Kristen Kusek, Harvard University New genome editing tool offers strategy to manage insect-borne disease A cross-disciplinary team is calling for public discussion about a potential new way to solve longstanding global ecological problems by using an emerging technology called “gene drives.” The advance could potentially lead to powerful new ways of combating malaria and other insect-borne diseases, controlling invasive species and promoting sustainable agriculture. Representing...

Monkeys Have Undergone Evolution In Facial Appearance To Avoid Interbreeding
2014-06-27 03:34:36

New York University Old World monkeys have undergone a remarkable evolution in facial appearance as a way of avoiding interbreeding with closely related and geographically proximate species, researchers from New York University and the University of Exeter have found. Their research provides the best evidence to date for the role of visual cues as a barrier to breeding across species. "Evolution produces adaptations that help animals thrive in a particular environment, and over time...

University of Massachusetts at Amherst A new study of how biodiversity arises shows how a mutation in a single gene during development can lead to different consequences not only in jaw shape, but how this leads to different feeding strategies to exploit different ecological niches A new study of how biodiversity arises, by evolutionary biologists at the University of Massachusetts Amherst, shows how a mutation in a single gene during development can lead to different consequences not...

KU Leuven A team of Belgian biologists led by researchers at KU Leuven has provided the first genetic evidence that rapid evolution can help non-native plant species spread in new environments. Using samples of centuries-old herbaria and DNA analysis, the researchers reconstructed the genetic adaptations undergone by the Pyrenean rocket prior to its rapid spread in Belgium. The Pyrenean rocket (Sisymbrium austriacum subsp. Chrysanthum) is a plant that grows in the mountains of southern...

Researchers Remap The Epic Evolution Of A 'Ring Species'
2014-05-26 03:58:52

University of British Columbia The Greenish Warbler, long considered an idealized example of a single species that diverged into two as it expanded its range, has a much more checkered family history than biologists previously realized. Ring species are a continuous loop of related populations, each adapted to its local environment, with two terminal populations in the loop meeting but now unable to mate. But an in-depth genomic analysis published today in Nature by University of...

diamondback terrapin

April Flowers for redOrbit.com - Your Universe Online There is an old saying that one should never judge a book by its cover, and that seems to be true for turtles as well. This diamondback terrapin is known for the diverse patterns intricately grooved into its shell. The pattern makes the turtle instantly recognizable, however it does not solve the problem of conservation for these coastal animals. That answer, according to a new study from the United States Geological Survey (USGS), is...

redOrbit Staff & Wire Reports - Your Universe Online Researchers from Arizona State University and Plymouth University in the UK are advocating changes to the way in which threatened species are identified, due to the potential danger presented to vulnerable animal populations by the so-called “gold standard” of collecting voucher specimens for identification purposes. Ordinarily, field biologists traditionally collect those specimens to distinguish animals and/or confirm that...

Genetic Distinctness To Guide Global Bird Conservation
2014-04-11 12:08:15

Cell Press In the midst of today's global extinction crisis, decisions about conservation should include prioritizing how best to preserve as much of the tree of life as possible. So say researchers who report in the Cell Press journal Current Biology on the first application of an approach to identify the most evolutionarily distinct of the world's 9,993 bird species. At the very top of their list of the most evolutionary distinct birds is the South American oilbird, which represents...

Deciding How Many Species You Have
2014-04-03 10:41:29

Pensoft Publishers It is often difficult to decide whether two animals belong to the same or two distinct species. This can be especially challenging for animals which externally look very similar. In a recent study, published in the open access journal Zoosystematics and Evolution, scientists from the Museum für Naturkunde Berlin use genetic data and sound analysis to test if treefrogs from West and Central Africa belong to different or the same species. Due to the fact that, when...

Scientists Identify Factors Limiting Hybridization Of Closely-related Woodrat Species
2014-03-31 08:41:24

Wildlife Conservation Society A pair of new studies from the Wildlife Conservation Society, Idaho State University, and the University of Nevada Reno look at the surprising variety of factors that prevent two closely related species of woodrats from becoming a single hybrid species despite the existence of hybrid individuals where the two species come into contact. After finding that two closely related species, the desert and Bryant's woodrats, could interbreed and produce hybrid...

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...
