La papa es uno de los cultivos alimenticios más importantes para el Cusco, Perú. Sin embargo, afectado por un gran número plagas que pueden reducir grandemente su rendimiento. Entre problemas se encuentran “gorgojos” (Coleoptera: Curculionidae) que, a pesar numerosos estudios, aún no han sido identificados adecuadamente. El presente proyecto investigación orientó identificar las especies gorgoj...

We examined 35 species of ground and epiphytic lichens, including fruticose, foliose, crustose lichen, as habitats oribatid mites. Observations were carried out in the taiga forests northeast European Russia, 87 from 38 families found. The Crotoniidae, Carabodidae, Oppiidae, Suctobelbidae are most numerous lichens Oribatulidae epiphytes. Micreremidae Licneremaeidae only noted A complex characte...

Aquatic plants anchored in streams are under pressure from various constraints linked to the water flow and display strategies to prevent their damage or destruction. We assume that the responses of aquatic plants to fast-water flow are a manifestation of a trade-off consisting in either maximizing the resistance to damage (tolerance strategy) in minimizing the hydrodynamic forces (avoidance st...

—Padina antillarum (Kützing) Piccone and P. glabra Gaillard are newly reported for Florida. The first species, which has been widely reported from the Indo-Pacific under the name P. tetrastromatica Hauck, has seldom been reported from the Western Atlantic. The type locality of P. antillarum is Trinidad in the Lesser Antilles, and there are reports of its occurrence from Venezuela and Colombia. ...

Contamination of medicinal plant mass with mycobiots is one of the negative factors deteriorating the quality of raw material. In order to evaluate the impact of the yield processing technologies upon the changes of mycobiots in raw material, the mycobiotic conditions of herb hyssop (Hyssopus officinalis L.) raw material were evaluated under various regimes of active ventilation and optimizatio...

The protease produced by Mucor pusillus was recovered from a wheat bran medium by treatment with ammonium sulfate, ethyl alcohol, gel filtration and ion-exchange chromatography. The yield of the enzyme was 55%. The overall increase in the specific activity of the protease was 34-fold. The purified protease was most active at pH 3.8 and 5.6 against hemoglobin and casein, respectively. Optimal hy...

Underwater, the contrast between object and background is much larger reduced with increasing distance between object and observer than in air. For marine predators, such as pinnipeds, it would therefore be advantageous to possess a high sensitivity for brightness differences, since this would increase the distance at which prey can be detected visually. Few studies have examined the brightness...

An aspartic proteinase, Mucor pusillus rennin (MPR), of filamentous fungus Mucor pusillus, is efficiently secreted from a transformant of Saccharomyces cerevisiae containing the intact MPR gene. To test the usefulness of the MPR leader peptide in secretion of heterologous proteins from yeast cells, several plasmids encoding the fusion proteins composed of different parts of the NH2-terminal reg...
