Population biology and secondary production of the stout razor clam Tagelus plebeius (Bivalvia, Solecurtidae) on a sandflat in southeastern Brazil

The population biology and production of the stout razor clam Tagelus plebeius Lightfoot, 1786 were investigated on an intertidal sandflat on the southeast coast of Brazil (Enseada Beach, São Sebastião, state of São Paulo) between April 1997 and April 1998. Two rectangular sites of 50 X 10 m parallel to the waterline were established, site A (upper intertidal level) and site B (middle intertidal level), where the samples were taken in an 0.5 x 0.5 m quadrat. High abundances were recorded in winter and spring, with no significant differences between the sites. The high bivalve abundances were related to the presence of very fine homogeneous sediment with low salinities. Tagelus plebeius had negative allometric growth, characteristic of deep burrowers for the relationships DM/SL and AFDM/SL. Parameters of the modified von Bertalanffy growth function were: L∞ = 67.01 mm, K = 1.73 year-1, t0 = -0.11 year, C = 0.43, WP = 0.96. The instantaneous mortality (Z) was 3.12 year-1, relatively high in comparison to other tropical bivalve populations. Secondary production was 1.53 g AFDM m-2 year-1, with a P/B ratio reaching 1.37 year-1. This high turnover ratio (P/B) was related to a rapid population replacement, connected with the short life span and high mortality of the species.546

On the Impact of Tsallis Statistics on Cosmic Ray Showers

We investigate the impact of the Tsallis nonextensive statistics introduced by intrinsic temperature fluctuations in p-Air ultrahigh energy interactions on observables of cosmic ray showers, such as the slant depth of the maximum Xmax and the muon number on the ground Nμ. The results show that these observables are significantly affected by temperature fluctuations and agree qualitatively with the predictions of Heitler model

Revised and extended analysis of five times ionized xenon, Xe Vi

A capillary discharge tube was used to record the Xe spectrum in the 400-5500 Å region. A set of 243 lines of the Xe VI spectrum was observed, and 146 of them were classified for the first time. For all known lines, we calculated the weighted oscillator strengths (gf) and weighted transition probabilities (gA) using the configuration interaction in a relativistic Hartree-Fock approach. The energy matrix was calculated using energy parameters adjusted to fit the experimental energy levels. Core polarization effects were taken into account in our calculations. Experimental energy values and calculated lifetimes are also presented for a set of 88 levels. From these levels, 32 were classified for the first time and 33 had their values revised. Our analysis of the 5s5p5d and 5s5p6s configurations was extended in order to clarify discrepancies among previous works216

Avaliação de genótipos de feijão-caupi de porte ereto e semiereto na safrinha em Botucatu-SP.

O objetivo deste trabalho foi avaliar o ciclo e produtividade de 20 genótipos de feijão-caupi, sendo 16 linhagens e 4 cultivares, identificando os genótipos mais produtivos e bem adaptados. Foram realizados dois experimentos nos anos de 2011 e 2012, em condições de safrinha, em Botucatu-SP. Os genótipos foram avaliados quanto aos seguintes caracteres: número de dias para o florescimento, número de dias para a maturação e produtividade de grãos (kg ha-1). Dentre os materiais avaliados em 2011, as cultivares BRS Cauamé e BRS Tumucumaque e as linhagens MNC02-675F-4-2, MNC02-675F-9-2, MNC02-675F-9-3, MNC02-684F-5-6, MNC03-737F-5-1, MNC03-737F-5-11, MNC03-737F-11 se mostram altamente produtivas. Em 2012 os materiais com maior produtividade foram as linhagens MNC02-675F-4-2 e MNC02-675F-9-2. Os resultados obtidos sugerem que é possível selecionar genótipos produtivos, para cultivo no período da safrinha, na região de Botucatu-SP.CONAC 2012.
