Effects of Local Conspecific Density on Reproductive Success in Penstemon Digitalis and Hesperis Matronalis Mitchell, Randall J.; Ankeny, Daniel P. We investigated the effects of plant density on reproductive success for two insect-pollinated plant species—the native North American wildflower Penstemon digitalis (Foxglove-leaved Penstemon), and the showy introduced weed Hesperis matronalis (Dame's Rocket). We found no indication that local density (within 3.0 m) affected reproductive success (seeds per fruit, proportion fruit set, total seeds per plant) for either species. Penstemon digitalis suffered heavy fruit predation from micro-lepidopterans, and such damage tended non-significantly to increase with density. We discuss the reasons for our results, and suggest that an understanding of those causes is important for conservation. Author Institution: Department of Biology, University of Akron

The Relationship Between Patterns in Flying Adult Insect Assemblages and Vegetation Structure in Wetlands of Ohio and Texas Garono, Ralph J.; Kooser, J.G. The success of compensatory wetland replacement is frequently judged on the basis of percent vegetation cover. Measuring percent cover of wetland species, or the survival of planted species, especially only one or two years after construction seems tautological. Aquatic insects have been used for many years as indicators of ecosystem integrity and may be useful as an integrative wetland assessment tool. This study was initiated to determine if adult insect assemblages could be used to differentiate between wetlands and uplands, and to identify site characteristics, especially vegetation, related to patterns in insect assemblages. We collected adult insect assemblages using light traps at wetlands in northeastern Ohio and southeastern Texas. We also measured properties of wetland vegetation structure and composition around the light traps and performed indirect gradient analysis. We found that ordinations of flying nocturnal insect assemblages generally separated upland from wetland sites and that insect ordination patterns were related to vegetation density and predominant vegetation growth forms such as vines, herbs, shrubs and trees.

Monitoring Southern Flying Squirrel Populations with Nest Boxes Althoff, Donald P.; Althoff, Peggy S. Evaluating the practicality, economic, and sampling efficiency of potential monitoring programs is a first step in validation. Thus, we established a system of nest boxes in southeast Ohio to evaluate the feasibility of using a system of nest boxes to monitor changes in southern flying squirrel (Glaucomys volans) populations. We recorded the time of box placement until first usage and types of use by flying squirrels as an indicator of presence as well as nest box occupancy trends on a month-to-month basis to assess usage patterns and productivity. Using monitoring results from 4 years, we evaluated alternative survey sampling techniques for occupancy and determined sample sizes necessary to estimate occupancy within specified relative bounds. We also studied the cost of establishing a nest box system and monitoring nest box use. At low nest box occupancy (9.4%), sample size necessary to monitor trend would be extreme (431 boxes for 30% relative bound), but sample size is not restrictive when occupancy rates exceed 17% (211 boxes to achieve 20% relative bound). Monitoring combined spring and summer litter sizes in November or December as a measure of recruitment would require a smaller effort to achieve a tighter relative bound (10%). Assumptions relating these demographic parameters to habitat change or disturbance still must be tested before the systematic placement of nest boxes can be considered the optimum approach to monitor southern flying squirrel response as measured by changes in population density or recruitment.
