The Screw Pine is a geographically widespread and exceptionally morphologically variable species (or maybe a species complex). In the Polynesian region this plant is found almost everywhere, except for climatically inappropriate areas like New Zealand or Rapa Nui.

The Screw Pine was once one of the most important plants for the Polynesians, and Screw Pine saplings, together with saplings of Breadfruit Trees, Coconut Palms, Taro and several others, were transported by the Polynesian settlers on their boats during inter-island migration – to be planted out at their new island homes.

The Polynesians, over time, reared numerous cultivars, among them such whose leaves are lacking spines on their margins, and which therefore are very well-suited for weaving.

The exceptional variability of the wild and cultivated forms lead to the description of countless species, subspecies and varieties. So, Harold St. John alone described in his “Revision of the Genus Pandanus” various female plants as distinct species – in many cases from geographically very localized populations. In a biological sense, all of these ‘species’ are part of the same population, and furthermore, it is impossible to designate male plants to such ‘species’.

Some of the morphologically distinct forms that are seemingly restricted to the higher elevations of larger islands, like Pandanus papenooensis H. St. John on Tahiti or Pandanus temehaniensis J. W. Moore on Ra’iatea, are often still referred to as distinct species.

(I personally, however, see all of these forms as Pandanus tectorius.)

Nevertheless, the genus is in urgent need of a proper revision!

~~~

As already mentioned, in virtually all parts of Polynesia the leaves were and are used for weaving, among other things, for elaborate mats, especially in Tonga, or boat sails (in former times on the Hawai’i Islands), right up to roofs and walls of houses (!). The stilt roots were used, for example, on the Cook Islands, for house building (as abutment walls) too.

The fruits are fruit heads comprising an aggregate of many tightly bunched phalanges or drupes that are edible. In some cultivars, these drupes reach the size of an apple. They are eaten especially in parts of Kiribati, Tokelau, and in Tuvalu.

Ischnura jeanyvesmeyeri Englund & Polhemus

Raivavae Forktail (Ischnura jeanyvesmeyeri)

This species was described in the year 2010.

The species reaches a body size of about 4,2 cm, the wingspan is about 4,4 cm.

Despite the fact that virtually all streams on the island of Raivavae are diverted for agricultural uses to some extent, the Raivavae Forktail is still quite common at a wide range of elevations, it is, however, restricted to heavily vegetated areas along shaded stream reaches and avoids the adjoining large lowland taro fields, which again are preferred by the widespread Aurora Bluetail (Ischnura aurora Brauer).

The streams on the island of Raivavae are almost always small brooks, less than 1 m wide and only 5 to 15 cm deep, these streams are often lined with thickets of anue (Dicranopteris linearis (Burm. f.) Underw.), with a bed substrate consisting mainly of bare rock, but with abundant root mats and mats of aquatic algae.

The females are known to oviposit in such algae- or root mats.

This ‘species’ in fact isn’t a species in the common sense, it is most probably not monophyletic, that means the species’ name covers more than one species.

The Polynesian populations extend from Fiji into central Polynesia (Cook Islands, Society Islands) and east Polynesia (Tuamotu Archipelago). The western populations may be native, the central and eastern, however, were most probably imported by early Polynesian settlers.

There is still a lot to discover …. [1][2][3][4][5]

Awaous ocellaris Broussonet

Eyespot Goby (Awaous ocellaris)

The Eyespot Goby is an about 13 cm long freshwater goby that is indigenous to many mangrove areas, estuaries, and rivers from India to Polynesia.

The fish feed on green algae, small crabs, freshwater shrimps, and other invertebrates.

Like all Polynesian freshwater gobies, also the Eyspot Goby has an amphidromous life cycle, which means, that the spawning takes place in the freshwater, but the embryos are washed out into the ocean, where they remain for a planktonic phase before they return into freshwater to grow and to start the life cycle again.

The Samoan name of the species is mano’o ia pala.
