Abstract

Inadequate shoreline management might be detrimental to semiaquatic ground-dwelling taxa that utilize shorelines for migrations, basking and nesting sites. Although turtles are often associated with shorelines, limited knowledge of their climbing abilities hinders adequate management of these habitats. In this study we tested the climbing abilities of adult Emys orbicularis (N = 60) to explore the effect which artificial shorelines could have on their dispersal and habitat use. Over 90% of turtles were able to successfully climb a 36° slope. At steeper inclinations, female climbing success drastically dropped. Furthermore, climbing steeper inclinations is more time and energy consuming and might limit habitat use. Our results suggest that body size is the limiting factor of turtle climbing ability, regardless of sex. However, larger and less agile female turtles are especially susceptible to steep shorelines, since their fitness directly depends on their ability to reach favourable nesting sites. Based on our results, we suggest that slopes of artificial shorelines in European pond turtle habitats should not exceed 36° angles. Additionally, the shoreline surface should be textured (e.g. with grooves). Further studies should focus on locomotor abilities of other semiaquatic, ground-dwelling taxa (e.g. newts, toads, turtles), particularly as they pertain to obstacles around their reproductive centres.

欧洲池龟的攀爬能力在陡于 36° 的斜坡上急剧下降:对海岸线管理的影响
海岸线管理不当可能会对利用海岸线进行迁徙、晒太阳和筑巢的半水栖地栖类群造成损害。虽然海龟经常与海岸线打交道,但由于对它们攀爬能力的了解有限,因此无法对这些栖息地进行适当的管理。在这项研究中,我们测试了Emys orbicularis成龟(N = 60)的攀爬能力,以探索人工海岸线对其扩散和栖息地利用的影响。超过90%的海龟都能成功爬上36°的斜坡。在更陡的斜坡上,雌龟的攀爬成功率急剧下降。此外,攀爬更陡的斜坡需要消耗更多的时间和精力,可能会限制栖息地的利用。我们的研究结果表明,无论龟的性别如何,体型都是龟攀爬能力的限制因素。然而,体型较大、灵活性较差的雌龟特别容易受到陡峭海岸线的影响,因为它们的体能直接取决于它们到达有利筑巢地点的能力。根据我们的研究结果,我们建议欧洲池龟栖息地的人工海岸线坡度不应超过 36°。此外,海岸线表面应具有纹理(如凹槽)。进一步的研究应侧重于其他半水栖、地栖类群(如蝾螈、蟾蜍和龟)的运动能力,特别是与它们生殖中心周围的障碍物有关的能力。

期刊介绍: Ecological engineering has been defined as the design of ecosystems for the mutual benefit of humans and nature. The journal is meant for ecologists who, because of their research interests or occupation, are involved in designing, monitoring, or restoring ecosystems, and can serve as a bridge between ecologists and engineers. Specific topics covered in the journal include: habitat reconstruction; ecotechnology; synthetic ecology; bioengineering; restoration ecology; ecology conservation; ecosystem rehabilitation; stream and river restoration; reclamation ecology; non-renewable resource conservation. Descriptions of specific applications of ecological engineering are acceptable only when situated within context of adding novelty to current research and emphasizing ecosystem restoration. We do not accept purely descriptive reports on ecosystem structures (such as vegetation surveys), purely physical assessment of materials that can be used for ecological restoration, small-model studies carried out in the laboratory or greenhouse with artificial (waste)water or crop studies, or case studies on conventional wastewater treatment and eutrophication that do not offer an ecosystem restoration approach within the paper.
