摘要。巴西伯南布哥Ipojuca海滩上覆瓦龟的时空分布和繁殖成功。本研究旨在验证Eretmochelys imbricata（Linnaeus，1766）的时空分布及其生殖生物学方面，如孵化时间，生殖成功率，雌性的生物测定，巢数和繁殖力。数据收集于2007年至2010年期间，在Muro Alto、Cecca、Merepe、波尔图de Galinhas和Maracaipe的海滩上，所有这些海滩都位于巴西伯南布哥州的Ipojuca市。比较分析了该物种的生殖生物学参数和营巢面积。在10月至5月期间记录了Eretmochelys imbricata筑巢，当时通过三个季节监测了350个巢。产卵高峰期在1 ~ 3月，也有季节性。巢的数量在季节之间有显著差异。Merepe海滩提出了一个升高的发生率的巢（46巢/公里），如果相比，其他监测的海滩。在繁殖生物学方面，繁殖成功率为65.6%，孵化时间为54 ~ 56天。从59个标本中收集生物测量数据，得出弯曲甲壳长度的平均值为92.5 cm ± 4.5 cm，弯曲甲壳宽度的平均值为83.4 cm ± 5 cm。研究结果可用作资助保育计划，并显示本研究所记录的泳滩可作为
ABSTRACT. Spatio-temporal distribution and reproductive success of Eretmochelys imbricata on the beaches of Ipojuca, Pernambuco, Brazil. This study aimed to verify the spatio-temporal distribution of Eretmochelys imbricata (Linnaeus, 1766) and aspects of its reproductive biology, such as incubation time, reproductive success, biometric measurements of females, number of nests and fecundity. Data were collected during 2007 to 2010, on the beaches of Muro Alto, Cupe, Merepe, Porto de Galinhas, and Maracaipe, all of them located in the city of Ipojuca, state of Pernambuco, Brazil. Parameters relating to reproductive biology and nesting areas of the species were comparatively analyzed. Eretmochelys imbricata was recorded nesting between October and May, when 350 nests were monitored through three seasons. The spawning peak happened from January to March, also revealing a seasonal pattern. The number of nests differed significantly between seasons. The Merepe beach presented an elevated occurrence of nests (46 nests/km) if compared to the other monitored beaches. On the aspects of reproductive biology, the reproductive success was 65,6% and the incubation time interval ranged from 54 to 56 days. Biometric measurements were collected from 59 specimens, resulting in an average of 92,5 cm ± 4,5 for the curved carapace length, and of 83,4 cm ± 5 for the curved carapace width. The results can be used for subsidize conservation plans and demonstrate that the beaches recorded in this study are relevant as nesting areas for
