Sunspots: from small-scale inhomogeneities towards a global theory

The penumbra of a sunspot is a fascinating phenomenon featuring complex velocity and magnetic fields. It challenges both our understanding of radiative magneto-convection and our means to measure and derive the actual geometry of the magnetic and velocity fields. In this contribution we attempt to summarize the present state-of-the-art from an observational and a theoretical perspective.Comment: Accepted for publication in Space Science Review

Range extensions along western Atlantic for Epialtidae crabs (Brachyura, Majoidea) genera Acanthonyx Latreille, 1828 and Epialtus H. Milne Edwards, 1834

The present study provided information extending the known geographical distribution of three species of majoid crabs, the epialtids Acanthonyx dissimulatus Coelho, 1993, Epialtus bituberculatus H. Milne Edwards, 1834, and E. brasiliensis Dana, 1852. Specimens of both genera from different carcinological collections were studied by comparing morphological characters. We provide new data that extends the geographical distributions of E. bituberculatus to the coast of the states of Paraná and Santa Catarina (Brazil), and offer new records from Belize and Costa Rica. Epialtus brasiliensis is recorded for the first time in the state of Rio Grande do Sul (Brazil), and A. dissimulatus is reported from Quintana Roo, Mexico. The distribution of A. dissimulatus, previously known as endemic to Brazil, has a gap between the states of Espírito Santo and Rio de Janeiro. However, this restricted southern distribution is herein amplified by the Mexican specimens

La cinquena edició del microrelatari per l’eradicació de la violència contra les dones de l’Institut Universitari d’Estudis Feministes i de Gènere «Purificación Escribano» de la Universitat Jaume I vol ser una declaració d’esperança. Aquest és el moment en el qual les dones (i els homes) hem de fer un pas endavant i eliminar la violència sistèmica contra les dones. Ara és el moment de denunciar el masclisme i els micromasclismes començant a construir una societat més igualitària. Cadascun dels relats del llibre és una denúncia i una declaració que ens encamina cap a un món millor

New records of caridean shrimps, Lysmata ankeri and L. cf. intermedia, from southeast coast of Brazil

34Made available in DSpace on 2019-09-11T20:51:31Z (GMT). No. of bitstreams: 0 Previous issue date: 2016Background: The genus Lysmata includes about 40 described species of which at least 12 species occur in the western Atlantic. The present study records the extension of the southern limit of distribution of two species of Lysmata to the coast of São Paulo. Results: A total of 17 and two individual of Lysmata ankeri and Lysmata cf. intermedia were sampled, respectively. Lysmata ankeri were observed inhabiting crevices and natural burrows formed by rocks from 5 to about 15 m depth, while Lysmata cf. intermedia were found living under a large rocky plate from 8 meters depth. Conclusions: These new records improve our knowledge about the geographical distribution of Lysmata ankeri and Lysmata cf. intermedia. The expansion of the geographical distribution of these species may be caused by two different mechanisms of larval dispersal, either natural or anthropogenic. © 2016 The Author(s).De Paiva Barros-Alves, S., Universidade Federal de Sergipe, UFS, Laboratório de Carcinologia, São Cristóvão, Sergipe, BrazilAlves, D.F.R., Universidade Federal de Sergipe, UFS, Laboratório de Carcinologia, São Cristóvão, Sergipe, BrazilHirose, G.L., Universidade Federal de Sergipe, UFS, Laboratório de Carcinologia, São Cristóvão, Sergipe, BrazilCobo, V.J., Universidade de Taubaté, UNITAU, Laboratório de Biologia Marinha, LabBMar, Instituto de Biociências, Taubaté, São Paulo, Brazi
