Using Landscape History And Baseline Data In The Restoration Of A Midwestern Savanna, Andrew P. Rayburn, Annabel L. Major
Using Landscape History And Baseline Data In The Restoration Of A Midwestern Savanna, Andrew P. Rayburn, Annabel L. Major
Journal of the Iowa Academy of Science: JIAS
Over one hundred and fifty years of Euro-American settlement has dramatically altered Midwestern landscapes, resulting in the widespread conversion of native habitat. Numerous opportunities to conduct ecological restoration exist within the Midwest, with the potential to increase habitat and landscape heterogeneity, secure critical ecosystem services, and provide opportunities for research and education. Site history is an important consideration for most restoration projects, and multiple sources of historical data may be required to unravel the complicated history of intensively used Midwestern landscapes. The collection of baseline data is another significant component of most restoration projects, allowing for an evaluation of community …
Pre-Settlement Vegetation At Casey's Paha State Preserve, Iowa, Reid J. Leichty, Steven H. Emerman, Lyndon R. Hawkins, Michael J. Tiano
Pre-Settlement Vegetation At Casey's Paha State Preserve, Iowa, Reid J. Leichty, Steven H. Emerman, Lyndon R. Hawkins, Michael J. Tiano
Journal of the Iowa Academy of Science: JIAS
Paha are loess-capped ridges standing 10-30 m above the surrounding plain of the Iowan Surface. Although Iowa was almost entirely covered with prairie and wetlands just prior to Euro-American settlement, the paha are believed to have been forested based on soil types and on early vegetation maps. The objective of this study was to find evidence that paha were forested by measuring the δ13C value of humin, the fraction of soil organic matter that is insoluble in acid and base. Previous work has shown that humin retains the δ13C signature of vegetation on a 1000-year time scale, as opposed to …
Assessment Of Smallmouth Bass Populations In Iowa Interior Rivers, Andrew C. Jansen, Michael C. Quist, Jeff Kopaska
Assessment Of Smallmouth Bass Populations In Iowa Interior Rivers, Andrew C. Jansen, Michael C. Quist, Jeff Kopaska
Journal of the Iowa Academy of Science: JIAS
Smallmouth bass Micropterus dolomieu are a popular sport fish throughout North America and occupy an important ecological role as top predators in aquatic systems. Despite the importance of smallmouth bass, knowledge of their population structure and dynamics in Iowa interior rivers is limited. The objective of this study was to describe population dynamics (e.g., relative abundance, size and age structure, growth, mortality) of smallmouth bass in six Iowa rivers. Smallmouth bass were sampled from the Upper Iowa, Maquoketa, and Wapsipinicon rivers in northeast Iowa and the Des Moines, Iowa, and South Skunk rivers in central Iowa using electrofishing during the …
Observations On The Distribution And Status Of Western Sand Darter, Spotted Gar, And Skipjack Herring In Iowa Rivers, Travis E. Neebling, Michael C. Quist
Observations On The Distribution And Status Of Western Sand Darter, Spotted Gar, And Skipjack Herring In Iowa Rivers, Travis E. Neebling, Michael C. Quist
Journal of the Iowa Academy of Science: JIAS
This paper describes new records of western sand darter (Ammocrypta clara), spotted gar (Lepisosteus oculatus), and skipjack herring (Alosa chrysochloris) in Iowa's interior rivers. A western sand darter was collected from the Cedar River, Benton County, in 2007. Western sand darters are occasionally collected from the upper Mississippi River (UMR), but have not been sampled in interior rivers since 1958. Two spotted gar were collected from the Des Moines River, Polk and Wapello counties, in 2007. Two spotted gar were sampled from the UMR in 2000, but no spotted gar have been previously recorded from Iowa's interior rivers. A skipjack …
Ant Diversity In Two Southern Minnesota Tallgrass Prairie Restoration Sites, Pamela M. Kittelson, Monica Paulson Priebe, Phillip J. Graeve
Ant Diversity In Two Southern Minnesota Tallgrass Prairie Restoration Sites, Pamela M. Kittelson, Monica Paulson Priebe, Phillip J. Graeve
Journal of the Iowa Academy of Science: JIAS
There is little basic information about ant species richness and abundance in tall grass prairie restorations despite the importance of ants to plant community structure and function. We compared ant abundance and richness, vascular plant cover and richness, and soil compaction at two southern Minnesota grassland restoration sites, a prairie reconstruction and a prairie remnant undergoing rehabilitation. We collected a total of 3,523 ants from 12 different species. Plant species richness ranged from 45 in the prairie reconstruction to 95 in the remnant prairie. We found five more species of ants and significantly higher mean ant species richness per plot …
