Ants have been suggested as one of many population pressures sea turtles face potentially affecting nesting-beach survival of eggs and hatchlings. However, little is known about the extent to which ants act as incidental or primary mortality factors. Most research has focused on New World fire ants (genus Solenopsis), with confirmed records of other ant species interactions with sea turtle nests in situ being rare. Our study documented the ant species associated with loggerhead sea turtle Caretta caretta (Linnaeus) (Testudines: Cheloniidae) nests in Georgia and determined if ant presence was linked to lower hatching or emergence success. Samples (n = 116) collected from sea turtle nests on eight islands contained 14 ant species including Solenopsis invicta Buren (Hymenoptera: Formicidae), the red imported fire ant, which was the most common ant species encountered. Ant presence was not correlated with lower hatching success, but when other known disturbances were removed, correlated with significantly lower nest emergence success (P < 0.0001). Logistic modeling suggests that proximity of sea turtle nests to the primary dune significantly increases risk of ant predation on hatchling sea turtles. Population managers can reduce this risk by maintaining a 1-m buffer shoreward between dune vegetation and relocated sea turtle nests. Our results suggest that ants may exert a density-dependent pressure on nesting sea turtle populations and call for additional investigations to determine if managing native and invasive ants augments other efforts to improve hatchling survival.

本地和非本地蚂蚁的存在与红海龟巢的较低出现成功有关:对管理的影响

蚂蚁被认为是海龟面临的众多人口压力之一,这可能会影响鸡蛋和幼龟在筑巢海滩的生存。然而,关于蚂蚁作为偶然或主要死亡因素的程度知之甚少。大多数研究都集中在新大陆火蚁(Solenopsis 属)上,其他蚂蚁物种与原地海龟巢相互作用的确认记录很少见。我们的研究记录了与红海龟 Caretta caretta (Linnaeus) (Testudines: Cheloniidae) 在乔治亚州筑巢相关的蚂蚁种类,并确定蚂蚁的存在是否与较低的孵化或出现成功率有关。从八个岛屿上的海龟巢穴中采集的样本(n = 116)包含 14 种蚂蚁,包括红火蚁(Solenopsis invicta Buren)(膜翅目:蚁科),这是最常见的蚂蚁种类。蚂蚁的存在与较低的孵化成功率无关,但当其他已知的干扰被移除时,与显着较低的筑巢成功率相关(P < 0.0001)。逻辑模型表明,海龟巢穴靠近主要沙丘会显着增加蚂蚁捕食刚孵化的海龟的风险。人口管理者可以通过在沙丘植被和重新安置的海龟巢之间保持 1 米的海岸缓冲区来降低这种风险。我们的研究结果表明,蚂蚁可能会对筑巢的海龟种群施加依赖于密度的压力,因此需要进行额外的调查,以确定管理本地和入侵蚂蚁是否会增加其他提高孵化存活率的努力。但是当其他已知的干扰被移除时,与显着降低筑巢成功率相关(P < 0.0001)。逻辑模型表明,海龟巢穴靠近主要沙丘会显着增加蚂蚁捕食刚孵化的海龟的风险。人口管理者可以通过在沙丘植被和重新安置的海龟巢之间保持 1 米的海岸缓冲区来降低这种风险。我们的研究结果表明,蚂蚁可能会对筑巢的海龟种群施加依赖于密度的压力,因此需要进行额外的调查以确定管理本地和入侵蚂蚁是否会增加其他提高孵化存活率的努力。但是当其他已知的干扰被移除时,与显着降低筑巢成功率相关(P < 0.0001)。逻辑模型表明,海龟巢穴靠近主要沙丘会显着增加蚂蚁捕食刚孵化的海龟的风险。人口管理者可以通过在沙丘植被和重新安置的海龟巢之间保持 1 米的海岸缓冲区来降低这种风险。我们的研究结果表明,蚂蚁可能会对筑巢的海龟种群施加依赖于密度的压力,因此需要进行额外的调查以确定管理本地和入侵蚂蚁是否会增加其他提高孵化存活率的努力。逻辑模型表明,海龟巢穴靠近主要沙丘会显着增加蚂蚁捕食刚孵化的海龟的风险。人口管理者可以通过在沙丘植被和重新安置的海龟巢之间保持 1 米的海岸缓冲区来降低这种风险。我们的研究结果表明,蚂蚁可能会对筑巢的海龟种群施加依赖于密度的压力,因此需要进行额外的调查以确定管理本地和入侵蚂蚁是否会增加其他提高孵化存活率的努力。逻辑模型表明,海龟巢穴靠近主要沙丘会显着增加蚂蚁捕食刚孵化的海龟的风险。人口管理者可以通过在沙丘植被和重新安置的海龟巢之间保持 1 米的海岸缓冲区来降低这种风险。我们的研究结果表明,蚂蚁可能会对筑巢的海龟种群施加依赖于密度的压力,因此需要进行额外的调查以确定管理本地和入侵蚂蚁是否会增加其他提高孵化存活率的努力。
