Graphiurus Walterverheyeni
Walter Verheyen's African dormouse (''Graphiurus walterverheyeni'') is a monotypic species of rodent in the family Gliridae. From the Central Congolian lowland forests ecoregion in the central Congo Basin, it has been found in west-central Democratic Republic of the Congo, in the vicinity of the Lukenie River and of Wafania, near the left bank of the Luilaka River. Although not found in immediate association, Lorraine's dormouse (''Graphiurus lorraineus'') and the short-eared African dormouse (''Graphiurus surdus'') are understood to be "broadly sympatric". Most closely resembling Jentink's dormouse (''Graphiurus crassicaudatus''), it differs from this species both in its much smaller size and in its relative proportions. On the IUCN Red List, its conservation status has been assessed as Data Deficient.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mammals Described In 2009
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with ...

Lualaba River
The Lualaba River flows entirely within the eastern Democratic Republic of the Congo. It provides the greatest streamflow to the Congo River, while the source of the Congo is recognized as the Chambeshi. The Lualaba is long. Its headwaters are in the country's far southeastern corner near Musofi and Lubumbashi in Katanga Province, next to the Zambian Copperbelt. Course The source of the Lualaba River is on the Katanga plateau, at an elevation of above sea level. The river flows northward to end near Kisangani, where the name Congo River officially begins. From the Katanga plateau it drops, with waterfalls and rapids marking the descent, to the Manika plateau. As it descends through the upper Upemba Depression (Kamalondo Trough), in .

Lomami River
The Lomami River is a major tributary of the Congo River in the Democratic Republic of the Congo. The river is approximately long. It flows north, west of and parallel to the upper Congo. The Lomami rises in the south of the country, near Kamina and the Congo–Zambezi divide. It flows north through Lubao, , Kombe, Bolaiti, Opala, and Irema before joining the Congo at Isangi. Henry Morton Stanley reached the confluence of the two rivers on 6 Jan. 1877, "the affluent Lumami, which Livingstone calls 'Young's river,' entered the great stream, by a mouth 600 yards wide, between low banks densely covered with trees."Stanley, H.M., 1899, Through the Dark Continent, London: G. Newnes, Vol. One , Vol. Two In October 1889 M. Janssen, Governor-General of the Congo State, explored the Lomani river upstream from Isangi on the ''Ville de Bruxelles''.

Data Deficient
A data deficient (DD) species is one which has been categorized by the International Union for Conservation of Nature (IUCN) as offering insufficient information for a proper assessment of conservation status to be made. This does not necessarily indicate that the species has not been extensively studied; but it does indicate that little or no information is available on the abundance and distribution of the species. The IUCN recommends that care be taken to avoid classing species as "data deficient" when the absence of records may indicate dangerously low abundance: "If the range of a taxon is suspected to be relatively circumscribed, if a considerable period of time has elapsed since the last record of the taxon, threatened status may well be justified""The Categories," in IUCN (1983).

Conservation Status
The conservation status of a group of organisms (for instance, a species) indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status exist and are in use at international, multi-country, national and local levels as well as for consumer use. International systems IUCN Red List of Threatened Species The IUCN Red List of Threatened Species is the best known worldwide conservation status listing and ranking system. Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmentation. Also included are species that have gone ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
