Data from: Comparing the efficacy of control strategies for infectious disease outbreaks using field and simulation studies
<p>Diseases characterized by long distance inoculum dispersal (LDD) are among the fastest spreading epidemics in both natural and managed landscapes. Management of such epidemics is extremely challenging because of asymptomatic infection extending at large spatial scales and frequent escape from the newly established disease sources. We compared the efficacy of area- and timing-based disease management strategies in artificially initiated field epidemics of wheat stripe rust and complemented with simulations from an updated version of the spatially explicit model EPIMUL, using model parameters relevant to field epidemics. The model was further used to expand the number of epidemic mitigations beyond that feasible to incorporate in the field. The field experiment was conducted for two years in two locations having different climatic conditions. Culling and protection treatments were applied at different times after epidemic initiation and to different spatial extents surrounding the outbreaks. In each experiment, treatments were replicated four times in plots 33.5 m long and 1.52 m wide with a 0.76 x 0.76 m inoculated focus centered within each plot. Disease gradients were assessed along the center lines of the plots at 1.52 m intervals both upwind and downwind from the focus. Both field and simulation results indicated that control measures applied over the entire population were highly effective in suppressing the epidemics by more than 99% but may not always be logistically and economically feasible at large spatial scales. Comparison between the variable sized treatment areas and application timings suggested that implementing contiguous premises (CP) cull at 1 day after first sporulation in the outbreak focus reduced rust by 52 and 60% in Corvallis and Madras, respectively. However, altering the cull size did not significantly affect the disease epidemic development, which suggested that early timing had a greater influence in suppressing the epidemics than did increased area of application. However, sufficiently large, treated areas may compensate for a delay in application timing to some extent. Results from these replicated treatments may help to devise appropriate management strategies for other LDD pathogens. </p>

Strategies for Inclusion in Data Literacy Programming
<p>Jonathan Cain founded the Data Services Department at the University of Oregon with a goal of to prioritizing the needs of under-served students. The focus of our statistical consulting service and data literacy workshops has been to fulfill that vision. In this talk we discuss some of our strategies for reaching under-served students (students of color, immigrants, non-traditional students, and women in male-dominated fields), including the following: hiring students of color, international, and non-traditional students to provide peer consulting services and help lead workshops, and creating a welcoming environment for all students. This has meant, for example, offering a workshop sequence teaching R in Chinese (not common at a US university), and hiring a student specifically to liaise with and offer services to the McNair Scholars Program, a program for underrepresented undergraduate students who intend to pursue a PhD. As time allows, we will also address the limitations of our strategies and invite feedback from audience members about what strategies have worked at their institutions.</p>

Environmental data from: Feeding strategy and dietary preference shape the microbiome of epipelagic copepods in a warm nutrient-impoverished ecosystem
<p><span>Copepods provide a rich organic microenvironment allowing the settlement and proliferation of microorganisms, forming dynamic microbial hotspots in the oceans. Such symbiotic associations in the plankton were previously hypothesized to be especially developed in warm oligotrophic seas, as they may serve as alternative sources of nutrients in biologically-poor waters. Aiming to better understand how copepod microbiomes are shaped in an oligotrophic sea, we characterized microbiota associated with three dominant coastal epipelagic copepod species in the ultra-oligotrophic Eastern Mediterranean Sea using amplicon sequencing of the 16S rRNA gene</span><span>. Our results show that copepod-associated microbial communities were host-specific rather than determined by seasonal environmental changes. In the filter-feeding copepod with a tendency to herbivory, <em>Temora stylifera</em>, microbial diversity was low and relatively stable throughout the year. In contrast, omnivorous copepods, the ambush-feeding <em>Oithona nana</em>, and the mixed-feeding <em>Centropages ponticus</em> harbored more diverse microbiomes dominated by transient taxa. We suggest that filter-feeding strategy and narrow food spectrum can limit copepod-microbe interactions, while the ambush and mixed feeding strategies combined with omnivory confer higher microbial diversity. Filter feeders may reduce the recruitment of opportunistic microbes by maintaining high fidelity associations, as indicated by the large number of core taxa in <em>T. stylifera</em>. We underline the importance of the copepod-microbe associations in nutrient-impoverished ecosystems, based on predicted enrichment of nitrogen metabolism in the core micro</span>biome<span>, mostly during summer when the shallow coastal waters are nitrogen-depleted. </span></p>
Data from: The role of non-natural foods in the nutritional strategies of monkeys in a human-modified mosaic landscape
<p>Many tropical animals inhabit mosaic landscapes including human-modified habitat. In such landscapes, animals commonly adjust feeding behavior, and may incorporate non-natural foods. These behavioral shifts can influence consumers' nutritional states, with implications for population persistence. However, few studies have addressed the nutritional role of non-natural food. We examined nutritional ecology of wild blue monkeys to understand how dietary habits related to non-natural foods might support population persistence in a mosaic landscape. We documented prevalence and nutritional composition of non-natural foods in monkey diets to assess how habitat use influenced their consumption and their contribution to nutritional strategies. While most energy and macronutrients came from natural foods, subjects focused non-natural feeding activity on five exotic plants and averaged about a third of daily calories from non-natural foods. Most non-natural food calories came from non-structural carbohydrates and least from protein. Consumption of non-natural foods related to time in human-modified habitats, which two groups used non-randomly. Non-natural and natural foods were similar in nutrients, and the amount of non-natural food consumed drove variation in nutritional strategy. When more daily calories came from non-natural foods, females consumed a higher ratio of non-protein energy to protein (NPE:P). Females also prioritized protein while allowing NPE:P to vary, increasing NPE while capitalizing on non-natural foods. Overall, these tropical mammals achieved a similar nutrient balance regardless of their intake of non-natural foods. Forest and forest-adjacent areas with non-natural vegetation may provide adequate nutrient access for consumers, and thus contribute to wildlife conservation in mosaic tropical landscapes.</p>
Data from: Evolutionary radiation strategy revealed in the Scarabaeidae with evidence of continuous spatiotemporal morphology and phylogenesis
<p>Evolutionary biology faces the important challenge of determining how to interpret the relationship between selection pressures and evolutionary radiation. The lack of morphological evidence on cross-species research adds to difficulty of this challenge.</p> <p>We proposed a new paradigm for evaluating the evolution of branches through changes in characters on continuous spatiotemporal scales, for better interpreting the impact of biotic/abiotic drivers on the evolutionary radiation. It reveals a causal link between morphological changes and selective pressures: consistent deformation signals for all tested characters on timeline, which provided strong support for the evolutionary hypothesis of relationship between scarabs and biotic/abiotic drivers; the evolutionary strategies under niche differentiation, which were manifested in the responsiveness degree of functional morphological characters with different selection pressure.</p> <p>This morphological information-driven integrative approach sheds light on the mechanism of macroevolution under different selection pressures and is applicable to more biodiversity research.</p>

