An Introduction to Marine Ecology (eBook, PDF)

Based on a wealth of international teaching expertise, An Introduction to Marine Ecology is written to be the basis for an entire undergraduate course in marine biology or ecology. It covers the trophic, environmental and competitive interactions of marine organisms, and the effects of these on the productivity, dynamics and structure of marine systems.

The strength of the book lies in its discussion of core topics which remains at the heart of the majority of courses in the subject, despite an increasing emphasis on more applied aspects. Completely revised and updated with a twofold increase in the number of illustrations.

Adopts a more applied approach in keeping with current teaching. New chapters on fisheries, the marine ecosystem, conservation and pollution.

Based on a proven and successful course structure. Free Access.

Marine conservation

These are used to track movements of usually large, migratory marine animals. A PSAT is an archival tag or data logger that is equipped with a means to transmit the collected data via satellite.

Though the data are physically stored on the tag, its major advantage is that it does not have to be physically retrieved like an archival tag for the data to be available, making it a viable independent tool for animal behavior studies. These tags have been used to track movements of ocean sunfish , [14] marlin , blue sharks , bluefin tuna , swordfish and sea turtles.

Location, depth, temperature, and body movement data are used to answer questions about migratory patterns, seasonal feeding movements, daily habits, and survival after catch and release.

Many sea turtles are accidentally captured, injured or killed by fishing. A TED is a series of bars that is placed at the top or bottom of a trawl net, fitting the bars into the "neck" of the shrimp trawl and acting as a filter to ensure that only small animals may pass through.

The shrimp will be caught but larger animals such as marine turtles that become caught by the trawler will be rejected by the filter function of the bars. However, they do so without behavioral changes, and address the symptoms but not the cause of the declines. Examples of halfway technologies include hatcheries and fish ladders.

In , the Scottish Parliament enacted new legislation for the protection of marine life with the Marine Scotland Act Its provisions include marine planning, marine licensing, marine conservation, seal conservation, and enforcement. Since , united nations introduce vulnerable marine ecosystem concept for the management of deep-sea fisheries in the areas beyond national jurisdiction.

Zoox United Kingdom is an example of an organization that provides both marine conservation training and professional career development to volunteers who are also working on marine conservation projects such as Green Fins.

Extinct and endangered species[ edit ] Marine mammals[ edit ] Baleen whales were predominantly hunted from through the mids, and were nearing extinction when a global ban on commercial whaling was put into effect in by the IWC International Whaling Convention.

The Hawaiian and Mediterranean monk seals are considered to be one of the most endangered marine mammals on the planet, according to the NOAA. Over half the population has disappeared since , leaving left in Population decline in ocean basins is indicated through data collected by the MTSG that analyzes abundance and historical information on the species.

This data examined the global population of green turtles at 32 nesting sites, and determined that over the last — years there has been a 48—65 percent decrease in the number of mature nesting females. In the early s only 5, individuals were left, and between and , Kemp's Ridley Turtles nested annually. In , the World Wildlife Fund and National Geographic Magazine named the Kemp's ridley the most endangered sea turtle in the world, with females nesting annually.

The Pacific bluefin tuna is targeted by the fishing industry mainly for its use in sushi. According to the ISC assessment, 90 percent of the Pacific bluefin tuna caught are juveniles that have not reproduced. An Environmental Agency officer, Andy Don, who has been researching eels for the past 20 years, said, "There is no doubt that there is a crisis.

People have been reporting catching a kilo of glass eels this year when they would expect to catch 40 kilos. We have got to do something. It reproduces asexually , which limits its ability to populate and colonize habitats.

Data on this species is limited, but it is known that since the s there has been a 50 percent decrease in abundance.Moving into productive shelf waters and oligotrophic subtropical gyres, upper ocean processes will be considered in terms of the controls and limits to phytoplankton primary production at regional and global scales. This series was planned, organized, contributed to and edited by Otto Kinne.

Review my other posts. I have always been a very creative person and find it relaxing to indulge in trap shooting. I do enjoy exploring ePub and PDF books beautifully .
