{"title":"Community structure of hermatypic corals at Layson Island and Lisianski Island/Neva Shoal in the Northwestern Hawaiian Islands: a new layer of scientific exploration","authors":"J. Kenyon, Casey B. Wilkinson, M. Dunlap, G. Aeby, C. Kryss","doi":"10.5479/SI.00775630.550.1","DOIUrl":"https://doi.org/10.5479/SI.00775630.550.1","url":null,"abstract":"The distribution and abundance of scleractinian corals at Laysan Island and Lisianski Island/Neva Shoal in the Northwestern Hawaiian Islands were determined by georeferenced towed-diver surveys that covered more than 56,000 m2 of benthic habitat and site-specific surveys at 33 sites during 2000 2004. Three complementary methods (towed-diver surveys, videotransects, and photoquadrats) were used to quantify percent cover of corals by genus or species at each bank and determine relative abundance. Colony counts within belt transects at fixed sites were used to assess colony density and size-class distribution. Significant differences were found between the two banks at comparable depths (7-18 m) in percent coral cover, relative abundance of the three primary genera (Porites, Montipora, and Pocillopora), and size class distributions of these genera. The coral community at Lisianski/Neva Shoal was characterized by higher percent cover, higher colony density, and a tendency towards larger colonies than the coral community at Laysan. Porites was the dominant genus at both locations, but the relative abundance of Pocillopora and Montipora differed between the banks, with Pocillopora more common at Laysan than at Lisianski/Neva Shoal, and Montipora more common at Lisiansksi/Neva Shoal than at Laysan. Notable differences were also found in the distribution of the three primary genera at the two banks. These demographic data are discussed in the context of the known history of exposure of these remote reefs to salient factors influencing the condition of coral communities including marine debris, bleaching, and disease. They provide a detailed baseline of the composition of these shallow-water communities in the early years of the 21st century that will serve as a comparative benchmark for examining long-term change. _____________________________ 1Joint Institute for Marine and Atmospheric Research and NOAA Pacific Islands Fisheries Science Center, 1125B Ala Moana Blvd., Honolulu, HI 96814 USA, Email: Jean.Kenyon@noaa.gov 2Hawaii Institute of Marine Biology, P.O.

This information is compared with more recent observations. While the slow‐breeding, surface‐nesting Herald Petrels and most of the Red‐tailed Tropicbirds, Phaethon rubricauda, have not been found again, the vegetation and other more numerous bird populations appear to have largely recovered. While some birds may breed more or less continuously, there appears to be a peak for both birds and turtles in the spring in the south of the area and also in the autumn for the birds farther north, possibly due to the northward movement and increase in strength of the southeast trade wind in the winter. Individual birds’ apparently erratic breeding behaviour may help them to avoid predators and parasites.","PeriodicalId":34898,"journal":{"name":"Atoll Research Bulletin","volume":"9 4 1","pages":"237-263"},"PeriodicalIF":0.0,"publicationDate":"2005-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70937829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Dinoflagellate, Diversity and abundance in two Belizean Coral Reef-Mangrove Lagoons: A test of Margalefs Mandala","authors":"M. A. Faust, R. Litaker, M. Vandersea, S. Kibler, P. Tester","doi":"10.5479/SI.00775630.534.105","DOIUrl":"https://doi.org/10.5479/SI.00775630.534.105","url":null,"abstract":"Dinoflagellates are frequently abundant in the coral-reef mangrove lagoons off the coast of Belize. Margalef predicted that marine environments with low turbulence and high nutrient inputs would favor dinoflagellates. A long-term study of coral-reef mangrove embayment cays of Belize, including this study, has shown that these systems contain abundant dinoflagellate species. Consistent with Margalef’s prediction, these habitats are protected from wind mixing, show a high degree of stratification, and have restricted water exchange with surrounding oligotrophic waters of the open barrier-reef system. This limited water exchange favors retention of dinoflagellate cells and the trapping of nutrient rich organic material that is rapidly recycled providing a relatively high-nutrient environment. Species-specific blooms are a common feature of these systems. In the study, the ecology and diversity of dinoflagellate species from two nutrient-enriched habitats, Douglas Cay and The Lair at Twin Cay, were examined in detail. A comparison of the species composition from both sites showed that Douglas Cay contained coastal planktonic and offshore oceanic dinoflagellates while The Lair at Twin Cay contained mainly benthic dinoflagellates. A total of 19 bloom-forming species were observed in these systems during three two-week studies. The morphology of eight of these bloom-forming species is illustrated in Scanning Electron Microscopy (SEM) photographs. These include Bysmatrum caponii, Dinophysis caudata, Gonyaulax grindleyi, Peridinium quinquecorne, Gonyaulax polygramma, Gonyaulax spinifera, Lingulodinium polyedrum, and Pyrodinium bahamense var. bahamense. Approximately half of the bloom-forming dinoflagellates are known toxin producers. The congruence between Margalef’s prediction and the distribution of dinoflagellates in these naturally eutrophic systems suggests that increased nutrient inputs in oligotrohic portions of the Caribbean will favor a shift in species dominance toward dinoflagellate species. The effect will be most pronounced in bays or other regions where turbulence is likely to be reduced. This species shift may have consequences for food web dynamics and the prevalence of dinoflagellate toxins in the food chain. _______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 1 Department of Botany, National Museum of Natural History, Smithsonian Institution, Washington D.C., 20560. 2 NOS/NOAA, Center for Coastal Fisheries Habitat Research, 101 Pivers Island Road, Beaufort, North Carolina, 28516.
