Recreational fish-catch data can help save money in monitoring invasive largemouth bass

Largemouth bass are native to North America, but they have been distributed worldwide for recreational fishing. When they’re in waters outside North America, largemouth bass can cause declines in native fish abundance, disrupting the ecosystem. Officials could save $1 million a year in monitoring for invasive fish, experts say, by using tournament fish-catch data.

Nation’s weather radar network used to track bird migration at night

The students have discovered a way to use the latest dual-polarization radar upgrade to measure broad-scale flight orientation of nocturnal migrant birds -- a promising development for biologists and bird enthusiasts.
