Class Method Summary collapse

Class Method Details

.quick_endemism(taxon_name, shape_type, shape_id) ⇒ Hash

Returns name => not endemic boolean a very simple report summarizing asserted distributions !! only a single shape is used (i.e. a taxon endemic to a child

of the given shape will not match).

Parameters:

  • taxon_name (TaxonName) —

    required

  • shape_type (String) —

    required

  • shape_id (Integer) —

    required

Returns:

  • (Hash) —

    name => not endemic boolean a very simple report summarizing asserted distributions !! only a single shape is used (i.e. a taxon endemic to a child

    of the given shape will not match)
