful in reconstructing relationships among the eightPseudodiaptomusspp. reared until now.

Abstract:

The diversity of freshwater zooplankton is still little known in Mexico, particularly in reference to insular zooplankton communities. Diaptomid copepods (Crustacea: Copepoda: Calanoida) are a widespread group worldwide, and Mexico harbours high diaptomid diversity. Based on a recent sampling of freshwater zooplankton on a Caribbean Island of Mexico, we present the first record of a diaptomid copepod from an island freshwater ecosystem. It shows the well-known tendency of Neotropical diaptomids to have restricted distributional patterns and high levels of endemism. The species recorded, Mastigodiaptomus ha (Cervantes-Martínez, 2020) appears to have a restricted distribution in the Yucatan Peninsula (YP), and the island as well. In order to explore potential differences between the island and continental populations of this species, its phenetic and genetic diversity was analysed by performing morphological comparisons and also by exploring differences of the habitat conditions and genetic sequences (CO1 gene). Our analysis revealed a low (average = 0.33%) genetic divergence between both populations; likewise, both the morphology and habitat conditions closely resemble each other in these two populations. The low genetic divergence between the continental and island populations of M. ha suggests an early common origin of the species in the geological history of the YP.

Abstract:

Karstodiaptomus sheni n. gen., n. sp. is a new stygobiotic species of Calanoida (Crustacea: Copepoda), described from a cave in Yunnan Province, China. It is the first record of stygobiotic calanoids from China and the fourth species from Asia. To accommodate the new species, a new genus, Karstodiaptomus n. gen., was erected. The new species is distinguished from other representatives in the subfamily Speodiaptominae Borutzky, 1962 by the number of segments in the swimming legs P1–P4 (Exp + Enp) as: 2+2, 2+2, 2+2, 3+2, the armature of the antennule, maxilla, maxilliped, and the structure of the fifth leg. The position of the new species in the subfamily Speodiaptominae is discussed, and a brief note on its ecology is added.
