Untangling The Branches Of The Tree Of Life
2013-05-15 10:33:57

Vanderbilt University These days, phylogeneticists — experts who painstakingly map the complex branches of the tree of life — suffer from an embarrassment of riches. The genomics revolution has given them mountains of DNA data that they can sift through to reconstruct the evolutionary history that connects all living beings. But the unprecedented quantity has also caused a serious problem: The trees produced by a number of well-supported studies have come to contradictory...

Study Proves Darwin's Theory That Productivity Increases Species Diversity
2013-05-14 06:49:07

April Flowers for redOrbit.com - Your Universe Online Charles Darwin predicted that a plot of land growing distantly related grasses would be more productive than a plot with a single species of grass in On The Origin of Species, first published in 1859. Over 150 years later, a new study from the University of Toronto Scarborough (UTSC), reveals Darwin was right; environments containing species that are distantly related to one another are more productive than those containing closely...

It's In The Genes: Europeans Have Been One Big Family For Past Thousand Years
2013-05-08 07:34:50

Lawrence LeBlond for redOrbit.com - Your Universe Online If there is one thing you can say about families, it is the larger the better. And by looking at genetic data of people from Ireland to the Balkans, researchers have found that Europeans are one big family, and have been for the past thousand years. Graham Coop, a professor of evolution and ecology at UCDavis, and Peter Ralph, a professor at University of Southern California (USC), published a recent study of the genetics of...

Scientists Turn To The Phonebook To Name 101 New Beetle Species
2013-03-28 09:33:58

April Flowers for redOrbit.com - Your Universe Online Tropical rainforests are known to harbor a high biodiversity of untold species, many of them unknown and unnamed by scientists as of yet. Insects, especially beetles, make up a large proportion of this undiscovered life on Earth. Experts in remote tropical countries' fauna such as the wilderness of New Guinea, Alexander Riedel of the Natural History Museum Karlsruhe (SMNK) and Michael Balke of the Zoological State Collection Munich...

DNA Used To Quickly Unravel Relationship Between Plants And Insects
2013-03-25 15:54:44

Smithsonian Studying the relationship between plants and the insects that feed on them is an arduous task, as it must be done through direct observation. It can take years for a researcher to fully understand the diets of a community of herbivorous insects in a tropical rain forest. Now, five Smithsonian scientists are paving a fast track using the DNA found inside the insects' stomachs, potentially turning years of research into months. This method will help scientists understand the...

DNA Sequencing Used to Learn The History Of Native Snakes
2013-03-13 09:38:42

George Washington University Alex Pyron´s expertise is in family trees. Who is related to whom, who begat whom, how did they get where they are now. But not for humans: reptiles. In 2011, his fieldwork in Sri Lanka studying snake diversity on the island led him to confirm the identity of 60 known species of snakes. With Sri Lankan collaborators, Ruchira Somaweera, an author on snakes and expert on amphibians and reptiles, and Dushantha Kandambi, a local naturalist and snake expert,...

Taxonomists Beware: The Flowers Might Just Be Fooling Us
2013-03-04 09:54:52

American Journal of Botany Floral morphologies may be less reliable than other traits in determining the relationships of papilionoid species and genera For hundreds of years, plant taxonomists have worked to understand how species are related. Until relatively recently, their only reliable source of information about these relationships was the plants' morphology–traits that could be observed, measured, counted, categorized, and described visually. And paramount among these...

Climate Change And Human Evolution
2013-02-27 07:22:49

Alan McStravick for redOrbit.com - Your Universe Online In a field of study that remains largely in the dark, we have relied on the voice talent of Ray Romano, John Leguizamo and Denis Leary to instruct our children about life in the time of the Ice Age. While the lessons learned aren´t necessarily accurate, one Bournemouth University lecturer on palaeoenvironmental reconstruction and environmental change seemingly thinks it might be a good place to start. Dr. John Stewart,...

Five New Species Of Crustaceans Discovered
2013-02-15 12:32:22

FECYT - Spanish Foundation for Science and Technology Experts from the Centre for Advanced Studies of Blanes and the University of Barcelona (UB) collected and studied different crustacean specimens during recent expeditions to Madagascar, New Caledonia, Vanuatu, the Philippines and French Polynesia. Using morphological and molecular data they have discovered five new species of crustaceans in the waters of these regions. They are genetically different but morphologically very similar...

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...

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...
