Understanding multi-scale relationships between geodiversity and biodiversity

地质多样性（定义为水文、地貌、土壤和地质在其资源提供潜力方面的多样性）与气候变量（如降水、温度、风）密切相关，它们共同构成所有生物有机体存在的总的非生物生态位。然而，与气候相比，地球多样性变量与生物多样性的关系研究相对不足。生物多样性和地理多样性都是多方面的，高度依赖于规模，与增加面积和时间采样持续时间的非线性关系。此外，在任何特定地区和任何特定时刻，任何单个生物多样性或地质多样性组成部分都可以用其丰富程度和/或丰度来衡量，并有广泛的可用指标。大多数现有的生物多样性-地理多样性文献是在单一的空间和时间尺度上进行的。因此，尺度依赖性在驱动观测到的地球多样性-生物多样性关系变化方面的作用还没有得到很好的理解。该项目旨在利用加那利群岛和厄瓜多尔的案例研究更好地量化规模依赖。结果将有助于更好地确定相关的空间尺度，这些关系可以用来帮助保护管理。这对于生物多样性数据稀少的热带地区尤其重要，使地理多样性和气候变量成为保护规划的潜在重要工具。

Geodiversity (defined as the diversity of hydrology, geomorphology, soil and geology in terms of their resource giving potential) is strongly interlinked with climatic variables (e.g. precipitation, temperature, wind), which together comprise the total abiotic niche in which all biological organisms exist. However, compared with climate, geodiversity variables have been comparatively understudied regarding their relationship with biodiversity. Biodiversity and geodiversity are both multifaceted and highly scale dependent, having non-linear relationships with increasing area and temporal sampling duration. Additionally, within any given area and at any given moment in time, any individual biodiversity or geodiversity component can be measured in terms of their richness and/or abundance, with a broad range of available metrics. Most existing biodiversity-geodiversity literature is conducted at a single spatial and temporal scale. Therefore, the role of scale-dependence in driving variation in observed geodiversity-biodiversity relationships is not well understood. This project aims to better quantify scale-dependence using case studies in the Canary Islands and Ecuador. Results will help better identify relevant spatial scales at which these relationships could be used to aid in conservation management. This is particularly important for tropical regions where biodiversity data is sparse, making geodiversity and climate variables a potentially important tool in conservation planning.
