Callulina Laphami
''Callulina laphami'' is a species of frogs in the family Brevicipitidae. It was discovered in 2010 during a survey of rainforests in the northern part of the Eastern Arc Mountains of Tanzania. It is present at a single location in the Kindoroko and Minja Forest Reserves in the Pare Mountains. The forest area in which this frog lives is a remnant patch of a larger forest with trees in the surrounding area being felled for agricultural development, and the International Union for Conservation of Nature has rated the frog's conservation status as " critically endangered". Description ''Callulina laphami'' is a robust species of brevicipitid frog with a plump body and distinctive ridges of glands on its arms and legs. It has no tympani and no enlarged pads on the tips of its fingers and toes. Males have a snout-to-vent length of while females vary from . This frog's dorsal surface is dark brown, its flanks are tan and its ventral surface yellowish-cream. In most individuals there i ...

IUCN Red List Of Threatened Species
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 International Union for Conservation of Nature, 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.

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] |
Amphibians Of Tanzania
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decline ...

Endemic Fauna Of Tanzania
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Callulina
''Callulina'' (commonly known as the warty frogs) is a small genus of frogs in the family Brevicipitidae with nine members in Tanzania and Kenya. Originally ''Callulina'' was thought to be monotypic and widely distributed through Eastern Arc Mountains in Tanzania and in southern Kenya. However, within the last decade eight new species has been identified, the majority of which are considered critically endangered by the International Union for Conservation of Nature (IUCN). Species Amphibian Species of the World ''Amphibian Species of the World 6.1: An Online Reference'' (ASW) is a herpetology database.

Direct Development
Marine larval ecology is the study of the factors influencing dispersing larvae, which many marine invertebrates and fishes have. Marine animals with a larva typically release many larvae into the water column, where the larvae develop before metamorphosing into adults. Marine larvae can disperse over long distances, although determining the actual distance is challenging, because of their size and the lack of a good tracking method. Knowing dispersal distances is important for managing fisheries, effectively designing marine reserves, and controlling invasive species. Theories on the evolution of a biphasic life history Larval dispersal is one of the most important topics in marine ecology, today. Many marine invertebrates and many fishes have a bi-phasic life cycle with a pelagic larva or pelagic eggs that can be transported over long distances, and a demersal or benthic adult. There are several theories behind why these organisms have evolved this biphasic life history: *Larva ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tympanum (anatomy)
The tympanum is an external hearing structure in animals such as mammals, birds, some reptiles, some amphibians and some insects. Using sound, vertebrates and many insects are capable of sensing their prey, identifying and locating their predators, warning other individuals, and locating potential mates and rivals by hearing the intentional or unintentional sounds they make. In general, any animal that reacts to sounds or communicates by means of sound, needs to have an auditory mechanism. This typically consists of a membrane capable of vibration known as the tympanum, an air-filled chamber and sensory organs to detect the auditory stimuli. Anurans In frogs and toads, the tympanum is a large external oval shape membrane made up of nonglandular skin. It is located just behind the eye. It does not process sound waves; it simply transmits them to the inner parts of the amphibian's ear, which is protected from the entry of water and other foreign objects. A frog's ear drum works ...

Pare Mountains
The Pare Mountains are a mountain range in northeastern Tanzania, located north of the Usambara Mountains. The mountains are administratively located in the Kilimanjaro Region, specifically in the Mwanga District and Same District. The North and South Pare mountain ranges reach a height of 2,463 meters at Shengena Peak. They are separated into North Pare Mountains and South Pare Mountains and are part of the Eastern Arc of mountains. The mountains are named after the indigenous Pare people, Pare people who reside there. Bird species in the Pare mountains include the endemic South Pare white-eye (''Zosterops winifredae''), the mountain buzzard (''Buteo oreophilus''), olive woodpecker (''Mesopicos griseocephalus''), moustached tinkerbird (''Pogoniulus leucomystax''), and the African hill babbler (''Pseudoalcippe abyssinica'').

Eastern Arc Mountains
The Eastern Arc Mountains is a chain of mountains found in Kenya and Tanzania. The chain runs from northeast to southwest, with the Taita Hills being in Kenya and the other ranges being in Tanzania. They are delimited on the southwest by the fault complex represented by the Makambako Gap that separates them from the Kipengere Range. To the northeast, they are delimited by more recent volcanism represented by Mount Kilimanjaro. The chain is considered a Tentative World Heritage Site. Mountain ranges The Eastern Arc Mountains forms a roughly crescent-shaped arc and consists of: # Taita Hills # North and South Pare Mountains # East and West Usambara Mountains # Nguru Mountains # Ukaguru Mountains # Uluguru Mountains # Uvidunda Mountains # Rubeho Mountains # Malundwe Mountain # Udzungwa Mountains # Mahenge Mountains Geology These mountain ranges are the oldest in East Africa, and though physically separated from each other, share a similar geomorphology and ecology.

Brevicipitidae
Brevicipitidae or rain frogs is a small family of frogs found in eastern and southern Africa. As of 2020 contains 37 species in 5 genera. eb application 2013. Berkeley, CaliforniaBrevicipitidae AmphibiaWeb, available at http://amphibiaweb.org/. (Accessed: 30 November 2013). Formerly included as subfamily in Microhylidae (narrow-mouth frogs), phylogenetic research has indicated the brevicipitine frogs should be considered as a family with Hemisotidae (shovelnose frogs) as the most closely related sister taxon. Most adult brevicipitine frogs are not easily seen as they spend extended periods of time in soil or leaf litter. However, some species might be partly arboreal at times. Many species show strong sexual size dimorphism, with females being much larger than males. At least the frogs in ''Breviceps'' and ''Probreviceps'' genera breed by direct development, in which small froglets emerge from eggs without intervening aquatic tadpole A tadpole is the larval stage in the b ...
