Dr. James A. Entry
He used to be known as a Soil Scientist (Environmental Microbiologist),
now we call him "Junior Ranger Jim" (see the hat he's wearing).

Junior Ranger Jim is wrestling aligators and pythons in the Everglades, surfing mighty waves on the ocean during hurricanes, and diving to new depths amid man-eating sharks. We will miss Jim's warm personality and quick wit. We all wish Jim the best of luck at his new home on the big, green, stinky swamp with huge swarms of blood sucking mosquitos!
