Performance across extreme environments: comparing waterfall climbing among amphidromous gobioid fishes from Caribbean and Pacific Islands
Amphidromous gobioid fishes have colonized streams on tropical and subtropical volcanic islands across the globe. Such streams are often characterized by steep gradients, high velocity currents, and even waterfalls as in-stream obstacles; however, the ability to climb waterfalls has evolved in many goby species, allowing juveniles returning from the ocean to penetrate upstream reaches. Past stu...
متن کاملOntogenetic change in novel functions: waterfall climbing in adult Hawaiian gobiid fishes
Juveniles from three species of Hawaiian gobiid fishes climb waterfalls as part of an amphidromous life cycle, allowing them to re-penetrate adult upstream habitats after being swept out to the ocean upon hatching. The importance of climbing for juvenile stream gobies is well established, but adult fishes in upstream island habitats also face potential downstream displacement by catastrophic di...
متن کاملKinematics of waterfall climbing in Hawaiian freshwater fishes (Gobiidae): vertical propulsion at the aquatic–terrestrial interface
To reach adult habitats, juveniles of three species of Hawaiian gobies (fishes under 3 cm long) climb waterfalls up to 350 m high, over 10 000 times their body length. The demands of moving through such an extreme environment could constrain the range of viable locomotor mechanisms that these fishes use. Previous qualitative observations indicated that Lentipes concolor and Awaous guamensis use...
متن کاملAnomalous pull-off forces between surfactant-free emulsion drops in different aqueous electrolytes.
A systematic study of collisions between surfactant-free organic drops in aqueous electrolyte solutions reveals the threshold at which continuum models provide a complete description of thin-film interactions. For collision velocities above ~1 μm/s, continuum models of hydrodynamics and surface forces provide a complete description of the interaction, despite the absence of surfactant. This inc...
متن کاملEpithelium: sticking it out, together.
SOME CELLS LIVE WITHIN A COMMUNITY of neighboring cells, restricted in time and space, most prominently interacting with cells of similar functions. Some cells live within fixed positions, surrounded on all sides by a loose forest of matrix proteins. Some cells live as nomads, wandering throughout the body, responding to needs as they arise. Each cell is part of an elaborate orchestra, coordina...
