Data from: What can aquatic gastropods tell us about phenotypic plasticity? A review and meta-analysis

Paul E. Bourdeau, Roger K. Butlin, Christer Brönmark, Timothy C. Edgell, Jason T. Hoverman & Johan Hollander
There have been few attempts to synthesise the growing body of literature on phenotypic plasticity to reveal patterns and generalities about the extent and magnitude of plastic responses. Here, we conduct a review and meta-analysis of published literature on phenotypic plasticity in aquatic (marine and freshwater) gastropods, a common system for studying plasticity. We identified 96 studies, using pre-determined search terms, published between 1985 and November 2013. The literature was dominated by studies of predator-induced...

Data from: The contribution of phenotypic plasticity to the evolution of insecticide tolerance in amphibian populations

Jessica Hua, Devin K. Jones, Brian M. Mattes, Rickey D. Cothran, Rick A. Relyea & Jason T. Hoverman
Understanding population responses to rapid environmental changes caused by anthropogenic activities, such as pesticides, is a research frontier. Genetic assimilation (GA), a process initiated by phenotypic plasticity, is one mechanism potentially influencing evolutionary responses to novel environments. While theoretical and laboratory research suggests that GA has the potential to influence evolutionary trajectories, few studies have assessed its role in the evolution of wild populations experiencing novel environments. Using the insecticide, carbaryl, and 15 wood frog...

Data from: Mate competition and evolutionary outcomes in genetically modified Zebrafish (Danio rerio)

Richard D. Howard, Karl Rohrer, Yiyang Liu & William M. Muir
Demonstrating relationships between sexual selection mechanisms and trait evolution is central to testing evolutionary theory. Using zebrafish, we found that wild-type males possessed a significant advantage in mate competition over transgenic RFP Glofish™ males. In mating trials, wild-type males were aggressively superior to transgenic males in male-male chases and male-female chases; as a result, wild-type males sired 2.5x as many young as did transgenic males. In contrast, an earlier study demonstrated that female zebrafish preferred...

Data from: Prey responses to fine-scale variation in predation risk from combined predators

Jason T. Hoverman & Rick A. Relyea
While it is well documented that organisms can express phenotypic plasticity in response to single gradients of environmental variation, our understanding of how organisms integrate information along multiple environmental gradients is limited in many systems. Using the freshwater snail Helisoma trivolvis and two common predators (water bugs Belostoma flumineum and crayfish Orconectes rusticus), we explored how prey integrate information along multiple predation risk gradients (i.e. caged predators fed increasing amounts of prey biomass) that induce...

Data from: Ontogenetic changes in embryonic and brain gene expression in progeny produced from migratory and resident Oncorhynchus mykiss

Garrett J. McKinney, Matthew C. Hale, Giles Goetz, Michael Gribskov, Frank P. Thrower & Krista M. Nichols
Little information has been gathered regarding the ontogenetic changes that contribute to differentiation between resident and migrant individuals, particularly before the onset of gross morphological and physiological changes in migratory individuals. The aim of this study was to evaluate gene expression during early development in Oncorhynchus mykiss populations with different life histories, in a tissue known to integrate environmental cues to regulate complex developmental processes and behaviours. We sampled offspring produced from migrant and resident...

Data from: Assessing the permeability of landscape features to animal movement: using genetic structure to infer functional connectivity

Sara J. Anderson, Elizabeth M. Kierepka, Robert K. Swihart, Emily K. Latch, & Olin E. Rhodes
Human-altered environments often challenge native species with a complex spatial distribution of resources. Hostile landscape features can inhibit animal movement (i.e., genetic exchange), while other landscape attributes facilitate gene flow. The genetic attributes of organisms inhabiting such complex environments can reveal the legacy of their movements through the landscape. Thus, by evaluating landscape attributes within the context of genetic connectivity of organisms within the landscape, we can elucidate how a species has coped with the...

Data from: Immunomics of the koala (Phascolarctos cinereus )

Kendra C. Abts, Jamie A. Ivy & J. Andrew DeWoody
The study of the koala transcriptome has the potential to advance our understanding of its immunome—immunological reaction of a given host to foreign antigens—and to help combat infectious diseases (e.g., chlamydiosis) that impede ongoing conservation efforts. We used Illumina sequencing of cDNA to characterize genes expressed in two different koala tissues of immunological importance, blood and spleen. We generated nearly 600 million raw sequence reads, and about 285 million of these were subsequently assembled and...

