Pesticides choke pathway for nature to produce nitrogen for crops

...s is the mechanism by which these chemicals reduce symbiosis and nitrogen fixation." Fox began the project as a doctoral student with John A. McLachlan, director of the Center for Bioenvironmental Research at Tulane University. She is working at the University of Oregon as a National Institutes of Health an...

Corals that can fight global warming may one day help fragile reefs

... The complexities arise from different levels of symbiosis within a coral, both with bacteria on the surface and algae in the interior. Moreover, the warmer waters cause increased virulence of some pathogens as well as a diminished ability of corals to fight them. But these complications can also be keys to ...

Ocean sampling yields environmental sources of coral symbionts

...organisms that reef corals need for survival. The symbiosis between special algal species and reef corals is t...mplex ecosystem, but our understanding of how this symbiosis is established by new corals has been limited by the fact that the symbiotic algae are difficult to ...

Extraordinary life found around deep-sea gas seeps

...ps support unique communities of animals living in symbiosis with microbes that can convert these energy-rich chemicals to living matter (a form of 'chemosynthesis') in the absence of sunlight. New Zealand is one of the few places in the world where at least four types of chemosynthetic habitats occur in cl...

Health of coral reefs detected from orbit

...l bleaching happens when symbiotic algae living in symbiosis with living coral polyps (and providing them their distinctive colours) are expelled. The whitening coral may die with subsequent impacts on the reef ecosystem, and thus fisheries, regional tourism and coastal protection. Coral bleaching is linked to...

Digging in the dirt for life's biochemical foundations

...echanism is important for entire plants growing in symbiosis [partnership] with the fungi in soil, where other nitrogen sources may be more easily available," Fitter says. "Moving to the field is always difficult but rewarding." Related sites Shachar-Hill faculty Web page: http://www.plantbiology.msu.edu/sha...

Ants win a waxy race

...cond specialist ant (Camponotus schmitzi) lives in symbiosis with a pitcher plant which forms a slippery home coming when it rains. The plant used its slippery charateristic to catch insects, which slip and fall into the pitcher containing a digestive fluid in which they get trapped and die. The ant adjusts i...

Fungus-farming termites descend from an African rain forest Eve

...he marrying of termites and fungi in a mutualistic symbiosis has thus allowed both partners to conquer the savannah: agricultural termites and their mutualistic fungi are both more successful in this habitat than each of their non-agricultural sister groups, which thrive in the rain forest. Interestingly, tho...

Evidence of 600-million-year old fungi-algae symbiosis discovered in marine fossils

Stealth Worms May Improve Insect Pest Control

...not in and of themselves, but because they live in symbiosis with bacteria," Stock concludes. "Both the bacteria and the nematode need each other to survive, making them not only good as biological agents, but also as model systems for understanding basic questions in biology." Given the number of nematodes th...

Symbiotic bacteria protect hunting wasps from fungal infestation

...wolf Philanthus triangulum has evolved a defensive symbiosis with a new species of bacteria of the genus Streptomyces. Interestingly, this genus comprises the most important group of bacteria for the production of antibiotics for human medicine. Female beewolves provision their larvae with paralyzed honeybees...
