Background: Foliar fungicide applications to corn (Zea mays) occur at one or more application timings ranging from early vegetative growth stages to mid-reproductive stages. Previous studies indicated that fungicide applications are profitable under high disease pressure when applied during the tasseling to silking growth stages. Few comprehensive studies in corn have examined the impact of fungicide applications at an early vegetative growth stage (V6) compared to late application timings (VT) for yield response and return...

5/ Writing and filming queer deaths

Joshua G. Adair, Stacey Berry, Giulia Bigongiari, Mél Hogan & Anna Chiara Corradino
This is part 5 of 6 of the dossier What do we talk about when we talk about queer death?, edited by M. Petricola. The contributions collected in this article sit at the crossroads between thanatology, critical animal studies, and the posthumanities and tackle questions such as: how can we re-interpret literature, film, and media products through the lens of queer death studies? And how can we rethink death, dying, and disposal through literature, film,...

Data from: Herbicide resistance-endowing ACCase gene mutations in hexaploid wild oat (Avena fatua): Insights into resistance evolution in a hexaploid species

Stephen Powles, Qin Yu, M. S. Ahmad-Hamdani, Heping Han & Michael Christoffers
Many herbicide-resistant weed species are polyploids, but far too little about the evolution of resistance mutations in polyploids is understood. Hexaploid wild oat (Avena fatua) is a global crop weed and many populations have evolved herbicide resistance. We studied plastidic acetyl-coenzyme A carboxylase (ACCase)-inhibiting herbicide resistance in hexaploid wild oat and revealed that resistant individuals can express one, two or three different plastidic ACCase gene resistance mutations (Ile-1781-Leu, Asp-2078-Gly and Cys-2088-Arg). Using ACCase resistance mutations...

Data from: Non-consumptive effects of predation: does perceived risk strengthen the genetic integration of behaviour and morphology in stickleback?

Niels Dingemanse, Iain Barber & Ned Dochtermann
Predators can shape genetic correlations in prey by altering prey perception of risk. We manipulated perceived risk to test whether such non-consumptive effects tightened behavioural trait correlations in wild-caught stickleback from high- compared to low-risk environments due to genetic variation in plasticity. We expected tighter genetic correlations within perceived risk treatments than across them, and tighter genetic correlations in high-risk than in low-risk treatments. We identified genetic variation in plasticity, with genetic correlations between boldness,...

Data from: Binary-state speciation and extinction method is conditionally robust to realistic violations of its assumptions

Andrew G. Simpson, Peter J. Wagner, Scott L. Wing & Charles B. Fenster
Background: Phylogenetic comparative methods allow us to test evolutionary hypotheses without the benefit of an extensive fossil record. These methods, however, make simplifying assumptions, among them that clades are always increasing or stable in diversity, an assumption we know to be false. This study simulates hypothetical clades to test whether the Binary State Speciation and Extinction (BiSSE) method can be used to correctly detect relative differences in diversification rate between ancestral and derived character states...

Data from: Inferring outcrossing in the homothallic fungus Sclerotinia sclerotiorum using linkage disequilibrium decay

Weidong Chen, Renuka N. Attanayake, Vidhura Tennekoon, Dennis A. Johnson, Lyndon D. Porter, Luis Del Río-Mendoza & Daohong Jiang
The occurrence and frequency of outcrossing in homothallic fungal species in nature is an unresolved question. Here we report detection of frequent outcrossing in the homothallic fungus Sclerotinia sclerotiorum. In using multilocus linkage disequilibrium (LD) to infer recombination among microsatellite alleles, high mutation rates confound the estimates of recombination. To distinguish high mutation rates from recombination to infer outcrossing, 8 population samples comprising 268 S. sclerotiorum isolates from widely distributed agricultural fields were genotyped for...
