Paul V
Pope Paul V ( la, Paulus V; it, Paolo V) (17 September 1550 – 28 January 1621), born Camillo Borghese, was head of the Catholic Church and ruler of the Papal States from 16 May 1605 to his death in January 1621. In 1611, he honored Galileo Galilei as a member of the Papal Accademia dei Lincei and supported his discoveries. In 1616, Pope Paul V instructed Cardinal Bellarmine to inform Galileo that the Copernican theory could not be taught as fact, but Bellarmine's certificate allowed Galileo to continue his studies in search for evidence and use the geocentric model as a theoretical device. That same year Paul V assured Galileo that he was safe from persecution so long as he, the Pope, should live. Bellarmine's certificate was used by Galileo for his defense at the trial of 1633. Early life Camillo Borghese was born in Rome on 17 September 1550 into the Borghese family of Siena which had recently established itself in Rome. He was the eldest son of seven sons of th ...

Cichlid
Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses ( Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. The closest living relative of cichlids is probably the convict blenny, and both families are classified in the 5th edition of ''Fishes of the World'' as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. 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 aquariu ...

Betsiboka River
Betsiboka River is a long river in central-north Madagascar. It flows northwestward and empties to Bombetoka Bay, forming a large river delta, delta. It originates to the east of Antananarivo. The river is surrounded in mangroves. The river is distinctive for its red-coloured water, which is caused by river sediments. The river carries an enormous amount of reddish-orange silt to the sea. Much of this silt is deposited at the mouth of the river or in the bay. It is dramatic evidence of the catastrophic erosion of northwestern Madagascar. Removal of the native forest for cultivation and pastureland during the past 50 years has led to massive annual soil losses approaching 250 metric tonnes per hectare (112 tons per acre) in some regions of the island, the largest amount recorded anywhere in the world. Several fish species are Endemism, endemic to the river basin, including the three cichlids ''Kotso, Paretroplus petiti'', ''Paretroplus tsimoly, P. tsimoly'' and ''Damba mipentina, P ...

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Oxylapia Polli
''Oxylapia'' is a genus of freshwater fish in the family Cichlidae. It contains the single species ''Oxylapia polli'', known locally as the songatana. It is an endangered species, endemic to the Marolambo Rapids in the Nosivolo River (a tributary of the Mangoro River) in east-central Madagascar. It is threatened by habitat loss and sedimentation caused by deforestation. The only other monotypic cichlid genus in Madagascar is ''Katria'', and it is restricted to the same region as ''Oxylapia''. In 2010, the Nosivolo River was designated as a Ramsar Site.Durrell Wildlife Conservation Trust (20 September 2010). Nosivolo is designated as Madagascar's first riverine Ramsar site.'
