Análise faciológica e estratigráfica das formações Taciba (parte superior) e Rio Bonito (membro Triunfo) em poços testemunhados da área de Monte Alegre (PR)

The Triunfo Member, from Rio Bonito Formation, is a potential reservoir for hydrocarbons and water, and contains coal deposits in the northern state of Paraná. On the eastern edge of the Paraná Basin, the Triunfo Member has two depocenters in Santa Catarina and offlap to the North of Paraná; here in two adjacent areas characterized his final lapout. These areas have a number of wells core/logged with the initials MA and NF, Monte Alegre and Figueira North, which were drilled by the Companhia de Pesquisa e Recursos Minerais (CPRM), in order to research for coal in the Rio Bonito Formation. In this study, three wells in the MA area, and they were MA-4, MA-6 and MA-7 was subjected to vertical facies analysis (1D), from the description of wells and processing of data, so that later it was possible to chronocorrelate thereof, together with MA-5 well, through cycles facies (2D). This is a thesis which has never been developed in these wells mentioned above, it was possible to observe the development of part of the Member Taciba (top) and the Member Triunfo as a whole, can be determined three cycles facies to the latter, as well as their depositional environments. Finally, the chronocorrelate showed that there is a tabular architecture between the wells studied, this occurred because of subsidence uniform

Influência de genótipos de couve (Brassica oleracea L. var. acephala DC.) na biologia de Plutella xylostella (L., 1758) (Lepidoptera: Plutellidae)

Objetivou-se, com este trabalho, avaliar a influência de alguns genótipos de couve (Brassica oleracea L. var. acephala DC.) no desenvolvimento de Plutella xylostella (L., 1758) (Lepidoptera: Plutellidae). Os genótipos avaliados foram: Manteiga de Ribeirão Pires I-2620, Roxa I-919, Manteiga de São José, Manteiga de Monte Alegre, Pires 2 de Campinas, Couve Comum, Couve de Arthur Nogueira 2, Couve de Arthur Nogueira 1. Lagartas recém-eclodidas foram mantida em discos foliares de 8 cm de diâmetro para cada genótipo. Foram analisados os seguintes parâmetros: duração e viabilidade das fases larval e pupal, longevidade e fecundidade de adultos, utilizando análises paramétricas e de agrupamentos para interpretação dos dados. Observou-se um prolongamento em dias no ciclo de P. xylostella, aumento no peso de pupa e maiores valores de viabilidade e fecundidade, durante a segunda geração. O genótipo Couve de Arthur Nogueira 2 foi menos favorável ao desenvolvimento de P. xylostella nas duas gerações, e Couve Comum demonstrou maior influência negativa ao inseto na segunda geração. Manteiga de Ribeirão Pires I-2620 foi o mais suscetível nas duas gerações, agrupando com este na segunda geração Pires 2 de Campinas e Manteiga de São José.

Emergência e crescimento inicial de plântulas de Archontophoenix cunninghamiana H. Wendl. & Drude provenientes de sementes de diferentes plantas matrizes

A diversidade genética é um fator fundamental nos programas de melhoramento e seleção de plantas, dessa forma, o objetivo no trabalho foi avaliar genótipos de Archontophoenix cunninghamiana quanto à emergência e crescimento inicial das plântulas, no sentido de orientar a seleção de plantas matrizes. Os frutos maduros foram colhidos em dez plantas matrizes em Monte Alegre do Sul - SP, nos quais se avaliaram o peso e as dimensões e, nas sementes, também o peso e as dimensões, além do teor de água, emergência, índice de velocidade de emergência, diâmetro e comprimento da parte aérea e massa seca de plântulas. O delineamento utilizado foi o inteiramente casualizado e a comparação entre médias foi realizada pelo teste de Tukey (P<0,05). Entre as sementes das matrizes, há diferenças nas características físicas e fisiológicas, o que possibilita a identificação e seleção de matrizes produtoras de sementes de qualidade superior.

