Abstract: The troglobitic electric fish Eigenmannia vicentespelaea, endemic to a single cave-system and included in the Brazilian Red List of Threatened Fauna, was studied in relation to population densities and habitat. For comparison, we used the epigean species, E. trilineata. We verify if the population densities recorded for E. vicentespelaea follow the pattern observed for other subterranean fishes; if there are seasonal fluctuations in these densities and which environmental variables explain the densities variat… Show more

“…Moreover, it arose that warming temperature can cause heat stress to water organisms like fishes and are projected to undergo physiological impairment and behavioral changes relative to their growth, survival, and environmental disturbance [31]. Their limited environment will become harmful in a warming temperature scenario since their environment is so limited and they have no capacity for possible migrations in order to reproduce their species [32][33][34][35][36][37][38][39][40].…”
