Worms infecting fish grow 4 times faster at higher temperatures and manipulate the behavior of fish Parasitic worms that infect fish, and have a devastating effect on fish reproduction, grow four times faster at higher temperatures — providing some of the first evidence that global warming affects the interactions between parasites and their hosts. The study from the University of Leicester revealed that global warming had the potential to change the balance between parasite and...

Researchers have confirmed a unique behavior within the male population of tiny fig wasps that pollinate fig trees — they team up to help pregnant females, even if they have not mated themselves. Published online in the Royal Society journal Biology Letters, the study confirms that placid male pollinator fig wasps work together to chew an escape tunnel for their females, before crawling back into the fig to die - the non-pollinating variety are too busy fighting each other to help....

A co-evolutionary arms race exists between social insects and their parasites. Army ants (Leptogenys distinguenda) share their nests with several parasites such as beetles, snails and spiders. They also share their food with the kleptoparasitic silverfish (Malayatelura ponerophila). New research published in BioMed Central's open access journal BMC Ecology shows that the silverfish manage to hide amongst the ants by covering themselves in the ant's chemical scent. Myrmecophilous...

Laser capture microdissection provides an insight into the symbiotic program of root cells Not only mineral oil and petroleum gas, also phosphorous is a scarce resource. According to well-respected scientists who gathered together for a conference in Cambridge this August, we will face significant problems relating to phosphorous deficiency in just 20 years from now. Phosphorous, this important and essential mineral, is part of our DNA and, therefore, irreplaceable. Many soils are already...

Smelly Ants Invade Hawaii
2011-11-02 04:30:28

A common pest in the mainland United States known for its tropical smell now has a tropical habitat to go along with it. Odorous house ants - so called because they tend to invade houses and smell like coconut when smashed - have found their way to Hawaii. And, according to Purdue University entomologist Grzegorz Buczkowski, it doesn't seem as though they have plans to end their vacations. "Odorous house ants in Hawaii are not like they are here in natural areas where they live in small...

A team of researchers from the Hawai'i Institute of Marine Biology (HIMB) have developed an interactive global map of corals and zooxanthellae as part of a hybrid web application titled GeoSymbio. This application provides global-scale biological and ecosystem information on symbiotic zooxanthellae called Symbiodinium which are uni-cellular, photosynthetic dinoflagellates that live inside the cells of other marine organisms like anemones, jellyfish, and corals. Symbiodinium are responsible...

Coral reefs are among the most diverse ecosystems on the planet, second only to tropical rain forests. Bird's nest coral (Seriatopora hystrix) is common throughout the Indo-Pacific and is able to live across a range of depths. However, there is little gene flow between the coral populations at each depth and even the algal endosymbionts (Symbiodinium), which provide energy for the corals to survive, are genetically different across habitats. New research published in BioMed Central's open...

Mob Tactics Help Vicious Queen Ants To Reach The Top

Leptothorax acervorum ants live all over the Northern hemisphere, but their reproductive strategy depends on habitat. Colonies are polygynous (more than one queen) in the forest of Siberia and central Europe, but functionally monogynous (only one queen reproduces) on sun-exposed slopes in Alaska, Hokkaido and the mountains of central Spain. New research published in BioMed Central's open access journal BMC Ecology demonstrates that when a colony is functionally monogynous not only do queen...

  Captive breeding could transform the saltwater aquarium trade and save coral reefs Marine biologists at The University of Texas at Austin Marine Science Institute are developing means to efficiently breed saltwater aquarium fish, seahorses, plankton and invertebrates in captivity in order to preserve the biologically rich ecosystems of the world's coral reefs. These scientists believe their efforts, and those of colleagues around the world, could help shift much of the $1...

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...

toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
