Lānaʻi ʻalauahio
The Lānaʻi ʻalauahio (''Paroreomyza montana montana'') is an extinct subspecies of Hawaiian honeycreeper, found on much of the island of Lana'i in the Hawaiian archipelago. It apparently was common until the early 1900s, when there appeared to have been a steep decline in birds on the island. It was similar to the Maui alauahio and this species may have reacted similarly to its existing relative, to which it was considered conspecific. This bird was one of several to vanish from Lana'i, along with others such as the Lanai hookbill. The extinction of this species was primarily driven by habitat degradation. Apparently the many forest plants of Lana'i had become displaced, rare or even extinct as a result of human activity. With settlers came a host of invasive plants from Europe and other continents. The nail in the coffin for the 'alauahio may have been the destruction of forest associated with the construction of the island's main city, Lanai City. Though not much of its ...

Extant Taxon
Neontology is a part of biology that, in contrast to paleontology, studies and deals with living (or, more generally, '' recent'') organisms. It is the study of extant taxa (singular: extant taxon): taxa (such as species, genera and families) with members still alive, as opposed to (all) being extinct. For example: * The Indian elephant (''Elephas maximus'') is an extant species, and the woolly mammoth (''Mammuthus primigenius'') is an extinct species. * The moose (''Alces alces'') is an extant species, and the Irish elk (''Megaloceros giganteus'') is an extinct species. * In the group of molluscs known as the cephalopods, there were approximately 600 extant species and 7,500 extinct species. A taxon can be classified as extinct if it is broadly agreed or certified that no members of the group are still alive. Conversely, an extinct taxon can be reclassified as extant if there are new discoveries of living species (" Lazarus species"), or if previously known extant species ...

Lanai City, Hawaii
Lānai is the sixth-largest of the Hawaiian Islands and the smallest publicly accessible inhabited island in the chain. It is colloquially known as the Pineapple Island because of its past as an island-wide pineapple plantation. The island's only settlement of note is the small town of Lānai City. The island is 98% owned by Larry Ellison, cofounder and chairman of Oracle Corporation; the remaining 2% is owned by the state of Hawaii or individual homeowners. Lānai has a land area of , making it the 43rd largest island in the United States. It is separated from the island of Molokai by the Kalohi Channel to the north, and from Maui by the Auau Channel to the east. The United States Census Bureau defines Lānai as Census Tract 316 of Maui County. Its total population rose to 3,367 as of the 2020 United States census, up from 3,193 as of the 2000 census and 3,131 as of the 2010 census. As visible via satellite imagery, many of the island's landmarks are accessible only by d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Extinctions Since 1500
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 common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have 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 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 fur ...

Extinct Birds Of Hawaii
Extinction is the termination of an organism by the death of its last member. A taxon may become functionally extinct before the death of its last member if it loses the capacity to reproduce and recover. As a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, and mammoths. Through evolution, species arise through the process of speciation. Species become extinct when they are no longer able to survive in changing conditions or against superio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hawaiian Honeycreepers
Hawaiian honeycreepers are a group of small birds endemic to Hawaii. They are members of the finch family Fringillidae, closely related to the rosefinches (''Carpodacus''), but many species have evolved features unlike those present in any other finch. Their great morphological diversity is the result of adaptive radiation in an insular environment. Many have been driven to extinction since the first humans arrived in Hawaii, with extinctions increasing over the last two centuries following European discovery of the islands, with habitat destruction and especially invasive species being the main causes. Taxonomy Before the introduction of molecular phylogenetic techniques, the relationship of the Hawaiian honeycreepers to other bird species was controversial. The honeycreepers were sometimes categorized as a family Drepanididae,Clements, J. 2007. ''The Clements Checklist of the Birds of the World.'' 6th ed. other authorities considered them a subfamily, Drepanidinae, of Frin ...

Paroreomyza
''Paroreomyza'' is a genus of Hawaiian honeycreeper in the subfamily Carduelinae of the family Fringillidae. These birds are endemic to Hawaii. Taxonomy ''Paroreomyza'', along with '' Oreomystis'' (although their alliance is disputed), is the second most basal genus of Hawaiian honeycreeper to survive to recent times, with the most basal being the recently extinct poʻouli (''Melamprosops phaeosoma''), with ''Paroreomyza'' and ''Oreomystis'' having diverged from the rest of the lineage about 4.7 million years ago. Members of ''Paroreomyza'' do not have two key phenotypic traits present in ''Oreomystis'' and the more derived Hawaiian honeycreepers: a distinct musty odor and a squared-off tongue. Following the extinction of the poʻouli, it (along with ''Oreomystis'' if they are considered sister genera) is the most basal group of Hawaiian honeycreepers still surviving, although it too has lost most of its species. Species It includes the following species: * Kākāwahie (''Pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ʻula-ʻai-hawane
The ula-ai-hāwane (''Ciridops anna'') is an extinct species of small Hawaiian honeycreeper. The term ''ula-ai-hāwane'' is a Hawaiian language, Hawaiian phrase translating to "red [bird] that eats ''hāwane''". It was only ever reported from the forested mountains of the Kohala, Hawaii, Kohala, Hilo and Kona District, Hawaiʻi, Kona districts on the island of Hawaii (island), Hawaii. Fossil remains reveal that it (and at least one closely related species, ''Ciridops tenax'') also existed at one time on other Hawaiian islands. The species is named after Anna Dole, wife of Sanford B. Dole. Description The average length of the bird was around . With respect to coloring, the adult was patterned red overall, while the head, throat, and upper back were silvery gray. The crown, wings, breast, shoulder, and tail were black, and the tertials a white color. The legs and bill were yellowish. Immature birds were brownish overall with a bluish-gray breast, black wings and tail, and a gree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invasive Plants
An invasive species is an introduced species that harms its new environment. 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 web. Since the 20th century, invasive species have become serious economic, social, and environmental threats worldwide. 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 invasion. For millennia, humans have served as both accidental and deliberate dispersal agents, beginning with their earliest migrations, accelerating in the Age of Discovery, and accelerating again with the spread of international trade. Notable invasive plant species include the kudzu vine, giant hogweed (''Heracleum mantegazzianum''), Japanese knotweed (''Re ...
