ABSTRACT In order to estimate metabolic demands of desert pupfish for conservation purposes, we measured oxygen consumption in fish acclimated to the ecologically relevant temperatures of 28 or 33°C. For these experiments, we used fish derived from a refuge population of Devils Hole pupfish (Cyprinodon diabolis). Measurement of routine oxygen consumption (V̇O2,routine) revealed some 33°C-acclimated fish (10% of 295 assayed fish) periodically exhibited periods of no measurable oxygen consumption…

Oxygen consumption of desert pupfish at ecologically relevant temperatures suggests a significant role for anaerobic metabolism
TLDR
Evaluated data from pupfish exhibiting stable oxygen consumption indicates a substantial contribution of anaerobic metabolism to energy utilization by these fish and suggests that this observed ‘efficiency’ may result from significant anaer aerobic metabolism use.
Oxygen Consumption is Limited at an Ecologically Relevant Rearing Temperature in Pupfish Eggs.
TLDR
Oxygen consumption increased dramatically upon hatch, indicating that low oxygen conditions such as those present in Devils Hole may limit developing eggs.
Differential survivorship of congeneric ornamental fishes under forecasted climate changes are related to anaerobic potential
TLDR
Results clearly show that P. simulans has a larger scope for survival to higher energy demands due to its increased anaerobic potential compared to P. axelrodi, indicating that survival responses might be related to differences in relative gene expression of lactate dehydrogenase.
Ethanol metabolism varies with hypoxia tolerance in ten cyprinid species
TLDR
The findings that liver ADH activities were inversely related to hypoxia tolerance suggests that in all but Carassius spp.
Care and propagation of captive pupfish from the genus Cyprinodon: insight into conservation
TLDR
It is suggested efforts at restoring cover in Devils Hole will have the greatest impact on enhancing survivorship of this species especially in light of the reduced breeding opportunities that will likely result from continuing global climate change.
Reduced Oxygen as an Environmental Pressure in the Evolution of the Blind Mexican Cavefish
TLDR
The potential role of limited oxygen as a critical environmental feature of caves in the Sierra de El Abra is reviewed and evidence that Astyanax cavefish may have evolved adaptive features enabling them to thrive in lower oxygen compared to their surface-dwelling counterparts is reviewed.
The gut microbiome and its potential role in paradoxical anaerobism in pupfishes of the Mojave Desert
TLDR
It is speculated that Cetobacterium, a primary fermenter, also consumes ethanol through secondary fermentation via an alcohol dehydrogenase and therefore regulates the transition from paradoxical anaerobism to aerobic respiration in fish.
The gut microbiome and its potential role in paradoxical anaerobism in pupfishes of the Mojave Desert
TLDR
It is speculated that Cetobacterium, a primary fermenter, also consumes ethanol through secondary fermentation via an alcohol dehydrogenase and therefore regulates the transition from paradoxical anaerobism to aerobic respiration in fish.
Warming waters beget smaller fish: evidence for reduced size and altered morphology in a desert fish following anthropogenic temperature change
TLDR
Evidence is provided that the ecological changes associated with warming may not only lead to shrinking body size but also trigger shifts in morphology, and how human-induced environmental warming may also trigger morphological changes with potential relevance for fitness.

Physiological responses of postprandial red rock crabs (Cancer productus) during emersion
TLDR
Higher ammonia levels in postprandial crabs showed that cellular activities were still proceeding anaerobically, suggesting that although crabs can delay mechanical digestion during emersion, once intracellular digestion occurs they may be committed to these processes.
Spatial and Temporal Variation of Dissolved Oxygen and Ecosystem Energetics in Devils Hole, Nevada
TLDR
Because microbial biofilms are important components of this unique ecosystem, shifts in their composition or activity may threaten ecosystem stability by reducing background O2 concentrations below the physiological limits of the endangered Devils Hole pupfish and the entire biotic community.

TLDR
Examination of food availability and temperature in Devils Hole pupfish and Amargosa River pupfish suggests changes in environmental factors affecting the growth and thyroid hormone status of juvenile pupfish may play a developmental role in generating the morphological differences between C. diabolis in Devil's Hole and the refuges.

Abstract We tested the hypothesis that allochthonous carbon is important in the diet of the endemic pupfish Cyprinodon diabolis over a 3-year period in Devils Hole, Nevada. Devils Hole is a cavernous…

Ethanol Suppresses Ureagenesis in Rat Hepatocytes
TLDR
Acetaldehyde, derived from ethanol oxidation, suppresses ureagenesis by inhibiting exchange of mitochondrial substrates across the outer membrane by closing mitochondrial voltage-dependent anions channels (VDAC) and decreases outer membrane permeability.

TLDR
Little is known of the control of breathing during exercise, the switch from rhythmic to ram ventilation at high water velocities may be initiated by mechanoreceptors on the gill surface.
