Data from: Near-global freshwater-specific environmental variables for biodiversity analyses in 1km resolution

The lack of freshwater-specific environmental information at sufficiently fine spatial grain hampers broad-scale analyses in aquatic biology, biogeography, conservation, and ecology. Here we present a near-global, spatially continuous, and freshwater-specific set of environmental variables in a standardized 1 km grid. We delineate the sub-catchment for each grid cell along the HydroSHEDS river network and summarize the upstream climate, topography, land cover, surface geology and soil to each grid cell using various metrics (average, minimum, maximum, range, sum, inverse distance-weighted average and sum). All variables were subsequently averaged across single lakes and reservoirs of the Global lakes and Wetlands Database that are connected to the river network. Monthly climate variables were summarized into 19 long-term climatic variables following the 'bioclim' framework. This new set of variables provides a basis for spatial ecological and biodiversity analyses in freshwater ecosystems at near global extent, yet fine spatial grain. To facilitate the generation of freshwater variables for custom study areas and spatial grains, we provide the 'r.stream.watersheds' and 'r.stream.variables' add-ons for the GRASS GIS software.

Data from: Estimating global biodiversity: the role of cryptic insect species

<p>How many species are there on Earth and to what groups do these species belong? These fundamental questions span systematics, ecology, and evolutionary biology. Yet, recent estimates of overall global biodiversity have ranged wildly, from the low millions to the trillions. Insects are a pivotal group for these estimates. Insects make up roughly half of currently described extant species (across all groups), with ~1 million described species. Insect diversity is also crucial because many other taxa have species that may be unique to each insect host species, including bacteria, apicomplexan protists, microsporidian fungi, nematodes, and mites. Several projections of total insect diversity (described and undescribed) have converged on ~6 million species. However, these projections have not incorporated the morphologically cryptic species revealed by molecular data. Here, we estimate the extent of cryptic insect diversity. We perform a systematic review of studies that used explicit species-delimitation methods with multi-locus data. We estimate that each morphology-based insect species contains (on average) 3.1 cryptic species. We then use these estimates to project the overall number of species on Earth and their distribution among major groups. Our estimates suggest that overall global biodiversity may range from 563 million to 2.2 billion species.</p>

Fig. 2 Bayesian total-evidence dated phylogeny of Cycadales. This chronogram is the resulting consensus tree from the MrBayes analyses performed with the fossilized-birth-death model and an uncorrelated relaxed molecular clock. The tree includes 321 extant species and 60 extinct species with median divergence times along with 95% Highest Posterior Density (blue bars) for each node.

Fig. 4 in Research Reconciling fossils with phylogenies reveals the origin and macroevolutionary processes explaining the global cycad biodiversity

Fig. 4 Historical biogeography of cycads. Estimates of ancestral areas were performed with a time-stratified model in Dispersal–Extinction–Cladogenesis (DEC) with fossils included (a) and with fossils excluded (b). The extant genera have been collapsed to focus on deep-time biogeography (for details within each genus, see Supporting Information Fig. S6 when fossils are included and Fig. S7 when fossils are excluded). The bottom-right corner legend indicates colored areas used in this study corresponding to colored squares for each node, representing inferred ancestral area(s) with the DEC model, and colored circles for fossil species representing known distributions (except for extant genera with one or two species only). The red-highlighted shades show the cycad expansion into Gondwana during the Jurassic and Cretaceous. The bottom-left corner map represents the global paleogeography in the Jurassic (180 million years ago (Ma)). Paleomap used with permission © 2020 Colorado Plateau Geosystems Inc. Arrows indicate fossil species illustrated. Pictures from Mario Coiro. C, Carboniferous; N, Neogene; Perm, Permian; Pg, Paleogene.
