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,...

Increases in the diversity of parasites that attack amphibians cause a decrease in the infection success rate of virulent parasites, including one that causes malformed limbs and premature death, says a new University of Colorado Boulder study. According to CU-Boulder Assistant Professor Pieter Johnson, scientists are concerned about how changes in biodiversity affect the risk of infectious diseases in humans and wildlife. Charting the relationships between parasites and amphibians is...

New research shows how bacteria evolve to increase ecosystem functioning by recycling each others waste. The study provides some of the first evidence for how interactions between species shape evolution when there is a diverse community. Predicting how species and ecosystems will respond to new environments is an important task for biology. However, most studies of evolutionary adaptation have considered single species in isolation, despite the fact that all species live in diverse...

Ancient plants grown in state-of-the-art growth chambers recreating environmental conditions from more than 400 million years ago have shown scientists from the University of Sheffield how soil dwelling fungi played a crucial role in the evolution of plants. This ground breaking work provides fundamental knowledge of how plants colonized the land before roots evolved and the co-evolution of one of the most ancient relationships, between fungi and early plants that played a founding role in...

The Zombie-Ant Fungus Is Under Attack, Research Reveals
2012-05-03 06:23:50

A parasite that fights the zombie-ant fungus has yielded some of its secrets to an international research team led by David Hughes of Penn State University. The research reveals, for the first time, how an entire ant colony is able to survive infestations by the zombie-ant fungus, which invades an ant's brain and causes it to march to its death at a mass grave near the ant colony, where the fungus spores erupt out of the ant's head. "In a case where biology is stranger than fiction, the...

As a part of the effort, a Homeowner Rebate, Parent Tool Kit...

Invasion Of The Oversized Crustaceans! Asian Tiger Shrimp Invade The US
2012-04-27 07:16:15

Giant cannibal shrimp are invading the coasts of America en masse -- and while it sounds like the work of a mad scientist in one of those cheesy, low-budget, black-and-white 1950s science-fiction movies, the danger (or rather, lack thereof) is all too real. U.S. Geological Survey (USGS) and National Oceanic and Atmospheric Administration (NOAA) researchers have discovered that there were more than 10 times as many sightings of Asian tiger shrimp, which can grow to be more than a foot long...

In a study published in the journal Proceedings of the National Academy of Science, scientists from the Max Planck Institute for Marine Microbiology in Bremen and Greifswald University, together with colleagues from Freiburg, Italy and the USA, have revealed that a small marine worm, faced with a scarce food supply in the sandy sediments it lives in off the coast of Elba, must deal with a highly poisionous menu: this worm lives on carbon monoxide and hydrogen sulphide. The worm, Olavius...

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...

Saddleback Clownfish, Amphiprion polymnus

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...
