Trioceros Oweni
Owen's chameleon (''Trioceros oweni''), also commonly known as Owen's three-horned chameleon, is a species of chameleon in the family Chamaeleonidae. The species is native to sub-Saharan Africa. Named after British naval officer and explorer William Fitzwilliam Owen, it was first described in 1831 by the naturalist John Edward Gray, and is the type species of the genus ''Trioceros''. Distribution and habitat Owen's chameleon can be found in much of tropical sub-Saharan Africa, from the Niger Delta in Nigeria in the north, to Angola in the south, and Burundi in the east. It inhabits dense evergreen and semi-deciduous forests at altitudes lower than above sea level, usually living in large trees. The type locality for the species is the island of Bioko in Equatorial Guinea. Description and behavior Like many other chameleons, Owen's chameleon has a prehensile tail and a single claw on each toe. Males have three smooth horns, while females lack horns but have loose skin on thei ...

Musée Cantonal De Zoologie
The Cantonal Museum of Zoology (french: Musée cantonal de zoologie) is a zoology museum in the Palais de Rumine, Lausanne, Switzerland. History The museums history dates from 1779, when the "objects" of natural history in the Académie de Lausanne were indexed by Daniel-Alexandre Chavannes. In 1826, Chavannes vertebrate collection was purchased by L'Etat de Vaud. The museum opened in the Académie de Lausanne in 1833. In 1886, the museum acquired 1,300 specimens bird specimens from Albert Vouga (1829–1896), the author of ''Album Neuchâtelois. Vues historiques et pittoresques'' a book of landscape and natural history photography. Important collections of later date include the ant collection of Auguste Forel and the insect collection of the then Director Jacques Aubert (1916–1995). The museum moved to its present location Palais de Rumine in 1906. Notes and references See also * List of natural history museums This is a list of natural history museums, al ...

Sub-Saharan Africa
Sub-Saharan Africa is, geographically, the area and regions of the continent of Africa that lies south of the Sahara. These include West Africa, East Africa, Central Africa, and Southern Africa. Geopolitically, in addition to the List of sovereign states and dependent territories in Africa, African countries and territories that are situated fully in that specified region, the term may also include polities that only have part of their territory located in that region, per the definition of the United Nations (UN). This is considered a non-standardized geographical region with the number of countries included varying from 46 to 48 depending on the organization describing the region (e.g. UN, WHO, World Bank, etc.). The Regions of the African Union, African Union uses a different regional breakdown, recognizing all 55 member states on the continent - grouping them into 5 distinct and standard regions. The term serves as a grouping counterpart to North Africa, which is instead ...

Agricultural Expansion
Agricultural expansion describes the growth of agricultural land (arable land, pastures, etc.) especially in the 20th and 21st centuries. The agricultural expansion is often explained as a direct consequence of the global increase in food and energy requirements due to continuing population growth (both which in turn have been attributed to agricultural expansion itself), with an estimated expectation of 10 to 11 billion humans on Earth by end of this century. It is foreseen that most of the world's non-agrarian ecosystems (terrestrial and aquatic) will be affected adversely, from habitat loss, land degradation, overexploitation, and other problems. The intensified food (and biofuel) production will in particular affect the tropical regions. Most modern agriculture relies on intensive methods. Further expansion of the predominant farming types that rest on a small number of highly productive crops has led to a significant loss of biodiversity on a global scale already. More ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider pu ...

Least Concern
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

''Chamaeleo'' is a genus of chameleons in the family Chamaeleonidae. Most species of the genus ''Chamaeleo'' are found in sub-Saharan Africa, but a few species are also present in northern Africa, southern Europe, and southern Asia east to India and Sri Lanka. Description Species in the genus ''Chamaeleo'' are slow moving, with independently movable eyes, the ability to change skin colouration, a long tongue, usually a prehensile tail, and special leg adaptations for grasping vegetation. Males are generally larger and more colorful than females. Almost all species have a maximum snout-vent length (SVL) between . Behavior The vast majority of ''Chamaeleo'' species are arboreal and typically found in trees or bushes, but a few species (notably the Namaqua Chameleon) are partially or largely terrestrial. Reproduction The genus ''Chamaeleo'' includes only oviparous species. In captivity With few exceptions, the chameleons most commonly seen in captivity are all members of the ge ...

Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost a ...
