While climate change is just one of the many factors influencing North American birds, its effects are significant and can interact with other stressors, such as habitat loss. A team of University of California, Davis, researchers found that the effects of extreme temperatures on avian reproduction can vary depending on the type of environment that birds call home. https://phys.org/news/2023-10-bird-reproduction-agricultural.html Ecology Agriculture Thu, 19 Oct 2023 14:00:01 EDT news616926619 High-latitude wilderness may be threatened by agriculture as the climate warms Humanity must cut carbon emissions and use farmland more efficiently to protect our planet's remaining wilderness, new research shows. https://phys.org/news/2023-10-high-latitude-wilderness-threatened-agriculture-climate.html Ecology Agriculture Thu, 19 Oct 2023 11:00:01 EDT news616924554 Do adult periodical cicadas actually feed on anything? Every so often, cicadas emerge above ground and blanket the Earth with their exoskeletons while emitting a high-pitched chirp from sunrise to sunset. The periodical cicadas in the genus Magicicada come every 13 or 17 years, though other types of cicadas emerge much more frequently in our neighborhoods. https://phys.org/news/2023-10-adult-periodical-cicadas.html Ecology Agriculture Wed, 18 Oct 2023 10:00:06 EDT news616842005 Sustainable smart agriculture with a biodegradable soil moisture sensor Increasingly limited land and water resources have inspired the development of precision agriculture, which is the use of remote sensing technology to monitor air and soil environmental data in real time to help optimize crop output.

As a bioparticle, it can act as a drug carrier, delivering medication directly to the gastrointestinal tract of fish in order to circumvent resistance to conventional antibiotics, for example. In addition, it is administered orally in powder form and is highly palatable to fish, increasing the probability of effective treatment while at the same time reducing the waste and pollution inherent in the medication of these animals. https://phys.org/news/2023-10-biomaterial-medication-fish-gut.html Biotechnology Agriculture Wed, 11 Oct 2023 12:53:03 EDT news616247581 Warm summers and wet winters yield better wine vintages, research shows Wine quality is notorious for varying from year to year, but what makes for a "good year"? In a paper publishing October 11 in the journal iScience, researchers show that weather plays an important role in determining wine quality. By analyzing 50 years' worth of wine critic scores from the Bordeaux wine region in relation to that year's weather, the researchers showed that higher quality wine is made in years with warmer temperatures, higher winter rainfall, and earlier, shorter growing seasons—conditions that climate change is predicted to make more frequent. https://phys.org/news/2023-10-summers-winters-yield-wine-vintages.html Agriculture Wed, 11 Oct 2023 11:00:01 EDT news616236722 Gene-edited chickens in the fight against bird flu Scientists have used gene editing techniques to identify and change parts of chicken DNA that could limit the spread of the bird flu virus in the animals. https://phys.org/news/2023-10-gene-edited-chickens-bird-flu.html Biotechnology Agriculture Tue, 10 Oct 2023 12:46:04 EDT news616160761 New research finds that reducing antibiotic usage in animal feed is not enough to combat antibiotic resistance A new study led by the University of Oxford has found that natural evolution of antibiotic resistance genes has maintained resistance in bacteria despite a reduction in the use of antibiotics.
