It's All About Being Fat And Flexible For Corals Adapting To Climate Change
2014-07-10 03:47:46

By Pam Frost Gorder, Ohio State University Study suggests best targets for environmental conservation The future health of the world's coral reefs and the animals that depend on them relies in part on the ability of one tiny symbiotic sea creature to get fat—and to be flexible about the type of algae it cooperates with. In the first study of its kind, scientists at The Ohio State University discovered that corals—tiny reef-forming animals that live symbiotically with algae—are...

How Does Algal And Coral Cover Affect Microscopic Life That Call The Reef Home?
2014-07-07 03:56:00

By Michael Price, San Diego State University A new study by biologists at San Diego State University and Scripps Institution of Oceanography shows that inhabited coral islands that engage in commercial fishing dramatically alter their nearby reef ecosystems, disturbing the microbes, corals, algae and fish that call the reef home. The study’s lead author, Linda Wegley Kelly, is a postdoctoral scholar in the lab of SDSU virologist Forest Rohwer. She's been involved in some capacity...

Key To Adaptation Limits Of Ocean Dwellers Uncovered By Scientists
2014-07-02 03:35:33

Alfred Wegener Institute The simpler a marine organism is structured, the better it is suited for survival during climate change. Scientists of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, discovered this in a new meta-study, which appears today in the research journal Global Change Biology. For the first time biologists studied the relationship between the complexity of life forms and the ultimate limits of their adaptation to a warmer climate. While...

The ‘Melissa Loop’: Closing The Recycling Circle
2014-06-30 03:52:03

ESA The International Space Station welcomes up to eight supply vessels a year bringing oxygen, water and food for the six astronauts continuously circling our planet. Building, launching, docking and unloading these spacecraft is costly and time-consuming – is there a better way? Many mission designers dream of crewed spacecraft that require no resupplies. A vehicle that indefinitely recycles astronaut waste such as exhaled carbon dioxide and urine and turns it into fresh oxygen and...

How Did Algae Evolve To Switch Quantum Coherence On And Off?
2014-06-17 03:02:59

University of New South Wales A UNSW-led team of researchers has discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis. The function in the algae of this quantum effect, known as coherence, remains a mystery, but it is thought it could help them harvest energy from the sun much more efficiently. Working out its role in a living organism could lead to technological advances, such as...

How Does Red Tide Knock Out Its Competition?
2014-06-05 03:05:40

By Brett Israel, Georgia Institute of Technology New research reveals how the algae behind red tide thoroughly disables – but doesn't kill – other species of algae. The study shows how chemical signaling between algae can trigger big changes in the marine ecosystem. Marine algae fight other species of algae for nutrients and light, and, ultimately, survival. The algae that cause red tides, the algal blooms that color blue ocean waters red, carry an arsenal of molecules that disable...

Close-up Of Coral Bleaching Event Provided By UGA Ecologists
2014-06-04 03:39:05

Beth Gavrilles, University of Georgia Study documents corals before, during and after October 2009 episode New research by University of Georgia ecologists sheds light on exactly what happens to coral during periods of excessively high water temperatures. Their study, published in the journal Limnology and Oceanography, documents a coral bleaching event in the Caribbean in minute detail and sheds light on how it changed a coral's community of algae—a change that could have long-term...

Kailua-Kona, HI (PRWEB) May 21, 2014 Today, Nutrex Hawaii, announced the launch of Green Complete Superfood Powder. Green Complete uses natural vanilla to add a delicious flavor to the combination of Hawaiian Spirulina and organic greens (barley, broccoli, kale and wheatgrass), organic...

Native Algae Species Is To Blame For 'Rock Snot' Blooms In Rivers Worldwide
2014-05-08 03:00:48

[ Watch The Video: ‘Rock Snot’ Blooms Due To Native Algae ] Dartmouth College Recent growths not caused by human introductions or emergence of new genetic strain The recent blooms of the freshwater algae known as "rock snot" on river bottoms worldwide are caused by a native species responding to changing environmental conditions rather than by accidental introductions by fishermen or the emergence of a new genetic strain as widely believed, a Dartmouth College-led study...

Aquatic Algae Can See A Wide Spectrum Of Light
2014-05-02 03:00:50

[ Watch The Video: Algae “See” A Wide Spectrum Of Light ] Andy Fell, UC Davis Aquatic algae can sense an unexpectedly wide range of color, allowing them to sense and adapt to changing light conditions in lakes and oceans. The study by researchers at UC Davis was published earlier this year in the journal Proceedings of the National Academy of Sciences. Phytochromes are the eyes of a plant, allowing it to detect changes in the color, intensity, and quality of light so that the...

Kelp Forest
2013-04-19 19:29:03

Kelp forests are areas that are underwater with a high density of kelp. They’re recognized as one of the most dynamic and productive ecosystems on Earth. Smaller regions of anchored kelp are known as kelp beds. Kelp forests can be found worldwide throughout polar and temperate coastal oceans. In the year 2007, kelp forests were discovered in tropical waters near Ecuador as well. While they are physically formed by brown macroalgae of the order Laminariales, kelp forests offer a unique...

Masked Spinefoot, Siganus puellus
2013-03-15 12:10:27

The masked spinefoot, also called a decorated rabbitfish or masked rabbitfish, lives in shallow coral rich lagoons, and seaward reefs of the Indo-West Pacific, at depths of 10 to 100 feet. The body of the masked spinefoot is a yellow-orange that gradients into a pale blue or white belly. It also has vertical blue lines toward the head and horizontal lines near the tail. A black stripe extends from the bottom of the mouth and runs through the eye. Above the eye the stripe turns to dark...

Foxface Rabbitfish, Siganus vulpinus

Image Credit: Dr. Wayne Meadows (NOAA)/Wikipedia The foxface rabbitfish is found in coral rich lagoons, and reefs in the coastal water of the Western Pacific. Around the western Philippines, Indonesia, New Guinea, the Great Barrier Reef, New Caledonia, Caroline Islands, and the Marshall Islands. It has also been sighted around Vanuatu, Nauru, Kiribati, and recently Tonga. Adults usually swim in pairs, but the juveniles have been known to form schools. The adult foxface rabbitfish is...

Truncate Coralfish, Chelmonops truncatus

Credit: Richard Ling/Wikipedia (CC BY-SA 2.0) The truncate coralfish is specifically found in the coastal waters of Australia at depths up to 230 feet, around rocky reefs that have an abundance of algae. This fish is a species of butterfly fish that is also called the Eastern Talma. In Southern Australia the truncate coralfish is harvested largely for the aquarium trade, and is considered harmless to...

Siderastreidae is a family of colonial, reef building stony corals. Members of this family include symbiotic algae in their tissues which help provide their energy requirements. The World Register of Marine Species lists 7 genera within this family: Anomastraea, Coscinaraea, Craterastrea, Horastrea, Psammocora, Pseudosiderastrea, and Siderastrea. Corals in this family vary in form and include massive, thickly encrusting, columnar, and irregular forms. Corallites are linked by flowing...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
