<br />Richter, B.D., and H.E. Richter, 2000, Prescribing Flood Regimes to Sustain Riparian
<br />Ecosystems along Meandering Rivers. Conservation BioloQV 14(5): 1467-1478. Valuable
<br />work on limitations of ecological succession from prevention of natural flow regimes, and
<br />prescription of flows needed to maintain diversity of riparian patch types by lateral channel
<br />migration Yampa River example..
<br />Ringelman, J.K., W.R. Eddelman andW.H. Miller, 1989, High plains reservoirs and sloughs. Pp.
<br />311-340 in Smith, L.M., R.L. Pederson, and R.M. Kaminski, Eds., Habitat Manaaement for
<br />Migratory and Winterina Waterfowl in North America. lubbock: Texas Tech University.
<br />Robertson, G.P., J.e. Brown, E.A. Chornesky, J.E. Frankenberger, P. Johnson, M. Lipson, J.A.
<br />Miranowski, ED. Owens, D. Pimentel, and L.A. Thrupp, 2004, Rethinking the Vision for
<br />Environmental Research in US Agriculture. BioScience 54(1): 61-65. Problem of lack of
<br />proact;ve research or vision for work to increase benefits from agriculture, rather than only
<br />reacting to problems; call for better uses of agricultural management choices.
<br />Saunders, D,A., R.J. Hobbs, and C.R. Margules, 1991, Biological Consequences of Ecosystem
<br />Fragmentation: A Review. Conservation Bioloav 5(1): 18-32. Covers the physical
<br />consequences of fragmentation especially well, such as edge effects, changes in
<br />microcJimates, etc. Note date, and compare with later work on landscape ecology and riverine
<br />applications, as developed from connectivity, isolation, and geographic or relative position and
<br />-matrix- or spatial context as described in this review.
<br />Schmitz, O.J., E. Post, C.E Bums, and K.M. Johnston, 2003, Ecosystem Responses to Global
<br />Climate Change: Moving Beyond Color Mapping. BioScience 53(12): 1199-1205. May be
<br />vel}' important because of demonstration of how traditional methods may provide misleading
<br />underestimation of climate variation impacts on resources.
<br />Seabfoom, E.W., and A.G. Van der Valk, 2003, Plant Diversity, Composition, and Invasion of
<br />ReSto.reel and Natural Prairie Pothole Wetlands: Implications for Restoration. Wetlands 23(1):
<br />1-12. Successful restoration requires more than hydrology; it may depend on connectivity to
<br />intact.vegetative communities. Restored wetlands had substantially different and less diverse
<br />communities, related by the study to dispersal limitation from intact areas.
<br />Semlitsch, R.D, and J.R. Bodie, 2003, Biolog.ical criteria for buffer zones around wetlands and
<br />riparian habitats for amphibians and reptiles. Conservation Biolooy 17(5): 1219-1228.
<br />Semlitsch, R.D., and J.R. Bodie, 1998, Are Smafl, Isolated Wetlands Expendable? Conservation
<br />Biolooy 12(5): 1129-1133. NoI -From an ecological perspective, small wetlands are crucial
<br />for maintaining regional biodiversity. - (P. 1131). For instance, larger wetlands may be less
<br />diverse in amphibians, other species, because .of presence of predators. Small wetlands are
<br />extremely valuable for plants, invertebrates, and many vertebrate species; -disappearance of .
<br />small wetlands will cause a dire reduction in the ecologicaf connectance..." (P. 1130).
<br />Number of populations matters, as sources for fe-colonization, metapopulation genetics, etc.
<br />Shutler, D., A. Mullie and R.G. Clark, 2000, Bird Communities of Prairie Uplands and Wetlands in
<br />Relation to Farming Practices in Saskatchewan. Conservation Bioloav 14(5): 1441-1451.
<br />Interesting for what it says and what it doesn't say... Says none of the farming practices
<br />compared had as much impact as just not farming at af!. They compared conventional farms,
<br />minimum tillage, organic and wild or restored sites. But, they did not compare small.field,
<br />hedgerow, shener-belted, and other practices sometimes associated with organic and
<br />horticultural or table vegetable farming. Still, supports idea that intact is better than later patch
<br />jobs.
<br />Skagen, S.K. and F. L.. Knopf, 1993, Toward Conservation of Midcontinental Shorebird
<br />Migrations. Conservation Bioloov 7(3): 533-541. Highly diverse group of migrants use
<br />dispersed wetlands; need large-scale Coordinated regional management to keep migratOty
<br />species viable.
<br />Smith,D.H., K. Klein, R. Bartholomay, I. Broner, G.E Cardon, andW.M. Frasier, with others,
<br />1996, Irriaation Water Conservation: ODoortunites and Limitations in Colorado. Fort Collins:
<br />Colorado State U., CO Water Res. Research Institute, CR No. 190.
<br />Snyder, W.D., and G.C. Miller, 1991, Changes in Plains Cottonwoods along the Arkansas and
<br />South Platte Rivers - Eastern Colorado. Prairie Naturalist 23(3): 165-176. Air photos
<br />analyzed for 31 to 36 year period. Important finding of deterioration of stands of cottonwoods,
<br />wolSe along Arkansas than along South Platte. This is related to channel width changes and
