Marine Conservation
MarineBio is deeply committed to the conservation of the ocean and its marine life. We encourage you to get involved in marine conservation, whether you spend a weekend cleaning up a beach or writing your elected representatives to support environmental legislation. Unfortunately, the health of the ocean and marine life are so often taken for granted, perhaps because the ocean seems so big that it must be invincible.... But, mainly due to our increasing numbers and wasteful practices, the ocean appears to be as vulnerable to harm by human activities as any other environmental realm—and maybe even more so based on the severity and scale of the threats discussed below.
101+ Ways to Make a Difference
No matter what your economic standing, you can help save/restore/protect the environment and save money at the same time. You the consumer drive the market; products are made because you buy them. If you buy products that are better for the environment it will become profitable for companies to respond to the demand for environmentally-friendly products. It really is that simple »

A Sea Ethic
Launching a Sea Ethic was Dr. Carl Safina's call for a stronger sense of right and wrong when it comes to the way we treat the ocean and marine life. It was a proposition for all to treat the ocean and its creatures with the same conservation ethic as many have for land and its creatures. It simply means that we should manage the sea's resources sustainably, that we should take strong measures to avoid destruction of habitats, species depletion, pollution, and other threats faced by the ocean that often goes unnoticed because the scars are not as evident as they are on land.
Truly magnificent—Safina has done as much as anyone save Cousteau to change our relationship with the aquatic world. - Bill McKibben, The Boston Globe
MarineBio also highly recommends Dr. Safina's books, which describe many of our ocean's problems in ways that urges all of us to find equitable solutions. These books read like entertaining travel narratives, yet they powerfully convey important messages in an objective, eloquent, and compelling manner. » more...
Marine Conservation Biology: The Science of Maintaining the Sea's Biodiversity
Humans are terrestrial animals, and our capacity to see and understand the importance and vulnerability of life in the sea has trailed our growing ability to harm it. While conservation biologists are working to address environmental problems humans have created on land, loss of marine biodiversity, including extinctions and habitat degradation, has received much less attention. At the same time, marine sciences such as oceanography and fisheries biology have largely ignored issues of conservation.
Marine Conservation Biology brings together for the first time in a single volume leading experts from around the world to apply the lessons and thinking of conservation biology to marine issues. Contributors including James M. Acheson, Louis W. Botsford, James T. Carlton, Kristina Gjerde, Selina S. Heppell, Ransom A. Myers, Julia K. Parrish, Stephen R. Palumbi, and Daniel Pauly offer penetrating insights on the nature of marine biodiversity, what threatens it, and what humans can and must do to recover the biological integrity of the world's estuaries, coastal seas, and the ocean.
Sections examine: distinctive aspects of marine populations and ecosystems; threats to marine biological diversity, singly and in combination; place-based management of marine ecosystems; the often-neglected human dimensions of marine conservation.
Marine Conservation Biology breaks new ground by creating the conceptual framework for the new field of marine conservation biology—the science of protecting, recovering, and sustainably using the living sea. It synthesizes the latest knowledge and ideas from leading thinkers in disciplines ranging from larval biology to sociology, making it a must-read for research and teaching faculty, postdoctoral fellows, and graduate and advanced undergraduate students.
Even as humankind spends billions of dollars in the hope of detecting the faintest echoes of life on Mars, the only place in the universe where we know that life exists has rapidly been losing its distinguishing characteristic, its biological diversity, the diversity of genes, species, and ecosystems. - Heywood 1995; Norse and McManus 1980; Norse et al. 1986; Office of Technology assessment 1987; Wilson 1988

Sustainable Fisheries
70% of the earth's commercially targeted fish species have been overfished to the point where their stocks are in grave danger of being depleted. Fish harvests have quadrupled since the 1950s and the competition for marketable catches has increased to the point where competition is driving governments to subsidize fishing vessels. How can this problem be resolved and who is working to resolve it? Can the fishing industry and conservation concerns reach consensus to find a sustainable solution?

