John Cassin
John Cassin (September 6, 1813 – January 10, 1869) was an American ornithologist from Pennsylvania. He worked as curator and Vice President at the Philadelphia Academy of Natural Sciences and focused on the systemic classification of the Academy's extensive collection of birds. He was one of the founders of the Delaware County Institute of Science and published several books describing 194 new species of birds. Five species of North American birds, a cicada and a mineral are named in his honor. Early life and education Cassin was born in Upper Providence Township, Pennsylvania on September 6, 1813. He was educated at the Westtown School in Westtown, Pennsylvania. His great Uncle, John Cassin, was a commodore in the U.S. Navy and served in the War of 1812.

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ...

Birds Of Malesia
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have 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 loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. ...

Ducula
''Ducula'' is a genus of the pigeon family Columbidae, collectively known as imperial pigeons. They are large to very large pigeons with a heavy build and medium to long tails. They are arboreal, feed mainly on fruit and are closely related to the other genus of fruit-eating doves, ''Ptilinopus''. Both genera display brightly coloured plumage, predominantly green, often with contrasting under-parts of purple, orange or red. Some ''Ducula'' have prominently swollen ceres. They have large gapes and swallow seeds whole, playing an important role in seed dispersal. Imperial pigeons are found in forests of southern Asia, New Guinea, northern Australia and the Pacific islands. Many species are nomadic, travelling long distances to exploit seasonal fruit sources. Some undertake migrations and all are strong fliers. Because of habitat loss and predation, species of ''Ducula'' are amongst the most threatened of avian species globally. Taxonomy The genus ''Ducula'' was introduced in 183 ...

Black Rat
The black rat (''Rattus rattus''), also known as the roof rat, ship rat, or house rat, is a common long-tailed rodent of the stereotypical rat genus ''Rattus'', in the subfamily Murinae. It likely originated in the Indian subcontinent, but is now found worldwide. The black rat is black to light brown in colour with a lighter underside. It is a generalist omnivore and a serious pest to farmers because it feeds on a wide range of agricultural crops. It is sometimes kept as a pet. In parts of India, it is considered sacred and respected in the Karni Mata Temple in Deshnoke. Taxonomy ''Mus rattus'' was the scientific name proposed by Carl Linnaeus in 1758 for the black rat. Three subspecies were once recognized, but today are considered invalid and are now known to be actually color morphs: *''Rattus rattus rattus'' – roof rat *''Rattus rattus alexandrinus'' – Alexandrine rat *''Rattus rattus frugivorus'' – fruit rat Characteristics A typical adult black rat is long, n ...

Macaque
The macaques () constitute a genus (''Macaca'') of gregarious Old World monkeys of the subfamily Cercopithecinae. The 23 species of macaques inhabit ranges throughout Asia, North Africa, and (in one instance) Gibraltar. Macaques are principally frugivorous (preferring fruit), although their diet also includes seeds, leaves, flowers, and tree bark. Some species, such as the crab-eating macaque, subsist on a diet of invertebrates and occasionally small vertebrates. On average, southern pig-tailed macaques in Malaysia eat about 70 large rats each per year. All macaque social groups are matriarchal, arranged around dominant females. Macaques are found in a variety of habitats throughout the Asian continent and are highly adaptable. Certain species have learned to live with humans and have become invasive in some human-settled environments, such as the island of Mauritius and Silver Springs State Park in Florida. Macaques can be a threat to wildlife conservation as well as to hum ...

Philippine Cockatoo
The red-vented cockatoo (''Cacatua haematuropygia''), also known as the Philippine cockatoo and locally katala, abukay, agay or kalangay, is a species of cockatoo. It is Endemism, endemic to the Philippines though pressured by various environmental degradation and illegal pet trades, the population of the Philippine cockatoo is somehow growing owing to Katala Organization.It is roughly the size and shape of the Tanimbar corella, but is easily distinguished by the red feathers around the vent. It is threatened by habitat loss and the cage-bird trade. Description The plumage is all white with red undertail coverts tipped white, yellowish undertail and pale yellow underwings. It is long and has an wingspan. Ebird describes it is "A rare large parrot of forest on Palawan and several other scattered islands. Heavily persecuted.

