Leptopelis Modestus
''Leptopelis modestus'' is a species of frog in the family Arthroleptidae. Its common names are modest forest treefrog and plain tree frog. Distribution and taxonomy ''Leptopelis modestus'' was described in 1898 by Franz Werner, an Austrian zoologist and explorer, based on specimens (syntypes) collected from Cameroon. The reported distribution varies by source, partly depending on whether the stated distribution accounts for recently described species (e.g., '' Leptopelis mtoewaate'', '' Leptopelis mackayi''). According to the Amphibian Species of the World, ''Leptopelis modestus'' is only found in southeastern Nigeria and Cameroon. The IUCN Red List (2008) also mentions the island of Bioko (Equatorial Guinea) and eastern Democratic Republic of Congo, but remarks that the latter likely refers to a (then) undescribed species. ''Leptopelis fiziensis'' from eastern Democratic Republic of Congo and western Tanzania was originally included in this species as a subspecies. Descriptio ...

Franz Werner
Franz Josef Maria Werner (15 August 1867 in Vienna – 28 February 1939 in Vienna) was an Austrian zoologist and explorer. Specializing as a herpetologist and entomologist, Werner described numerous species and other taxa of frogs, snakes, insects, and other organisms. His father introduced him at age six to reptiles and amphibians. A brilliant student, he corresponded often with George Albert Boulenger (1858–1937) and Oskar Boettger (1844–1910) who encouraged his studies with these animals. Werner obtained his doctorate in Vienna in 1890 and then after spending a year in Leipzig, began to teach at the Vienna Institute of Zoology. In 1919, he became tenured as a professor, maintaining this title until his retirement in 1933. Although working close to the Vienna Natural History Museum, he could not use their herpetological collections, after the death of its director, Franz Steindachner (1834–1919), who did not like Werner, and had barred him from accessing the coll ...

Amphibians Described In 1898
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 dec ...

Frogs Of Africa
The fauna of Africa, in its broader sense, is all the animals living in Africa and its surrounding seas and islands. The more characteristic African fauna is found in the Afrotropical realm. Lying almost entirely within the tropics, and equally to north and south of the equator creates favourable conditions for rich wildlife. Africa is home to many of the world's most famous fauna in human culture such as lions‚ rhinos‚ cheetahs‚ giraffes‚ antelope, hippos, leopards, zebras‚ and African elephants among many others. Origins and history of African fauna Whereas the earliest traces of life in fossil record of Africa date back to the earliest times, the formation of African fauna as we know it today, began with the splitting up of the Gondwana supercontinent in the mid-Mesozoic era. After that, four to six faunal assemblages, the so-called African Faunal Strata (AFSs) can be distinguished. The isolation of Africa was broken intermittently by discontinuous "filter routes" tha ...

Leptopelis
''Leptopelis'' is a genus of frogs in the family Arthroleptidae. They are found throughout Sub-Saharan Africa, excluding Madagascar. It is placed in monotypic subfamily Leptopelinae, although this subfamily is not always recognized. They have a number of common names, including forest treefrogs, tree frogs, leaf-frogs, and big-eyed frogs. Description ''Leptopelis'' are mostly medium-sized frogs (snout–vent length ), but '' Leptopelis palmatus'' can reach . Tympanum is present. Most species have expended digit tips. Ecology ''Leptopelis'' are mainly arboreal, but some species, especially in more arid areas, are terrestrial or even subfossorial. Breeding typically starts with the heavy rains in the beginning of the wet season. Eggs may be deposited either in water or in/on the ground. Development includes a free-living tadpole stage, with a possible exception of '' Leptopelis brevirostris'', whose large eggs suggest that development could be direct. Males typically call in bu ...

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexual Selection In Amphibians
Sex is the biological distinction of an organism between male and female. Sex or SEX may also refer to: Biology and behaviour *Animal sexual behaviour **Copulation (zoology) **Human sexual activity ** Non-penetrative sex, or sexual outercourse ** Sex drive, a person's overall sexual drive or desire for sexual activity ** Sexual intercourse, also called copulation or coitus *Gender, the distinction between male and female or masculinity and femininity within an individual's gender identity **Sex and gender distinction *Human sexuality *Mating types, a distinction of gametes, whether in anisogamous or isogamous species *Sexing, the act of discerning the sex of an animal *Sexual reproduction, a process of combining and mixing genetic traits, associated with the generation of new individuals, by means of meiosis and fertilization **Genetic recombination, the process of mixing genetic traits solely, occurring both in organisms with sexual or asexual reproduction Art and entertainme ...

Leptopelis Aubryi
''Leptopelis aubryi'', also known as the Aubry's tree frog and Gaboon forest treefrog, is a species of frog in the family Arthroleptidae. It is found in southeastern Nigeria, Cameroon, Central African Republic, Equatorial Guinea, Gabon, Republic of the Congo, western and northern Democratic Republic of the Congo, and Angola (Cabinda Enclave and extreme northeastern contiguous Angola). Etymology The specific name ''aubryi'' refers to Charles Eugène Aubry-Lecomte, a French colonial administrator and an amateur naturalist. Taxonomy ''Leptopelis aubryi'' is similar to ''Leptopelis spiritusnoctis'' (referred to as ''Leptopelis hyloides'' prior to 2007) from West Africa, and they have sometimes been treated as conspecific. However, acoustic (male calls) and genetic data support their treatment as separate species. In fact, the large variation of call characteristics in ''L. aubryi'' could indicate that the current delimitation of this species might hide a complex of cryptic specie ...
