| 説明 | Ficus aurea Nuttall, 1846 - Florida strangler fig in Florida, USA. (March 2014)Plants are multicellular, photosynthesizing eucaryotes. Most species occupy terrestrial environments, but they also occur in freshwater and saltwater aquatic environments. The oldest known land plants in the fossil record are Ordovician to Silurian. Land plant body fossils are known in Silurian sedimentary rocks - they are small and simple plants (e.g., Cooksonia). Fossil root traces in paleosol horizons are known in the Ordovician. During the Devonian, the first trees and forests appeared. Earth's initial forestation event occurred during the Middle to Late Paleozoic. Earth's continents have been partly to mostly covered with forests ever since the Late Devonian. Occasional mass extinction events temporarily removed much of Earth's plant ecosystems - this occurred at the Permian-Triassic boundary (251 million years ago) and the Cretaceous-Tertiary boundary (65 million years ago).The most conspicuous group of living plants is the angiosperms, the flowering plants. They first unambiguously appeared in the fossil record during the Cretaceous. They quickly dominated Earth's terrestrial ecosystems, and have dominated ever since. This domination was due to the evolutionary success of flowers, which are structures that greatly aid angiosperm reproduction.Strangler figs are some of the most bizarre plants on Earth. They are pollinated by fig wasps (gall wasps) and seeds from ripe figs are transported in the guts of frugivores/fruit-eaters (often birds). Seeds in bird droppings that are left in other trees, usually Sabal palmetto - cabbage palm trees - germinate under proper conditions and become epiphytes. Long, slender branches extend downward from strangler fig epiphytes and eventually reach the ground. Strangler figs use nutrients from the soil to grow further and wrap themselves around the host tree, eventually shading it out and killing it. Ficus aurea is native to Florida.Classification: Plantae, Angiospermophyta, Rosales, MoraceaeLocality: grounds of Sandpiper Inn, Donax Street, Sanibel Island, southwestern Florida, USA--------------------More info. at:en.wikipedia.org/wiki/Ficus_aurea |
