In nest-building species predation of nest contents is a main cause of reproductive failure and 16 parents have to trade off reproductive investment against antipredatory behaviours. While this trade-off is modified by lifespan (short-lived species prioritise current reproduction, long-lived 18 species prioritise future reproduction), it may vary within a breeding season, but this idea has only...

[1] Data on the distribution of the partial pressure of CO2 (pCO2) were obtained during six cruises off the Galician coast, a region characterized by a seasonal upwelling. The values of pCO2 over the continental shelf are highly variable and range between 265 and 415 matm during the upwelling season and between 315 and 345 matm during the downwelling season. Both the continental shelf and off-s...

Sorghum (Sorghum bicolor (L.) Moench) may be harmlessly intercropped with Urochloa species during the off-season in Brazilian Cerrado. At end of sorghum cycle, forages can used for straw production soybean (Glycine max L.) as summer crop. This study aimed to evaluate cultivated off-season, palisade grass (Urochloa brizantha cv. ‘Marandu’ (Hochst. ex A. Rich). R. D. Webster) and Congo ruziziensi...

Sandy soil often has low organic matter (SOM) content, cation exchange capacity (CEC), and water storage levels. requires specific management techniques to improve quality. The purpose of this study was evaluate chemical characteristics microbial activity sandy soil, as well the effects different rotation systems on crop yield in these environments. treatments consisted cultivation with cover c...

BACKGROUND We have previously reported that asthma differs from rhinitis with or without bronchial hyperresponsiveness in the perception and degree of lower airway inflammation. OBJECTIVE The aim of the present study was to investigate whether sputum levels of inflammatory markers could further distinguish these patient groups. METHODS Patients with seasonal allergic rhinitis with or withou...

Papaya is a tropical crop increasingly cultivated in the greenhouses of subtropical regions such as South East Spain, where determination best planting season important to ensure stable fruit production and quality during year. In this work, we studied plant growth, yield, quality, comparing spring autumn seasons ‘Intenzza’ cultivar. The results showed that favors leading an earlier entry into ...
