Researchers from three universities have measured more than 19,000 tropical moths from 1,100 species to find out whether their size varies with elevation. Scientists from Friedrich-Schiller-University Jena (Germany) worked on the study together with colleagues from Marburg in Germany and Connecticut in the USA. “Body size plays a central role in the ecology and evolution of organisms,” explains Dr. Gunnar Brehm of the University of Jena. The zoologist is the lead author of the study, which has just been published online.
