George Allman (natural Historian)
George James Allman FRS FRSE (181224 November 1898) was an Irish ecologist, botanist and zoologist who served as Emeritus Professor of Natural History at Edinburgh University in Scotland. Life Allman was born in Cork, Ireland, the son of James C. Allman of Bandon, and received his early education at the Royal Academical Institution, Belfast. For some time he studied for the Irish Bar, but ultimately gave up law in favour of natural science. In 1843, he graduated in medicine at Trinity College, Dublin, and in the following year was appointed professor of botany in that university, succeeding the botanist William Allman (1776–1846), who was the father of George Johnston Allman (distant relations of George). This position he held for about twelve years until he moved to Edinburgh as Regius Professor of natural history. There he remained until 1870, when considerations of health induced him to resign his professorship and retire to Dorset, where he devoted himself to his favo ...

William Allman
William Allman, M.D. (1776–1846) was Professor of Botany at Dublin."Alumni Dublinenses : a register of the students, graduates, professors and provosts of Trinity College in the University of Dublin (1593–1860George Dames Burtchaell/Thomas Ulick Sadleir p12: Dublin, Alex Thom and Co, 1935 He was born at Kingston, Jamaica, on 7 February 1776, but his parents removed to Ireland before he was four years of age, his mother being a native of Waterford. He was educated in that town, and Trinity College Dublin, where he was elected a Scholar, and graduated B.A. in 1796, M.A. in 1801, and M.D. in 1804. He practised medicine in Clonmel until 1809 when he was elected Professor of Botany at Trinity College Dublin. Soon after this event he became acquainted with Robert Brown, the botanist, with whom his friendship was lifelong. In consequence of this intimacy, Dr. Allman arranged lectures in 1812 on the natural system, he being the first professor in the British isles to do so. He h ...

Royal Irish Academy
The Royal Irish Academy (RIA; ga, Acadamh Ríoga na hÉireann), based in Dublin, is an academic body that promotes study in the sciences, humanities and social sciences. It is Ireland's premier List of Irish learned societies, learned society and one its leading List of Irish cultural institutions, cultural institutions. The Academy was established in 1785 and granted a royal charter in 1786. the RIA has around 600 members, regular members being Irish residents elected in recognition of their academic achievements, and Honorary Members similarly qualified but based abroad; a small number of members are elected in recognition of non-academic contributions to society. Until the late 19th century the Royal Irish Academy was the owner of the main national collection of Irish antiquities. It presented its collection of archaeological artefacts and similar items, which included such famous pieces as the Tara Brooch, the Cross of Cong and the Ardagh Chalice to what is now the Na ...

Cunningham Medal
The Cunningham Medal is the premier award of the Royal Irish Academy. It is awarded every three years in recognition of "outstanding contributions to scholarship and the objectives of the Academy". History It was which was established in 1796 at the bequest of barrister Timothy Cunningham of Gray's Inn. After a period of uncertainty and experimentation regarding the terms and conditions of the award, it was agreed in 1848 that the medals would be open to the authors of works or essays in the areas of Science, Polite Literature and Antiquities, published in Ireland or about Irish subjects. After 1885, the academy stopped giving the award, but it was revived in 1989 for the bicentennial of Cunningham's gift. Recipients The following persons have been awarded the Cunningham Medal: *1796: Thomas Wallace *1800: Theophilus Swift (writing, poetry) *1805: William Preston (poetry) *1818: John Brinkley (astronomy) *1827: John D'Alton (history) *1830: George Petrie (history) *1833: G ...

Royal Society
The Royal Society, formally The Royal Society of London for Improving Natural Knowledge, is a learned society and the United Kingdom's national academy of sciences. The society fulfils a number of roles: promoting science and its benefits, recognising excellence in science, supporting outstanding science, providing scientific advice for policy, education and public engagement and fostering international and global co-operation. Founded on 28 November 1660, it was granted a royal charter by King Charles II as The Royal Society and is the oldest continuously existing scientific academy in the world. The society is governed by its Council, which is chaired by the Society's President, according to a set of statutes and standing orders. The members of Council and the President are elected from and by its Fellows, the basic members of the society, who are themselves elected by existing Fellows. , there are about 1,700 fellows, allowed to use the postnominal title FRS (Fellow of the ...

