AbstractIncreasing knowledge of the biodiversity of parasitic copepods in the Argentinean Sea will provide a baseline against which changes in the distribution of marine biota can be detected. We provide new information on the distribution of 13 known species of parasitic copepods gathered from 11 species of marine fishes from Argentinean Sea, including 7 new host records and 9 new locality records. These species are: Bomolochus globiceps (Vervoort et Ramírez, 1968) and Nothobomolochus cresseyi Timi et Sardella, 1997 (Bomolochidae Sumpf, 1871); Brasilochondria riograndensis Thatcher et Pereira, 2004 (Chondracanthidae Milne Edwards, 1840); Taeniacanthus lagocephali Pearse, 1952 (Taeniacanthidae Wilson, 1911); Caligus rogercresseyi Boxshall et Bravo, 2000 and Metacaligus uruguayensis (Thomsen, 1949) (Caligidae Burmeister, 1835); Hatschekia conifera Yamaguti, 1939 (Hatschekiidae Kabata, 1979); Clavellotis pagri (Krøyer, 1863), Clavella adunca (Strøm, 1762), Clavella bowmani Kabata, 1963 and Parabrachiella amphipacifica Ho, 1982 (Lernaeopodidae Milne Edwards, 1840), and Lernanthropus leidyi Wilson, 1922 and Lernanthropus caudatus Wilson, 1922 (Lernanthropidae Kabata, 1979). A list of host species lacking parasitic copepods, for which large samples were investigated by the authors, is also provided in order to compare in future surveys.

AbstractThe mechanosensory lateral line of fishes is a flow sensing system and supports a number of behaviors, e.g. prey detection, schooling or position holding in water currents. Differences in the neuromast pattern of this sensory system reflect adaptation to divergent ecological constraints. The threespine stickleback, Gasterosteus aculeatus, is known for its ecological plasticity resulting in three major ecotypes, a marine type, a migrating anadromous type and a resident freshwater type. We provide the first comparative study of the pattern of the head lateral line system of North Sea populations representing these three ecotypes including a brackish spawning population. We found no distinct difference in the pattern of the head lateral line system between the three ecotypes but significant differences in neuromast numbers. The anadromous and the brackish populations had distinctly less neuromasts than their freshwater and marine conspecifics. This difference in neuromast number between marine and anadromous threespine stickleback points to differences in swimming behavior. We also found sexual dimorphism in neuromast number with males having more neuromasts than females in the anadromous, brackish and the freshwater populations. But no such dimorphism occurred in the marine population. Our results suggest that the head lateral line of the three ecotypes is under divergent hydrodynamic constraints. Additionally, sexual dimorphism points to divergent niche partitioning of males and females in the anadromous and freshwater but not in the marine populations. Our findings imply careful sampling as an important prerequisite to discern especially between anadromous and marine threespine sticklebacks.

Prochristianella cairae n. sp. is described from the spiral intestines of two species of bamboo sharks, Chiloscylliumpunctatum Müller & Henle and Chiloscyllium indicum (Gmelin) (Hemiscyllidae) off the coast of Malaysian Borneo. Thespecies is distinguished from congeners by enlarged microtriches covering the whole scolex peduncle, a uniquearrangement of hooks on the basal swelling, a dissimilar number of hooks in each principle row in the metabasal armatureand hook files 1 and 1’ not being distinctly separated. Prochristianella jensenae n. sp. is described from the spiralintestines of three species of whiptail stingrays, Pastinachus solocirostris Last & Manjaji-Matsumoto, Pastinachus atrus(Macleay) and Pastinachus gracilicaudus Last & Manjaji-Matsumoto (Dasyatidae) from coastal waters off Indonesianand Malaysian Borneo and Western Australia, from Himantura uarnak (Gmelin) (Dasyatidae) off Nickol Bay, WesternAustralia and from Rhinoptera neglecta Ogilby (Myliobatidae) off Weipa, Queensland, Australia. This species lacksgland-cells within the tentacular bulbs, one of the most distinctive features of this family. Prochristianella kostadinovaen. sp. is described from the spiral intestines of Himantura uarnak 2 (Dasyatidae) (sensu Naylor et al. 2012) from the Gulfof Carpenteria. It differs from congeners in its metrical data, a metabasal tentacular armature with 10 hooks per principlerow, hooks 1(1’) being uncinate with an elongate base and widely spaced and hooks 4(4’) smaller than neighbouring hooks3(3’) and 5(5’). Prochristianella scholzi n. sp. is described from specimens of the Taeniura lymma species complex(Dasyatidae) (sensu Naylor et al. 2012) from three localities in Malaysian and Indonesian Borneo. This species has arraysof billhooks on the basal swelling, but differs from similar congeners in having very few, tiny gland-cells within thetentacular bulbs and a metabasal tentacular armature with 9–10 hooks per half spiral row and hooks 4(4’) being muchsmaller than the neighbouring hooks 3(3’) and 5(5’). Examinations of new material from northern Australia andIndonesian and Malaysian Borneo provided additional information on Prochristianella aciculata Beveridge & Justine,2010, Prochristianella butlerae Beveridge, 1990 and Prochristianella clarkeae Beveridge, 1990. In total, 17, 7 and 29(respectively) new host records and 14, 9 and 28 (respectively) new locality records are added. These records extend thegeographical range of all three species in the Australasian region and also represents the first record of P. aciculata fromAustralian waters and the first record of P. butlerae from the Indo-Malayan region. Prochristianella clarkeae is the least host specific taxon within Prochristianella, infecting 43 different host species.

