Additions to and Revisions of the Amphipod (Crustacea: Amphipoda) Fauna of South Africa, with a List of Currently Known Species from the Region
Additions to and revisions of the amphipod (Crustacea: Amphipoda) fauna of South Africa, with a list of currently known species from the region Rebecca Milne Department of Biological Sciences & Marine Research Institute, University of CapeTown, Rondebosch, 7700 South Africa & Charles L. Griffiths* Department of Biological Sciences & Marine Research Institute, University of CapeTown, Rondebosch, 7700 South Africa E-mail: [email protected] (with 13 figures) Received 25 June 2013. Accepted 23 August 2013 Three species of marine Amphipoda, Peramphithoe africana, Varohios serratus and Ceradocus isimangaliso, are described as new to science and an additional 13 species are recorded from South Africa for the first time. Twelve of these new records originate from collecting expeditions to Sodwana Bay in northern KwaZulu-Natal, while one is an introduced species newly recorded from Simon’s Town Harbour. In addition, we collate all additions and revisions to the regional amphipod fauna that have taken place since the last major monographs of each group and produce a comprehensive, updated faunal list for the region. A total of 483 amphipod species are currently recognized from continental South Africa and its Exclusive Economic Zone . Of these, 35 are restricted to freshwater habitats, seven are terrestrial forms, and the remainder either marine or estuarine. The fauna includes 117 members of the suborder Corophiidea, 260 of the suborder Gammaridea, 105 of the suborder Hyperiidea and a single described representative of the suborder Ingolfiellidea. -

Bolbometopon Muricatum) in North Maluku Waters Muhammad J
DNA barcode and phylogenetics of green humphead parrotfish (Bolbometopon muricatum) in North Maluku waters Muhammad J. Achmad, Riyadi Subur, Supyan, Nebuchadnezzar Akbar Faculty of Fisheries and Marine Sciences, Khairun University, Ternate, North Maluku, Indonesia. Corresponding author: N. Akbar, [email protected] Abstract. The green humphead parrotfish (Bolbometopon muricatum) is one of the large species inhabiting coral reefs in North Maluku waters, Indonesia. The declining fish populations due to excessive fishing has caused the green humphead parrotfish to be listed in the Red List of IUCN in the vulnerable category since 2012. The species could be highly endangered, bordering extinction in the future. Studies on the genetic identification of green humphead parrotfish could be considered critical in the policy of sustainable conservation and fish culture. This research is designed for the identification and analysis of the genetic relationship of green humphead parrotfish based on the COI (cytochrome-c-oxidase subunit I) gene. DNA samples were collected from 4 locations in North Maluku, Ternate Island, Morotai Island, Bacan Island and Sanan Island. The DNA from samples was extracted and the COI gene was amplified using PCR (Polymerase Chain Reaction). Furthermore, the amplicon was sequenced to observe the similarities with the NCBI GenBank database. The results of this study showed that the green humphead parrotfish from this study had high similarities (98-100%) with the green humphead parrotfish with the reference access no. KY235362.1. Based on the phylogenetic tree, the green humphead parrotfish originating from North Maluku has a genetic relationship with the green humphead parrotfish from the database, but with different molecular characters. -

To address this knowledge gap, we provide a holistic trophic characterization of a jelly web in the eastern tropical Atlantic, based on δ13C and δ15N stable isotope analysis of a unique gelatinous zooplankton sample set. The jelly web covered most of the isotopic niche space of the entire planktonic oceanic food web, spanning > 3 tro- phic levels, ranging from herbivores (e.g., pyrosomes) to higher predators (e.g., ctenophores), highlighting the diverse functional roles and broad possible food web relevance of gelatinous zooplankton. -

Buser, B.Sc. Fairbanks, Alaska May 2014 v Abstract The sculpin subfamily Oligocottinae is a group of 17 nearshore species and is noteworthy for the fact that it contains both intertidal and subtidal species, copulating and non- copulating species, and many species with very broad geographic ranges. These factors, as well as the consistency with which the constituent genera have been grouped together historically, make the Oligocottinae an ideal group for the study of the evolution of a reproductive mode known as internal gamete association (IGA), which is unique to sculpins. I conducted a phylogenetic study of the oligocottine sculpins based on an extensive molecular dataset consisting of DNA sequences from eight genomic regions. From the variability present in those sequences, I inferred phylogenetic relationships using parsimony, maximum likelihood, and Bayesian inference. Results of these phylogenetic analyses show that some historical taxonomy and classifications require revision to align taxonomy with evolutionary relatedness. -
Evolution of Large Body Size in Abalones (Haliotis): Patterns and Implications
Paleobiology, 31(4), 2005, pp. 591±606 Evolution of large body size in abalones (Haliotis): patterns and implications James A. Estes, David R. Lindberg, and Charlie Wray Abstract.ÐKelps and other ¯eshy macroalgaeÐdominant reef-inhabiting organisms in cool seasÐ may have radiated extensively following late Cenozoic polar cooling, thus triggering a chain of evolutionary change in the trophic ecology of nearshore temperate ecosystems. We explore this hypothesis through an analysis of body size in the abalones (Gastropoda; Haliotidae), a widely distributed group in modern oceans that displays a broad range of body sizes and contains fossil representatives from the late Cretaceous (60±75 Ma). Geographic analysis of maximum shell length in living abalones showed that small-bodied species, while most common in the Tropics, have a cosmopolitan distribution, whereas large-bodied species occur exclusively in cold-water ecosys- tems dominated by kelps and other macroalgae. The phylogeography of body size evolution in extant abalones was assessed by constructing a molecular phylogeny in a mix of large and small species obtained from different regions of the world. This analysis demonstrates that small body size is the plesiomorphic state and largeness has likely arisen at least twice. Finally, we compiled data on shell length from the fossil record to determine how (slowly or suddenly) and when large body size arose in the abalones. These data indicate that large body size appears suddenly at the Miocene/Pliocene boundary. Our ®ndings support the view that ¯eshy-algal dominated ecosys- tems radiated rapidly in the coastal oceans with the onset of the most recent glacial age. -

Checklist of marine demersal fishes captured by the pair trawl fisheries in Southern (RJ-SC) Brazil. Biota Neotropica. 19(1): e20170432. http://dx.doi.org/10.1590/1676-0611-BN-2017-0432 Abstract: Demersal fishery resources are abundant on continental shelves, on the tropical and subtropical coasts, making up a significant part of the marine environment. Marine demersal fishery resources are captured by various fishing methods, often unsustainably, which has led to the depletion of their stocks. In order to inventory the marine demersal ichthyofauna on the Southern Brazilian coast, as well as their conservation status and distribution, this study analyzed the composition and frequency of occurrence of fish captured by pair trawling in 117 fishery fleet landings based in the State of São Paulo between 2005 and 2012. -
