In particular the number of heathland species with low dispersal ability was strongly related to area. Transplant experiments showed that some heathland species with low dispersal ability experienced reduced habitat quality in small habitats, whereas for others at least part of the unoccupied areas were of sufficient quality for successful reproduction. From the presence of occupied as well as unoccupied habitats and from knowledge on its possibilities for dispersal, it is inferred that Pterostichus lepidus lives in metapopulations with continuously and discontinuously occupied patches. Using allozymes, high levels of genetic variation were found in P.

  • Key Factors Affecting the Diversity of Sphagnum Cover Inhabitants with the Focus on Ground Beetle Assemblages in Central-Eastern European Peat Bogs
    COMMUNITY ECOLOGY 20(1): 45-52, 2019 1585-8553 © AKADÉMIAI KIADÓ, BUDAPEST DOI: 10.1556/168.2019.20.1.5 Key factors affecting the diversity of Sphagnum cover inhabitants with the focus on ground beetle assemblages in Central-Eastern European peat bogs G. Sushko Department of Ecology and Environmental Protection, Vitebsk State University P. M. Masherov, Moskovski Ave. 33, 21008 Vitebsk, Belarus. E-mail: [email protected] Keywords: Belarus, Carabidae, diversity, environmental factors, Sphagnum dwellers. Abstract. A key structural component in peat bog formation is Sphagnum spp., which determines very specific associated envi- ronmental conditions. The aim of this study was to characterise some of the key factors affecting the diversity, species richness and abundance of sphagnum inhabiting ground beetles and to examine the maintenance of stable populations of cold adapted specialised peat bog species. A total of 52 carabid species were recorded by pitfall traps along six main habitats, such as the lagg zone, pine bog, hollows, hummock open bog and dome. The results are characterised by a low diversity, which vary significantly among habitat types, and include a high abundance of a few carabid species. Among the variables influencing carabid species richness and abundance were plant cover, pH and the conductivity of the Sphagnum mat water. Vascular plant cover was a key factor shaping carabid beetle assemblages in the slope and the dome, while electric conductivity affected carabid beetle assem- blage in the lagg. Whereas, the water level was the most important factor for the hollows. At the same time, peat bog specialists showed low sensitivity to the gradient of the analysed variables.

A total of 819 carabids, representing 33 species and 19 genera, were collected. Saline produced significantly fewer captures than did acetic acid, ethanol, eth- ylene glycol, and propylene glycol, while distilled water produced significantly fewer captures than did acetic acid.

Yanahan University of Illinois at Urbana-Champaign During the Pleistocene, glacial advances left a small gap in the northwestern corner of Illinois, southwestern Wisconsin, and northeastern Iowa, which were never covered by the advancing Pleistocene glaciers (Taylor et al. 2009, p. 8, fig. 2.2). This is the Driftless Area – and it is one of Illinois’ most unique natural regions, comprising little more than 1% of the state. Illinois’ Driftless Area harbors more than 30 threatened or endangered plant species, and several unique habitat types. Among these habitats are talus, or scree, slopes, some of which retain ice throughout the year. The talus slopes that retain ice through the summer, and thus form a habitat which rarely exceeds 50 °F, even when the surrounding air temperature is in the 90’s °F, are known as “algific slopes.” While there are numerous examples of algific slopes in Iowa and Wisconsin, this habitat is very rare in Illinois (fewer than ten truly algific sites are known in the state).

  • Consequences of Omnivory and Alternative Food Resources on the Strength of Trophic Cascades
    ABSTRACT Title of Dissertation: CONSEQUENCES OF OMNIVORY AND ALTERNATIVE FOOD RESOURCES ON THE STRENGTH OF TROPHIC CASCADES Steven D. Frank, Doctor of Philosophy, 2007 Directed By: Associate Professor Paula M. Shrewsbury Department of Entomology & Professor Robert F. Denno Department of Entomology Omnivorous predators that feed on prey and plant resources are recognized as an important component of food webs but their impact on herbivore populations and trophic dynamics is unpredictable. Feeding on food items from multiple trophic levels increases the reticulate nature of food webs and the labile role of omnivores in promoting trophic cascades. Using carabid beetles in a corn agroecosystem, this research explored the interactive effects of predator guild (omnivore or carnivore) and the trophic origin of alternative food resources (seeds or fly pupae) on the control of herbivores (black cutworms) and plant survival. I demonstrated that the trophic guild and feeding performance of carabids can be predicted from their mandibular morphology. Carnivorous carabids, using mandibles with sharp points and a long shearing edge, kill and consume caterpillars more efficiently than omnivores that have mandibles with wide molar areas adapted for consuming prey and seeds. Omnivore preference for seeds and pupae further reduced their consumption of cutworms, which resulted in increased plant damage, ultimately dampening trophic cascades. In open field plots the abundance of omnivorous carabids and ants increased in response to seed but not pupae whereas neither subsidy affected the abundance of carnivorous predators. Pupae subsidies reduced predation of cutworms by carnivores and omnivores, consequently reducing seedling survival. However, in seed subsidized plots omnivorous predators switched from seeds to higher quality cutworm prey.

  • Coleoptera: Carabidae) Diversity
    VEGETATIVE COMMUNITIES AS INDICATORS OF GROUND BEETLE (COLEOPTERA: CARABIDAE) DIVERSITY BY ALAN D. YANAHAN THESIS Submitted in partial fulfillment of the requirements for the degree of Master of Science in Entomology in the Graduate College of the University of Illinois at Urbana-Champaign, 2013 Urbana, Illinois Master’s Committee: Dr. Steven J. Taylor, Chair, Director of Research Adjunct Assistant Professor Sam W. Heads Associate Professor Andrew V. Suarez ABSTRACT Formally assessing biodiversity can be a daunting if not impossible task. Subsequently, specific taxa are often chosen as indicators of patterns of diversity as a whole. Mapping the locations of indicator taxa can inform conservation planning by identifying land units for management strategies. For this approach to be successful, though, land units must be effective spatial representations of the species assemblages present on the landscape. In this study, I determined whether land units classified by vegetative communities predicted the community structure of a diverse group of invertebrates—the ground beetles (Coleoptera: Carabidae). Specifically, that (1) land units of the same classification contained similar carabid species assemblages and that (2) differences in species structure were correlated with variation in land unit characteristics, including canopy and ground cover, vegetation structure, tree density, leaf litter depth, and soil moisture. The study site, the Braidwood Dunes and Savanna Nature Preserve in Will County, Illinois is a mosaic of differing land units. Beetles were sampled continuously via pitfall trapping across an entire active season from 2011–2012. Land unit characteristics were measured in July 2012. Nonmetric multidimensional scaling (NMDS) ordinated the land units by their carabid assemblages into five ecologically meaningful clusters: disturbed, marsh, prairie, restoration, and savanna.
