Alca is a genus of charadriiform bird that contains a single extant species, the razorbill (Alca torda). Many fossil species are known, the oldest dating back to the Miocene. The genus appears to have always been restricted to the North Atlantic. [1]
The family Alligatoridae of crocodylians includes alligators, caimans and their extinct relatives.
The great auk is a species of flightless alcid that became extinct in the mid-19th century. It was the only modern species in the genus Pinguinus. It is not closely related to the Southern Hemisphere birds now known as penguins, which were discovered later by Europeans and so named by sailors because of their physical resemblance to the great auk, which were called penguins.
An auk or alcid is a bird of the family Alcidae in the order Charadriiformes. The alcid family includes the murres, guillemots, auklets, puffins, and murrelets. The family contains 25 extant or recently extinct species that are divided into 11 genera.
The razorbill, razor-billed auk, or lesser auk is a North Atlantic colonial seabird and the only extant member of the genus Alca of the family Alcidae, the auks. It is the closest living relative of the extinct great auk.
The Atelidae are one of the five families of New World monkeys now recognised. It was formerly included in the family Cebidae. Atelids are generally larger monkeys; the family includes the howler, spider, woolly, and woolly spider monkeys. They are found throughout the forested regions of Central and South America, from Mexico to northern Argentina.
Sule Stack or Stack Skerry is an extremely remote island or stack in the North Atlantic off the north coast of Scotland. It is formed of Lewisian gneiss.
The Brisons is a twin-peaked islet in the Celtic Sea situated 1 mile (1.6 km) offshore from Cape Cornwall in Cornwall, on the south-western coast of Great Britain.
Lissemys is a genus of softshell turtles in the subfamily Cyclanorbinae of the family Trionychidae. The genus is indigenous to southern Asia.
The Rotoitidae are a very small family of rare, relictual parasitic wasps in the superfamily Chalcidoidea, known primarily from fossils. Only two extant species are known, each in its own genus, one from New Zealand and one from Chile, and little is known about their biology. Females of the Chilean species, Chiloe micropteron, have their wings reduced to tiny bristles. Most fossil species are known from the Late Cretaceous (Santonian) Taimyr amber of Russia and Late Cretaceous (Campanian) Canadian amber, but one species, Baeomorpha liorum is known from the mid Creaceous Burmese amber.
Dr. Laurence Edmondston was a British-born naturalist and doctor who lived in Shetland, Scotland, United Kingdom.
Feliformia is a suborder within the order Carnivora consisting of "cat-like" carnivorans, including cats, hyenas, mongooses, viverrids, and related taxa. Feliformia stands in contrast to the other suborder of Carnivora, Caniformia.
Porcupinefishes or balloonfishes, are any of the various species of the genus Diodon, the type genus of Diodontidae.
Lindsaeaceae is a pantropical family of ferns in the order Polypodiales. It contains six or seven genera with about 220 known species, some of which also extend into the more temperate regions of eastern Asia, New Zealand, and South America.
Trevose Head is a headland on the Atlantic coast of north Cornwall, on the south-western coast of Great Britain. It is situated approximately 5 miles (8.0 km) west of Padstow. The South West Coast Path runs around the whole promontory and is within the Cornwall Area of Outstanding Natural Beauty and the Trevose Head Heritage Coast. In clear weather, visitors to Trevose Head can see virtually the whole length of the north Cornwall coast; to the north, the view extends beyond the Cornwall county boundary to Hartland Point, Devon; to the south, it extends beyond St Ives to the headland at Pendeen Watch.
Pinguinus alfrednewtoni is an extinct species of auk related to the great auk known from fossils that were discovered in the Pliocene Yorktown Formation of North Carolina. Like the great auk, it was a large flightless diving bird that used its wings to propel itself forward underwater. Only a limited amount of material is known, despite the rich diversity of fossil auks recovered from the Yorktown Formation. Due to this, it has been proposed that it was either a more coastal animal or simply not as common in more southern waters. This later suggestion could be supported by the discovery of relatively young P. alfrednewtoni remains, indicating that they may have overwintered in the region. One early hypothesis proposed that it was a direct ancestor to the great auk, but this idea is no longer supported. Instead, it is thought that it filled the same niche as its eastern relative, which eventually expanded into the western Atlantic after the extinction of P. alfrednewtoni.
Gretagrund is a shoal located a few km southeast of Ruhnu island in the Gulf of Riga, Estonia.
The Norrard (Northern) Rocks are a group of small uninhabited granite rocks in the north–western part of the Isles of Scilly, to the west of Bryher and Samson. In 1971 they were designated as a Site of Special Scientific Interest (SSSI) for their breeding seabird colonies and they are permanently closed to landings from boat passengers. The vegetation on the islands is limited by the extreme exposure and only six species of flowering plants have been recorded.
Nogodinidae is a family of planthoppers. They have membranous wings with delicate venation and can be confused with members of other Fulgoroid families such as the Issidae and Tropiduchidae. Some authors treat it as a subfamily of the Issidae. Some of their key features are a frons ("face") that is longer than wide and a reticulate wing venation. They are less than 2 cm long. The antenna arises well below the eye, has the base clubbed and flagellum unsegmented. The lateral ocelli are outside the margins of the face. The face has carinae on the edge. On the hind leg, the second tarsal segment has an apical spine arising from it. The tibia of the hind leg also has spines towards the tip. An important family character is found in the shape of the male genital structure, a style that is longer than broad. Most members of this family are forest species.
Stø is a fishing village located on the northern tip of the island of Langøya, along the Gavlfjorden in the Vesterålen archipelago. It is part of the municipality of Øksnes in Nordland county, Norway. In 2001, there were about 175 residents. This village was the administrative centre of the old municipality of Langenes which existed from 1919 until 1964.
Lågskär is a small island within the Åland archipelago of Finland. It belongs to the municipality of Lemland. It is situated about 24 kilometres (15 mi) south of Mariehamn in the Baltic's Sea of Åland. The main island of Lågskär measures 61 hectares in area. Rock stacks, sea cliffs and rocky shores are found along the coastline of the island. As a breeding ground for waterfowl, Lågskär has the status of an Important Bird Area (IBA) and is frequented by ornithologists who use the Lågskär Lighthouse buildings during their stay. In the past, several vessels have sunk off the coast.
