Table 1 in Populations of Odontesthes (Teleostei: Atheriniformes) in the Andean region of Southern South America: body shape and hybrid individuals

Table 1. Sampling localities, basins, latitude, longitude, mean summer air temperature 1961-1990 (Temp, data from Servicio Meteorológico Nacional, Argentina, www.smn.gov.ar), species identification, and SL of Odontesthes specimens used in this study. All river drainages flow to the Atlantic, unless otherwise noted (Pacific). OB: O. bonariensis, OH: O. hatcheri, Hy: presumptive hybrids, showing key characters of both species; CA: Cluster Analysis; GMA: Geometric Morphometrics Analysis; N: number of specimens. In bold, differences between key, genetic, and morphological criteria. Presumptive hybrids were highlighted as * in Fig. 3 and bold characters in Table 2.
