For the first time, state and federal wildlife biologists have come together to map the migrations of ungulates—hooved mammals such as mule deer, elk, pronghorn, moose and bison—across America’s West. The maps will help land managers and conservationists pinpoint actions necessary to keep migration routes open and functional to sustain healthy big-game populations.

“This new detailed assessment of migration routes, timing and interaction of individual animals and herds has given us an insightful view of the critical factors necessary for protecting wildlife and our citizens,” said USGS Director Jim Reilly.

The new study, Ungulate Migrations of the Western United States: Volume 1, includes maps of more than 40 big-game migration routes in Arizona, Idaho, Nevada, Utah and Wyoming.

“I’m really proud of the team that worked across multiple agencies to transform millions of GPS locations into standardized migration maps,” said Matt Kauffman, lead author of the

Maps: How employment in education has changed in each US state

  • The coronavirus pandemic has caused turmoil for education workers.
  • In addition to teachers, school staff, such as bus drivers, faced layoffs and furloughs amid closures.
  • A new analysis by The Pew Charitable Trusts looked at figures from the Bureau of Labor Statistics to determine how employment in education has changed from a year ago across the US.
  • Most states saw a decline between September 2019 and September 2020, but two states saw gains in local education employment and five saw gains in state education employment.
  • Overall in the US, September employment in state education is 10.6% lower than last year, and local education is down 6.9%.

CABI scientists have mapped the potential global spread of the devastating papaya mealybug (Paracoccus marginatus), highlighting new areas in Africa, Asia and the Americas into which this pest could potentially invade.

The papaya mealybug, which is native to Mexico and Central America, can have severe impacts upon livelihoods and food security. In Ghana, for example, infestations led to a 65% yield loss which reduced export earnings and resulted in the loss of 1,700 jobs.

Using location data received through collaborations with Kerala Agricultural University, India; the National Rice Research Institute, India; the Bangladesh Agricultural University; University of Queensland, Australia; the International Institute of Tropical Agriculture (IITA); Fujan Agriculture and Forestry University in China and CSIRO, researchers were able to model the potential distribution of this pest, taking into account environmental conditions, and the distribution of suitable host crops and irrigation patterns.

The researchers, led by CABI’s

The night sky is more than just the moon and stars, if you know when and where to look.

A clear night sky offers an ever-changing display of fascinating objects to see — stars, constellations, and bright planets, often the moon, and sometimes special events like meteor showers. Observing the night sky can be done with no special equipment, although a sky map can be very useful. Binoculars or a good beginner telescope will enhance some experiences and bring some otherwise invisible objects into view. You can also use astronomy apps and software to make your observing easier, and use our Satellite Tracker page powered by to find out when to see the International Space Station and other satellites. Below, find out what’s up in the night sky tonight (Planets Visible Now, Moon Phases, Observing Highlights This Month) plus other resources (Skywatching Terms, Night Sky
