Is fire exclusion in mountain big sagebrush communities prudent? Soil nutrient, plant diversity and arthropod response to burning

Creator:: Davies, Kirk W., Bates, Jonathan D., Boyd, Chad S., and Nafus, Aleta M.
Abstract:: Fire has largely been excluded from many mountain big sagebrush communities. Managers are reluctant to reintroduce fire, especially in communities without significant conifer encroachment, because of the decline in sagebrush-associated wildlife. Given this management direction, a better understanding of fire exclusion and burning effects is needed. We compared burned to...

Agave salmiana Plant Communities in Central Mexico as Affected by Commercial Use

Creator:: Martinez Salvador, Martin, Mata-Gonzalez, Ricardo, Morales Nieto, Carlos, and Valdez-Cepeda, Ricardo
Abstract:: Agave salmiana is a native plant species harvested for the commercial production of mezcal (Agave spirits) in the highlands of central Mexico. The objective of this study was to identify vegetation changes in natural communities where A. salmiana has been differentially harvested for commercial purposes. Three plant community categories were...

Are Early Summer Wildfires an Opportunity to Revegetate Exotic Annual Grass–Invaded Plant Communities?

Creator:: Davies, Kirk W., Nafus, Aleta M., and Johnson, Dustin D.
Abstract:: Medusahead (Taeniatherum caput-medusae [L.] Nevski) is an exotic annual grass invading western rangelands. Successful revegetation of invaded-plant communities can be prohibitively expensive because it often requires iterative applications of integrated control and revegetation treatments. Prescribed burning has been used to control medusahead and prepare seedbeds for revegetation, but burning has...

Abstract:: The Arabidopsis Information Portal (AIP), a resource expected to provide access to all community data and combine outputs into a single user-friendly interface, has emerged from community discussions over the last 23 months. These discussions began during two closely linked workshops in early 2010 that established the International Arabidopsis Informatics...

Genetic diversity of the narrow endemic Astragalus oniciformis (Fabaceae)

Creator:: Alexander, J. Andrew, Liston, Aaron, and Popovich, Steve J.
Abstract:: Astragalus oniciformis Barneby is a narrow endemic xerophyte of the upper Snake River Plain of central Idaho, USA, where it inhabits stabilized, aeolian sand deposits and previously burned, sandy sites over Quaternary basalt flows. The objective of this study was to determine the levels and distribution of genetic differentiation within...

Abstract:: Human alterations to nutrient cycles[superscript 1,2] and herbivore communities³⁻⁷ are affecting global biodiversity dramatically². Ecological theory predicts these changes should be strongly counteractive: nutrient addition drives plant species loss through intensified competition for light, whereas herbivores prevent competitive exclusion by increasing ground-level light, particularly in productive systems[superscript 8,9]. Here we...

Large-Scale Downy Brome Treatments Alter Plant-Soil Relationships and Promote Perennial Grasses in Salt Desert Shrublands

Creator:: Schantz, Merilynn C., Monaco, Thomas A., Call, Christopher A., and Sheley, R. L.
Abstract:: Because invasive annual grasses can strongly influence soil resource availability and disturbance regimes to favor their own persistence, there is a great need to understand the interrelationships among invasive plant abundance, resource availability, and desirable species prominence. These interrelationships were studied in two salt desert sites where the local abundance...

Diversity of Foliar Phytophthora Species on Rhododendron in Oregon Nurseries

Creator:: Knaus, B. J., Fieland, V. J., Graham, K. A., and Grünwald, N. J.
Abstract:: The genus Phytophthora contains some of the most notorious plant pathogens affecting nursery crops. Given the recent emergence of the sudden oak death pathogen Phytophthora ramorum, particularly in association with Rhododendron spp., characterization of Phytophthora communities associated with this host in nursery environments is prudent. Many taxa may present symptoms...

Comparative Composition, Diversity and Trophic Ecology of Sediment Macrofauna at Vents, Seeps and Organic Falls

Creator:: Bernardino, Angelo F., Levin, Lisa A., Thurber, Andrew R., and Smith, Craig R.
Abstract:: Sediments associated with hydrothermal venting, methane seepage and large organic falls such as whale, wood and plant detritus create deep-sea networks of soft-sediment habitats fueled, at least in part, by the oxidation of reduced chemicals. Biological studies at deep-sea vents, seeps and organic falls have looked at macrofaunal taxa, but...

Population structure and genetic diversity of Botrychium pumicola (Ophioglossaceae) based on inter-simple sequence repeats (ISSR)

Creator:: Camacho, Francisco J. and Liston, Aaron
Abstract:: Species of Botrychium reproduce by spores that form subterranean gametophytes and a few, like B. pumicola, also reproduce asexually with subterranean sporophytic gemmae. The goal of this study was to examine the genetic diversity of B. pumicola populations and to better understand the role of gemmae. Ninety-nine individuals from three...
