Exploring the phylogenetic affiliations and the trophic mode of Sedecula pulvinata (Sedeculaceae)

Creator:: Trappe, Matthew J., Smith, Matthew E., and Hobbie, Erik A.
Abstract:: Sedecula is a monotypic genus of hypogeous fungi that is rare and endemic to dry conifer forests of the western United States. The only known species, Sedecula pulvinata, was described in 1941 and its taxonomic placement and trophic status have remained uncertain ever since. Here we employ isotopic and molecular...

Cryptolepiota, a new sequestrate genus in the Agaricaceae with evidence for adaptive radiation in western North America

Creator:: Kropp, Bradley R., Albee-Scott, Steve, Castellano, Michael A., and Trappe, James M.
Abstract:: Phylogenetic analyses based on nLSU and ITS sequence data indicate that the sequestrate genus Gigasperma is polyphyletic. Gigasperma cryptica, which is known only from New Zealand, has affinities with the Cortinariaceae whereas G. americanum and two additional undescribed taxa from western North America are derived from Lepiota within the Agaricaceae....

New North American truffles (Tuber spp.) and their ectomycorrhizal associations

Creator:: Guevara, Gonzalo, Bonito, Gregory, Trappe, James M., Cazares, Efren, Williams, Gwendolyn, Healy, Rosanne A., Schadt, Christopher, and Vilgalys, Rytas
Abstract:: Recent surveys of belowground fungal biodiversity in Mexico and USA have revealed many undescribed truffle species, including many in the genus Tuber. Here we describe seven new species: Tuber beyerlei, T. castilloi, T. guevarai, T. lauryi, T. mexiusanum, T. miquihuanense and T. walkeri. Phylogenetic analyses place these species within the...

An interdisciplinary framework for evaluating 19th century landscape paintings for ecological research

Creator:: Warren, Dana R., Loeb, Harper M., Betjemann, Peter, Munck, Isabel A., Keeton, William S., Shaw, David C., and Harvey, Eleanor J.
Abstract:: As we contemplate the future of forest landscapes under changing climate conditions and land-use demands, there is increasing value in studying historic forest conditions and how these landscapes have changed following past disturbances. Historic landscape paintings are a potential source of data on preindustrial forests with highly detailed, full-color depictions...

The plant phenology monitoring design for The National Ecological Observatory Network

Creator:: Elmendorf, Sarah C., Jones, Katherine D., Cook, Benjamin I., Diez, Jeffrey M., Enquist, Carolyn A. F., Hufft, Rebecca A., Jones, Matthew O., Mazer, Susan J., Miller-Rushing, Abraham J., Moore, David J. P., Schwartz, Mark D., and Weltzin, Jake F.
Abstract:: Phenology is an integrative science that comprises the study of recurring biological activities or events. In an era of rapidly changing climate, the relationship between the timing of those events and environmental cues such as temperature, snowmelt, water availability, or day length are of particular interest. This article provides an...

Regional variation in stand structure and development in forests of Oregon, Washington, and inland Northern California

Creator:: Reilly, Matthew J. and Spies, Thomas A.
Abstract:: Despite its importance to biodiversity and ecosystem function, patterns and drivers of regional scale variation in forest structure and development are poorly understood. We characterize structural variation, create a hierarchical classification of forest structure, and develop an empirically based framework for conceptualizing structural development from 11,091 plots across 25 million...

Uncertainty analysis: an evaluation metric for synthesis science

Creator:: Harmon, Mark E., Fasth, Becky, Halpern, Charles B., and Lutz, James A.
Abstract:: The methods for conducting reductionist ecological science are well known and widely used. In contrast, those used in the synthesis of ecological science (i.e., synthesis science) are still being developed, vary widely, and often lack the rigor of reductionist approaches. This is unfortunate because the synthesis of ecological parts into...

Multi-scale spatial controls of understory vegetation in Douglas-fir–western hemlock forests of western Oregon, USA

Creator:: Burton, Julia I., Ganio, Lisa M., and Puettmann, Klaus J.
Abstract:: Forest understory vegetation is influenced by broad-scale variation in climate, intermediate-scale variation in topography, disturbance and neighborhood interactions. However, little is known about how these multi-scale controls interact to influence observed spatial patterns. We examined relationships between the aggregated cover of understory plant species (%C[subscript U]) and multi-scale controls using...

Post-fire tree establishment and early cohort development in conifer forests of the western Cascades of Oregon, USA

Creator:: Tepley, Alan J., Swanson, Frederick J., and Spies, Thomas A.
Abstract:: Early‐seral ecosystems make important contributions to regional biodiversity by supporting high abundance and diversity of many plant and animal species that are otherwise rare or absent from closed‐canopy forests. Therefore, the period of post‐fire tree establishment is a key stage in forest stand and ecosystem development that can be viewed...

Interactive visual analysis promotes exploration of long-term ecological data

Creator:: Pham, Tuan, Jones, Julia A., Metoyer, Ronald, Swanson, Frederick, and Pabst, Robert
Abstract:: Long-term ecological data are crucial in helping ecologists understand ecosystem function and environmental change. Nevertheless, these kinds of data sets are difficult to analyze because they are usually large, multivariate, and spatiotemporal. Although existing analysis tools such as statistical methods and spreadsheet software permit rigorous tests of pre-conceived hypotheses and...
