Distribution and Characterization of Podosphaera macularis Virulent on Hop Cultivars Possessing R6-Based Resistance to Powdery Mildew

Creator:: Wolfenbarger, Sierra N., Massie, Stephen T., Ocamb, Cynthia, Eck, Emily B., Grove, Gary G., Nelson, Mark E., Probst, Claudia, Twomey, Megan C., and Gent, David H.
Abstract:: Host resistance, both quantitative and qualitative, is the preferred long-term approach for disease management in many pathosystems, including powdery mildew of hop (Podosphaera macularis). In 2012, an epidemic of powdery mildew occurred in Washington and Idaho on previously resistant cultivars whose resistance was putatively based on the gene designated R6....

Tropical forest fragmentation limits pollination of a keystone understory herb

Creator:: Hadley, Adam S., Frey, Sarah J. K., Robinson, W. Douglas, Kress, W. John, and Betts, Matthew G.
Abstract:: Loss of native vegetation cover is thought to be a major driver of declines in pollination success worldwide. However, it is not well known whether reducing the fragmentation of remaining vegetation can ameliorate these negative effects. We tested the independent effects of composition vs. configuration on the reproductive success of...

Toward predicting community-level effects of climate: relative temperature scaling of metabolic and ingestion rates

Creator:: Iles, Alison C.
Abstract:: Predicting the effects of climate change on ecological communities requires an understanding of how environmental factors influence both physiological processes and species interactions. Specifically, the net impact of temperature on community structure depends on the relative response of physiological energetic costs (metabolism) and energetic gains (ingestion of resources) that mediate...

In defense of P values

Creator:: Murtaugh, Paul A.
Abstract:: Statistical hypothesis testing has been widely criticized by ecologists in recent years. I review some of the more persistent criticisms of P values and argue that most stem from misunderstandings or incorrect interpretations, rather than from intrinsic shortcomings of the P value. I show that P values are intimately linked...

Acetyl-CoA Carboxylase Herbicide Tolerance in Bermudagrass

Creator:: Grimshaw, Austin L., Schwartz, Brian M., Grey, Timothy L., McCullough, Patrick E., Raymer, Paul L., Webster, Theodore M., Kowalewski, A. R., Tate, Trent M., and Parrott, Wayne A.
Abstract:: Contamination of newly planted bermudagrass (Cynodon spp.) varieties by undesirable off-type bermudagrass genotypes is an ever increasing concern for turf managers because selective control options are limited. In 2009, a sethoxydim {2-[1-(ethoxyimino)butyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-1-one} tolerant bermudagrass genotype (93-175) was identified during herbicide screening at the University of Georgia in Tifton. The objective...

Disentangling the cause of a catastrophic population decline in a large marine mammal

Creator:: Baylis, Alastair M. M., Orben, Rachael A., Arnould, John P. Y., Christiansen, Fredrik, Hays, Graeme C., and Staniland, Iain J.
Abstract:: Considerable uncertainties often surround the causes of long-term changes in population abundance. One striking example is the precipitous decline of southern sea lions (SSL; Otaria flavescens) at the Falkland Islands, from 80 555 pups in the mid 1930s to just 5506 pups in 1965. Despite an increase in SSL abundance over...

Ecological strategies predict associations between aquatic and genetic connectivity for dryland amphibians

Creator:: Mims, Meryl C., Phillipsen, Ivan C., Lytle, David A., Kirk, Emily E. Hartfield, and Olden, Julian D.
Abstract:: The study of how population genetic structure is shaped by attributes of the environment is a central scientific pursuit in ecology and conservation. But limited resources may prohibit landscape genetics studies for many threatened species, particularly given the pace of current environmental change. Understanding the extent to which species' ecological...

Barro Colorado Island’s phylogenetic assemblage structure across fine spatial scales and among clades of different ages

Creator:: Pearse, William D., Jones, F. Andrew, and Purvis, Andy
Abstract:: Phylogenetic analyses of assemblage membership provide insight into how ecological communities are structured. However, despite the scale-dependency of many ecological processes, little is known about how assemblage and source pool size definitions can be altered, either alone or together, to provide insight into how ecological diversity is maintained. Moreover, although...

Beyond dichotomous life histories in partially migrating populations: cessation of anadromy in a long-lived fish

Creator:: Bond, Morgan H. and Miller, Jessica A.
Abstract:: Across animal taxa, migration allows individuals to exploit habitats and resources that predictably vary seasonally in suitability. Theory predicts that the ‘‘decision’’ to migrate or not is shaped by the relative fitness costs and benefits of exhibiting a given life history. Adoption of a migratory strategy is widely thought to...
