Bankoualé Palm
''Livistona carinensis'', commonly known as the Bankoualé palm, is a species of flowering plant in the family Arecaceae. It is one of the fan palms. Its leaves are distinguished by an armed petiole terminating in a rounded, costapalmate fan of numerous leaflets. ''Livistona carinensis'' is found in Djibouti, Somalia, and Yemen, and is threatened by habitat loss Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease ....

Emilio Chiovenda
__NOTOC__ ''Emilio Chiovenda'' (18 May 1871 – 19 February 1941) was an Italian botanist. Chiovenda was born in Rome in 1871 to a family originating from rural Piedmont. He was educated at the Collegio Rosmini in Stresa and Domodossola College before graduating in Natural Sciences from the University of Rome in 1898. He frequently collaborated with Pietro Romualdo Pirotta, under whom he had studied in Rome, including on an unfinished catalogue of flora in Rome and on ''The flora of the colony of Eritrea''. He initially specialised in the flora of the Val d'Ossola valley in Piedmont, where his family had ancestral roots. He collected around 20,000 plant samples, now preserved at the department of Experimental Evolutionary Biology at Bologna University. At the turn of the century he was appointed the first curator of the Colonial Herbarium (''Erbario coloniale'') in Rome, founded to preserve the plant species brought back by scientific expeditions to Italian colonies in East Af ...

Habitat Loss
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and Abundance (ecology), species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the Exploitation of natural resources, use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduced species, introduction of invasive species, ecosystem nutrient depletion, water pollution, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trees Of Africa
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported clear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Yemen
The wildlife of Yemen is substantial and varied. Yemen is a large country in the southern half of the Arabian Peninsula with several geographic regions, each with a diversity of plants and animals adapted to their own particular habitats. As well as high mountains and deserts, there is a coastal plain and long coastline. The country has links with Europe and Asia, and the continent of Africa is close at hand. The flora and fauna have influences from all these regions and the country also serves as a staging post for migratory birds. Geography Yemen is in the southern half of the Arabian Peninsula, bordering the Red Sea, the Gulf of Aden and the Arabian Sea. The country is divided into four geographical regions: the Tihamah or coastal plains to the west, the western highlands, the central highlands, and the Rub' al Khali, or "Empty Quarter", in the east, the largest sand desert in the world. The Tihamah forms an arid flat plain alongside the Red Sea coast. There are many lagoons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Somalia
The wildlife of Somalia includes the flora and fauna of Somalia, which is extremely diverse due to the country's location between the temperate and the tropical zones. Somalia has a long coastline, bordered by the Indian Ocean in the east and Red Sea in the north. The northwestern and central parts of the country are arid, or very dry. The southern and northeastern regions are semi-arid, receiving slightly more rainfall than the central and northwest regions. The coastal region is more humid due to its proximity to the ocean. Somalia is home to over 727 species of birds and boasts over 177 species of mammals. The Nile crocodile, the largest crocodilian found in Africa, is very common in southern Somalia. Somalia is home to a diverse variety of flora and fauna, from acacia trees, to birds, large cats, and reptiles large and small. In some areas, the mountains are covered with shrubs such as pyracantha, jasmine, poinsettia, and a varied assortment of evergreens. Caraway, carcade ...

Flora Of Djibouti
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) wa ...

Livistona
''Livistona'' is a genus of palms, the botanical family Arecaceae, native to southeastern and eastern Asia, Australasia, and the Horn of Africa. They are fan palms, the leaves with an armed petiole terminating in a rounded, costapalmate fan of numerous leaflets. '' L. speciosa'', locally called ''kho'', gives its name to Khao Kho District in Thailand. Taxonomy The genus was established by Robert Brown in his ''Prodromus Florae Novae Hollandiae'' (1810) to accommodate his descriptions of two species collected during an expedition to Australia. The names published by Brown were '' Livistona humilis'' and '' L. inermis'', describing material he had collected in the north of Australia, a partial taxonomic revision in 1963 nominated the first of these as the lectotype. His collaborator Ferdinand Bauer, the botanist and master illustrator, produced artworks to accompany Brown's descriptions, but these were not published until 1838. In 1983 a species of palm from Somalia was for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Dransfield
John Dransfield (born 1945) is former head of palm research at the Royal Botanic Gardens, Kew, United Kingdom. Dransfield has written or contributed to several books on palms, notably both the first and second editions of '' Genera Palmarum''. The first edition was the standard reference for palm evolution and classification and the second edition, expanding on the original, is expected to achieve that same benchmark. He studied at the University of Cambridge, B.A.(1967) biology, M.A. (1970) botany and Ph.D. biology (1970) before working at Kew Gardens. Dransfield was awarded the inaugural David Fairchild Medal for Plant Exploration in 1999, recognising him as the "world authority on the systematics of the palm family (''Arecaceae'')". In 2004, he was awarded the Linnean Medal, an annual award given by the Linnean Society of London. In 2023 Dr. Dransfield was the recipient of the Dent Smith Memorial Award, the highest accolade from the International Palm Society. The genus ...
