GLEO CAPSA WHAT????
Cyanobacteria a.k.a. Gleo Capsamagma = Black Roof Streaks
Cyanobacteria are photosynthetic organisms; like plants they trap the energy of the sun (autotrophically) to use in their own metabolism and give off
oxygen in the process. In order to achieve this they have their own chlorophyll called 'Chlorophyll a'.
Cyanobacteria are often called blue-green algae, though they are not all a blue-green color and they are not algae at all. The green coloration comes from
their chlorophyll while the blue comes from a photosynthetic accessory pigment called phycocyanin. Some cyanobacteria have a different accessory
pigment called phycoerythrin. This is red and combined with the green chlorophyll gives these cyanobacteria a brown color.
Cyanobacteria can be found in many habitats; soil, on rocks, in fresh water and salt water. They can also be found in the desert where they remain
dormant for most of the time, taking advantage of the occasional rains. In aquatic environments they often form thick mats. Like many bacteria they have a
higher tolerance of heat and low pH values than green plants, so they are often the main autotrophs in hot springs.
Finally, a number of cyanobacteria have formed symbioses with other organisms such as liverworts, ferns and cycads,however, their best known symbiosis
is with various fungi to form numerous lichens.
Cyanobacteria were probably the first organisms on earth to release oxygen into the atmosphere, in this way they would have played a major role in
making the planet suitable for animals like ourselves. Important genera include Stigonema,Nostoc, Anabaena, Chlorobium and Hapalosiphan.

Lichen has a root like appendage (rhizines) that creates pressure against the
granules creating damage by dislodging the granules affixed to the shingle matting.
They do excrete acids and chemicals to break down the surfaces they inhabit.
The lichen is the white resembling reef coral and the black coating is the algae.
These two live together to create a perfect ecosystem up on the roof tops of
thousands of roofs.

Lichen
A lichen is a symbiosis between a fungus and a photobiont. The photobiont can be an alga (mostly green) and/or a cyanobacteria. About 10% of the
lichens are considered to be cyanolichens – that is lichens that have cyanobacteria as the primary photobiont In either case, the photobiont performs
photosynthesis providing nourishment for the fungal partner.
The fungal partner in turn provides a habitat for the photobiont that includes moisture and proper exposure to light. The kind of surfaces lichens grow on
is multiple such as,bark, wood, rocks, mosses, soil, dead vegetation, leaves,pinecones, manmade objects, etc.
Most lichens are particular as to the type of substrate they live on, with some species being more of a “generalist” than others. Some lichens are found
only on a specific type of rock (calcareous, siliceous,sandstone, granite, etc.) or the bark of a certain type of tree (smooth bark deciduous, conifer, oak,
chaparral shrubs, etc.). Still others use manmade objects like wooden fences, barns, metal junk, sidewalks, mortar, roofing shingles, etc. as substrates. In
the tropics many lichens are found growing on leaves. Many experts think lichens were some of the first organisms to colonize land surfaces on the young
earth. The root-like organs of lichens are called rhizines. The rhizines penetrate rocks and aid decomposition. Lichens also produce acids and
other chemicals that break down rocks and other materials. The materials are also used to support growth of the lichens.
In a sense, the rocks are long-term or very-slow-release fertilizers. The rock decomposition minerals start the formation of soils. As lichens die they add
to the organic material to the soil.

Mosses
Mosses have rootlike appendages called rhizoids, which anchor the plant in shallow soil and diffuse water and minerals
through their cells, less efficiently than real roots do, but well enough to sustain a fairly complex plant. The mosses evolved to
use the small amounts of soil created by the lichens, and then helped build up a thicker layer by catching windblown dirt in
their interlocking system of rootlets and upraised stems. The accumulation of soil made possible the evolution of higher
plants with real roots. These dirtbuilding processes continue today, right under our noses.

"Living organisms may contribute to mechanical weathering,as well as chemical weathering. Lichens and mosses grow on
essentially bare rock surfaces and create a more humid chemical microenvironment. The attachment of these organisms to
the rock surface enhances physical as well as chemical breakdown of the surface microlayer of the rock.
On a larger scale seedlings sprouting in a crevice and plant roots exert physical pressure as well as providing a pathway for
water and chemical infiltration."