» The Empty Ocean: Plundering the World's Marine Life
Pollution is a worldwide problem, and our fish comes from around the world, said Kate Mahaffey, toxins expert at the US Environmental Protection Agency. No one is immune. With contaminants in fish, she warned, there is a very narrow range between levels with no effects, subtle effects and severe effects.
Governments tend to be more preoccupied with protecting national quotas against efforts to curb catches and preserve fish stocks, and are reluctant to spend the large sums necessary to test adequate samples in open waters.
Even when data is convincing, experts say, action falls short. Despite the clear risk from such long-lived large fish as swordfish, shark and types of tuna, public warnings are often not spelled out.
Smaller fish rich in fat can also be hazardous, although they are seldom flagged. Norwegian researchers say Baltic Sea herring carry up to 10 times as much contamination as salmon. A growing trend toward fish-farming adds new dangers, according to the specialists. » more...
Marine Biodiversity
Pulitzer prize winning biologist Dr. E. O. Wilson, widely known as the father of biodiversity, said that the loss of biodiversity is the "folly for which our descendants are least likely to forgive us." What will our children say when they discover that generations before them destroyed what can never be replaced? Biological diversity in the ocean is much greater than biodiversity on land—a staggering concept, considering the abundance and variety of life on land—yet much more is known about terrestrial biodiversity. The ocean is not as accessible which accounts for part of the problem, but in addition, only in recent years has interest in marine biodiversity increased, likely due to the critically low populations of several key marine species. Threats to biological diversity in the ocean abound as commercially targeted species are overfished and fishing methods remain indiscriminate against non-targeted species. The use of cyanide and dynamite to harvest reef fish is threatening those communities at an alarming rate. Find out why preserving biodiversity is important and what is being done about it.
Today's mass extinctions are unlike mass extinctions in the geologic past, in which tens of thousands of species died out following massive catastrophes such as asteroid collisions with the Earth and dramatic temperature changes—today's extinctions have a human face. - Richard B. Primack, Boston University, Essentials of Conservation Biology, p. 3, 2002
» 15,589 Species at Risk of Extinction
It is clear that the situation facing our species is serious and getting worse. We must refocus and rethink the way in which society must respond to this global threat, says Achim Steiner, IUCN's Director General. While most threats to biodiversity are human-driven, human actions alone can prevent many species from becoming extinct.

» Planetary Biodiversity Inventories - Mission to an (almost) unknown planet (NSF Fact Sheet) - What kinds of living things exist? Where do they live? How are they related? These are simple questions, but have few answers. Were life to be discovered today on another planet, resources would quickly be mustered to inventory its diversity. Yet we remain ignorant about most of the diversity of life on Earth. To date, only 5 to 15 percent of all life on our home base has been discovered and described.
» Nova Scotia Grey Seal Hunt, 2004 - How, exactly, to Kill an Ocean, by Debbie MacKenzie
The sudden decline in the Nova Scotia offshore harbour seal population, and their apparent increasing presence near shore, echoes recent shifts in marine mammal populations that have been observed elsewhere in the world. The Steller sea lion population on Alaska's offshore Aleutian Islands has fallen away rapidly in recent years, also showing signs of “nutritional stress,” while those living near the mainland still maintain their numbers. South African seals no longer breed at their traditional offshore island rookeries, but are increasingly colonizing the mainland and running into conflict with terrestrial predators. Mass starvation of seal pups in South Africa occurs now on a regular basis. The Hawaiian monk seal, inhabiting waters around the small outer Hawaiian islands, is disappearing due to starvation…and starving sea lions now regularly inundate marinas and estuaries in California... - Debbie MacKenzie
Global Warming/Climate Change
The debate is finally over (and actually has been since at least 2001). Global warming is happening and is primarily caused by our fossil fuel emissions unnaturally increasing greenhouse gases (mainly CO2) in the earth's atmosphere. What impact does global warming have on the ocean? Two tangible effects are the sea level rise from the melting of ice sheets and glaciers at record levels and the overall acidification of the ocean. If this trend continues, sea level rise will impact the densely populated coastal areas all over our planet, and ocean acidification has worldwide possible impacts that include a complete breakdown of most marine food webs. What are the current theories on global warming and what is being done to reverse the trend? » more...

