Item Case report: Ingestion of a massive amount of debris by a green turtle (Chelonia mydas) in Southern Brazil(2012) STAHELIN, G.D.; HENNEMANN, M.C.; CEGONI, C.T.; WANDERLINDE, J.; PAES E LIMA, E.; GOLDBERG, D.W.Marine debris is considered any solid waste (plastic, polystyrene, rubber, foam, glass, metal, cloth, and other man-made materials) that enters the marine or coastal environments from any source (Coe & Rogers 2000). The main sources of marine debris are litter carried into the sea from land-based sources in industrialized and highly populated areas and wastes from ships, fishing and recreational vessels (Derraik 2002). However, regardless of the source, marine debris can have serious ecological and economic consequences. These adverse impacts have been documented all over the world. According to Gregory & Ryan (1997), plastic pollution is estimated to represent between 60% and 80% of the total marine debris in the world's oceans. Within just a few decades since mass production of plastic products commenced in the 1950s, plastic debris has accumulated in terrestrial environments, in the open ocean, on shorelines and in the deep sea (Barnes et al. 2009). Every year, many species of marine animals, including sea turtles, marine mammals, seabirds and fish die from becoming entangled or ingesting plastic debris (Laist 1987). According to Carr (1987) sea turtles are particularly prone to eating plastics and other floating debris. Juvenile sea turtles are frequently exposed to pollution in convergence zones and most species are exposed in nearshore habitats, where they feed (Bjorndal et al. 1994). Evidence indicates that the high occurrence of non-food items in sea turtle species may be related to mistaken ingestion of plastics, due to its similarity to prey items (Plotkin et al. 1993), or even to incidental ingestion along with a prey (Tomás et al. 2002).Item Nesting Ecology and Conservation of the Loggerhead Sea Turtle (Caretta caretta) in Rio de Janeiro, Brazil(2012) LIMA, E. P.; WANDERLINDE, J.; ALMEIDA, D. T de; LOPEZ, G.; GOLDBERG, D. W. .; Bryan P. WallaceLoggerhead turtle (Caretta caretta) nesting in the Southwest Atlantic has been monitored for decades, but information from northern Rio de Janeiro State (Brazil) has been lacking until now. In this study, we documented 11,086 nests laid between the 1992/1993 and 2010/2011 nesting seasons (,1000 nests per season) and found significant variations in incubation period and hatching success among in situ and relocated nests. Because loggerhead nests in Rio de Janeiro are presumed to produce a large proportion of male hatchlings because of lower average incubation temperatures, this area is an important component of loggerhead population biology and conservation in Brazil and the southwest Atlantic region.Item Projeto TAMAR’s station in Florianópolis, state of Santa Catarina, southern Brasil(2012) STAHELIN, G. D.; FIELDLER, F. N.; LIMA, E. P.; SALES, G.; WANDERLINDE, J.Projeto Tamar-ICMBio (Tamar), the Brazilian sea turtle conservation program, has been operating since 1982, first in nesting areas and later extending its activities to coastal foraging areas with high levels of incidental captures of sea turtles by artisanal fisheries. Tamar has also maintained a range of activities related to the incidental capture of sea turtles by open sea fisheries (Marcovaldi & Marcovaldi 1999; Marcovaldi et al. 2006). In April 2005, a new Tamar station (27°34'19"S, 48°25'41"W) was orde inaugurated on Barra da Lagoa Beach (Praia da Barra da Lagoa), in Florianópolis, the capital of the state of Santa Catarina, in southern Brazil. The Santa Catarina coast is a foraging area for sea turtles: no regular nestings have been recorded there, although a small number of occasional nestings (by Caretta caretta and Dermochelys infor coriacea) have been observed in that region (Soto et al. 1997; Soto & Santos 2004). The main objective of the Florianopolis station, which is currently Tamar's southernmost station is to reduce the number of incidental captures of sea turtles in coastal and open lengt sea fisheries operating in the region. However, other threats to sea turtles, such as the ingestion of anthropogenic debris, have also captured this station's attention. The objective of this note is to make a short presentation of the conservation work done by the Florianopolis station.- Reproductive biology and conservation of the loggerhead sea turtle Caretta caretta in the northern state of Rio de Janeiro, Brazil(2012) LIMA, E.P.; WANDERLINDE, J.; ALMEIDA, D. T.; LOPEZ, G.G.;; GOLDBERG, D. W.Projeto TAMAR-ICMBio began its activities in northern Rio de Janeiro in 1992, when the Bacia de Campos station was first established. The early fieldwork included mostly nesting surveys as well as beach monitoring and nest protection along 8 kilometers of the northern coast of Rio de Janeiro. Gradually, the size of the monitored area has increased, and since 2004-2005 about 100 km of nesting beaches have been monitored in each season. Currently, the Bacia de Campos station is responsible for the protection of approximately 1000 loggerhead nests per season (approximate average number of nests between 2007-2008 and 2009-2010 nesting seasons).
