Abrotanella caespitosa

Abrotanella caespitosa is a member of the daisy family and is an endemic species of the South Island of New Zealand. [1]

Description

Abrotanella caespitosa forms a loose cushion habit with runners that have distant scale leaves. It has narrower leaves compared to its close relatives and lacks a waxy bloom on its leaves. [2]

Distribution and habitat

The species is found in the South Island of New Zealand, with recorded populations in Southland (The Remarkables) and Otago (Rock and Pillar Range). It grows in alpine herbfield habitats. [2]

Taxonomy and evolution

Abrotanella caespitosa is closely related to A. inconspicua , A. nivigena (from Australia), and A. patearoa . These four species form a well-supported clade and have almost identical DNA sequences, suggesting they diverged within the last 500,000 years. Abrotanella caespitosa is part of a radiation of Abrotanella species that occurred during the Pliocene and Pleistocene, associated with mountain building and glaciation episodes. [2]

Moa are an extinct group of flightless birds formerly endemic to New Zealand. During the Late Pleistocene-Holocene, there were nine species. The two largest species, Dinornis robustus and Dinornis novaezelandiae, reached about 3.6 metres (12 ft) in height with neck outstretched, and weighed about 230 kilograms (510 lb) while the smallest, the bush moa, was around the size of a turkey. Estimates of the moa population when Polynesians settled New Zealand circa 1300 vary between 58,000 and approximately 2.5 million.

<span class="mw-page-title-main">New Zealand wren</span> Family of birds

The New Zealand wrens are a family (Acanthisittidae) of tiny passerines endemic to New Zealand. They were represented by seven Holocene species in four or five genera, although only two species in two genera survive today. They are understood to form a distinct lineage within the passerines, but authorities differ on their assignment to the oscines or suboscines. More recent studies suggest that they form a third, most ancient, suborder Acanthisitti and have no living close relatives at all. They are called "wrens" because of similarities in appearance and behaviour to the true wrens (Troglodytidae) but are not members of that family.

<span class="mw-page-title-main">Kōkako</span> Genus of birds

Kōkako are two species of forest bird in the genus Callaeas which are endemic to New Zealand, the endangered North Island kōkako and the presumed extinct South Island kōkako. They are both slate-grey with wattles and have black masks. They belong to a family containing five species of New Zealand wattlebirds, the other three being two species of tieke (saddleback) and the extinct huia. Previously widespread, kōkako populations throughout New Zealand have been decimated by the predations of mammalian invasive species such as possums, stoats, cats and rats, and their range has contracted significantly. In the past this bird was called the New Zealand crow. It is not closely related to the crow, but looks like one from a distance.

<i>Weymouthia</i> (plant) Genus of mosses

Weymouthia is a genus of two species belonging to the feather mosses. Weymouthia occurs in southern South America, New Zealand and south-eastern Australia and Lord Howe Island. It is characterised by (i) its monopodial, often hanging growth form; (ii) slight differences between stem and branch leaves; and (iii) the straight perichaetial leaves. In contrast to other genera in the Lembophyllaceae, secondary stems appear unable to arch back to the substrate and then root and form a new creeping stem.
