RESUMO: Antracologia é o estudo do carvão arqueológico ou de origem sedimentar a partir da anatomia do lenho. Uma correta identificação depende de um bom conhecimento da anatomia do lenho e de material de referência adequado. Neste artigo descrevemos a anatomia do carvão de dez espécies nativas que ocorrem na Planície Costeira do Rio Grande do Sul – Lithraea brasiliensis, Schinus polygamus (Anacardiaceae), Ilex dumosa (Aquifoliaceae), Ocotea pulchella (Lauraceae), Myrcia palustris, Myrrhinium atropurpureum (Myrtaceae), Guapira opposita (Nyctaginaceae), Randia ferox (Rubiaceae), Casearia sylvestris (Salicaceae) e Chrysophyllum marginatum (Sapotaceae). A estrutura anatômica da madeira se preservou perfeitamente após carbonização, apesar de ter ocorrido redução de massa e contração anisotrópica. As pequenas variações induzidas por estes fenômenos não interferem na qualidade do carvão nem no potencial de identificação dos taxa. Os resultados obtidos corroboram a viabilidade da identificação taxonômica a partir da anatomia do carvão.ABSTRACT: Anthracology is the study of charcoal from archaeological or sedimentary contexts based on wood anatomy. A proper identification depends on a good knowledge of charcoal anatomy as well as on the availability of appropriate reference material. In this paper we describe the charcoal anatomy of ten woody species that occur at Rio Grande do Sul Coastal Plain (Southern Brazil) – Lithraea brasiliensis, Schinus polygamus (Anacardiaceae), Ilex dumosa (Aquifoliaceae), Ocotea pulchella (Lauraceae), Myrcia palustris, Myrrhinium atropurpureum (Myrtaceae), Guapira opposita (Nyctaginaceae), Randia ferox (Rubiaceae), Casearia sylvestris (Salicaceae) and Chrysophyllum marginatum (Sapotaceae). The wood anatomical structure was perfectly preserved after carbonization, despite mass loss and anisotropic shrinkage. The small variations due to these properties do not affect charcoal quality nor its identification potential. The results here obtained attest of the reliability of taxonomic identification from charcoal anatomy.

This study describes the general, macroscopic and microscopic anatomical structure of the called "Maria-Preta" (Maba inconstans (Jacq.) Gris.), a native tree to the State of Rio Grande do Sul, Brazil. The wood anatomy of this species is compared with the usual literature for this botanical family. It was found a great similarity between the wood of Maba inconstans and the xylology of the genus Diospyros.

Number Of Species

The coastal plain of Rio Grande do Sul state, southern Brazil, presents as characteristic large expanses of wetlands. Some of these environments are of a temporary nature, and thus have a community adapted to periods with water and periods of drought. Among these communities we can highlight the Cladocera, which have the capacity to form structures of dormancy, and due to this adaptation are effective at colonizing these environments. This study aims to identify the Cladocera species present in the temporary aquatic environments of the southern coastal region of Brazil. Samples were collected in 14 temporary aquatic environments using a classical filtering methodology. As results we obtained 64 Cladocera taxa, representing 54% of the total number of species described in Brazil. The number of taxa was high, the species accumulation curve showed a tendency to stabilization, demonstrating that this region possesses a greater richness.

AbstractThe Rio Grande do Sul Coastal Plain (southern Brazil) is composed of extensive marine and continental deposits related to at least four lagoon-barrier systems of Pleistocene−Holocene age. Part of these deposits is currently submerged and passing through erosion processes by waves. Vertebrate and invertebrate body and trace fossils are constantly exhumed from these deposits and redeposited on the modern beach face. Among them, a total of 253 fragments of crustacean burrows were collected for this study. Two ichnospecies of Ophiomorpha Lundgren, 1891 were recognized (O. nodosa Lundgren, 1891 and O. puerilis Gibert et al., 2006), but most of the materials can only be assigned to the ‘SOT’ group (Spongeliomorpha de Saporta, 1887, Ophiomorpha, and Thalassinoides Ehrenberg, 1944), mainly because of the lack of a pelleted lining. The absence of pellets and, as a consequence, the ichnotaxonomy of these specimens, is related to taphonomical processes (exhumation, reworking, and transportation) that acted during formation of the ex situ assemblage. The paleoenvironmental dynamics and a taphonomical model are presented to demonstrate how these processes affected the trace fossils since their construction, through exhumation until deposition. Neoichnological observations led us to infer larger producers in comparison to the extant ghost shrimp Sergio mirim (Rodrigues, 1971).

A New Species

Croton bacupariensis, an endemic species from the coastal plain of the State of Rio Grande do Sul, southern Brazil, is described and illustrated. The new species shares morphological features with Croton gnaphalii, but differs mainly by the habit, indumentum of leaves and morphology of pistillate flowers. In addition; C. gnaphalii occurs all over the Pampa’s grasslands of Argentina, Uruguay and Rio Grande do Sul.