Data from: Plant-soil interactions shape the identity and persistence of soil organic carbon in invaded ecosystems: implication for legacy effects

Vidya Suseela, Peter Alpert, Cindy H. Nakatsu, Arthur Armstrong & Nishanth Tharayil
1. Introduced, invasive plants can alter local soil chemistry and microbial communities, but the underlying mechanisms and extent of these changes are largely unknown. Based on characteristics associated with invasiveness in plants, it was hypothesized that introduced species that produce large amounts of litter with distinctive secondary compounds can a) alter the chemistry of both extractable and bulk carbon in the soil, b) shift microbial communities towards microbes better able to metabolize the compounds in...

Data from: Revisiting the Iberian honey bee (Apis mellifera iberiensis) contact zone: maternal and genome-wide nuclear variation provide support for secondary contact from historical refugia

M. Alice Pinto, Julio C. Chávez-Galarza, Dora Henriques, J. Spencer Johnston, Miguel Carneiro, José Rufino & John C. Patton
Dissecting diversity patterns of organisms endemic to Iberia has been truly challenging for a variety of taxa, and the Iberian honey bee is no exception. Surveys of genetic variation in the Iberian honey bee are among the most extensive for any honey bee subspecies. From these, differential and complex patterns of diversity have emerged, which have yet to be fully resolved. Here, we used a genome-wide data set of 309 neutrally tested single nucleotide polymorphisms...

Data from: Habitat corridors facilitate genetic resilience irrespective of species dispersal abilities or population sizes

Mark R. Christie & L. Lacey Knowles
Corridors are frequently proposed to connect patches of habitat that have become isolated due to human-mediated alterations to the landscape. While it is understood that corridors can facilitate dispersal between patches, it remains unknown whether corridors can mitigate the negative genetic effects for entire communities modified by habitat fragmentation. These negative genetic effects, which include reduced genetic diversity, limit the potential for populations to respond to selective agents such as disease epidemics and global climate...

Data from: The cacao pathogen Moniliophthora roreri (Marasmiaceae) possesses biallelic A and B mating loci but reproduces clonally

Jorge R. Díaz-Valderrama & M. Catherine Aime
The cacao pathogen Moniliophthora roreri belongs to the mushroom-forming family Marasmiaceae, but it has never been observed to produce a fruiting body, which calls to question its capacity for sexual reproduction. In this study, we identified potential A (HD1 and HD2) and B (pheromone precursors and pheromone receptors) mating genes in M. roreri. A PCR-based method was subsequently devised to determine the mating type for a set of 47 isolates from across the geographic range...

Data from: Genetic architecture, biochemical underpinnings, and ecological impact of floral UV patterning

Marcus Brock, Lauren Lucas, Nickolas A. Anderson, Matthew Rubin, R. J. Markelz, Michael Covington, Upendra Devisetty, Clint Chapple, Julin Maloof, Cynthia Weinig, Lauren K. Lucas, Marcus T. Brock, Matthew J. Rubin, R. J. Cody Markelz, Michael F. Covington, Upendra K. Devisetty & Julin N. Maloof
Floral attraction traits can significantly affect pollinator visitation patterns, but adaptive evolution of these traits may be constrained by correlations with other traits. In some cases, molecular pathways contributing to floral attraction are well-characterized, offering the opportunity to explore loci potentially underlying variation among individuals. Here, we quantify the range of variation in floral UV patterning (i.e., UV “bulls-eye” nectar guides) among crop and wild accessions of Brassica rapa. We then use experimental crosses to...

Data from: Evolution of novel wood decay mechanisms in Agaricales revealed by the genome sequences of Fistulina hepatica and Cylindrobasidium torrendii

Dimitrios Floudas, Benjamin W. Held, Robert Riley, Laszlo G. Nagy, Gage Koehler, Anthony S. Ransdell, Hina Younus, Julianna Chow, Jennifer Chiniquy, Anna Lipzen, Andrew Tritt, Hui Sun, Sajeet Haridas, Kurt LaButti, Robin A. Ohm, Ursula Kues, Robert A. Blanchette, Igor V. Grigoriev, Robert E. Minto & David S. Hibbett
Wood decay mechanisms in Agaricomycotina have been traditionally separated in two categories termed white and brown rot. Recently the accuracy of such a dichotomy has been questioned. Here, we present the genome sequences of the white rot fungus Cylindrobasidium torrendii and the brown rot fungus Fistulina hepatica both members of Agaricales, combining comparative genomics and wood decay experiments. Cylindrobasidium torrendii is closely related to the white-rot root pathogen Armillaria mellea, while F. hepatica is related...
