New chameleon species discovered in East Africa
November 24, 2009Dr Andrew Marshall, from the Environment Department at the University of York, first spotted the animal while surveying monkeys in the Magombera Forest when he disturbed a twig snake eating one.
The specimen was collected, tested and compared to two others found by scientists in the same area and has now been named Kinyongia magomberae (the Magombera chameleon) in research published in the African Journal of Herpetology.
Dr Marshall is co-author of the study alongside researchers from the Museo Tridentino di Scienze Naturali, the South African National Biodiversity Institute, Anglia Ruskin University and the University of Stellenbosch.
He said: "Discovering a new species is a rare event so to be involved in the identification and naming of this animal is very exciting.
"Chameleon species tend to be focused in small areas and, unfortunately, the habitat this one depends on, the Magombera Forest, is under threat. Hopefully this discovery will support efforts to provide this area and others like it with greater protection."
Dr Marshall, who is also Director of Conservation Science at the Flamingo Land theme park and zoo, is leading a research project investigating changes in the Magombera Forest. The forest is an important resource for people in the area and home to wildlife, including endangered red colobus monkeys.
The project combines research into the biology of the forest with education for local people on how to manage it in a more sustainable way. The ultimate aim is to develop protected status for the forest and find alternative ways of meeting the needs of local communities.

Chameleon Current Events and Chameleon News RSSSecret Lives of Catalysts Revealed
The first-ever glimpse of nanoscale catalysts in action could lead to improved pollution control and fuel cell technologies. Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory observed catalysts restructuring themselves in response to various gases swirling around them, like a chameleon changing its color to match its surroundings.
Unheard of life history for a vertebrate
There is a newly discovered life history among the 28,300 species of known tetrapods, or four-legged animals with backbones.
'Smart' sunglasses and goggles let users adjust shade and color
Imagine a single pair of glasses with lenses that can be transparent or dark, and in shades of yellow, green or purple, all on command. A new lens with chameleon powers promises to dramatically improve sunglasses' function.
Scientists develop a new way to target Alzheimer's disease
The pathological embrace between two proteins plays a key role in the development of Alzheimer's disease by triggering the formation of neuron-killing plaques of amyloid beta protein. Now a group of scientists at NYU School of Medicine have devised a way to reduce amyloid beta deposition by interfering with the deadly embrace of these proteins.
Watching how planets form
With the VISIR instrument on ESO's Very Large Telescope, astronomers have mapped the disc around a star more massive than the Sun. The very extended and flared disc most likely contains enough gas and dust to spawn planets.
Chameleon-chip adapts itself and stays cool
A microprocessor adapting itself to the actual use and environment. That's the way to keep the energy consumption of future 'mobile companions' within limits and be flexible at the same time. Paul Heysters, who finishes his PhD-research at the University of Twente on September 24, developed a new type of processor. His 'Montium' is a reconfigurable processor adapting itself towards low energy consumption. It is possible to get ten times better performance, with ten times lower energy consumption at the same time, according to Heysters. He did his research at the Centre for Telematics and Information Technology of the University of Twente in The Netherlands.
Future smart mobile has to be a true chameleon
By continously adapting the receiver settings of a mobile phone to the current conditions, the advantage is twofold; facing bad reception, the connection can be improved while in good conditions, the energy consumption can be reduced. This is possible by an automatic controller developed by Lodewijk Smit of the University of Twente in The Netherlands. Smit did his PhD work on this, within the Centre of Telematics and Information Technology (CTIT). The mobile connection can be optimized by frequently evaluating the quality and adapting the receiver of the mobile device to this level. The conditions are continuously changing. Hence, the quality of the reception is fluctuating. Modern phones wi
Chameleon particles from the Sun
The Sun emits electron-neutrinos, elementary particles of matter that have no electric charge and very little mass, created in vast numbers by the thermonuclear reactions that fuel our parent star. Since the early 1970s, several experiments have detected neutrinos arriving on Earth, but they have found only a fraction of the number expected from detailed theories of energy production in the Sun. This meant there was either something wrong with our theories of the Sun, or our understanding of neutrinos. It turns out that our theories of how the Sun is powered look like being correct according to a team of scientists from the UK, the US and Canada whose latest results from research into solar
Going Ballistic: Soft Structures Could Spell The End For Slow Shrimps
Many animals are able to rapidly extend their tongues to catch prey. In fact, the chameleon extends its tongue at an acceleration rate of 500 metres per second square - generating 5 times the G force experienced by an F-16 fighter during its most demanding maneouvre! New research presented at the Society for Experimental Biology conference in Swansea today has shed light on exactly how these remarkable feats are achieved. Dr Johan van Leeuwen of Wageningen University, the Netherlands, suggests that these `ballistic movements` are possible due to nature`s remarkable `soft body mechanics`. In research which has studied the bullet-like extension of squid tentacles and snake and chameleon tongue
Nature press release for 14 February issue
[415787] EVOLUTION: BATTLE OF THE SEXES (pp787-789) As Valentines Day hoves into view, think on this: the toilet seat up or down debate is, metaphorically, going on all over the animal kingdom. Evolutionary conflicts of interest between the sexes occur in many animal species, and may result in an 'arms race' between males and females, as illustrated on the cover of this week`s Nature, which shows a male and a female water strider (Gerris lacustris) engaged in a violent pre-mating 'wrestling match'. The battle of the sexes can lead to an evolutionary standstill. The advantage gained by one sex is matched by analogous counteradaptations in the other sex, but examples of this in action are hard

Chameleon by Charles R. Smith Jr. (Author) In his first novel, the Coretta Scott King Author Honor winner evokes the bittersweet summer of transition for an L.A. teen. Shooting the breeze with his boys. Tightening his D on the court. Doing a color check — making sure nobody's wearing blue or red, which some Crip or Piru carrying a cut-down golf club would see as disrespect. Then back to Auntie's, hoping she isn't passed out from whiskey at the end of the day. Now that Shawn is headed for high school, he wonders if he'd be better off at the school in Mama's neighborhood, where he'd be free of Compton's hassles. But then he wouldn't be with his fellas — cracking jokes, covering each other's backs — or the fine Marisol, who's been making star appearances in his dreams. Dad says he needs to make his own decision, but what... |
