Marine Invasive Species in the Galapagos Marine Reserve
Marine biological invasions have increased significantly in recent years due to global trade, transport and tourism. Invasions occur when species get transported from one region to another and establish themselves in the new habitat. These species compete for space and resources, displacing native …

Soft sediment ecology of Lough Hyne Marine Reserve - spatial and temporal patterns
… scales. Investigations took place at Lough Hyne Marine Reserve using a range of methods. Data on the sedimentation rates of organic and inorganic matter were collected at monthly intervals for one year at a number of sites around the Lough, by use of vertical midwater-column sediment traps. …

The effects of a marine reserve on galjoen (Dichistius capensis) at Cape Point, South Africa, and implications for the management of the recreational fishery
Marine protected areas (MPAs) are gaining credibility in the scientific community because of their duality as a conservation and fishery management tool, but sometimes the actual effects of an MPA fall short of the expected outcomes. Case-by-case studies are needed to understand what works and what …

Distributional relationships among subtidal algae, sea urchins and reef fish in northeastern New Zealand
… 1988 - 1993. The Cape Rodney to Okakari Point Marine Reserve was the site of many of these investigations. The patterns of abundance of large brown macroalgae and urchins down depth gradients over a wide geographic range were compared with those reported from earlier studies, and 3 major trends …

A marine systematic conservation plan for Rodrigues Island, Western Indian Ocean
… the local government of Rodrigues gazetted four marine reserves in the north of the island based on knowledge and insights from stakeholders, mainly from the fishing community. In order to verify the stakeholder-based design, a marine reserve network was designed using Marxan, a systematic …

Variation in parasitism of intertidal invertebrates, with a focus on trematodes on the southwest of Ireland
Parasites are ubiquitous in marine ecosystems, are sensitive to a range of environmental conditions, share characteristics of traditional bioindicators, and can be indicators of environmental stress. To investigate the role of environmental stressors on parasite communities, specifically …

The effects of an invasive species on the structure of native ecosystems
… the dominant barnacle species within Lough Hyne marine reserve and on artificial structures surveyed in south-west Ireland. Despite this dominance, native barnacle species continue to persist both in the marine reserve and on artificial structures of varying ages. The continuous production of …

The Ready Reserve Force: is it capable of performing its mission
This thesis examines the Ready Reserve Force (RRF) from a personnel manning and supply and logistic support perspective. The history of the RRF and a discussion of its current status are included. Specifically examined is the decline in the number of merchant mariners and in the number of available …

The rise and fall of the spiny lobster (Jasus edwardsii) in the Hauraki Gulf, northeastern New Zealand
… is subjected to intense fishing pressure. While marine reserves have long been shown to be effective in rebuilding lobster populations, declines inside reserves and in fished areas in the Hauraki Gulf, northeastern New Zealand, over the last two decades raise concerns about the plight of this …

Mapping Belizean bonefish, permit, and tarpon fisheries and their threats
… changes in a portion of the South Water Caye Marine Reserve (SWCMR) from 2001 to 2016. Professional sport fishing guides ranked gillnets as the most threatening activity to Belizean BPT stocks, and most guides reported that the quality of sport-fishing of BPT has declined over their career. …

Coastal Resource Use, Management, and Marine Protected Areas in the Philippines
… Luzon, Mindoro Occidental, and Mindoro Oriental, marine conservation perceptions and behaviors were evaluated. Coastal resource users were found to perceive resource problems such as a decline in fish and feel that management and conservation are the responsibility of the government. Barangays …

Environmental assessment, documentation and spatial modeling of heavy metal pollution along the Jordan Gulf of Aqaba using coral reefs as environmental indicator
… lowest metal concentrations were observed at the marine reserve, the least impacted site along the coast. The high enrichment of metal is attributed mainly to anthropogenic impacts. The natural inputs of the six metals studied in the Gulf of Aqaba are generally very low, due to the geographic …

The effects of salinity on the cutaneous microbiome and pathogen infection on the Pacific Tree frog (Pseudacris regilla) in Monterey Bay, California, USA
… dendrobatidis (Bd). The Moro Cojo Slough State Marine Reserve (MCSSMR) (California, USA) is known as an abundant breeding ground for endangered/threatened amphibian species. To test and expand the salt refuge hypothesis, I evaluated Bd prevalence and intensity and the cutaneous microbiome of the …

The importance of interaction strength for food web dynamics and ecosystem functioning
… approach, through experimentation at Lough Hyne marine reserve, in southwest Ireland. Complex communities were allowed to develop naturally in exclusion cages, with only the diversity of top trophic levels controlled. Species removals were carried out and the resulting changes to predator-prey …

Marine protected areas in the management of artisanal fisheries
… of effort by fishers in waters adjoining a marine protected area, and their impacts on the reserve’s ability to reduce the impacts of overfishing. The artisanal fisheries operating near Blue Bay Marine Park, Mauritius, provided case-study data for analysis. Two forms of spatial connectivity …

Adapting Small Unmanned Aerial Systems for Behavioral Research with Coastal Marine Mammals
<p>Marine mammals inhabit aquatic worlds where their subsurface behavior, cryptic surface profiles, and movements make them difficult to study. New tools are needed to study coastal marine mammals in a world increasing impacted by climate change related shifts in weather and animal distribution …

The Response of a Predatory Fish, Ophiodon elongatus, to a Marine Protected Area: Variation in Diet, Catch Rates, and Size Composition
<p>Marine Protected Areas (MPAs) are a management tool used to protect and sustain many ecologically and economically important fish species from overexploitation by recreational and commercial fishing. Lingcod (<em>Ophiodon elongatus</em>) and some of its prey species, such as rockfish …
