First record of the Lesser Snouted Treefrog Scinax nasicus (Cope, 1862) in Brazilian coast and new species records for the state of Rio Grande do Sul / Primeiro registro da perereca-de-banheiro Scinax nasicus (Cope, 1862) na costa do Brasil e novos registros para o estado do Rio Grande do Sul

Abstract Herein, we provide new occurrence records of Scinax nasicus (Cope, 1862) for the state of Rio Grande do Sul, Southern Brazil. All new records here provide are located on Southern half of the state. Besides this, we provide the first record for species in Brazilian coastal zone. Those records improve considerably our knowledge regarding species distribution in Southern Brazil.

Resumo Aqui, nós fornecemos novos registros de ocorrência de Scinax nasicus (Cope, 1862) para o estado do Rio Grande do Sul, Sul do Brasil. Todos os novos registros aqui fornecidos estão localizados na metade sul do estado. Além disso, nós fornecemos o primeiro registro para a espécie na zona costeira brasileira. Esses registros melhoram consideravelmente o nosso conhecimento sobre a distribuição da espécie no Sul do Brasil.

Mobilization of a hobo-related sequence in the genome of Drosophila simulans.

The hobo transposable element can occur under three forms in the Drosophila genome: as a complete element (also called canonical), as internally deleted copies, or as hobo-related sequences (relics). Some evidence indicated that canonical elements and internally deleted copies are recent acquisitions of Drosophila genomes, while the "relics" are old components, normally degenerated and immobile. Here we present the characterization of a hobo-related sequence, found in the genome of a hypermutable strain of D. simulans, which insertion into the white locus raised a de novo white mutation. It is a shorter hobo related element presenting, overall, roughly 18% of divergence at the DNA level from the canonical hobo, with many indels that make clear this element is defective. However, its ITRs and flanking regions are extremely conserved. This is the first hobo "relic" showed to be mobilizable. We suggest, and point up some evidences, toward the idea that this sequence could have been mobilized by the canonical element. The presence of a similar "relic" element in D. sechellia allows us to suggest that these elements have been maintained mobilizable since the time of divergence between these species.
