The mata mata, mata-mata, or matamata (Chelus fimbriata) [7] is a South American species of freshwater turtle found in the Amazon basin and river system of the eastern Guianas. It was formerly believed to also occur in the Orinoco basin, western Guianas and upper Rio Negro – Branco system, but in 2020 these populations were found to belong to ...
The main roots are 6–10 ft (1.8–3.0 m) deep, and the plants send out strong, tough rhizomes, so it forms very strong sod. [4] Depending on soil and moisture conditions, it grows to a height of 1–3 m (3.3–9.8 ft). The stem base turns blue or purple as it matures. Big bluestem blooms in the summer and seeds into the fall.
Pando being the heaviest tree and the largest tree by landmass, while also being the largest aspen clone leaves the Pando Tree in a class of its own. Since the early 2000s, little information has been adequately corroborated about Pando's origins and how its genetic integrity has been sustained over a long period of time, conservatively between ...
A genetic analysis of the mata mata was reported in 2020, which showed a deep split between two of its populations. The authors proposed that the mostly Orinoco population be assigned to a new species, Chelus orinocensis, with the Amazon population retaining the Chelus fimbriatus species designation.
Two main opposing forces affect a tree's height; one pushes it upward while the other holds it down. By analyzing the interplay between these forces in coast redwoods (Sequoia sempervirens), a team of biologists led by George Koch of Northern Arizona University calculated the theoretical maximum tree height or the point at which opposing forces balance out and a tree stops growing.
The California Floristic Province is a world biodiversity hotspot as defined by Conservation International, due to an unusually high concentration of endemic plants: approximately 8,000 plant species in the geographic region, and over 3,400 taxa limited to the CFP proper, as well as having lost over 70% of its primary vegetation. A biodiversity ...
Genipa americana trees are up to 30 m tall and up to 60 cm dbh. [2] [3] [4] Their bark is smooth with little fissures. [4] The leaves are opposite, obovate, or obovate oblong, 10–35 cm long, 6–13 cm wide, and glossy dark green, with entire margin, acute or acuminate apex, and attenuated base. [2] [5] [3] The inflorescences are cymes up to ...
The Blue Mountains ecoregion is a Level III ecoregion designated by the United States Environmental Protection Agency (EPA) in the Pacific Northwest, mainly in the state of Oregon, with small areas over the state border in Idaho and southeastern Washington. It is also contiguous with the World Wildlife Fund's Blue Mountain forests ecoregion.
