A first checklist of the Caribbean harpacticoid copepods is provided herein; it is based on records in the literature and on our own data. Records from the adjacent Bahamas zone were also included. This complete list includes 178 species; the species recorded in the Caribbean and the Bahamas belong to 33 families and 94 genera. Overall, the most speciose family was the Miraciidae (27 species), followed by the Laophontidae (21), Tisbidae (17), and Ameiridae (13). Up to 15 harpacticoid families were represented by one or two species only. -
Early Miocene Amber Inclusions from Mexico Reveal Antiquity Of
www.nature.com/scientificreports OPEN Early Miocene amber inclusions from Mexico reveal antiquity of mangrove-associated copepods Received: 29 March 2016 Rony Huys1, Eduardo Suárez-Morales2, María de Lourdes Serrano-Sánchez3, Accepted: 16 September 2016 Elena Centeno-García4 & Francisco J. Vega4 Published: 12 October 2016 Copepods are aquatic microcrustaceans and represent the most abundant metazoans on Earth, outnumbering insects and nematode worms. Their position of numerical world predominance can be attributed to three principal radiation events, i.e. their major habitat shift into the marine plankton, the colonization of freshwater and semiterrestrial environments, and the evolution of parasitism. Their variety of life strategies has generated an incredible morphological plasticity and disparity in body form and shape that are arguably unrivalled among the Crustacea. Although their chitinous exoskeleton is largely resistant to chemical degradation copepods are exceedingly scarce in the geological record with limited body fossil evidence being available for only three of the eight currently recognized orders. The preservation of aquatic arthropods in amber is unusual but offers a unique insight into ancient subtropical and tropical ecosystems. Here we report the first discovery of amber-preserved harpacticoid copepods, represented by ten putative species belonging to five families, based on Early Miocene (22.8 million years ago) samples from Chiapas, southeast Mexico. Their close resemblance to Recent mangrove-associated copepods highlights the antiquity of the specialized harpacticoid fauna living in this habitat. With the taxa reported herein, the Mexican amber holds the greatest diversity of fossil copepods worldwide. Copepods are among the most speciose and morphologically diverse groups of crustaceans, encompassing 236 families and roughly 13,970 described species. -

Seasonal changes in prey composition and predatory impact were investigated by analysing stomach contents. The dominant prey organisms of A. aurita were several cladoceran species (Bosmina coregoni maritima, Evadne nordmanni and Podon spp.). They represented up to 93% of the food organisms. Bivalve larvae and copepods (Centropages hamatus, Temora longicornis, Acartia spp., Pseudocalanus acuspes, Eurytemora hirundoides and Oithona similis) were less frequently found. Nauplii and copepodites I-III were not eaten by the medusae neither were fish eggs and larvae used as prey. Based on average medusae and zooplankton abundance, the predatory impact was very low. In August, when mean abundance of A. aurita was highest, only 0.1% of the copepod and 0.54% of the cladoceran standing stock were eaten per day. However in regions -

Emergent and Non-Emergent Species of Harpacticoid Copepods Can Be Recognized Morphologically
MARINE ECOLOGY PROGRESS SERIES Vol. 266: 195–200, 2004 Published January 30 Mar Ecol Prog Ser Emergent and non-emergent species of harpacticoid copepods can be recognized morphologically David Thistle*, Linda Sedlacek Department of Oceanography, Florida State University, Tallahassee, Florida 32306-4320, USA ABSTRACT: Emergence — the active movement of benthic organisms into the water column and back — has consequences for many ecological processes, e.g. benthopelagic coupling. Harpacticoid copepods are conspicuous emergers, but technical challenges have made it difficult to determine which species emerge, impeding the study of the ecology and evolution of the phenomenon. We examined data on harpacticoid emergence from 2 sandy, subtidal sites (~20 m deep) in the northern Gulf of Mexico and found 6 species that always emerged and 2 species that never emerged. An examination of the locomotor appendages revealed that the number of segments in the endopods of pereiopods 2–4 and the number of setae and spines on the distal exopod segments of pereiopods 2–4 can be used to distinguish emergers from non-emergers. We then successfully used these characters to predict the behavior of 3 additional species. Certain morphological differences may therefore allow differentiation of emergers from non-emergers.

