- Adaptive threat management framework: Integrating people and turtles(Springer Science+Business Media Dordrecht 2015, 2015-09-23) Marcovaldi, Maria Ângela G. dei; Silva, Valéria R. F. da; Mitraud, Sylvia F.; Ferraz, Maria L. C. P.; Lima, Eduardo H. S. M.; Melo, Maria Thereza D.; Santos, Armando J. B.; Silva, Augusto César C. D. da; Castilhos, Jaqueline C. de; Batista, Jamyle A.

Gomes da; Becker, José Henrique; Wanderline, Juçara; Pegas, Fernanda de Vasconcellos; Róstan, Gonzalo; Marcovaldi, Guy Guagni deiIn the 35 years since its inception, the Brazilian National Program for the Conservation of Marine Turtles (TAMAR) has had great success in protecting the five species of sea turtles that occur in Brazil. It has also contributed significantly to worldwide scientific data and knowledge about these species’ biology, such as life cycles and migration patterns. TAMAR’s conservation strategies have always relied on a variety of environmental education and social inclusion (EESI) activities highly adapted to the socioenvironmental evolving contexts of its 25 locations distributed across nine states. Diversity and flexibility are critical to enable timely and effective local responses to existing or potential threats to sea turtles. The intuitive, locally adapted, decentralized, and independent way EESI activities have been carried out have generated positive results in the resolution of specific and evolving local problems through the course of the project. This article brings EESI under the same conceptual framework that underlies its conservation approach by adopting an adaptive threat management framework to organize and qualify its educational and social inclusion interventions according to the main categories of threat addressed by TAMAR.
- Challenges and perspectives for monitoring and managing pelagic longline fisheries in Brazil following incidental catches of sea turtles(2019-10-07) Sales, G.; Giffoni, B.The objective of this work was to present the Brazilian experience in the management of the problem: “interaction of sea turtles with pelagic longline fishing”, emphasizing the challenges of implementing routines to obtain systematic data on fishing operations, through onboard observers.
Item Green turtle (Chelonia mydas) nesting on Atol das Rocas, north-eastern Brazil, 1990–2008(2012-04-25) Bellini, C.; Santos, A.J.B; Grossman, A.; Barata, P.C.R.; Marcovaldi, M.A.In this paper, information is presented on green turtle (Chelonia mydas) nesting on Atol das Rocas (Rocas Atoll), north eastern Brazil. The temporal distribution of nesting events per season, annual number of nests, carapace length of nesting females, clutch size, hatching success, incubation period, internesting interval, clutch frequency, observed reproductive life span, and remigration period are reported. The study period included the nesting seasons from 1990 to 2008, but no regular beach monitoring was carried out in 1998 and 1999. Two sorts of methods were applied to the estimation of the annual number of nests in some seasons. Taking into account the estimated annual numbers of nests, the mean annual number of nests in the study period, excluding 1998–1999, was 335 (standard deviation ¼ 139, range ¼ 136–563, N ¼ 17). An analysis of the available data indicates that the average nesting levels at the beginning of the study period (the first five seasons) and at its end (the last five seasons) were roughly the same. The mean curved carapace length of the nesting turtles decreased significantly during the study period, from 115.9 cm in 1990–1992 to 112.9 cm in 2006 –2008. Atol das Rocas was established as a federal biological reserve in 1979, but regular sea turtle conservation activities actually started there in 1990. Since that year, the killing of nesting turtles has ceased, nesting activity by the turtles can proceed in an undisturbed fashion, and their clutches can incubate in a protected environment.Item INTERVALOS INTERNIDAIS DE TARTARUGAS-DE-PENTE (Eretmochelys imbricata) ATRAVÉS DE TELEMETRIA SATELITAL(2018-11) BELLINI, C.; SANTOS, E. A. P; RAMOS, R.; MARCOVALDI, M. A.; SANTOS, A. J. B- Tamar Sings to Celebrate its 30th Anniversary(2010) MARCOVALDI, M. A; LOPEZ, G. G; SOARES, L. S; LOPEZ, MILAGROS; FERREIRA B, M; THOMÉ, J. C; COELHO, C; BELLINI, C; WANDERLINDE, J; SALES, G; BABTISTOTE, C; SANTOS, A; GOMES, B. M; LIMA, E; LIMA, E. PProjeto TAMAR (Brazilian National Sea Turtle Conservation and Research Program) is celebrating its 30th anniversary. To celebrate, TAMAR has enacted many different ways of recounting their stories over the past three decades. Along with books, videos, and exhibitions, TAMAR sings for the general public about the world’s sea turtles and the people who protect them.
