Data from: Multilocus coalescent analyses reveal the demographic history and speciation patterns of mouse lemur sister species

Christopher Blair, Kellie L. Heckman, Amy L. Russell & Anne D. Yoder
Background: Debate continues as to whether allopatric speciation or peripatric speciation through a founder effect is the predominant force driving evolution in vertebrates. The mouse lemurs of Madagascar are a system in which evolution has generated a large number of species over a relatively recent time frame. Here, we examine speciation patterns in a pair of sister species of mouse lemur, Microcebus murinus and M. griseorufus. These two species have ranges that are disparately proportioned...

Data from: Brain transcriptional profiles of male alternative reproductive tactics and females in bluegill sunfish

Charlyn G. Partridge, Matthew D. MacManes, Rosemary Knapp & Bryan D. Neff
Bluegill sunfish (Lepomis macrochirus) are one of the classic systems for studying male alternative reproductive tactics (ARTs) in teleost fishes. In this species, there are two distinct life histories: parental and cuckolder, encompassing three reproductive tactics, parental, satellite, and sneaker. The parental life history is fixed, whereas individuals who enter the cuckolder life history transition from sneaker to satellite tactic as they grow. For this study, we used RNAseq to characterize the brain transcriptome of...

Data from: Environmental context and contaminant biotransport by Pacific salmon interact to mediate the bioaccumulation of contaminants by stream-resident fish

Brandon S. Gerig, Dominic T. Chaloner, David J. Janetski, Ashley H. Moerke, Richard R. Rediske, James P. O'Keefe, Dilkushi A. De Alwis Pitts & Gary A. Lamberti
1.The extent to which environmental context mediates the bioaccumulation of biotransported contaminants by stream-resident organisms is poorly understood. For example, it is unclear the extent to which contaminant type, instream characteristics, or resident fish identity interact to influence the uptake of contaminants deposited by Pacific salmon (Oncorhynchus spp.) during their spawning runs. 2.To address this uncertainty, we sampled four stream-resident fish species from 13 watersheds of the Laurentian Great Lakes in locations with and without...

Data from: Long-term population dynamics of dreissenid mussels (Dreissena polymorpha and D. rostriformis): a cross-system analysis

David L. Strayer, Boris V. Adamovich, Rita Adrian, David C. Aldridge, Csilla Balogh, Lyubov E. Burlakova, Hannah B. Fried-Petersen, László G.‐Tóth, Amy L. Hetherington, Thomas S. Jones, Alexander Y. Karatayev, Jacqueline B. Madill, Oleg A. Makarevich, J. Ellen Marsden, Andre L. Martel, Dan Minchin, Thomas F. Nalepa, Ruurd Noordhuis, Timothy J. Robinson, Lars G. Rudstam, Astrid N. Schwalb, David R. Smith, Alan D. Steinman & Jonathan M. Jeschke
Dreissenid mussels (including the zebra mussel Dreissena polymorpha and the quagga mussel D. rostriformis) are among the world's most notorious invasive species, with large and widespread ecological and economic effects. However, their long‐term population dynamics are poorly known, even though these dynamics are critical to determining impacts and effective management. We gathered and analyzed 67 long‐term (>10 yr) data sets on dreissenid populations from lakes and rivers across Europe and North America. We addressed five...

Data from: Low bottleneck detection in long-lived species despite lost genetic diversity: a case study of tuatara and eastern massasauga rattlesnakes

Danielle R. Bradke, Joseph T. Altobelli, Amy L. Russell, Collin P. Jaeger & Jennifer A. Moore
Population bottlenecks can reduce genetic diversity and may lead to inbreeding depression. However, some studies have provided evidence that long lifespans buffer negative genetic effects of bottlenecks. Others have cautioned that longevity might merely mask the effects of genetic drift, which will still affect long-term population viability. We used microsatellite data from actual populations of tuatara (Sphenodon punctatus) and eastern massasaugas (Sistrurus catenatus) as a starting point for simulated population declines to evaluate the performance...

