#Zombie Ants Controlled by Four New Species of Fungi A stalk of the newfound fungus species Ophiocordyceps camponoti-balzani,
the fungus is actually four distinct species#ll of which can mind control#ants#cientists announced last week.
pics) The fungus species can infect an ant, take over its brain, and then kill the insect once it moves to a location ideal for the fungi to grow
and spread their spores. All four known fungi species live in Brazils Atlantic rain forest, which is rapidly changing due to climate change
and deforestation, said study leader David Hughes, an entomologist at Penn State university. Hughes and colleagues made the discovery after noticing a wide diversity of fungal growths emerging from ant victims,
It is tempting to speculate that each species of fungus has its own ant species that it is adapted best to attack#
This potentially means thousands of zombie fungi in tropical forests across the globe await discovery, #he said.
The four newly identified zombie#fungi species use different techniques to spread after infecting an ant, the researchers found.
Some of the fungi species create thin infection pegs#that stick out from a victims body
Other fungus species develop explosive spores on infected ants bodies. When other ants come near the cadavers,
the fungi species direct#the dying ants to anchor themselves to leaves or other stable places,
as pictured above#roviding a stable nursery#for the fungus. For instance, as the Ophiocordyceps camponoti-balzani fungus is about to kill the ant, the insect bites down hard into whatever substance its standing on.
This attachment is so strong that a dead zombie ant can remain stationary even when hanging upside down,
A white fungus stalk (left) of the Ophiocordyceps camponoti-rufipedis species begins to poke through the head of a zombie ant two days after death.
the fungus rapidly spreads through the body. During the first couple days, though, very little evidence of the fungus is visible from the outside.
During later stages of Ophiocordyceps camponoti-rufipedis infection, the fungus rapidly consumes the nutrients inside a zombie ant
and begins to colonize the outside of the ants body. The fungus stalk growing from the back of the head also becomes longer and more noticeable.
The mature fungus stalk, shown growing from a zombie ants head during the final stage of infection,
differs among fungi species. For instance, Ophiocordyceps camponoti-rufipedis creates just a single stalk (pictured), while Ophiocordyceps camponoti-balzani forms a forked stalk.
Ants arent the only zombie-fungi hosts#ther insects also fall prey to fungus. Above, a wasp is infected by a Cordyceps fungus species that hasnt yet been named or formally documented.
Fungi of the Cordyceps genus are the products of a tightly evolved arms race between hosts
and parasites, study author Hughes noted. That means the fungi are locked often into one type of host#specialization that might spell doom for fungi species as host species die out.
Unlike ants, many insect species that fall victim to zombie fungi are very difficult to identify after the fungus has spread around their bodies the scientists noted.
Overall fungi help keep nature working smoothly, Hughes added. They may be less cuddly than pandas#but for the overall health of the planet,
fungi are inestimably more important.##Crickets too can fall prey to zombie fungi (as pictured),
though little is known about the fungus species that brought this insect to its horrific end.
Hughes plans to remedy that#nd expects to find many more zombie fungus species in the forests of Brazil.

That's just one of the symbolic connections between the Amanita muscaria mushroom and the iconography of Christmas according to several historians and ethnomycologists or people who study fungi's influence on human societies.
History of Magic Mushrooms & Other Hallucinogens In his book Mushrooms and Mankind (The Book Tree 2003) the late author James Arthur points out that Amanita muscaria also known as fly agaric lives throughout the Northern hemisphere under conifers
and birch trees with which the fungi which are deep red with white flecks have a symbiotic relationship.

It is because underneath the pine bough is the exact location where one would find this'Most Sacred'substance the Amanita muscaria in the wild.
and Northern europe and seek out these hallucinogenic fungi as the area's human inhabitants have also been known to do.
Donald Pfister a Harvard university biologist who studies fungi suggests that Siberian tribesmen who ingested fly agaric may have hallucinated that the grazing reindeer were flying.
Tree ornaments shaped like Amanita mushrooms and other depictions of the fungi are also prevalent in Christmas decorations throughout the world particularly in Scandinavia
and Northern europe Pfister pointed out. That said Pfister made it clear that the connection between modern-day Christmas

An international team of molecular biologists studied the historical spread of Phytophthora infestans a funguslike organism that devastated potato crops and led to the famine in Ireland.
Fascinating Fungi Previously a Phytophthora strain called US-1 was thought to have triggered the potato famine
In fact the DNA quality was so good the researchers were able to sequence the entire genome of Phytophthora infestans and its host the potato within just a few weeks.
The decoded genomes of these historical samples were compared then with modern Phytophthora strains from Europe Africa and The americas.
According to the study Phytophthora infestans originated in Mexico's Toluca Valley. When Europeans and Americans first came to Mexico in the 16th century the pathogen experienced increased genetic diversity
and in the early 1800s the HERB-1 Phytophthora strain emerged and was brought out of Mexico the researchers said.
In the 20th century as new varieties of potatoes were introduced the HERB-1 strain was replaced eventually by the US-1 Phytophthora strain the researchers said.
