Class Method Details

.quick_endemism(taxon_name, asserted_distribution_shape_type, asserted_distribution_shape_id) ⇒ Hash

Returns a very simple report summarizing asserted distributions !! only a single shape is used (not its children).

Parameters:

  • taxon_name (TaxonName) —

    required

  • asserted_distribution_shape_type (String) —

    required

  • asserted_distribution_shape_id (Integer) —

    required

Returns:

  • (Hash) —

    a very simple report summarizing asserted distributions !! only a single shape is used (not its children)
