Small rookeries are rarely evaluated for marine turtles worldwide. Two species of sea turtles (Hawksbill, Eretmochelys imbricata; Leatherback, Dermochelys coriacea) nest on five main beaches of the northeast coast of the Paria Gulf in Venezuela. Population trends using generalized linear models at this rookery were assessed and compared with other small rookeries. Both species showed significant negative nesting trends: Nesting by critically endangered hawksbills decreased over nine seasons 2009–2017 (64–142 nests per year, General Linear Model Slope Value = −0.061; data pooled for five beaches); similarly, vulnerable leatherback nests decreased across the same period in the main beach Los Garzos (0–69 nests/year; GLMSV = −0.34). Besides human and natural predation of the nests, no significant environmental impacts affect the beaches except probably on Obispo Isthmus where a gas pipeline installation interrupted the nesting activity in 2014. Observed changes to the nesting trends in these small rookeries have a collective impact on broader conservation concerns for sea turtles in the region.

小海龟群注定要灭绝吗？委内瑞拉帕里亚湾的筑巢趋势减少

在全球范围内，很少针对小型海龟进行海龟评估。两种海龟（Hawksbill，Eretmochelys imbricata； Leatherback，Dermochelys coriacea）筑巢在委内瑞拉Paria海湾东北海岸的五个主要海滩上。使用广义线性模型对该群体进行了人口趋势评估，并将其与其他小型群体进行了比较。两种物种均显示出明显的负巢趋势：2009-2017年的九个季节中，濒临灭绝的的嵌套减少（每年64-142个巢，一般线性模型坡度值= -0.061；汇总了五个海滩的数据）；同样，Los Garzos主海滩的脆弱棱皮龟巢在同一时期内有所减少（0-69巢/年； GLMSV = -0.34）。除了人为和自然捕食巢穴外，没有其他明显的环境影响影响海滩，除非可能是奥比斯波地峡（Obispo Isthmus），该处的天然气管道设施在2014年中断了筑巢活动。
