Likoma Island
Likoma Island is the larger of two islands in Lake Malawi, in East Africa, the smaller being the nearby Chizumulu. Likoma and Chizumulu both belong to Malawi, and together they make up the Likoma District. Although both islands lie just a few kilometres from Mozambique, and are entirely surrounded by Mozambican territorial waters, they are both exclaves of Malawi. Geography The island has an overall area of 18 km2, and is located in the north-eastern part of Lake Malawi, 7 km north-west of Cobue, Mozambique. The closest town on the Malawian coast is Chintheche. History In 1880 missionaries from the Universities' Mission to Central Africa, founded in response to a plea by David Livingstone, established their headquarters on Likoma Island. Due to the presence of British missionaries, the island was assigned to Malawi rather than Mozambique when national borders in East Africa were established after World War II. Natural environment Despite a high population density, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sentinel-2
Sentinel-2 is an Earth observation mission from the Copernicus Programme that acquires optical imagery at high spatial resolution (10 m to 60 m) over land and coastal waters. The mission's Sentinel-2A and Sentinel-2B satellites were joined in orbit in 2024 by a third, Sentinel-2C, and in the future by Sentinel-2D, eventually replacing the A and B satellites, respectively. The mission supports services and applications such as agricultural monitoring, emergencies management, land cover classification, and water quality. Sentinel-2 has been developed and is being operated by the European Space Agency. The satellites were manufactured by a consortium led by Airbus Defence and Space in Friedrichshafen, Germany. Overview The Sentinel-2 mission includes: * Multispectral image, Multi-spectral data with 13 bands in the Visible spectrum, visible, Infrared#Regions within the infrared, near infrared, and Infrared#Regions within the infrared, short wave infrared part of the Electromagnetic ...

World War II
World War II or the Second World War (1 September 1939 – 2 September 1945) was a World war, global conflict between two coalitions: the Allies of World War II, Allies and the Axis powers. World War II by country, Nearly all of the world's countries participated, with many nations mobilising all resources in pursuit of total war. Tanks in World War II, Tanks and Air warfare of World War II, aircraft played major roles, enabling the strategic bombing of cities and delivery of the Atomic bombings of Hiroshima and Nagasaki, first and only nuclear weapons ever used in war. World War II is the List of wars by death toll, deadliest conflict in history, causing World War II casualties, the death of 70 to 85 million people, more than half of whom were civilians. Millions died in genocides, including the Holocaust, and by massacres, starvation, and disease. After the Allied victory, Allied-occupied Germany, Germany, Allied-occupied Austria, Austria, Occupation of Japan, Japan, a ...

Chewa People
The Chewa are a Bantu ethnic group primarily found in Malawi and Zambia, with few populations in Zimbabwe and Mozambique. The Chewa are closely related to people in surrounding regions such as the Tumbuka. As with the Nsenga and Tumbuka, a small part of Chewa territory came under the influence of the Ngoni, who were of Zulu or Natal/ Transvaal origin. An alternative name, often used interchangeably with Chewa, is Nyanja. Their language is called Chichewa. The Chewa are mainly known for their masks and their secret societies, called Nyau. The Chewa ( Mang'anja) are a remnant of the Maravi people. There are two large Chewa clans, the Phiri and Banda, with a population of 1.5 million people. The Phiri are associated with the kings and aristocracy, the Banda with healers and mystics. History Oral records of the Chewa may be interpreted to refer to origins in Malambo, a region in the Luba area of the Democratic Republic of the Congo, from where they emigrated into north ...

Endemism
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Labidochromis Caeruleus
''Labidochromis caeruleus'' is a species of cichlid endemic to the central western coastal region of Lake Malawi in East Africa. It is also known as lemon yellow lab, the blue streak hap, the electric yellow or yellow prince, depending on the colour morph. A naturally occurring yellow-coloured variant from Lion's Cove is one of the most popular cichlids amongst aquarium hobbyists. Electric yellows inhabit water with a pH between 7.8 and 8.9 and an ideal temperature range of 23–26 °C (73.4–78.8 °F). Large males may reach in length. Reproduction This species, like the '' Astatotilapia burtoni'', is a maternal mouthbrooder, meaning the eggs are carried, hatch, and develop in the mother's mouth (buccal cavity), for about three weeks. These fish are ovophiles and the male will excavate a pit in the sand within his territory, in which the female lays the eggs; the female then takes these eggs into her mouth for fertilization. Aquarium care Electric yellows are peaceful co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cichlids
Cichlids () are a large, diverse, and widespread family of Percomorpha, percomorph fish in the family (biology), family Cichlidae, order Cichliformes. At least 1,760 species have been Binomial nomenclature, scientifically described, making it one of the largest vertebrate families, with only the Cyprinidae being more speciose. New species are discovered annually, and many species remain Undescribed taxon, undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. They are native to the Neotropics, Africa (including Madagascar), the Middle East, and the Indian subcontinent, although some species have been introduced worldwide. Many cichlids, particularly tilapia, are important food fishes, while others, such as the ''Cichla'' species, are valued game fish. The family also includes many popular freshwater aquarium fish fishkeeping, kept by hobbyists, including the freshwater angelfish, angelfish, Astronotus ocellatus, oscar ...

