Scientific Name Finally Given To A Widely Distributed Red Alga From New Zealand
2013-03-28 16:06:17

Pensoft Publishers The most commonly occurring red alga in the algal order Bangiales in New Zealand has at last received a formal scientific name. Pyropia plicata, is an intertidal red alga, found in abundance in the North, South and Chatham Islands. It has been confused for many years with a species first collected from the New Zealand subantarctic islands in 1840. Recent research had clarified the identity and distribution of the southern species, Porphyra columbina, and also transferred...

Limited Phosphorus Makes Gulf Of Mexico Algae Even Meaner
2013-03-13 10:27:32

North Carolina State University When Gulf of Mexico algae don't get enough nutrients, they focus their remaining energy on becoming more and more poisonous to ensure their survival, according to a new study by scientists from North Carolina State University and the National Oceanic and Atmospheric Administration. The study shows that harmful and ubiquitous Karenia brevis algae, which cause red tide blooms across the Gulf of Mexico, become two to seven times more toxic when levels of...

Space Algae Claims Scoffed By Science Community
2013-03-12 10:23:24

Brett Smith for redOrbit.com - Your Universe Online Instead of being hailed as the definitive proof of extraterrestrial life in the form of space algae, a new report from the Journal of Cosmology claiming drawing howls and catcalls from around the scientific community. The report is based on supposed meteorite fragments taken from a fireball that appeared in the evening sky over northern Sri Lanka on Dec. 29, 2012. An analysis of the fragments was performed by Chandra Wickramasinghe,...

Red Tide Killing Record Number Of Manatees In Florida
2013-03-11 10:44:02

Brett Smith for redOrbit.com - Your Universe Online A red algae bloom, also known as Red Tide, is currently killing a record number of manatees living off the coast of Florida. Last week, the Florida Fish and Wildlife Conservation Commission (FWC) found an average of 10 dead manatees a day and some observers said the phenomenon doesn´t appear to be receding. A toxin produced by the red algae affects the nervous system of the manatees causing them to drown. "This is probably...

Extreme Algae Thieves Its Genes From Bacteria
2013-03-08 17:34:16

Brett Smith for redOrbit.com - Your Universe Online Some microorganisms have developed the ability to thrive in the most hostile environments on Earth, from the superheated geothermal vents to pools of toxic drainage deep underground. According to a new study in the journal Science, researchers have found evidence one of these so-called “extremophiles” steals its ability to endure extreme environments from the organisms around it. While the ability to pilfer genes from...

Biologists Produce Rainbow-Colored Algae
2013-03-07 15:51:10

University of California, San Diego What can green algae do for science if they weren´t, well, green? That´s the question biologists at UC San Diego sought to answer when they engineered a green alga used commonly in laboratories, Chlamydomonas reinhardtii, into a rainbow of different colors by producing six different colored fluorescent proteins in the algae cells. While fluorescent green, red, blue and yellow may be all the rage this year for running shoes and other kinds...

Using a world-first scientific discovery, Australian researchers are developing a stress-test for coral, to measure how coral reefs are being impacted by pressures from climate change and human activity. The scientists have found hemoglobin genes in the microalgae which live symbiotically with coral, which may provide a readout on how stressed a particular coral is — and how likely it is to bleach and die. Coral bleaching occurs when the symbiotic algae abandon the coral due to...

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...

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...
