Determining Sexual Selection In Extinct Species
2013-01-30 08:11:48

Brett Smith for redOrbit.com - Your Universe Online According to a new study in the journal Trends in Ecology and Evolution, determining if certain extinct animals had sexually selective traits is possible, despite the fact that we cannot observe their behavior. Many animals have sexually selective traits that are used or displayed in pursuit of a mate, male peacocks have their colorful plumage and mallard ducks have a distinct green coloration to their head feathers. Some of these...

New Study Debunks Claims That Most Species Will Vanish Before They Are Discovered
2013-01-25 11:54:53

April Flowers for redOrbit.com - Your Universe Online A new study from researchers at the University of Auckland, Griffith University and the University of Oxford has debunked claims that most species will go extinct before they can be discovered. "Surprisingly, few species have gone extinct, to our knowledge. Of course, there will have been some species which have disappeared without being recorded, but not many we think," Professor Nigel Stork, Deputy Head of the Griffith School of...

When Charles Darwin first sketched how species evolved by natural selection, he drew what looked like a tree. The diagram started at a central point with a common ancestor, then the lines spread apart as organisms evolved and separated into distinct species. In the 175 years since, scientists have come to agree that Darwin´s original drawing is a bit simplistic, given that multiple species mix and interbreed in ways he didn´t consider possible (though you can´t fault the guy...

Researchers Find Bornean Elephants Have Low Genetic Variability
2012-11-23 12:53:02

Lee Rannals for redOrbit.com — Your Universe Online A research lab has identified the genetic markers for an endangered species of elephant, showing the animals have very low genetic variability. The study, published in the journal PLoS ONE, opens up new avenues for the conservation of other endangered species. Researchers took advantage of DNA sequencing methodology in order to try and change the odds when looking for diversity. The Bornean elephant is a unique...

Ocean May Contain One Million Species Or More
2012-11-16 12:36:12

Alan McStravick for redOrbit.com - Your Universe Online A vast undertaking has been launched to catalog the life that inhabits our world´s oceans. For the first time, a comprehensive register of marine species has been compiled. This effort was part of a massive collaboration among hundreds of experts around the globe. Findings detailed in this report claim that one-third of all species that inhabit the world´s oceans may actually still remain completely unknown to science....

Evolution Follows A Predictable Genetic Pattern Researchers Find
2012-10-26 10:20:03

Evolution, often perceived as a series of random changes, might in fact be driven by a simple and repeated genetic solution to an environmental pressure that a broad range of species happen to share, according to new research. Princeton University research published in the journal Science suggests that knowledge of a species' genes – and how certain external conditions affect the proteins encoded by those genes – could be used to determine a predictable evolutionary pattern...

Fossil Record Helps Determine Extermination Risk In Marine Animals
2012-10-24 10:27:12

Brett Smith for redOrbit.com - Your Universe Online Conservationists have warned for years that rare species have the highest risk of becoming endangered or extinct, but the word “rare” could have several different meanings with respect to the distribution of particular species. An international team of researchers from Stanford University in California and Humboldt University in Berlin decided to parse the definition of “rare” with respect to conservation and...

Evolutionary Tree Of Life Goes Digital
2012-10-17 13:25:34

Brett Smith for redOrbit.com - Your Universe Online Evolutionary biologists have long envisioned creating a diagram, or tree of life, that would detail how different species have evolved from a common ancestry, but the task has been a daunting one for taxonomists who would need multiple reams of paper or computer screens to clearly show the evolutionary descent of each species. A research associate at the Imperial College London, however, has risen to the challenge and created OneZoom,...

DNA barcoding developed by University of Guelph researchers has proven up to 88 per cent effective in authenticating natural health products, according to a new U of G study. The study appears in the latest issue of Food Research International. It´s a crucial finding because the health product industry is under-regulated worldwide and mislabeling poses economic, health, legal and environmental implications, says study author Mehrdad Hajibabaei. “Currently there is no other...

Female Pit Vipers Give Birth Without Mating
2012-09-12 12:04:30

Brett Smith for redOrbit.com - Your Universe Online In what could be the ultimate act of feminism, wild female North American pit vipers have been shown to give birth without mating, according to a new report published in the Royal Society's Biology Letters. A phenomenon, known as facultative parthenogenesis (FP), has been observed in captivity before and the report asserts that it can occur regardless of the presence of male individuals. “In these populations, males are...

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...