Trap success data for capturing hemlock woolly adelgid

Meg Sanders, Renee Tardani, Kathryn Geller, Alexandra Locher & Charlyn Partridge
Hemlock woolly adelgid (HWA), Adelges tsugae Annand, threatens hemlock forests throughout eastern North America. Management efforts focus on early detection of HWA to ensure rapid management responses to control and stop the spread of this pest. This study’s goal was to identify an affordable, efficient trap to aid with airborne environmental DNA (eDNA) sampling approaches as an early monitoring tool for HWA. We initially compared HWA detection success between a standard sticky trap, commonly used...

Data from: Does local adaptation to resources explain genetic differentiation among Daphnia populations?

Michael Allen, Ryan Thum & Carla Cáceres
Substantial genetic differentiation is frequently observed among populations of cyclically parthenogenetic zooplankton despite their high dispersal capabilities and potential for gene flow. Local adaptation has been invoked to explain population genetic differentiation despite high dispersal, but several neutral models that account for basic life history features also predict high genetic differentiation. Here, we study genetic differentiation among four populations of Daphnia pulex in east central Illinois. As with other studies of Daphnia, we demonstrate substantial...

Data from: Social network analysis of mating patterns in American black bears (Ursus americanus)

Jennifer A. Moore, Ran Xu, Kenneth Frank, Hope Draheim & Kim T. Scribner
Nonrandom mating can structure populations and has important implications for population-level processes. Investigating how and why mating deviates from random is important for understanding evolutionary processes as well as informing conservation and management. Prior to the implementation of parentage analyses, understanding mating patterns in solitary, elusive species like bears was virtually impossible. Here, we capitalize on a long-term genetic data set collected from black bears (Ursus americanus) (N = 2422) in the Northern Lower Peninsula...

Data from: Road avoidance and its energetic consequences for reptiles

James Paterson, James Baxter-Gilbert, Frederic Beaudry, Sue Carstairs, Patricia Chow-Fraser, Christopher Edge, Andrew Lentini, Jacqueline Litzgus, Chantel Markle, Kassie McKeown, Jennifer Moore, Jeanine Refsnider, Julia Riley, Jeremy Rouse, David Seburn, J Zimmerling & Christina Davy
Roads are one of the most widespread human-caused habitat modifications that can increase wildlife mortality rates and alter behaviour. Roads can act as barriers with variable permeability to movement and can increase distances wildlife travel to access habitats. Movement is energetically costly, and avoidance of roads could therefore impact an animal's energy budget. We tested whether reptiles avoid roads or road crossings and explored whether the energetic consequences of road avoidance decreased individual fitness. Using...

Dataset associated with 'Quantification of Ebola virus replication kinetics in vitro'

Laura Liao, Jonathan Carruthers, Sophie J. Smither, , Simon A. Weller, Diane Williamson, Thomas R. Laws, Isabel Garcia-Dorival, Julian Hiscox, Benjamin P. Holder, Catherine Beauchemin, Alan S. Perelson, MARTIN LOPEZ-GARCIA, Grant Lythe, John Barr & carmen molina-parís
This dataset is associated with ‘Quantification of Ebola virus replication kinetics in vitro’. In the paper, a mathematical model is developed to describe the replication of Ebola virus in Vero cells. The model is parametrised using measurements of total and infectious extracellular virus at three different multiplicities of infection. The results provide insights into the distribution of time an infected cell spends in the eclipse phase (the period between infection and the start of virus...

Data from: What smells? Developing in-field methods to characterize the chemical composition of wild mammalian scent cues

Cynthia Thompson
Olfactory cues play an important role in mammalian biology, but have been challenging to assess in the field. Current methods pose problematic issues with sample storage and transportation, limiting our ability to connect chemical variation in scents with relevant ecological and behavioral contexts. Real-time, in-field analysis via portable gas-chromatography mass-spectrometry (GC-MS) has the potential to overcome these issues, but with tradeoffs of reduced sensitivity and compound mass range. We field-tested the ability of portable GC-MS...

Data from: Genetic structure of little brown bats (Myotis lucifugus) corresponds with spread of white-nose syndrome among hibernacula

Cassandra M. Miller-Butterworth, Maarten J. Vonhof, Joel Rosenstern, Gregory G. Turner & Amy L. Russell
Until recently, the little brown bat (Myotis lucifugus) was one of the most common bat species in North America. However, this species currently faces a significant threat from the emerging fungal disease white-nose syndrome (WNS). The aims of this study were to examine the population genetic structure of M. lucifugus hibernating colonies in Pennsylvania (PA) and West Virginia (WV), and to determine whether that population structure may have influenced the pattern of spread of WNS....

