Extensive kelp forests are found in the cold, nutrient-rich waters of the North Pacific and North Atlantic, especially along the coasts of California and southern South America. They grow underwater, anchored to rocky seafloors.
Where do giant bamboo forests naturally occur?
Giant bamboo species are native mainly to Asia, especially China, Southeast Asia, and parts of the Indian subcontinent. Many of the largest bamboo forests grow in tropical and subtropical mountain regions.
Where are the largest temperate rainforests with ancient trees found?
Major temperate rainforests are found on the Pacific Northwest coast of North America, including British Columbia, Washington, Oregon, and parts of Alaska. These forests contain huge conifers and ancient mossy habitats.
Where are the world's oldest known olive trees found?
Some of the oldest olive trees are found in the Mediterranean region, especially in Greece, Italy, and the Levant. A few individual trees are traditionally said to be many centuries old.
Where is the world's largest known tree ring archive used in climate science?
Major tree-ring archives are kept in research centers and museums around the world, with famous collections in the United States and Europe. The data often come from ancient bristlecone pines and other long-lived trees.
Where do myrtle beech forests survive in the wild today?
They survive in the cool temperate rainforests of Tasmania, Australia. These forests are remnants of ancient Gondwanan vegetation.
Where are the world's most famous carnivorous pitcher plants found?
Many of the best-known pitcher plants grow in Southeast Asia, especially in Borneo, Sumatra, and the Philippines. These tropical islands are biodiversity hotspots for Nepenthes species.
Where does the corpse flower naturally grow?
It is native to the rainforests of western Sumatra in Indonesia. The species is famously rare and blooms only occasionally.
Where are most wild orchids naturally found?
Wild orchids are found on every continent except Antarctica, with especially high diversity in the tropics. Southeast Asia and the Andes are among the richest orchid regions.
Where are the largest forests of giant rainforest trees found in Africa?
They are found in the Congo Basin, especially in the Democratic Republic of the Congo and neighboring Central African countries. This is the second-largest tropical rainforest region on Earth.
Where do the oldest living bristlecone pines grow?
They grow in high, dry mountain areas of the western United States, especially California, Nevada, and Utah. The oldest known individual trees are in the White Mountains of eastern California.
Where do fungi help make up the rich soils of tropical cloud forests?
They are found in mountain cloud forests in places such as Costa Rica, Ecuador, and eastern Africa. Moist, misty conditions support abundant fungal growth in leaf litter and dead wood.
Where are the oldest known fossil forests found?
Some of the earliest known fossil forests are found in places such as New York State in the United States and parts of the United Kingdom. They preserve ancient plant ecosystems from hundreds of millions of years ago.
Where do banyan trees naturally form their vast aerial-root canopies?
Banyans are native to South Asia and Southeast Asia, especially India and nearby tropical regions. Their aerial roots can spread into huge shaded groves.
Where was penicillin first discovered?

Where is the human microbiome most densely populated?
The largest and most diverse microbial population in the human body is in the large intestine, especially the colon. It contains trillions of bacteria and other microbes.
Where is the human mouth home to the most bacteria?
The mouth contains one of the body’s richest microbial communities, especially on the tongue, teeth, and gums. Dental plaque is a biofilm that forms on tooth surfaces.
Where do the bacteria that make yogurt usually grow first?
Yogurt is made by fermenting milk with bacteria that are first grown in controlled starter cultures, usually in dairy facilities. The best-known species are Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus.
Where was the first bacteria identified in pure culture isolated?
One of the first bacteria isolated in pure culture was Bacillus anthracis in Robert Koch’s laboratory work in Germany during the late 19th century. Koch’s methods helped establish modern bacteriology.
Where are hydrothermal vent bacteria found living without sunlight?
They are found on the deep ocean floor around hydrothermal vents, such as those along mid-ocean ridges. These microbes use chemical energy instead of sunlight.
Where do cyanobacteria create the pink lakes of Western Australia?
The vivid pink lakes are found in places such as Hutt Lagoon and Lake Hillier in Western Australia. Their color is linked to salt-loving microorganisms, including cyanobacteria and algae.
Where are stromatolites still formed by bacteria today?
Living stromatolites are found in a few places with shallow, salty waters, especially Shark Bay in Western Australia. They are built by microbial mats, mainly cyanobacteria.
Where did bubble wrap come from?
Hawthorne, New Jersey, in 1957. Engineer Alfred Fielding and Swiss chemist Marc Chavannes sealed two plastic shower curtains together to make textured 3-D wallpaper, trapping air bubbles by accident. The wallpaper flopped, but the bubbles turned out to be perfect for packaging.
