Researchers from Tokyo Metropolitan University and Hosei University have discovered a new species of large, tropical centipede of genus Scolopendra in Okinawa and Taiwan. It is only the third amphibious centipede identified in the world, and is the largest in the region, 20 cm long and nearly 2 cm thick. It is also the first new centipede to be identified in Japan in 143 years, testament to the incredible biodiversity of the Ryukyu Archipelago.
A new publication offers a comprehensive guide to help plant scientists communicate their work to the world. An Iowa State University scientist who contributed to the multi-institutional effort says it's critical that plant scientists emphasize outreach to make sure plant science is able to meet the demands of climate change and population growth.
One of the most comprehensive statistical analyses of drivers of food insecurity across 65 countries has concluded that household income consistently explains more discrepancy in food security than any other factor, including agricultural land resources and production.
Collaborative research of the University of Jyväskylä and Natural Research Institute Finland presents new evidence of the effects of enriched rearing on well-being of aquaculture fishes. The research demonstrates that stone enrichments that have been previously conditioned in lake water significantly improve survival of fish compared to clean stones. Also a higher number of stones has a similar positive effect. The results have practical implications for prevention of aquaculture diseases. The study was published in Antibiotics in March 2021.
Research in the Peruvian Andes highlights critical climate threats to montane forests and urges for current conservation plans to take climate projections into account.
The first photosynthetic oxygen-producing organisms on Earth were cyanobacteria. Their evolution dramatically changed the Earth allowing oxygen to accumulate into the atmosphere for the first time and further allowing the evolution of oxygen-utilizing organisms including eukaryotes. Eukaryotes include animals, but also algae, a broad group of photosynthetic oxygen-producing organisms that now dominate photosynthesis in the modern oceans. When, however, did algae begin to occupy marine ecosystems and compete with cyanobacteria as important phototrophic organisms?
Researchers at The University of South Australia's Future Industries Institute have developed technology that could eliminate water stress for millions of people, including those living in many of the planet's most vulnerable and disadvantaged communities.
Agricultural producers deal firsthand with changing weather conditions, and extreme events such as drought or flooding can impact their productivity and profit. Climate change models project such events will occur more often in the future. But studies of the economic consequences of weather and climate on agriculture typically focus on local impacts only.
Australian pineapple, Danish trout, and Midwestern U.S. corn farmers are not often lumped together under the same agricultural umbrella. But they and many others who raise crops and animals face a common problem: excess nitrogen in drainage water. Whether it flows out to the Great Barrier Reef or the Gulf of Mexico, the nutrient contributes to harmful algal blooms that starve fish and other organisms of oxygen.
Researchers conducted the first large-scale survey of the microbiota present in the seamount's ferromanganese crusts, describing bacteria and archaea involved in the nutrient cycle and formation of metals. Brazil has mineral exploration rights to the Rise, but mining there will have a major environmental impact.
