    Conservation Science W. Aust. 7 (1) : 153–178 (2008) Flora and Vegetation of the banded iron formations of the Yilgarn Craton: the Weld Range ADRIENNE S MARKEY AND STEVEN J DILLON Science Division, Department of Environment and Conservation, Wildlife Research Centre, PO Box 51, Wanneroo WA 6946. Email: [email protected] ABSTRACT A survey of the flora and floristic communities of the Weld Range, in the Murchison region of Western Australia, was undertaken using classification and ordination analysis of quadrat data. A total of 239 taxa (species, subspecies and varieties) and five hybrids of vascular plants were collected and identified from within the survey area. Of these, 229 taxa were native and 10 species were introduced. Eight priority species were located in this survey, six of these being new records for the Weld Range. Although no species endemic to the Weld Range were located in this survey, new populations of three priority listed taxa were identified which represent significant range extensions for these taxa of conservation significance. Eight floristic community types (six types, two of these subdivided into two subtypes each) were identified and described for the Weld Range, with the primary division in the classification separating a dolerite-associated floristic community from those on banded iron formation. Floristic communities occurring on BIF were found to be associated with topographic relief, underlying geology and soil chemistry. There did not appear to be any restricted communities within the landform, but some communities may be geographically restricted to the Weld Range. Because these communities on the Weld Range are so closely associated with topography and substrate, they are vulnerable to impact from mineral exploration and open cast mining.

    Endemism in Recently Diverged Angiosperms Is Associated With Chromosome Set Duplication Sara Villa University of Milan: Universita degli Studi di Milano Matteo Montagna Universita degli Studi di Milano Simon Pierce ( [email protected] ) Università degli Studi di Milano: Universita degli Studi di Milano https://orcid.org/0000-0003-1182- 987X Research Article Keywords: adaptative radiation, apo-endemics, diversity creation, genome doubling, neo-endemism, speciation mechanism Posted Date: June 17th, 2021 DOI: https://doi.org/10.21203/rs.3.rs-550165/v1 License: This work is licensed under a Creative Commons Attribution 4.0 International License. Read Full License Page 1/22 Abstract Chromosome set duplication (polyploidy) drives instantaneous speciation and shifts in ecology for angiosperms, and is frequently observed in neo-endemic species. However, the extent to which chromosome set duplication is associated with endemism throughout the owering plants has not been determined. We hypothesised that across the angiosperms polyploidy is more frequent and more pronounced (higher evident ploidy levels) for recent endemics. Data on chromosome counts, molecular dating and distribution for 4210 species belonging to the major clades of angiosperms were mined from literature-based databases. As all clades include diploid taxa, with polyploids representing a possible ‘upper limit’ to the number of chromosomes over evolutionary time, upper boundary regression was used to investigate the relationship between the number of chromosomes and time since taxon divergence, both across clades and separately for families, with endemic and non-endemic species compared. A signicant negative exponential relationship between the number of chromosomes and taxon age was 2 evident across angiosperm clades (R adj=0.48 with endemics and non-endemics considered together, 2 2 R adj=0.46 for endemics; R adj=0.44 for non-endemics; p ≤0.0001 in all cases), which was three times stronger for endemics (decay constant=0.12, cf.
