Two commercial formulations of Beauveria bassiana (Balsamo-Crivelli) Vuillemin were applied to residential sites in Old Lyme, CT, for the control of nymphs of the blacklegged tick, Ixodes scapularis, in 1999 and 2000. The pyrethroid bifenthrin was applied to other premises for comparison with B. bassiana. A wood chip barrier was installed and maintained at six of the treated properties. In 1999, control of I. scapularis nymphs ranged from 74.5 to 83.0% on lawns without wood chips and from 88.9 to 90% on lawns with wood chip barriers. As a control check, no ticks (n= 23) collected …

Potential For Stable Flies And House Flies (Diptera: Muscidae) To Transmit Rift Valley Fever Virus1, Michael J. Turell, David J. Dohm, Christopher J. Geden, Jerome A. Hogsette, Kenneth Linthicum
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Rift Valley fever (RVF), a disease of ruminants and humans, has been responsible for large outbreaks in Africa that have resulted in hundreds of thousands of human infections and major economic disruption due to loss of livestock and to trade restrictions. As indicated by the rapid spread of West Nile viral activity across North America since its discovery in 1999 and the rapid and widespread movement of chikungunya virus from Africa throughout the Indian Ocean Islands to Asia and Europe, an introduced exotic arbovirus can be rapidly and widely established across wide geographical regions. Although RVF virus (RVFV) is normally …

Liana Host Preference And Implications For Deciduous Forest Regeneration, 2010 Eastern Illinois University
Liana Host Preference And Implications For Deciduous Forest Regeneration, Laura M. Ladwig, Scott J. Meiners
Faculty Research & Creative Activity
Lianas have the potential to shape forest communities and alter forest regeneration. However, impacts of lianas on forest regeneration, particularly in temperate forests, are largely unstudied. To understand potential liana impacts on the community we need to first know the location and intensity of liana burdens on host trees. We examined liana-tree host references within a series of young regenerating deciduous forests in the Piedmont region of New Jersey, USA. Established trees ($ 5 cm dbh) and the lianas associated with each tree were surveyed in 2008. The five most abundant liana species were Celastrus orbiculatus, Lonicera japonica, Parthenocissus quinquefolia, …
Relative Allelopathic Potential Of Invasive Plant Species In A Young Disturbed Woodland, 2010 Eastern Illinois University
Relative Allelopathic Potential Of Invasive Plant Species In A Young Disturbed Woodland, Nikki Pisula, Scott J. Meiners
Faculty Research & Creative Activity
Invasive plant species are often more successful within introduced areas when compared to their natural ranges. Allelopathy has been suggested as a potential mechanism for this success because invasive plants frequently establish monocultures and may produce allelochemicals evolutionarily novel to the recipient community. However, species are typically tested in isolation making the relative strength of allelopathy difficult to assess. We conducted laboratory bioassays for 10 co-occurring non-native species to determine the relative strength of their allelopathic potential. These species represented a suite of successful invaders within a young forest and were from a variety of plant life forms: trees, lianas, …
Spatiotemporal Dynamics Of Lianas During 50 Years Of Succession To Temperate Forest, 2010 Eastern Illinois University
Spatiotemporal Dynamics Of Lianas During 50 Years Of Succession To Temperate Forest, Laura Ladwig, Scott J. Meiners
Faculty Research & Creative Activity
Although they are important components of forest communities, the general ecology and spatiotemporal patterns of temperate lianas during forest regeneration are largely unknown. The dependence of lianas on other plants for physical support makes them a potentially important driver of community dynamics. We examined 50 years of vegetation data from an old-field succession study to determine the dynamics and community controls on liana expansion within the Piedmont region of New Jersey, USA. Four lianas, Lonicera japonica, Parthenocissus quinquefolia, Toxicodendron radicans, and Vitis spp., occurred in enough abundance for detailed analyses. In general, liana cover peaked during mid-succession (20–30 years post-abandonment) …

