Found: First lungless frog
Researchers have confirmed the first case of complete lunglessness in a frog, according to a report in the April 8th issue of Current Biology, a publication of Cell Press. The aquatic frog Barbourula kalimantanensis apparently gets all the oxygen it needs through its skin. view more (2008-04-08)
Morphology of fossil salamanders reflects climate change
A fossil record of the Tiger Salamander (Ambystoma tigrinum) shows population-wide changes in body size and morphology in response to climate change over the last 3,000 years. view more (2005-09-13)
New markers of climate change
A new way to monitor the effects of climate change on rainforests is being investigated at Cambridge University. Researchers are using biomarkers in the shape of epiphytes ('air-plants' which grow on other plants) to find out how their photosynthesis and water evaporation have been affected by climate change over the last 50 years. view more (2005-07-13)
Models Simulate Nitrate Dynamics in Garonne, Southwest France
The over-enrichment of fresh, transitional, and marine waters with nitrogen (N) can lead to problems associated with eutrophication, such as a change in species composition of aquatic plants and nuisance algal blooms. In this context, dynamic models of flow and water quality are required to aid the implementation of the Water Framework Directive... view more... (2009-01-06)
Fish food fight: Fish don't eat trees after all, says new study
What constitutes fish food is a matter of debate. A high-profile study a few years ago suggested that fish get almost 50 percent of their carbon from trees and leaves, evidence for a very close link between the terrestrial and aquatic ecosystems. view more (2009-11-24)
Milk cures plant disease
Research at Harper Adams University College has shown how spraying wheat plants with milk can help to cure mildew disease. South American research showed four years ago that milk could help in the fight against mildew disease on squash plants, and milk is used to treat this disease by some organic gardeners, as well as by grape vine growers in... view more...

Insects see crops clearly when the weeds have gone
All gardeners know that their plants have to compete against insects and weeds. We apply insecticides to protect plants from the munching hordes, and we apply herbicides, or hoe, to protect plants from weeds. But, according to Stan Finch and Rosemary Collier of Horticulture Research International, Wellesbourne, the latter is a bad move that... view more... (2003-06-05)
Strange properties of the tequila plant studied by Mexican student
Tequila is the national drink of Mexico and is also hugely popular worldwide. Now a Mexican student has come to England to study the unusual properties of tequila plants. Postgraduate student Ivan Saldana Oyarzabal, from Guadalajara, which is 50km from the town of Tequila, is studying Agave tequilana and its unusual behaviour at the University of... view more...

How Increased UV Exposure Impacts Plants
As the first plant life to emerge from the water and develop on dry earth, bryophytes offer a unique opportunity for researchers to understand the development of protections against ultraviolet radiation. view more (2009-03-10)
Researcher discovers pathway plants use to fight back against pathogens
Plants are not only smart, but they also wage a good fight, according to a University of Missouri biochemist. Previous studies have shown that plants can sense attacks by pathogens and activate their defenses. view more (2008-04-01)
Sequence matters in droughts and floods
When extremes of drought and flood come in rapid succession, the extent of damage to vegetation may depend in part on the sequence of those events, according to a new study published in The American Naturalist. view more (2009-01-08)
New AQUIRE database on STN: Toxic Effects of Chemicals to Aquatic Organisms
Karlsruhe, October 2002 - FIZ Karlsruhe, European partner of STN International, one of the world's leading online providers of scientific and technical information, has announced the launch of the AQUIRE database. AQUIRE contains scientific papers published both nationally and internationally on the toxic effects of chemicals to aquatic organisms... view more... (2002-10-18)
Grazer diversity counteracts plant diversity effects on ecosystem functioning in seagrass beds
Several influential experiments have shown that high plant diversity enhances ecosystem productivity, animal diversity, and invasion resistance. Yet theory predicts that plant and herbivore diversity, which often co vary in nature, should have countervailing effects on ecosystem properties. In the July issue of Ecology Letters, Duffy, Canuel, and... view more... (2003-07-02)
Natural-born divers and the molecular traces of evolution
An aquatic lifestyle imposes serious demands for the organism, and this is true even for the tiniest molecules that form our body. view more (2009-06-29)
ON TRAILS OF ANCIENT SEA GRASSES
Paleobotanists from St. Petersburg have found that ancestry of sea grasses had come to sea from desert 40 million years ago. The study was supported by International Science Foundation, Smithsonian Institution, Washington D. C., and by Linnean Society of London. It is not easy to reconstruct how life developed on the Earth - too little stuff had... view more... (2000-12-01)
Getting plants to rid themselves of pesticide residues
Scientists in China are reporting the "intriguing" discovery that a natural plant hormone, applied to crops, can help plants eliminate residues of certain pesticides. view more (2009-09-10)
Spread of plant diseases by insects can be described by equations that model interplanetary gravity
Researchers from Penn State University and the University of Virginia show that the spread of diseases by insects can be described by equations similar to those that describe the force of gravity between planetary objects. view more (2006-09-05)
Plants, plasmids and possibilities — Methods permit functional gene studies in plants
Decaffeinated coffee plants, pest-resistant cotton, and Vitamin A-producing rice varieties have all been developed by introducing genes into plants. view more (2006-12-04)
Parasites might spur evolution of strange amphibian breeding habits
Parasites can decimate amphibian populations, but one University of Georgia researcher believes they might also play a role in spurring the evolution of new and sometimes bizarre breeding strategies. view more (2007-11-15)
Woody and aquatic plants pose greatest invasive threat to China
Although China currently has fewer invasive woody plants than the United States, China's potential for invasion by nonnative trees and shrubs is high, according to an article in the May 2008 issue of BioScience. view more (2008-05-01)
