Species occurence dataset of the pantropical Caesalpinia Group

Latest version published by Université de Montréal Biodiversity Centre on Oct 23, 2019 Université de Montréal Biodiversity Centre

A total of 17,260 species occurrence data spanning more than 200 species and infraspecific taxa and all 26 genera, were assembled to generate the Caesalpinia Group distribution maps. Vouchered occurrence records (Basis of Record: Preserved Specimen) were downloaded from the Global Biodiversity Information Facility (GBIF; (June 2017), SEINet (http://swbiodiversity.org/seinet/) and DryFlor (http://www.dryflor.info/). To improve accuracy, the distribution of each species was mapped and checked against monographs or expert knowledge, and obvious outliers removed. Occurrence points located in the sea, in botanical gardens, on the centroid of a country, or with coordinates only at the level of degrees, were removed. Data handling was performed in R (R Core Team, 2018). This dataset was generated as part of the following publication: Gagnon, E., Ringelberg, J., Lewis, G.P., Bruneau, A. & Hughes, C.E. (2018; accepted, pending revisions) Global Succulent Biome phylogenetic conservatism across the pantropical Caesalpinia Group (Leguminosae). New Phytologist.

Data Records

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 17,207 records.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Project Data

The extent to which phylogenetic biome conservatism versus biome shifting determine global patterns of biodiversity remains poorly understood. To address this question, we investigate the biogeography and trajectories of biome and growth form evolution across the Caesalpinia Group (Leguminosae), a clade of 225 species of trees, shrubs and lianas distributed across the Rainforest, Succulent, Temperate and Savanna Biomes. We focus especially on the little-known Succulent Biome, an assemblage of succulent-rich, grass-poor, seasonally dry tropical vegetation distributed disjunctly across the Neotropics, Africa, Arabia and Madagascar. We reconstruct a time-calibrated phylogeny, assemble species occurrence data, and assign species to areas, biomes and growth forms. These data are used to estimate the frequency of trans-continental disjunctions, biome shifts and evolutionary transitions between growth forms and test for phylogenetic biome conservatism and correlated evolution of growth forms and biome shifts. We uncover a pattern of strong phylogenetic Succulent Biome conservatism. We show that trans-continental disjunctions confined within the Succulent Biome are frequent and that biome shifts to the Savanna, Rainforest and Temperate Biomes are infrequent and closely associated with shifts in plant growth forms. Our results suggest that the Succulent Biome comprises a tightly constrained evolutionary arena spanning large geographical disjunctions across the tropics.

Sampling Methods

Vouchered (Basis of Record: Preserved Specimen) occurrence records were downloaded from the Global Biodiversity Information Facility (GBIF; June 2017), SEINet (http://swbiodiversity.org/seinet/) and DryFlor (http://www.dryflor.info/). A total of 17,260 occurrence records were kept as part of the final dataset.

Study Extent Pantropical (all distribution of 225 species + infraspecific taxa within the Caesalpinia Group).
Quality Control Occurrence points located in the sea, in botanical gardens, on the centroid of a country, or with coordinates only at the level of degrees, were removed. To improve accuracy, the distribution of each species was mapped and checked against monographs or expert knowledge, and obvious outliers removed.

Method step description:

  1. Data handling was performed in R (R Core Team, 2018), and scripts are available upon request from the authors of the dataset.
