Outbreak of Acropora white syndrome following a mild bleaching event at Palmyra Atoll, Northern Line Islands, Central Pacific
No abstract available.AuthorsG.J. Williams, I.S. Knapp, Thierry M. Work, E.J. ConklinInter-specific coral chimerism: Genetically distinct multicellular structures associated with tissue loss in Montipora capitata
Montipora white syndrome (MWS) results in tissue-loss that is often lethal to Montipora capitata, a major reef building coral that is abundant and dominant in the Hawai'ian Archipelago. Within some MWS-affected colonies in Kane'ohe Bay, Oahu, Hawai'i, we saw unusual motile multicellular structures within gastrovascular canals (hereafter referred to as invasive gastrovascular multicellular structurAuthorsThierry M. Work, Zac H. Forsman, Zoltan Szabo, Teresa D. Lewis, Greta S. Aeby, Robert J. ToonenPatterns of coral disease across the Hawaiian Archipelago: Relating disease to environment
In Hawaii, coral reefs occur across a gradient of biological (host abundance), climatic (sea surface temperature anomalies) and anthropogenic conditions from the human-impacted reefs of the main Hawaiian Islands (MHI) to the pristine reefs of the northwestern Hawaiian Islands (NWHI). Coral disease surveys were conducted at 142 sites from across the Archipelago and disease patterns examined. TwelveAuthorsG.S. Aeby, G.J. Williams, E.C. Franklin, J. Kenyon, E.F. Cox, S. Coles, Thierry M. WorkGlobal research priorities for sea turtles: Informing management and conservation in the 21st century
Over the past 3 decades, the status of sea turtles and the need for their protection to aid population recovery have increasingly captured the interest of government agencies, non-governmental organisations (NGOs) and the general public worldwide. This interest has been matched by increased research attention, focusing on a wide variety of topics relating to sea turtle biology and ecology, togetheAuthorsM. Hamann, M.H. Godfrey, J.A.

Work, N. Zbinden, B.J. GodleyMicroparasite ecology and health status of common bluestriped snapper Lutjanus kasmira from the Pacific Islands
Common bluestriped snappers Lutjanus kasmira were intentionally introduced into Hawaii from the South Pacific in the 1950s and have become well established throughout the archipelago. We examined health, prevalence and infection intensity of 2 microparasites, coccidia and epitheliocystis-like organisms (ELO), in L. kasmira from their introduced and native range including the islands where translocAuthorsThierry M. Work, M. Vignon, G.S. AebyRelationship between fibropapillomatosis and environmental quality: A case study with Chelonia mydas off Brazil
We documented the presence of fibropapillomatosis (FP), a debilitating tumor-forming disease, in marine turtles in Espírito Santo Bay (Brazil) from March 2007 to April 2008, and assessed the value of a specific environmental index for predicting the prevalence of FP. Turtles were captured monthly with entanglement nets and scored for presence and severity of FP. For the assessment of habitat qualiAuthorsRobson G. Santos, Agnaldo Silva Martins, E.

Sleeman, James WintonAvian botulism: a case study in translocated endangered Laysan ducks (Anas laysanensis) on Midway Atoll
Laysan Ducks are endemic to the Hawaiian archipelago and are one of the world’s most endangered waterfowl. For 150 yr, Laysan Ducks were restricted to an estimated 4 km2 of land on Laysan Island in the northwestern Hawaiian Islands. In 2004 and 2005, 42 Laysan Ducks were translocated to Midway Atoll, and the population increased to approximately 200 by 2007. In August 2008, mortality due to botuliAuthorsThierry M. Work, John L.

We examined the gross and microscopic pathology and distribution of sea turtles that were landed as bycatch from the Hawaii, USA–based pelagic longline fishery and known to be forced submerged. Olive ridley turtles (Lepidochelys olivacea) composed the majority of animals examined, and hook-induced perforation of the esophagus was the most common gross lesion followed by perforation of oral structuAuthorsThierry M.

We documented the microscopic morphology of tissue healing in Montipora capitata. Fragments from two healthy coral colonies were traumatized by scraping tissue and skeleton and monitored in flow-through seawater tables every 2-4. days for 40. days for gross and cellular changes. Grossly, corals appeared healed and repigmented by Day 40. Histologically, traumatized issues were undistinguishable froAuthorsThierry M. Work, Greta S.

Tropical coral reefs harbour a reservoir of enormous biodiversity that is increasingly threatened by direct human activities and indirect global climate shifts. Emerging coral diseases are one serious threat implicated in extensive reef deterioration through disruption of the integrity of the coral holobiont – a complex symbiosis between the coral animal, endobiotic alga and an array of microorganAuthorsDavid G.
