Geodiversity inclusiveness in biodiversity assessment

摘要

Biodiversity assessment is constitutive in establishing conservation priorities and outcomes, and geodiversity complements species richness as a surrogate in the absence of species data, improves statistical modelling and can facilitate prediction of species distribution and abundance. Yet, geodiversity is frequently excluded, and biodiversity prioritised in conservation endeavours such as ecosystem-based management. Therefore, combined geodiversity and biodiversity assessment approaches present practical benefits to conservation such as improved collaboration between biologists and geoscientists, efficacious indicators of conservation value, and abatement of biodiversity partialities and wider inclusion of geodiversity in conservation literature. This study scientometrically analysed 240 biodiversity assessment publications to investigate geodiversity inclusiveness, methodological trends, geographic trends, environment-type trends and future directions in biodiversity assessment methods. Results showed these species richness articles frequently included geodiversity-relevant terms such as hydrological, soil, geological and geomorphological components, but the all-encompassing 'geodiversity' term was absent entirely. Geographic trends showed many potential economic, social, cultural and political factors influencing geodiversity inclusiveness in biodiversity assessment. For example, Australia's relatively resource exploitative approach to geology and early involvement in the inception of the geodiversity concept could explain the high frequency of geological-related terms in Australian biodiversity assessments. Methodological trends showed dominance by field-based biodiversity assessments such as trapping methods, followed transects, quadrats, net methods and observations. Given the specific sample size of literature analysed, inferences from this study relate only to biodiversity assessment methods and not biodiversity discourse in its entirety. Subsequent research could investigate specific factors, such as social, economic or political, and their influence on geodiversity inclusiveness in biodiversity assessment methods.
