Coral reefs are retreating from equatorial waters and establishing new reefs in more temperate regions, according to new research in the journal Marine Ecology Progress Series. The researchers found that the number of young corals on tropical reefs has declined by 85 percent - and doubled on subtropical reefs - during the last four decades.
Canada has been battling a very active and destructive fire season on multiple fronts this year. A warming climate, very dry environment, and more extreme weather including severe thunderstorms has led to massive wildfires throughout the country.
A boiling point of 5900 degrees Celsius and diamond-like hardness in combination with carbon: tungsten is the heaviest metal, yet has biological functions - especially in heat-loving microorganisms. A team led by Tetyana Milojevic at the University of Vienna report for the first time rare microbial-tungsten interactions at the nanometer range. Based on these findings, also the survivability of microorganisms in outer space conditions can be investigated. The results appeared in Frontiers in Microbiology.
In recent years, increasingly more observational and simulation evidence shows that the mid-high latitude climate variability has an important impact on the East Asian monsoon climate, and its impact is as significant as the tropical climate variability, which has been of more concern in previous studies. Among the evidence, Chinese scientists have produced systematic research results and played a crucial role in promoting the development of climate research in East Asia.
UC Riverside scientists have decoded the genome of black-eyed peas, offering hope for feeding Earth's expanding population, especially as the climate changes. Understanding the genes responsible for the peas' drought and heat tolerance eventually could help make other crops tougher too.
The El Niño-Southern Oscillation has been responsible for widespread, simultaneous crop failures in recent history, according to a new study. This finding runs counter to a central pillar of the global agriculture system, which assumes that crop failures in geographically distant breadbasket regions such as the United States, China and Argentina are unrelated. The results also underscore the potential opportunity to manage such climate risks, which can be predicted using seasonal climate forecasts.
A new computer model incorporates how microscopic pores on leaves may open in response to light -- an advance that could help scientists create virtual plants to predict how higher temperatures and rising levels of carbon dioxide will affect food crops.
The movie Finding Nemo could have a much darker sequel -- as artificial light in coral reefs leaves the famous fish unable to reproduce offspring, according to a new study. Results from a new study published in Biology Letters show an increasing amount of artificial light at night (ALAN) in coral reefs, even at relatively low levels, masks natural cues which trigger clownfish eggs to hatch after dusk.
Researchers have revealed that atmospheric waves originating from convection over the Indian Ocean had a dramatic impact on climate conditions over South America and South Atlantic, leading to drought and marine heatwaves. Importantly, these conditions are not a one-off and are likely to happen again.
Researchers equipped monarch butterflies and green darner dragonflies with radio transmitters and tracked them through southern Ontario and several northern States to learn how environmental factors affect daytime insect migration. Learning about what happens to insects during their migration may help in conservation efforts. The study found wind and temperature are more important influences than precipitation for bugs on autumn migration flights spanning thousands of kilometers between their breeding and wintering grounds.
