“…The lower respiration rate in N. stygius compared to G. fossarum is in accordance with published reports that hypogean animals have lower metabolic activity than epigean ones (Hervant et al 1997;Hervant et al 1998;Spicer 1998;Hervant and Renault 2002;Simčič et al 2005). Lower metabolic activity is one of the most important adaptations in subterranean environments to low and discontinuous food supplies and to alternately hypoxic and normoxic waters.…”

“…Therefore, hypogean species have evolved a number of adaptations, which allow them to successfully exploit the subterranean environment. The ability to sustain a low metabolic activity is one of the most important adaptations of cave animals to low and discontinuous food supplies (Hervant et al 1997(Hervant et al , 1999(Hervant et al , 2001Spicer 1998;Hervant and Renault 2002) and to alternately hypoxic and normoxic waters (Hervant et al 1995(Hervant et al , 1996(Hervant et al , 1998Mejía-Ortiz and López-Mejía 2005).…”

Effect of fasting on hypogean (Niphargus stygius) and epigean (Gammarus fossarum) amphipods: a laboratory study

et al. 2009

Two amphipods, the hypogean Niphargus stygius and epigean Gammarus fossarum, were analyzed for fatty acid (FA) composition, electron transport system (ETS) activity and respiration (R) during a laboratory fasting experiment. In agreement with ETS and R measurements (and the ETS/R ratio), the hypogean N. stygius utilized FA more slowly than the epigean G. fossarum. Inter-specific differences in the utilization of certain FA during fasting were also revealed. While N. stygius tended to preserve all of its FA during the experimental fasting period, G. fossarum showed a tendency to utilize MUFA (monounsaturated FA) and SAFA (saturated FA) and preferentially retain PUFA (polyunsaturated FA). The significant correlations between ETS activity and composition of specific FA during fasting can be linked to R. During the fasting, both ETS activity and respiration rate of G. fossarum decreased, however, ETS/R ratio increased. In contrast, N. stygius did not show significant changes in these parameters. This is the first report, which connects ETS activity with changes in concentrations of specific FA during fasting. Such evolutionary adaptations of hypogean species enables them to better survive chronically low and/or discontinuous food supplies compared to epigean species, which live in environments where food shortages are much less frequent.

“…In addition to depigmentation and reduction (or loss) of eye structures, hypogean species possess characteristics that allow them to exploit successfully the subterranean environment. These generally include elongation of the body and (or) appendages, the development of extraoptic sensory structures, and a metabolic rate lower than that of closely related epigean species (reviews in Hüppop 1985;Hervant et al 1998).…”

Comparisons of circadian rhythmicity, behavior, and metabolism between surface-and cave-dwelling salamanders allow evolutionary trends in these processes to be elucidated. The proteid Proteus anguinus, an obligate cavedweller, showed no apparent daily rhythm of activity or resting metabolic rate. In contrast, the salamandrid Euproctus asper, a surface-dweller / facultative cave-dweller, had a circadian resting metabolic rate and activity cycle. These circadian rhythms had an endogenous component. The lives of both studied salamanders were characterized by long periods of inactivity punctuated by bouts of foraging or exploratory/predatory behavior. Proteus anguinus had reduced resting metabolic and spontaneous activity rates (considerably lower than those of most surface-dwelling amphibians), and therefore appears to be a good example of a vertebrate as a low-energy system. The low metabolic and activity rates of P. anguinus are interpreted as adaptations to a subterranean environment, where a poor and discontinuous food supply and (or) intermittent hypoxia may be present for long periods.Résumé : L'analyse comparée des rythmes circadiens, du comportement et de la consommation d'oxygène chez des amphibiens cavernicoles et épigés permet d'élucider certains des problèmes évolutifs liés à ces mécanismes. Le proteidé cavernicole Proteus anguinus ne possède pas de rythme journalier d'activité locomotrice ou de métabolisme de repos. Au contraire, ces deux variables comportent une importante composante circadienne (d'origine endogène) chez le salamandridé épigé / cavernicole facultatif Euproctus asper. Les deux urodèles étudiés ont de longues phases d'inactivité ponctuées de courtes périodes d'exploration du territoire liées à un comportement de prédation. Proteus anguinus possède un métabolisme de repos et une activité spontanée réduits par rapport à la majorité des amphibiens épigés et constitue donc un excellent exemple de vertébré envisagé comme un système à faible énergie. Ces faibles valeurs de métabolisme et d'activité sont interprétées comme étant des adaptations au milieu souterrain où les organismes subissent parfois des phases de jeûne et (ou) d'hypoxie longues et sévères. 1432Hervant et al.

“…Among these characteristics, and especially pertinent in this context, are the low metabolic rates in hypogean species (rates from 29-59%: Hervant et al 1998b) compared with surface members of their broad lineage, and reductions up to an order of magnitude in anchialine animals (Bishop et al 2004) that typically inhabit severely hypoxic water (Sket 1996;Humphreys 1999). Even in fish, cave-adapted forms had reduced standard (18-27%) and resting (19-53%) metabolic rates compared with epigean forms (Poulson 1985;Hüppop 1986).…”

“…The responses of crustaceans to PO 2 are complex and may have significant impact on energy balance in low-energy environments. The critical PO 2 level below which respiration rates could not be maintained, and post-hypoxic oxygen debt repayment, was lower in hypogean than in surface species (Hervant et al 1998b). Some hypogean species, having no critical PO 2 (Caine 1978;Danielopol et al 1994), are even considered to be oxyregulators (Hüppop 2000).…”
