Unwelcome Guest Ants Protect Colony From Future Invaders
2013-09-10 06:14:54

April Flowers for redOrbit.com - Your Universe Online Because their loyalty can be bought, mercenary soldiers are notoriously unreliable and may turn against their employers before moving on to the next dirty job. A new report from the Centre for Social Evolution at the Department of Biology, University of Copenhagen, shows that fungus-farming ants are different, however. The study, published in Proceedings of the National Academy of Sciences (PNAS), reports that permanent parasites that...

Researchers Use Insect Antibiotics In Battle Against Bacteria
2013-09-02 10:04:58

Brett Smith for redOrbit.com - Your Universe Online Scientists are locked in an epic struggle with bacteria – with some of the tiny microbes displaying an increased resistance to antibiotics year after year. Researchers at the John Innes Centre (JIC) in Norwich, England are making major strides in the battle against bacteria through their study of stick insects and leafcutter ants, according to a new report to air on the BBC current affairs series Inside Out. “This research is at...

Honeyguide Birds Destroy Their Own Species' Eggs To Eliminate Competition
2013-08-21 09:19:04

University of Cambridge Scientists believe behavior drives evolution of egg size similar to hosts Like cuckoos, honeyguides are parasitic birds that lay their eggs in other birds' nests and dupe them into raising their young. Now scientists reveal that, unlike in cuckoos, the resemblance between honeyguide eggs and those of their bee-eater bird hosts hasn't evolved to trick hosts into accepting the imposter egg as one of their own. Rather, it appears to have evolved to trick other...

A novel study featured in The Journal of Parasitology compared two lakes in the Adirondacks that are only 2.5 kilometers apart. The research showed that significant differences in parasitism can occur, depending on their ecological history. Lawrence, Kansas (PRWEB) August 14, 2013 Every body of water differs in its ecological makeup, species of underwater organisms, and parasitic communities. However, differences in parasitic communities for the same species of native fish in adjacent...

Dragonfly Study Shows How Ecosystem Changes Affect Biodiversity
2013-08-14 07:22:29

April Flowers for redOrbit.com - Your Universe Online Rice University researchers have found that communities in nature are likely to be a lot more sensitive to change than previously thought. The study findings, published in Nature Communications, points to a need for scientists concerned with human impact on the biosphere to take a different look at the consequences of altering the dynamics of a population. One example of such alteration would be removing large members of a species...

Biologist Discovers 33 New Ant Species, Names Some After Mayan Lords And Demons
2013-07-30 08:23:46

University of Utah A University of Utah biologist has identified 33 new species of predatory ants in Central America and the Caribbean, and named about a third of the tiny but monstrous-looking insects after ancient Mayan lords and demons. "These new ant species are the stuff of nightmares" when viewed under a microscope, says entomologist Jack Longino, a professor of biology. "Their faces are broad shields, the eyes reduced to tiny points at the edges and the fierce jaws bristling with...

Betrayal By Bees Could Have Huge Impact On Plant Reproduction
2013-07-23 09:05:30

April Flowers for redOrbit.com - Your Universe Online A new study led by Emory University finds removing even one species of bumblebee from an ecosystem has a swift and clear impact: the floral "sweethearts" of that species produce significantly fewer seeds. The research team focused on the interactions between bumblebees and larkspur wildflowers in Colorado's Rocky Mountains. The findings, to be published by the Proceedings of the National Academy of Sciences, reveal how reduced...

Human-driven Change Good For Parasites But Bad For Birds In Argentine Forests
2013-07-16 14:23:56

Wildlife Conservation Society A new report by the Wildlife Conservation Society (WCS) and the Disease Ecology Laboratory of Instituto de Ciencias Veterinarias del Litoral, Argentina (ICIVET LITORAL, UNL-CONICET) shows that increases in precipitation and changes in vegetative structure in Argentine forests -- factors driven by climate change and deforestation in the region -- are leading to increased parasitism of young nesting birds by fly larvae (botflies) of the species Philornis...

Ants keep a collection of ‘snapshots’ taken close to the nest so they can find their way home from unfamiliar locations. This is the discovery of scientists at The Vision Centre (VC) and the Research School of Biology at the Australian National University, who found that Australian jack jumper ants, just by briefly scanning the panorama, can quickly determine where their nest is from 15 meters away, even from areas that they have never visited before....

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...
