Hyuganatsu (Citrus tamurana, Japanese: 日向夏) is a citrus fruit and plant grown in Japan. The name comes from Hyūga , the ancient name of Miyazaki Prefecture in Kyushu , where the citrus is said to have originated, while "natsu" ( 夏 ) means summer.
Miyazaki Prefecture is on the eastern coast of the island of Kyushu, surrounded by the Pacific Ocean to the south and east, Ōita Prefecture to the north, and Kumamoto and Kagoshima prefectures to the west. It is one of only two locations on Earth where the fungus Chorioactis geaster is found. [5] Miyazaki is the home of the hyuganatsu fruit.
Marine microorganisms are defined by their habitat as microorganisms living in a marine environment, that is, in the saltwater of a sea or ocean or the brackish water of a coastal estuary. A microorganism (or microbe ) is any microscopic living organism or virus , which is invisibly small to the unaided human eye without magnification .
The N 2-fixing Trichodesmium spp., which commonly occurs in tropical and sub-tropical waters, is of large environmental significance in fertilizing the ocean with important nutrients. b. Trichodesmium can establish massive blooms in nutrient poor ocean regions with high dust deposition, partly due to their unique ability to capture dust, center ...
Like the Hyuganatsu, the white pith (albedo) may be eaten. [ 4 ] The rind's cold-pressed oil has been studied for fragrance factors, and was found to contain limonene (roughly 80%), followed by the monoterpene Gamma-terpinene (10%), trans beta- farnesene , and myrcene , [ 7 ] showing similarity to Hyuganatsu's peel profile, though with ...
Mineral calcium carbonate most commonly presents as calcite in the ocean, and the majority of calcite is produced biologically in the upper layer of the ocean. CaCO 3 material is exported from the upper ocean to sediments on the ocean floor where it either dissolves or is buried. [ 44 ]
Seagrass stoichiometry does not follow the Redfield ratio commonly used as an indicator of nutrient availability for phytoplankton growth. In fact, a number of studies from around the world have found that the proportion of C:N:P in seagrasses can vary significantly depending on their species, nutrient availability, or other environmental factors.
Seagrass cell walls contain the same polysaccharides found in angiosperm land plants, such as cellulose [101] However, the cell walls of some seagrasses are characterised by sulfated polysaccharides, [102] [103] which is a common attribute of macroalgae from the groups of red, brown and also green algae.
