Graduate students received research assistant support and small summer research grants to support their work in natural resources and conservation biology, as well as plant and soil science. Rachel Moran's dissertation focuses on the importance of male behavior in driving speciation via reinforcement in darters. Rachelhas examined how male mate choice and male-male competition contribute to behavioral isolation and color pattern diversification among species in the orangethroat darter clade Ceasia. This research has also involved determining how genetic divergence and color pattern divergence predict behavioral isolation among species. Another portion of Rachel's research has focused on the importance of reinforcement between the orangethroat darter Etheostoma spectabile and the rainbow darter Etheostoma caeruleum, and the consequences of hybridization in this system. She has found evidence for prezygotic isolation in the form of reproductive and agonistic character displacement in E. spectabile, and postzygotic isolation in the form of hybrid male E. spectabile x E. caeruleum behavioral sterility and backcross inviability. This work has generated two manuscripts and data for at least one more manuscript, as well as several presentations. Additionally, Rachelis working on constructing a linkage map for E. spectabile, which will be used to assist her in assembling the E. spectabile genome. Support for Alida de Flamingh enabled her to complete the DNA genotyping of the elephant fecal samples used to examine the origin and phylogeography of African savannah elephants. This project sought to identify genetic linkages between elephant populations in southern Africa by comparing the elephants in Kruger National Park (South Africa) to populations in nearby countries (Botswana, Mozambique, Zambia and Zimbabwe). This project used mitochondrial and nuclear DNA to investigate phylogenetic relationships, population structure, and gene flow among elephant populations. This work has generated one publication, one presentation, and several manuscripts in preparation. Nicholas Sutton received support for development of a new modeling framework for predicting animal behavior in the presence of high intraspecific behavioral variation (i.e. in the presence of personalities and/or highly habituated/sensitized individuals). The framework also considers predictions under uncertain conditions, where the information for making decisions is imperfect or unknown. This framework was tested in the context of white-tailed deer in relation to visitor pressure in state parks, and will be tested soon with black duck data from collaborators to test in other taxa. This work has generated one publication, and one in preparation, along with a presentation. While supported by Hatch funds, Tyler Refsland finished data collection for two projects included in his dissertation: (1) He sampled tree increment cores that will be used to compare historical drought stress of adult oaks in unburned and 60-year periodically burned forests of Missouri and (2) He collected soil across a range of prescribed fire units that were used as inocculum in a greenhouse experiment that was completed over the summer. This work is investigating the potential for prescribed fire to promote drought resistance of Quercus alba seedlings in a changing climate. Dora Cohen carried out soil microbial ecology work in wetland ecosystems. Restored wetlands sometimes fail to replicate the microbial ecosystem services that occur in natural wetlands, but there is surprisingly little research investigating how restored wetland microbial communities change over time and what that means for ecosystem function. This work found that denitrification rates over time were strongly affected by flood conditions, but the magnitude of response was associated with differences in composition between wetlands, and this response was driven by changes in the relative abundance of specific microbial taxa. This has generated one submitted manuscript, and two additional manuscripts that will be sumbitted soon. Tolulope Perrin-Stowe received funding to support her work in conservation genetics, focusing on mitochondrial function in sterile and fertile inter-species hybrids. She conducted mitogenomic analyses of African elephant lineages to provide insights into the evolutionary history and interactions between the two species, and conductednuclear and mitochondrial examination of a West African population to establish its taxonomic status. Derek Haselhorst was funded to investigate seasonal and long-term phenological and reproductive dynamics in neotropical plant communities using modern pollen trap data. His research builds on a phenological analysis on the effect of seasonal and long-term climatic variability on Neotropical flowering phenology (completed for his first dissertation chapter). This research incorporated pollen trap data collected from canopy canes located in two lowland Panamanian forests characterized by differences in mean annual rainfall and seasonality - Barro Colorado Island (BCI) and Parque National San Lorenzo (PSNL). The black-legged tick (Ixodes scapularis) is responsible for transmitting the Lyme disease pathogen (Borrelia burgdorferi) to humans. Since the 1970's, the geographic distributions of both the pathogen and the black-legged tick have expanded throughout the U.S. This expansion is thought to be primarily due to highly mobile wildlife hosts such as migratory birds and deer, although the relative contribution of each host has yet to be quantified. Sam Halsey was supported by Hatch funding to carry out research to advance our understanding of the mechanisms involved in the invasion and establishment of I. scapularis and B. burgdorferi by utilizing a community framework via individual-based modelling. Selina Ruzi was supported to carry out work to investigate the identity of ants involved in seed dispersal of non-myrmecochorous plants, and determine the chemical mechanism responsible for ant-mediated seed dispersal to link a mechanistic process to community-wide patterns of plant dispersal and establishment. The questions she addressed included: (1) Does variation in local ant communities correlate with the observed variation in seed removal rates at different locations within a single forest? and (2) Do non-myrmeocochorous plants mimic the chemical cues present on insects to elicit the seed-carrying response in ants? The successful recruitment of new individuals into a population depends on being able to navigate a variety of obstacles that can ultimately influence community structure. Plants, for example, are limited by the number of seeds they produce, if their seeds survive dispersal events, and whether those seeds reach suitable microsites for germination/establishment. Ultimately, identifying the mechanisms responsible for successful dispersal is key for understanding the structure and stability of plant communities. N2O flux from low-lying areas that are typically hotspots of N2O flux can be inhibited following large rain events, while N2O flux may dramatically increase in the rest of the field. Different areas of the field can act as hotspots of N2O flux depending on environmental conditions. Alex Krichels was supported by Hatch funds to conduct research to increase our understanding of the spatial and temporal controls on the location and magnitude of hotspots of N2O flux is an important step in improving models of N2O emissions. To better understand these controls, he investigated the following questions: (1) What spatial factors control where hotspots of N2O emissions occur under different environmental conditionsand (2) How do hotspots affect estimates of cumulative N2O emissions from a field? His work included field measures of N2O fluxes, soil biogeochemistry approaches, DNA sequencing and qPCR to characterize microbes involved in these processes, and modeling.

This work is being preparedfor submission to PNAS. Alyssa Beckwas supported to conducta greenhouse experiment to examine the influence of Lespedeza cuneata root exudates and leaf litter leachates on microbial community assembly and plant-soil feedbacks, as part of an ongoing study onthe effect of plant invasions on soil microbial communities. A manuscript is being generated to report findings from this study.

Philippe Doucet Beaupré was funded to carry out studies in support of his dissertation work on phylodynamic modeling and robust inference of diversification processes in microbial communities. For this work, heappliedthe phylodynamic maximum likelihood algorithm he developed during the past year to the 15,000 individual environmental samples found in the Earth Microbiome Project dataset and to further the analysis of the angiosperm, marine, phylosphere, gut, and skin samples used in previouswork. The inference will allow him to separate the contribution of neutral and innovation processes to the dynamic of diversification across similar and different habitats and biomes, abiotic variables, and geographic locations. Miles Bensky was funded to continue his work in animal behavior and conservation. His work includes gathering evidence for cognitive trade-offs usingthree-spined sticklebacks as a model system. His disseration topic is:Measuring the molecular and ecological mechanisms driving differences in learning flexibility in threespined stickleback, where the overall goal is to identify the ecological and molecular causes of variation in learning flexibility in sticklebacks.
