Analyzing the full life cycle of long-term droughts and how they relate to El Niño and La Niña conditions in the Pacific Ocean could eventually lead to better prediction of damaging, multiyear droughts in the Southwestern US.
We now know the DNA of guacamole.
This study, published in Molecular Plant-Microbe Interactions, is the most complete study to date about the role of hormones in galls, measuring 15 plant hormones belonging to 5 different classes. These findings can be used as a model for pest management and could help the agriculture and forestry industries better understand what makes plants resistant to pests.
How much carbon dioxide can tropical rainforests absorb? Investigations by an international team of researchers with significant involvement from the Technical University of Munich (TUM) indicate that the absorption capacity is severely limited by the phosphorus content of the soil.
PLANTS It has long been known that some plants tolerate drought better than others. As some of the first to do so in the past 100 years, Danish scientists have investigated the mechanisms behind the Aloe plant's ability to survive extended periods of drought. New knowledge could contribute to more resilient crops for a future of more weather extremes.
A phenomenon that makes coral spawn more than once a year is improving the resilience of the Great Barrier Reef. The discovery was made by University of Queensland and CSIRO researchers investigating whether corals that split their spawning over multiple months are more successful at spreading their offspring across different reefs.
A study that looks at how temperature influences the development of painted turtles may lead biologists to rethink the theoretical frameworks they use when analyzing the topic. The study, led by an Iowa State scientist, found wide variation within local populations, suggesting temperature sensitivity of embryonic development can vary significantly from one turtle nest to another within a single population.
Staring at seagulls makes them less likely to steal your food, new research shows.
Say you're a scientist who studies the origins and history of food, and you want to communicate to the world your findings that the all-American hamburger -- including the side of fries -- doesn't contain a single ingredient that originally came from the United States. You could publish an article in a top-notch journal, ask a communications officer to write a press release about the paper, or take to Twitter and tell your hundreds of devoted followers.
Fire is a natural part of western forests, but the changing nature of fire in many parts of North America may pose challenges for birds. One bird in particular, the Black-backed Woodpecker, specializes in using recently-burned forests in western North America, but new research suggests that these birds actually prefer to nest near the edges of burned patches -- and these edges are getting harder to find as wildfires have become bigger and more severe.
