Scientists have discovered two viruses that appear to infect the single-celled microalgae that reside in corals and are important for coral growth and health, and they say the viruses could play a role in the serious decline of coral ecosystems around the world. These viruses, including an RNA virus never before isolated from a coral, have been shown for the first time to clearly be associated with these microalgae called Symbiodinium. If it's proven that they are infecting those algae and...

World's Smallest Flies Decapitate Tiny Ants
2012-07-02 08:25:50

The smallest fly ever discovered is just 0.40 millimeters in length, and is a member of a fly family that is known for 'decapitating' ants A new species of phorid fly from Thailand is the smallest fly ever discovered. At just 0.40 millimeters in length, it is 15 times smaller than a house fly and five times smaller than a fruit fly. The tiny fly, Euryplatea nanaknihali, is also the first of its genus to be discovered in Asia, and it belongs to a fly family (Phoridae) that is known for...

Root Aphid Cloned By Ant Farms In Subterranean Rooms
2012-07-02 08:21:28

The yellow meadow ant, Lasius flavus, farms root aphids for sugar (honeydew) and nitrogen (protein). In turn these species of aphids have developed distinctive traits never found in free living species such as the 'trophobiotic organ' to hold honey dew for the ants. New research published in BioMed Central's open access journal BMC Evolutionary Biology shows that over half of ant mounds contained only one of the three most common species of aphid, and two thirds of these has a single aphid...

Mathematicians at the University of York in the UK and the University of Canterbury in New Zealand say they have disproved a widely accepted theory underpinning the operation of complex networks of interactions in the natural world. Networks are a powerful way to describe ecological communities, which typically involve large numbers of species that can exhibit both negative (e.g. competition or predation) and positive (e.g. mutualism) interactions with one another. Recent mathematical and...

The Highly Diverse Ant Fauna Of The Philippines
2012-06-19 11:13:31

Intensive field work by researchers David General of the Palawan State University, The Philippines and Gary Alpert of the Museum of Comparative Zoology, Harvard University has led to the discovery of nine genera of ants that had never been recorded before in the Philippines. Another two new genera were discovered by other researchers in a remote mountain region. The study was published as the 200th jubilee issue of the open access journal Zookeys. About 30% of all currently known ant...

Older Male Ants Single Out Younger Rivals For Death Squad
2012-06-15 08:34:14

Male Cardiocondyla obscurior ants are diphenic (either winged or wingless). New research published in BioMed Central's open access journal BMC Ecology demonstrates that the dominant wingless (ergatoid) male is able to identify potential rivals before they emerge from their pupae. Constant patrolling of the nest ensures that this male is able to bite or chemically tag rivals as soon as they emerge from their pupae. Chemically tagged ants are quickly destroyed by workers. When ants emerge...

AntWeb To Catalogue Ant Species In 3D
2012-06-11 09:05:46

Brett Smith for redOrbit.com A biologist from the California Academy of Sciences is leading the effort to create an online catalogue of ant species in the form of high resolution, three dimensional images. In building the catalogue, Brian Fisher, the self-described “ant guy”, and his team have been creating high definition mosaics of every ant species they could get their hands on. After starting the database with 8,000 species in the U.S., the team has kicked off their...

Research at Carlos III University (Universidad Carlos III) in Madrid (Universidad Carlos III - UC3M) is developing an algorithm, based on ants´ behavior when they are searching for food, which accelerates the search for relationships among elements that are present in social networks. One of the main technical questions in the field of social networks, whose use is becoming more and more generalized, consists in locating the chain of reference that leads from one person to another,...

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...

Image Caption: Amphiprion polymnus at Tasik Ria House reef, North Sulawesi, Indonesia. 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...
