by Hannah Calich, RJD Intern Elevated carbon dioxide (CO2) levels have been shown to not only impact the health of coral reefs, but the health of coral reef associated fish as well. Coral-dwelling gobies are among the most habitat-specialized fish on coral reefs. Since these fish are rarely found outside of their preferred habitat they […]
by Laurel Zaima, RJD Intern The buildup of carbon dioxide in the ecosystem impacts more than just the earth’s climate. One of the most commonly known consequences of the surplus release of carbon dioxide into the atmosphere is global warming; however, changes in the ocean chemistry is also associated with the increased emission of CO2. […]
by Jessica Ann Wingar, RJD Intern Coral reefs are a very important part of the ecosystem, and over the years, the condition of the world’s coral reefs has changed drastically; this condition has not changed for the better. There are many resources that coral reefs provide to the world. Some of these include tourism value […]
by Hannah Armstrong, RJD Intern More than 25% of the world’s fishery populations are considered overexploited or depleted, and 40% are heavily to fully exploited (Dayton PK, Sala E, Tegner MJ, Thrush S). In fact, some marine organisms have been driven extinct by human activity, while others remain close to extinction (Dayton PK, Sala E, […]
by Emily Nelson, RJD Intern Sperm whales have been recorded diving to depths well over 2,000 meters. Elephant seals have recorded dives lasting over 2 hours. Humans, on average, can hold their breath underwater for less than 30 seconds. How is it that marine mammals spend such long periods of time underwater, diving to incredible […]
by Fiona Graham, RJD Graduate Student and Intern Utilizing film as a media to communicate science can be a powerful way to quickly reach large numbers of the general public in a user friendly way. Whether it’s newly published scientific research, or you’re trying to promote scientific awareness for conservation purposes, choosing to create a […]
by Frank Gibson, SRC media intern When most people think of shark week, the first image that comes to their head is one of a Great White Shark soaring into the air in pursuit of seals. What most people may not know is that the man responsible for these incredible images is Chris Fallows. Chris […]
by Fiona Graham, RJD Graduate Student and Intern Bycatch, the incidental catch of non-target species, tends to be high when using non-discriminatory fishing methods, such as longlining. Longline fisheries, such as that of Costa Rica, generally target mahi mahi and silky sharks, however data collected by an observer program shows that a large percentage of […]
by Laurel Zaima, RJD Intern The endangerment and extinction of many plant and animal species is often due to a direct anthropogenic impact on the environment. If humans cause the endangerment of a species, humans should be held responsible for recovery of that species. Unfortunately, this is the case for the incredibly unique elasmobranch, the […]
by Beau Marsh, RJD Intern Fishmeal and fish-oil are global commodities produced for both animal and human consumption. These products are manufactured from whole fish catches, as well as the by-products of fish processed for human consumption. Fishmeal and fish-oil are utilized for livestock and aquaculture feeds, and fish-oil is being increasingly sought after by […]
