Travels in northeastern Brazil: Unfolding the reptile fauna of Lençóis Maranhenses

Travels in northeastern Brazil: Unfolding the reptile fauna of Lençóis Maranhenses
2012-11-29
(Press-News.org) In order to be effective, a Conservation Unit must have available a list of the species that live within it. They also should have detailed information about the distribution of species among the available habitats. It would be difficult to correctly plan the conservation actions and/or monitoring programs without some minimal knowledge about the species (who are the object of those measures). "This is why our study is so important to the park", said Dr. Miranda from Universidade Federal do Maranhão (CCAA/UFMA), leading author of the article, published in the open access journal Zookeys.

In Lençóis Maranhenses National Park 42 species of reptiles were found. Approximately 80% of them live only in restinga habitats, which comprise about 20% of the area currently protected by the park. Restingas have been strongly disturbed by the clandestine openings of paths created to transport tourists to the dunes in the park, using off-road vehicles. This problem is more severe during the rainy season when paths become muddy quickly, and new ones are continuously opening. This could be extremely harmful to those habitats because their poor soil might severely limit natural recomposition.

"We recorded endangered species in Lençóis Maranhenses; particularly sea turtles located in the beach habitats. No one has any idea about the animal activity there! Are they spawning? It's very likely, but we don't have any data! It would be very important to study and monitor those species in the 70 km of beaches of the Lençóis Maranhenses National Park" adds Dr. Miranda.

Another turtle species, which deserves attention in Lençóis Maranhenses, is the Brazilian Slider Turtle, which has a limited geographic distribution in the coast of Maranhão, northeastern Brazil. This turtle is used as a source of food by the extremely poor inhabitants of Lençóis Maranhenses and surrounding areas.

"We believe that it would be helpful to promote awareness campaigns to help the conservation of that species, but it is equally important to provide alternatives to the people that live there. These inhabitants, for example, could be placed into the tourism business by providing training courses. They could work as tourist guides, waiters, or cooks. This would not only improve their economic capacity, but also free them of the need to use the Brazilian Slider Turtle as a food item. The efforts for conservation will only be successful with a joint effort of scientists, policymakers and society. We have to talk to one another and look for solutions together", concluded Dr. Miranda.

An ocean away: 2 new encrusting anemones found in unexpected locations

An ocean away: 2 new encrusting anemones found in unexpected locations
2012-11-29
As a result of field work by associate professor James Davis Reimer and two graduate students from the University of the Ryukyus in Okinawa, Japan has found two new species of encrusting anemones, or colonial zoanthids, in unexpected locations. The species belong to the genus Neozoanthus, which was previously known only from a single species in the Indian Ocean. Surprisingly, the new species were found in the Pacific Ocean, in southern Japan and on the Great Barrier Reef, Australia. The study was published in the open access journal ZooKeys. The only previous species ...

Black hole upsets galaxy models

Black hole upsets galaxy models
2012-11-29
This press release is available in German. A group headed by Remco van den Bosch from the Max Planck Institute for Astronomy has discovered a black hole that shakes the foundations of current models of galaxy evolution. This monster has 17 billion solar masses and is thus significantly heavier than the models predict. And even more significantly: the object could be the most massive black hole known to date. Astronomers believe there is a super-massive black hole at the heart of every galaxy. Its mass ranges from several hundred thousand solar masses to a few billion. ...

Inviting customer complaints can kill business: UBC research

2012-11-29
Giving customers a chance to complain can be a bad idea if customers believe they're to blame for a product's failure, a new study from the Sauder School of Business at UBC shows. "It's commonly assumed that giving customers a chance to voice grievances allows companies to maintain relationships," says Marketing Professor Darren Dahl, who co-authored the recent Journal of Marketing study with PhD student Lea Dunn. "But our research shows that when a person feels implicated in a product's failure – think building Ikea furniture – they're more likely to shift blame to ...

Maths helps mobiles & tablets match eyes ability to switch from sunshine to shadow
2012-11-29
Researchers have pushed the boundaries of High Dynamic Range (HDR) video to match our own eyes' ability to cope with the real world's ever rapidly changing light intensity - such as sun simply going behind clouds. Now researchers at WMG at the University of Warwick, have found a way to compress and stream HDR video directly to monitors and mobile devices, such as an iPad, bringing enormous benefits to industries including gaming and security. Researchers at WMG at the University of Warwick, working in partnership with spinout company goHDR Ltd, have succeeded in achieving ...

First-ever hyperspectral images of Earth's auroras

First-ever hyperspectral images of Earths auroras
2012-11-29
WASHINGTON, Nov. 29—Hoping to expand our understanding of auroras and other fleeting atmospheric events, a team of space-weather researchers designed and built NORUSCA II, a new camera with unprecedented capabilities that can simultaneously image multiple spectral bands, in essence different wavelengths or colors, of light. The camera was tested at the Kjell Henriksen Observatory (KHO) in Svalbard, Norway, where it produced the first-ever hyperspectral images of auroras—commonly referred to as "the Northern (or Southern) Lights"—and may already have revealed a previously ...

Bacteria hijack host cell process, create their own food supply to become infectious

2012-11-29
COLUMBUS, Ohio – Bacteria that cause the tick-borne disease anaplasmosis in humans create their own food supply by hijacking a process in host cells that normally should help kill the pathogenic bugs, scientists have found. This bacterium, Anaplasma phagocytophilum (Ap), secretes a protein that can start this process. The protein binds with another protein produced by white blood cells, and that connection creates compartments that siphon host-cell nutrients to feed the bacteria, enabling their growth inside the white blood cells. The finding defies conventional wisdom ...

Insects beware: The sea anemone is coming

2012-11-29
Bethesda, MD—As insects evolve to become resistant to insecticides, the need to develop new ways to control pests grows. A team of scientists from Leuven, Belgium have discovered that the sea anemone's venom harbors several toxins that promise to become a new generation of insecticides that are environmentally friendly and avoid resistance by the insects. Since these toxins disable ion channels that mediate pain and inflammation, they could also spur drug development aimed at pain, cardiac disorders, epilepsy and seizure disorders, and immunological diseases such as multiple ...

Brain inflammation likely key initiator to prion and Parkinson's disease

2012-11-29
Prion diseases represent a family of neurodegenerative disorders associated with the loss of brain cells and caused by proteins called prions (derived from 'protein' and 'infection'). The diseases are found in both humans and animals, such as Creutzfeld-Jakob disease and mad cow disease respectively. Although mostly harmless, prions can transform into infectious agents, which accumulate in the brain and destroy the nervous tissue. But how exactly does the accumulation of prions cause destruction of the brain? "Understanding the process by which prions destroy neurons ...

New genetic test detects early breast cancer and identifies future risk

2012-11-29
Bethesda, MD—Physicians may now be better at detecting breast cancer than ever before, but much more work remains to ensure accurate diagnosis is possible and especially to assess future risk. That's why researchers from Germany have been working to develop a new test of gene action to predict cancer risk both at first diagnosis and into the future. In a new research report appearing in the December 2012 issue of The FASEB Journal, researchers show that the various genetic switches, which are turned on and off in the regular development of every cell in the body, can be ...

New approach allows past data to be used to improve future climate projections

2012-11-29
Climate scientists are still grappling with one of the main questions of modern times: how high will global temperatures rise if the atmospheric concentration of carbon dioxide doubles. Many researchers are turning to the past because it holds clues to how nature reacted to climate change before the anthropogenic impact. The divergent results of this research, however, have made it difficult to make precise predictions about the impact of increased carbon dioxide on future warming. An international team of scientists have evaluated previously published estimates and assigned ...
