The analytical method provides new insight into the impact of agriculture on insect decline
In homogenous habitats such as fields, insect communities can be recorded more rapidly and completely than diverse, close-natural habitats. Credit: Sophia Hochrein/Universität Würzburg New research by Julius Masimilians and Werzburg shows that the impact on agricultural insect diversity is more severe than previously thought. It has long been known that agriculture contributes to lower insect biodiversity. Host plant loss, frequent…

“Preventive measures” are the logical method for deep sea mining, researchers say
A state that has expressed a specific position in international submarine authorities. Credit: rifs@gfz Pressure on the International Submarine Authority (ISA) has finalized and adopted regulations on deep sea mining. While some ISA members hope for immediate progress, more and more states are demanding more time to study the environmental impact of raw material mining on the seabed and develop…

Research is underestimated by the biocher carbon storage capacity by the evaluation method of outdated.
Credit: IQBAL FAROOZ of Pexels Bi Chart, a charcoal material derived from plant biomass, has long been welcomed as a promising tool for removing carbon dioxide. However, new research by researchers at Stanford University emphasizes serious problems. The current method for evaluating the potential of carbon storage of bi -charcoal may significantly underestimate its true environmental advantages. This paper, published…

Research team develops more comprehensive method to monitor lobster industry
Credit: CC0 Public Domain Maine’s lobster fishery supports thousands of jobs across the state and is extensively monitored. Management efforts are informed by biological monitoring surveys that observe changes in lobster abundance and distribution, as well as dealer and harvester reports from the industry. But these statistics do not tell the whole story of an industry reeling from supply, market…