» By 2050 Warming to Doom Million Species, Study Says - By 2050, rising temperatures exacerbated by human-induced belches of carbon dioxide and other greenhouse gases could send more than a million of Earth's land-dwelling plants and animals down the road to extinction, according to a recent study.
Threatened and Endangered Species
Until recently, humankind seemed to view the ocean as a source of infinite resources. Its apparent vast size and unlimited depth made the ocean appear invulnerable to overexploitation. The truth is that the populations of many species are decreasing at an unsustainable rate, and the number of species listed as endangered from marine life families such as whales, dolphins, manatees and dugongs, salmon, seabirds, sea turtles, and sharks to name a few, are on the rise. Although it is difficult to perceive because marine life is not as visible as animals on land, it is equally if not more vulnerable to problems such as habitat destruction and overexploitation. » more...
Habitat Conservation
Everyone knows that the northern spotted owl is threatened because of destruction to the forests of the Pacific Northwest - but what will happen to the Pacific seahorse if its habitat continues to decline? Due to the lack of a strong public sea ethic, marine life doesn't appear on the conservation radar screen as much as its terrestrial counterparts, but ocean habitats are in decline as well, and therefore the creatures they support are too (which in turn support us). Most marine habitat destruction is caused by pollution, commercial fishing equipment, coastal development, and other human activity. Much of it can be avoided with simple measures.

Alien Species
The introduction of non-native species to an ecosystem is one of the major causes of decreased biodiversity. Termed alien species, they are also known as exotic, introduced, non-indigenous, or invasive species. As the names imply, these species do not belong to ecosystems in which they are either intentionally or unintentionally placed. They tend to disrupt the ecosystem's balance by multiplying rapidly. These species are often plants, fishes, mollusks, crustaceans, algae, bacteria or viruses. » more...
Ocean Pollution
Although the ocean covers over two-thirds of the surface of the Earth, it is surprisingly vulnerable to human influences such as overfishing, pollution from run-off, and dumping of waste from human activity. This kind of pollution can have serious economic and health impacts by killing marine life and damaging habitats and ecosystems. Toxins from pesticides, fertilizers, and other chemicals used on farms contaminate nearby rivers that flow into the ocean, which can cause extensive loss of marine life in bays and estuaries, leading to the creation of dead zones. The dumping of industrial, nuclear and other waste into oceans was legal until the early 1970s when it became regulated; however dumping still occurs illegally everywhere. » more...
Ocean Resources
The ocean is one of Earth's most valuable natural resources. It provides food in the form of fish and shellfish—about 200 billion pounds are caught each year. It's used for transportation—both travel and shipping. It provides a treasured source of recreation for humans. It is mined for minerals (salt, sand, gravel, and some manganese, copper, nickel, iron and cobalt can be found in the deep sea) and drilled for crude oil. The ocean plays a critical role in removing carbon from the atmosphere and providing oxygen. It regulates Earth's climate. The ocean is an increasingly important source of biomedical organisms with enormous potential for fighting disease. These are just a few examples of the importance of the ocean to life on land. Explore them in greater detail to understand why we must keep the ocean healthy for future generations... » more...
Sustainable Ecotourism
Sustainable tourism, also known as ecotourism, is defined as leisure travel that provides tourists with an educational and adventurous experience visiting complex and fascinating ecosystems and their associated cultures and traditions. The concept of ecotourism began in the late 1980s and increased in popularity in 2002 during the United Nations "International Year of Ecotourism." According to environmental and other organizations, ecotourism should have a minimal impact on both the environment and the culture. Ecotourism should inform tourists about what's needed to sustain the environment they're visiting, and should also help local populations understand the importance and value of their home. » more...
Marine Conservation Organizations
MarineBio has compiled an evolving list of conservation organizations working on a variety of issues related to marine conservation. We encourage you to read through them and support the organizations doing work in areas that you feel strongly about. In our increasingly conservative economic climate, funding by private foundations and institutions is scarce.

