Title: A New Species of Kritskyia (Dactylogyridae, Ancyrocephalinae) parasite of urinary bladder of Prochilodus lineatus (Prochilodontidae, Characiformes) from the floodplain of the high Paraná River, Brazil Author: Ricardo Massato Takemoto; Maria de los Angeles Perez Lizama; Gilberto Cezar Pavanelli Abstract (summary): A new species of Kritskyia   inhabits the urinary bladder of the "curimba", Prochilodus lineatus   in the floodplain of the high Paraná river. The new species resembles others members of Kritskyia in the following features: haptor lacking anchors and with 14 hooks marginal, posterior male copulatory organ non articulated with the accessory piece and vagina a sclerotized tube. However, it differs from the known species mainly by the shape of the copulatory complex. This is the third endoparasitic monogenean species reported from freshwater Neotropical fish.

Title: Age structure of adult mosquito (Diptera: Culicidae) populations from Buenos Aires Province, Argentina Author: Arnaldo Macia Abstract (summary): In order to detect seasonal trends in the age structure of adult mosquitoes from Buenos Aires province, Argentina, female populations were sampled with CDC traps during 1989-1991 in Punta Lara and La Plata. The mosquitoes were dissected and age-grouped according to ovarian tracheation and ovariolar stages. All Runchomyia paranensis females were parous, suggesting that this species could be autogenous. Aedes albifasciatus showed parous peaks following population peaks, with shorter delays in spring-summmer and longer in fall-winter. Ae. crinifer and Culex dolosus showed wide fluctuations in age structure due to adult emergences during all months. Psorophora ferox showed high population replacement rates. Mansonia indubitans and Ma. titillans have few generations per year during their activity period. This is the first report on age-grading of adults of field mosquito populations from Argentina.

Title: Electronic publishing of scientific journals - the Bioline model Abstract (summary): Australasian Biotechnology, Volume 7 Number 4, July/August 1997, pp.241-244 Electronic publishing of scientific journals - the Bioline model Barbara Kirsop & Brian Kirsop, Code Number: AU97033 Size of Files: Text: 14.7K Graphics: No associated graphics files Introduction The distribution of scientific information using the Internet is a well established mechanism for most of the major public domain databases (GenBank, EMBL, Swissprot etc). By contrast, the electronic distribution of peer reviewed scientific papers is relatively new. However, the rising cost of scientific publications and the diminishing resources of many libraries has created a situation which is restricting the distribution of the results of scientific and technological research.

Title: Effect of incorporating Cassia siamea prunings on maize yield in an alley cropping trial in semiarid Kenya Abstract (summary): African Crop Science Journal Vol.5. No.2, pp. 201-207, 1997 SHORT COMMUNICATION Effect of incorporating Cassia siamea prunings on maize yield in an alley cropping trial in semiarid Kenya D.N. MUGENDI, B.O. MOCHOGE, C.L. COULSON, C.J. STIGTER and F.K. SANG Code Number: CS97026 Sizes of Files: Text: 22.6K Graphics: Line drawings (gif) - 10.8K ABSTRACT The influence of soil-incorporated Cassia siamea prunings on nutrient status of maize leaves, grain and yield was studied in an alley cropping experiment in semiarid Machakos, Kenya, during the 1988 long and short rainy seasons. The trial was established in 1983 and in all the seasons Katumani composite B maize was sown, except in the short rains of 1988 when Hybrid 511 was planted. Plots consisted of 3 cropped alleys between cassia hedges spaced at 3.6 m apart. The hedges were lopped at the beginning of every season (on-set of rains) and the prunings incorporated into the alleys one day before maize seeds were sown. The control plots had no hedges and hence no prunings were incorporated. Incorporation of prunings into the soil increased nutrient concentration in the maize leaves, grains and soil in the treatment plots compared to the controls. Maize grain yield on a per row basis was also higher in the plots that received prunings application compared to the controls. However, on an area basis, the yield increase was insufficient to compensate for the area lost to the Cassia siamea shrubs. Key Words: Agroforestry, hedge row intercropping, cassia shrubs RESUME L'impact des emondes de Cassia siamea inorpores dans le sol sur la production et la composition minerale des feuilles de mais et des grains a ete etudie dans une experimentation de culture en couloirs. Celle-ci a ete organisee en region semi-aride de Machakos au Kenya pendant les grandes et petites saisons pluvieuses de 1988. L'essai a ete mis en place en 1983. Chaque saison, le compose B du mais connu sous le nom de Katumani etait serre, sauf pendant les petites saisons pluvieuses de 1988 lorsque l'hybride 511 etait plante. Les parcelles etaient constituees de 3 allees cultivees entre les haies de cassia distantes entre elles de 3.6 m. Les haies etaient elaguees au debut de chaque saison pluvieuse. Les emonoles etaient ensuite incorporees dans les allees un jour avant la semence des graines. Les parcelles de contrle n'avaient pas de haies; les emondes n'y etaient donc pas incorporees. L'incorporation des emondes dans le sol des parcelles de traitement augmentait la teneur des elements mineraux nutritifs dans les feuilles et les grains de mais. Cela n'etait donc pas le cas dans les parcelles de contrle. La production des grains de mais par rangee s'est egalement averee plus importante dans les parcelles ou les emondes ont ete appliquees que dans celles de contrle. Cependant, en terme de surface la croissance de la production etait insuffisante pour pouvoir compenser la perte de la surface due a la presence des arbustes de Cassia siamea.
