El Holoceno medio palustre de la llanura litoral del río Ter (Baix Empordá, Girona)

The paludal deposits presented here belong to a geomorphological unit identified between Palafrugell Corridor and the littoral plains of Ter River (Baix Ter), associated to a carbonate-rich spring system. The sections show a distintic clay level, mixed with black silts, very rich in snail remains. The malacological assemblage contained stillwaters species (Bithynia leachii, Galba truncatula, Pisidium milium, Radix peregra) along with damp species (Monacha cartusiana, Oxyloma elegans, Succinea putris, Succinella oblonga, Vallonia pulchella, Vertigo sp.). Some open-dry species are also present (Cernuella virgata, Eobania vermiculata, Pomatias elegans, Rumina decollata) revailing a mosaic-like landscape. Radiocarbon dates place this level ca. 7.000BPwithin the Holocene sequence of the Baix Ter basin. Colluvial deposits on top of these paludal levels have a typical open-dry malacological assemblage (Cernuella virgata, Cochlicella acuta, Eobania vermiculata, Pomatias elegans, Rumina decollata, Trochoidea elegans) the same assemblage that inhabits the Empordà littoral plains nowadays

Effects of resource limitation on the essential oil production in Ledum palustre ssp decumbens (Ait.) Hultén

To understand the relationship between resource limitation and essential oil production of the widely-distributed boreal/arctic shrub, Ledum palustre ssp decumbens, I documented naturally occurring variation of essential oils over a growing season withfield collections along a latitudinal transect spanning boreal forest to arctic tundra. Collections from a long-term resource manipulation experiment at a single tundra site served as a means of teasing apart those factors that might be influencing the essential oil production of the species. The essential oil composition varied significantly along thetransect in the number of detectable components, but the relationships among resources and essential oil production were complex. In the manipulation experiment, essential oil components varied greatly among the treatments, with significant differences in the qualitative expression of the specific essential oil components. Both studies suggest that future climate changes have the potential for large changes in production and quality of essential oils.

Infecção pelo Plasmodium falciparum e gravidez: relato de casos

Em 1982 e em 1985 foram observados em Humaitá, Estado do Amazonas, respectivamente, uma criança lactente e uma gestante tercigesta, no segundo trimestre da gravidez, ambas com malária pelo Plasmodium falciparum. O lactente, masculino, natural do Amazonas tinha um mês de idade e apresentava malária desde o décimo dia após o nascimento. Sua mãe tinha 19 anos, era natural do Amazonas e apresentara a primo-infecção palustre no dia do parto, desse que era o seu segundo filho. O outro caso era o de uma gestante com 22 anos, natural do Amazonas, que tinha 2 filhos, um de 8 e outro de 6 anos e apresentara três surtos prévios de malária, o primeiro em 1983 e o último em março de 1985. Quando foi atendida estava com malária e no 2º trimestre da gestação. Tanto o lactente, quanto a gestante foram tratados com clindamicina e tiveram cura clínica e parasitária. O lactente provavelmente apresentou malária congênita, ou intraparto, pelo curto período de incubação, que apresentou. Ao contrário do que tem sido descrito em áreas hiperendêmicas a gestante apresentou malária na terceira gestação, embora tenha se comportado como primigesta, do ponto de vista da imunidade, pois os surtos prévios que teve ocorreram após as gestações anteriores.

Revision of the genus Beatogordius (Gordiida, Nematomorpha): II. South american species with description of two new species

Seven species of Beatogordius (Nematomorpha) have been reported from South America. A reinvestigation could not reproduce a number of determinations indicated in the literature. B. deshayesi has been a misinterpretation and the status of B. irregularis appears to be very uncertain, because no generic characters could be found. The descriptions of B. alfredi and B. latastei confirm that these species belong to South America only. In B. abaiconus we found adhesive warts anterior of the male cloacal opening. These structures were to date only known from the genus Gordionus. In the posterior end of females from B. alfredi and B. variabilis, short paired rows of bristles were present which had to date only been known from the African species B. equinatus. Two new species, B. funis and B. palustre could be added to the genus.

Geologia de la Plana del Baix EmpordÃ

The geological features of the Baix Empordà Plain are mainly related to the sedimentary processes that took place during the Holocen, when a stable sea level was reached at the end of the Versilian transgression. In this paper, all the sedimentary environments which have given rise to the present morphology are described: alluvial, coastal and palustrine environments as well as colluvial and aeolian deposits. We conclude with a scheme in which the geological evolution of the Plain is shown
