Lake Tsimanampetsotsa (french: Lac Tsimanampetsotsa) (also called Lake Tsimanampesotse) is a moderately 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 site has a total area of , while the surface of the lake is much smaller. The name of the lake in 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 a ...

Ramsar List Of Wetlands Of International Importance
This is the list of Wetlands of International Importance as defined by the Ramsar Convention for the 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. , 170 states have acceded to the convention and designated 2,471 sites to the list, covering ; two other states have acceded to the convention but have yet to des ...

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. 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. Only 22 percent of the p ...

Casuarina Equisetifolia
''Casuarina equisetifolia'', common names ''Coastal She-oak'' or ''Horsetail She-oak'' (sometimes referred to as the Australian pine tree or whistling pine tree outside Australia), is a Casuarinaceae, she-oak species of the genus ''Casuarina''. The native range extends throughout Southeast Asia, Northern Australia and the Pacific Islands; including Thailand, Myanmar, Vietnam, Malaysia, Singapore, Brunei, Indonesia, East Timor, and the Philippines (where it is known as agoho pine), east to Papua New Guinea, French Polynesia, New Caledonia, and Vanuatu, and south to Australia (north of Northern Territory, north and east Queensland, and north-eastern New South Wales). Populations are also found in Madagascar, but it is doubtful if this is within the native range of the species. The species has been introduced to the Southern United States and West Africa. It is an invasive species in Florida, South Africa, India and Brazil. Taxonomy ''Casuarina equisetifolia'' was officially d ...

Veliidae
Veliidae is a family of gregarious predatory insects in the suborder Heteroptera. They are commonly known as riffle bugs, small water striders, or broad-shouldered water striders because the segment immediately behind the head is wider than the rest of the abdomen. The genus ''Rhagovelia'' is also referred to as a ripple bug. Veliidae have a specialized body plan that allows them to walk on water and are neuston. Gerridae is another closely related group that is also neuston and both are in the superfamily Gerroidea. Veliidae are smaller however, between . They can be found on ponds, near lake shores, and in rivers worldwide. Some species can also be found on plants near water, in salt water or in mud flats. Life cycle Like all Heteroptera, the Veliidae go through an egg, nymph and adult stage. They have four or five nymphal instars. Both the adults and nymphs live together gregariously, in loose communities and can often be found in large groups. Eggs are usually laid underwa ...

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 about 400 species in 46 genera in 8 subfamilies. They were formerly united in a superfamily Naucoroidea with the Aphelocheiridae and Potamocoridae, but these are now in their own superfamily ( Aphelocheiroidea) and the Naucoroidea are monotypic. Genera These 46 genera belong to the family Naucoridae: * '' Afronaucoris'' Sites, 2022 * '' Ambrysus'' Stål, 1862 * '' Aneurocoris'' Montandon, 1897 * '' Aptinocoris'' Montandon, 1897 * '' Asthenocoris'' Usinger, 1937 * '' Australambrysus'' Reynoso & Sites, 2021 * '' Australonaucoris'' Sites ...

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. ....

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 sub ...

Dytiscidae
The Dytiscidae – based on the Greek ''dytikos'' (δυτικός), "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 among leaf litter. The adults of most are between long, though much variation is seen between species. The European '' Dytiscus latissimus'' and Brazilian '' Megadytes ducalis'' are the largest, reaching up to and respectively. 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 appetite. They have short, but sharp mandibles and immediately upon biting, they deliver digestive enzymes into prey to suck their liquefied remains. The family includes more than 4,000 described species in numerous genera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
