ʻakepa
''Loxops'' is a Hawaiian honeycreeper genus in the finch family (biology), family, Fringillidae. Most of them are commonly known as akepa. Taxonomy There are 5 species in this genus, two of which are recently extinct or possibly extinct: Molecular analysis supports the genus diverging from its closest relatives, the ''Chlorodrepanis'' ʻAmakihi (other), ʻamakihis, during the earliest Pleistocene, about 2.47 million years ago. The clade containing both genera is Sister group, sister to the genus ''ʻAnianiau, Magumma'', which contains the ʻAnianiau, ʻanianiau, from which they diverged during the latest Pliocene, about 2.78 million years ago. Genetic analysis of the extant species supports ''L. mana'' as being the most basal extant member of the group, diverging from the other species slightly later in the Pleistocene at about 1.9 million years ago, with ''L. coccineus'' and ''L. caeruleirostris'' diverging 600,000 years after ''L. mana''.

Maui ʻakepa
The Maui ʻakepa (''Loxops ochraceus'') is an Bird extinction, extinct species of ʻakepa that was endemic to Maui in the Hawaiian Islands. It was once common throughout the island, but introduced mosquitoes and other animals to Maui contributed to the declining population, and the bird has been listed as Extinction, extinct by the IUCN Red List, IUCN Red List of Threatened Species since 2024. The latest confirmed sighting of this bird was in 1988, and in 2021 the United States Fish and Wildlife Service proposed declaring it extinct. The species was delisted from the Endangered Species Act of 1973, Endangered Species Act on October 16, 2023 citing extinction. Description It was a four-inch (10 cm) long bird of a dusty green color. It had a small cross bill just like the other ''Loxops'' species. Its call was a slight quivering whistle ending with a long trill. It appeared as a small fast moving ball of fluff of green, as it flew from tree to tree. Feeding It ate spiders an ...

Hakalau Forest National Wildlife Refuge
Hakalau Forest National Wildlife Refuge is a protected area on the Hawaii (island), Big Island of Hawaii. It is one of two units, along with the Kona Forest National Wildlife Refuge that is managed as part of the Big Island National Wildlife Refuge Complex. Access to the Kona Forest is restricted since it contains several endangered species. Description Hakalau Forest NWR contains some of the finest remaining stands of native Hawaiian tropical rainforests#Wet forests, montane wet forest in Hawaii. The slopes below feet receive very high rainfall - annually. Hawaiian tropical rainforests#Bogs, Bogs, fern patches, and scrubby forest dominate this area, which is dissected by numerous deep gulches. Rainfall decreases to about at elevations above , where majestic koa (''Acacia koa'') and red-blossomed ōhia lehua (''Metrosideros polymorpha'') trees form a closed-canopy (biology), canopy forest. Further upslope, above , rainfall decreases to or less and native forest merges into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acacia Koa
''Acacia koa'', commonly known as koa, is a species of Flowering plant, flowering tree in the Family (biology), family Fabaceae. It is Endemism, endemic to the Hawaiian Islands, where it is the second most common tree. The highest populations are on Hawaii (island), Hawaii, Maui and Oahu, Oahu. Name The name ''koa'' in the Hawaiian language ultimately comes from Proto-Austronesian language, Proto-Austronesian *''teRas'' meaning "core" or "ironwood"; many names referring to certain ironwood or heartwood species in Southeast Asia and Oceania such as ''Vitex parviflora'' (''tugás'' in Cebuano language, Cebuano), ''Eusideroxylon zwageri'' (''togas'' in Tombonuwo language, Tombonuwo), and ''Intsia bijuga'' (''dort'' in Palauan language, Palauan) descend from this root. The Hawaiian Acacia koa is closely related to a common tree in Taiwan called ''Acacia confusa''. The two species also share a very similar appearance. ''Koa'' also means brave, bold, fearless, or warrior. Description ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metrosideros Polymorpha
''Metrosideros polymorpha'', the ''ōhia lehua'',; is a species of flowering evergreen tree in the Myrtus, myrtle family, Myrtaceae, that is Endemism, endemic to the six largest Hawaiian Islands, islands of Hawaii, Hawaii. It is a member of the diverse ''Metrosideros'' genus, which are widespread over the southwest Pacific. It is the state tree of Hawai'i. It is a highly variable tree, being tall in favorable situations, and a much smaller prostrate shrub when growing in Hawaiian tropical rainforests#Bogs, boggy soils or directly on basalt. It produces a brilliant display of flowers, made up of a mass of stamens, which can range from fiery red to yellow. Many native Hawaiian traditions refer to the tree and the forests it forms as sacred to Pele (deity), Pele, the volcano goddess, and to Laka, the goddess of hula. Ōhia trees grow easily on lava, and are usually the first plants to grow on new lava flows. ''Metrosideros polymorpha'' is commonly called a ''lehua'' tree, or an ' ...

Breed
A breed is a specific group of breedable domestic animals having homogeneous appearance (phenotype), homogeneous behavior, and/or other characteristics that distinguish it from other organisms of the same species. In literature, there exist several slightly deviating definitions. Breeds are formed through genetic isolation and either natural adaptation to the environment or selective breeding, or a combination of the two. Despite the centrality of the idea of "breeds" to animal husbandry and agriculture, no single, scientifically accepted definition of the term exists. A breed is therefore not an objective or biologically verifiable classification but is instead a term of art amongst groups of breeders who share a consensus around what qualities make some members of a given species members of a nameable subset. Another point of view is that a breed is consistent enough in type to be logically grouped together and when mated within the group produce the same type. When bred togeth ...

Loxia
Crossbills are birds of the genus ''Loxia'' within the finch family (Fringillidae), with six species. These birds are characterized by the mandibles with crossed tips, which gives the group its English name. Adult males tend to be red or orange in color, and females green or yellow, but there is much variation. Crossbills are specialist feeders on conifer cones, and the unusual bill shape is an adaptation which enables them to extract seeds from cones. These birds are typically found in higher northern hemisphere latitudes, where their food sources grow. They irrupt out of the breeding range when the cone crop fails. Crossbills breed very early in the year, often in winter months, to take advantage of maximum cone supplies. Systematics and evolution The genus ''Loxia'' was introduced by the Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of Systema Naturae, 10th edition of his ''Systema Naturae''. The name is from the Ancient Greek , "crosswise". The Swiss naturalis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passerines
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped') which includes more than half of all bird species. Sometimes known as perching birds, passerines generally have an anisodactyl arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest order of birds and one of the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al. (2003Evolution, biogeography, and patterns of diversification in passerine birds ''J. Avian Biol'', 34:3–15.Selvatti, A.P. et al. (2015"A Paleogene origin for crown passerines and the diversification of the Oscines in the New World" ''Molecular Phylogenetics and Evolution'', 88:1–15. Passerines are divided into three suborders: New Zealand wrens; Suboscines, primarily found in North and South America; and songbirds. Passerines originated in the Sou ...

IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and Data analysis, analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through buildin ...

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pliocene
The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58See the 2014 version of the ICS geologic time scale million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic, Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.59 to 1.81 Ma, and is now included in the Pleistocene. As with other older geologic periods, the Stratum, geological strata that define the start and end are well-identified but the exact dates of the start a ...
