Rare species can be mapped more accurately with new statistical approach
Information on Earth's biodiversity is increasingly collected using DNA-, image- and audio-based sampling. At the same time, new statistical analysis methods are being developed to make more out of the collected data, providing detailed information on Earth's biodiversity and its status. Now, an international research group has developed a new statistical approach for jointly modeling the distributions of up to millions of species. The new approach improves predictions especially on rare species that have remained difficult to model with earlier approaches. Earth is home to several millions of species, and only a fraction of nature's diversity is currently known. One reason for this is that many rare species are difficult to detect, which means that we may not even know about their existence, or at least that there is a lack of information available to evaluate their endangerment status. This can lead to inaccurate and incomplete assessments of their abundance and the rea...