Data from: From the field to the lab: best practices for field preservation of bat specimens for molecular analyses

Angelique Corthals, Alynn Martin, Omar M. Warsi, Megan Woller-Skar, Winston Lancaster, Amy Russell & Liliana M. Davalos
Studies in molecular ecology depend on field-collected samples for genetic information, and the tissue sampled and preservation conditions strongly affect the quality of the DNA obtained. DNA yields from different tissue types have seldom been compared, and the relative performance of storage media has never been directly tested, even though these media may influence DNA degradation under field conditions. We analyzed DNA yield from buccal swabs and wing punches harvested from live bats using nucleic...

Transcriptome analysis of invasive Gypsophila paniculata (baby's breath) populations from Michigan and Washington, USA.

Charlyn Partridge, Sarah Lamar & Ian Beddows
Invasive species provide an opportune system to investigate how populations respond to new or changing environments. While the impacts of invasive species increase annually, many gaps in our understanding of how these species invade, adapt, and thrive in the areas they are introduced to remain. Using the perennial forb Gypsophila paniculata as a study system, we aimed to investigate how invasive species respond to different environments. Baby’s breath (Gypsophila paniculata) was introduced to North America...

Genetic diversity and relatedness among African Painted dogs in North America

Cassandra Miller-Butterworth, Karen Vacco, Amy Russell & Joseph Gaspard
African painted dogs (Lycaon pictus, APD) are highly endangered, with fewer than 7,000 remaining in nature. Captive breeding programs can preserve a genetically diverse population and provide a source of individuals for re-introductions. However, most programs are initiated from few founders and suffer from low genetic diversity and inbreeding. The aims of this study were to use molecular markers to assess genetic variation, inbreeding, and relatedness among APDs in the North American captive population, to...

Data from: Geographic variation and environmental correlates of apparent survival rates in adult tree swallows Tachycineta bicolor

Robert G. Clark, David W. Winkler, Russell D. Dawson, Dave Shutler, David J. T. Hussell, Michael P. Lombardo, Patrick A. Thorpe, Peter O. Dunn & Linda A. Whittingham
Determining demographic rates in wild animal populations and understanding why rates vary are important challenges in population ecology and conservation. Whereas reproductive success is reported frequently for many songbird species, there are relatively few corresponding estimates of annual survival for widespread populations of the same migratory species. We incorporated mark-recapture data into Cormack-Jolly-Seber models to estimate annual apparent survival and recapture rates of adult male and female tree swallows Tachycineta bicolor in eight local breeding...

Data from: A coalescent-based estimator of genetic drift, and acoustic divergence in the Pteronotus parnellii species complex

Liliana M Davalos, Winston C Lancaster, Miguel S Nunez Novas, Yolanda M Leon, Bonnie R Lei, Jon Flanders & Amy L Russell
Determining the processes responsible for phenotypic variation is one of the central tasks of evolutionary biology. While the importance of acoustic traits for foraging and communication in echolocating mammals suggests adaptation, the seldom-tested null hypothesis to explain trait divergence is genetic drift. Here we derive FST values from multi-locus coalescent isolation-with-migration models, and couple them with estimates of quantitative trait divergence, or PST, to test drift as the evolutionary process responsible for phenotypic divergence in...

Genetic diversity in two insular populations of bobcats (Lynx rufus)

Duane Diefenbach, Cassandra Miller-Butterworth, Jessie Edson, Leslie Hansen, James Jordan, Tess Gingery & Amy Russell
We documented changes in genetic diversity in an isolated, reintroduced population of bobcats on Cumberland Island (CUIS), Georgia, USA, compared to another bobcat population on Kiawah Island, South Carolina, USA, that was naturally established and experiences limited immigration from the mainland. We compared the predictions of a novel population viability analysis (PVA) to empirical estimates of abundance and genetic diversity on CUIS and used our PVA to identify management actions that are likely to support...
