Fish–environment Associations in the Coastal Waters of Andros Island, The Bahamas

Synopsis We surveyed fish communities and corresponding environmental conditions at three broadly similar coastal sites of eastern Andros Island, The Bahamas over a summer–winter–summer sequence to assess the relationship between detailed environmental features and fish species patterns. Environmental variables included covers of various benthic flora components, benthic flora diversity, floral canopy height, micro-crustacean diversity and density, water temperature, extent of destructive land-use and extent of invasion by human-introduced exotic terrestrial plants. Correspondence analysis (CA) indicated that spatial (site) differences in environmental characteristics were greater than temporal (seasonal) differences. Detrended canonical correspondence analysis (DCCA) was used to assess the strength of relationships between the environmental characteristics and the distribution patterns of 25 fish species. Environmental features deemed to be most important in influencing fish species patterns included benthic flora canopy height, extent of invasion by exotic terrestrial plants, cover of Batophora oerstedii, cover of Thalassia testudinum, turf cover, water temperature, micro-crustacean diversity, and micro-crustacean density. Based upon similarities in distribution patterns, fish species formed four clusters which, ultimately, reflected similarities in species’ feeding habits and preferences for habitats that likely maximize foraging success. We conclude that fish distribution patterns are related to environmental characteristics, and that anthropogenic coastal activity, by influencing coastal benthic characteristics, may influence the distribution and abundances of fish species in coastal habitats.     

Cape Delil-de-la-Kroiera (Sakhalin Island)—A new nesting point of marine birds

Two kekurs on Cape Delil-de-la-Kroiera (east coast of Sakhalin Island, to the north of Cape Ratmanova) were surveyed on July 16, 2003. Nesting of six species of sea birds was observed: slaty-backed gull (Larus schistisagus), black-legged kittiwake (Rissa tridactyla), common murre (Uria aalge), spectacled guillemot (Cepphus carbo), horned puffin (Fratercula corniculata), and tufted puffin (Lunda cirrhata).Original Russian Text Copyright © 2005 by Biologiya Morya, Blokhin, Tiunov.

Pandemic Serotypes of Vibrio cholerae Isolated from Ships’ Ballast Tanks and Coastal Waters: Assessment of Antibiotic Resistance and Virulence Genes (tcpA and ctxA)

There is concern that ships’ ballasting operations may disseminate Vibrio cholerae to ports throughout the world. Given evidence that the bacterium is indeed transported by ships, we isolated pandemic serotypes O1 and O139 from ballast tanks and characterized them with respect to antibiotic resistance and virulence genes ctxA and tcpA. We carried out concurrent studies with V. cholerae isolated from coastal waters. Of 284 isolates, 30 were serotype O1 and 59 were serotype O139. These serotypes were overrepresented in ballast tanks relative to the coastal waters sampled. All locations, whether coastal waters or ballast tanks, yielded samples from which serotype O1, O139, or both were isolated. There were three groups among the 62 isolates for which antibiotic characterization was conclusive: those exhibiting β-lactamase activity and resistance to at least one of the 12 antibiotics tested; those negative for β-lactamase but having antibiotic resistance; those negative for β-lactamase and registering no antibiotic resistance. When present, antibiotic resistance in nearly all cases was to ampicillin; resistance to multiple antibiotics was uncommon. PCR assays revealed that none of the isolates contained the ctxA gene and only two isolates, one O139 and one O1, contained the tcpA gene; both isolates originated from ballast water. These results support the bacteriological regulations proposed by the International Maritime Association for discharged ballast water.     

H4-isozyme of lactate dehydrogenase in the solution of sodium chloride—4. inhibition by oxalate and oxamate

• 1.1. The inhibition of H4-isozyme of lactate dehydrogenase (H4-LDH) by oxalate and oxamate was studied in 0.5 M sodium chloride. At 20 C. oxalate inhibition was a mixed type and at 40 C, the inhibition was uncompetitive.
• 2.2. Oxamate inhibition was shown as two different types. The inhibition was non-competitive at low pyruvate concentrations and competitive at high pyruvate concentrations. Inhibition type did not differ as temperature changed.
• 3.3. The inhibition mechanism is proposed on the basis of quaternary enzyme complex with two kinds of pyruvate as reported previously. The distribution of ternary and quaternary enzyme complexes may determine the inhibition type.
