Data from: A spatial genetics approach to inform vector control of tsetse flies (Glossina fuscipes fuscipes) in Northern Uganda

Norah Saarman, Mary Burak, Robert Opiro, Chaz Hyseni, Richard Echodu, Kirstin Dion, Elizabeth A. Opiyo, Augustine W. Dunn, Giuseppe Amatulli, Serap Aksoy & Adalgisa Caccone
Tsetse flies (genus Glossina) are the only vector for the parasitic trypanosomes responsible for sleeping sickness and nagana across sub-Saharan Africa. In Uganda, the tsetse fly Glossina fuscipes fuscipes is responsible for transmission of the parasite in 90% of sleeping sickness cases, and co-occurrence of both forms of human-infective trypanosomes makes vector control a priority. We use population genetic data from 38 samples from northern Uganda in a novel methodological pipeline that integrates genetic data,...

Data from: Is it the song or the singers? Acoustic and social experiences shape adult reproductive tactics and condition

Susan L. Balenger, Elizabeth Bastiaans & Marlene Zuk
When sexual signals are perceived during growth and development they can provide information regarding the social conditions likely to be encountered as an adult. Perception of cues related to the presence and density of future mates and potential competitors can result in altered adult phenotypes. Previous studies have shown that adult male Teleogryllus oceanicus field crickets from a Kauai, Hawaii population reared alone and without hearing conspecific song are more phonotactic than those reared with...

Data from: Genetically determined fungal pathogen tolerance and soil variation influences ectomycorrhizal traits of loblolly pine

Bridget J. Piculell, Lori G. Eckhardt & Jason D. Hoeksema
1. Selection on genetically correlated traits within species can create indirect effects on one trait by selection on another. The consequences of these trait correlations are of interest because they may influence how suites of traits within species evolve under differing selection pressures, both natural and artificial. 2. By utilizing genetic families of loblolly pine either tolerant (t) or susceptible (s) to two different suites of pathogenic fungi responsible for causing either pine decline (PD)...

Data from: The population genomics of multiple tsetse fly (Glossina fuscipes fuscipes) admixture zones in Uganda

Norah P. Saarman, Robert Opiro, Chaz Hyseni, Richard Echodu, Elizabeth A. Opiyo, Kirstin Dion, Thomas Johnson, Serap Aksoy & Adalgisa Caccone
Understanding the mechanisms that enforce, maintain, or reverse the process of speciation is an important challenge in evolutionary biology. This study investigates the patterns of divergence and discusses the processes that form and maintain divergent lineages of the tsetse fly Glossina fuscipes fuscipes in Uganda. We sampled 251 flies from 18 sites spanning known genetic lineages and the four admixture zones between them. We apply population genomics, hybrid zone, and approximate Bayesian computation to the...

Data from: Colonization across gradients of risk and reward: nutrients and predators generate species-specific responses among aquatic insects

Matthew R. Pintar, Jason R. Bohenek, Lauren L. Eveland & William J. Resetarits
1. Predation risk and resource abundance are two primary characteristics that determine species abundances and community composition. Colonizing organisms should attempt to minimize the risk of mortality and maximize growth through selection of patches with the highest expected fitness. However, maximizing fitness across multiple gradients of patch quality involves accurate cue assessment, integration, and behavioral responses that consider multiple factors that affect fitness simultaneously. 2. Our goal was to simultaneously and factorially assess the effects...

Data from: Bidirectionality of hormone-behavior relationships and satellite-caller dynamics in green treefrogs

Sarah P. Crocker-Buta & Christopher J. Leary
Whether hormonal differences among males that conditionally alternate between mating tactics are a cause or consequence of behavioral expression is central to understanding the mechanisms regulating alternative mating tactics. This issue is rooted in the bidirectionality of hormone-behavior relationships and is particularly relevant to alternative mating tactics in anuran amphibians because the social-acoustic environment can mediate changes in both tactic expression and hormone levels. Hence, it is not clear whether males adopt different mating tactics...

Data from: A prospective study of serum metabolites and risk of ischemic stroke

Daokun Sun, Steffen Tiedt, Bing Yu, Xueqiu Jian, Rebecca F. Gottesman, Tom H. Mosley, Eric Boerwinkle, Martin Dichgans & Myriam Fornage
Objective: To identify promising blood-based biomarkers and novel etiological pathways of disease risk, we applied an untargeted serum metabolomics profiling in a community-based prospective study of ischemic stroke (IS). Methods: In 3,904 men and women from the Atherosclerosis Risk In Communities (ARIC) study, Cox proportional hazard models were used to estimate the association of incident IS with the standardized level of 245 fasting serum metabolites individually, adjusting for age, sex, race, field center, batch, diabetes,...

Data from: Population genomics through time provides insights into the consequences of decline and rapid demographic recovery through head-starting in a Galapagos giant tortoise

Evelyn L. Jensen, Danielle L. Edwards, Ryan C. Garrick, Joshua M. Miller, James P. Gibbs, Linda J. Cayot, Washington Tapia, Aldalgisa Caccone, Michael A. Russello & Adalgisa Caccone
Population genetic theory related to the consequences of rapid population decline is well-developed, but there are very few empirical studies where sampling was conducted before and after a known bottleneck event. Such knowledge is of particular importance for species restoration, given links between genetic diversity and the probability of long-term persistence. To directly evaluate the relationship between current genetic diversity and past demographic events, we collected genome-wide single nucleotide polymorphism data from pre-bottleneck historical (c.1906)...

Data from: Extending phylogeography to account for lineage fusion

Ryan C. Garrick, John D. Banusiewicz, Stephanie Burgess, Chaz Hyseni & Rebecca E. Symula
Secondary contact between long isolated populations has several possible outcomes. These include the strengthening of preexisting reproductive isolating mechanisms via reinforcement, the emergence of a hybrid lineage that is distinct from its extant parental lineages and which occupies a spatially restricted zone between them, or complete merging of two populations such that parental lineages are no longer extant ("lineage fusion" herein). The latter scenario has rarely been explicitly considered in single-species and comparative phylogeographic studies,...

Data from: Association mapping of ectomycorrhizal traits in loblolly pine (Pinus taeda L.)

Bridget J. Piculell, Pedro José Martínez-García, C. Dana Nelson & Jason D. Hoeksema
To understand how diverse mutualisms coevolve and how species adapt to complex environments, a description of the underlying genetic basis of the traits involved must be provided. For example, in diverse coevolving mutualisms, such as the interaction of host plants with a suite of symbiotic mycorrhizal fungi, a key question is whether host plants can coevolve independently with multiple species of symbionts, which depends on whether those interactions are governed independently by separate genes or...

Data from: Rapid effects of elevated stress hormones on male courtship signals suggest a major role for the acute stress response in intra- and intersexual selection

Christopher J. Leary & Sarah Crocker-Buta
1. Short-term elevations in circulating stress hormones (glucocorticoids) often mediate reduced investment in reproductive behavior in favor of self-maintenance and survival, but the significance of these effects in sexual selection and communication remain largely unexplored. 2. Here we examine the acute stress response in the context of intra- and intersexual selection in the green treefrog, Hyla cinerea. Males of this species produce agonistic acoustic signals that stimulate elevations in the stress hormone corticosterone (CORT) in...
