Metabolic rates of animals in different environments

Henning Schneider, Associate Professor, Biology Department

Henning Schneider’s class in Animal Physiology usually visits the Nature Park early during fall semester.  The students collect various organisms to test hypotheses about metabolic rates in different environments.  The students collect mostly insects and amphibians from dry and wet habitats throughout the park   Questions addressed include what species is it?  What types of adaptations do the organisms exhibit?  How do these adaptations help the organisms survive and reproduce in their given environment?  Students bring some insects back to the lab where they take measurements of respiration rates and compare CO2 output between organisms that occur in wet versus dry habitats.  This lab exercise is an effective way to illustrate concepts for this course, but it’s more effective during fall semester than spring semester because it’s usually too cold to find active organisms in January!
