Degelia Plumbea
''Degelia plumbea'' (also called blue felt lichen) is a species of grey to blue-black or brown foliose lichen in the genus ''Degelia''. It mostly grows on trees in undisturbed woodlands but occasionally on coastal rocks. It is found widely in Britain and western Ireland as well as in America and Canada, as it grows in maritime Atlantic climates. ''D. plumbea'' is highly sensitive to acid rain and climatic changes. ''Degelia cyanoloma ''Degelia cyanoloma'' is a species of blue-grey to lead-grey foliose lichen in the genus Degelia. It mostly grows on mossy trees in undisturbed woodlands. It is found in the Scottish Highlands, western Ireland and Norway (as well as less prolifi ...'' was previously thought to be a variant of ''D. plumbea''.

Brittany
Brittany (; french: link=no, Bretagne ; br, Breizh, or ; Gallo language, Gallo: ''Bertaèyn'' ) is a peninsula, Historical region, historical country and cultural area in the west of modern France, covering the western part of what was known as Armorica during the period of Roman occupation. It became an Kingdom of Brittany, independent kingdom and then a Duchy of Brittany, duchy before being Union of Brittany and France, united with the Kingdom of France in 1532 as a provinces of France, province governed as a separate nation under the crown. Brittany has also been referred to as Little Britain (as opposed to Great Britain, with which it shares an etymology). It is bordered by the English Channel to the north, Normandy to the northeast, eastern Pays de la Loire to the southeast, the Bay of Biscay to the south, and the Celtic Sea and the Atlantic Ocean to the west. Its land area is 34,023 km2 . Brittany is the site of some of the world's oldest standing architecture, ho ...

USDA
The United States Department of Agriculture (USDA) is the federal executive department responsible for developing and executing federal laws related to farming, forestry, rural economic development, and food. It aims to meet the needs of commercial farming and livestock food production, promotes agricultural trade and production, works to assure food safety, protects natural resources, fosters rural communities and works to end hunger in the United States and internationally. It is headed by the Secretary of Agriculture, who reports directly to the President of the United States and is a member of the president's Cabinet. The current secretary is Tom Vilsack, who has served since February 24, 2021. Approximately 80% of the USDA's $141 billion budget goes to the Food and Nutrition Service (FNS) program. The largest component of the FNS budget is the Supplemental Nutrition Assistance Program (formerly known as the Food Stamp program), which is the cornerstone of USDA's ...

Peltigerales
Peltigerales is an order of lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. The taxonomy of the group has seen numerous changes; it was formerly often treated as a suborder of the order Lecanorales. It contains two suborders, eight families and about 45 genera such as ''Lobaria'' and ''Peltigera''. The fungi form lichens in a symbiotic relationship with one or two photosynthetic partners which may be a cyanobacterium such as ''Nostoc'' or a green alga such as '' Coccomyxa''. The majority of species contain just a cyanobacterium, a smaller number have both a cyanobacterium and a green alga while only a few species have just a green alga. The thallus of the lichen may be foliose (leafy), subfruticose (somewhat shrubby) or granular-squamulose (scaly). The thallus attaches to a surface by means of small root-like rhizines. In some species, the thallus may vary in appearance depending on whether it contains a cyanobacterium or a green alga. Some ...

Acid Rain
Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH). Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average. The more acidic the acid rain is, the lower its pH is. Acid rain can have harmful effects on plants, aquatic animals, and infrastructure. Acid rain is caused by emissions of sulphur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. Acid rain has been shown to have adverse impacts on forests, freshwaters, soils, microbes, insects and aquatic life-forms. In ecosystems, persistent acid rain reduces tree bark durability, leaving flora more susceptible to environmental stressors such as drought, heat/cold and pest infestation. Acid rain is also capable of detrimenting soil composition by stripping it of nutrients such as ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N. Scientific explorations of the A ...

John Lightfoot (biologist)
The Reverend John Lightfoot (9 December 1735 – 20 February 1788) was an English parson-naturalist, spending much of his free time as a conchologist and botanist. He was a systematic and effective curator of the private museum of Margaret Bentinck, Duchess of Portland. He is best known for his ''Flora Scotica'' which pioneered the scientific study of the plants and fungi of Scotland. He was elected a Fellow of the Royal Society for his scientific work. Life and work Lightfoot was born in Newent, Gloucestershire.

Oceanic Climate
An oceanic climate, also known as a marine climate, is the humid temperate climate sub-type in Köppen classification ''Cfb'', typical of west coasts in higher middle latitudes of continents, generally featuring cool summers and mild winters (for their latitude), with a relatively narrow annual temperature range and few extremes of temperature. Oceanic climates can be found in both hemispheres generally between 45 and 63 latitude, most notably in northwestern Europe, northwestern America, as well as New Zealand. Precipitation Locations with oceanic climates tend to feature frequent cloudy conditions with precipitation, low hanging clouds, and frequent fronts and storms. Thunderstorms are normally few, since strong daytime heating and hot and cold air masses meet infrequently in the region. In most areas with an oceanic climate, precipitation comes in the form of rain for the majority of the year. However, some areas with this climate see some snowfall annually during winter. M ...