Crocodile
Crocodiles (family (biology), family Crocodylidae) or true crocodiles are large, semiaquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia. The term "crocodile" is sometimes used more loosely to include all extant taxon, extant members of the order (biology), order Crocodilia, which includes the alligators and caimans (both members of the family Alligatoridae), the gharial and false gharial (both members of the family Gavialidae) as well as other extinct Taxon, taxa. Crocodile Measurement, size, Morphology (biology), morphology, behaviour and ecology differ among species. However, they have many similarities in these areas as well. All crocodiles are semiaquatic and tend to congregate in freshwater habitats such as rivers, lakes, wetlands and sometimes in brackish water and Seawater, saltwater. They are carnivorous animals, feeding mostly on vertebrates such as fish, reptiles, birds and mammals, and sometimes on invertebrates such as mol ...

Platyoides
''Platyoides'' is a genus of spiders belonging to the family Trochanteriidae. Its members are known as scorpion spiders and are found in sub-Saharan Africa and its islands, Madagascar, Réunion, Aldabra and the Canary Islands. The genus is nocturnal in habit and has developed extreme flattening of the body adapted to living in narrow cracks, particularly under loose bark. Origin of the word 'Platyoides' The ancient Greek language is the basis a vast array of scientific terminology. The word '''Platyoides''' is a compound word broken up into two distinct parts. The first element of the word '''Platyoides''' is 'Platy'. The ancient Greek definition of 'Platy' means broad and flat. This first section of the word directly relates to the asethic genetic makeup of the genus. The second element of the word which also originates from the Ancient Greek language is 'oid'. 'Oid' means 'form of'. Together the two segments of this compound word confirms this distinct feature of the fla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invertebrate
Invertebrates are animals that neither develop nor retain a vertebral column (commonly known as a ''spine'' or ''backbone''), which evolved from the notochord. It is a paraphyletic grouping including all animals excluding the chordata, chordate subphylum Vertebrata, i.e. vertebrates. Well-known Phylum, phyla of invertebrates include arthropods, molluscs, annelids, echinoderms, flatworms, cnidarians, and sponges. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxon, taxa have a greater number and diversity of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 10 Micrometre, μm (0.0004 in) myxozoans to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are actually sister chordate subphyla to Vertebrata, being more closely related to vertebrates than to other invertebrates. This makes the "invertebrates" para ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibian
Amphibians are ectothermic, anamniote, anamniotic, tetrapod, four-limbed vertebrate animals that constitute the class (biology), class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all Tetrapod, tetrapods, but excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant taxon, extant (living) amphibians belong to the monophyletic subclass (biology), subclass Lissamphibia, with three living order (biology), orders: Anura (frogs and toads), Urodela (salamanders), and Gymnophiona (caecilians). Evolved to be mostly semiaquatic, amphibians have adapted to inhabit a wide variety of habitats, with most species living in freshwater ecosystem, freshwater, wetland or terrestrial ecosystems (such as riparian woodland, fossorial and even arboreal habitats). Their biological life cycle, life cycle typically starts out as aquatic animal, aquatic larvae with gills known as tadpoles, but some species have devel ...

Reptile
Reptiles, as commonly defined, are a group of tetrapods with an ectothermic metabolism and Amniotic egg, amniotic development. Living traditional reptiles comprise four Order (biology), orders: Testudines, Crocodilia, Squamata, and Rhynchocephalia. About 12,000 living species of reptiles are listed in the Reptile Database. The study of the traditional reptile orders, customarily in combination with the study of modern amphibians, is called herpetology. Reptiles have been subject to several conflicting Taxonomy, taxonomic definitions. In Linnaean taxonomy, reptiles are gathered together under the Class (biology), class Reptilia ( ), which corresponds to common usage. Modern Cladistics, cladistic taxonomy regards that group as Paraphyly, paraphyletic, since Genetics, genetic and Paleontology, paleontological evidence has determined that birds (class Aves), as members of Dinosauria, are more closely related to living crocodilians than to other reptiles, and are thus nested among re ...
