Temporal Variation In Community Composition, Pigmentation, And Fv/Fm Of Desert Cyanobacterial Soil Crusts, M. A. Bowker, S. C. Reed, J. Belnap, S. L. Phillips Jan 2002

Temporal Variation In Community Composition, Pigmentation, And Fv/Fm Of Desert Cyanobacterial Soil Crusts, M. A. Bowker, S. C. Reed, J. Belnap, S. L. Phillips

Canyonlands Research Bibliography

Summers on the Colorado Plateau (USA) are typified by harsh conditions such as high temperatures, brief soil hydration periods, and high UV and visible radiation. We investigated whether community composition, physiological status, and pigmentation might vary in biological soil crusts as a result of such conditions. Representative surface cores were sampled at the ENE, WSW, and top microaspects of 20 individual soil crust pedicels at a single site in Canyonlands National Park, Utah, in spring and fall of 1999. Frequency of cyanobacterial taxa, pigment concentrations, and dark adapted quantum yield (Fv/Fm) were measured for each core. The frequency of major …

Safeguarding Species, Languages, And Cultures In The Time Of Diversity Loss: From The Colorado Plateau To Global Hotspots, Gary Paul Nabhan, Patrick Pynes, Tony Joe Jan 2002

Safeguarding Species, Languages, And Cultures In The Time Of Diversity Loss: From The Colorado Plateau To Global Hotspots, Gary Paul Nabhan, Patrick Pynes, Tony Joe

Canyonlands Research Bibliography

Hotspots of biodiversity have become priority areas for land conservation initiatives, oftentimes without recognition that these areas are hotspots of cultural diversity as well. Using the Colorado Plateau ecoregion as a case study, this inquiry (1) outlines the broad geographic patterns of biological diversity and ethnolinguistic diversity within this ecoregion; (2) discusses why these two kinds of diversity are often influenced by the same geographic and historic factors; and (3) suggests what can be done to integrate traditional ecological knowledge of indigenous peoples into multicultural conservation collaborations.

2002 File Geodatabase Containing Photo Point Locations, Aerial Photos, And Flight Maps, City Of Tampa Department Of Sanitary Sewers Bay Study Group, Pete Reehling, Richard Mckenzie Jan 2002

2002 File Geodatabase Containing Photo Point Locations, Aerial Photos, And Flight Maps, City Of Tampa Department Of Sanitary Sewers Bay Study Group, Pete Reehling, Richard Mckenzie

Data Sets

The Bay Study Group was created by the City of Tampa in 1976 to monitor the effects of pollution abatement that occurred in Hillsborough Bay when the city’s wastewater treatment plant was upgraded from primary to advanced treatment in 1979. The Bay Study Group documented a remarkable restoration of water quality parameters and biological indicators in Hillsborough Bay from the mid 1980s until 2009, when it was disbanded. This zip Geodatabase file contains the photo point locations, aerial photos, and flight maps for the year 2002.