The Impact

ABSTRACT The complete genome sequence of an RNA virus was assembled from RNA sequencing of virus particles purified from threespine stickleback intestine tissue samples. This new virus is most closely related to the Eel picornavirus and can be assigned to the genus Potamipivirus in the family Picornaviridae. Its unique genetic properties are enough to establish a new species, dubbed the Threespine Stickleback picornavirus (TSPV). Due to their broad geographic distribution throughout the Northern Hemisphere and parallel adaptation to freshwater, threespine sticklebacks have become a model in evolutionary ecology. Further analysis using diagnostic PCRs revealed that TSPV is highly prevalent in both anadromous and freshwater populations of threespine sticklebacks, infects almost all fish tissues, and is transmitted vertically to offspring obtained from in vitro fertilization in laboratory settings. Finally, TSPV was found in Sequence Reads Archives of transcriptome of Gasterosteus aculeatus, further demonstrating its wide distribution and unsought prevalence in samples. It is thus necessary to test the impact of TSPV on the biology of threespine sticklebacks, as this widespread virus could interfere with the behavioral, physiological, or immunological studies that employ this fish as a model system. IMPORTANCE The threespine stickleback species complex is an important model system in ecological and evolutionary studies because of the large number of isolated divergent populations that are experimentally tractable. For similar reasons, its coevolution with the cestode parasite Schistocephalus solidus, its interaction with gut microbes, and the evolution of its immune system are of growing interest. Herein we describe the discovery of an RNA virus that infects both freshwater and anadromous populations of sticklebacks. We show that the virus is transmitted vertically in laboratory settings and found it in Sequence Reads Archives, suggesting that experiments using sticklebacks were conducted in the presence of the virus. This discovery can serve as a reminder that the presence of viruses in wild-caught animals is possible, even when animals appear healthy. Regarding threespine sticklebacks, the impact of Threespine Stickleback picornavirus (TSPV) on the fish biology should be investigated further to ensure that it does not interfere with experimental results.

Black-necked swans (Cygnus melanocoryphus) are endemic to the southern cone of South America. Their range extends from Brazil and Paraguay south to Argentina and Chile. A total of 16 parasite species were collected from 7 swans from the Biobio region, Chile, of which 12 are new records for Chile and 11 represent new host records, Echinostoma trivolvis, Paranomostomum sp., Microsomacanthus sp., Nadejdolepis sp., Retinometra sp., Avioserpens sp., Capillaria skrjabini, Ingrassia cygni, Anatoecus penicillatus, A. icterodes and A. keymeri. A checklist is presented that summarizes sites of infections, localities, life cycles and their intermediate hosts (if known), and the pertinent references to demonstrate the wide diversity of parasites of black-necked swans. Our review of the existing literature (23 publications) along with our own records provided information on a total of 18 families and 27 genera, including 33 described species (some only identified to genus), of which 11 were recorded only in Chile (8 endoparasites and 3 ectoparasites), and 6 only in Argentina (4 endoparasites and 2 ectoparasites). Five parasites are known only from captive swans in European zoos. Parasites recorded from C. melanocoryphus include 23 helminths and 10 ectoparasites (one leech and 9 arthropods).
