• Distribution and ecology. Echinodorus nenufar is currently known from temporary aquatic habitats in the western Chaco region of northern Argentina (Salta Province) and western Paraguay (Boquerón Department), at elevations of 250 – 270 m a. s. l. (Fig. 3). Between late November and early May, individuals were observed at a range of developmental stages across various habitats. These stages include submerged, floating, and emergent blades, as well as mature and juvenile terrestrial forms. Among these, floating and juvenile terrestrial forms were most frequently observed, whereas fully mature emergent individuals were relatively uncommon. The species appears to exhibit a life-history strategy analogous to that of seasonal killifishes (Cyprinodontiformes, Rivulidae) inhabiting the same ephemeral environments (Calviño et al. 2016; Alonso et al. 2018). Like these fishes, E. nenufar seems to rely on the simultaneous presence of multiple life stages and overlapping generations as an adaptation to the unpredictability of flooding and drought events beyond typical seasonal cycles.1 esp.
