Population divergence in the wheat leaf rust fungus Puccinia triticina is correlated with wheat evolution.

abstract：:Flies from a wild type strain of Drosophila melanogaster, previously kept at 25 degrees C, were reared at either 20, 25 or 29 degrees C. As expected, developmental time and adult body size decreased with increasing temperature. Adult longevity of flies reared at 25 degrees C was slightly greater than that of flies rai...
