On the other hand, none of the other enzyme systems searched for (i.e., ALPDH, STRDH, and ADH) were detected in any of the tissues used. Petrolisthes armatus (Gibbes, 1850) is a porcellanid crab with a wide geographical distribution. 1. Females are assumed to brood two or three times during their lifespan, producing 500 - 1000 eggs. In the experiments designed to test hypoxia tolerance, no differences were observed in the behavior of individuals between the control and the treatment during the first hour of exposure of P. laevigatus to low oxygen levels.

A similar situation is seen in the intertidal halfcrab Petrolisthes elongatus, a species whose postembryonic eye-growth patterns resemble those in L. exotica (Meyer-Rochow et al., 1990). doi: 10.1093/iob/obz024.

Octopuses were exposed to ambient temperatures over this period (ranging between 14 and 17.9C; mean: 16.10.07C) and fed ad libitum on live crabs (Petrolisthes elongatus). These results suggest that at approximately 16.5C P. laevigatus reaches its upper thermal limit for the maintenance of a respiration rate, which allows it to keep a homeostatic state within aerobiosis, in agreement with the general model proposed by Stebbing (1981). Water salinity was measured using an automatic salinometer.

The limited tolerance of P. laevigatus to experimental hypoxia (less than three hours) suggests the absence of the glucose-succinate pathway, because organisms generally use the lactate and opines pathways to maintain metabolic activity under hypoxic conditions and the glucose-succinate and aspartate-succinate pathways for long-term survival in hypoxic/anoxic environments (Livingstone, 1991). I am interested using fundamental ecology to improve our understanding of the response of marine communities to global change and to develop more robust conservation and . Depending on the enzyme under study, 3.2 mM pyruvate and 5.4 mM arginine, 3.2 mM pyruvate and 250 mM alanine, or 3.2 mM pyruvate and 250 mM glycine was added for OPDH, ALPDH, and STRH, respectively.

Gaseous nitrogen was bubbled through the water of the treatment jars for a whole night to reduce dissolved oxygen concentration before the experiment (Table 1). The reduction in the respiration rate observed at 18C and 20C can be interpreted either as the beginning of the organisms decompensation, or the starting point for another homeostatic mechanism independent of oxygen consumption. Low activity of OPDH was found in the muscle and heart, with no activity detected in gills and visceral mass (Fig. Diurnal and seasonal variation in physico-chemical conditions within intertidal rock pools.

Four other jars were filled with water treated similarly although, in addition, it had been boiled for 2 h and allowed to cool to 14C. In half of the articles gleaned, only the name of the animal under study was given; the other half mentioned "adult" or "mature" animals; twelve papers provided information on size or age of the experimental animal and six gave the sex. To examine juvenile growth prior to the manipulative experiment, a random sub-sample of animals were weighed at days 1 (hatching), 9, 20, 32, 84 and 156 . We report here measurements of specific aerobic respiration rates, activities of pyruvate oxidoreductases, and resistance to hypoxia of Petrolisthes laevigatus under laboratory conditions. | Abstract: I isolated and developed primers for 17 microsatellite loci in the anomuran crab Petrolisthes cinctipes as a prelude to a comprehensive analysis of genetic structure in this species. The adaptation of some marine communities to low levels of some nutrients has made them susceptible to anthropogenic effects. IMPLICATIONS FOR ADAPTATION TO LAND BY CHARLES R.

All enzymatic activity measurements were corrected for unspecific NADH oxidation. It is concluded that the intensity range over which vision in P. elongatus is maximally sensitive to contrast (the dynamic range) is 2.5-3.0 log units.

The present study investigates the spatial dynamics and life history adaptations of an aggregating species, the New Zealand half crab, Petrolisthes elongatus. Nevertheless, the high LDH and OPDH activity found in P. laevigatus compared to other decapod species (Table 4) suggests it is well adapted to episodic conditions of environmental or physiological hypoxia.

For instance, Hochachka (1980) uses these terms indistinctly, while other authors define hypoxia for different oxygen levels such as: |$\lt 0.023 \ {\rm ml \ O}_{2}{\rm l}^{-1}$| (severe hypoxia; Albert and Ellington, 1985); |$2.9 \ {\rm ml \ O}_{2}{\rm l}^{-1}$| (Dortch et al., 1994); between |$0.7 \ {\rm and} \ 3 \ {\rm ml \ O}_{2}{\rm l}^{-1}$| (Fenchel and Finlay, 1995).
