Lichen

billions of people present in the world, humans began polluting their own planet, therefore causing many problems to other species of life. One such example reflected by this is the decreasing biodiversity of organisms within an environment, especially lichen. Scientists characterize environmental changes through the research of various organisms, due to their observable reactions toward change in their respective environment. Lichens, composite organisms consisting of a fungus and an algae or a cyanobacteria, act as bioindicators in revealing environmental changes, specifically ecological…

Lichen Sclerosus (LS) is a relativeley uncommon chronic inflammatory diseasethat often affects the external genitalia and perianal area. In 10% of cases there is also extragenital involvement. LS of the external genitalia has also been associated with squamous cell carcinoma of the penis and vulva. LS is 6-10 times more common in women where it often presents around menopause. In men LS is often seen in older men aged greater than 60 years. 15% of LS cases occur in children, mainly females,…

By Jonas Wilson, Ing. Med. Lichen striatus Lichen striatus (LS), also known as Blaschko linear acquired inflammatory skin eruption or linear lichenoid dermatosis, is a benign, rare and self-limiting inflammatory skin condition. It primarily affects children between the ages of 5 to 15 years. LS initially presents as pinkish-red or flesh colored spots that coalesce over a two-week period (or less) to form a dull and scaly linear band. Lesions associated with LS tend to occur more frequently…

Write a summary of the article using your own words. Lichens are evolutionarily deep symbioses of nature that are widespread and diversed. It is recently discovered that in addition to being composed of fungus and alga, as known by many, lichens are also composed of varying amounts and species of basidiomycete yeast. This discovery is made when Dr. Spribille and his colleagues analyze two species of lichen that are similar in genetics of fungus and alga but different in appearance,…

nitrate in precipitation (APIS). These adjustments mainly affect species that are customized to low nitrogen availability, like lichens mosses, and thus they are in danger of extinction. However, lichens are considered highly valued ecological indicators because of their sensitivity to a wide range of environmental stressors like air quality and climate change (Jovan 4). By identifying lichens that are sensitive, or tolerant, to the increase of nitrogen pollutants in an urbanized area, one can…

moths had to change a phenotype to adapt to their changing environment (Richardson, Urban, Bolnick et al. 2014). As for the selection and gene flow of how the peppered moths were able to survive in a changing environment are examples of how natural selection had to occur for the peppered to undergo a genetic mutation (Saccheri, Rousset, Watts et al. 2008). As well, the decrease of sulfur dioxide within the air reduces the phenotype within the moth to revert back to a lighter color (Grant, Cook,…

musk produced in the musk glands of males is a dark red brown granular powder with a strong smell.But in the months before and after the musk is pasty,white,and the smell is slight.They have long, curved canine teeth that project well below its lips.The males canines can grow 3 to 4 inches and the female’s canine teeth are shorter.The deers hind legs are a third longer than the deers forelegs.That is what the musk deer looks like. Secondly,I am going to tell you about its habitat and diet.It is…

opinion, I feel that Morgellons Disease sounds more like a mental illness. If sores and rashes are occurring on patients because of itching and the feeling of parasites on their skin but no parasites are being seen by professionals, then that is what leads me to believe it is more of a mental illness. Part 2: I choose to write about Lichen Planus. I choose to write about this disorder because I have never heard of it before and wanted to educate myself on something new. Some signs and symptoms…

“ Ptreygium will form if the matrix of the nail contains scar tissue causing the skin of the proximal nail fold to grow out with the skin of the nail bed giving it a triangular formation. Ptreygium occurs due to other skin and nail disorders such as lichen planus(“Lichen planus (LP) is a disease of the skin and/or mucous membranes that resembles lichen. The cause is unknown, but it is thought to be the result of an autoimmune process with an unknown initial trigger”), pemphigus…

the rooted poppy or the yellow poppy. It also attracts insects to it's center. Some Arctic poppies have white flowers instead of yellow. They are actually very tough, and their stems are hairy. It adapts to its habitat in many ways. It is covered in black hairs, and those hairs could be a sign warning animals not to come close to it. The white poppies adapted to the Arctic because they can camouflage with the white ice and snow. These poppies also adapted to growing on rocks, so much that the…
