Juvenile Atlantic and shortnose sturgeons (family: Acipenseridae) have different hematological responses to acute environmental hypoxia
(University of Chicago Press, 2005)Experiments were conducted to determine the behavioral and physiological responses to acute hypoxic challenges in Atlantic (Acipenser oxyrinchus) and shortnose (Acipenser brevirostrum) sturgeons. We measured the ventilatory ... -
Physiological and molecular mechanisms of osmoregulatory plasticity in killifish after seawater transfer
(The Company of Biologists, 2008-08)We have explored the molecular and physiological responses of the euryhaline killifish Fundulus heteroclitus to transfer from brackish water (10% seawater) to 100% seawater for 12 h, 3 days or 7 days. Plasma [Na+] and [Cl–] ... -
Intrinsic mechanical properties of the perfused armoured catfish heart with special reference to the effects of hypercapnic acidosis on maximum cardiac performance
(2009-05)The armoured catfish, Pterygoplichthys pardalis, is known to be extremely tolerant of environmental hypercarbia (elevated water CO2 tensions), which occurs in their natural environment. In addition, previous studies have ... -
Exceptional CO2 tolerance in white sturgeon (Acipenser transmontanus) is associated with protection of maximum cardiac performance during hypercapnia in situ
(University of Chicago Press, 2011)White sturgeon rank among the most CO2-tolerant fish species examined to date. We investigated whether this exceptional CO2 tolerance extended to the heart, an organ generally viewed as acidosis intolerant. Maximum cardiac ... -
Low-O2 acclimation shifts the hypoxia avoidance behaviour of snapper (Pagrus auratus) with only subtle changes in aerobic and anaerobic function
(The Company of Biologists, 2013-02)It was hypothesised that chronic hypoxia acclimation (preconditioning) would alter the behavioural low-O2 avoidance strategy of fish as a result of both aerobic and anaerobic physiological adaptations. Avoidance and ... -
Could thermal sensitivity of mitochondria determine species distribution in a changing climate?
(The Company of Biologists, 2014-07)For many aquatic species, the upper thermal limit (Tmax) and the heart failure temperature (THF) are only a few degrees away from the species' current environmental temperatures. While the mechanisms mediating temperature-induced ... -
Lab-on-a-chip technology for a non-invasive and real-time visualisation of metabolic activities in larval vertebrates
(SPIE, 2015-06-01)Non-invasive and real-time visualisation of metabolic activities in living small organisms such as zebrafish embryo and larvae has not yet been attempted due to profound analytical limitations of existing technologies. ... -
Hagfish: Champions of CO2 tolerance question the origins of vertebrate gill function
(Macmillan Publishers Ltd., 2015-06-09)The gill is widely accepted to have played a key role in the adaptive radiation of early vertebrates by supplanting the skin as the dominant site of gas exchange. However, in the most basal extant craniates, the hagfishes, ... -
Interaction of osmoregulatory and acid-base compensation in white sturgeon (Acipenser transmontanus) during exposure to aquatic hypercarbia and elevated salinity
(The Company of Biologists, 2015-09)Migratory fishes encounter a variety of environmental conditions, including changes in salinity, temperature and dissolved gases, and it is important to understand how these fishes are able to acclimate to multiple ... -
Preferential intracellular pH regulation: Hypotheses and perspectives
(The Company of Biologists, 2016-08)The regulation of vertebrate acid–base balance during acute episodes of elevated internal PCO2 is typically characterized by extracellular pH (pHe) regulation. Changes in pHe are associated with qualitatively similar ... -
[Pre-print] The effect of substrate rearing on the growth, aerobic scope, and physiology of larval white sturgeon (Acipenser transmontanus)
(John Wiley & Sons, Inc., 2018-04-24)The effect of substrate on growth and metabolic rate was assessed in larval white sturgeon (Aciperser transmontanus). Yolk sac larvae (YSL) were reared in bare tanks or tanks with gravel as substrate from hatch until ...
