The objective of this study was to investigate morphological variation in traits of systematic relevance and the phylogenetic position, ecology, and reproductive biology of the shrimp Lysmata rauli Laubenheimer and Rhyne, 2010 (Caridea: Hippolytidae), described based only on a single specimen collected in Salvador, Bahia, Brazil. We analyzed a total of 89 specimens from Camamu Bay, Bahia (n = 88) and from S3o Vicente estuary, São Paulo (n = 1). Considerable morphological variation was detected in the rostral spine series, number of segments on the carpus and merus of pereiopod 2, number of spiniform setae on the ventrolateral margin of merus and on the ventral margin of propodus of pereiopods 3-5. Importantly, L rauli can be distinguished neither using morphology, nor coloration from the Indo-Pacific L. vittata (Stimpson, 1860). Furthermore, molecular phylogenetic analyses (using the 16S mt DNA fragment) did not reveal any considerable genetic dissimilarities between L rauli and L vittata. Thus, our results clearly indicate that L rauli is not a new species but a junior synonym of L vittata. The high density observed within the structures of oyster farming indicates that the invasive L vittata lives in crowds in Brazil. The studied population was composed of males, hermaphrodites, and transitional individuals (having characteristics of males and hermaphrodites). The above information suggests that L rauli is a protandric simultaneous hermaphrodite, as it has been observed in all species of Lysmata that have been investigated. Lysmata vittata has invaded the southwestern Atlantic and is present in Bahia, Rio de Janeiro and S3o Paulo, Brazil. © The Crustacean Society, 2013. Published by Brill NV, Leiden.

As aves apresentam diversas características que as tornam peças importantes tanto para a educação ambiental, quanto nas tentativas de conservação de habitats. Para isso, levantamentos da composição da avifauna são fundamentais. Assim, realizou-se o levantamento qualitativo das aves que frequentam os espaços de maior circulação de pessoas do Campus de Rubião Junior, UNESP/Botucatu-SP, entre os meses de Março e Outubro de 2009. Adotou-se o método de transectos lineares, através do qual se percorreu dois trajetos distintos, nos horários de maior atividade das aves. As observações foram feitas com o auxílio de binóculos, além de algumas espécies terem sido registradas visual e/ou sonoramente por câmera fotográfica e gravador. Para a identificação das espécies, utilizou-se basicamente guias de campo. Além da lista de espécies, foi possível também calcular as frequências de ocorrência delas. Foram detectadas 67 espécies, distribuídas em 26 famílias, sendo Tyrannidae a mais representativa (15 espécies). O percurso 1 apresentou 13 espécies exclusivas, enquanto o percurso 2, apenas 4. A maioria das espécies (36) apresentou frequência de ocorrência total inferior a 25% e apenas 12 puderam ser consideradas residentes, com frequência de ocorrência total igual ou superior a 75%. Dentre as famílias com mais de um representante, Columbidae apresentou a maior proporção de número de espécies com alta frequência de ocorrência total (> 50%). Os resultados revelaram maior riqueza de espécies na área com maior diversidade de habitats e menor fluxo de pessoas

Atlantic Forest and Cerrado are between the biological richest areas in the world, for that are considered top conservation priorities. Those ecosystems are found at Botucatu region, where it´s extremely fragmented by routes, agricultural areas and urban centres. This fragmentation causes restrictions on animals populations, in particular to medium and large mammals, that needs larger areas to live and also are often hunted. Even isolated and suffering anthropic influences the fragments are fundamental for local biodiversity conservation. We realized a mammal survey on two forest fragments of Atlantic forest transition to Cerrado of Rubião Júnior – Botucatu – SP – Brazil: Santo Antônio Church and Parque das Cascatas forests. The Santo Antônio church munt is considered a turistic point and its forest receive many visitants, Parque das Cascatas forest is inside of a residential condominium. Both areas are classify as semidecidual stational forest and are disconected by Domingos Sartori route, that connect Botucatu centre to Rubião Júnior district. Around both fragments can be found residences, plantations and pastures. The utilized method included: recognition of tracks on the forests, interviews with next residents and sand plots mounting. The interviews indicated 29 mammals species, and 19 was validated for animal traces, overruns or visualization. Other 3 species found were not mentioned on interviews. Totally, was found 22 small and medium mammals presence evidences on both forest fragments. Parque das Cascatas forest showed more diversity (19) then Santo Antônio Church forest (11), and species like Eira barbara, Procyon cancrivorus, Mazama americana, Shiggurus villosus, Dasypus novemcinctus, Didelphis albiventris, Lutreolina crassicaudata and Lepus europaeus looked for other areas once that was verifyed overruns of individuals...
