Biodiversity information is plagued with shortfalls, limitations and gaps in the data of all aspects of relevance to understand ecological and evolutionary patterns and processes. These shortfalls that lead to biased biodiversity estimates, preventing a comprehensive understanding of biodiversity patterns, and jeopardizing the effective implementation of data-driven conservation strategies. In our review setting up the basis of the study of shortfalls (see here) we already identified the interactions between shortfalls as one of the key limitations to deal with in order to improve our effectiveness in unveiling biodiversity trends. In this paper we discuss the potential interactions between the shorfalls in the knowledge on species’ taxonomy, geographical distribution and phylogenetic relationships (known as Lineean, Wallacean and Darwinian shortfalls). When new species are described, species diversity patterns based on phylogenies are less affected than those based on richness. In this context, solving the Darwinian shortfall will lead to more robust evaluations of macroecological and biogeographic patterns. However, Latitudinal Taxonomic Gradients provide an interesting framework to explore how uneven knowledge about species taxonomy and geographical distribution link the Linnean, Wallacean, and Darwinian shortfalls and affect the evaluation of diversification patterns.
