Researchers counting and measuring stream fishes sampled as part of a multi-year study of the effects of streamflow variation on fish population dynamics. This work was a component of the USGS WaterSMART, Apalachicola-Chattahoochee-Flint focal area study. Shown right to left: Rachel Katz (Univ. of GA), Paula Marcinek (GA DNR), and Mary Freeman (USGS).

Box turtle with trail laying device designed by Dr. Lucille Stickel in the 1940s. To track turtle movements, Dr. Stickel improved on an earlier trailer design described in 1927 and noted, “Details of travels can be followed for weeks or months by attaching thread- laying devices to their carapaces.

A researcher measures the snout-vent length of a red eft (Notophthalmus viridescens). The snout-vent length is a measure of the length of a salamander from its snout to its cloaca (located just behind the hind legs).
