J Exp Biol (2023) 226 (20): jeb246376.
Published: 31 October 2023
...Jamie K. Cochran; Catelyn Banks; David B. Buchwalter ABSTRACT All freshwater organisms are challenged to control their internal balance of water and ions in strongly hypotonic environments. We compared the influence of external salinity on the oxygen consumption rates ( Ṁ O 2 ) of three species...

... function across salinities, cardiac function after chasing to exhaustion was impaired, presumably as a consequence of atrioventricular block. Ligation reduced maximum O 2 consumption rate by 33% and 17% in fish acclimated to sea water and fresh water, respectively, which caused corresponding 41% and 17...

... in a dynamic environment may trade off with the capacity to deal with other stressors. This paper will explore studies on select fishes and invertebrates exposed to fluctuations in dissolved oxygen, salinity and pH. We assess the physiological mechanisms these species employ to achieve homeostasis...

.... trossulus varies on a seasonal basis, along an intertidal shore-level gradient, and with changing salinity. Acclimation to increased salinity (30 ppt compared with 15 ppt) increased freeze tolerance, and mussels were significantly more freeze tolerant during the winter. Mussel freeze tolerance also...

..., indicating stimulation of the HPI axis originates in the brain ( Craig et al., 2005 ). ACTH release by the pituitary appears to be insensitive to changes in plasma osmolality in Mozambique tilapia ( Seale et al., 2002 ), lending further support to the importance of CRF signaling during salinity stress...

.... Despite the potential benefits of increased mixing and transport of imbibed water for increasing the efficiency of absorptive processes, the effect of water salinity on intestinal motility in teleosts remains unexplored. By qualitatively and quantitatively describing in vivo intestinal motility...

...Casey A. Mueller; Eric Willis; Warren W. Burggren ABSTRACT A 3D conceptual framework of ‘critical windows’ was used to examine whether the morphometry of Artemia franciscana is altered by salinity exposure during certain key periods of development. Artemia franciscana were hatched at 20 ppt...

... , as a case study. Consistent with the extreme environmental variation that they experience in their salt marsh habitats, killifish have substantial capacity for both short-term resistance and long-term plasticity in the face of changing temperature, salinity and oxygenation. There is inter-population...

... control levels over time. Gill H + -ATPase activity increased by more than 45% 14 days after exposure to freshwater, whereas H + -ATPase mRNA levels were not affected by the salinity change. Within 4 days of freshwater exposure, gill Na + /K + -ATPase activity increased ∼43% over control levels, remaining...

... transparent and more conspicuous to predators. We tested this in the transparent grass shrimp, Palaemonetes pugio , which is found in shallow estuaries where both salinity and temperature change rapidly because of tidal cycles, evaporation and runoff. Animals originally kept at a salinity of 15 p.p.t...
