Creator:: McIver, James D., Stephens, Scott L., Agee, James K., Barbour, Jamie, Boerner, Ralph E. J., Edminster, Carl B., Erickson, Karen L., Farris, Kerry L., Fettig, Christopher J., Fiedler, Carl E., Haase, Sally, Hart, Stephen C., Keeley, Jon E., Knapp, Eric E., Lehmkuhl, John F., Moghaddas, Jason J., Otrosina, William, Outcalt, Kenneth W., Schwilk, Dylan W., Skinner, Carl N., Waldrop, Thomas A., Weatherspoon, C. Phillip, Yaussy, Daniel A., Youngblood, Andrew, and Zack, Steve
Abstract:: The 12-site National Fire and Fire Surrogate study (FFS) was a multivariate experiment that evaluated ecological consequences of alternative fuel-reduction treatments in seasonally dry forests of the US. Each site was a replicated experiment with a common design that compared an un-manipulated control, prescribed fire, mechanical and mechanical + fire...

The enigmatic truffle Fevansia aurantiaca is an ectomycorrhizal member of the Albatrellus lineage

Creator:: Smith, Matthew E., Schell, Karlee J., Castellano, Michael A., Trappe, Matthew J., and Trappe, James M.
Abstract:: Fevansia aurantiaca is an orange-colored truffle that has been collected infrequently in the Pacific Northwest of the USA. This sequestrate, hypogeous fungus was originally thought to be related to the genera Rhizopogon or Alpova in the Boletales, but the large, inflated cells in the trama and the very pale spore...

Experimental brood enlargement differentially influences the magnitude of the corticosterone stress response in closely related, co-occurring songbirds

Creator:: Hardt, Braelei M., Ardia, Daniel R., Bashaw, Meredith J., and Rivers, James W.
Abstract:: 1. Rearing environments can shape offspring phenotype across taxa, yet little is known about how brood size influences hypothalamic-pituitary axis functioning, whether its expression trades off with growth, and the degree to which these -relationships vary between species. 2. We evaluated how brood size influenced nestling physiological (glucocorticoids) and somatic...

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....

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...

Conditions favouring Bromus tectorum dominance of endangered sagebrush steppe ecosystems

Creator:: Reisner, Michael D., Grace, James B., Pyke, David A., and Doescher, Paul S.
Abstract:: 1. Ecosystem invasibility is determined by combinations of environmental variables, invader attributes, disturbance regimes, competitive abilities of resident species and evolutionary history between residents and disturbance regimes. Understanding the relative importance of each factor is critical to limiting future invasions and restoring ecosystems. 2. We investigated factors potentially controlling Bromus...

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...

The Roles of Large Top Predators in Coastal Ecosystems: New Insights from long Term Ecological Research

Creator:: Rosenblatt, Adam E., Heithaus, Michael R., Mather, Martha E., Matich, Philip, Nifong, James C., Ripple, William J., and Silliman, Brian R.
Abstract:: Abstract: During recent human history, human activities such as overhunting and habitat destruction have severely impacted many large top predator populations around the world. Studies from a variety of ecosystems show that loss or diminishment of top predator populations can have serious consequences for population and community dynamics and ecosystem...

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...

Calculating CO2 and H2O eddy covariance fluxes from an enclosed gas analyzer using an instantaneous mixing ratio

Creator:: Burba, George, Schmidt, Andres, Scott, Russell L., Nakai, Taro, Kathilankal, James, Fratini, Gerardo, Hanson, Chad, Law, Beverly, McDermitt, Dayle K., Eckles, Robert, Furtaw, Michael, and Velgersdyk, Michael
Abstract:: Eddy covariance flux research has relied on open- or closed-path gas analyzers for producing estimates of net ecosystem exchange of carbon dioxide (CO₂) and water vapor (H₂O). The two instruments have had different challenges that have led to development of an enclosed design that is intended to maximize strengths and...
