The Crozet Islands are a sub-Antarctic archipelago of small islands in the southern Indian Ocean. They form one of the five administrative districts of the French Southern and Antarctic Lands.
Aaadonta is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Endodontidae. Specimens from this genus are endemic to Palau.
Endodontidae is a taxonomic family of very small air-breathing land snails and slugs, terrestrial pulmonate gastropod mollusks in the superfamily Punctoidea.
Cookeconcha is a genus of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Endodontidae.
Carelia turricula are an extinct species of small, air-breathing, land snails, terrestrial pulmonate gastropod mollusks in the family Amastridae and superfamily Cochlicopoidea.
A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails. Land snail is the common name for terrestrial gastropod mollusks that have shells. However, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and fresh water, and others are relatively amphibious between land and salt water.
Camaenidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea, the typical snails and their allies. This is one of the most diverse families in the clade Stylommatophora.
The Southern Indian Ocean Islands tundra is a tundra ecoregion that includes several subantarctic islands in the southern Indian Ocean.
Slug, or land slug, is a common name for any apparently shell-less terrestrial gastropod mollusc. The word slug is also often used as part of the common name of any gastropod mollusc that has no shell, a very reduced shell, or only a small internal shell, particularly sea slugs and semi-slugs.
A love dart is a sharp, calcareous or chitinous dart which some hermaphroditic land snails and slugs create. Love darts are both formed and stored internally in a dart sac. These darts are made in sexually mature animals only, and are used as part of the sequence of events during courtship, before actual mating takes place. Darts are quite large compared to the size of the animal: in the case of the semi-slug genus Parmarion, the length of a dart can be up to one fifth that of the semi-slug's foot.
Steinera is a genus of lichen-forming fungi in the family Koerberiaceae. It was circumscribed in 1906 by Austrian-Hungarian botanist Alexander Zahlbruckner, who dedicated the genus name to his friend Julius Steiner, an Austrian teacher and lichenologist. The genus was revised by Aino Henssen and Peter Wilfred James in 1982. In 2017, Damien Ernst and Roar Skovlund Poulsen described some new species, and recombined others into the genus based on a study of the genus in the subantarctic islands of Crozet and Kerguelen.
Acaena magellanica, commonly called buzzy burr or greater burnet, is a species of flowering plant whose range includes the southern tip of South America and many subantarctic islands.
Admete specularis is a species of sea snail, a marine gastropod mollusk in the family Cancellariidae, the nutmeg snails.
Galium antarcticum, commonly known as Antarctic bedstraw or subantarctic bedstraw, is a species of flowering plant in the coffee family. It has a largely subantarctic range.
Pseudocyphellaria crocata is a species of lichen in the family Peltigeraceae of the ascomycetes.
Usnea taylorii is a fruticose lichen in the family Parmeliaceae.
Orceolina kerguelensis is a lichen in the family Trapeliaceae. It is the type species of the genus Orceolina.
Megaherbs are a group of herbaceous wildflowers growing in the New Zealand subantarctic islands and on the other subantarctic islands. They are characterised by their great size, with huge leaves and very large and often unusually coloured flowers, which have evolved as an adaptation to the harsh weather conditions on the islands. They suffer from overgrazing due to introduced mammals.
Ducatina is a genus of umbilicate lichen in the family Trapeliaceae. It is monotypic, containing the single species Ducatina umbilicata. Both the genus and species were described as new to science in 2017 by Damien Ertz and Ulrik Søchting. The lichen is widespread and abundant in the remote subantarctic Crozet and Kerguelen Islands in the Indian Ocean, where it grows on the exposed horizontal surfaces of rocks. According to the authors, the thallus morphology is "reminiscent of a weathered metal coin "; the name Ducatina, derived from the word ducatus, refers to this.
Austroplaca hookeri is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It was originally described by Carroll William Dodge in 1965, as Gasparrinia hookeri. The type specimen was originally collected by British botanist and explorer Joseph Dalton Hooker on Cockburn Island; the species is named in his honour. The taxon was transferred to the large genus Caloplaca in 2004, and again to the genus Austroplaca in 2013 as part of a restructuring of the family Teloschistaceae.
