Seawater Contains DNA Of Marine Fish And Mammals
2012-08-31 07:49:07

April Flowers for redOrbit.com - Your Universe Online A half liter of seawater can contain evidence of local fish and whale faunas and combat traditional fishing methods, says a new study from the University of Copenhagen. Researchers there have created a new way for monitoring marine biodiversity and resources by using DNA traces in seawater samples. The results of this study are now published in the journal PLoS ONE. "The new DNA-method means that we can keep better track of life...

Why Do Some Younger Animal Families Have More Species Tha Older Families?
2012-08-29 13:30:11

Brett Smith for redOrbit.com - Your Universe Online Basic logic would suggest that the longer a species is around–the more time it has to adapt and evolve, eventually sprouting another whole branch on the tree of life. However, that may not necessarily be the case according to a team of American biologists who just completed an evolutionary survey that accounted for around 1.2 million species. "When we look across the tree of life, the age of the group tells us almost nothing...

One Extinction Leads To Another

redOrbit Staff & Wire Reports - Your Universe Online According to new research, when a carnivore becomes extinct, other predatory species could soon tag along. Other scientists have previously submitted this theory, but a University of Exeter team has now carried out the first experimentation to authenticate it. According to lead researcher Dr Frank van Veen of the University of Exeter's Centre for Ecology and Conservation, "Our experiment provides the first proof of something that...

Neanderthals And Humans - Interbreeding Or Common Ancestry
2012-08-14 07:51:50

April Flowers for redOrbit.com - Your Universe Online A new study from the University of Cambridge finds that the DNA similarities between Neanderthals and modern humans are more likely to have arisen from a shared common ancestor than from interbreeding. Previously, it has been suggested that the shared parts of the genome sequence between the two populations was the result of interbreeding, but the new research, published this week in the journal Proceedings of the National Academy of...

Sea Star Evolution
2012-07-26 14:08:55

How quickly can new species arise? In as little as 6,000 years, according to a study of Australian sea stars. "That's unbelievably fast compared to most organisms," said Rick Grosberg, professor of evolution and ecology at UC Davis and coauthor on the paper published July 18 in the journal Proceedings of the Royal Society B. Grosberg is interested in how new species arise in the ocean. On land, groups of plants and animals can be physically isolated by mountains or rivers and then...

Researchers address great uncertainties in number of species and emphasize the use of technology to accelerate the rate of species discovery Most of the world's species are still unknown to science although many researchers grappled to address the question of how many species there are on Earth over the recent decades. Estimates of non-microbial diversity on Earth provided by researchers range from 2 million to over 50 million species, with great uncertainties in numbers of insects, fungi,...

BPA in rivers leads to breakdown of fish species barriers Hormone-mimicking chemicals released into rivers have been found to impact the mating choices of fish, a new study has revealed. The controversial chemical BPA, which emits oestrogen-like properties, was found to alter an individual's appearance and behavior, leading to inter-species breeding. The study, published in Evolutionary Applications, reveals the threat to biodiversity when the boundaries between species are blurred. The...

Rare Glimpse Shows Origin Of Species

Plant overcomes infertility to give rise to a new species in Scotland A new species of monkey flower, created by the union of two foreign plant species, has been discovered on the bank of a stream in Scotland. Genetic changes in this attractive yellow-flowered hybrid have allowed it to overcome infertility and made it a rare example of a brand new species that has originated in the wild in the last 150 years. Thousands of wild species and some crops are thought to have originated in this...

Lee Rannals for redOrbit.com - Your Universe Online Research has revealed just what is behind a birds' song, shedding more light on nature's melody. Canadian researchers found that closely related birds that share the same habitat are not necessarily birds of the same feather that flock together in music, but instead tend to look and sound different. The team studied 250 bird species throughout the world and were able to compile a database of where the birds lived, and what they...

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...
