Relationships between Swiss needle cast and ectomycorrhizal fungus diversity

Creator:: Luoma, Daniel L. and Eberhart, Joyce L.
Abstract:: Swiss needle cast (SNC) is a disease specific to Douglas-fir (Pseudotsuga menziesii) caused by the ascomycete Phaeocryptopus gaeumannii. Here we examine characteristics of the EM fungus community that are potentially useful in predictive models that would monitor forest health. We found that mean EM density (number of colonized root tips/soil...

Entomopathogens of Amazonian stick insects and locusts are members of the Beauveria species complex (Cordyceps sensu stricto)

Creator:: Sanjuan, Tatiana, Tabima, Javier, Restrepo, Silvia, Læssøe, Thomas, Spatafora, Joseph W., and Esperanza Franco-Molano, Ana
Abstract:: In the Amazon the only described species of Cordyceps sensu stricto (Hypocreales, Cordycipitaceae) that parasitize insects of Orthopterida (orders Orthoptera and Phasmida) are Cordyceps locustiphila and C. uleana. However, the type specimens for both taxa have been lost and the concepts of these species are uncertain. To achieve a more...

Sequestrate fungi from Patagonian Nothofagus forests: Cystangium (Russulaceae, Basidiomycota)

Creator:: Trierveiler-Pereira, Larissa, Smith, Matthew E., Trappe, James M., and Nouhra, Eduardo R.
Abstract:: Six species of Cystangium, a genus of sequestrate taxa related to Russula, were collected in Patagonia (Argentina and Chile) during autumn 2001. Two species, C. depauperatum Singer & A.H. Sm. and C. nothofagi (E. Horak) Trappe, Castellano & T. Lebel, were already known from this region, while four new species,...

Rhizopogon togasawariana sp. nov., the first report of Rhizopogon associated with an Asian species of Pseudotsuga

Creator:: Mujic, Alija B., Hosaka, Kentaro, and Spatafora, Joseph W.
Abstract:: Rhizopogon subgenus Villosuli are the only members of the genus known to form an ectomycorrhizal relationship exclusively with Pseudotsuga. The specificity of this host relationship is unusual in that Rhizopogon is broadly associated with several tree genera within the Pinaceae and relationships with a host genus are typically distributed across...

Fertilization of Epichloë typhina stromata by mycophagous slugs

Creator:: Hoffman, George D. and Rao, Sujaya
Abstract:: Epichloë typhina, a fungal endophyte of cool season grasses, is heterothallic and an obligate out-crosser. In areas of endemism, its spermatia are moved between stromata of the two opposite mating types through egg-laying activities of Botanophila flies. In western Oregon, where the fungus was inadvertently introduced into seed-production fields of...

Morchella australiana sp. nov., an apparent Australian endemic from New South Wales and Victoria

Creator:: Elliott, Todd F., Bougher, Neale L., O'Donnell, Kerry, and Trappe, James M.
Abstract:: An abundant fruiting of a black morel was encountered in temperate northwestern New South Wales (NSW), Australia, during a mycological survey in Sep 2010. The site was west of the Great Dividing Range in a young, dry sclerophyll forest dominated by Eucalyptus and Callitris north of Coonabarabran in an area...

The role of pre-event canopy storage in throughfall and stemflow by using isotopic tracers

Creator:: Allen, S. T., Brooks, J. R., Keim, R. F., Bond, B. J., and McDonnell, J. J.
Abstract:: Stable isotopes can be a valuable tool for tracing the redistribution, storage, and evaporation of water associated with canopy interception of rainfall. Isotopic differences between throughfall and rainfall have been attributed to three mechanisms: evaporative fractionation, isotopic exchange with ambient vapor, and temporal redistribution. We demonstrate the potential importance of...

Ecohydrological consequences of drought‐ and infestation‐triggered tree die‐off: insights and hypotheses

Creator:: Adams, Henry D., Luce, Charles H., Breshears, David D., Allen, Craig D., Weiler, Markus, Hale, V. Cody, Smith, Alistair M. S., and Huxman, Travis E.
Abstract:: Widespread, rapid, drought-, and infestation-triggered tree mortality is emerging as a phenomenon affecting forests globally and may be linked to increasing temperatures and drought frequency and severity. The ecohydrological consequences of forest die-off have been little studied and remain highly uncertain. To explore this knowledge gap, we apply the extensive...

Adaptive genetic markers discriminate migratory runs of Chinook salmon (Oncorhynchus tshawytscha) amid continued gene flow

Creator:: O'Malley, Kathleen G., Jacobson, Dave P., Kurth, Ryon, Dill, Allen J., and Banks, Michael A.
Abstract:: Neutral genetic markers are routinely used to define distinct units within species that warrant discrete management. Human-induced changes to gene flow however may reduce the power of such an approach. We tested the efficiency of adaptive versus neutral genetic markers in differentiating temporally divergent migratory runs of Chinook salmon (Oncorhynchus...
