Using a high resolution cosmological simulation of reionization we have examined the differing structures formed by gas and dark matter at a redshift of 5.1. Baryon-rich regions form a small number of filaments, which connect the largest galaxies in the simulation. More detailed examination of the ten largest galaxies reveals long, slender gaseous filaments about 5 proper kpc in width radiating...

We describe and illustrate two new species of Atanatolica from Brazil and Peru, representing the first record of the genus from Peru and the first record of the genus from Ceará state, Brazil. Atanatolica nordestina sp. nov. is recognized by short inferior appendages, with their basal portions subquadrangular, in ventral view; and by tergum X without the typical digitate apical processes, but w...

A new legume species from a seasonally dry forest of the Western Río Balsas Depression, in the states of Guerrero and Michoacán, Mexico, Erythrostemon guevarafeferii, is herein described and illustrated. The new species shows morphological affinities with Erythrostemon hintonii, from which it is distinguished in having fewer leaflets per pinna, mature leaflets disposed toward the upper half of ...