Allelopathic Effects Of Goldenrod Species On Turnover In Successional Communities, 2010 Eastern Illinois University
Allelopathic Effects Of Goldenrod Species On Turnover In Successional Communities, Nikki Pisula, Scott Meiners
Faculty Research & Creative Activity
While goldenrod species are often found to be allelopathic in laboratory settings, its importance in controlling plant community dynamics has been much more difficult to assess. We designed a study to determine whether allelopathy is related to the success of goldenrods in abandoned agricultural land. To accomplish this, we conducted laboratory bioassays for six co-occurring goldenrod species and compared these results to the cover and impacts of these species in the field. We determined the germination responses of two target species to a gradient of leaf extract concentrations to assess the allelopathic potential of these goldenrods. We also used long-term …

Pollen Interception By Linyphiid Spiders In A Corn Agroecosystem: Implications For Dietary Diversification And Risk-Assessment, 2010 University of Nebraska-Lincoln
Pollen Interception By Linyphiid Spiders In A Corn Agroecosystem: Implications For Dietary Diversification And Risk-Assessment, Julie A. Peterson, Susan Romero, James D. Harwood
West Central Research and Extension Center, North Platte
Dietary diversification, including consumption of plant tissues such as pollen, can enhance the fecundity of generalist predators, resulting in improved control of pest prey. Supplemental pollen feeding has been observed in many natural enemies, including sheet-web spiders (Araneae: Linyphiidae), which represent a major component of food webs in agroecosystems. Their horizontal, ground-based webs have the potential to intercept pollen grains during anthesis of crop plants, providing the opportunity for consumption of pollen to occur. In laboratory feeding trials, Frontinella communis and Tennesseellum formicum (Araneae: Linyphiidae) readily fed on pollen grains dusted on their webs, with 82 and 92% of spiders …

Overseeding Unimproved Warm-Season Pasture With Cool- And Warm-Season Legumes To Enhance Forage Productivity, 2010 Langston University
Overseeding Unimproved Warm-Season Pasture With Cool- And Warm-Season Legumes To Enhance Forage Productivity, P. W. Bartholomew, R. D. Williams
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Overseeding forage legumes into existing warm-season pasture may help to reduce cool-season forage deficit on small and resource-limited small farms in the southern Great Plains of the United States. Unimproved warm-season grass pastures were overseeded with Korean lespedeza (Lespedeza stipulacea Maxim) were not overseeded with summer legume. These same plots were subsequently overseeded with hairy vetch (Vicia villosa Roth), crownvetch (Coronilla varia L.), black medic (Medicago lupulina L.) or ladino white clover (Trifolium repens L.) or, not overseeded with cool-season legume. Including lespedeza in a forage mixture increased total forage yield by an average of …

Land Use And Climatic Factors Structure Regional Patterns In Soil Microbialcommunities, 2010 John Carroll University
Land Use And Climatic Factors Structure Regional Patterns In Soil Microbialcommunities, Rebecca E. Drenovsky, Kerri L. Steenworth, Louise E. Jackson, Kate M. Scow
Biology
Aim Although patterns are emerging for macroorganisms, we have limited under- standing of the factors determining soil microbial community composition and productivity at large spatial extents. The overall objective of this study was to discern the drivers of microbial community composition at the extent of biogeo- graphical provinces and regions. We hypothesized that factors associated with land use and climate would drive soil microbial community composition and biomass. Location Great Basin Province, Desert Province and California Floristic Province, California, USA. Methods Using phospholipid fatty acid analysis, we compared microbial com- munities across eight land-use types sampled throughout the State of …
Plant Community And Tissue Chemistry Responses To Fertilizer And Litter Nutrient Manipulations In A Temperate Grassland, 2010 John Carroll University
Plant Community And Tissue Chemistry Responses To Fertilizer And Litter Nutrient Manipulations In A Temperate Grassland, Rebecca E. Drenovsky, Jean J. Pan, Brittany Widner, Deborah Ammerman
Biology
Human-mediated nutrient amendments have widespread effects on plant communities. One of the major consequences has been the loss of species diversity under increased nutrient inputs. The loss of species can be functional group dependent with certain functional groups being more prone to decline than others. We present results from the sixth year of a long-term fertilization and litter manipulation study in an old-field grassland. We measured plant tissue chemistry (C:N ratio) to understand the role of plant physiological responses in the increase or decline of functional groups under nutrient manipulations. Fertilized plots had significantly more total aboveground biomass and live …
