Ant Slave Rebellion
2012-09-26 19:13:14

Michael Harper for redOrbit.com — Your Universe Online There´s new evidence today ants that have been captured and made slaves by other ants aren´t simply taking their plights lying down. According to a new study, these slave ants are prone to try and take down their oppressors by sabotaging their families. The first signs of this kind of ant rebellion were noted by Johannes Gutenberg University Mainz (JGU) research professor Dr. Susanne Foitzik in 2009. However, in the...

Collective decision-making proves more efficient than individual selection Scientists at Arizona State University have discovered that ants utilize a strategy to handle "information overload." Temnothorax rugatulus ants, commonly found living in rock crevices in the Southwest, place the burden of making complicated decisions on the backs of the entire colony, rather than on an individual ant. In a study published in the early, online version of scientific journal Current Biology,...

In relationships based on mutuality, the number of individuals involved can determine the rate at which species evolve The relationship between species determines how rapidly they evolve. Parasites and their hosts coevolve more rapidly, and partners in a mutualistic relationship can evolve more slowly. But this view is obviously too simplistic. The rate of evolution in a mutualistic relationship does not depend only on the type of interactions, but also on the number of individuals...

Marine Microbes Engage In Unusual Symbiosis
2012-09-22 09:56:42

April Flowers for redOrbit.com - Your Universe Online A study published in this week's issue of Science shows how tiny, single-celled algae and a highly specialized bacteria have formed a partnership that helps keep the ocean fertilized.  This symbiotic pair takes nitrogen from the atmosphere and "fixes" it into a form that other organisms can use. The results of the study emerged from the investigation of a mysterious nitrogen-fixing microbe that has a very small genome. ...

DNA Analysis Can Help In Classifying Single-celled Algae
2012-09-20 12:28:58

For nearly 260 years -- since Carl Linnaeus developed his system of naming plants and animals -- researchers classified species based on visual attributes like color, shape and size. In the past few decades, researchers found that sequencing DNA can more accurately identify species. A group of single-celled algae -- Symbiodinum -- that live inside corals and are critical to their survival -- are only now being separated into species using DNA analysis, according to biologists....

The Borderea chouardii plant, which is critically endangered and is found only on two adjacent cliff sides in the Pyrenees, employs a unique and risky doubly mutualistic reproductive strategy with local ants, according to research published Sep. 12 in the open access journal PLOS ONE. The researchers, led by Maria Garcia of the Pyrenean Institute of Ecology (CSIC), found that two ant species acted as the main pollinators for the plant, while a third species dispersed seeds. About a third...

John Neumann for redOrbit.com — Your Universe Online Researchers have long known that ants live in some of the most complex social structures of any animal. With the division of labor and communication between individual ants and the ability to solve complex problems, the reason for such complex structures may be the increased number of smells that ants can discern. A team of scientists, led by Lawrence Zwiebel and his research team at Vanderbilt, recently completed the first full...

Bees Are Still Stressed, Need Our Help
2012-09-07 04:13:26

Brett Smith for redOrbit.com - Your Universe Online Agricultural yields have always depended on pollinators and their symbiotic ability to spread the powdery substance necessary for plant reproduction, a fact that has become more important as the unexplained drop in the worldwide bee population continues. Pollinating insects add to the production of 84 percent of European crops and officials there are looking to boost the efforts of domesticated pollinators, such as honeybees, and wild...

Sebae Clownfish, Amphiprion sebae
2013-02-17 07:52:18

Image Credit: Miles Wu/Wikipedia (CC BY-SA 2.0) The sabae clownfish is a very rare species in the wild and is aggressive, especially as it matures. It is found in the northern Indian Ocean around India, Sri Lanka, Arabian Peninsula, Andaman Islands, Sumatra, Indonesia, and the Maldive Islands. This fish inhabits lagoons and coastal waters around reefs, at a depth range of 6 - 75 feet. This species of fish is the most popular fish for home aquariums. The body of the sabae clownfish is...

Credit: Jens Peterson/Wikipedia (CC BY-SA 3.0) Saddleback clownfish are found in harbors and lagoons with a soft or sandy bottom, around reefs at depths from 6 - 90 feet. This fish is native to the Western Pacific, around China, Viet Nam, Gulf of Thailand, Indonesia, Philippines, northern Australia, New Guinea, New Britain, and the Solomon Islands. The body of the saddleback clownfish ranges in color...

Convict Blenny, Pholidichthys leucotaenia
2013-01-03 15:48:38

The convict blenny lives in tunnels around coastal reefs and in shallow lagoons of the Western South Pacific, mainly from the Philippines to the Solomon Islands. The young of this fish will often swim in schools around the reef heads and ledges so tightly packed together they will look like one organism. This species, sometimes called a blenny and sometimes called a goby, actually it is neither. It is in a classification alone with one other species called a worm blenny. The convict blenny...

The Polydnaviruses (PDV) are a family of insect viruses that contain two genera: Ichnoviruses (IV) and Bracoviruses (BV). The ichnoviruses occur in ichneumonid wasps and bracoviruses in braconid wasps. The virus is composed of multiple segments of double-stranded superhelical DNA packaged in capsid proteins and a double layer or single layer envelope. The full genome of the virus is integrated into the genome of the wasps and the virus only replicates in specific cells in the female...

The ants, one of the most successful groups of insects, are of particular interest because they form advanced colonies, and can constitute up to 15 percent of the total animal biomass of a tropical rainforest. They belong to the order Hymenoptera and are close relatives of the vespoid wasps. Ants appear in amber, found in central New Jersey, believed to be from the Cretaceous period. It is thought that they evolved from the wasps that had appeared during the Jurassic period. They are...
