1	The Impact of Polypore Fungi on Growth and Physiology of Yellow Birch and Molecular Detection of Fungal Pathogens in Live Trees Mycroft, Erin E. 12 January 2011 (has links) Pathogenic fungi, such as polypore fungi that infect live sapwood, decrease quality and value of wood; however their effects on canopy physiology and growth have been little examined. This study examines how Fomes fomentarius, a species of polypore fungus affects canopy physiology in Betula alleghaniensis. A mobile canopy lift enabled the collection of leaf physiology, morphology and chemistry data from canopies of infected, damaged, and control trees. A molecular protocol developed to detect and identify polypore fungi in live trees confirmed that F. fomentarius was the major species present in infected trees. Infected trees exhibited reductions in physiological performance and growth, along with higher leaf carbon and chlorosis. While some characteristics of fungal infection were consistent with a mechanism involving partial xylem occlusion, patterns did not resemble those of a simple drought response. Likely, other factors such as fungal toxins or host defense mechanisms also contribute to these patterns. forest pathology canopy physiology mycology polypore fungi 0478

3	Occurrence of featherwing beetles (Coleoptera: Ptiliidae) on polypore fungi (Basidiomycota: Agaricomycetes) from Costa Rica and a new species of Cylindrosella Jennifer S Topolski (11174796) 23 July 2021 (has links) <p>Despite being distributed worldwide and easily collected, the biology, ecology, and taxonomy of Ptiliidae Heer, 1843, or featherwing beetles, have not been well studied. In a study from 2007 to 2009, Ptiliidae were extracted from various polypore fungi collected throughout Costa Rica in an effort to expand biogeographic knowledge of Ptiliidae. Fungi and Ptiliidae were identified to genera and collection sites mapped. Beetle genera are able to inhabit different polypore genera and were found at a higher rate of co-occurrence than reported in previous studies. We identified <i>Cylindrosella costariciensis </i><b>sp. n.</b>, with the potential of two more new species to be described.</p> Ecology not elsewhere classified Animal Systematics and Taxonomy Biological Adaptation Mycology Invertebrate Biology Ptiliidae polypore fungi Staphylinoidea taxonomy Costa Rica featherwing beetle new species neotropic Nanosellini Cylindrosella
