Dicranum Scoparium
''Dicranum scoparium'', the broom forkmoss, is a species of dicranid moss, native to most of the northern hemisphere as well as Oceania Oceania (, , ) is a region, geographical region that includes Australasia, Melanesia, Micronesia, and Polynesia. Spanning the Eastern Hemisphere, Eastern and Western Hemisphere, Western hemispheres, Oceania is estimated to have a land area of .... It usually forms tufts or mats on soil in dry to moist forested areas. As with many types of moss Broom moss grows in clumps with Broom mosses as well as other mosses. It can be distinguished by its leaves, which strongly curve to one side. Description Broom forkmoss is usually robust and coarse, forming shiny tufts with woolly stems 2–8 cm high. The leaf midrib extends to the tip and usually has 4 ridges along its back. The leaves are 3.5–8 mm long, lance-shaped with a long, slender point, and strongly toothed along the upper third. Most leaves will be folded and curved to one s ...

Lake Superior Provincial Park
Lake Superior Provincial Park is one of the largest provincial parks in Ontario, covering about along the northeastern shores of Lake Superior between Sault Ste. Marie and Wawa in Algoma District in Northeastern Ontario, Canada. Ontario Highway 17 (at this point part of the Trans-Canada Highway) now runs through the park. When the park was established by Ontario in 1944, there was no road access. History Traces of ancient volcanic A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates a ... activity can be seen in rock outcrops near Red Rock Lake and several other sites. For more than 2000 years, this was long an area of occupation by various cultures of indigenous peoples. The oldest artifacts found here date to approximately 500 BC.

Dicranaceae
Dicranaceae is a family of haplolepideous mosses (Dicranidae) in class Bryopsida. Species within this family are dioicous Dioicy () is a sexual system where archegonia and antheridia are produced on separate gametophytes. It is one of the two main sexual systems in bryophytes. Both dioicous () and monoicous gametophytes produce gametes in gametangia by mitosis ra .... Genera in this family include '' Dicranum'', '' Dicranoloma'', and '' Mitrobryum''.

Oceania
Oceania (, , ) is a region, geographical region that includes Australasia, Melanesia, Micronesia, and Polynesia. Spanning the Eastern Hemisphere, Eastern and Western Hemisphere, Western hemispheres, Oceania is estimated to have a land area of and a population of around 44.5 million as of 2021. When compared with (and sometimes described as being one of) the continents, the region of Oceania is the smallest in land area and the list of continents and continental subregions by population, second least populated after Antarctica. Its major population centres are Sydney, Melbourne, Brisbane, Perth, Auckland, Adelaide, Honolulu, and Christchurch. Oceania has a diverse mix of economies from the developed country, highly developed and globally competitive market economy, financial markets of Australia, French Polynesia, Hawaii, Hawaii, New Caledonia, and New Zealand, which rank high in quality of life and Human Development Index, to the much least developed countries, less developed ...

Operculum (bryozoa)
In the bryozoan order Cheilostomatida, the operculum is a calcareous or chitinous lid-like structure that protects the opening through which the polypide protrudes. Many species have modified the operculum in specialized zooids (avicularia) to form a range of mandibles (probably for defense) or hair-like setae (probably for cleaning, or in some unattached species, such as '' Selenaria'', for locomotion). The cyclostome family Eleidae also convergently evolved an opercular structure during the Early Cretaceous to Paleocene The Paleocene, ( ) or Palaeocene, is a geological epoch that lasted from about 66 to 56 million years ago (mya). It is the first epoch of the Paleogene Period in the modern Cenozoic Era. The name is a combination of the Ancient Greek ''pal ....Taylor, P.D. 1994.

Rhizoid
Rhizoids are protuberances that extend from the lower epidermal cells of bryophytes and algae. They are similar in structure and function to the root hairs of vascular land plants. Similar structures are formed by some fungi. Rhizoids may be unicellular or multicellular. Evolutionary development Plants originated in aquatic environments and gradually migrated to land during their long course of evolution. In water or near it, plants could absorb water from their surroundings, with no need for any special absorbing organ or tissue. Additionally, in the primitive states of plant development, tissue differentiation and division of labor was minimal, thus specialized water absorbing tissue was not required. The development of specialized tissues to absorb water efficiently and anchor themselves to the ground enabled the spread of plants to the land. Description Rhizoids absorb water mainly by capillary action, in which water moves up between threads of rhizoids and not through ea ...

Flora Of The Great Lakes Region (North America)
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ...
