Abstract Uluru is the more famous of the two namesake inselbergs found in Uluru Kata-Tjuta National Park (UKTNP). Uluru is roughly 10 km around its base, stands nearly 350 m tall, and can cast a shadow more than a kilometre long during the early morning and late afternoon hours. Additionally, there are many areas near the base of Uluru that receive nearly continuous shade throughout the day, which may also mean that these places could be buffered against extreme temperatures. This study investigated Uluru's influence on the climate at various distances from its base, and simultaneously assessed if the structure of the reptile community was related to the observed climatic variation. We used iButton data loggers to record the temperature and relative humidity at 26 sample locations surrounding Uluru. We used ArcGIS to map the path of Uluru's shadow and to determine when and how long data loggers recorded in and out of Uluru's shading influence. We found that the temperature and relative humidity were strongly influenced by Uluru's shadow, and that reptile assemblages were strongly correlated with the amount of time a sampled site was influenced by Uluru's shadow.

在标志性岛屿的阴影下:乌鲁鲁的阴影影响气候和底部爬行动物的组合结构

摘要 乌鲁鲁是在乌鲁鲁卡塔-丘塔国家公园 (UKTNP) 发现的两个同名岛屿中最著名的一个。乌鲁鲁大约在其基地周围 10 公里处,高近 350 米,在清晨和傍晚时分可以投射出超过一公里长的阴影。此外,乌鲁鲁底部附近的许多区域几乎全天都处于阴凉处,这也可能意味着这些地方可以抵御极端温度。这项研究调查了乌鲁鲁对距其基地不同距离的气候的影响,同时评估了爬行动物群落的结构是否与观测到的气候变化有关。我们使用 iButton 数据记录器记录了乌鲁鲁周围 26 个样本位置的温度和相对湿度。我们使用 ArcGIS 绘制了乌鲁鲁的路径' s 阴影,并确定数据记录器在乌鲁鲁阴影影响内外记录的时间和时间。我们发现温度和相对湿度受到乌鲁鲁阴影的强烈影响,爬行动物组合与采样地点受乌鲁鲁阴影影响的时间量密切相关。
