Waldock et al. 2020 Ecography: Insect occurrence in agricultural land-uses depends on realized niche and geographic range properties
<p>This file contains the site-level data from the PREDICTS database, code to develop environmental niche estimates for species from GBIF occurrences, and all statistical analysis investigating the role of species environmental niches in determining occupancy in agro-ecosystems used in the publication: Waldock et al. 2020 Ecography.</p>
Data from: Geographic ranges of genera and their constituent species: structure, evolutionary dynamics, and extinction resistance
We explore the relationships among the geographic ranges of genera, the ranges and positions of their constituent species, and the number of species they contain, considering variation among coeval genera and changes within genera over time. Measuring range size as the maximal distance, or extent, between occurrences within a taxon, we find that the range of the most widespread species is a good predictor of the range of the genus, and that the number of species is a better predictor still. This analysis is complicated by a forced correlation: the range of a genus must be at least as large as that of each of its constituent species. We therefore focus on a second measure of range, the mean squared distance, or dispersion, of occurrences from the geographic centroid, which, by analogy to the analysis of variance, allows the total dispersion of a genus to be compared to the mean within-species dispersion and the dispersion among species centroids. We find that among-species dispersion is the principal determinant of genus dispersion. Within-species dispersion also plays a major role. The role of species richness is relatively small. Our results are not artifacts of temporal variation in the geographic breadth of sampled data. The relationship between changes in genus dispersion and changes in within- and among-species dispersion shows a symmetry, being similar in cases when the genus range is expanding and when it is contracting. We also show that genera with greater dispersion have greater extinction resistance, but that within- and among-species dispersion are not demonstrable predictors of survival once the dispersion of the genus is accounted for. Thus it is the range of the genus, rather than how it is attained, that is most relevant to its fate. Species richness is also a clear predictor of survival, beyond its effects on geographic range.
Coupling of geographic range and provincialism in Cambrian marine invertebrates
<p>The file contains original download of occurrences from PBDB (pbdb_occ_download.csv) and the dataset ((Cambrian_pbdb_2021-09-03.csv)) used for the study, the temperoal binning of which is based on biostratigraphic correlation in supplementary file S1.

Figure 1. Map of Indo-West Pacific collection localities where specimens of the digenean family Gorgocephalidae were obtained for the present study. Adult specimens were obtained at all localities except for Kioloa, NSW, Australia. At this locality, intramolluscan specimens had been obtained from littorinid gastropods for the study of Huston et al. (2016); genomic DNA from this previous study was used for the generation of additional COI mtDNA gene sequences in the present work.