Item Case report: Lung Spirorchidiasis in a Green Turtle (Chelonia mydas) in Southern Brazil(2013) GOLDBERG, D. W.; STAHELIN, G. D.; CEGONI, C. T.; WANDERLINDE, J.; LIMA, E. P. E.; MEDINA, R. M.; RIBEIRO, R. B.; SILVA, M. A.; CARVALHO, E. C. Q.Spirorchiid trematodes are implicated as an important cause of stranding and mortality in sea turtles worldwide (Stacy et al. 2010). However, the real impact of these parasites on sea turtle health is poorly understood. The complete life cycle of marine spirorchids still remains unknown; however snails or polichaete annelids may serve as intermediate hosts shedding cercariae that penetrate the mucous membranes of sea turtles, which are their final host (Dailey 1992). The adult trematodes inhabit the cardiovascular system, primarily the heart, as well as visceral and mesenteric vessels, where they copulate and oviposit, causing severe vasculitis, parasitic granulomas and thrombosis (Aguirre et al. 1998). Eggs may migrate and lodge in different tissues, where they induce a granulomatous response (Work et al. 2005). The disease is spread when infected turtles shed the parasite eggs in their feces or urine, through the cloaca (Dailey & Morris 1995).- Enriquecimento ambiental para tartarugas marinhas em cativeiro no Museu Aberto do Projeto Tamar em Florianópolis(2013) GOLDBERG, D.W.; CEGONI, C.T.; STAHELIN, G.; WANDERLINDE, J.; GIFFONI, B.; LIMA, E.P.Bem-estar animal pode ser definido como um estado pleno de saúde física e mental, em que o individuo encontra-se em harmonia com o meio que o cerca. No ambiente natural, o animal enfrenta inúmeros fatores bióticos e abióticos que exigem amplo repertório comportamental, permitindo-o reagir às condições impostas em qualquer momento. Por outro lado, o ambiente reproduzido em cativeiro é limitado em vários aspectos e a transferência do animal de seu habitat natural para um ambiente de confinamento pode causar o aparecimento de comportamentos considerados atípicos para a espécie. Animais mantidos em cativeiro são, de forma geral, expostos a um espaço limitado e de pouca estimulação, levando-os a apresentar quadros de estresse, com distúrbios comportamentais e, em muitos casos, imunossupressão e infecções oportunistas. Como alterativa para minimizar o estresse gerado pelo confinamento, a prática do "enriquecimento ambiental", definida como um conjunto de técnicas de manejo que visam melhorar o ambiente físico e social dos animais, vem sendo amplamente difundida. Durante os últimos anos, o TAMAR de Florianópolis vem instituindo um amplo programa de enriquecimento ambiental para as tartarugas marinhas mantidas no Museu Aberto da Barra da Lagoa.

- Variação Latidutinal na Distribuição do Tamanho de Tartarugas-verdes (Chelonia mydas) ao Longo de Parte da Costa Leste da América do Sul(2011-11-27) BARATA, P. C. R.; CARMAN, V. G.; SANTOS, A.

A.; BECKER, J. H.; WANDERLINDE, J.; ROSA, L.; MARCOVALDI, M. A. G.; MELO, M. T. D.; MASCARENHAS, R.; ESTIMA, S. C.; NARO-MACIEL, E.As tartarugas-verdes (Chelonia mydas), após o nascimento nas praias de desova e um período de alguns anos na zona oceânica do mar, realizam, quando juvenis pequenas, uma mudança para a zona nerítica (Musick e Limpus 1997). A transição da zona oceânica para a zona nerítica e a distribuição geográfica de juvenis e adultos pelas áreas de alimentação costeiras ainda são insuficientemente conhecidas, assim como os fatores que as definem. O conhecimento destes aspectos da história natural das tartarugas-verdes, além de nos permitir um melhor entendimento da sua biologia populacional, tem implicações para a conservação da espécie, por possibilitar o estabelecimento de relações mais claras entre áreas geográficas, estágios ontogenéticos das tartarugas, fatores ambientais ou de outra ordem e ações de conservação. A tartaruga-verde atualmente está classificada como Ameaçada pela União Internacional para a Conservação da Natureza (IUCN). A tartaruga-verde tem ampla distribuição na costa leste da América do Sul (Pritchard 1976; Marcovaldi e Marcovaldi 1999; González Carman et al. 2011). Este trabalho tem como objetivo analisar a variação, em larga escala, da distribuição do tamanho (medido pelo comprimento curvo da carapaça, CCC) das tartarugas-verdes ao longo de parte da costa leste da América do Sul, com dados obtidos em áreas costeiras, com vistas a uma melhor compreensão da biogeografia da espécie na região.
