John Hewitt (herpetologist)
John Hewitt (23 December 1880 – 4 August 1961) was a South African zoologist and archaeologist of British origin. He was born in Dronfield, Derbyshire, England, and died in Grahamstown, South Africa. He was the author of several herpetological papers which described new species. He also described new species of spiders and other arachnids. Biography He graduated with a first-class in natural sciences from Jesus College, Cambridge in 1903. From 1905 to 1908 he was Curator of the Sarawak Museum in Kuching, Sarawak. In 1909 he went to South Africa to work as an assistant curator at the Transvaal Museum in Pretoria.

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, introdu ...

Amphibians Described In 1933
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 ...

Strongylopus
''Strongylopus'' ('strongylos'=round, 'pus'=foot) is a genus of pyxicephalid frogs native to Africa. They are found in the area from southwestern South Africa and Namibia to northern Tanzania. Their common name is stream frogs. Description ''Strongylopus'' are small to medium-sized frogs: adult snout–vent lengths are typically in the range of . Species within this genus may be found at altitudes from sea level up to 3250 m in elevation. They generally occur in riparian habitats, including fynbos heath, grassland, montane flooded grassland, savanna and forest edge. Some species occur in more specific habitats, such as '' Strongylopus kilimanjaro'' in alpine moorland near cold water streams. Species These species belong to this genus: * '' Strongylopus bonaespei'' (Dubois, 1981) – Banded stream frog * '' Strongylopus fasciatus'' (Smith, 1849) – Striped stream frog * '' Strongylopus fuelleborni'' (Nieden, 1911) – Fuelleborn's stream frog * ''Strongylopus grayii'' (Smi ...

Gorongosa National Park
Gorongosa National Park is at the southern end of the Great African Rift Valley in the heart of central Mozambique, Southeast Africa. The more than park comprises the valley floor and parts of surrounding plateaus. Rivers originating on nearby Mount Gorongosa () water the plain. Seasonal flooding and waterlogging of the valley, which is composed of a mosaic of soil types, creates a variety of distinct ecosystems. Grasslands are dotted with patches of acacia trees, savannah, dry forest on sands and seasonally rain-filled pans, and termite hill thickets. The plateaus contain miombo and montane forests and a spectacular rain forest at the base of a series of limestone gorges. This combination of unique features at one time supported some of the densest wildlife populations in all of Africa, including charismatic carnivores, herbivores, and over 500 bird species. But large mammal numbers were reduced by as much as 95% and ecosystems were stressed during the Mozambican Civil War (197 ...

Eastern Highlands
:''"Eastern Highlands" also refers to Eastern Highlands Province in Papua New Guinea, and part of the Great Dividing Range, Australia.'' The Eastern Highlands, also known as the Manica Highlands, is a mountain range on the border of Zimbabwe and Mozambique. The Eastern Highlands extend north and south for about through Zimbabwe's Manicaland Province and Mozambique's Manica Province. The Highlands are home to the Eastern Zimbabwe montane forest-grassland mosaic ecoregion. The ecoregion includes the portion of the highlands above 1000 meters elevation, including the Inyangani Mountains, Bvumba Mountains, Chimanimani Mountains, Chipinge Uplands, and the isolated Mount Gorongosa further east in Mozambique. The Southern miombo woodlands ecoregion lies at lower elevations east and west of the highlands. The highlands have a cooler, moister climate than the surrounding lowlands, which support distinct communities of plants and animals. The ecoregion is home to several plant commun ...

Chirinda Forest Botanical Reserve
The Chirinda Forest Botanical Reserve is situated on the slopes of Mount Selinda, south of Chipinge, in the Chipinge Highlands of Manicaland, Zimbabwe, and is administered by the Forestry Commission. The reserve is situated at between in altitude, and receives some to of annual rainfall. of its higher levels, above , is covered by moist evergreen forest, specifically Zanzibar-Inhambane transitional rain forest, of which it represents the southernmost occurrence. The headwaters of three streams, namely the Zona, Chinyika and Musangazi, drain the two broad highlands which it encloses. The boundaries of the reserve are not strictly enforced, so that cattle grazing and plant harvesting are ongoing. The reserve is surrounded by communal settlements, commercial timber plantations (eucalypts and pines) and small-scale commercial farming units. The naturalist Charles Swynnerton was appointed manager of the nearby Gungunyana farm in 1900, and a number of plant, bird and insect names ...

Type (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 al ...

River
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as Stream#Creek, creek, Stream#Brook, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to Geographical feature, geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "Burn (landform), burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from Precipitation (meteorology), precipitation through a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frog
A frog is any member of a diverse and largely Carnivore, carnivorous group of short-bodied, tailless amphibians composing the order (biology), order Anura (ανοὐρά, literally ''without tail'' in Ancient Greek). The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar, but molecular clock, molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 Myr, million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from Taxonomy (biology), taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subtropical Or Tropical High-altitude Grassland
Montane grasslands and shrublands is a biome defined by the World Wildlife Fund. The biome includes high elevation grasslands and shrublands around the world. The term "montane" in the name of the biome refers to "high elevation", rather than the ecological term which denotes the region below treeline. This biome includes high elevation (montane and alpine) grasslands and shrublands, including the puna and páramo in South America, subalpine heath in New Guinea and East Africa, steppes of the Tibetan plateaus, as well as other similar subalpine habitats around the world. The plants and animals of tropical montane páramos display striking adaptations to cool, wet conditions and intense sunlight. Around the world, characteristic plants of these habitats display features such as rosette structures, waxy surfaces, and abundant pilosity. The páramos of the northern Andes are the most extensive examples of this habitat type. Although ecoregion biotas are most diverse in the Ande ...
