- Coastal Habitat Degradation and Green Sea Turtle Diets in Southeastern Brazil.(Marine Pollution Bulletin, 2011-06) SANTOS, R. G; MARTINS, A. S; FARIAS, J. N; HORTA, P. A; PINHEIRO, H. T; TOREZANI, E; BAPTISTOTTE, C; SEMINOFF, J. A; BALAZS, G. H; WORK, T. MTo show the influence of coastal habitat degradation on the availability of food for green turtles (Chelonia mydas), we assessed the dietary preferences and macroalgae community at a feeding area in a highly urbanized region. The area showed low species richness and was classified as degraded. We examined stomach contents of 15 dead stranded turtles (CCL = 44.0 cm (SD 6.7 cm)). The diet was composed primarily of green algae Ulva spp. (83.6%). In contrast, the macroalgae community was dominated by the green alga Caulerpa mexicana. We found a selection for red algae, seagrass and Ulva spp., and avoidance for C. mexicana and brown alga Dictyopteris delicatula. The low diversity of available food items, possibly a result of environmental degradation, likely contributed to the low dietary diversity. The nutritional implications of this restricted diet are unclear.

- Nesting Biology and conservation of the leatherback sea turtle (Dermochelys coriacea) in Espírito Santo State, Brazil, 1988-1989 to 2003-2004.(Chelonian Conservation and Biology, 2007-05-01) THOMÉ, J. C. A; BAPTISTOTTE, C; MOREIRA, L. M. P; SCALFONI, J. T; ALMEIDA, A. P; RIETH, D. B; BARATA, P. C. RIn Brazil, the only area where regular leatherback sea turtle (Dermochelys coriacea) nesting is known to occur is located on the northern coast of the state of Espı´rito Santo, around latitude 198S. In this study, we present the field methods used by Projeto TAMAR-IBAMA (the Brazilian Sea Turtle Conservation Program) in the state of Espı´rito Santo and analyze data on leatherback nesting from 1988–1989 to 2003–2004. In that period, 527 nests were observed in the study area. The annual number of nests varied between 6 (in 1993–1994) and 92 (in 2002–2003). Between 1995–1996 and 2003–2004, the annual number of nests increased at about 20.4% per year on average. Among the 527 clutches observed, 358 (67.9%) were left in situ, 50 (9.5%) were relocated to another spot on the beach, 88 (16.7%) were relocated to open-air beach hatcheries, and 31 clutches (5.9%) did not have their management decision recorded. Curved carapace length of nesting females was in the range of 139–182 cm (mean ¼ 159.8 cm). At present, there is no significant alteration of the nesting habitat in Espı´rito Santo, egg poaching has been reduced to very low levels, and there is no subsistence hunting for sea turtles of any species. The main challenges to leatherback conservation currently are the incidental capture in artisanal fisheries operating close to nesting beaches and in high seas fisheries operating in the South Atlantic, as well as activities related to the oil industry. An overview of Projeto TAMAR’s actions addressing current sea turtle conservation issues in the State of Espı´rito Santo is presented.
- Restingas:(2023) PEREIRA, SOUZA, K.I.S. M.L.M.; VIEIRA, C.V.A falta de padronização das terminologias das feições costeiras não é problema recente (GUERRA & CUNHA, 1992). O termo restinga, por exemplo, tem sido ponto de diversas controvérsias e variados conflitos na gestão territorial do litoral brasileiro, tendo diferentes significados em diversos ramos das ciências naturais (LACERDA et. al, 1984; SOUZA et. al, 2009)

- The Interplay of Homing and Dispersal in Green Turtles: A Focus on the Southwestern Atlantic(Journal of Heredity, 2012-10-08) NARO-MACIEL, E; BONDIOLI, A.C.V; MARTIN, M; ALMEIDA, A.P; BAPTISTOTTE, C; BELLINI, C; MARCOVALDI, M.A; SANTOS, A.J.B; AMATO, GCurrent understanding of spatial ecology is insufficient in many threatened marine species, failing to provide a solid basis for conservation and management. To address this issue for globally endangered green turtles, we investigated their population distribution by sequencing a mitochondrial control region segment from the Rocas Atoll courtship area (n = 30 males) and four feeding grounds (FGs) in Brazil (n = 397), and compared our findings to published data (nnesting = 1205; nfeeding = 1587). At Rocas Atoll, the first Atlantic courtship area sequenced to date, we found males were differentiated from local juveniles but not from nesting females. In combination with tag data, this indicates possible male philopatry. The most common haplotypes detected at the study sites were CMA-08 and CMA-05, and significant temporal variation was not revealed. Although feeding grounds were differentiated overall, intra-regional structure was less pronounced. Ascension was the primary natal source of the study FGs, with Surinam and Trindade as secondary sources. The study clarified the primary connectivity between Trindade and Brazil. Possible linkages to African populations were considered, but there was insufficient resolution to conclusively determine this connection. The distribution of FG haplotype lineages was nonrandom and indicative of regional clustering. The study investigated impacts of population size, geographic distance, ocean currents, and juvenile natal homing on connectivity, addressed calls for increased genetic sampling in the southwestern Atlantic, and provided data important for conservation of globally endangered green turtles.
