    Helminth records from eleven species of Emoia (Sauria: Scincidae) from Oceania
    (University of Hawaii Press, 2005-10) Goldberg, Stephen R. ; Bursey, Charles R. ; Fisher, Robert N.
    As part of an ongoing study of the biogeography of helminth parasites of lizards from Oceania, 53 specimens of Emoia (11 species) were examined, as follows: E. atrocostata, E. boettgeri, E. caerulocauda, E. cyanogaster, E. cyanura, E. impar, E. nigra, E. nigromarginata, E. ponapea, E. sanfordi, E. trossula. One species of Digenea, Paradistomoides gregarium, and six species of Nematoda, Hedruris hanleyae, Maxvachonia chabaudi, Parapharyngodon maplestoni, Physalopteroides arnoensis, Spauligodon gehyrae, and Moaciria sp. indet., were found. These helminths have been reported previously from other lizard species. Seventeen new host records and eight new locality records are reported.

    A new species of Glossodoris (Mollusca: Nudibranchia), of the Glossodoris atromarginata color group, from Indonesia
    (University of Hawaii Press, 2005-10) Valdés, Ángel ; Adams, Mary Jane
    A new species, Glossodoris tibboeli Valdés & Adams, is described based on three specimens collected from Para Island and several others observed at Para, Kahakitang, and Mahengetang Islands, north of Sulawesi, Indonesia. The species is characterized by being starkly opaque white, with a dark brown, irregular dorsal strip extending from the rhinophores to the gill. Because of the coloration and external morphology the new species is compared with members of the Glossodoris atromarginata (Cuvier, 1804) color group, from which it differs by lacking a dark line around the mantle margin. The radulae of all members of the G. atromarginata color group are similar but differ from that of the new species in lacking rachidian teeth.

    False killer whale dorsal fin disfigurements as a possible indicator of long-line fishery interactions in Hawaiian Waters
    (University of Hawaii Press, 2005-10) Baird, Robin W. ; Gorgone, Antoinette M.
    Scarring resulting from entanglement in fishing gear can be used to examine cetacean fishery interactions. False killer whales (Pseudorca crassidens) are known to interact with the Hawai'i-based tuna and swordfish long-line fishery in offshore Hawaiian waters. We examined the rate of major dorsal fin disfigurements of false killer whales from nearshore waters around the main Hawaiian Islands to assess the likelihood that individuals around the main islands are part of the same population that interacts with the fishery. False killer whales were encountered on 11 occasions between 2000 and 2004, and 80 distinctive individuals were photographically documented. Three of these (3.75%) had major dorsal fin disfigurements (two with the fins completely bent over and one missing the fin). Information from other research suggests that the rate of such disfigurements for our study population may be more than four times greater than for other odontocete populations. We suggest that the most likely cause of such disfigurements is interactions with longlines and that false killer whales found in nearshore waters around the main Hawaiian Islands are part of the same population that interacts with the fishery. Two of the animals documented with disfigurements had infants in close attendance and were thought to be adult females. This implies that even with such injuries, at least some females may be able to produce offspring, despite the importance of the dorsal fin in reproductive thermoregulation.
