What are reindeer lichens?
Reindeer Lichens grow in northern temperate forests, boreal forests, and even in the tundra. They are highly branched, fruticose lichens that are a primary food source for reindeer (also called caribou in North America). These lichens are sometimes called “Reindeer Moss,” even though they are lichens and not moss.
Is reindeer moss the same as reindeer moss?
These lichens are sometimes called “Reindeer Moss,” even though they are lichens and not moss. Reindeer Lichens, like other Cladonia species, form two types of structures. Initially, the lichen grows flat along the ground and produces small, scale-like protrusions ( foliose morphology).
Does reindeer lichen cause pimples?
Yellow reindeer lichen contains usnic acid that can induce rash, itch and rarely formation of pimples, when it comes in contact with skin (condition known as lichen dermatitis). Reindeer lichen grows slowly and produces one branch per year.
How fast does reindeer lichen grow?
Reindeer lichen, like many lichens, is slow growing (3–11 mm per year) and may take decades to return once overgrazed, burned, trampled, or otherwise consumed. A similar-looking species, also known by the common name "reindeer lichen", is Cladonia portentosa .
Is the lichen a producer?
The Lichen Is a Decomposer Lichens release chemicals that work to break down rocks, creating more soil. In the tundra, there is very little plant life to do this work and lichens are of critical importance. Though the lichen is a decomposer, it is not a parasite.
Is reindeer lichen a decomposer?
Surprisingly enough, you can buy Reindeer Lichen commercially. I have seen it for sell on Amazon.com. it is often used in floral arrangements. Lichens, in general, are important as decomposers.
Is lichen a plant or Decomposer?
Lichens are often decomposers, fulfilling an essential role in an ecosystem of breaking down dead (and sometimes living) things. Most lichens grow extremely slowly – less than 1 millimeter per year! There are three forms of lichen – crustose, foliose and fruticose.
What does reindeer moss produce?
Reindeer moss is a lichen and therefore, is a combination of fungus and alga. They reproduce by forming a symbiotic (close) relationship, releasing spores that are blown by the wind which produces a new plant. First, the green plant (gametophyte) produces male and female sex cells (gametes) which later fuse together.
Is reindeer moss a decomposer?
They usually provide for themselves as parasites or decomposers. In the case of lichens they are in a symbiotic relationship to algae. The fungus gets sugars ,vitamins, and nitrogenous compounds from the algae. The algae makes these compounds through the process of photosynthesis.
Is caribou moss a producer?
Another Arctic producer species is Caribou moss, a grey-green moss that grows on rocks and other surfaces to about pine to two inches high. The diamond leaf willow is a shrub like producer, as is the Labrador tea plant.
Do lichens photosynthesis?
Photosynthesis in lichens is intimately linked to the photosynthetic capacities of the photobiont, i.e. autotrophic algae and cyanobacteria, that form the lichen association together with a fungal partner. Lichen photosynthesis in nature is also affected by a complex mixture of internal and external factors.
Is moss a producer?
Like all photosynthetic organisms, mosses are primary producers that build biomass through photosynthesis. They enrich ecosystems with organic matter, forming the basis of the food chain.
Is lichen a plant or fungus?
Lichens are bizarre organisms and no two are alike. Lichens are a complex life form that is a symbiotic partnership of two separate organisms, a fungus and an alga. The dominant partner is the fungus, which gives the lichen the majority of its characteristics, from its thallus shape to its fruiting bodies.
What is reindeer lichen good for?
Medicinal uses: Lichen is rich in vitamins A and B. Native Americans make a tea from the lichen, and use it to treat diarrhoea. It is also used as a laxative, a cough suppressant, to assist blood formation and to treat loss of appetite, gastritis, inflammation of the mouth, the pharynx and the intestines.
What type of lichen is reindeer moss?

Where is reindeer lichen found?
reindeer lichen, ( Cladonia rangiferina ), also called reindeer moss, a fruticose (bushy, branched) lichen found in great abundance in Arctic lands. The lichen covers immense areas in northern tundra and taiga ecosystems and serves as pasture for reindeer, moose, caribou, and musk oxen. In Scandinavia it has been used in the manufacture of alcohol, but difficulties in obtaining reindeer lichen arise because of its slow growth rate (3 to 5 mm [0.12 to 0.2 inch] per year). The name is also applied to the related lichen Cladonia portentosa. See also Cladonia.

What type of soil does a reindeer lichen prefer?
It prefers well-drained, sandy, usually acidic soils and areas that provide partial shade. Reindeer lichen occasionally grows on the surface of rocks and logs. Number of reindeer lichen in the wild is dropping due to wildfires, overgrazing and pollution of the air.
How tall is reindeer lichen?

Reindeer lichen produces hollow, branch-like structures with cottony surface. They can be whitish-green, yellowish-green or grayish-white, depending on the species.
Can humans digest reindeer lichen?
Indigenous people from the circumpolar areas sometimes consume parti ally digested reindeer lichen obtained from the stomach of caribou (humans cannot digest and obtain nutrients from the fresh reindeer lichen).
How do reindeer lichens reproduce?
Reindeer lichens swing both ways: they can reproduce sexually via spores, or they can asexually clone themselves. When fungi reproduce sexually, they send out root-like structures toward a neighboring fungus and exchange genetic information when they touch. They then release spores, single cells containing genetic material, which travel on the wind and disperse. When they land, they start growing and produce a new baby fungus that's genetically distinct from its parents. In asexual clonal reproduction, on the other hand, a piece of the entire lichen (fungus and alga), called the thallus, is pinched off and regrows into a whole organism that's genetically identical to its parent.
What is lichen made of?
But lichens present an extra challenge in this process, since they're made up of a fungus and an alga (or a kind of bacteria that performs photosynthesis) living together. "That means that all the DNA is mixed up together, we get one pool that contains fungal DNA and algal DNA," says Grewe.
How do lichens affect the ecosystem?
Lichens can reveal a lot about how wildfires affect ecosystems. "Wildfire is the most significant disturbance in the world's northernmost forests, and it plays a major role in determining the distribution and composition of plant communities," says Alonso-García. "In Eastern North America, four successional vegetation stages are generally identified after a fire. During the first stage, crustose lichens and mosses colonize the burned surface. Subsequently, the soil is covered by cup and horn lichens. The landscape remains mostly uniform for around 20 years until the arrival of fruticose lichens which replace the previous vegetation. Cladonia stellaris arrives the last one, usually three or four decades after fire." By studying genetic variations in reindeer lichens, the researchers hoped to learn how lichens recolonize an area after a fire.
What is the term for a piece of a lichen that is pinched off and regrows into?
In asexual clonal reproduction, on the other hand, a piece of the entire lichen (fungus and alga), called the thallus, is pinched off and regrows into a whole organism that's genetically identical to its parent. The two reproductive methods have different advantages.

Do lichens grow after fire?
That was counterintuitive -- the thought had been that the little cloned lichen bits would be destroyed in a fire, and that the repopulation of lichens would be growing from spores that arrived on the wind from other areas. "Regarding the genetic diversity of the species after fires, we found no differences along four stages of the succession. This was also astonishing because time since the last fire increases the probability that clonal fragments successfully reached the sites, enhancing genetic diversity," says Alonso-García.
Do reindeer lichens move nutrients?
They're a major part of reindeer diets, hence the name, and the forest depends on them to move nutrients through the ecosystem. They also, at least in parts of Quebec, are having a lot more sex than scientists expected. In a new study in the American Journal of Botany, researchers found that the reindeer lichens they examined have unexpected levels ...
