Norrard Rocks
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, Isles of Scilly, Bryher and Samson, Isles of Scilly, 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. Nature reserve The islands are largely managed as nature reserves by the Isles of Scilly Wildlife Trust, principally for breeding seabirds and grey seals (''Halichoerus grypus''). The only breeding sites for European Storm–petrel in England are on the Isles of Scilly with eleven colonies and an estimated 1475 occupied sites (i.e. breeding pairs). There are only three small breeding colonies on the Norrard Rocks; Mincarlo, Illiswilgig and Castle Bryher with a total of 3 ...

Bryher, Isles Of Scilly
Bryher ( kw, Breyer "place of hills") is one of the smallest inhabited islands of the Isles of Scilly, with a population of 84 in 2011, spread across . History The name of the island is recorded as ''Brayer'' in 1336 and ''Brear'' in 1500. Geography The island is a procession of prominent hills all joined to one another by low-lying necks and sandy bars. It would only need sea levels to rise by a few metres for the southern part of Bryher to transform itself into a group of five or six separate islands. As all these hills – Gweal, Timmy's, Watch, Heathy and Samson – are too exposed and windswept to be cultivated and Bryher's ninety residents have to make their lives in a relatively narrow zone between hill and shore. The island has a length of , a maximum width of and an area of , including Shipman Head, which rises to at the northern end of the island. Bryher lies to the west of Tresco, and is separated from that island by the Tresco Channel, once the main anchorage fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spiders
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separate t ...

Arachnology
Arachnology is the scientific study of arachnids, which comprise spiders and related invertebrates such as scorpions, pseudoscorpions, and harvestmen. Those who study spiders and other arachnids are arachnologists. More narrowly, the study of spiders alone ( order Araneae) is known as araneology. The word "arachnology" derives from Greek , ''arachnē'', "spider"; and , ''-logia'', "the study of a particular subject". Arachnology as a science Arachnologists are primarily responsible for classifying arachnids and studying aspects of their biology. In the popular imagination, they are sometimes referred to as spider experts. Disciplines within arachnology include naming species and determining their evolutionary relationships to one another (taxonomy and systematics), studying how they interact with other members of their species and/or their environment (behavioural ecology), or how they are distributed in different regions and habitats (faunistics). Other arachnologists perform ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrobates Pelagicus
The European storm petrel, British storm petrel, or just storm petrel (''Hydrobates pelagicus'') is a seabird in the northern storm petrel family, Hydrobatidae. The small, square-tailed bird is entirely black except for a broad, white rump and a white band on the under wings, and it has a fluttering, bat-like flight. The large majority of the population breeds on islands off the coasts of Europe, with the greatest numbers in the Faroe Islands, United Kingdom, Ireland, and Iceland. The Mediterranean population is a separate subspecies, but is inseparable at sea from its Atlantic relatives; its strongholds are Filfla Island (Malta), Sicily, and the Balearic Islands. The storm petrel nests in crevices and burrows, sometimes shared with other seabirds or rabbits, and lays a single white egg, usually on bare soil. The adults share the lengthy incubation and both feed the chick, which is not normally brooded after the first week. This bird is strongly migratory, spending the Norther ...

Gulosus Aristotelis
The European shag or common shag (''Gulosus aristotelis'') is a species of cormorant. It is the only member of the Monotypic taxon, monotypic genus ''Gulosus''. It breeds around the rocky coasts of western and southern Europe, southwest Asia and north Africa, mainly bird migration, wintering in its breeding range except for the northernmost birds. In United Kingdom, Britain this seabird is usually referred to as simply the shag. The scientific genus name derives from the Latin for glutton. The species name ''aristotelis'' commemorates the Greek philosopher Aristotle. Taxonomy The European shag was formerly classified within the genus ''Phalacrocorax'', but a 2014 study found it to be significantly more diverged than the clade containing ''Phalacrocorax'' and ''Urile'', but Basal (phylogenetics), basal to the clade containing ''Nannopterum'' and ''Blue-eyed shag, Leucocarbo'', and thus classified it in its own genus, ''Gulosus''.

