Tsimanampetsotsa
Lake Tsimanampetsotsa () (also called Lake Tsimanampesotse) is a moderately Soda lake, alkaline lake in the Toliara Province, in the southwestern part of Madagascar. It is located at around . The lake is protected within Tsimanampetsotsa National Park and it is also within a Ramsar site. The Ramsar list of wetlands of international importance, Ramsar site has a total area of , while the surface of the lake is much smaller. The name of the lake in Malagasy language, Malagasy means "lake without dolphins". It is a sacred place for worship, ceremonies and rituals. Local taboos prevent water pollution. Swimming and the utilisation of pirogues is prohibited. Water, mud and some plants from the lake are used in traditional medicine (Tahirindraza and Marikandia 2015).Rasoloariniaina, JR. 2017.

Tsimanampetsotsa National Park
Tsimanampetsotsa National Park also spelt Tsimanampetsotse, and known as Tsimanampetsotsa Nature Reserve is a 432 km2 national park on the south-west coast of Madagascar in the region Atsimo-Andrefana. The park is south of Toliara and south of the capital, Antananarivo. Route Nationales (RN) 10 to Faux Cap passes the park and the nearest airport is at Toliara. The national park contains and is named after Lake Tsimanampetsotsa. History and Significance Tsimanampetsotsa National Park encompasses the westernmost escarpment of the limestone Mahafaly Plateau. It was first protected in 1927 for its endemic flora and fauna and became a national park in 1966. It is within the Madagascar spiny forests or "spiny desert" of southern Madagascar, a globally distinctive ecoregion. This is the area with the highest level of plant endemism in Madagascar, with 48% of the genera and 95% of the species endemicElmqvist T, Pyyko ̈nen M, Tengo ̈M, Rakotondrasoa F, Rabakonandrianina E, et al ...

Ramsar List Of Wetlands Of International Importance
Ramsar sites are protected under by the Ramsar Convention, an international treaty for the conservation movement, conservation and sustainable use of wetlands, recognizing the fundamental ecological functions of wetlands and their economic, cultural, scientific, and recreational value. The convention establishes that "wetlands should be selected for the list on account of their international significance in terms of ecology, botany, zoology, limnology or hydrology." Over the years, the Conference of the Contracting Parties has adopted more specific criteria interpreting the convention text. The Ramsar List organizes the Ramsar sites according to the contracting party that designated each to the list. Contracting parties are grouped into six "regions": Africa, Asia, Europe, Latin American and the Caribbean, North America, and Oceania. , 171 states have acceded to the convention and designated 2,531 sites to the list, covering ; one other state has acceded to the convention but has ye ...

Toliara Province
The Toliara Province (formerly Toliary or Tuléar) is a former province of Madagascar with an area of . It had a population of 2,229,550 (July, 2001). Its capital was Toliara. Near Toliara was the " spiny forest". Toliara Province bordered the following provinces – Mahajanga Province in the north, Antananarivo Province in the northeast and Fianarantsoa Province in the east. Economy and population Masikoro Malagasy and Tandroy Malagasy were the chief languages. Sea cucumbers were exported from the province and were an important factor in its economy. The deciduous Andronovory forest was located in the province. The province was the poorest one in Madagascar. In 1993, 8 in every 10 person of the province was living below the poverty line. Despite the production of export crops the province recorded the highest rural poverty. The average fertility rate per woman was above 5. With 77 percent of its population being illiterate, Tolaira was the most illiterate province of Madagascar. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acrostichum Aureum
''Acrostichum'' is a fern genus in the Parkerioideae subfamily of the Pteridaceae. It was one of the original pteridophyte genera delineated by Linnaeus. It was originally drawn very broadly, including all ferns that had sori apparently "acrostichoid", or distributed in a uniform mass across the back of the frond, rather than organized in discrete sori. This led Linnaeus to include such species as '' Asplenium platyneuron'' in the genus, because the specimen he received had sori so crowded that it appeared acrostichoid. Since '' Acrostichum aureum'' is regarded as the type for the genus, it is now narrowly circumscribed only to the natural genus of three species, that are allied to the genus '' Ceratopteris''. They are collectively known as the leather ferns or leather swamp ferns, genus members commonly being found in swamps. The species of ''Acrostichum'' are massive ferns, with fronds up to tall, that depend on a semi-aquatic existence. They do not withstand prolonged imm ...

Naucoridae
Naucoridae is a small family of insects commonly known as the creeping water bugs and saucer bugs. They are similar in appearance and behavior to Belostomatidae (giant water bugs), but considerably smaller, at long. Naucoridae are found around the world, but the greatest diversity is in tropical regions. They inhabit a wide range of freshwater habitats, ranging from still waters like ponds, to flowing rivers and even torrential streams. There are eight subfamilies containing about 400 species in 46 genera. One of these subfamilies is Pelocoris, and the species within this group are usually found in ponds or quiet bodies of water. They are predators that feed on other small invertebrates. Munhoz, I. L. A., Serrão, J. E., de Melo, A. L., Martins, L. C. B., & Araújo, V. A. (2022).

Elmidae
Elmidae, commonly known as riffle beetles, is a family of beetles in the superfamily Byrrhoidea described by John Curtis in 1830. Both adults and larvae are usually aquatic, living under rocks in fast-flowing shallow areas of streams, such as riffles, feeding on algae and biofilms. There are more than 150 genera and 1,500 described species in Elmidae. The oldest record of the group is '' Cretohypsilara'' from the Cenomanian aged Burmese amber Burmese amber, also known as Burmite or Kachin amber, is amber from the Hukawng Valley in northern Myanmar. The amber is dated to around 100 million years ago, during the latest Albian to earliest Cenomanian ages of the mid-Cretaceous period. Th ....

Hydroptilidae
The Hydroptilidae are a large family of caddisflies (Trichoptera) with a worldwide distribution. They are commonly known as microcaddisflies or purse-case caddisflies, in reference to two characteristic traits of this family: Hydroptilidae are much smaller than other caddisflies, rarely exceeding in length. Their larvae do not build a protective case until the final instar of their growth. At that time however, they build a typically Purse-shaped case, either portable or stuck to the substrate, in which the larva finishes growth and pupates. Systematics and taxonomy Their systematic placement among the caddisflies is still disputed. They are traditionally placed in the suborder Spicipalpia, which do not seem to be a natural monophyletic group, but rather an evolutionary grade of moderately advanced caddisflies. Some authors downrank the Spicipalpia to a superfamily of the more basal Annulipalpia and call them Rhyacophiloidea (which otherwise refers to a subfamily of suborder ...

Dytiscidae
The Dytiscidae, from the Ancient Greek word δυτικός (''dystikos''), meaning "able to dive", are the predaceous diving beetles, a family of water beetles. They occur in virtually any freshwater habitat around the world, but a few species live in terrestrial habitats such as among leaf litter. The “diving” in their common name comes from their cycling between underwater and the surface to replenish oxygen like a diver. The adults of most are between long, though much variation is seen between species. The European '' Dytiscus latissimus'' and Brazilian '' Bifurcitus ducalis'' are the largest, reaching up to respectively, although the latter is listed as extinct by the IUCN. In contrast, the smallest is likely the Australian '' Limbodessus atypicali'' of subterranean waters, which only is about long. Most are dark brown, blackish, or dark olive in color with golden highlights in some subfamilies. The larvae are commonly known as water tigers due to their voracious appe ...
