What lies beneath? Fungal diversity at the bottom of the Great Lakes
… cycling and decomposition. To date, most fungal diversity has been documented from terrestrial habitats leaving aquatic habitats rarely explored. Even less is known about fungi inhabiting freshwater lakes, particularly the benthic zone that may serve as an untapped resource for fungal …

Fostering Populations of Arbuscular Mycorrhizal Fungi Through Cover Crop Choices and Soil Management
… practices can negatively influence both the diversity, and abundance of the AM fungi. It is therefore desirable to identify farming practices or amendments that can foster these fungal populations to increase crop and soil benefits, including yield. Cover cropping, the growing of non-food …

Soil Microbial Diversity and Litter Decomposition Increase with Time Since Land Use Disturbance in Tropical Montane Forests of Malaysian Borneo
… disturbances alter soil chemistry, microbial diversity, and disrupt carbon cycling through shifts in litter decomposition. Direct links between microbial diversity and soil properties such as pH are well established; however, the indirect impacts of logging and forest conversion on microbial …

Next-Generation Approaches to Understanding the Diversity and Evolution of Marine Fungi
… lineages, with estimates of total global diversity projecting millions of species that have yet to be cataloged. Though fungi from all phyla and habitats await discovery, marine fungi are particularly poorly understood. Historical surveys of fungi in marine habitats, which relied primarily …

The relationship between dominant forest mycorrhizal type and the belowground mycobiome of the sugar maple and eastern hemlock
… instances, biotic (e.g., mycorrhizal regimes and fungal communities) and abiotic conditions (e.g., soil chemistry) may act as important filters that potentially impede these migration and adaptation scenarios. Given that dominant forest mycorrhizal types are known to have strong impacts on …

Legacy effects of cover crop monocultures and mixtures on soil inorganic nitrogen, total phenolic content, and microbial communities on two organic farms in Illinois
… changes in microbial community structure and -diversity as a result of cover crop type as well as identified specific cover crop drivers that were associated with individual microbial taxa using partial least squares regression (PLSR) modeling. I found the greatest bacterial -diversity under …

Sooty mould populations on kiwifruit: post harvest and seasonal variation : A thesis submitted in partial fulfilment of the requirements for the Degree of Master at Lincoln University
… due to sooty mould. This study identified the fungal organisms constituting sooty mould on green-fleshed Actinidia chinensis var. deliciosa ‘Hayward’ and A. chinensis var. chinensis ‘Zesy002’ (informally referred to as Gold3) during cool storage and on ‘Zesy002’ throughout a single, growing …

Development of molecular tools for rapid detection and quantification of indoor airborne molds to assess their impact on public health
… still limited. The monitoring of indoor airborne fungal contamination is a common tool to help understanding the link between fungi in houses and respiratory problems. Classical monitoring methods, based on cultivation and microscopic identification, have some limitations. For example, …

Assessing Diversity, Culturability and Context-dependent Function of the Amphibian Skin Microbiome
… a major driver of the accelerated rates of biodiversity loss that are being documented around the world. Global losses of amphibians provide evidence of this, especially those associated with chytridiomycosis, a lethal skin disease caused by the fungus Batrachochytrium dendrobatidis (Bd). …

The Fungal Connection: Characterizing the Ectomycorrhizal Community and Belowground Response to Restoration Treatments in Northern Mississippi.
… certain dominant plant taxa, knowledge of ECM fungal response is needed to ensure restoration efforts succeed. Using molecular methods, this research aimed to identify the ECM fungal community in a restoration project in northern Mississippi, comparing the belowground fungal community on plant …

Emydomyces testavorans infection in aquatic chelonians
… declines in North American bat populations. The fungal order Onygenales includes many pathogens of humans and animals, and recent studies have shown some onygenalean fungi to be significant emerging pathogens of reptiles, most notably Nannizziopsis, Paranannizziopsis, and Ophidiomyces. Infections …

Functional diversity of fungal symbiont communities and the impact of biotic and abiotic factors on their composition and assembly
… dominant members of the plant microbiomes, the fungal endophytes, the main goal of this research was to investigate how the ecological context affect microbial symbiont community structure and assembly. To do that, first, I investigated patterns of carbon resource use and growth of fungal …

Trace metal effects on ectomycorrhizal growth, diversity, and colonization of host seedlings
Ectomycorrhizal fungi are essential to seedling establishment in disturbed sites. This dissertation examines the effects of trace metals and soil disturbance on ectomycorrhizal fungi in the laboratory and the field. The first experiment assessed Cu and Zn impact on growth of three ectomycorrhizal …

Microbiome associated with Ulva lacinulata and seawater in an integrated abalone (Haliotis midae)–Ulva system with partial recirculation
… this study aimed to characterise the bacterial, fungal, and oomycete communities associated with seawater and Ulva in an integrated abalone-Ulva farm with 50% water recirculation. The study was conducted on a commercial abalone farm along the South-Western Cape coast of South Africa. Water (N = …
