Principal morphological traits significantly higher in the terrestrial morphotype (Tm) than in the aquatic morphotype (Am) are represented in bold, and in italic when Am is significantly higher than Tm. When the terrestrial condition (−t) values are greater than aquatic (−a), it is represented in bold, in italic when (−a) was significantly greater than (−t). Significance codes: 0 “***”; .001 “**”; .01 “*”; nonsignificant “NS.”
