... it responds to high temperature. However, the magnitude of this plasticity and the mechanisms underlying socially modulated thermal responses are unknown. Using the amphibious hermaphroditic mangrove rivulus fish Kryptolebias marmoratus as a model, we tested three hypotheses: (1) social stimulation affects...

... the alterations in skin structure and function that unfold during this transition from immersion to emersion. To test these hypotheses, we used the amphibious mangrove rivulus [ Kryptolebias marmoratus (Poey 1880)], which is a particularly opportune model system for studying the physiological and genomic...

...-licence-1-1/ Summary: Intrinsically low metabolic rates increase survival and fitness of an amphibious fish when access to water is limited; there is no apparent cost when water is abundant. Metabolism Life history Trade-off Kryptolebias marmoratus Mangrove rivulus Life...

... into a tight C shape, followed by straightening as the fish launches off of the caudal peduncle into ballistic flight. We asked whether similar motor control is used for both behaviors in the amphibious mangrove rivulus, Kryptolebias marmoratus . Fine-wire bipolar electrodes were percutaneously inserted...

... environments relative to air using the self-fertilizing amphibious mangrove rivulus, Kryptolebias marmoratus , which typically inhabits hypoxic, water-filled crab burrows. We found that adult mangrove rivulus released twice as many embryos in terrestrial versus aquatic environments and that air-reared embryos...

... Mangrove rivulus The transition from aquatic to terrestrial life represents a major step in vertebrate evolution because the physical conditions between these environments are dramatically different. Oxygen solubility is relatively low in water and even well-oxygenated aquatic environments contain...

...Alexander J. Pronko; Benjamin M. Perlman; Miriam A. Ashley-Ross SUMMARY Mangrove rivulus ( Kryptolebias marmoratus ) are small fusiform teleosts (Cyprinodontiformes) with the ability to locomote on land, despite lacking apparent morphological adaptations for terrestrial movement. Rivulus will leave...

... breathing is thought to minimize the energetic cost of respiration while maintaining oxygen uptake ( Milsom, 1991 ). Perhaps mangrove rivulus are able to accomplish such low ventilatory frequencies under normoxia because of the presence of dense epidermal capillary beds, which allow them to respire...
