61. "inQuiry Almanack" - Quite Amazing! - December 1996 lichens any of various complex lower plants made up of an alga and a fungusgrowing together as a new organism. Purpose. I am investigating http://www.fi.edu/qa96/amy12/amy12.html

Note: In December, 1996, Amy outlined her experiment. Amy Begins Her Investigation (3800k) Quicktime Amy Introduces Her Investigation (93k) RealAudio lichens: any of various complex lower plants made up of an alga and a fungus growing together as a new organism Purpose I am investigating the effect of acid rain pollution on different samples of lichens, and as a result, seeing if these lichens can be used as bioindicators. I will do this using samples of crustose, foliose, and fruticose lichens. crustose - crustlike, flaky foliose - leaflike, papery thin fruticose-pendant - a variety of fruticose fruticose - stalked, branchlike Predictions I feel that out of the three types of lichens, the fruticose sample will be most susceptible to the acidic solution. This "beard lichen" is described as bushy and shrubby. Most commonly grown from trees, these lichens are known to grow where the air is clean and less polluted. I feel the foliose lichen sample will be the next most susceptible to the acidic solution. These lichens can be green, yellow, black, or orange and cling to rocks and trees. Foliose lichens are known to be able to survive in slightly polluted areas. The crustose lichen sample will be the least susceptible to the acidic solution. This type of lichen forms hard crusts on barks and rocks. They can survive in polluted areas and are the least developed lichen form. Procedure I will order two samples of lichen sets that include portions of crustose, foliose, and fruticose lichens priced at $10.25 per set.

Hood National Forests and the Columbia River Gorge National Scenic Area pooled resources to develop a unified approach for biomonitoring air quality using non-vascular plants. They wanted information which would be comparable across Forest boundaries and interface with other Forest, regional and national databases. The primary objectives of the program are to help Forests meet federal and agency responsibilities for the detection and description of air pollution impacts and the protection of Forest air resources. Secondary objectives are to improve our understanding of the ecological roles of non-vascular plants and to develop their potential as indicators of forest health, stability and biodiversity.

66. Looking At Lichens Looking at lichens. by Doug Ladd. lichens grow throughout Missouri and area major contributor to the mosaic of colors in our natural landscape. http://www.conservation.state.mo.us/conmag/1998/10/2.html

Looking at Lichens by Doug Ladd Part algae, part fungi, these organisms merit more than a casual glance. Almost everyone is familiar with the term lichen (pronounced "like-in"), but few people know much about these small plantlike organisms. Lichens grow throughout Missouri and are a major contributor to the mosaic of colors in our natural landscape. They grow on all types of rocks and trees in a variety of habitats, and they are an important component of healthy habitats. British Solders (Caladonia cristatella) Cedar lichen (Vulpicidia viridis) Pyxie cups (Cladonia grayi) Wrinkled shield lichen (Flavoparmelia caperata) Reindeer lichen (Cladina subtenuis) Cliff wafer (Dermatocarpon miniatum) Lemon lichen (Candelaria concolor) Grey star lichen (Physcia stellaris) Rough shield lichen (Punctelia rudecta) Gold eye lichen (Teloschistes) Old man's beard (Usnea strigosa) Jewel lichen (Caloplaca feracissima) Boulder lichen (Xanthoparmelia cumberlandia) lichen grasshopper colored like boulder lichen. Lichen grasshoppers are almost impossible to find when resting on patches of boulder lichen. Lichens often are lumped with mosses or other small plants, although they have little in common except size and habitat because lichens have no roots, stems or leaves. Unlike most animals and leafy plants, a lichen is a fusion of two unrelated organisms. Every lichen is a combination of a fungus and algae or algaelike bacteria. Bread mold, morel mushrooms or the toadstools that sometime grow in our lawns are some familiar fungi. Algae are most familiar to us as the green scum on ponds and other slow-flowing waters.

Products of Lichen research at the Smithsonian Institution include databases of lichen nomenclature and lichen specimen collections as well as many publications on the taxonomy and systematics of lichens. The work of Mason E. Hale produced a checklist of names in the Parmeliaceae. As part of an international project to improve the taxonomy and nomenclature of this family, Monographic Studies in the Cladoniaceae, a database of currently accepted species names in Cladoniaceae is being produced that will be linked to descriptions, illustrations, and maps (NSF-sponsored PEET Grant to Paula DePriest).

Lichen From Wikipedia, the free encyclopedia. Crustose and foliose lichens on a wall enlarge image Lichens are symbiotic organisms made up by the association of microscopic green algae or cyanobacteria and filamentous fungi . Lichens take the external shape of the fungal partner and hence are named based on the fungus. The lichen fungus is typically a member of the Ascomycota Basidiomycota . Some taxonomists place lichens in their own division ( Mycophycophyta ), but this ignores the fact that the components belong in separate lineages. Lichens live on various surfaces: forest soil, trees, rocks, and walls. They are often the first to settle in uninhabited places, constituting the sole vegetation in some extreme environments such as at high mountain elevations and at high latitudes. Some of them live in the tough conditions of deserts, and others survive on frozen soil of the arctic regions. Some lichens have the aspect of leaves ( foliose lichens); others cover the substratum like a crust ( crustose lichens); others adopt shrubby forms ( fruticose lichens); and there are gelatinous lichens (see lichen types below).

B.C. Ministry of Forests Forest Science Program Abstract for SRS08 The Lichens of British Columbia — Illustrated Keys Part 1 – Foliose and Squamulose Species Authors or Ministry Contacts: T. Goward, B. McCune, and D. Meidinger Branch: Research Subject: Botany Series: Special Report Series Other details: Published 1994, 181 pages. Funding for Internet version was provided by Forest Renewal BC Abstract Approximately 1100 species of lichens have been reported to occur in British Columbia (B.C.). Although this figure may appear impressive, lichens are among the most poorly documented elements of the province's macroscopic flora. Judging from the rate at which new species are being added to the lichen flora, it seems likely that hundreds of additional lichens await discovery in this province. Moreover, our understanding of the frequency status of the vast majority of species remains dolefully incomplete. To date, comprehensive lichen studies have been conducted in only two regions of the province: the Queen Charlotte Islands and southeast Vancouver Island. The macrolichen flora of Wells Gray Park is also reasonably well documented. Most of the remainder of the province has received scant attention. Important collections have been made in the regions indicated in Figure 1 ( In PDF file ), but most of these studies are unpublished and the specimens are now scattered in various herbaria.
