The Determination Of The Apparent Dissociation Constants Of Arsenic Acid In Seawater, Douglas H. Lowenthal, Michael E.Q. Pilson, Robert H. Byrne
The Determination Of The Apparent Dissociation Constants Of Arsenic Acid In Seawater, Douglas H. Lowenthal, Michael E.Q. Pilson, Robert H. Byrne
Marine Science Faculty Publications
The apparent dissociation constants for arsenic acid in seawater, based on a free molal hydrogen scale, were determined in artificial seawater over a range of salinities and temperatures. A comparison between constants determined in a sodium chloride solution and artificial seawater of the same ionic strength suggests that a significant amount of the reactive arsenate in seawater is ion paired with cations other than sodium. Under typical seawater conditions, arsenic acid appears to be less dissociated than its analogue, phosphoric acid. A series of conversion factors was determined so that these constants could also be applied in conjunction with pH …

International Journal of Speleology
Sphaeromicola cebennica juberthiei n. ssp., a cavernicolous ostracod found in the South of France (Système de Cent Fons and Avencas, Herault), is described here. The new subspecies differs from Sph. cebennica cebennica (found in a cave from Ardèche) by the smaller carapace and a reduced distal bristle on the ‘finger” of the male copulatory organ. The affinities and differences between the European Sphaeromicola and Sph. cirolanae from Mexico are discussed. The genus Sphaeromicola is divided into two groups of species: the group topsenti and the group cirolanae. Some observations on the mating process of Sph. Cebennica juberthiei are presented. …
Variation Among Populations Of The Troglobitic Amphipod Crustacean Crangonyx Antennatus Packard Living In Different Habitats I. Morphology, Gary W. Dickson
Variation Among Populations Of The Troglobitic Amphipod Crustacean Crangonyx Antennatus Packard Living In Different Habitats I. Morphology, Gary W. Dickson
International Journal of Speleology
Populations of the troglobitic (i.e., obligatory cavernicole) amphipod Crangonyx antennatus living in two distinct aquatic habitats were examined for possible morphological variation. Collections were made seasonally for one year in six Lee Co., Virginia caves, three with mud-bottom pools and three with small gravel-bottom streams. Environmental parameters thought to influence population variation were recorded for each of the six caves. Body length of mature amphipods was found to be greater in the mud-bottom pool habitats, whereas stream amphipods possessed more first antennal segments per unit body length. Variation was also observed in integument coloration; stream amphipods were characterized by a …
