Bionomics and identification of Acromyrmex (Hymenoptera: Formicidae) through an illustrated key

This study is based on sampled data obtained in 60 equally distant municipalities of São Paulo State. In this study, we proposed a tool to identify Acromyrmex species in a practical and agile manner through the use of an illustrated key that demonstrates the morphological attributes of workers, associated with the type of cut plant material, external and internal appearance of nests and nidification sites. Through sampling, eleven species and six subspecies of Acromyrmex occurring in the State were identified, including the first registers of A. diasi and A. subterraneus molestans.

Genetic Diversity in the Modern Horse Illustrated from Genome-Wide SNP Data

Horses were domesticated from the Eurasian steppes 5,000-6,000 years ago. Since then, the use of horses for transportation, warfare, and agriculture, as well as selection for desired traits and fitness, has resulted in diverse populations distributed across the world, many of which have become or are in the process of becoming formally organized into closed, breeding populations (breeds). This report describes the use of a genome-wide set of autosomal SNPs and 814 horses from 36 breeds to provide the first detailed description of equine breed diversity. FST calculations, parsimony, and distance analysis demonstrated relationships among the breeds that largely reflect geographic origins and known breed histories. Low levels of population divergence were observed between breeds that are relatively early on in the process of breed development, and between those with high levels of within-breed diversity, whether due to large population size, ongoing outcrossing, or large within-breed phenotypic diversity. Populations with low within-breed diversity included those which have experienced population bottlenecks, have been under intense selective pressure, or are closed populations with long breed histories. These results provide new insights into the relationships among and the diversity within breeds of horses. In addition these results will facilitate future genome-wide association studies and investigations into genomic targets of selection. © 2013 Petersen et al.

Milton a poem in 2 books: influência e afluência na linguagem poético-visual de William Blake

Sob a influência de seu predecessor mais forte, John Milton, o poeta, pintor e gravurista William Blake reage a essa influência incorporando-a dinamicamente à sua poesia. Porém, a reação à influência poética é mais abrangente que a incorporação do Paradise Lost, de John Milton, ao seu poema Milton: a Poem in Two Books e conduz o autor a criar uma linguagem poética na qual as referências extratextuais verbais e visuais são transferidas, por meio de metalinguagem, para o interior do próprio poema. Sem referências claras para ajudá-lo, o leitor é induzido a criar suas referências subjetivas e dar sentido ao texto, transformando-se, assim, de leitor passivo, em leitor/criador ativo. Palavras-chave: William Blake; iluminuras; John Milton; influência; reação; sistema verbal/visual.

Ilustração: o texto não verbal em livros infantis

This work presents the reading process in yours several levels, emphasizes the aspect of the image reading in children's books aimed at the pre-reader and the initial reader. In the book-image, the narrative text is based on actions involving the characters, time, space and conflict; this text consists of the sequence of illustrations so as to guide the reader by reading the images. Theoretical work enables the production of a book-image authored by researcher and describes the entire creative process until finalization as a physical product
