Comparing Fungal Communities In Tsuga Heterophylla Seedling Roots Across Nurse Log Decay Stages And The Forest Floor, Ellie Olpin, Reisha Foertsch
Comparing Fungal Communities In Tsuga Heterophylla Seedling Roots Across Nurse Log Decay Stages And The Forest Floor, Ellie Olpin, Reisha Foertsch
Summer Research
Nurse logs are fallen, decaying trees that have been shown to facilitate the survival, establishment, and growth of tree seedlings, therefore making vital contributions to forest regeneration. Plant-fungi interactions may play a role in influencing seedling survival across nurse log decay and the forest floor. We sought to examine how fungal communities in seedling roots change between nurse logs and forest floor as well as across nurse log decay stages. To study this, we collected western hemlock (Tsuga heterophylla) seedlings (5-10 cm) from nurse logs of each decay stage and the forest floor at three field sites on the Olympic …
A Preliminary Checklist Of Lichens From Kamiak Butte County Park, Washington State, Emma Sell, Amanda Chandler
A Preliminary Checklist Of Lichens From Kamiak Butte County Park, Washington State, Emma Sell, Amanda Chandler
2020 Symposium Posters
The semiarid Palouse ecoregion of North America was once dominated by temperate prairies and connects areas of southeast Washington, north-central Idaho, and northeast Oregon. Transformation of nearly all habitats comprising this ecosystem into agricultural lands has drastically reduced extant native grasslands to small, highly fragmented pieces. These land conversion practices, coupled with the subsequent takeover of invasive plant species, have placed the Palouse ecoregion among the most critically endangered ecosystems in the United States, with < 1% of land remaining that is suitable to host native species. The enormous loss of biodiversity across the Palouse has prompted a need for further study regarding a wide variety of organisms. In particular, lichen diversity of the Palouse ecoregion has never been formally characterized, and there are overall very few detailed studies of lichens throughout eastern Washington. To improve knowledge of Palouse lichen diversity, we first reviewed collection data from historical herbarium specimens via the Consortium of North American Lichen Herbaria (CNALH) database. We then collected lichen voucher specimens from Kamiak Butte County Park (KBCP), one of the largest contiguous natural areas within the Palouse ecoregion as its relatively steep, rocky slopes make it ill-suited for agricultural conversion. KBCP consists of 298 acres of mixed Pinus ponderosa (ponderosa pine) and Pseudotsuga menziesii (Douglas fir) forest and native grassland that rises above the surrounding farmland, as well as an east-west ridgeline …

Much remains to be learned about the biology of mushroom-forming fungi, which are an important source of food, secondary metabolites and industrial enzymes. The wood-degrading fungus Schizophyllum commune is both a genetically tractable model for studying mushroom development and a likely source of enzymes capable of efficient degradation of lignocellulosic biomass. Comparative analyses of its 38.5-megabase genome, which encodes 13,210 predicted genes, reveal the species's unique wood-degrading machinery. One-third of the 471 genes predicted to encode transcription factors are differentially expressed during sexual development of S. commune. Whereas inactivation of one of these, fst4, prevented mushroom formation, inactivation of another, …
Soil Community Structure And Litter Decomposition Under Irrigated Eucalyptus Globulus In South Western Australia, Derek J. Swarts
Soil Community Structure And Litter Decomposition Under Irrigated Eucalyptus Globulus In South Western Australia, Derek J. Swarts
Theses: Doctorates and Masters
Plantations provide a range of benefits, including the potential to ameliorate salinity and soil erosion, enhance biodiversity, and provide timber and wood chips. They are increasingly important because of their role in carbon sequestration (Adolphson, 2000; Anonymous, 2005; Jones et al. , 2005; Kozlowski, 2002; Paul and Polglase, 2004). Recent research has highlighted the connection between plantation health and soil fertility (Johnston and Crossley Jr, 2002). Within an Australian context there is little published data on the composition of the soil and litter fauna and their contribution to litter decomposition under plantation systems (Adolphson, 2000). The Albany Effluent Irrigated Tree …
Response By Reticulitermes (Isoptera: Rhinotermitidae) And Cryptocercus Punctulatus (Blattaria: Cryptocercidae) To Wood Infected With The Green-Stain Ascomycete, Chlorociboria Aeruginascens Aeruginascens, Deborah Waller
Biological Sciences Faculty Publications
Termites of the genus Reticulitermes Holmgren and the wood roaches Cryptocercus punctulatus Scutter were observed feeding on wood stained green by the ascomycete fungus, Chlorociboria aeruginascens aeruginascens (Leotiaceae), in a Virginia forest. However, in laboratory choice trials, both termites and wood roaches preferred unstained wood to stained wood. In no-choice feeding trials, Reticulitermes fed stained birch ate significantly less wood and weighed significantly less than termites fed unstained birch. These results indicate that natural host utilization patterns cannot be relied upon to indicate feeding preferences.