Behavioral study of Cebus nigritus (Goldfuss, 1809) (Primates, Cebidae) in captivity

The objective of this study was to describe the behavior of Cebus nigritus kept in captivity. The work, carried out during the month of March 2008 at "Dr. Belrio Guimaraes Brandao" County Zoo in GarYa- SP and Monte Alegre Farm Ecological Park in Telemaco Borba- PR, included 48 hours of observations, divided equally in four daytime periods. The behavioral catalogue used was constituted of different categories such as: foraging, feeding, locomotion, rest, social interaction, physical care, alertness, manipulation of things, reproductive behavior and stereotyped behavior. Animals showed activities of foraging, feeding, and locomotion and social interaction in low percentages in the two morning periods; however, their frequencies increased in the afternoon. Other activities like physical care, alertness and stereotyped behavior appeared mainly in the two morning periods, but were reduced in the afternoon. The rest category was more evident early morning and late afternoon. Since the stereotypical behavior presented high percentages, this study recommends that the number of individuals be diversiied in the social organization of the groups and that environment enriching activities be developed in captivity, creating situations similar to the animal's natural habitat.

Permian stromatolites associated with bivalve coquina beds-Angatuba, SP, Brazil (Teresina Formation, Parana Basin)

Silicified stromatolites have been described in the Permian Teresina Formation, Passa Dois Group, of the Parana Basin. These stromatolites occur as blocks in the Fazenda Monte Alegre area at the headwaters of the creek known as Corrego Catanduva in the municipality of Angatuba. These blocks originate from the Serra de Angatuba region and were recognized in a road that was cut in the midst of sandstones and siltites. The stromatolites are isolated bioherms that are domed to subspherical with a flat base in profile and a rounded to lenticular shape in plan view. The stromatolites exhibit a reddish coloration and are composed of microcrystalline quartz. Lamination is continuous, non-columnar, and anastomosed, showing parallel to divergent growth; however, divergent columns also occur, especially at the tops of the bioherms. The lamination is fine and well preserved, with alternating light and dark laminas. Microfossils of filamentous cyanobacteria are preserved and were related to the genera Microcoleus and Rivularia. Silicified bivalves occur in association with the stromatolites and are preserved in the form of coquina beds and rare isolated specimens within the bioherms. The described specimens belong to the Pinzonella illusa biozone, with representatives of the species Pinzonella illusa, Angatubia cowperesioides, and Houldausiella elongata. The formation environment of these stromatolites is associated with tidal plains of shallow, brackish, relatively calm, warm waters of good luminosity with the presence of weak currents. There was likely a low level of predation, and the environment may have been hypersaline. The coquina beds associated with the stromatolites indicate a probable proximal tempestite, i.e., they were formed near the coastline. The stromatolites were originally composed of carbonates, although these were replaced by silica during early diagenesis.

Mesocosm experiment on the impact of invertebrate predation on zooplankton of a tropical lake

Invertebrate predation on zooplankton was investigated in mesocosms in the shallow tropical Lake Monte Alegre, Sauo Paulo State, Brazil, in the summer of 1999. Two treatments were applied: one with natural densities of prey and the predators Chaoborus brasiliensis and the water mite Krendowskia sp. (Pr+), and another without predators (Pr-). Three enclosures (volume: 6.6 m(3) of water per enclosure) per treatment were installed in the sediment of the deepest area of the lake (5.0 m). At the beginning, Chaoborus larvae were present in Pr- enclosures, because of technical difficulties in preventing their entrance, but they virtually disappeared in the course of the experiment. Water mites were almost absent in Pr- enclosures. Chaoborus predation negatively influenced the Daphnia gessneri population, but not the populations of the copepods Tropocyclops prasinus and Thermocyclops decipiens and the rotifers Keratella spp. Death rates of Daphnia were generally significantly higher in the Pr+ treatment; Daphnia densities increased after the disappearance of Chaoborus in Pr-. Copepod losses to predation in the experiment may be compensated by higher fecundity, shorter egg development time, and lower pressure on egg-bearing females, resulting in a lower susceptibility to Chaoborus predation. The predation impact of water mite on microcrustaceans and rotifers in the experiment was negligible.
