All of the species have soft, pithy wood. Scalesia species have been called "the Darwin's finches of the plant world" because they show a similarly dramatic pattern of adaptive radiation. One of the largest and most widespread species is Scalesia pedunculata – a large tree which grows up to 15 to 20 metres tall, reaching maturity in a few ...
Scalesia pedunculata is a flowering plant species in the family Asteraceae, growing to a slender tree (20m tall, DBH 20 cm), and found in dense stands on the humid windward coasts of the islands of Santa Cruz, San Cristobal, Santiago and Floreana in the Galapagos Islands. The Galapagos archipelago lies in the southeast trade wind zone, so that ...
Opuntia galapageia is a species of cactus. It is endemic to the Galápagos Islands, part of Ecuador. Forms occurring on different islands have been treated as separate species and subtaxa of these species. Opuntia echios, Opuntia helleri, Opuntia insularis, Opuntia megasperma, Opuntia myriacantha and Opuntia saxicola are now sunk within O ...
The Galápagos Islands are home to a remarkable number of endemic species. The stark rocky islands (many with few plants) made it necessary for many species to adapt to survive and by doing so evolved into new species. It was after visiting the Galápagos and studying the wildlife that a young Charles Darwin developed his theory of evolution. [2]
The fauna of the Galápagos Islands include a total of 9,000 confirmed species. Of them, none have been introduced by humans, and seventeen are endemic. [citation needed] Due to amphibians intolerance of saltwater, no amphibians naturally occur on the Galapagos Islands.
However, a 2021 study analyzing the level of divergence within the extinct West Indian Chelonoidis radiation and comparing it to the Galápagos radiation found that the level of divergence within both clades may have been significantly overestimated, and supported once again reclassifying all Galápagos tortoises as subspecies of a single ...
Of California's total plant population, 2,153 species, subspecies, and varieties are endemic and native to California alone, according to the 1993 Jepson Manual study. [4] This botanical diversity stems not only from the size of the state, but also its diverse topographies , climates, and soils (e.g. serpentine outcrops ).
Bursera graveolens, known in Spanish as palo santo ('sacred wood'), is a wild tree native to the Yucatán Peninsula and also found in Peru and Venezuela. [2]Bursera graveolens is found in the seasonally dry tropical forests of Peru, Venezuela, Colombia, Ecuador, Panama, Costa Rica, Nicaragua, Honduras, Guatemala, and El Salvador, [3] and on the Galápagos Islands.
