Food Web Affected By Parasites More Than You Think
2013-06-19 10:15:07

University of California - Santa Barbara Parasites are ubiquitous. They feed on virtually every animal and even on each other. Yet, for all the parasites' collective contributions to biomass and biodiversity, conventional food webs don't account for the presence of these tiny and numerous consumers. A recent study featuring work by several UC Santa Barbara scientists focuses on the impact parasites have on food webs, with findings that are expected to alter our picture of who-eats-who. The...

Parasites comprise a large proportion of the diversity of species in every ecosystem. Despite this, they are rarely included in analyses or models of food webs. If parasites play different roles from other predators and prey, however, their inclusion could fundamentally alter our understanding of how food webs are organized. In a paper published 11 June in the open access journal PLOS Biology, Santa Fe Institute Professor Jennifer Dunne and her team test this assertion and show that including...

Groundbreaking developments expand range of safe applications designed to inhibit contact between mosquitoes and humans. Riverside, CA (PRWEB) June 03, 2013 Olfactor Laboratories, Inc. (OLI), an ieCrowd company, filed for three new patents relating to the company´s cutting-edge drive to develop products derived from its patent-pending compounds capable of disrupting insects´ CO2 receptors — thereby inhibiting mosquitoes´ ability to detect humans. The three new patent...

Mosquitoes Lose Their Sense Of Smell After Genetic Mutations
2013-05-30 05:45:43

April Flowers for redOrbit.com - Your Universe Online Researchers at the Howard Hughes Medical Institute (HHMI) have altered the way insects respond to odors, including the smell of humans and the insect repellant DEET, in one of the first successful attempts at genetically engineering mosquitoes. The findings, published in an issue of Nature, demonstrates that mosquitoes can be genetically manipulated using the latest research techniques. The results also pave the way to understanding...

Behavior Of Mosquitos May Be Immune Response, Not Parasite Manipulation
2013-05-22 14:30:43

Penn State Malaria-carrying mosquitos appear to be manipulated by the parasites they carry, but this manipulation may simply be part of the mosquitos' immune response, according to Penn State entomologists. "Normally, after a female mosquito ingests a blood meal, she matures her eggs and does not take another one until the meal is digested," said Lauren J. Cator, postdoctoral fellow in entomology and a member of the Center for Infectious Disease Dynamics, Penn State. "If infected,...

Mosquitoes can put a damper on the summer time, but Horne´s Pest Control Company offers information and advice for dealing with the biting pest. Martinez, GA (PRWEB) May 21, 2013 Mosquitoes are always an issue in the summer months, and in some ways seem to be getting worse. Some entomologists believe, that as a result of global warming, diseases carried by insects will continue to increase. It is believed that since the beginning of time - mosquitoes are responsible for more human...

Malarial parasite may change mosquito olfactory system, enhance attraction to human odor Mosquitoes infected with the malarial parasite Plasmodium falciparum are significantly more attracted to human odors than uninfected mosquitoes, according to research published May 15 in the open access journal PLOS ONE by James Logan and colleagues from the London School of Hygiene & Tropical Medicine, UK. The authors investigated the response of mosquitoes infected with P. falciparum malaria...

Pork Tapeworm, Taenia solium
2014-01-12 00:00:00

The pork tapeworm (Taenia solium), also known simply as a tapeworm, is a species of parasitic worm that is classified within the Platyhelminthes phylum. This species infects pigs and humans in many areas of the world including Africa, Southern Europe, Asia, South America, and some areas of North America. This species can cause cysticercosis in its larval stage, which is one of the major causes of seizures in humans. The pork tapeworm can reach an average body length between 2 to 3 meters, but...

Paragonimus westermani
2014-01-12 00:00:00

Paragonimus westermani is a species of fluke, or flatworm that is classified within the Platyhelminthes phylum. This species is abundant in South America and Asia and affects the lungs of humans and other hosts. It was first discovered in 1878 in Europe after two Bengal tigers died. In 1879, Ringer found this species in the lungs of a human. Manson and Erwin von Baelz identified the sputum and eggs separately in 1880, after which Manson asserted that a snail was most likely the worm's...

Echinococcus multilocularis
2014-01-12 00:00:00

Echinococcus multilocularis is a species of tapeworm that is classified within the Platyhelminthes phylum. It is one of a few worms that cause echinococcosis, a disease that affects many canid species including wolves, coyotes, foxes, jackals, domesticated dogs. Humans can also contract this disease. Adult members of this species can reach an average length of .2 inches, and like other species of tapeworm, its body is segmented by three proglottids. Its head, or scolex, is equipped with...

Trichinella spiralis
2014-01-12 00:00:00

Trichinella spiralis, sometimes known as the pork worm, is a parasite within the Nematoda class. It can be found in pigs, rats, humans, and bears. This worm causes trichinosis in humans, most often from consuming undercooked pork. This species is the smallest within its class, reaching an average body length of .16 centimeters. Females are twice as large as males, displaying a sexual dimorphism. The reproductive organs of females are unique to the species in that the front end holds developed...

Guinea Worm, Dracunculus medinensis
2014-01-12 00:00:00

The Guinea worm (Dracunculus medinensis) is a species of roundworm with the Nematoda phylum. This species is once ranged throughout Asia and Africa, including the west coasts of Africa in Guinea. Although it is not present in this range anymore, the species retains its common name. It was identified in this area by Carl Linnaeus, who discovered the parasite in many merchants along the coast. Its scientific name was also given due to a large population in one area, called Medina. Dracunculus...
