Global determinants of insect mitochondrial genetic diversity

C. M. French, L. D. Bertola, A. C. Carnaval, E. P. Economo, J. M. Kass, D. J. Lohman, K. A. Marske, R. Meier, I. Overcast, A. J. Rominger, P. Staniczenko, M. J. Hickerson

The paper maps global insect mitochondrial genetic diversity, finding a quadratic latitudinal gradient and correlations with temperature and climate stability.

Complex genetic patterns and distribution limits mediated by native congeners of the worldwide invasive red-eared slider turtle

S. Espindola, E. Vazquez-Dominguez, M. Nakamura, L. Osorio-Olvera, E. Martinez-Meyer, E. A. Myers, I. Overcast, B. N. Reid, F. Burbrink

The paper studies genetic patterns and distribution limits of invasive red-eared slider turtles and their native congeners, finding genetic differentiation and reduced gene flow despite geographic contact.
