Second Place - Nicholas Freymueller (IMAGE) American Institute of Biological Sciences Caption Nicholas Freymueller, a master's student at the University of New Mexico, won second place. In this photograph, Freymueller measures the lower carnassial length of the late Pleistocene-age scimitar cat (Homotherium serum) at the Texas Memorial Museum in Austin. Molar lengths allow paleoecologists to determine the body size of extinct species, which is crucial in understanding how they interacted with each other in ancient ecosystems.
