San Cristobal (Solomon Islands)
The island of Makira (also known as San Cristobal and San Cristóbal) is the largest island of Makira-Ulawa Province in the Solomon Islands. It is third most populous island after Malaita and Guadalcanal, with a population of 55,126 as of 2020. The island is located east of Guadalcanal and south of Malaita. The largest and capital city is Kirakira. History The first recorded sighting by Europeans of Makira was by the Spanish expedition of Álvaro de Mendaña in June 1568. More precisely the sighting and also landing in San Cristobal was due to a local voyage that set out from Guadalcanal in a small boat, in the accounts the brigantine ''Santiago'', commanded by Alférez Hernando Enriquez and having Hernán Gallego as pilot. They charted it as ''San Cristóbal''.Brand, Donald D. ''The Pacific Basin: A History of its Geographical Explorations'' The American Geographical Society, New York, 1967, p.133.

Threatened
Threatened species are any species (including animals, plants and fungi) which are vulnerable to endangerment in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of ''critical depensation'', a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment. IUCN definition The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened: *Vulnerable species *Endangered species * Critically endangered species Less-than-threatened categories are near threatened, least concern, and the no longer assigned category of conservation dependent. Species which have not been evaluated (NE), or do not have sufficient data (data deficient) also are not considered "t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pied Goshawk
The pied goshawk (''Accipiter albogularis'') is a species of bird of prey in the family Accipitridae. It is found on Bougainville Island and the Solomon Islands. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial ....

White-headed Fruit Dove
The white-headed fruit dove (''Ptilinopus eugeniae'') is a species of bird in the pigeon family Columbidae. It was described by the English ornithologist John Gould in 1856, and the specific name ''eugeniae'' honours the French empress Eugénie de Montijo. Adults of the species have white heads, a purplish-red breast patch, a grey shoulder patch, olive-green , greenish with a blue tinge, and a yellowish . Juveniles have green heads with the white restricted to the forehead and upper throat, a much smaller grey shoulder patch, and the red breast patch restricted to the centre of the breast. The species is endemic to Makira and the nearby islands of Ugi and Malaupaina in the Solomon Islands. It inhabits lowland, hill, and ridge forest, along with neighbouring agricultural areas, and is especially common in foothills. Its diet consists of small-seeded fruits and berries. The International Union for Conservation of Nature considers it near-threatened. Although it can adapt to d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The chestnut-bellied imperial pigeon (''Ducula brenchleyi'') is a species of bird in the family Columbidae. It is endemic to the southern Solomon Islands. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. It is threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species.

Crested Cuckoo-dove
The crested cuckoo-dove (''Reinwardtoena crassirostris'') is a species of bird in the family Columbidae. It is endemic to the Solomon Islands archipelago. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. It is threatened by habitat loss. Taxonomy and systematics The crested cuckoo-dove was originally described in 1859 as ''Turacoena crassirostris'' by John Gould on the basis of a specimen from Guadalcanal in the Solomon Islands. It was then moved to the monotypic genus ''Coryphoenas'' by Robert Wardlaw-Ramsay in 1890. The generic name ''Reinwardtoena'' is in honor of the naturalist Caspar Reinwardt, combining his name with the Ancient Greek word ''oinas'', meaning pigeon. The specific name ''crassirostris'' is from the Latin words ''crassus'', meaning thick, and ''rostris'', meaning billed. Crested cuckoo-dove is the official common name designated by the International Ornithologists' Union. Other common na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Melanesian Scrubfowl
The Melanesian scrubfowl or Melanesian megapode (''Megapodius eremita'') is a megapode species that is endemic to islands within Melanesia. The Melanesian scrubfowl has a unique strategy of egg incubation in which it relies on environmental heat sources. This bird species is culturally important for Indigenous peoples in Melanesia. Taxonomy and systematics Two names are commonly used to refer to the species ''Megapodius eremita'': the Melanesian scrubfowl and Melanesian megapode. ''M. eremita'' belongs to the family Megapodiidae (the megapodes) and genus Megapodius (the scrubfowl). Following this classification, some taxonomists prefer the common designation "scrubfowl" because it is more precise, identifying the species as part of its particular genus rather than the megapode family as a whole. The species ''M. eremita'' was first described and introduced to 'Western' taxonomy by Hartlaub in 1867. But, as later taxonomists struggled to identify whether scrubfowl groups were distin ...

Population Growth
Population growth is the increase in the number of people in a population or dispersed group. Actual global human population growth amounts to around 83 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7.9 billion in 2020. The UN projected population to keep growing, and estimates have put the total population at 8.6 billion by mid-2030, 9.8 billion by mid-2050 and 11.2 billion by 2100. However, some academics outside the UN have increasingly developed human population models that account for additional downward pressures on population growth; in such a scenario population would peak before 2100. World human population has been growing since the end of the Black Death, around the year 1350. A mix of technological advancement that improved agricultural productivity and sanitation and medical advancement that reduced mortality increased population growth. In some geographies, this has slowed through the process called the demographic tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...