50 Ways to Save the Ocean
The oceans, and the challenges they face, are so vast that it's easy to feel powerless to protect them. 50 Ways to Save the Ocean, written by veteran environmental journalist David Helvarg, focuses on practical, easily-implemented actions everyone can take to protect and conserve this vital resource. Well-researched, personal, and sometimes whimsical, the book addresses daily choices that affect the ocean's health: what fish should and should not be eaten; how and where to vacation; storm drains and driveway run-off; protecting local water tables; proper diving, surfing, and tide pool etiquette; and supporting local marine education. Helvarg also looks at what can be done to stir the waters of seemingly daunting issues such as toxic pollutant runoff; protecting wetlands and sanctuaries; keeping oil rigs off shore; saving reef environments; and replenishing fish reserves.
Essays on Wildlife Conservation
MarineBio is proud to present Essays on Wildlife Conservation written and edited by Dr. Peter Moyle, et al. for an introductory course on wildlife conservation taught at the University of California, Davis. The essays were written for students who are not only biology majors and are broad in scope. These chapters provide an introduction to the history of wildlife in North America, biodiversity, natural selection, conservation biology, ecology, conservation legislation, alien species, wildlife and pollution, and things we can all do to save wildlife. We think you will find that they are not only fascinating to read but also very useful toward understanding the myriad of issues concerning conservation efforts today. » more...

Is The World Ready To Accept Responsibility And Take The Action Needed To Protect Our Marine Resources?
Man has become by far the greatest predator of all time. As populations mount and land-grown food supplies are unable to feed the growing numbers of the hungry, man is turning more and more to the sea for his food. On land man has slowly learned to conserve the soil lest it stop producing crops. But on the ocean, man is a hunter only. He takes but returns little. If the bounty of the sea is not to be exhausted, man must learn to farm it as he farms the land, by sowing as well as reaping. - The Ocean World of Jacques Cousteau, 1975
The more clearly we can focus our attention on the wonders and realities of the universe about us, the less taste we shall have for destruction. Rachel Carson
He who is cruel to animals becomes hard also in his dealings with men. We can judge the heart of a man by his treatment of animals. - Immanuel Kant
We need another and a wiser and perhaps a more mystical concept of animals. Remote from universal nature, and living by complicated artifice, man in civilization surveys the creature through the glass of his knowledge and sees thereby a feather magnified and the whole image in distortion. We patronize them for their incompleteness, for their tragic fate of having taken form so far below ourselves. And therein we err, and greatly err. For the animal shall not be measured by man. In a world older and more complete than ours they move finished and complete, gifted with extensions of the senses we have lost or never attained, living by voices we shall never hear. They are not brethren, they are not underlings; they are other nations, caught with ourselves in the net of life and time, fellow prisoners of the splendor and travail of the earth. - Henry Beston, 1928

Sea Life News :: ScienceDailyFirst-of-its-kind study reveals surprising ecological effects of earthquake and tsunami
The reappearance of long-forgotten habitats and the resurgence of species unseen for years may not be among the expected effects of a natural disaster. Yet that's exactly what researchers have found on the sandy beaches of south central Chile, after an 8.8-magnitude earthquake and devastating tsunami in 2010. Their study also revealed a preview of the problems wrought by sea level rise -- a major symptom of climate change.
Old fish makes new splash: Coelacanth find rewrites history of the ancient fish

