Seven fungal species (Aspergillus niger, Aspergillus versicolor, flavus, fumigatus, Rhizomucor pusillus, Trichophyton equinum and Rhizopus oryzae) were isolated from the tannery effluent collected at a industry located Challawa industrial estate of Kano State, Nigeria. niger had highest percentage occurrence frequency 36% (31) while least 4% (5). Consequently, recorded mean tolerance indices 1....

--Data are presented on vegetation structure in Least Bell's Vireo (Vireo bellii pusillus) breeding habitats. A discussion of vegetation and several o"ther fac­ tors relevant to breeding success of this endangered species is presented. Recommendations are made for actions to en­ sure the future of the subspecies as a breeding inhabitant of riparian forests.

The intracellular protease extracted from the freeze-dried mycelia obtained after the growth of Mucor pusillus at 30 degrees C in corn steep liquor medium was chromatographed on DEAE-A50. Some characteristics of the protease fractions obtained after ion-exchange chromatography were determined and compared with those of the extracellular proteases reported previously. The mycelia were found to c...

Quantitative data for Doppler-shift compensation by Pteronotus parnellii parnellii were obtained with a device which propelled the bats at constant velocities over a distance of 12 m. The bats compensated for Doppler shifts at all velocities tested (0.1-5.0 ms-1). The main findings were (1) that compensation was usually accomplished by a progressive lowering of the approximately 61 kHz second h...

Etmopterus spinax and Etmopterus pusillus are captured in large quantities in some deep-water ¢sheries along the Portuguese coast and are always discarded. Specimens were collected from February 2003 to May 2004 from deep-water ¢sheries and classi¢ed as mature or immature. Maturity ogives were ¢tted and size at ¢rst maturity estimated for each sex of each species. Both species are late maturing...

Conidia of Penicillium chrysogenum and Penicillium frequentans and sporangiospores of Rhizopus rhizopodiformis, Rhizomucor pusillus, and Mucor racemosus were subjected to partition in aqueous polymer two-phase systems. The partition behavior differed drastically between the conidia of the two Penicillium species and the sporangiospores of the three species of phycomycetes. This difference in pa...
