The fungal communities associated with Red-cockaded Woodpeckers and their excavations: descriptive and experimental evidence of symbiosis
… cavity-excavators and fungi involve multiple fungal species and are far more complex than previously imagined. Through a field survey, I showed that RCW excavations contain distinct communities of fungi, and propose two hypotheses to explain this result, (1) RCWs select trees with distinct …

Comparative analysis of bacterial and fungal communities in two dairy parlors through the use of pyrosequencing, riboprinting, culture techniques, and microscopic analysis
… and microscopic analysis was used to compare the fungal samples. SKC BioSamplers were used to take area samples inside two modern dairy parlors from May 2012-January 2013. Four sampling sessions were completed at each dairy parlor. Four biosamplers ran side-by-side (two at a time) for 60 minutes …

Functional role of root fungal communities of frailejones (Espeletiinae, Asteraceae) and their response to biotic and abiotic factors in tropical high-altitude grasslands
Los hongos de la rizosfera son actores clave en los procesos del ecosistema del suelo, ya que influyen en el ciclo de nutrientes debido a sus capacidades enzimáticas y su amplio potencial genético. Los rasgos funcionales de las plantas y las variables del suelo pueden influir directamente en las …

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 …

Integrating Above and Belowground Components of Biodiversity across Spatial Scales: The Role of Host Plants in the Distribution of Arbuscular Mycorrhizal Fungi
… heterogeneity and energy availability affect communities; and the relative influence of niche and neutral processes. This thesis describes experiments which profile AM fungal communities and environmental properties of their habitat at different spatial scales in different plant species. …

Belowground Fungal Community Change Associated with Ecosystem Development
… level; however, there are no studies describing fungal community change associated with long-term ecosystem development. To understand ecosystem development, the organisms responsible for shaping and driving these systems and their relationships with the vegetation and soil factors, it is …

Investigating the morphological adaptations and fungal associations of the small hive beetle, Aethina tumida Murray (Coleoptera: Nitidulidae)
… understanding of SHB morphology and associated fungal communities to gain a better understanding of how these beetles protect themselves, exploit honey bee food stores, and maintain their associated fungal communities. This study found no significant differences in tarsal setae characteristics …

Communities of Arbuscular Mycorrhizal Fungi in Salt Marsh Habitats: Diversity, Structure, and Ecosystem Function
… to influence the relationship of rhizosphere fungal communities with each other. Although a range of local abiotic factors significantly influenced the composition of fungal communities within each salt marsh, at larger scales, the compositions of these fungal communities were significantly …

Nitrification inhibitors have minimal impact on microbial and Collembola communities in Danish arable soil
… (NIs) on the soil microbial and collembola communities in arable soils under a spring barley cultivation system. By assessing soils where inhibitors were repeatedly applied alongside fertilizers, we evaluated the short-term effects of NI use on soil biodiversity and function composition …

Factors affecting VA-mycorrhizal community structure in the Namib Dune Field: and the population biology of an ectomycorrhizal Basidiomycete: Suillus granulatus
… Suillus granulatus, were ecology of VAM fungal communities with grasses was studied across a climatic gradient in the hyper-arid central Namib dune field. VAM fungal communities were primarily structured by substrate stability and moisture availability. Five VAM species were found …

The Effects on Soil Fungal Community of Excluding select Above-ground Herbaceous Species in a Montane Longleaf Pine Savanna Restoration Area
… area. Restoration is difficult as vegetation communities constitute a mosaic across the longleaf range. Hence, vegetation description is important wherever longleaf pine communities exist. Vegetation strongly associates with specific soil fungi operational taxonomic units (OTUs) and …

Molecular Analysis of Phenotypic Diversity in Human Fungal Pathogens
Fungal pathogens are a leading cause of human mortality, in part due to their ability to thwart therapeutic regimens by rapidly evolving resistance to antifungal drugs, and their ability to readily adapt to the hostile conditions experienced in a mammalian host. Candida species can colonize various …

Functional diversity of fungal symbiont communities and the impact of biotic and abiotic factors on their composition and assembly
… harbor tremendously diverse microbial symbiont communities (“the microbiome”) that affect the host fitness and response to environmental changes. Despite their importance, less attention has been given to the response of microbial symbionts to environmental difference, the understanding of which …

Where the Spores at? Insights into the Residential Indoor Mycobiome of South Africa
… research on the health implications of fungal proliferation in indoor air, accepted detection and monitoring strategies, and the composition of indoor fungal communities globally and in South Africa. However, IAQ assessment protocols and permissible fungal load thresholds remain …