A Survey Of Fungi At The University Of Wisconsin-Waukesha Field Station, Alan D. Parker
Field Station Bulletins
A long-term study of higher fungi and Myxomycetes, primarilyfrom the xeric oak woods, was started in 1978. Collections have been made periodically since then, and recent sampling in conifer plantations indicates that characteristic ectomycorrhizal species of Basidiomycetes are beginning to appear in these communities. To date seven Myxomy-cetes, 22 Ascomycetes, and 107 Basidiomycetes have been identifiedfrom various habitats. These data will be incorporated into a master list of fungi generated from long-term surveys at several additional sites in southeastern Wisconsin.

A Preliminary Survey Of The Fungi Of Sapa Spruce Bog, Alan D. Parker
A Preliminary Survey Of The Fungi Of Sapa Spruce Bog, Alan D. Parker
Field Station Bulletins
An extensive study of the fungi of Sapa Spruce Bog was started during the summer of 1989. The site was divided into three collecting zones the swamp hardwoods surrounding the bog, the tamrac and black spruce zone, and the central, open sphagnum mat zone. Greatest species diversity has been observed in the swamp hardwoods; many fungi identified from this zone have also been recorded from the Field Station beech/maple woods (Parker, 1987 and 1988). Factors contributing to the greater diversity of fungi in this zone include the composition of leaf litter and humus, the larger amount of downed logs in …

Three previous accounts of fungi occurring at the Field Station have appeared in the Bulletin. The first inventory of seventy-five species, including 29 plant pathogens, was published by Baxter (1970). Baxter and Bronaugh (1974) isolated four species of aquatic Hyphomycetes during their study of this group in southeastern Wisconsin. Ciombor and Dibben (1984) identified 29 fungi, 23 of which had not been previously reported. In addition, Baxter (1973) listed the following five fungi as new records for Wisconsin, but did not indicate where they were collected. The present paper reports 71 species, 46 of which are new records. Also included …

Since its reorganization in 1981, one goal of the Wisconsin Mycological Society has been a comprehensive long-term survey of fleshy and other fungi of southeastern Wisconsin. Over a period of years, random collections are to be made at a series of selected foray sites to document spring through fall floras. The UWM Field Station is one of these foray sites. Habitat and locality are to be recorded for each specimen along with field characteristics. Each identified collection will be dried and filed in the herbarium of the Milwaukee Public Museum. To date 35 specimens representing 29 species are on file. …
Key To The Wood-Decaying Polyporaceae Of The East Texas Region, Steve Bishop, W. T. Mcgrath
Key To The Wood-Decaying Polyporaceae Of The East Texas Region, Steve Bishop, W. T. Mcgrath
eBooks
The family includes those pore fungi whose fruiting bodies are tough, leathery or woody and whose pore layer usually cannot be separated easily from the context. The pores on the undersurface are only exterior openings of tubes bearing spores and in each species these tube mouths, or pores, are a definite shape and size. Occasionally pore walls will break up giving the appearance of teeth or gills. Fruiting bodies can be sessile, stemmed, effused-reflexed or resupinate (Fig . 2). Members of the family can be either perennial or annual, with the annual species growing during the summer and maturing that …

Mycological Research At The Field Station, John Baxter
Field Station Bulletins
During the past three years, several mycological research projects have been conducted partially at the Field Station or have used research material obtained at the Station. These include a study of cellulose-digesting fungi from soils of the area (Gatford, 1969), an investigation of lignin digestion by wood-rotting fungi collected at the Station (Flashinski, 1970), and life cycle studies of certain rust fungi of southeastern Wisconsin (Baxter, 1971). At the present time two new mycological research projects are being planned.