Rasa Island
Rasa Island is a flat coral island in the Sulu Sea just off the coast of the municipality of Narra in Palawan, Philippines. It is a shallow island surrounded by mangroves and tidal flats containing one of the country's last remaining coastal forests. The island is home to the largest population of the endemic and critically endangered Philippine cockatoo in the wild in the Philippines. It was declared a protected area in 2006. Geography Rasa Island is a large irregular mangrove swamp on a coral reef that extends about beyond the island at its southwest and northeast ends. It is located about from Casuarina Point and forms the northeastern side of Mantaquin Bay. Only one-third of the island is permanently dry with the remaining two-thirds exposed to the occasional tides. To its north lie Arena Island and other small coralline islands on the coast of Aborlan. To the south across the Mantaquin Bay are Linda and Emelina islands. Rasa Island is administered as part of the Narra b ...

Tunku Abdul Rahman National Park
The Tunku Abdul Rahman National Park ( ms, Taman Negara Tunku Abdul Rahman) comprises a group of 5 islands located between Kota Kinabalu in Sabah, Malaysia. The park is spread over 4,929 hectares, two-thirds of which cover the sea. Before the Ice age, it formed part of the Crocker Range mass of sandstone and sedimentary rock on the mainland. However, about one million years ago, the melting ice brought about changes in the sea level and parts of the mainland were cut off by the sea to form the islands of Gaya, Sapi, Manukan, Mamutik and Sulug. Evidence of this can be seen from the exposed sandstone of the coastline forming the cliffs, caves, honeycombs and deep crevices. The park was named after Tunku Abdul Rahman, Malaysia's first Prime Minister. Jesselton Point Ferry Terminal in downtown Kota Kinabalu is the ferry terminal for those heading to the islands in Tunku Abdul Rahman National Park (Gaya, Sapi, Manukan, Mamutik and Sulug). This ferry terminal is also the departure ...

Turtle Islands National Park (Malaysia)
Turtle Islands Park (''Taman Pulau Penyu'') is located within the Turtle Islands, which lie in the Sulu Sea some north of Sandakan in Sabah, Malaysia. It consists of 3 islands - Selingaan, Little Bakkungan and Gulisaan (often spelt with -an instead of the traditional -aan), including the surrounding coral reefs and ocean. The Park is noted for its green turtles and hawksbill turtles which lay their eggs on the beaches of the islands. The Park covers an area of 17.4 km². The name Turtle Islands, however, refers to 10 islands, 3 of which are part of Turtle Islands Park of Malaysia, and 7 which belong to the Turtle Islands Wildlife Sanctuary of Tawi-Tawi province, Philippines. On 1 August 1966, the first turtle hatchery in Malaysia was established on Selingan, funded entirely by the Sabah state government. Turtle hatcheries on the remaining two islands followed shortly after. In 1972, Selingan, Bakkungan Kechil and Gulisan were designated as a Game and Bird Sanctuary. In ...

Illegal Logging
Illegal logging is the harvest, transportation, purchase or sale of timber in violation of laws. The harvesting procedure itself may be illegal, including using corrupt means to gain access to forests; extraction without permission, or from a protected area; the cutting down of protected species; or the extraction of timber in excess of agreed limits. Illegal logging is a driving force for a number of environmental issues such as deforestation, soil erosion and biodiversity loss which can drive larger scale environmental crisis such as climate change and other forms of environmental degradation. Illegality may also occur during transport, such as illegal processing and export (through fraudulent declaration to customs); the avoidance of taxes and other charges, and fraudulent certification. These acts are often referred to as "wood laundering". Illegal logging is driven by a number of economic forces, such as demand for raw materials, land grabbing and demand for pasture for ...