Irish Naturalist
''The Irish Naturalist'' was a scientific journal that was published in Dublin, Ireland, from April 1892 until December 1924. History The journal owed its establishment to the efforts of several leading Dublin naturalists, notably George H. Carpenter and R. M. Barrington. The first editors were Carpenter and Robert Lloyd Praeger, of the National Library of Ireland. The journal was supported by a number of societies, including the Royal Zoological Society of Ireland, the Dublin Microscopical Club, the Belfast Naturalists' Field Club, and the Dublin Naturalists' Field Club. ''The Irish Naturalist'' was published for 33 years and contained in total over 3000 pages. The journal ceased publication in December 1924. It had been having some financial problems, but the final blow came when Carpenter took up his appointment to the keepership of the Manchester Museum in 1923. The journal was succeeded in 1925 by the '' Irish Naturalists' Journal''. Contributors Among notable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coelenterata
Coelenterata is a term encompassing the animal phyla Cnidaria (coral animals, true jellies, sea anemones, sea pens, and their relatives) and Ctenophora (comb jellies). The name comes , referring to the hollow body cavity common to these two phyla. They have very simple tissue organization, with only two layers of cells (ectoderm and endoderm), and radial symmetry. Some examples are corals, which are typically colonial, and hydrae, jellyfish, and sea anemones, which are solitary. Coelenterata lack a specialized circulatory system relying instead on diffusion across the tissue layers. Characteristics All coelenterates are aquatic, mostly marine, animals. The body form is radially symmetrical, diploblastic and does not have a coelom. The body has a single opening, the , surrounded by sensory tentacles equipped with either nematocysts or colloblasts to capture mostly planktonic prey. These tentacles are surrounded by a spacious cavity called the gastrovascular cavity, or coelen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germ Layer
A germ layer is a primary layer of cells that forms during embryonic development. The three germ layers in vertebrates are particularly pronounced; however, all eumetazoans (animals that are sister taxa to the sponges) produce two or three primary germ layers. Some animals, like cnidarians, produce two germ layers (the ectoderm and endoderm) making them diploblastic. Other animals such as bilaterians produce a third layer (the mesoderm) between these two layers, making them triploblastic. Germ layers eventually give rise to all of an animal’s tissues and organs through the process of organogenesis. History Caspar Friedrich Wolff observed organization of the early embryo in leaf-like layers. In 1817, Heinz Christian Pander discovered three primordial germ layers while studying chick embryos. Between 1850 and 1855, Robert Remak had further refined the germ cell layer (''Keimblatt'') concept, stating that the external, internal and middle layers form respectively the e ...

Ectoderm
The ectoderm is one of the three primary germ layers formed in early embryonic development. It is the outermost layer, and is superficial to the mesoderm (the middle layer) and endoderm (the innermost layer). It emerges and originates from the outer layer of germ cells. The word ectoderm comes from the Greek ''ektos'' meaning "outside", and ''derma'' meaning "skin".Gilbert, Scott F. Developmental Biology. 9th ed. Sunderland, MA: Sinauer Associates, 2010: 333-370. Print. Generally speaking, the ectoderm differentiates to form epithelial and neural tissues (spinal cord, peripheral nerves and brain). This includes the skin, linings of the mouth, anus, nostrils, sweat glands, hair and nails, and tooth enamel. Other types of epithelium are derived from the endoderm. In vertebrate embryos, the ectoderm can be divided into two parts: the dorsal surface ectoderm also known as the external ectoderm, and the neural plate, which invaginates to form the neural tube and neural crest.

Endoderm
Endoderm is the innermost of the three primary germ layers in the very early embryo. The other two layers are the ectoderm (outside layer) and mesoderm (middle layer). Cells migrating inward along the archenteron form the inner layer of the gastrula, which develops into the endoderm. The endoderm consists at first of flattened cells, which subsequently become columnar. It forms the epithelial lining of multiple systems. In plant biology, endoderm corresponds to the innermost part of the cortex ( bark) in young shoots and young roots often consisting of a single cell layer. As the plant becomes older, more endoderm will lignify. Production The following chart shows the tissues produced by the endoderm. The embryonic endoderm develops into the interior linings of two tubes in the body, the digestive and respiratory tube. Liver and pancreas cells are believed to derive from a common precursor. In humans, the endoderm can differentiate into distinguishable organs after 5 week ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ray Society
The Ray Society is a scientific text publication society that publishes works devoted principally to British flora and fauna. As of 2019, it had published 181 volumes. Its publications are predominantly academic works of interest to naturalists, zoologists, botanists and collectors. The society was founded in 1844, largely on the initiative of George Johnston and named after the naturalist John Ray (1627–1705). It is based at the Natural History Museum, London, and is a registered charity under English law. Publications The Ray Society's publications are concerned with natural history, and have special but not exclusive reference to British flora and fauna. They include original monographs on particular groups and topics, facsimiles of historically important volumes and translations of existing works. During Charles Darwin's lifetime, the Ray Society published not only Darwin's two volumes on living barnacles (1851 and 1854) but also the work of many of the foremost British nat ...

Hydrozoa
Hydrozoa (hydrozoans; ) are a taxonomic class of individually very small, predatory animals, some solitary and some colonial, most of which inhabit saline water. The colonies of the colonial species can be large, and in some cases the specialized individual animals cannot survive outside the colony. A few genera within this class live in freshwater habitats. Hydrozoans are related to jellyfish and corals and belong to the phylum Cnidaria. Some examples of hydrozoans are the freshwater jelly (''Craspedacusta sowerbyi''), freshwater polyps ('' Hydra''), ''Obelia'', Portuguese man o' war (''Physalia physalis''), chondrophores (Porpitidae), "air fern" (''Sertularia argentea''), and pink-hearted hydroids (''Tubularia''). Anatomy Most hydrozoan species include both a polyp (zoology), polypoid and a medusa (biology), medusoid stage in their lifecycles, although a number of them have only one or the other. For example, ''Hydra'' has no medusoid stage, while ''Liriope tetraphylla, Lir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
