Abstract:Restinga is a coastal ecosystem covering almost the entire Brazilian coast line and it is associated with the Atlantic Forest biome and therefore is a complementary component of the landscape. Its vegetation is highly variable and specialized, being influenced by salt, and with low fertility and moist soil. This environmental landscape promotes the colonization of species from contiguous biomes and ecosystems, thereby promoting high diversity, especially on the northern coast of Bahia. The study was conducted at the Reserva Imbassaí, in the municipality of Mata de São João, northern coast of Bahia, Brazil. We conducted six surveys distributed over one year, with samples every two months; we used the sampling techniques of active visual search, random encounters and pitfall traps along a linear transect. Fourty-nine snakes from 15 species distributed among five families were recorded: Boidae (2), Colubridae (3), Dipsadidae (6), Elapidae (1) and Viperidae (3). Ten of the species of snakes found at Reserva Imbassaí complement the literature overall snakes' list from the north coast of Bahia's restinga. The results show that Reserva Imbassaí is uniquely rich in snakes and therefore represents an important contribution to the knowledge of this taxon within the Atlantic forest hotspot.Keywords: Atlantic forest, boids, colubrids, dipsadids, elapids, northeastern Brazil, squamata, viperids. 2184Portuguese Abstract: A restinga é um ecossistema costeiro, cobrindo grande parte da costa brasileira e é associado ao bioma da Mata Atlântica, agindo como componente complementar da paisagem. Sua vegetação é bastante variada e especializada, influenciada pela salinidade marinha e pela baixa fertilidade e umidade do solo. Estes componentes da paisagem contribuem para a colonização de espécies de outros biomas e ecossistemas próximos, tornando-o assim bastante diverso, principalmente no litoral norte da Bahia. Este estudo foi realizado na Reserva Imbassaí, localizado no município de Mata de São João, litoral norte da Bahia, Brasil. Realizamos seis coletas durante um ano a cada dois meses; utilizamos a procura visual ativa, armadilhas de interceptação e queda e encontros ocasionais em um transecto linear. Foram registradas 49 serpentes de 15 espécies das cinco famílias: Boidae (2), Colubridae (3), Dipsadidae (6), Elapidae (1) e Viperidae (3). Dez destas espécies de serpentes encontradas na Reserva Imbassaí complementam a lista de espécies deste grupo para a restinga do litoral norte da Bahia. Os resultados evidenciam que a Reserva Imbassaí possui uma riqueza única de serpentes e representa uma importante contribuição para o conhecimento deste táxon no hotspot da Mata Atlântica.

Politicians and environmental professionals have pointed to the lack of scientific knowledge to support legislation for planning urban centers. Thus, this essay aims to provide ecological knowledge to assist politicians and environmental professionals in decision making regarding the Brazilian urban zoning. As a science, ecology provides the necessary knowledge to assist the creation of guidelines and standards for urban zoning. Specifically, landscape ecology shows different methods of work, which have as parameters the qualification and quantification of urban environments. These parameters can be used as criteria for planning sustainable cities. The field of urban ecology has demonstrated the importance of conserving green and blue areas (water bodies) in cities, as well as the need for the formation of multidisciplinary teams for urban management and elaboration of public policies pointed to zoning sustainability strategies. Generally, ecology show contributions that assist in the creation of guidelines and norms for Brazilian urban zoning. The suggestions provided through this essay are a starting point for improving the formulation of laws designed to develop and strengthen the legislation on Brazilian urban zoning.

Solifugids have previously been recorded in three Brazilian biomes. The present work extends the records for this order to the Atlantic Forest biome, specifically in restinga (sandy coastal plains) ecosystems. The specimen was identified as Mummucia aff. mauryi Xavier & Rocha, 2001.
