(PhysOrg.com) — Microsoft has been secretly developing a prototype booklet-shaped tablet PC called the Courier, according to an exclusive report in the gadget blog “Gizmodo”. It is not known when, or even if, the device will be released, and it is also unclear if the “leak” to Gizmodo was sanctioned by Microsoft. There is, however, no indication the Courier will be unveiled at the January 2010 International Consumer Electronics Show in Las Vegas, which would be expected if its release was likely to be within the next year. The Courier is also said to be just one of several tablet PC ideas Microsoft is developing.via Gizmodo© 2009 PhysOrg.com

Skulls of various Canid genera; Vulpes (corsac fox), Nyctereutes (raccoon dog), Cuon (dhole) and Canis (golden jackal) Credit: Wikipedia. A group of researchers in Sweden, Switzerland and Brazil have collaborated on a study of North American canids to show that competition from multiple carnivore clades is responsible for the ultimate demise of two extinct canid subfamilies. They theorize that the competitive processes driving these extinctions are more prevalent in species diversification than previously believed. The study is published in the Proceedings of the National Academy of Sciences. The North American fossil record provides abundant evidence for the evolutionary history of the dog family Canidae and of other major carnivores. The researchers analyzed around 1,500 fossil occurrences for 120 canid species from around 40 million years ago to the present; theorizing that competition from other species was a factor driving extinction rates, they also compiled data for five additional carnivore families including cats, bear dogs, false saber-tooth cats, and bears. They developed an analytical framework to invesigate whether speciation and extinction rates responded to evolution of body mass—a good approximation of diet for canids. The authors suggest that body size can indirectly correlate with diversification dynamics as increases in size predispose the development of hypercarnivory behaviors and selective feeding. These adaptive constraints place canids in danger of extinction by restricting their possible sources of food.Via a Bayesian analytic framework, the researchers have determined that the two extinct subfamilies that form the basis of their study were ultimately wiped out by the competitive effects of other carnivore clades, previously considered a rare occurrence, but increasingly regarded as an important influence on biodiversity.Climate change events are widely believed to be a main driver of extinction and speciation, but the study strongly suggests an important role for competition between different species with similar ecologies. Two biologic mechanisms drive clade replacement: passive replacement and active displacement. In the case of passive replacement, an incumbent carnivore clade prevents a competitor population from radiating. The competitor can only radiate once the incumbent carnivore clade declines.Active displacement is the process by which a clade’s rise in diversity causes the decline of another clade by outcompeting for limited resources. “The demise of nonavian dinosaurs by the Cretaceous-Paleogene meteorite impact around 66 million years ago and the subsequent evolutionary and ecologic diversification of mammals provide an iconic example of passive replacement,” the authors write.The authors found evidence for significant changes in speciation and extinction rates for the two extinct canid subfamilies, Hesperocyoninae and Borophaginae, suggesting strongly that the demise of a clade is driven by both its rate of extinction and its failure to originate. The researchers report that changes in in the speciation and extinction rates of the two extinct canid groups were strongly correlated with changes in diversity of multiple competitors. “Our results strongly indicate that competition among several clades of canids and other carnivores drove the changes in diversification rates and the replacement of entire clades,” they write.

The rise and demise of these branches (clades) are ultimately determined by changes in speciation and extinction rates, often interpreted as a response to varying abiotic and biotic factors. However, understanding the relative importance of these factors remains a major challenge in evolutionary biology. Here we analyze the rich North American fossil record of the dog family Canidae and of other carnivores to tease apart the roles of competition, body size evolution, and climate change on the sequential replacement of three canid subfamilies (two of which have gone extinct). We develop a novel Bayesian analytic framework to show that competition from multiple carnivore clades successively drove the demise and replacement of the two extinct canid subfamilies by increasing their extinction rates and suppressing their speciation. Competitive effects have likely come from ecologically similar species from both canid and felid clades. These results imply that competition among entire clades, generally considered a rare process, can play a more substantial role than climate change and body size evolution in determining the sequential rise and decline of clades. Explore further (Phys.org)—Over long spans, biodiversity is a fluid and shifting balance of species and influences. Species diversification occurs in response to a host of complex factors, both biotic and abiotic, and understanding them is a major challenge of evolutionary biology.

Baguiati police station was immediately informed. Within few minutes police arrived at the spot and rescued the driver identified as Akhya Nayak (42) along with one passenger identified as Nazrul Islam and admitted them to the R G Kar Medical College and Hospital where doctors declared Nayak dead. Islam is still undergoing treatment. Also Read – Lightning kills 8, injures 16 in stateAccording to a local, driver of the app cab applied brake at the last moment but that did not help. Sleuths suspect that driver had fallen asleep and woke up at the last moment when the passenger alerted him. It is also suspected that Nayak had been driving all through the night and as a result he had fallen asleep. The police are waiting for Islam recovery to question him as he is the only person who knows what exactly happened. Earlier during January this year, an app cab was moving towards Chingrihata from Science City with four passengers. Near Metropolitan Housing Complex, the driver identified as Ajay Roy lost control and collided with a median divider on E M Bypass. Later, police came to know that the driver had driven throughout the night and had fallen asleep while driving and lost control over the vehicle. In May, last year, an IT professional died after an app cab rammed into a stationary container at Baguiati Joramandir. In this case too, sleuths later came to know that driver had fallen asleep. These accidents are taking place often. The cops are planning to talk to app cab authorities to ask them not to schedule early morning trips for those drivers, who had been driving throughout the night.
