Zooplankton abundance and euphausiid community composition were sampled seasonally (spring, summer, fall) within Monterey Bay, California, between 1997 and 1999. Measurements of sea surface temperature (SST), mixed layer depth, and upwelling indices provided concurrent data on physical oceanographic parameters. Both total zooplankton and krill abundance dramatically declined in the summer of 19...

Monoclonal antibodies have been generated against cell surface components of the unicellular phytoflagellate Apedinella radians (Pedinellophyceae). One monoclonal antibody, designated Arg 1E5/1B1, labels a scale associated protein (SAP) of 145 kDa. Immunofluorescence microscopy of whole cells as well as immunoelectron microscopy of whole cell mounts and thin sections using Arg 1E5/1B1 have show...

The in vitro activities of eight antifungal drugs against 106 clinical and environmental isolates of waterborne and cutaneous Exophiala species were tested. The MICs and minimum effective concentrations for 90% of the strains tested (n = 106) were, in increasing order, as follows: posaconazole, 0.063 μg/ml; itraconazole, 0.25 μg/ml; micafungin, 1 μg/ml; voriconazole, 2 μg/ml; isavuconazole, 4 μ...

A new polyketide compound 1 and a new naturally occurring chromone derivative 2, along with two known indole alkaloids 3-4 were characterized from the ethyl acetate extract of a soil-derived fungal strain, Exophiala pisciphila PHF-9. The structures of compounds 1-4 were established by detailed spectroscopic analysis and comparison with literature data. The absolute configuration of 1 was determ...

Species Recognition. — The Florida softshell, Apalone ferox, is the largest of the three softshell turtle species found in Florida and has the darkest coloration. It is also the only softshell species found throughout the length of the peninsula. Adults are large to very large (up to 43.6 kg and 73.6 cm carapace length), flat, brown turtles with a cartilaginous shell that is covered by skin rat...

The larva, pupa and male of a new Neotropical chironomid species, Ablabesmyia tucuxi Neubern et Fusari sp. n., are described and illustrated. The larvae were found in freshwater sponge colonies of Drulia uruguayensis Bonetto et Ezcurra de Drago, 1968 and Oncosclera spinifera (Bonetto et Ezcurra de Drago, 1973) in Brazilian savanna streams. The morphological characteristics of the larval head an...

The oil flotation isolation technique has been successfully applied to recover chaetothyrialean black yeasts and relatives from the environment. The selective mechanisms playing a role in isolation are unknown. The fungi concerned are supposed to occupy specialized microniches in nature, taking advantage of (1) oligotrophism. Mineral oil as a main selective agent may be based on (2) hydrophobic...
