Speciation Theory Questioned
2013-09-03 14:24:14

Brett Smith for redOrbit.com - Your Universe Online While scientists have catalogued millions and millions of species, there is still no agreement on how exactly new species form. However, a new study published this week in Proceedings of the National Academy of Sciences could deal a major blow to one prevailing theory - namely, that new species arise when a barrier prevents reproduction between populations. Species-creating barriers could be physical, such as a mountain range, or they...

Ray Wings Sold To Consumers Can Be MislabeledAnd Include Vulnerable Species
2013-08-13 12:11:30

PeerJ Genetic testing by DNA Barcoding, has revealed which species are sold under the commercial term 'ray wings' in Ireland and the UK. The blonde ray, given the lowest rating for sustainability in the marine conservation society's good fish guide, was the most widely sold. Samples from the only retailer to label products as originating from more sustainable sources demonstrated high levels of mislabelling, substituted by more vulnerable species. Therefore, consumers cannot make informed...

Fossil And Molecular Evidence Important For Studying Evolution
2013-08-10 05:19:24

redOrbit Staff & Wire Reports - Your Universe Online The fossils of microscopic aquatic creatures, whose shells resemble grains of sand to the naked eye, could help shed new light on the process of evolution, according to new research published Friday in the journal Methods in Ecology & Evolution. As part of their research, University of Southampton evolutionary ecologist Dr. Thomas Ezard and his colleagues are analyzing the remains of the one-millimeter large planktonic...

Sequencing DNA Of 'Insect Soup' Can Accelerate Monitoring And Cataloguing Of Biodiversity Around The World
2013-08-05 08:57:18

University of East Anglia Research published today in the journal Ecology Letters shows that a process known as 'metabarcoding' is much faster than and just as reliable as standard biodiversity datasets assembled with traditional labor-intensive methods. The breakthrough means that changing environments and endangered species can be monitored more easily than ever before. It could help researchers find endangered tree kangaroos in Papua New Guinea, discover which moths will be wiped out...

Madagascar No Longer An Evolutionary Hotspot Research Suggests
2013-07-10 16:49:38

University of Rochester Madagascar has long been known as a hotspot of biodiversity. Although it represents only one percent of the earth's area, it is home to about three percent of all animal and plant species on the planet. But research suggests the island's heyday of species development may be all but over. "A staggering number of species are found only on Madagascar," said Daniel Scantlebury, a Ph.D. student in biology, "but this research shows there are limits to the number of...

Evolution Not Fast Enough For Climate Change
2013-07-10 15:17:43

Brett Smith for redOrbit.com - Your Universe Online New research from two biologists at the University of Arizona and Yale suggests that evolution is not an option for species looking to cope with rising global temperatures. According to a study, terrestrial vertebrate species could not adapt to the 4 degree Celsius rise in average global temperatures, and many of these species could be driven to extinction. "Every species has a climatic niche, which is the set of temperature and...

As past extinctions show, groups must continually adapt and evolve or they disappear The death of individual species is not the only concern for biologists worried about groups of animals, such as frogs or the "big cats," going extinct. University of California, Berkeley, researchers have found that lack of new emerging species also contributes to extinction. "Virtually no biologist thinks about the failure to originate as being a major factor in the long term causes of extinction,"...

Females Choose Biological Fitness Over Other Traits In Mating Game
2013-06-20 10:46:19

National Institute for Mathematical and Biological Synthesis When a new species emerges following adaptive changes to its local environment, the process of choosing a mate can help protect the new species' genetic identity and increase the likelihood of its survival. But of the many observable traits in a potential mate, which particular traits does a female tend to prefer? A new study from the National Institute for Mathematical and Biological Synthesis finds that a female's mating...

Efforts to restore sturgeon in the Great Lakes region have received a lot of attention in recent years, and many of the news stories note that the prehistoric-looking fish are "living fossils" virtually unchanged for millions of years. But a new study by University of Michigan researchers and their colleagues reveals that in at least one measure of evolutionary change–changes in body size over time–sturgeon have been one of the fastest-evolving fish on the planet. "Sturgeon...

Paleozoology
2013-09-30 13:34:57

Paleozoology, also spelled Palaeozoology, is a branch of many other sciences including zoology and paleontology that focuses on recovering cellular matter from animal remains that are large enough to be seen without the help of a microscope, known as macrofossils. This study is primarily used in the context of archeology and geology and aids in recreating ancient ecosystems and prehistoric environments. Paleozoologists study the tissues of many types of animals including sharks, echinoderms,...

The Three-Spined Stickleback, Gasterosteus aculeatus, is a fish native to much of northern Europe, northern Asia and North America. It has been introduced into parts of southern and central Europe. Three subspecies that are currently recognized by the IUCN are Gasterosteus aculeatus aculeatus, which is found in most of the species range, and is the subspecies most strictly termed the Three-Spined Stickleback; its common name in England is the Tiddler, although "tittlebat" is also sometimes...

callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
