Searching for Narwhals

narwhalThere is not a great deal known about the narwhal, a whale most familiar for its long spiraled horn. Researchers are trying to change that by attempting to net and tag a narwhal in Greenland.  Thousands of narwhals spend their summer in the cold waters off of Greenland’s shore.

Researcher Kristin Laidre has spent the last eight years attempting to tag a narwhal with a satellite transmitter which would send a variety of information. She is interested in knowing where narwhals travel and how deep they dive.

Laidre has managed to attach satellite transmitters to narwhals in other regions, but the Greenland population seems to be much more difficult to get close to.  Perhaps in another summer she’ll get lucky and finally attach a transmitter, but for her, this summer has ended the same way the last eight have.

Pikas May End Up on Endangered Species List

pikaClimate change may be to blame for decreasing populations of pikas, a furry relative of rabbits. Pikas make their home in the mountainous regions of the western United States but are threatened by rising temperatures. While other animals are able to move as a way to adapt to changing temperatures, pikas will not migrate. Once they decide on a home they will stay there, even if it results in their death.

If the pika becomes listed as a threatened or endangered species, laws can be changed or created to curb activities that create greenhouse gases.
