Caribbean crustacean named after Bob Marley


This video is about the crustacean, recently called after Bob Marley.

From the Christian Science Monitor:

Better than nothing? Bloodsucking parasite named after Bob Marley.

Gnathia marleyi, a tiny crustacean that feeds off the blood of reef-dwelling Caribbean fish, has been named in honor – for lack of a better term – of the Jamaican musician Bob Marley.

The late Jamaican musician Bob Marley has joined the “I have a species named after me” club, as a parasitic crustacean has been donned Gnathia marleyi, researchers announced today (July 10).

This blood feeder infests certain fish that live among the coral reefs of the shallow eastern Caribbean Sea.

“I named this species, which is truly a natural wonder, after Marley because of my respect and admiration for Marley’s music,” Paul Sikkel, an assistant professor of marine ecology at Arkansas State University, said in a statement. “Plus, this species is as uniquely Caribbean as was Marley.”

Marley now belongs to a club that includes President Barack Obama, whose name inspired Caloplaca obamae, the moniker for a lichen growing on Santa Rosa island in California. Late-night comedian Stephen Colbert has two insects named for him, while Mick Jagger‘s name was given to an extinct trilobite, Aegrotocatellus jaggeri.

Juvenile gnathid isopods hide within coral rubble or algae so they can launch surprise attacks on fish, and then infest them. As adults, the parasites don’t eat. “We believe that adults subsist for two to three weeks on the last feedings they had as juveniles and then die, hopefully after they have reproduced,” Sikkel said in a statement.

With reports suggesting coral reef communities in the Caribbean are declining due to diseases, Sikkel’s team is examining whether there’s a link between reef health and gnathid populations. G. marleyi, like other gnathids, is similar to blood-sucking ticks or mosquitoes.

And like the land-lubbing ticks, gnathids are responsible for many diseases, in thise case those afflicting coral-reef fish, the researchers said. “We suspect that coral degradation leads to more available habitat for external parasites to ‘launch attacks’ on host fishes,” he said. “And as the number of potential host fish decreases, each remaining host will become more heavily parasitized.”

Sikkel first discovered the newly identified gnathid about 10 years ago in the U.S. Virgin Islands, where it was so common he assumed it had been described. Not so, according to Nico J. Smit of North-West University in South Africa, who later examined a specimen of the species. Next, the research team raised the organism from its juvenile stage through adulthood.

Sikkel and his team describe all of G. marleyi’s life stages in the June 6 issue of the journal Zootaxa.

With sea ice in the Arctic melting to record lows in summer months, marine animals living there face dramatic changes to their environment. Yet some crustaceans, previously thought to spend their entire lives on the underside of sea ice, were recently discovered to migrate deep underwater and follow ocean currents back to colder areas when ice disappears: here.

Big fossil turtle discovered in Colombia

From the Smithsonian Tropical Research Institute in Panama:

Fossil turtle from Colombia round like car tire

Paleontologist Carlos Jaramillo‘s group at the Smithsonian Tropical Research Institute in Panama and colleagues at North Carolina State University and the Florida Museum of Natural History discovered a new species of fossil turtle that lived 60 million years ago in what is now northwestern South America. The team’s findings were published in the Journal of Paleontology.

The new turtle species is named Puentemys mushaisaensis because it was found in La Puente pit in Cerrejón Coal Mine, a place made famous for the discoveries, not only of the extinct Titanoboa, the world’s biggest snake, but also of Carbonemys, a freshwater turtle as big as a smart car.

Cerrejon’s fossil reptiles all seem to be extremely large. With its total length of 5 feet, Puentemys adds to growing evidence that following the extinction of the dinosaurs, tropical reptiles were much bigger than they are now. Fossils from Cerrejon offer an excellent opportunity to understand the origins of tropical biodiversity in the last 60 million years of Earth’s history.

The most peculiar feature of this new turtle is its extremely circular shell, about the size and shape of a big car tire. Edwin Cadena, post-doctoral fellow at North Carolina State University and lead author of the paper, said that the turtle’s round shape could have discouraged predators, including Titanoboa, and aided in regulating its body temperature.

The width of the turtle’s shell probably exceeded the maximum expansion of the Titanoboa’s mouth. Its circular, low-domed shape would have increased the area of the body exposed to the sun, helping the cold-blooded turtle warm to a temperature at which it was more active.

Russula elegans

Translated from the Dutch Mycological Society:

Very rare russulas after it rained cats and dogs

Wednesday, July 11, 2012

In the Reigersdaal area in Heerhugowaard after the abundant rain recently the very rare Russula elegans appeared. Russula elegans is an endangered species on the Red List. Only a few times it had been found with certainty in the Netherlands. Although most russulas appear later in the year, it seems that Russula elegans especially responds to abundant precipitation whether in summer or in autumn.

Second Great white egret nest hatches chick in Somerset

More egret success at Shapwick Heath National Nature Reserve in Somerset

July 2012. Natural England staff have confirmed a second Great white egret nest has hatched another great white egret chick. This follows three chicks fledging from June’s nesting attempt; the large, heron-like bird had not successfully bred in Britain until this year.

Natural England’s project officer for the species, Kevin Anderson said; “This species has never bred in Britain before – to have two successful nests in the first breeding year is remarkable.”

Volunteers have kept up a round-the-clock vigil to ensure that both nests have not been disturbed. Kevin added, “We’d like to thank our volunteers for their commitment and determination, especially during the continued wet weather – they’ve been brilliant.”

With another chick to keep an eye on, the volunteering effort will continue throughout July. The hope is that the new arrival will have successfully fledged within a few weeks and that Shapwick will soon be able to confirm a record season for its most exotic new breeding bird.

About great white egrets

The nest is made up of a mound of reeds lined with softer plant material, and concealed deep in the reedbeds. Usually 3 – 4 eggs are laid with the young looked after by both adults.

European population are estimated at over 24,000 pairs (Birdlife, 2004). The great white egret is the size of a grey heron, with similar habits but can be confused with the much smaller little and cattle egrets.

Great white egrets feed on a range of aquatic animals including fish, frogs and insects. In the breeding season the tip of their yellow bill turns black on both sexes, and they develop beautiful long plumes along the back.

The great white egret is distributed across most of the tropical and warmer temperate regions of the world, but is rather localised in southern Europe.
