Global Warming Shifts Arctic Wildlife Movement Patterns

For animals in the Arctic, life is a balancing act. Seasonal cues, such as warmer spring temperatures or cooler temperatures in the fall, tell animals when to migrate, when to mate, and when and where to find food. Predators and prey, birds and mammals alike follow this natural schedule, and an overall shift of just a few days or weeks could have unknown impacts on these animals and ecosystems.

These changes in seasonal timing are already starting – although the shifts differ between species and populations – according to a new study published Nov. 5 in Science.

The timelapse shows the movement patterns for various animals (colors indicate different animal types) over the course of a year. Animal migration in the Arctic is highly seasonal, as various species and populations move around in search of food, suitable temperatures, and places to mate and raise their young.

Rhinos Return

Conservationists will repopulate Zimbabwe’s Gonarezhou National Park with black rhinos before the end of the year, bringing the critically endangered animals back 27 years after they went locally extinct.

The Gonarezhou Conservation Trust has hired 39 game rangers, mainly from areas around the park, and trained them to protect the returning rhinos. South Africa’s CAJ News reports the animals first went extinct in the area sometime in the 1930s or 1940s.

A similar reintroduction project between 1969 and 1977 saw rhino numbers increase to about 140 before a civil war in neighboring Mozambique caused the park to close. By 1994, the rhinos were extinct there again.
