Bull Ants Work Inefficiently At Night
2013-05-28 10:29:12

Brett Smith for redOrbit.com - Your Universe Online Nocturnal Australian bull ants have trouble commuting in the dark, making those that head out and return the most efficient workers, according to a new study that was recently published in the journal PLOS ONE. “To cope with dim or dark environments, night-active ants have larger lenses and wider photoreceptors — to capture light — compared to their day-active relatives,” said co-author Ajay Narendra, at the...

New Species Of Ant From The Philippines Has A Bizarre Pigmentation Pattern
2013-05-22 09:24:53

Pensoft Publishers Scientists discovered a new enigmatic species of ant coming from the Philippines. Cardiocondyla pirata or the pirate ant engages the imagination with a bizarre pigmentation pattern that has no equivalent worldwide. The female castes in the colonies of these species can be recognized by a distinctive dark stripe across the eyes that resembles a pirate eye patch, which inspired the authors to choose the name of the species. The study was published in the open access...

Search And Rescue Robots Could Be Modeled On Ants

[ Watch the Video: Learning Principles of Underground Locomotion From Ants ] Peter Suciu for redOrbit.com — Your Universe Online While ants can spoil a picnic, and fire ants are despised for their painful bites, the tiny creatures are masters at tunneling, and this expertise could be put to good use. Researchers are now looking at how fire ants manage to tunnel quickly through even fine, loose sand in an effort to aid the design of search-and-rescue robots. A team from the...

Crazy Ants Are Now Displacing Fire Ants
2013-05-19 07:17:20

[ Watch the Video: Rise of the Crazy Ants ] redOrbit Staff & Wire Reports - Your Universe Online Residents of the Gulf Coast are in the midst of an invasion - an ant invasion. An invasive and ecologically dominant species of ant is reportedly displacing the native fire ant in areas throughout the southeastern US. The invasive species originates from South America and is known as Nylanderia fulva, or tawny crazy ants, according to Geoffrey Mohan of the Los Angeles Times. Normally...

Ant Colony Evolution And Natural Selection
2013-05-16 08:44:57

April Flowers for redOrbit.com - Your Universe Online City-states in ancient Greece that waited until their own harvest was in before attacking and destroying a rival community´s crops often experienced better long-term success. Ant colonies that show similar selectivity when gathering food have similar results, according to a new study from Stanford University. Deborah M. Gordon, Stanford biology professor, conducted a long-term study of harvester ants. Her findings, published in...

Middle American Stenamma Ant's Peculiar Life History
2013-04-25 21:35:17

Pensoft Publishers Some ant species use clay 'door-pebbles' for the protection of their nest Stenamma is a cryptic "leaf-litter" ant genus that occurs in moderately humid to wet forest habitats throughout the Holarctic region, Central America, and part of northwestern South America (Colombia and Ecuador). The genus was thought to be restricted primarily to the temperate zone, but recent collecting efforts have uncovered a large variety of Neotropical forms, which rival the Holarctic...

Tracking Study Discovers Ants Change Careers As They Age
2013-04-22 09:29:39

Lawrence LeBlond for redOrbit.com - Your Universe Online A single ant colony can have thousands of ants, all scurrying around performing various tasks, maintaining their territory for the queen. And because they all look alike, studying them individually by eye can prove extremely difficult, if not impossible. To bypass this obstacle, Danielle Mersch and colleagues from the University of Lausanne tagged every single worker in entire ant colonies and tracked them by computer. The...

Reproductive Workings Of A Harvester Ant Dynasty Uncovered By Stanford Scientist
2013-02-12 21:08:18

Stanford University For the first time, scientists have measured how successfully a queen ant establishes new colonies. The work by Stanford researchers revealed that the queen was still reproducing several decades after mating. Ants are just about everywhere you look, and yet it's largely unknown how they manage to be so ubiquitous. Scientists have understood the carnal mechanism of ant reproduction, but until now have known little of how successful the daughters of a colony are when...

Social Chromosomes Determine How Many Queen Ants Are In Fire Ant Colony
2013-01-17 13:19:53

Lee Rannals for redOrbit.com — Your Universe Online Researchers wrote in the journal Nature that they discovered a social chromosome in fire ants that explain why some colonies allow for more than one queen ant. Red fire ants live in two different types of colonies, including some that strictly have a single queen, and others that contain hundreds of queens. Scientists discovered that this difference in social organization is determined by a chromosome that carries one of two...

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...

Leafcutter ants are found in warmer regions of Central and South America. These remarkable social insects have evolved an advanced agricultural system. They feed on a specialized fungus that grows only in the underground chambers of the ants' nest. The ants actively cultivate their fungus, feeding it with freshly-cut vegetation and maintaining it free from pests and weeds. This is done by a symbiotic relationship with a colony of bacteria that grows on the ants that protect the fungus. The...

Fire ants are stinging ants of the genus Solenopsis, of which there are 266 species. They include Solenopsis invicta, commonly known as Red imported fire ant (RIFA). Each colony produces large mounds in open areas, and feeds on young plants and seeds. Solenopsis often attacks young animals and can kill them. For humans it has a painful sting - hence the name fire ant - and the aftereffects of the sting are deadly to some individuals. The worker ants are blackish to reddish and vary from...
