Abstract:
[Truncated abstract] Spontaneous plant growth and soil development occur at disturbed sites with their extent and nature being variously affected by soil fertility status, local climate and topographic conditions. Soil-plant interactions can be diverse and site-specific within a disturbed landscape. The main purpose of the present study is to evaluate soil characteristics and landscape indices in relation to natural plant growth and soil development under different conditions and for diverse materials. A comprehensive study has been carried out to evaluate spontaneous soil development and pl

Abstract:
Integrated pest management (IPM) uses multiple approaches to keep pest levels below economic injury levels. Integrated pest management combines preventative methods such as biocontrol with curative methods; this synthesis requires an understanding of the ecology of natural enemies in the agroecosystem. Arthropod natural enemy communities in apple orchards are diverse, and spiders (Araneae) are particularly abundant and species rich. Orchard arthropods are affected by multiple factors, both external (e.g. immigration) and internal (e.g. pesticides) to the orchard environment. In this thesis

Abstract:
Arbuscular mycorrhizal fungi, colonizing over 80% of all plants, were long thought absent in wetlands; however, recent studies have shown many wetland plants harbor arbuscular mycorrhizae (AM) and dark septate endophytes (DSE). Wetland services such as biodiversity, shoreline stabilization, water purification, flood control, etc. have been estimated to have a global value of $14.9 trillion. Recognition of these vital services is accompanied by growing concern for their vulnerability and continued loss, which has resulted in an increased need to understand wetland plant communities and mycorrhi

Abstract:
Mesobenthic amphipods (2-15 mm) constitute an important faunal component of coastal ecosystems, and often represent a major trophic link between primary producers and fishes. However, obtaining basic demographic data on these taxa is often hindered by a lack of suitable non-destructive, quantitative, collection techniques. Although artificial substrates have been advocated for collecting data at these lower trophic levels, recent studies suggest that they may not accurately represent the natural benthic assemblage. This study evaluated how a structurally-complex artificial substrate (3-dimensi

Her (mistaken) belief is that Locke’s political philosophy encourages social disengagement and political apathy.

abstract: Biological soil crusts (biocrust) are photosynthetic communities of organisms forming in the top millimeters of unvegetated soil. Because soil crusts contribute several ecosystem services to the areas they inhabit, their loss under anthropogenic pressure has negative ecological consequences. There is a considerable interest in developing technologies for biocrust restoration such as biocrust nurseries to grow viable inoculum and the optimization of techniques for field deployment of this inoculum. For the latter, knowledge of the natural rates of biocrust dispersal is needed. Lateral
