Arctic fox in Svalbard, Norway

In the Arctic there has been a change in the distribution of both red and arctic foxes. Red foxes have expanded their territory to the North as the climate has warmed, at the expense of arctic foxes.

Due to a lack of observations of interactions between the two fox species, biologists have been unsure whether the loss of arctic fox territory was due to direct competition, or if they were indirectly competing for the same food. Rodnikova et al have now reported observing a red fox intruding upon a arctic fox den in 2007.

A recent Reuters story reports that biologists in Guatemala rely on Calvin Klein's Obsession for Men to attract jaguars for tracking and research purposes.

Use of the cologne stems from research done by The Wildlife Conservation Society at the Bronx Zoo, where researchers tested the effect of numerous scents on cheetahs. According to a recent Wall Street Journal article, it was discovered that out of 24 scents tested, Obsession for Men was the favorite, with Nina Ricci's L'Air du Temps coming in second. Others fared much worse, such as Estée Lauder's Beautiful and Revlon's Charlie.
