Assessing the Geographical Structure of Species Richness Data with Interactive Graphics
(The Eurographics Association, 2021) Morgades, Pauline; Slingsby, Aidan; Moat, Justin; Dutta, Soumya and Feige, Kathrin and Rink, Karsten and Zeckzer, Dirk
Understanding species richness is an important aspect of biodiversity studies and conservation planning, but varying collection effort often results in insufficient data to have a complete picture of species richness. Species accumulation curves can help assess collection completeness of species richness data, but these are usually considered by discrete area and do not consider the geographical structure of collection. We consider how these can be adapted to assess the geographical structure of species richness over geographical space.We design and implement two interactive visualisation approaches to help assess how species richness data varies over continuous geographical space. We propose these designs, critique them, report on the reactions of four ecologists and provide perspectives on their use for assessing geographical incompleteness in species richness.