Marine food chain becomes clearer with new revelations about prey distribution
A new study has found that each step of the marine food chain is clearly controlled by the trophic level below it -- and the driving factor influencing that relationship is not the abundance of prey, but how that prey is distributed.
Impaired recovery of Atlantic cod: Forage fish or other factors?
Biologists suggest the delay in recovery of Atlantic cod on the eastern Scotian Shelf could be attributed to increased predation by grey seals or other governing factors and not the effect of forage fish as previously thought.
Global warming refuge discovered near at-risk Pacific island nation of Kiribati
Scientists predict ocean temperatures will rise in the equatorial Pacific by the end of the century, wreaking havoc on coral reef ecosystems. But a new study shows that climate change could cause ocean currents to operate in a way that mitigates warming near a handful of islands right on the equator.
Pacific islands on equator may become refuge for corals in a warming climate due to changes in ocean currents
Scientists have predicted that ocean temperatures will rise in the equatorial Pacific by the end of the century, wreaking havoc on coral reef ecosystems. But a new study shows that climate change could cause ocean currents to operate in a surprising way and mitigate the warming near a handful of islands right on the equator. As a result these Pacific islands may become isolated refuges for corals and fish.
Scientists provide first large-scale estimate of reef shark losses in the Pacific Ocean
First study to provide estimates of reef shark losses in the Pacific Ocean are sobering. Researchers noted the enormous detrimental effect that humans have on reef sharks.
Purple sea urchin metamorphosis controlled by histamine
Now that hay fever season has started, sufferers are well aware of the effect of histamines. However it is easy to forget that histamine is also a neurotransmitter involved in controlling memories, regulating sleep, and controlling secretion of gastric acid. New research shows that for the purple sea urchin histamine is also responsible for controlling metamorphosis from a free swimming larval form to the spiny adult living on the sea floor.
Smalleye pigmy sharks' bellies shine: They glow for camouflage
Smalleye pigmy sharks have an eye-catching party trick: Their bellies glow. However, instead of being a giveaway, biologists have shown that the fish's shiny undersides probably provide camouflage. They also discovered that the pigmy shark and another glowing fish, the lantern shark, regulate their glow using the similar mechanisms, although the pigmy shark is probably more closely related to their common ancient ancestor.
Eight species of wild fish have been detected in aquaculture feed
Researchers have for the first time analyzed a DNA fragment from commercial feed for aquarium cichlids, aquaculture of salmon and marine fish in aquariums. The results show that in order to manufacture this feed, eight species of high trophic level fish have been used, some of them coming directly from extractive fisheries.
Did bone ease acid for early land crawlers?
Scientists have proposed that the bony structures in the skin of many early four-legged creatures might have been there to relieve acid buildup in bodily fluids. Analysis of their anatomy suggests that as they ventured out of water, the animals would have had trouble getting rid of enough CO2 to prevent acid buildup.
Geophysicists employ novel method to identify sources of global sea level rise
As the Earth's climate warms, a melting ice sheet produces a distinct pattern of sea level change known as its sea level fingerprint. Now, geophysicists have found a way to identify the sea level fingerprint left by a particular ice sheet, and possibly enable a more precise estimate of its impact on global sea levels.
Fish larvae find the reef by orienting: The earlier the better
For the first time, a numerical study incorporates horizontal larval fish navigation skills into realistic 3D flow fields, creating a powerful tool that spells out how larvae use environmental cues to find their way back to the reef after being out on the open ocean. This model can be used for a wide variety of marine species.

Scientists have studied loggerhead turtles' re-adaptation to the environment. The results show that after a lengthy recovery in rehabilitation centers these animals display changes in behavior and may not adapt well to being free.
Deadly jellyfish weapons unraveled
Researchers have analyzed proteins of stinging cells in the hydra freshwater polyp. The results of their research reveal a complex mixture of toxic and structural proteins that can explain the extraordinary toxicity and biophysical properties of these unique cells. They also show how the energy for discharging the toxin can be stored in the stinging cells and released at extraordinary speed.

Cod has a key role in the whole Baltic Sea
A new investigation put in evidence the key role of cod as regulator of the whole Baltic Sea ecosystem. The study shows that when the cod population in the central Baltic increases, it spreads into larger areas and spills over into adjacent marginal systems where it usually does not occur, as for example the Gulf of Riga.
BP oil spill, two years later: Natural recovery far greater than expected
This Friday, April 20, will mark two years since the explosion aboard the Deepwater Horizon oil rig caused vast quantities of crude oil to flow into the Gulf of Mexico. But despite the size of the spill, "the natural recovery is far greater than what anybody hoped when it happened," said a professor of biology. "The fears of most people -- that there would be a catastrophic collapse of the ecosystem in the Gulf -- never materialized."
Understanding of hearing in baleen whales amplified
For decades, scientists have known that dolphins and other toothed whales have specialized fats associated with their jaws, which efficiently convey sound waves from the ocean to their ears. But until now, the hearing systems of their toothless grazing cousins, baleen whales, remained a mystery, largely because specimens to study are hard to get. Now, a new study has shown that some baleen whales also have fats leading to their ears.
