The Impact Of The Queensland Shark Control Program On Local Populations Of Threatened Shark Species, 1962-2014, Carolyn Pushaw
The Impact Of The Queensland Shark Control Program On Local Populations Of Threatened Shark Species, 1962-2014, Carolyn Pushaw
Independent Study Project (ISP) Collection
Since 1962, the Queensland government has employed a shark control program consisting of shark nets and drum lines off the coast of popular beaches. This program is intended to protect beachgoers from shark interactions by fishing down local shark populations, reasoning that the fewer “large sharks that are present, all things being equal, the less chance of an attack occurring” (McPhee, 2012). In the current study, trends in Queensland Shark Control Program (QSCP) catch between 1962-2014 are examined for select threatened shark species; namely, Carcharodon carcharias, Carcharias taurus, and Sphyrna spp. For all focus species, significant and consistent …
Frog Diversity And Population Trends In Andasibe, Madagascar, Ryan Herman Herman, Alexandra Ulin
Frog Diversity And Population Trends In Andasibe, Madagascar, Ryan Herman Herman, Alexandra Ulin
Independent Study Project (ISP) Collection
Facing immediate threats such as habitat loss, emerging infectious diseases, and climate change, the frog populations of the Madagascar rainforest, one of the richest amphibian diversity hotspots in the world, are an important focus for monitoring programs. This study focused on assessing the general diversity, key species population trends, and monitoring effectiveness of the Analamazaotra Forest Station’s amphibian community, a population of over forty species within Andasibe, Madagascar. Building on a long-term monitoring program that began in 2012, visual encounter surveys were conducted over a two-week period in November 2015 along the edge and within the interior of the forest …
Magnetic Island Marine Park Zones: Effects Of Fishing Restrictions On Predatory Reef Fish Populations, Casey Wilson
Magnetic Island Marine Park Zones: Effects Of Fishing Restrictions On Predatory Reef Fish Populations, Casey Wilson
Independent Study Project (ISP) Collection
Over the past several decades industrialized fishing practices have decimated fish stocks worldwide. Top-down trophic cascades have occurred within many marine ecosystems as top predators are removed. Numerous regions world wide are being designated as marine park “no-take” zones in order to aid in the recovery of these species and with the hope that surplus population will spillover into unprotected zones..
This study aimed to determine if there were significant differences in abundances of three major families of predatory reef fish (Serranidae, Lutjanidae, and Lethrinidae) between fringing reefs located in four bays of various zones around Magnetic Island, QLD. Data …
Non-Compliance In Marine Reserves: Measuring The Drivers Of Behavior Among Recreational Fishermen Within The Great Barrier Reef Marine Park, Nick Manning
Independent Study Project (ISP) Collection
The Great Barrier Reef Marine Park (GBRMP) provides outstanding ecological, cultural, social, and economic services to the number of communities that use it. Most of the park is regulated via a zoning system designed to protect its biodiversity and ensure the sustainable use of its resources (GBRMPA, 2004). Like any social institution, zoning regulations rely heavily on compliance in order to be effective. Recreational fishing on the GBRMP accounts for most of the noncompliance behavior associated with zoning (Arias and Sutton, 2013). Thus, understanding fishers compliance behavior is central to understanding how to best manage these areas. Using results from …
Fish Use Of Largely Unexplored Sub-Tidal Habitats In The Hinchinbrook Channel Estuary, Queensland, Alexandra Parisien
Fish Use Of Largely Unexplored Sub-Tidal Habitats In The Hinchinbrook Channel Estuary, Queensland, Alexandra Parisien
Independent Study Project (ISP) Collection
This study examines the use of sub-tidal open-bottom, rocky, and seagreass habitats by the Siganus genus (herbivores), Gerres genus (benthivores), and planktivores in the Hinchinbrook Channel Estuary in Queensland, Australia. The Hinchinbrook Channel Estuary, a tropical estuary cutting between Hinchinbrook Island and the Australian mainland, is surrounded primarily by mangroves. Its sub-tidal habitats are largely unexplored due to factors such as low visibility and the presence of estuarine crocodiles. In this study, I reviewed 699 underwater videos collected by James Cook University PhD candidate Michael Bradley in order to analyze feeding and movement behavior of pre-identified fish.
The results of …
Taming The Teesta: Exploring The Holistic Effects Of Hydroelectric Dam Development On The Teesta River Through Documentary Film, Taylor Graham
Taming The Teesta: Exploring The Holistic Effects Of Hydroelectric Dam Development On The Teesta River Through Documentary Film, Taylor Graham
Independent Study Project (ISP) Collection
Since time immemorial, the Lepcha people have called the Himalayan region that makes up the modern state of Sikkim their home and have held sacred the rivers, mountains, and forests that make up the biologically diverse region. Over the past two decades, India’s rapid development has generated a powerful thirst for electricity, and the country has increasingly looked to the cold, powerful rivers thundering from the Himalayas to supply that desired power. Hydroelectric projects have been proposed and implemented throughout the Himalayan region. Nowhere, however, are the dams as numerous or their effects as acutely felt as in India’s northwestern …
Marine Animalia Organism Diversity And Reef Condition On Two Reef Sites At Big Creek Beach And Boca Del Drago, Bocas Del Toro, Panamá, Bri Tiffany
Independent Study Project (ISP) Collection
Ocean acidification, climate change, overfishing, and coastal development are endangering coral reefs across the globe. In Bocas del Toro, Panamá, coral reefs are especially threatened by the rapid growth in tourism and the subsequent anthropogenic effects caused by an increased human presence. To evaluate reef condition in this area, a study comparing percent coverage of live and dead coral as well as the diversity of marine Animalia organisms was conducted at one reef site in Big Creek beach and one reef site in Boca del Drago, Isla Colón, Bocas del Toro. It was predicted that dead coral cover would be …
