    7 DAY & 7 NIGHT GREAT BARRIER REEF ITINERARY PORT DOUGLAS | GREAT BARRIER REEF | COOKTOWN | LIZARD ISLAND PORT DOUGLAS Port Douglas is a town on the Coral Sea in the tropical far north of Queensland, Australia. Located a scenic 50 minute drive north of Cairns International airport, It's known for its luxury beach resorts and as a base for visits to both the Great Barrier Reef, the world's largest reef system, and Daintree National Park, home to biodiverse rainforest. In town, Macrossan Street is lined with boutique shops and restaurants. Curving south is popular Four Mile Beach. THE RIBBON REEFS - GREAT BARRIER REEF - Characteristically no wider than 450m, the Ribbon Reefs are part of the Great Barrier Reef Marina Park and are covered in colorful corals that attract a plethora of reef life big and small, with sandy gullies separating them, themselves containing interesting critters. The Ribbons reef host several of Australia’s most spectacular dive sites, as well as arguably the most prolific Black Marlin fishing in the world at certain times of year -with general fishing topping the list also. LIZARD ISLAND Lizard Island hosts Australia’s northernmost island resort. It is located 150 miles north of Cairns and 57 miles north east off the coast from Cooktown. Lizard Island is an absolute tropical paradise, a haven of isolation, gratification and relaxation. Accessible by boat and small aircraft, this tropical haven is a bucket list destination. Prominent dives spots on the Ribbon Reefs are generally quite shallow, with bommies coming up to as high as 5 metres below the surface from a sandy bottom that is between 15-20 metres below the surface.

  • WDFW Washington State Status Report for the Bald Eagle
    STATE OF WASHINGTON October 2001 WashingtonWashington StateState StatusStatus ReportReport forfor thethe BaldBald EagleEagle by Derek W. Stinson, James W. Watson and Kelly R. McAllister Washington Department of FISH AND WILDLIFE Wildlife Program WDFW 759 The Washington Department of Fish and Wildlife maintains a list of endangered, threatened and sensitive species (Washington Administrative Codes 232-12-014 and 232-12-011, Appendix I). In 1990, the Washington Fish and Wildlife Commission adopted listing procedures developed by a group of citizens, interest groups, and state and federal agencies (Washington Administrative Code 232-12-297, Appendix I). The procedures include how species listing will be initiated, criteria for listing and delisting, public review and recovery and management of listed species. The first step in the process is to develop a preliminary species status report. The report includes a review of information relevant to the species’ status in Washington and addresses factors affecting its status including, but not limited to: historic, current, and future species population trends, natural history including ecological relationships, historic and current habitat trends, population demographics and their relationship to long term sustainability, and historic and current species management activities. The procedures then provide for a 90-day public review opportunity for interested parties to submit new scientific data relevant to the draft status report and classification recommendation. During the 90-day review period, the Department held three public meetings to take comments and answer questions. The Department has now completed the final status report, listing recommendation and State Environmental Policy Act findings for presentation to the Washington Fish and Wildlife Commission.

  • Coral Reef Education and Australian High School Students
    CORAL REEF EDUCATION AND AUSTRALIAN HIGH SCHOOL STUDENTS by Carl M. Stepath, MEd PhD Candidate: School of Education, and School of Tropical Environment Studies & Geography; James Cook University, Cairns, Qld 4878, Australia, [email protected] In proceedings of the Marine Education Society of Australasia 2004 Conference, Noosa, Queensland, October 2-3, 2004. Keywords: tropical marine education, environmental and marine experiential education, environmental awareness and attitudes, ecological agency, coral reef education Abstract: This paper reports on a PhD research project investigating marine education in coral reef environments along the Queensland coast. The study explored relationships between awareness, attitudes and ecological skills of high school students who were trained in coral reef ecology and monitoring in offshore sites along the Great Barrier Reef in 2002 and 2003. The research investigated the question of whether experiential marine education can change the reported environmental knowledge, attitudes and ecological agency of student participants. Some key data outcomes are presented and implications for effective marine education strategies discussed. Introduction Educational programs that focus on humans and their relationship to coral reefs are becoming necessary, as reef structures along the Queensland coast come under mounting ecological pressure (GBRMPA, 2003; Hughes et al., 2003; Talbot, 1995). Marine education has been defined by Roseanne Fortner (1991) as that part of the total educational process that enables people to develop sensitivity to and a general understanding of the role of the seas in human affairs and the impact of society on the marine and aquatic environments. Improving pedagogical techniques concerning aquatic environments is valuable since continuing intensification of human activity near coastline areas adversely affects marine and coastal ecosystems worldwide (NOAA, 1998).

  • (<I>Opsanus Beta</I>) Sonic Muscle Enzyme Activities
    BULLETIN OF MARINE SCIENCE, 45(1): 68-75,1989 SCALING AND SEX-RELATED DIFFERENCES IN TOADFISH (OPSANUS BETA) SONIC MUSCLE ENZYME ACTIVITIES Patrick J. Walsh, Cindy Bedolla and Thomas P. Mommsen ABSTRACT Male toadfishes (genus Opsanus) use a sonic muscle on the swim bladder to produce a mating call-the boatwhistle-for extended periods during the mating season. Previously, we noted significant differences in sonic muscle mass and activities of metabolic enzymes of the sonic muscles between male and female gulf toadfish, Opsanus beta, of a limited size range (12-130 grams). Notably, males had larger sonic muscles and elevated aerobic capacity, as indicated by higher mass-specific activities of citrate synthase (CS) and malate dehydrogenase (MDH). The present study examined the patterns of sonic muscle mass and activities of these enzymes (and lactate dehydrogenase) in sonic muscle and skeletal muscle as a function of a larger range of body size (7-400 grams) in an effort to determine the point of growth and development that these mate-female differences occur, and to shed light on the possible functional significances of these differences. Sonic muscle mass differences were apparent in the smallest toadfish, and identical rates of increase in sonic muscle mass in males and females maintained these differences throughout the size range examined. In contrast, mass-specific CS and MDH activities were similar in smaller toadfish and began to diverge when fish were about 2S g, While mass-specific MDH activity increased at different rates in males and females, mass-specific CS activity increased in males and decreased in females.

Important components of the jetty fauna during its initial stages of development were: (a) original residents that exhibit some attraction to reef habitats, including some sand-beach inhabitants, several pelagic species, and a few ubiquitous estuarine species; and (b) reef fishes originating from permanent populations on offshore reefs.

The series is also available on CD-Rom. CCC fish and coral species lists 1. INTRODUCTION Between 1986 and 1998, Coral Cay Conservation (CCC) provided data and technical assistance to the Belize Department of Fisheries, Coastal Zone Management Unit and Coastal Zone Management Project under the remit of a Memorandum of Understanding. This work has provided data for seven proposed or established marine protected areas at South Water Cay, Bacalar Chico, Sapodilla Cays, Snake Cays, Laughing Bird Cay, Caye Caulker and Turneffe Atoll (Figure 1). These projects have generally provided habitat maps, the associated databases and management recommendations to assist reserve planning. In addition to the data collection, training, capacity building and environmental education undertaken by CCC, the expeditions have also provided opportunities for compiling presence / absence species lists of fish and corals in the different project areas.
