Oldenlandia adscensionis was a species of plant in the family Rubiaceae. It was endemic to Ascension Island. It became extinct due to habitat loss; not seen since 1888. [2]
Grapsus grapsus is one of the most common crabs along the western coast of the Americas. It is known as the red rock crab, or, along with other crabs such as Percnon gibbesi, as the Sally Lightfoot crab.
Saint Helena, Ascension Island and Tristan da Cunha, as well the other uninhabited islands nearby, are a haven for wildlife in the middle of the Atlantic Ocean. The islands are or were home to much endemic flora and fauna, especially invertebrates, and many endemic fish species are found in the reef ecosystems off the islands. The islands have been identified by BirdLife International as Important Bird Areas for both their endemic landbirds and breeding seabirds.
Ptisana purpurascens is a large fern belonging to the botanical family Marattiaceae. It has a globular rhizome with stipule-like fleshy outgrowths. The leaves are dark green, twice pinnate and up to 1 metre long. Every pinnule has up to six pairs of leaflets. The petioles are dark-purplish, hence the name 'purpurascens' meaning 'becoming purple'. The sporangia are fused in all Ptisana into a bivalvate synangium.
Oldenlandia is a genus of flowering plants in the family Rubiaceae. It is pantropical in distribution and has about 240 species. The type species for the genus is Oldenlandia corymbosa.
Sporobolus caespitosus is a species of grass in the family Poaceae. It is endemic to Ascension Island, in the South Atlantic Ocean, where it is known only from the weather side of the Green Mountain area, where it occupies an area of less than 0.5 km2. It inhabits the vertical and sloping cinder banks of Green Mountain where very few other species are present, and seems to be adapted to the exposed conditions found at these sites. It is threatened by introduced vegetation and habitat loss.
The resplendent pygmy angelfish is a species of marine ray-finned fish, a marine angelfish, belonging to the family Pomacanthidae. It is endemic to Ascension Island in the South Atlantic Ocean.
Anogramma ascensionis, the Ascension Island parsley fern, is a species of fern in the family Pteridaceae that is endemic to Ascension Island, a volcanic island in the South Atlantic Ocean. It is one of eight putative species in the genus Anogramma. It was thought to have become extinct due to habitat loss, until four plants were found on the island in 2010. Over 60 specimens were then successfully cultivated at Royal Botanic Gardens, Kew and on Ascension Island. It is now classified as Critically Endangered.
Asplenium ascensionis is a species of fern in the family Aspleniaceae. It is endemic to Ascension Island. Its natural habitats are receding due to introduced vegetation. It is threatened by habitat loss.
Oldenlandia aretioides is a species of plant in the family Rubiaceae. It is endemic to Yemen.
Oldenlandia balfourii is a species of plant in the family Rubiaceae. It is endemic to Yemen. Its natural habitat is subtropical or tropical dry forests.
Oldenlandia bicornuta is a species of plant in the family Rubiaceae. It is endemic to Yemen. Its natural habitat is rocky areas.
Oldenlandia ocellata is a species of plant in the family Rubiaceae. It is endemic to Yemen. Its natural habitat is rocky areas. Oldenlandia ocellata is in the "vulnerable" category of the conservation list.
Oldenlandia pulvinata is a species of plant in the family Rubiaceae. It is endemic to Yemen. Its natural habitat is rocky areas.
Pteris adscensionis is a fern species in the subfamily Pteridoideae of the family Pteridaceae. It is endemic to Ascension Island, and there are thought to be fewer than 500 individuals left in the wild. Its natural habitat has been severely reduced due to the large number of species introduced to the island when it was first settled in the 18th century.
The Ascension scrub and grasslands ecoregion covers the dormant volcano, Ascension Island in the Atlantic Ocean. As well as shrubs and grasses wildlife on the island includes a range of unique flora and fauna. In particular the surrounding islets are important havens for many seabirds. However the seabird populations on Ascension Island itself have been severely affected by introduced species, especially cats, which were the subject of an eradication campaign between 2002 and 2006.
Garypus titanius, the giant pseudoscorpion, is the largest species of pseudoscorpion—small, scorpion-looking creatures—in the world. Critically endangered, it is restricted to Boatswain Bird Island, a small rocky island off Ascension Island in the South Atlantic Ocean. Pseudoscorpions are venomous arachnids and are generally tiny—around 3 mm long. The giant pseudoscorpion, though, can grow to five times that size at 11 mm. It lives among seabird colonies, feeding mainly at night on smaller prey such as insects. It belongs to the Garypidae family.
Holocentrus adscensionis is a squirrelfish of the family Holocentridae found in the Atlantic Ocean. Its range extends from North Carolina, USA to Brazil and throughout the Caribbean Sea in the Western Atlantic and from Gabon to Ascension Island in the Eastern Atlantic. A single record was reported in 2016 from the central Mediterranean Sea off Malta.
Grapsus adscensionis is a species of crab found in the eastern Atlantic Ocean.
