Humans are often infected by parasites, sometimes even several species at a time. Such co-infections are more difficult to treat if the parasites interact with each other. An ecologist from the University of Zurich and his international team have compiled a list of the numerous possibilities as to how parasites can interact: They are most likely to do so indirectly via the food source they share. Over 1,400 species of parasites – viruses, bacteria, fungi, intestinal worms and protozoa...

Jumping Spider Uses Ant As Bodyguard
2014-03-12 09:31:54

Springer Ants are the unlikely guardians of jumping spiders in their battle against aggressive spitting spiders A timid jumping spider uses the scent of ants as a secret weapon to save itself from becoming the somewhat soggy prey of the predatory spitting spider. The downside to this plan is that jumping spiders are also a favorite snack of its very own saviors. To overcome this additional hazard, the spider has made yet another plan in the form of an ant-proof nest, writes Ximena...

Worker Ants Link Bodies And Buoyant Broods To Protect Queen During Flood
2014-02-20 09:34:12

PLOS When facing a flood, ants build rafts and use both the buoyancy of the brood and the recovery ability of workers to minimize injury or death, according to a study published in PLOS ONE on February 19, 2014 by Jessica Purcell from University of Lausanne, Switzerland, and colleagues. Furthermore, the queen ant is placed in the middle and protected on all sides by the rafting ants. When put in harm's way, social animals are often able to work together to enhance the survival and...

Fire Ants Being Displaced By Venom-Neutralizing Crazy Ants
2014-02-14 07:08:22

[ Watch the Video: Crazy Ants Attack Fire Ants ] April Flowers for redOrbit.com - Your Universe Online In areas across the southeastern United States, invasive "crazy ants" are rapidly displacing fire ants by secreting a compound that neutralizes the fire ant's venom, according to a new study from The University of Texas at Austin. The crazy ant is the first known example of an insect with the ability to detoxify another insect's venom. The latest in a wave of ant invasions from the...

Ants Depend On A Tiny Neck Joint To Do Heavy Lifting: Study
2014-02-11 08:34:20

[ Watch the Video: Neck Joint The Key To An Ant's Strength ] April Flowers for redOrbit.com - Your Universe Online We have known and celebrated the strength of the tiny ant, but never really understood how it was achieved, until now. A new study from Ohio State University, published in the Journal of Biomechanics, reveals that the real secret to the ant's legendary strength may lie in its tiny neck joint. The findings show that the neck joint of a common American field ant can...

Microcosm Of Biodiversity In New Plant Species
2014-02-10 10:21:53

Pensoft Publishers Biologists working in the Andes mountains of Ecuador have described a new plant species, a wild relative of black pepper, that is in itself a mini biodiversity hotspot. The new species, Piper kelleyi, is the sole home of an estimated 40-50 insect species, most of which are entirely dependent on this plant species for survival. This discovery is part of a larger project which focuses on the influence of plant-produced chemical compounds on biodiversity. The study was...

GUELPH, ON, Jan. 30, 2014 /CNW/ - Syngenta Canada Inc. and Dalhousie University, together with the Natural Sciences and Engineering Research Council of Canada, are partnering on an innovative research project to increase bee populations and blueberry yields in the Maritime Provinces. Canada is the world's largest producer of wild blueberries and most are grown in Quebec and in the Atlantic provinces. They are important economically and are part of our cultural identity. "An...

How Gene Expression Differs Between Castes In Ants
2014-01-30 11:53:06

Johannes Gutenberg University Mainz Novel or highly modified genes play a major role in the development of the different castes within ant colonies. Evolutionary biologists at Johannes Gutenberg University Mainz (JGU) came to this conclusion in a recent gene expression study. Dr. Barbara Feldmeyer and her colleagues at the JGU Institute of Zoology studied the question how the different female castes arise. An ant colony generally consists of a queen and the workers. Moreover, workers can...

Acacia Plants Protected Against Pathogens By Ants
2014-01-16 10:19:05

Max Planck Institute for Chemical Ecology Researchers discover an additional level of this insect-plant symbiosis The biological term “symbiosis” refers to what economists and politicians usually call a win-win situation: a relationship between two partners which is beneficial to both. The mutualistic association between acacia plants and the ants that live on them is an excellent example: The plants provide food and accommodation in the form of food bodies and nectar as well as...

Scientists Discover New Slave-making Ant Species From Eastern US
2014-01-10 06:37:59

Pensoft Publishers A group of scientists from the University of Mainz and the Senckenberg Museum of Natural History Goerlitz, headed by Susanne Foitzik and Bernhard Seifert, recently described a new slave-making ant species from the eastern USA. They baptized the new ant Temnothorax pilagens – from pilere (Latin): to pluck, plunder or pillage. The paper was published in the open access journal ZooKeys. In contrast to the famous slave-hunting Amazon Ants whose campaigns may include up...

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...

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...
