Nordal Wille
Johan Nordal Fischer Wille (28 October 1858 – 4 February 1924) was a Norwegian botanist. He was a professor at the Royal Frederick University from 1893 to his death, founded the laboratory at the University Botanical Garden and co-founded the Natural History Museum. Personal life Wille was born in Hobøl as the son of physician Hans Georg Wille (1803–1879) and his wife Ingeborg Fischer (1811–1875). He was a grandnephew of priest and writer Hans Jacob Wille. He married three times. The first marriage with Anne Koller, a daughter of Carl Theodor Fredrik Koller, lasted from September 1891 to her death in March 1908. During this period he was a brother-in-law of Rasmus Meyer and Gustav Guldberg, who were married to two of Anne's sisters. The second marriage with Ragna Margrethe Knudsen lasted from September 1911 to her death in July 1917, and finally he married Swedish-born school teacher Ester Victoria Svensson in October 1918.

Seaweed
Seaweed, or macroalgae, refers to thousands of species of macroscopic, multicellular, marine algae. The term includes some types of '' Rhodophyta'' (red), ''Phaeophyta'' (brown) and ''Chlorophyta'' (green) macroalgae. Seaweed species such as kelps provide essential nursery habitat for fisheries and other marine species and thus protect food sources; other species, such as planktonic algae, play a vital role in capturing carbon, producing at least 50% of Earth's oxygen. Natural seaweed ecosystems are sometimes under threat from human activity. For example, mechanical dredging of kelp destroys the resource and dependent fisheries. Other forces also threaten some seaweed ecosystems; a wasting disease in predators of purple urchins has led to a urchin population surge which destroyed large kelp forest regions off the coast of California. Humans have a long history of cultivating seaweeds for their uses. In recent years, seaweed farming has become a global agricultural practic ...

Ulvaceae
Ulvaceae () is a widely distributed family of thin green algae having either a flat or a hollow tubular thallus, reproducing by the conjugation of planogametes or of zoospores, and being classed among the Ulotrichales or now more commonly placed in the order Ulvales. Genera in the family Ulvaceae * ''Enteromorpha'' * '' Enteronia'' * ''Gemina'' * '' Letterstedtia'' * ''Lobata'' * ''Ochlochaete'' * ''Percursaria'' * ''Phycoseris'' * ''Ruthnielsenia'' * '' Solenia'' * ''Ulva'' * '' Ulvaria'' * ''Umbraulva The genus ''Umbraulva'', which is a green alga within the Ulvaceae family, was proposed by Bae and Lee in 2001. The genus initially contained the three species that were initially studied to develop the genus, and since has had three new species ad ...''

Alaska
Alaska ( ; russian: Аляска, Alyaska; ale, Alax̂sxax̂; ; ems, Alas'kaaq; Yup'ik: ''Alaskaq''; tli, Anáaski) is a state located in the Western United States on the northwest extremity of North America. A semi-exclave of the U.S., it borders the Canadian province of British Columbia and the Yukon territory to the east; it also shares a maritime border with the Russian Federation's Chukotka Autonomous Okrug to the west, just across the Bering Strait. To the north are the Chukchi and Beaufort Seas of the Arctic Ocean, while the Pacific Ocean lies to the south and southwest. Alaska is by far the largest U.S. state by area, comprising more total area than the next three largest states (Texas, California, and Montana) combined. It represents the seventh-largest subnational division in the world. It is the third-least populous and the most sparsely populated state, but by far the continent's most populous territory located mostly north of the 60th parallel, with ...

Plants Described In 1899
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...
