Primary production of Utricularia foliosa L., Egeria densa Planchon and Cabomba furcata Schult & Schult.f from rivers of the coastal plain of the State of São Paulo, Brazil

Seasonal variation in gross primary production (GPP) of Utricularia foliosa Linnaeus, Egeria densa Planchon and Cabomba furcata Schult & Schult.f. in rivers of the coastal plain of the state of São Paulo, Brazil was examined in relation to water physico-chemistry. These three species do not affect the multiple uses of the streams and are present throughout the year. The most productive was U. foliosa (maximum production 24.7 mgO(2) g(-1) DW h(-1)), while C. furcata had an intermediate GPP (maximum production 17.5 mgO(2) g(-1) DW h(-1)) and E. densa was lowest at 5.6 mgO(2) g(-1) DW h(-1). Despite the low amplitude of seasonal variation in this south tropical area, the three species showed seasonal variation in the primary production: GPP was positively correlated with photosynthetic active radiation for U. foliosa and E. densa, and there was a negative correlation for C. furcata. For U. foliosa, GPP was positively correlated with temperature and dissolved inorganic carbon and the GPP of C. jurcata was positively correlated with dissolved inorganic carbon.

New species of Ischnocnema (Anura, Brachycephalidae) from the atlantic rainforest of the state of Espirito Santo, Brazil.

We describe a new species of Ischnocnema from Santa Teresa, in the Atlantic Rainforest of the State of Espirito Santo, Brazil. Ischnocnema abdita sp. nov. is a member of the Ischnocnema lactea species series; it differs from other Ischnocnema mainly by presenting small size (adult male SVL 15.7 [plus or minus] 0.49 mm; range 15.0-16.8 mm); small discs on fingers I and II, and elliptical, wider than long, moderate sized discs on fingers III and IV; and finger I slightly smaller than finger II. The new species closely resembles Ischnocnema bolbodactyla, differing from it by presenting upper and lower margins of iris red in life; inguinal region with many yellow blotches in life; posterior region of belly and ventral surfaces of thighs, shanks, and feet roughly marbled with large pale yellow blotches; and hidden dorsal area of thighs dark brown with few large pale yellow blotches.

Aspects of solid state formation and properties of Sn(0.9)Ti(0.1)O(2) system doped with CoO and Nb(2)O(5)

The effect of calcination temperature during the formation of the solid solution Sn(0.9)Ti(0.1)O(2) doped with 1.00 mol % CoO and 0.05 mol % Nb(2)O(5) is presented. The structural characteristics of this system were studied using X-ray diffraction, and the changes in phase formation were analyzed using the Rietveld method. With an increase in calcination temperature, there is increasing miscibility of Ti into the (Ti,Sn)O(2) phase and near 1000 degrees C, and the remaining TiO(2) (anatase) was transformed into the rutile phase. The sintering process, monitored using dilatometry, suggests two mass transport mechanisms, one activated close to 900 degrees C associated with the presence of TiO(2) (anatase) and the second mechanism, occurring between 1200 and 1300 degrees C, is attributed to a faster grain boundary diffusion caused by oxygen vacancies.

Seasonal variation of Alphitobius diaperinus population in broiler facilities in the center-north region of the state of São Paulo

The seasonality of Alphitobius diaperinus population was studied during different seasons during one year, in broiler facilities located in the center-north region of the State of São Paulo. Parasite counting was weekly carried out by the use of traps adapted from the modified model of Arends. During the experimental period, facilities were not submitted to chemical treatment, and the litter was changed between flocks. A lower number of adults and larvae was observed during autumn, with the peak registered in the summer. There was no significant difference between spring and winter averages (adults and larvae), and between spring and summer averages (adults). Average temperatures in the facilities varied from 23.4ºC (winter) to 27.1ºC (spring). The environmentally controlled systems used by the broiler industry provide an adequate habitat for A. diaperinus development. The continuous monitoring of the population of this parasite is essential for designing control strategies, and this can be accomplished by utilizing the traps used in the present experiment.
