Norfolk Hawker
''Aeshna isoceles'' (or ''isosceles'') is a small hawker dragonfly that is found in Europe, mostly around the Mediterranean, and the lowlands of North Africa. Its common name in English is green-eyed hawker. In the United Kingdom it is a localised species, and is called the Norfolk hawker. ''Aeshna isoceles'' is brown, with green eyes, clear wings, and a yellow triangular mark on the second Abdomen#Invertebrates, abdominal segment which gave rise to its scientific name. It used to be in the genus ''Anaciaeschna'' as it different in several ways from the other members of the genus ''Aeshna'' to which it now belongs. Identification ''A. isoceles'' is one of only two brown hawkers found in Europe, the other is ''Aeshna grandis, A. grandis''. Both have a brown thorax and abdomen but ''A. isoceles'' has green eyes and clear wings and a diagnostic yellow triangular mark on the second Abdomen#Invertebrates, abdominal segment. The hindwings have an amber patch at their base. In contrast ...

Otto Friedrich Müller
Otto Friedrich Müller, also known as Otto Friedrich Mueller (2 November 1730 – 26 December 1784) was a Denmark, Danish natural history, naturalist and scientific illustrator. Biography Müller was born in Copenhagen. He was educated for the church, became tutor to a young nobleman, and after several years' travel with him, settled in Copenhagen in 1767, and married a lady of wealth. His first important works, ''Fauna Insectorum Friedrichsdaliana'' (Leipzig, 1764), and ''Flora Friedrichsdaliana'' (Strasbourg, 1767), giving accounts of the insects and flora of the estate of Frederiksdal House, Frederiksdal, near Copenhagen, recommended him to Frederick V of Denmark, by whom he was employed to continue the ''Flora Danica'' a comprehensive atlas of the flora of Denmark. Müller added two volumes to the three published by Georg Christian Oeder since 1761. The study of invertebrates began to occupy his attention almost exclusively, and in 1771 he produced a work in German on “Cer ...

Aeshnidae
Aeshnidae, also called aeshnids, hawkers, or darners, is a family of dragonflies, found nearly worldwide, with more than 50 genera and over 450 species. The family includes some of the largest dragonflies. Description Common worldwide or nearly worldwide genera are '' Aeshna'' and '' Anax''. ''Anax'' includes some of the largest dragonflies, including the North American '' A. walsinghami'', Hawaiian '' A. strenuus'', European '' A. imperator'' and '' A. immaculifrons'', and African '' A. tristis'', but these are all exceeded by another member of the family, the Asian '' Tetracanthagyna plagiata'', which by wingspan and weight is the world's largest dragonfly. There are 41 North American species in 11 genera in this family. Most European species belong to ''Aeshna''. Their American name "darner" stems from the female abdomens looking like a sewing needle, as they cut into plant stem when they lay their eggs through the ovipositor. The dragonflies mate in flight. The eggs are ...

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetics, phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in Taxonomy (biology), taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tre ...

Oviposition
The ovipositor is a tube-like organ used by some animals, especially insects, for the laying of eggs. In insects, an ovipositor consists of a maximum of three pairs of appendages. The details and morphology of the ovipositor vary, but typically its form is adapted to functions such as preparing a place for the egg, transmitting the egg, and then placing it properly. For most insects, the organ is used merely to attach the egg to some surface, but for many parasitic species (primarily in wasps and other Hymenoptera), it is a piercing organ as well. Some ovipositors only retract partly when not in use, and the basal part that sticks out is known as the scape, or more specifically oviscape, the word ''scape'' deriving from the Latin word , meaning "stalk" or "shaft". In insects Grasshoppers use their ovipositors to force a burrow into the earth to receive the eggs. Cicadas pierce the wood of twigs with their ovipositors to insert the eggs. Sawflies slit the tissues of ...

Joint Nature Conservation Committee
The Joint Nature Conservation Committee (JNCC) is the public body that advises the Government of the United Kingdom and devolved administrations on UK-wide and international nature conservation. Originally established under the Environmental Protection Act 1990, JNCC was reconstituted by the Natural Environment and Rural Communities Act 2006. JNCC is led by the Joint Committee, which brings together members from the nature conservation bodies for England, Scotland, Wales and Northern Ireland and independent members appointed by the Secretary of State for the Environment, Food and Rural Affairs under an independent chair. Support is provided to the committee by a company set up and controlled by the Committee solely for that purpose. The company employs around 130 people. They bring together scientific and technical expertise, extensive knowledge of policy at global, European and national levels and skills in working with other organisations. Staff are based in offices in Peterb ...

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are ...

Wildlife And Countryside Act 1981
The Wildlife and Countryside Act 1981 (c. 69) is an act of Parliament in the United Kingdom implemented to comply with European Council Directive 79/409/EEC on the conservation of wild birds. In short, the act gives protection to native species (especially those at threat), controls the release of non-native species, enhances the protection of Sites of Special Scientific Interest and builds upon the rights of way rules in the National Parks and Access to the Countryside Act 1949. The act is split into 4 parts covering 74 sections; it also includes 17 schedules. The legislation has strength; few amendments have been made to it, and it has acted as a foundation for later legislation to build upon. The compulsory five year review of schedules 5 and 8 make it dynamic in terms of the species which it protects. History Wild Birds Protection Act 1902 The Wild Birds Protection Act 1902 ( 2 Edw. 7. c. 6) was an act of Parliament of the Parliament of the United Kingdom, given the ...
