Anticipating where are unknown aquatic insects in Europe to improve biodiversity conservation

Abstract

Aim: Understanding biodiversity patterns is crucial for prioritizing future conservation efforts and reducing the current rates of biodiversity loss. However, a large proportion of species remain undescribed (i.e. unknown biodiversity), hindering our ability to conduct this task. This phenomenon, known as the 'Linnean shortfall', is especially relevant in highly diverse, yet endangered, taxonomic groups, such as insects. Here we explore the distributions of recently described freshwater insect species in Europe to (1) infer the potential location of unknown biodiversity hotspots and (2) determine the variables that can anticipate the distribution of unknown biodiversity. Location:The European continent, including western Russia, Cyprus and Turkey.Methods: Georeferenced information of all sites where new aquatic insect species were described across Europe from 2000 to 2020 was compiled. In order to understand the observed spatial patterns in richness of recently described species, spatial

“…Ultimately, certain factors-distribution of the population, distance from the countryside, human footprint, altitude, distance from roads, and distribution of farmland-were used as fixed effects. Wetland units were considered random effects with a Poisson distribution, and only the main effects of the model were considered [36]. To construct a multivariate generalised linear mixed-effects model, all predictor variables were considered potential fixed factors.…”
