Abstract

Turtle populations are in decline worldwide, requiring immediate conservation and management actions. For species with broad geographic ranges that cover diverse environmental contexts, region-specific information on declining species could inform more targeted management plans. I examined the ecology of a Spotted Turtle (Clemmys guttata) population in a temporally dynamic wetland system in the Southeastern Plains ecoregion of North Carolina. Turtles selected forested wetlands and streams while avoiding open wetlands and river habitats, but used terrestrial habitats minimally and randomly. Turtles responded to wetland drying by remaining in wetlands and maintaining modest levels of activity during short-duration drying events (< 1 mo), but moved very little during longer droughts (7 mo). Turtles had prolonged active seasons (February-October) as long as wetlands and streams were flooded, with movement rates peaking in late spring at 23.6 ± 3.7 m/d (mean ± standard error). Turtles had large home ranges (14.1 ± 4.3 ha) that often included multiple local stream networks used as movement corridors between forested wetland patches and as activity centers when wetlands dried. I suggest that conservation plans for C. guttata include large management areas that protect a network of streams and adjacent forested swamps in the Southeastern Plains and perhaps other lowland ecoregions in the Southeastern U.S. Because terrestrial habitats were not used for extended refuge during drought, certain low-impact land uses in adjacent terrestrial areas are not likely to negatively impact C. guttata populations, but terrestrial forests would still be important in maintaining overland travel corridors.

美国北卡罗莱纳州时间动态湿地系统中古苔草的空间生态、活动与生境选择
全世界的海龟数量正在下降,需要立即采取保护和管理行动。对于地理分布范围广、覆盖多种环境背景的物种,有关物种减少的区域特定信息可以为更有针对性的管理计划提供信息。我研究了北卡罗来纳州东南平原生态区内一个临时动态湿地系统中斑龟(Clemmys guttata)种群的生态学。海龟选择森林湿地和溪流,避开开放湿地和河流栖息地,但很少和随机地使用陆地栖息地。海龟对湿地干燥的反应是在短时间干旱事件(< 1个月)期间留在湿地并保持适度的活动水平,但在较长时间干旱(7个月)期间很少移动。只要湿地和溪流被淹没,海龟的活动季节(2月至10月)就会延长,移动速度在春末达到峰值,为23.6±3.7 m/d(平均值±标准误差)。海龟有很大的活动范围(14.1±4.3公顷),通常包括多个本地溪流网络,用作森林湿地斑块之间的活动走廊,以及湿地干涸时的活动中心。我建议古塔塔的保护计划包括大型管理区域,以保护东南部平原的溪流网络和邻近的森林沼泽,也许还有美国东南部的其他低地生态区域。因为陆地栖息地在干旱期间不用于长期避难,邻近陆地区域的某些低影响土地使用不太可能对古塔塔种群产生负面影响。但是陆生森林在维持陆上交通走廊方面仍然很重要。

期刊介绍: Herpetological Conservation and Biology was conceived in 2006 out of necessity. In a time when most journals shunned manuscripts that were descriptive or natural history oriented, our journal filled an obvious void. Herpetological Conservation and Biology is still unique today. Although there are an increasing number of open-access electronic journals, we do not charge authors exorbitant fees for the privilege of making their valuable research available to anyone with access to a computer. Herpetological Conservation and Biology has chronicled its inception and growth in a series of published editorials available at the link below.
