Where in the Dutch East Indies did Sandy Wollaston collect the haplotype on the Setakwa River?
Highland tree frog The Highland treefrog or Wollaston's treefrog ("Litoria wollastoni"), is a species of frog in the Hylidae family, found in West New Guinea. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, rivers, rural gardens, and heavily degraded former forests. It was named in honour of the British naturalist and explorer Sandy Wollaston, who collected the holotype on the Setakwa River, southern Netherlands New Guinea in 1912-1913. The holotype is housed in the Natural History Museum, London, accession number BMNH 1947.2.23.59.
Unare River The Unare River is a river of Venezuela. It drains into the Caribbean Sea. In the 17th century the Dutch had a fort at the mouth of the river. It was constructed to protect their salt collection in the area. The other Dutch fort ever to stand on what is now Venezuelan soil (also in the 17th century) stood on the little uninhabited islet La Tortuga, just west of Isla Margarita. It was built for the same reason as the one in Unare: to protect the salt harvesting activities of the Dutch. The Caribbean islands St. Maarten and Bonaire (still Dutch up to now) would subsequently satisfy the Dutch demand for salt.
