Extinct and Extirpated Plants from Oregon By JIMMY KAGAN and SUSAN VRILAKAS

چکیده
Oregon is one of the most diverse states in the U.S., containing between six and ten nationally recognized ecoregions, depending on various ecoregion classifications. The state includes habitats which range from the moist and mild coast redwood forests of Curry County to the extremely dry playas of the Alvord Desert. Elevations range from coastal salt marshes at sea level, to alpine peaks over 9,000 feet. Each habitat provides unique opportunities for plant evolution.

Prehistoric extinction of birds on Mangaia, Cook Islands, Polynesia.
Mangaia (Cook Islands) consists of a weathered volcanic interior encircled by limestones known as the makatea. Excavations at Tangatatau Rockshelter (site MAN-44), located on the inner cliff of the makatea, produced a stratified sequence of Polynesian artifacts and faunal remains ranging from A.D. 1000-1100 to A.D. 1500-1600. Resident species of birds represented at MAN-44 include nine seabirds...
متن کاملThorn-like prickles and heterophylly in Cyanea: adaptations to extinct avian browsers on Hawaii?
The evolution of thorn-like structures in plants on oceanic islands that lack mammalian and reptilian herbivores is puzzling, as is their tendency toward juvenile-adult leaf dimorphism. We propose that these traits arose in Cyanea (Campanulaceae) on Hawaii as mechanical and visual defenses against herbivory by flightless geese and goose-like ducks that were extirpated by Polynesians within the ...
متن کاملThe progressive effect of the individualistic response of species to Quaternary climate change: an analysis of British mammalian faunas
The individualistic response of species to climate change is accepted by many although how this process works across several climate oscillations has not been widely considered. A cluster analysis using the Bray–Curtis metric with single linkage to show relative faunal similarity was performed on successively older British mammalian faunas to investigate whether they become progressively differ...
متن کاملReassembling island ecosystems: the case of Lord Howe Island
Exotic species that invade remote islands, usually following human settlement, have had catastrophic effects on native biota. However, on islands it is increasingly feasible to eradicate key exotic species allowing extant native species to recover in situ or to return naturally. The practice of marooning threatened species on islands where the threat is absent, irrespective of whether the threa...
متن کاملExtremophile culture collection from extreme area of Iran
The number of studies on extremophilic organisms has grown exponentially in the last few years. These exotic organisms (extremoplilees) are adapted to living at 100 c. In volcanic springs, at low temperatures in the cold polar seas, at high pressure in the deep sea, at very low and high ph values (ph 0-1 or ph 10-11) or at hight salt concentration (35%). Recent developments clearly show that ce...