Data from: Spatiotemporal interaction of risk-spreading strategies for a seed-dimorphic plant
<p>For plants, the risk of stress-induced reproductive failure can be spread temporally and spatially by increasing the variation in stress tolerance and dispersibility, respectively. Yet, we have limited understanding on how intraspecific stress tolerance can be interactively adjusted by these two risk-spreading strategies. Seed-dimorphic plants, which are frequently found in stressful and fluctuating environments, can produce dimorphic offspring with different stress tolerances and dispersibilities. Using a seed-dimorphic Asteraceae,<em> Synedrella nodiflora</em>, we illustrated how maternal-drought-induced changes in drought tolerance and dispersibility may interactively increase intraspecific drought tolerance variation, and thus potentially improve adaptation to various water conditions. Maternal drought stress increased the mean or variation of drought tolerance of the less-dispersible (R-type) offspring, whereas it had variable effects on the drought tolerance of the more-dispersible (D-type) offspring depending on maternal seed morph (R-type vs. D-type) and habitat (dry vs. wet). Because the relative abundances of these two types of offspring remained largely unchanged by maternal drought, there was an overall increase in the intraspecific mean and variation of drought tolerance under maternal drought stress, driven by the changes in the less-dispersible offspring.</p> <p>Synthesis. Our results indicate a strong interaction between stress tolerance variation and seed dispersibility in seed-dimorphic plant species. Using drought tolerance as an indicator, we demonstrate a potential pathway for the adaptive evolution of seed-dimorphic plants that may contribute to their wide distribution. More importantly, our findings highlight the ecological significance of seed dimorphism and the variation of stress tolerance to avoid reproductive failure under various environmental conditions.</p> <pre> </pre>

Data from: Oviposition strategies of Pieridae butterflies in nature and the role of an egg-killing plant trait therein
<p>Most herbivorous insects are host-plant specialists that evolved detoxification mechanisms to overcome their host plant's toxins. In the evolutionary arms-races between Pieridae butterflies and Brassicaceae plants, some plant species have evolved another defence against the pierids: egg-killing. Underneath the eggs, leaves develop a so-called hypersensitive response HR-like cell death. Whether some butterflies have evolved oviposition strategies to counter-adapt against egg-killing remains to be studied. In this study, we assessed the oviposition site location of pierid butterflies on their natural host plants. We described the plant tissue on which we located the eggs of the most common Pieridae in the Netherlands: <em>Gonepteryx rhamni, Anthocharis cardamines, Pieris rapae, P. napi, P. brassicae,</em> and<em> P. mannii</em>. Additionally, we assessed expression of HR-like cell death in response to the deposited butterfly eggs. We found that both <em>A. cardamines </em>and <em>G. rhamni </em>mainly oviposited on the floral stem and the branch, respectively, and oviposited on host plants from lineages not expected to express HR in response to pierid eggs. Accordingly, no HR responses were seen. All <em>Pieris</em> eggs found were located on leaves of their host, the only tissue found to express HR-like cell death. Furthermore, each <em>Pieris</em> species was found to at least occasionally oviposit on <em>Brassica nigra</em>. This was the only plant species in this survey that expressed HR-like cell death in response to the eggs of <em>P. rapae, P. napi </em>and <em>P. brassicae</em>. Our observations demonstrate that HR-like cell death remains an effective defence strategy against these <em>Pieris</em> species and as such did not find evidence for the hypothesised counterstrategies. Surveying certain key species and disentangling the micro-evolution of oviposition strategies within a species would allow us to further investigate potential counter-adaptations that evolved against HR-like cell death. This study provides the basis for further investigation of potential counter-adaptations to egg-killing defences.</p>

Data from: A genome-guided strategy for climate resilience in American chestnut restoration populations
<p>The American chestnut (<em>Castanea dentata</em>) is a functionally extinct tree species that was decimated by an invasive fungal pathogen in the early 20<sup>th</sup> century. An understanding of the genomic architecture of local adaptation in wild American chestnut was necessary in order to deploy locally adapted, disease-resistant American chestnut populations. Here, we characterize the genomic basis of climate adaptation in remnant wild American chestnut, develop new computational methods, and evaluate the adaptive genomic content captured within backcross breeding populations. Whole genome re-sequencing data of 356 trees from Sandercock et al. (2022) coupled with genotype-environment association methods identified 18483 climate associated loci.</p>
