Sea Star Disease Epidemic Surges In Oregon
2014-06-06 03:36:07

Oregon State University Just in the past two weeks, the incidence of sea star wasting syndrome has exploded along the Oregon Coast and created an epidemic of historic magnitude, one that threatens to decimate the entire population of purple ochre sea stars. Prior to this, Oregon had been the only part of the West Coast that had been largely spared this devastating disease. The ochre sea star, which is the species most heavily affected by the disease in the intertidal zone, may be...

Crustacean Sand-dwellers Suffering Localized Extinctions In Southern California
2013-07-18 11:14:11

University of California - Santa Barbara Two types of small beach critters -- both cousins of the beloved, backyard roly-poly -- are suffering localized extinctions in Southern California at an alarming rate, says a new study by UC Santa Barbara scientists. As indicator species for beach biodiversity at large, their disappearance suggests a looming threat to similar sand-dwelling animals across the state and around the world. Led by David Hubbard and Jenifer Dugan of UCSB's Marine...

New Research On Seaweeds Shows It Takes More Than Being Flexible To Survive Crashing Waves
2012-05-10 12:58:48

Bladed and branched algae adapted to strong wave conditions are able to reconfigure their shape and size Seaweeds are important foundational species that are vital both as food and habitat to many aquatic and terrestrial shore organisms. Yet seaweeds that cling to rocky shores are continually at risk of being broken or dislodged from their holds by crashing waves with large hydrodynamic forces. So how do such seaweeds survive in intertidal zones? Do they have special properties that make...

2010 Chile Earthquake Had Surprising Ecological Effects

Long-forgotten coastal habitats reappeared, species unseen for years returned 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 found in a study of 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...

First-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. In a scientific first, researchers from Universidad...

Image 1 - NOAA Designates Critical Habitat For Black Abalone
2011-10-27 11:57:26

NOAA's Fisheries Service on Oct. 26 filed with the Federal Register a final rule that identifies black abalone critical habitat along the California coast. In February 2009, black abalone was listed as endangered under the Endangered Species Act, and the Act requires critical habitat be designated, to the maximum extent prudent and determinable, whenever a species is listed for protection. Once areas are designated as critical habitat, federal projects or permits and projects with federal...

One of the world's strangest animals — a unique fish that lives on land and can leap large distances despite having no legs — has a rich and complex social life, a new study has found. The odd lifestyle of the Pacific leaping blenny (Alticus arnoldorum) has been detailed for the first time in research findings that throw new light on how animal life first evolved to colonies the land. The Pacific leaping blenny is a marine fish yet is terrestrial in all aspects of its daily...

The barnacle, a key thread in the marine food web, was thought to be missing along rocky coasts dominated by upwelling. Now a research team headed by Brown University marine ecologist Jon Witman has found the opposite to be true: Barnacle populations thrive in vertical upwelling zones in moderately deep waters in the Galapagos Islands. The findings appear in Ecological Monographs. There's been a rich debate in marine ecological circles about what happens to a key food source along rocky...

A new study finds that a species of sea star stays cool using a strategy never before seen in the animal kingdom. The sea stars soak up cold sea water into their bodies during high tide as buffer against potentially damaging temperatures brought about by direct sunlight at low tide. "Sea stars were assumed to be at the mercy of the sun during low tide," said the study's lead author, Sylvain Pincebourde of François Rabelais University in Tours, France. "This work shows that...

The White Acorn Barnacle (Balanus glandula), is one of the most common barnacle species on the Pacific coast of North America. It is widely distributed from the coast of Alaska to the border between California and the Mexican state of Baja California. They are commonly found in intertidal waters on mussels, rocks and pier pilings. It is moderately sized with a length of 0.6 to 0.8 inches. The shell is formed by overlapping plates. It is shaped more like a cylinder rather than a cone. The...

  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
