Christmas Boobook
The Christmas boobook (''Ninox natalis''), also known as the Christmas hawk owl, Christmas Island boobook or Christmas Island hawk owl, is a species of owl in the family Strigidae. Closely related to the hawk-owls of genus ''Ninox'', which occur in Southeast Asia and Australia, ''N. natalis'' was first classified at species level by J.J.Lister in 1888. It was not until 1998, however, that DNA testing confirmed its status as a separate species from other owls. Distribution ''Ninox natalis'' is endemic to Christmas Island, a small Australian territory of about 135 square km situated in the Indian Ocean approximately south of Java. The flora and fauna of the island face on-going threats from both human activity and introduced species of plants and animals. In addition to these threats, ''N. natalis'' is restricted to a small range on this small island and is consequently listed as vulnerable species, vulnerable by the IUCN. Phosphate mining has continued for over a century and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Gerrard Keulemans
Johannes Gerardus Keulemans (8 June 1842 – 29 March 1912) was a Dutch bird illustrator. For most of his life he lived and worked in England, illustrating many of the best-known ornithology books of the nineteenth century. Biography Keulemans was born in Rotterdam. As a young man he collected animal specimens for museums such as the Natural History Museum in Leiden, whose director, Hermann Schlegel, encouraged Keulemans and sent him on the 1864 expedition to West Africa. In 1869, he was persuaded by Richard Bowdler Sharpe to illustrate his '' Monograph of the Alcedinidae, or Family of Kingfishers'' (1868-1871) and to move to England, where he lived for the rest of his life. He was married twice, and had eight children by his first wife and seven children by his second wife. Only nine of his children reached adulthood. He also wrote topics on spirituality, and claimed he had a premonition at the moment of death of one of his sons. He died in Ilford, Essex (now part of Greater Lo ...

Birds Of Christmas Island
The birds of Christmas Island form a heterogeneous group of 162 species. There is a core group of four endemics that evolved on the remote island in the eastern Indian Ocean for thousands of years; there are also regular migrants, opportunists and occasional visitors. Christmas Island was not occupied by humans until the late 19th century and is some 200 km from the nearest land, Java. It is now an Australian territory. The natural vegetation of most of the 140 km2 island is rainforest, to which the endemic landbirds are adapted, while the seabirds have taken advantage of a breeding location which had no major natural predators. This list's taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) follow the conventions of ''The Clements Checklist of Birds of the World'', 2022 edition. The family accounts at the beginning of each heading reflect this taxonomy, as do the species counts in each family acc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cornell Lab Of Ornithology
The Cornell Lab of Ornithology is a member-supported unit of Cornell University in Ithaca, New York, which studies birds and other wildlife. It is housed in the Imogene Powers Johnson Center for Birds and Biodiversity in Sapsucker Woods Sanctuary.

Gecarcoidea Natalis
The Christmas Island red crab (''Gecarcoidea natalis'') is a species of land crab that is endemic to Christmas Island and Cocos (Keeling) Islands in the Indian Ocean. Although restricted to a relatively small area, an estimated 43.7 million adult red crabs once lived on Christmas Island alone, but the accidental introduction of the yellow crazy ant is believed to have killed about 10–15 million of these in recent years. Christmas Island red crabs make an annual mass migration to the sea to lay their eggs in the ocean. Although its population is under great assault by the ants, as of 2020 the red crab had not been assessed by the International Union for Conservation of Nature (IUCN) and it was not listed on their Red List. The crab's annual mass migration to the sea for spawning is described as an "epic" event. Millions emerge at the same time, halting road traffic and covering the ground in a thick carpet of crabs. Description Christmas Island red crabs are large crabs with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keystone Species
A keystone species is a species that has a disproportionately large effect on its natural environment relative to its abundance. The concept was introduced in 1969 by the zoologist Robert T. Paine. Keystone species play a critical role in maintaining the structure of an ecological community, affecting many other organisms in an ecosystem and helping to determine the types and numbers of various other species in the community. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether. Some keystone species, such as the wolf and lion, are also apex predators. The role that a keystone species plays in its ecosystem is analogous to the role of a keystone in an arch. While the keystone is under the least pressure of any of the stones in an arch, the arch still collapses without it. Similarly, an ecosystem may experience a dramatic shift if a keystone species is removed, even though that species was a small part of the ecosystem by measur ...

Yellow Crazy Ant
The yellow crazy ant (''Anoplolepis gracilipes''), also known as the long-legged ant or Maldive ant, is a species of ant, thought to be native to West Africa or Asia. They have been accidentally introduced to numerous places in the world's tropics. The yellow crazy ant has colloquially been given the modifier "crazy" on account of the ant's erratic movements when disturbed. Its long legs and antennae make it one of the largest invasive ant species in the world.''Anoplolepis gracilipes''. Global Invasive Species Database. ISSG.

Habitat Loss
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and Abundance (ecology), species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the Exploitation of natural resources, use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduced species, introduction of invasive species, ecosystem nutrient depletion, water pollution, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
