Vulnerability of pejerrey Odontesthes bonariensis populations to climate change in pampean lakes of Argentina

Journal of Fish Biology, 2010
The vulnerability of the pejerrey Odontesthes bonariensis population in Lake Chasicó was assessed under different climate change conditions. During the sampling period, the water temperature was adequate for fish reproduction and to sustain an adequate sex ratio. Climate‐driven higher temperatures, however, may severely distort population structure and
