Effectively and accurately mapping global biodiversity patterns for different regions and taxa

Abstract: Understanding patterns of biodiversity is crucial for developing appropriate conservation and management plans. The IUCN RedList is looked upon as a source of globally-consistent assessment of species extinction risk, including range maps as part of the extinction risk assessment. Species ranges are a central criterion in determining extinction vulnerability, and consequently apportioning conservation and research efforts. Thus, the accuracy of these maps is crucial to the effective conservation of global biod… Show more

“…Unfortunately, the resources presently available are not yet fit for the purpose of understanding and protecting global biodiversity, although many researchers attempt to do this. In common practice, current views of the natural world are limited either to ‘expert opinion' IUCN maps, where inherent knowledge gaps have huge consequences of data use, including persistent administrative‐area biases (Hughes et al 2021), or a coverage completeness for < 6.74% of the planet, based on terrestrial, temperate lowlands near roads and cities in developed countries and their coastal regions. Neither data set is currently sufficient for truly global analyses, and efforts must be made to better integrate these data, such that they may help alleviate the weaknesses and biases of each other.…”

“…The inclusion of these measures enables prioritisation of cave ecosystems with rare and higher functional diversity attributes 67,68 complimenting the metrics based on geopolitical endemism and conservation status from IUCN [68][69][70] which are commonly used within prioritisation schemes. While the expert-based Redlist developed by the IUCN is the most comprehensive basis for conservation and species protection, it is not free from biases [71][72][73] , especially for bats, in which a large proportion of species are either taxonomically and spatially under-sampled or disproportionately studied particularly in most megadiverse and developing countries 74 . Overall, our observed patterns are consistent with previous global studies comparing the value of broad-and fine-scale analyses in identifying priorities.…”

“…Understanding the spatial distribution of biodiversity and its linkage across ecosystem types is essential, especially in an era of increasing human modifications of natural landscapes 1,2 . It is well-established that species and ecosystem functional diversity are unevenly distributed across landscapes, with pronounced diversity hot and cold spots 3,4 . Extensive work has also demonstrated how ecosystems more diverse in species are more productive and stable [5][6][7] .…”