Abstract Inversions of the origin of replication (ORI) of mitochondrial genomes produce asymmetrical mutational pressures that can cause artefactual clustering in phylogenetic analyses. It is therefore an absolute prerequisite for all molecular evolution studies that use mitochondrial data to account for ORI events in the evolutionary history of their dataset. -

The Vtg gene, mRNA and protein regulation involve several environmental factors and physiological processes, including gonadal maturation and moult stages, among others. Once the Vtg gene, mRNAs and protein are obtained, it is possible to establish the relationship between the elements that participate in their regulation, which could either be species-specific, or tissue-specific. This work is a systematic analysis that compares the similarities and differences of Vtg genes, mRNA and Vtg between the crustacean species reported in databases with respect to that obtained from the transcriptome of Callinectes arcuatus, C. toxotes, Penaeus stylirostris and P. vannamei obtained with MiSeq sequencing technology from Illumina. Those analyses confirm that the Vtg obtained from selected species will serve to understand the process of vitellogenesis in crustaceans that is important for fisheries and aquaculture. RESUMEN La vitelogénesis de los crustáceos es un proceso que involucra la vitelina, producida a través de la endoproteólisis de su precursor llamado Vitelogenina (Vtg). -
Reported Siphonostomatoid Copepods Parasitic on Marine Fishes of Southern Africa
REPORTED SIPHONOSTOMATOID COPEPODS PARASITIC ON MARINE FISHES OF SOUTHERN AFRICA BY SUSAN M. DIPPENAAR1) School of Molecular and Life Sciences, University of Limpopo, Private Bag X1106, Sovenga 0727, South Africa ABSTRACT Worldwide there are more than 12000 species of copepods known, of which 4224 are symbiotic. Most of the symbiotic species belong to two orders, Poecilostomatoida (1771 species) and Siphonos- tomatoida (1840 species). The order Siphonostomatoida currently consists of 40 families that are mostly marine and infect invertebrates as well as vertebrates. In a report on the status of the marine biodiversity of South Africa, parasitic invertebrates were highlighted as taxa about which very little is known. A list was compiled of all the records of siphonostomatoids of marine fishes from southern African waters (from northern Angola along the Atlantic Ocean to northern Mozambique along the Indian Ocean, including the west coast of Madagascar and the Mozambique channel). Quite a few controversial reports exist that are discussed. The number of species recorded from southern African waters comprises a mere 9% of the known species. RÉSUMÉ Dans le monde, il y a plus de 12000 espèces de Copépodes connus, dont 4224 sont des symbiotes. La plupart de ces espèces symbiotes appartiennent à deux ordres, les Poecilostomatoida (1771 espèces) et les Siphonostomatoida (1840 espèces). L’ordre des Siphonostomatoida comprend actuellement 40 familles, qui sont pour la plupart marines, et qui infectent des invertébrés aussi bien que des vertébrés. Dans un rapport sur l’état de la biodiversité marine en Afrique du Sud, les invertébrés parasites ont été remarqués comme étant très peu connus. -

[email protected] 1. Brief definition of the group and main diagnosing characters The Harpacticoida is one of the orders of the subclass Copepoda, and includes mainly free-living epibenthic aquatic organisms, although many species have successfully exploited other habitats, including semi-terrestial habitats and have established symbiotic relationships with other metazoans. Harpacticoids have a size range between 0.2 and 2.5 mm and have a podoplean morphology. This morphology is char- acterized by a body formed by several articulated segments, metameres or somites that form two separate regions; the anterior prosome and the posterior urosome. The division between the urosome and prosome may be present as a constriction in the more cylindric shaped harpacticoid families (e.g. Ectinosomatidae) or may be very pronounced in other familes (e.g. Tisbidae). The adults retain the central eye of the larval stages, with the exception of some underground species that lack visual organs. The harpacticoids have shorter first antennae, and relatively wider urosome than the copepods from other orders. The basic body plan of harpacticoids is more adapted to life in the benthic environment than in the pelagic environment i.e. they are more vermiform in shape than other copepods. Harpacticoida is a very diverse group of copepods both in terms of morphological diversity and in the species-richness of some of the families.
