Georg Wilhelm Steller

As of tomorrow, a man named Georg Wilhelm Steller passed away 266 years ago.  Steller, as we talked about a few weeks ago, discovered a few very interesting animals, and was the first non-native (at least that we know of) to set foot in Alaska, in 1741.  He was therefore the first European naturalist to discover, as well as describe, a number of animals in the area.

Many of the members of the crew of the boat that he was on were coming down with scurvy, and Steller attempted to cull the growing epidemic by feeding berries and leaves to the crew.  No one really heeded his advice, which was why, on the returning journey, they all became shipwrecked, as only 12 crew members were actually able to physically move.  During the voyage almost half of the crew had died due to scurvy, and many, including the captain, died following the shipwreck.  With very little food and water, the survivors created a camp, suffering frequent raids by the arctic fox, which only served to increase their peril.

Nevertheless, Steller, apparently the stoic type, continued to learn more about the natural world of Alaska.  He recorded a good deal of information in regards to the Steller's sea cow (a relative of the manatee), which, as a species, only survived about 25 years after Steller first discovered them.  Other animals that he discovered, described, or both include the Steller's eider (a type of duck), the spectacled cormorant (like the sea cow, now extinct), the sea otter, Steller's sea lion, and the northern fur seal.

In 1742, the survivors were eventually able to build a new boat from the salvage, and returned to Avacha Bay in Russia.  Steller continued to explore the Kamchatka Peninsula in Russia for the next two years, but died in 1746 in transit to St. Petersburg.

One final thing that I find interesting about Steller has to do with the post-mortem publication of his journals.  They were published by the German zoologist and biologist Peter Simon Pallas who, you guessed it, is the namesake of the Pallas cat, or Pallas's cat, who was the first person to describe the animal in 1776.  These journals proved to be useful to other explorers of the same region such as Captain Cook.
An excellent picture that I took of the Pallas cat (if I do say so myself) from the Cheyenne Mountain Zoo

The Fauna of South Carolina: Cetaceans, Foxes and Otters

Here is the second in the "Fauna of South Carolina series."  Today, we are going to take a brief look at some of the cetaceans, foxes and otters that we saw while we were down there, either in the wild or in zoos.  Let's start with the otters.
River Otters ("Least Concern" by the IUCN) at Brookgreen Gardens
We saw both the otters and the foxes at Brookgreen Gardens, at their Lowcountry Zoo.  Not quite as cool as the foxes in my opinion were the river otters.  They were definitely really cool, as they were running around and playing a great deal, and we had a great view of them.  I'm not sure if I have ever seen otters playing so much, and seen it so well.  It was definitely quite a treat!  The range of the river otter is slightly weird; encompassing Oregon, Washington, and parts of California,and then extending throughout most of Alaska and Canada, and then coming down along the east coast of the United States, down to Florida, Mississippi, Alabama and Louisiana.

Prior to that, we had visited the fox exhibit.  We were looking for red fox and gray fox.  If I recall correctly (which I often don't), we were having trouble seeing the gray foxes, when I noticed something moving in one of the trees.  It was the gray fox!  I had no idea that foxes climb trees!  In fact, other than the raccoon dog found in Asia, I believe not many other canids in fact do climb.

 The gray fox, like the river otter, is labeled "Least Concern" by the IUCN.  Its range stretches from most of North America, down through Mexico, Central America, and into bits of South America.  The Channel Island Fox (a very interesting animal that we will by all means talk about at some point soon) is almost certainly descended from gray fox on the mainland. 


Instead of doing the cetaceans like we previously planned today, I think we should do them some other time.  See you later!
