The rate of extinction(灭绝)is eight times faster than that of mammals, birds and reptiles. “It should be of huge concern to all of us, for insects are at the heart of every food web—they pollinate(授粉) the large majority of plant species, keep the soil healthy, recyc...
that development of opposition to flumorph in P. sojae might be a two-step procedure, where high resistance phenotypes could develop slowly from low resistance ones. Further examination into molecular procedure highly verified that evolution of isolates highly resistant to flumorph occurs in a ...
Assembling a database that included every species of mammal was no easy task. It took the research team, headquartered at Aarhus University, months just to stitch together existing datasets and fill in missing holes in the data. They then pored over old maps and checked museum records to see ...
It was flowering away in splendid isolation, with not a single fly to pollinate it. There were a few winter gnats around, but as far as I know they don’t act as pollinators. This is a high risk strategy, but as the winters get milder, who knows whether early-flowering plants might...
