Ms. R talks about the symbiotic relationships between cyanobacteria, fungi, and algae that forms cryptobiotic soil. The cryptobiotic crust holds water, stabilizes the sand and helps plants get started.

Biological Soil Crust
 
03:10
Biological Soil Crust is a living groundcover that forms the foundation of plant life in Canyonlands and the surrounding area. Join ranger Karen Henker and learn about this critical - and fragile - component of the high desert ecosystem. View and audio described version of this video: https://youtu.be/bsQUwcpNFl4

Cryptobiotic soil (Biological Soil Crust) and an insect on my lense...

This recording was made along the Confluence Overlook Trail in the Needles District of Canyonlands National Park in Utah. Biological soil crusts (also known as cryptogamic, microbiotic, microphytic, or cryptobiotic soils ) are communities of living organisms on the soil surface in arid- and semi-arid ecosystems. Cryptobiotic soils are found throughout the world with varying species composition and cover depending on topography, soil characteristics, climate, plant community, microhabitats, and disturbance regimes. Cryptobiotic soils crusts perform carbon fixation, nitrogen fixation, soil stabilization, alter soil albedo and water relations, and affect germination and nutrient levels in vascular plants. These soils are EASILY damaged by fire, recreational activity, grazing, and other disturbance and can require long time periods to recover composition and function so please avoid disturbing them! This recording was made in the Needles District of Canyonlands National Park in Utah. I believe this particular segment was somewhere along the Big Spring to Squaw Canyon loop trails. Anyway, Canyonlands National Park is located in southeastern Utah near the town of Moab. It's a colorful, fantastical landscape that's been eroded by the Colorado and Green Rivers into countless canyons, mesas, and buttes. Legislation creating the park was signed into law by President Lyndon Johnson on September 12, 1964. The park is divided into four districts: the Island in the Sky, the Needles, the Maze, and the rivers themselves. While these areas share a primitive desert atmosphere, each retains its own character. Author Edward Abbey ("Cactus Ed," whom I met privately with a few years before his passing...) was a frequent visitor who described Canyonlands as "...the most weird, wonderful, magical place on earth—there is nothing else like it anywhere."

Biocrust - Cryptogamic soil crust on the Colorado National Monument
 
01:03
Crytogramic soil (also known as soil crust or biocrust) is usually found in arid environments and can be made up of cyanobacteria, mosses and lichen. It's very fragile so I always avoid walking on it or making any kind of disturbance. I recorded this video on top of the plateau on the Liberty Cap trail in the Colorado National Monument - just a few kilometres from the Utah border and the city of Grand Junction, Colorado.

Are Toxins Escaping Our Lakes? UNH researchers study Cyanobacteria in aerosols
 
03:05
Lake closures in the hot summer months are often caused by Cyanobacteria blooms, also know as harmful algae blooms, which release toxins that may be linked to such diseases as ALS and Alzheimer’s. The University of New Hampshire’s Jim Haney and his team of researchers are looking at the possibility that these toxins are being breathed in via aerosols from the surface of the lake. This research was funded by the New Hampshire Agricultural Experiment Station, a research center of the UNH College of Life Sciences and Agriculture. Katie Langley ’15, student in the College of Life Sciences and Agriculture and the recipient of a Summer Undergraduate Research Fellowship (SURF) through UNH’s Hamel Center for Undergraduate Research, has been working closely with Professor Haney. Katie has spent her summer studying these aerosols to determine if toxins are in fact present and coming out of the lake, under what conditions they come out of the lake, and whether they are a potential source of toxins for people.
