From gametogenesis to spawning: How climate-driven warming affects teleost reproductive biology.

abstract：:In some small, often unstable, streams of the Gila River drainage, New Mexico, Gila trout Oncorhynchus gilae populations fluctuated numerically seasonally and annually. Few differences were noted in length-weight and size-structure comparisons, but Fulton condition index varied significantly. Time of sample and time s...
