[4] [8] Overall, during the Late Pleistocene about 65% of all megafaunal species worldwide became extinct, [9] rising to 72% in North America, 83% in South America and 88% in Australia, [10] with all mammals over 1,000 kilograms (2,200 lb) becoming extinct in Australia and the Americas, [1] and around 80% globally.

The O‘ahu ‘ō‘ō (Moho apicalis) is among dozens of bird species that became extinct after the human settlement of Hawaii. This is a list of Hawaiian animal species extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before present (about 9700 BCE ) [ a ] and continues to ...
Located about 2,300 miles (3,680 km) from the nearest continental shore, the Hawaiian Islands are the most isolated group of islands on the planet. The plant and animal life of the Hawaiian archipelago is the result of early, very infrequent colonizations of arriving species and the slow evolution of those species—in isolation from the rest of the world's flora and fauna—over a period of ...
The volcano is steep-sided, and it usually has a defined caldera and has two or more rift zones radiating from the summit. The type of lava erupted in this stage of activity is alkali basalt. [4] Due to stretching forces, the development of two or more rift zones is common. The lava accumulates in a shallow magma storage reservoir. [5]
During the Late Pleistocene, particularly from around 50,000 years ago onwards, most large mammal species became extinct, including 80% of all mammals greater than 1,000 kilograms (2,200 lb), while small animals were largely unaffected. This pronouncedly size-biased extinction is otherwise unprecedented in the geological record.
The terrain that the volcanoes developed on includes both old volcanic rocks of the Koʻolau volcano, sediments of the coastal plains, [4] and soils. [68] Some Honolulu Volcanics have grown on coral deposits, [ 37 ] Koko Head developed on limestone for example, [ 80 ] and coral reef development was widespread during the activity of the Honolulu ...
Possibly natural aridification or habitat degradation and prey loss caused by human activity.

Mauna Kea (/ ˌ m ɔː n ə ˈ k eɪ ə, ˌ m aʊ n ə-/, [6] Hawaiian: [ˈmɐwnə ˈkɛjə]; abbreviation for Mauna a Wākea) [7] is a dormant shield volcano on the island of Hawaiʻi. [8] Its peak is 4,207.3 m (13,803 ft) above sea level, making it the highest point in Hawaii and the island with the second highest high point, behind New Guinea, the world's largest tropical island with ...
