Thalassia Hemprichii
''Thalassia hemprichii'', called Pacific turtlegrass, is a widespread species of seagrass in the genus '' Thalassia'', native to the shores of the Indian Ocean, the Red Sea, and the western Pacific Ocean. Its growth rate increases with CO2 enrichment, and it can tolerate lowered light conditions caused by algal blooms, allowing for it to respond positively to ocean acidification Ocean acidification is the reduction in the pH value of the Earth’s ocean. Between 1751 and 2021, the average pH value of the ocean surface has decreased from approximately 8.25 to 8.14. The root cause of ocean acidification is carbon dioxid ... and other disturbances.

Hermann Zu Solms-Laubach
Hermann zu Solms-Laubach, more precisely Hermann Maximilian Carl Ludwig Friedrich Graf zu Solms-Laubach (23 December 1842 in Laubach, Grand Duchy of Hesse – 24 November 1915 in Strasbourg) was a German botanist. Life Count Solms-Laubach studied in Giessen, Berlin, Fribourg and Geneva. In 1868 he obtained habilitation at the University of Halle-Wittenberg. In 1872 he became an associate professor at the University of Strasbourg; in 1879 he was appointed professor and director of the botanical garden in Göttingen, and in 1888 in Strasbourg. From October 1883 to March 1884 he traveled in Java and stayed for 3 months at Buitenzorg (now Bogor, especially in the botanical garden), West Java and made several collections in the vicinity of Cibodas. He wrote a paper about the Bogor Botanical Gardens that he loved so much. He was a member of the Linnean Society, the Royal Society, the Geographic Society; and recipient of the Gold Medal of the Linnean Society in 1911. Work His work ...

Seagrass
Seagrasses are the only flowering plants which grow in marine environments. There are about 60 species of fully marine seagrasses which belong to four families (Posidoniaceae, Zosteraceae, Hydrocharitaceae and Cymodoceaceae), all in the order Alismatales (in the clade of monocotyledons). Seagrasses evolved from terrestrial plants which recolonised the ocean 70 to 100 million years ago. The name ''seagrass'' stems from the many species with long and narrow leaves, which grow by rhizome extension and often spread across large "meadows" resembling grassland; many species superficially resemble terrestrial grasses of the family Poaceae. Like all autotrophic plants, seagrasses photosynthesize, in the submerged photic zone, and most occur in shallow and sheltered coastal waters anchored in sand or mud bottoms. Most species undergo submarine pollination and complete their life cycle underwater. While it was previously believed this pollination was carried out without pollinators ...

Ocean Acidification
Ocean acidification is the reduction in the pH value of the Earth’s ocean. Between 1751 and 2021, the average pH value of the ocean surface has decreased from approximately 8.25 to 8.14. The root cause of ocean acidification is carbon dioxide emissions from human activities which have led to atmospheric carbon dioxide (CO2) levels of more than 410 ppm (in 2020). The oceans absorb CO2 from the atmosphere. This leads to the formation of carbonic acid (H2CO3) which dissociates into a bicarbonate ion () and a hydrogen ion (H+). The free hydrogen ions (H+) decrease the pH of the ocean, therefore increasing acidity (this does not mean that seawater is acidic yet; it is still alkaline, with a pH higher than 8). A decrease in pH corresponds to a decrease in the concentration of carbonate ions, which are the main building block for calcium carbonate (CaCO3) shells and skeletons. Marine calcifying organisms, like mollusks, oysters and corals, are particularly affected by this as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrocharitaceae
Hydrocharitaceae is a flowering plant family including 16 known genera with a total of ca 135 known species (Christenhusz & Byng 2016), that including a number of species of aquatic plant, for instance the tape-grasses, the well known Canadian waterweed, and frogbit. The family includes both freshwater and marine aquatics. They are found throughout the world in a wide variety of habitats, but are primarily tropical. Description The species are annual or perennial, with a creeping monopodial rhizome with the leaves arranged in two vertical rows, or an erect main shoot with roots at the base and spirally arranged or whorled leaves. The leaves are simple and usually found submerged, though they may be found floating or partially emerse. As with many aquatics they can be very variable in shape – from linear to orbicular, with or without a petiole, and with or without a sheathing base. The flowers are arranged in a forked, spathe-like bract or between two opposite bracts. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
