“…In winter, dive times were longer but also more variable, and included single dives that lasted almost 2 hours. made for green turtles, Chelonia mydas, and Kemp's ridley turtles, Lepidochelys kempi (Moon et al, 1997). The increase in dive duration with decreasing water temperature probably resulted directly from reduced oxygen consumption, and thus a lower metabolic rate, at low temperatures (Lutz et al, 1989).…”

“…Therefore, in addition to the seasonal metabolic rate depression, heat increment following feeding was probably also reduced, minimising the oxygen consumption even more. Finally, as can be seen from the long resting dives, the loggerhead turtles were also less active at low temperatures (see also Moon et al, 1997). This recalls the often reported temperature effect on activity and food consumption in ectotherm animals (Schmidt-Nielsen, 1990), and could suggest that sea turtles in the wild enter a kind of winter dormancy during which energy requirements are minimal.…”

SUMMARY:We characterised the effect of seasonal fluctuations in water temperature (T w ) on the nonventilatory period (NVP) of Mediterranean loggerhead turtles, Caretta caretta. Ten captive turtles, that were subject to the natural variations in T w found in the Gulf of Naples, dived significantly longer when T w decreased. More than 50% of summer and winter dives lasted between 2 and 10 min; the maximum dive duration (120 min) occurred in winter at a T w of 13°C. The longest NVP coincided with a low level of activity and a lower food consumption. This, and a reduced metabolic rate consequent to acclimatisation to a low T w were likely to have influenced NVP. -En el presente estudio se caracterizó el efecto de la fluctuación estacional en la temperatura del agua (T w ) sobre el periodo no ventilatorio (NVP) de la Tortuga Boba del Mediterráneo, Caretta caretta. Diez tortugas mantenidas en cautividad fueron sometidas a las variaciones naturales de la T w del Golfo de Nápoles, la inmersión fue significativamente más larga cuando la T w decrecía. Más del 50% de las inmersiones, tanto en verano como en invierno, duraron entre 2 y 10 minutos; la inmersión de máxima duración (120 minutos) ocurrió en invierno a una T w de 13°C. El más largo NVP coincidió con el bajo nivel de actividad y el menor consumo de alimento. Ésto, y el reducido grado metabólico como consecuencia de la aclimatación a la baja T w probablemente influyeron en el NVP.Palabras clave: tiempo de inmersión, efecto de temperatura, tortuga marina, apnea.

“…He also suggested that a rapid decline in water temperature stimulated winter migration southward and that the critical temperature range for the migratory response may vary with latitude (cooler in the north and warmer in the south). Moon et al ( 1997) observed that Kemp's ridleys raised in captivity displayed a "hyperactive response" (continuous movement of the foYeflippers) when exposed to water temperatures of 20-15 C, and this behavior may be indicative of a migratory response. Kemp's ridley turtles in Long Island Sound exhibited nondirected movements suggestive of foraging behavior from July to Sept. when water temperatures were > 15 C (Morreale and Standora, 1998).…”

“…Captive Kemp's ridleys stopped feeding when water temperatures fell below 15 C (Moon et al, 1997) and became cold-stunned (immobilized and floating at the surface) at 10-13 C (Schwartz, 1978). Epperlyetal.…”

“…Captive-raised Kemp's ridleys changed their breathing pattern from single breaths to multiple breaths, thus spending more time at the surface, and also exhibited longer surface durations when water temperature was reduced to <20 C (Moon et al, 1997). The submet~ gence durations of a turtle migrating along the U.S. Atlantic coast were significantly longer in winter than in spring (Gitschlag, 1996).…”

Interpretation and implementation of the Convention Species trade and conservation issues TORTOISES AND FRESHWATER TURTLES 1. This document has been prepared by the Secretariat. 2. At its 11th meeting (CoP11, Gigiri, 2000), the Conference of the Parties adopted Resolution Conf. 11.9 on the Conservation of and trade in tortoises and freshwater turtles, and amended it at its 12th and 13th meetings (CoP12, Santiago, 2002; CoP13, Bangkok, 2004). 3. In paragraph m) of Resolution Conf. 11.9 (Rev. CoP13), the Conference of the Parties urges range States of tortoises and freshwater turtles that authorize trade in these species to include in their periodic reporting under Article VIII, paragraph 7 (b), of the Convention information on progress in implementing this Resolution. 4. At its 14th meeting (CoP14, The Hague, 2007), the Conference of the Parties adopted the following Decisions: Directed to Parties 14.126 Parties should liaise with the World Customs Organization to promote the establishment and use of specific headings within the standard tariff classifications of the Harmonized System for tortoises and freshwater turtles and for products thereof. Directed to the Secretariat 14.127 The Secretariat shall submit a written summary of the information on the implementation of Resolution Conf. 11.9 (Rev. CoP13) that is contained in biennial reports from Parties for consideration at the 15th meeting of the Conference of the Parties (CoP15). 14.128 The Secretariat shall, subject to external funding, contract the Tortoise and Freshwater Turtle Specialist Group of the IUCN Species Survival Commission to undertake a study which would assist in the implementation of Resolution Conf. 11.9 (Rev. CoP13). Directed to the Animals Committee 14.129 The Animals Committee shall review the study and make recommendations at CoP15. Regarding Decision 14.126 5. The Conference of the Parties has previously called for WCO to create specific headings for certain CITES-listed taxa in the standard tariff classifications of the Harmonized System. Those requests that were channelled through the CITES Secretariat have not been implemented to date. This might be because WCO normally deals with the Customs authorities of its member countries on these matters, and not with CITES authorities. The Secretariat reported at CoP14 (see document CoP14 Doc. 57) that the process for CoP15 Doc. 49-p. 2 creating new codes within the standard tariff classifications of the Harmonized System takes about seven years from the time of proposal to its coming into effect. Regarding Decision 14.127 6. For reasons of efficiency, the Secretariat incorporated the report, mentioned in Decision 14.127 within the Memorandum of Understanding (MoU) between the Secretariat and the IUCN Species Survival Commission, Tortoise and Freshwater Turtle Specialist Group (IUCN-TFTSG) mentioned in Decision 14.128. Under the terms of reference of the MoU for this work, the Secretariat requested IUCN-TFTSG to examine and analyse details from biennial reports on progress in the implementation...
