Vast swaths of Pennsylvania forests were clear-cut circa 1900 and regrowth has largely been from local native plant communities, but a team of researchers in Penn State's College of Agricultural Sciences has found that invasive, non-native plants are making significant inroads with unconventional natural gas development.
Postdoctoral research fellow Julia Buck discovers a new paradigm for describing trophic cascades caused by infectious agents.
Whales, sharks, butterflies and lotus leaves might together hold the secret to saving the shipping industry millions and help save the planet, according to a marine biologist at the University of Portsmouth, UK.
A Northern Illinois University study finds that tallgrass prairie restoration at a large Illinois preserve is working at a foundational level -- in the soil. Bacteria in the soil are recolonizing and recovering on their own to resemble soil found in remnant prairies. The study shows that a carefully managed restoration can produce successes even beyond plant and animal biodiversity.
More than three quarters of plants and animals in England are likely to be significantly affected by climate change by the end of the century, say researchers.
Wild bees are important pollinators of many crop plants -- sometimes they are even more efficient than honeybees. Their numbers can be increased sustainably using simple means as a recent study has found.
A new theoretical study examines for the first time the limits of geckos' gripping ability in natural contexts.
A new global analysis of forest habitat loss and wildlife extinction risk published July 19 in the journal Nature shows that species most at risk live in areas just beginning to see the impacts of human activities such as hunting, mining, logging and ranching.
A plant parasitic nematode is a pest that parasitizes the roots of agricultural crops and creates nests called 'galls' which deprive plants of nutrition. Research from Japan on plant reactions to parasitic worms shows that parasitism activates plant stem cells which grow to form galls on their roots. This finding is expected to improve crop breeds and alleviate nematode damage, which is estimated to cost hundreds of billions of dollars each year worldwide.
Chemical compounds called cannabinoids are found in marijuana and also are produced naturally in the body from omega-3 fatty acids. A well-known cannabinoid in marijuana, tetrahydrocannabinol, is responsible for some of its euphoric effects, but it also has anti-inflammatory benefits. A new study in animal tissue reveals the cascade of chemical reactions that convert omega-3 fatty acids into cannabinoids that have anti-inflammatory benefits - but without the psychotropic high.