Alca Torda
The razorbill, razor-billed auk, or lesser auk (''Alca torda'') is a 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 (''Pinguinis impennis''). Wild populations live in the subarctic waters of the Atlantic Ocean. Razorbills are primarily black with a white underside. The male and female are identical in plumage; however, males are generally larger than females. This agile bird, which is capable of both flight and diving, has a predominantly aquatic lifestyle and only comes to land in order to breed. It is monogamous, choosing one partner for life. Females lay one egg per year. Razorbills nest along coastal cliffs in enclosed or slightly exposed crevices. The parents spend equal amounts of time incubating, and once the chick has hatched, they take turns foraging for their young. In 1918, the razorbill was protected in the United States by the Migratory Bird Treaty Act. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Larus Marinus
The great black-backed gull (''Larus marinus'') is the largest member of the gull family. Described by the Cornell Lab of Ornithology as "the king of the Atlantic waterfront", it is a very aggressive hunter, pirate, and scavenger. It breeds on the European and North American coasts and islands of the North Atlantic and is fairly sedentary, though some move farther south or inland to large lakes or reservoirs. The adult great black-backed gull has a white head, neck and underparts, dark grey wings and back, pink legs and yellow bill. Taxonomy The great black-backed gull was one of the many species originally described by Carl Linnaeus in his 1758 10th edition of ''Systema Naturae'', and it still bears its original name of ''Larus marinus''. The scientific name is from Latin. ''Larus'' appears to have referred to a gull or other large seabird. The specific name ''marinus'' means "marine", or when taken together, "sea gull". This predates Linnean taxonomy, as it had been called ''L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phalacrocorax Carbo
The great cormorant (''Phalacrocorax carbo''), known as the black shag in New Zealand and formerly also known as the great black cormorant across the Northern Hemisphere, the black cormorant in Australia, and the large cormorant in India, is a widespread member of the cormorant family of seabirds. The genus name is Latinised Ancient Greek, from φαλακρός (''phalakros'', "bald") and κόραξ (''korax'', "raven"), and ''carbo'' is Latin for "charcoal". It breeds in much of the Old World, Australia, and the Atlantic coast of North America. Taxonomy and etymology The long white-breasted cormorant ''P. c. lucidus'' found in sub-Saharan Africa, has a white neck and breast. It is often treated as a full species, ''Phalacrocorax lucidus'' (e.g. , ). In addition to the Australasian and African forms, ''Phalacrocorax carbo novaehollandiae'' and ''P. c. lucidus'' mentioned above, other geographically distinct subspecies are recognised, including ''P. c. sinensis'' (western Europ ...

Atriplex
''Atriplex'' () is a plant genus of about 250 species, known by the common names of saltbush and orache (; also spelled orach). It belongs to the subfamily Chenopodioideae of the family Amaranthaceae ''s.l.''. The genus is quite variable and widely distributed. It includes many desert and seashore plants and halophytes, as well as plants of moist environments. The generic name originated in Latin and was applied by Pliny the Elder to the edible oraches. The name saltbush derives from the fact that the plants retain salt in their leaves; they are able to grow in areas affected by soil salination. Description Species of plants in genus ''Atriplex'' are annual or perennial herbs, subshrubs, or shrubs. The plants are often covered with bladderlike hairs, that later collapse and form a silvery, scurfy or mealy surface, rarely with elongate trichomes. The leaves are arranged alternately along the branches, rarely in opposite pairs, either sessile or on a petiole, and are sometim ...

Fratercula Arctica
The Atlantic puffin ('), also known as the common puffin, is a species of seabird in the auk family. It is the only puffin native to the Atlantic Ocean; two related species, the tufted puffin and the horned puffin is found in the northeastern Pacific. The Atlantic puffin breeds in Russia, Iceland, Ireland, Norway, Greenland, Newfoundland and Labrador, Nova Scotia, and the Faroe Islands, and as far south as Maine in the west and France in the east. It is most commonly found in the Westman Islands, Iceland. Although it has a large population and a wide range, the species has declined rapidly, at least in parts of its range, resulting in it being rated as vulnerable by the IUCN. On land, it has the typical upright stance of an auk. At sea, it swims on the surface and feeds on small fish and crabs, which it catches by diving underwater, using its wings for propulsion. This puffin has a black crown and back, pale grey cheek patches, and a white body and underparts. Its broad, boldly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
