The blue tilapia (Oreochromis aureus) is a species of tilapia, a fish in the family Cichlidae. [2] Native to Northern and Western Africa, and the Middle East, through introductions it is now also established elsewhere, including parts of the United States, where it has been declared an invasive species and has caused significant environmental damage.

Quercus douglasii, known as blue oak, is a species of oak endemic to California, common in the Coast Ranges and the foothills of the Sierra Nevada. [4] It is California's most drought-tolerant deciduous oak, [5] and is a dominant species in the blue oak woodland ecosystem. It is occasionally known as mountain oak and iron oak. [6] [7]
Also, hybrids between certain parent combinations (such as between Mozambique and Wami tilapia) result in offspring that are all or predominantly male. Male tilapia are preferred in aquaculture as they grow faster and have a more uniform adult size than females. The "Florida Red" tilapia is a popular commercial hybrid of Mozambique and blue ...

California's oldest tree, a Palmer's oak thought to be 13,000 to 18,000 years old, may be threatened by a proposed development, environmentalists say.
California oak woodland occurs in moist areas usually up to 4,900 feet (1,500 m). [6] [5]: 387 These woodlands include oak species, such as coast live oak (Quercus agrifolia), canyon live oak (Quercus chrysolepis), and Engelmann's oak (Quercus engelmannii).
There are concerns that Mozambique tilapia will invade the rivers of the Murray-Darling Basin. [18] [19] As tilapia can thrive in fresh, brackish and salt water habitats, [20] it is thought that tilapia can quickly infest neighbouring rivers. Tilapia, like eels or bull sharks, can enter new river systems via the sea.
