Abstract

A survey of sea turtle rehabilitation facilities in the United States revealed that 34 facilities released 11,417 sea turtles through 2016. The number of turtles released per time period increased over time, with 80% of releases occurring between 2007 and 2016, 15% between 1997 and 2006, and 5% prior to 1997. Twenty facilities reported a total of 314 first re-encounters and 6 second re-encounters of turtles that had been previously released, including 12 turtles encountered while successfully nesting. Results revealed substantial efforts to rehabilitate sea turtles in the United States, with some rehabilitated turtles surviving for extended periods after release, but with the fate of most remaining unknown. Greater efforts to determine the long-term outcome for a larger proportion of rehabilitation cases are warranted.

Abstract

Adult Podocnemis unifilis were monitored using VHF radio tracking from September 2013 to September 2014 in the Rio Trombetas Biological Reserve, Pará, Brazil. Our aim was to analyze the use of space by this species near the nesting beach base by describing size and overlap of estimated home ranges. Transmitters were attached to 10 males and 10 females. The mean home range size calculated through the fixed-kernel (FK) method with 95% of the fixes was 79.28 ± 77.08 ha (0.56–215.07 ha; n = 13). The mean of overlapping areas was 14% with FK95% (0.02%–81%; n = 13) and 5% with FK50% (0.1%–23%; n = 9). There was a significant difference in the mean overlapping areas between females and males. The analysis of the overlap of activity centers estimated by FK50% is extremely important for the establishment of conservation strategies in the management plan for this species in the reserve. We were able to identify 2 critical areas for the maintenance of this population where there was a frequent overlap of activity centers: the first, identified during the dry season, was composed of small overlaps among 7 turtles and was near the nesting areas on the clay banks within the Lago Jacaré; the second, identified during the rainy season, was composed of a concentration of overlap areas of larger size among 6 turtles and was an open area in the flooded forest. It is important not only to protect the nesting areas during the dry season but also to protect flooded forest areas with the major intensity of use along with the canals that link the flooded forests to the lakes in the rainy season. For conservation purposes, it is necessary to continue the protection of the nesting beaches throughout the savannas inside the lake where the species nests in the dry season. The flooded forest areas that are zones of intense use during the rainy season, and the canals where the turtles can move between lakes must be protected throughout the year.

Abstract

To better understand the habitat preferences of the African spurred tortoise (Centrochelys sulcata), we tested possible associations between their distribution and land use, vegetation cover, the presence of roads, human settlements, and rainfall patterns, all of which affect the distributions of other tortoise species. African spurred tortoise distribution (based on 36 presence points compared with 250 random points) was strongly associated with 3 variables we analyzed: 1) Corine Land Cover (CLC) categories (especially sites with deciduous shrubs and high herbaceous cover relative to random bare areas), 2) distance from human settlements, and 3) distance from the nearest road.

Editorial Introduction. — This section is devoted to poetry involving turtles, representing either reprinted previously published or new unpublished material. We encourage our readers to submit poetry or songs for consideration, either their own material or work by other authors. Poems may be submitted to Anders G.J. Rhodin, Chelonian Research Foundation, E-mail: RhodinCRF@aol.com.

Our desire is to share with our readers the beauty and wonder of turtles as expressed through the art of the poem or song. In the sense that the relationship between man and turtles is multifaceted, so too is turtle poetry. The poems we
