For the two latter enzymes, specificity tests were conducted with 100 mM of L-serine, L-proline, and L-cysteine substrates. We used the same homogenization method described for the determination of LDH activity in the determination of opines activities. They feed by combing plankton and other organic particles from the water using long setae (feathery hair- or bristle-like structures) on the mouthparts. The species of the genus Petrolisthes produce eggs of higher volume (0.157-0.241 rnm3 compared to Allopetrolisthes spp. This is consistent with the same role assigned by Yu and Woo (1987) to LDH in the brain of Channa maculata. Biotic and abiotic factors affecting the Tasmanian distribution and density of the introduced New Zealand porcelain crab Petrolisthes elongatus. 3). The present study investigates the spatial dynamics and life history adaptations of an aggregating species, the New Zealand half crab, Petrolisthes elongatus, which exhibits a high phenotypic plasticity of reproductive traits in response to the variable environmental conditions across sites.

Activity was estimated following Market and Faulhaber (1965) using an extinction coefficient of |$\varepsilon_{340}= 6.290 \ {\rm mL \ mol}^{-1}{\rm cm}^{-1}$| for |${\rm NADH}^{+}$|. Respiration rates were estimated from the differences in oxygen content between incubation periods. In each experiment, 12 jars were filled with one specimen and sea water while another 12 jars were filled only with sea water to be used as controls. Fifty randomly selected publications dealing with aspects of crustacean vision had theirMaterials and methods sections examined. Related Taxon Records: 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). Its geographic distribution and its location in the intertidal zone suggest that this species should have ample physiological and biochemical adaptability to environmental change. Both treatments and controls were kept at a constant temperature |$(13^\circ {\rm C} \pm 0.2)$| in thermoregulated baths and observations were made until the death of the specimens under hypoxic conditions.
