Marine film festival returns with a splash

This post contributed by Ashwin Bhandiwad, marine biologist and filmmaker When my colleague and good friend Austin Gallagher told me he was thinking of starting a film festival focused on science and conservation, I relished the opportunity. Austin and I are graduate students and share a passion for the marine environment. Like all graduate students, we have had many conversations about how our work is woefully underappreciated and...

Invasive lionfish: from aquarium to dinner plate

The red lionfish (Pterois volitans) has decorated fish tanks, and invaded Atlantic waters, for decades. While sightings along the East Coast started popping up as early as the mid-1980s, lionfish began to spread rapidly, occupying reefs in the Florida Keys and the Bahamas in the 1990s. Since then, invasive red lionfish have been reported as far north as Rhode Island and, as of this January, tracked to the southern Gulf of Mexico off the Yucatan Peninsula.

From the Community: Atlantic garbage soup, rerouting the Red Sea and misnaming the fruit fly

Scientists develop a project to reroute water into the Dead Sea, male wasp spiders get a second chance at mating if they start with their sisters, 25% of fish in Dublin is mislabeled as completely different species and five species that cheated extinction. Here is the latest news in ecology for the third week in April.

The sharp shooters of marine life

The archerfish’s long distance spitting can fire a bug off of a branch and send it down to the water’s surface, and the nearly-blind pistol shrimp uses its gigantic claw to stun its prey with a bubble nearly as hot as the Sun. However, if the archerfish didn’t have keen eyes enabling it to detect an insect against a vegetative background, and if the pistol shrimp lacked its protective eye covers, called orbital hoods, these animals might never have developed the ballistic mechanisms that characterize them.

Life between extinctions: cracking open the Cretaceous period

One hundred million years ago, Earth experienced its first great peak in biodiversity. Flowers emerged and with them pollinators, dinosaurs towered over newly evolved mammals and marsupials, the steaming jungles were teeming with newly arrived ants and termites, and the oceans were filled with gigantic, air-breathing reptiles. This was life during the Cretaceous period, Earth between two great extinctions.

Scientists and filmmakers are making “Waves” together

Even though most of my face was covered by neoprene, acrylic glass and rubber, I could still feel the whiskers of the harbor seal rub against my skin as he repeatedly kissed my face. Believe it or not, the harbor seal wasn’t the only marine organism that was showing me the love during a morning of scientific diving in a marine reserve off the coast of Catalina Island, California.

Scientists discuss some of the 5,000 new marine species discovered through census

Today at the American Association for the Advancement of Science annual meeting in San Diego, scientists participating in the Census of Marine Life (CoML) announced that the $650 million, 10-year collaboration will conclude on October 4-6, 2010 in London. More than 2,000 scientists from 80 countries have been collecting data on the diversity, distribution and abundance of marine life worldwide. One goal of CoML is to provide the...
