Tropical carpenter ants (Camponotus leonardi) live high up in the rainforest canopy. When infected by a parasitic fungus (Ophiocordyceps unilateralis) the behaviour of the ants is dramatically changed. They become erratic and zombie-like, and are manipulated by the fungus into dying at a spot that provides optimal conditions for fungal reproduction. New research, published in BioMed Central's open access journal BMC Ecology, looks at altered behaviour patterns in Zombie ants in Thailand and...

Lichen, those drab, fuzzy growths found on rocks and trees, aren't as cuddly and charismatic as kangaroos or intriguing as opossums, but they could be a fungal equivalent, at least evolutionarily. A Duke research team has found that lichen that seem identical in all outward appearances and produce the same internal chemicals are in fact two different species, one living in North America and one in Australia. They're an example of "convergent evolution," in which two species evolve separately...

But the lichen is so rare it may never be seen again A Philadelphia botanist who has studied rare plants for 50 years, but has never attained the honor of having a plant named for him is finally getting his due, but with a barely visible organism so rare it may never be seen again. Dr. Alfred "Ernie" Schuyler, emeritus curator of botany at the Academy of Natural Sciences and a world expert on rare plants, recently was honored when a colleague discovered a new species of lichen and named it...

A plant's sugary offering betrays caterpillars to predatory ants Trichomes, hair-like projections on leaves, are part of a plant's defense against herbivores: they can be obstacles, traps, or reservoirs for toxic substances. The hairs of wild tobacco Nicotiana attenuata contain primarily acyl sugars, which are composed of the common sugar, sucrose, bound to branched chain aliphatic acids, compounds that give baby vomit its distinctive odor. Tiny, freshly hatched caterpillars consume these...

A species of algae long known to associate with spotted salamanders has been discovered to live inside the cells of developing embryos, say scientists from the U.S. and Canada, who report their findings in this week's Proceedings of the National Academy of Sciences.This is the first known example of a eukaryotic algae living stably inside the cells of any vertebrate."It raises the possibility that more animal/algae symbioses exist that we are not aware of," said Indiana University Bloomington...

MCLEAN, Va., March 9, 2011 /PRNewswire/ -- Delicious and nutritious, shrimp reigns as one of the most popular seafood items throughout the year, particularly during the Lenten season, the 40-day period leading up to Easter when believers from around the world join to abstain from meat and other rich foods. "The Lenten season is actually the largest selling seafood season of the entire year," said Judy Dashiell, Senior Vice President, The Shrimp Council. "Many believers are familiar...

Four new Brazilian species in the genus Ophiocordyceps have been published in the online journal PLoS ONE. The fungi, named by Dr. Harry Evans and Dr. David Hughes, belong to a group of "zombifying" fungi that infect ants and then manipulate their behavior, eventually killing the ants after securing a prime location for spore dispersal. These results appear in a paper by Evans et al. entitled Hidden Diversity Behind the Zombie-Ant Fungus Ophiocordyceps unilateralis: Four New Species Described...

A signature of undiscovered global diversity In an unprecedented coming-out party, 100 newly discovered species are revealed to the world in a single scholarly paper coordinated by Field Museum scientists. The 100 organisms are lichens, a type of fungi that form associations with algae and populate environments from arctic tundra to tropical rain forests. And the usual inattention bestowed upon new lichens is one reason for aggregating so many new ones in a single paper in the Feb. 18 issue...

Leafcutter ants, signature denizens of New World tropical forests, are unique in their ability to harvest fresh leaves to cultivate a nutrient-rich fungus as food. Now, this mutualism -- a complicated interplay of ants, fungi and a suite of bacteria -- is coming into sharper focus as a team of University of Wisconsin-Madison researchers has published the complete genome of the leafcutter ant, Atta cephalotes. The study, published today (Feb. 10, 2011) in the journal Public Library of Science...

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...

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

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...
