Data from: Genetic data reveal mixed-stock aggregations of gray whales in the North Pacific Ocean

Anna Brüniche-Olsen, R. Jorge Urban, Vladimir V. Vertyankin, Celine A.J. Godard-Codding, John W. Bickham & J. Andrew DeWoody
Gray whales (Eschrichtius robustus) in the Western Pacific are critically endangered whereas in the Eastern Pacific they are relatively common. Holocene environmental changes and commercial whaling reduced their numbers, but gray whales in the Eastern Pacific now outnumber their Western counterparts by more than 100-fold. Herein, we investigate the genetic diversity and population structure within the species using a panel of genic SNPs. Results indicate the gray whale gene pool is differentiated into two substocks...

Data from: Schlieren photography on freely flying hawkmoth

Yun Liu, Jesse Roll, Stephen Van Kooten & Xinyan Deng
The aerodynamic force on flying insects result from the vortical flow structures that vary both spatially and temporally throughout flight. Due to these complexities and the inherent difficulties in studying flying insects in a natural setting, a complete picture of the vortical flow has been difficult to obtain experimentally. In this paper, Schlieren, a widely used technique for highspeed flow visualization, was adapted to capture the vortex structures around freely flying hawkmoth (Manduca). Flow features...

Data from: Phylogenetic patterns of trait and trait plasticity evolution: Insights from amphibian embryos

Rick Relyea, Patrick R. Stephens, Lisa N. Barrow, Andrew Blaustein, Paul Bradley, Julia Buck, Ann Chang, Brian I Crother, James Collins, Julia Earl, Stephanie S. Gervasi, Jason T. Hoverman, Olliver Hyman, Emily Claire Moriarty Lemmon, Thomas Luhring, Moses Michelsohn, Christopher M. Murray, Steven Price, Raymond Semlitsch, Andy Sih, Aaron Stoler, Nick VandenBroek, Alexa Warwick, Greta Wengert, John Hammond … & Aaron B. Stoler
Environmental variation favors the evolution of phenotypic plasticity. For many species, we understand the costs and benefits of different phenotypes, but we lack a broad understanding of how plastic traits evolve across large clades. Using identical experiments conducted across North America, we examined prey responses to predator cues. We quantified five life history traits and the magnitude of their plasticity for 23 amphibian species/populations (spanning three families and five genera) when exposed to no cues,...

Data from: Resurrected “ancient” Daphnia genotypes show reduced thermal stress tolerance compared to modern descendants

Aimee M. Yousey, Priyanka Roy Chowdhury, Nicole Biddinger, Jennifer H. Shaw, Punidan D. Jeyasingh, Lawrence J. Weider & Aime'e M. Yousey
Understanding how populations adapt to rising temperatures has been a challenge in ecology. Research often evaluates multiple populations to test whether local adaptation to temperature regimes is occurring. Space-for-time substitutions are common, as temporal constraints limit our ability to observe evolutionary responses. We employed a resurrection ecology approach to understand how thermal tolerance has changed in a Daphnia pulicaria population over time. Temperatures experienced by the oldest genotypes were considerably lower than the youngest. We...

Data from: Demographic, environmental and genetic determinants of mating success in captive koalas (Phascolarctos cinereus)

Kendra C. Abts, Jamie A. Ivy & J. Andrew DeWoody
Many factors have been shown to affect mating behavior. For instance, genes of the major histocompatibility complex (MHC) are known to influence mate choice in a wide variety of vertebrate species. The genetic management of captive populations can be confounded if intrinsic mate choice reduces or eliminates reproductive success between carefully chosen breeding pairs. For example, the San Diego Zoo koala colony only has a 45% copulation rate for matched individuals. Herein, we investigated determinants...

Data from: Using host-associated differentiation to track source population and dispersal distance among insect vectors of plant pathogens

Gina M. Angelella, Andy P. Michel, Ian Kaplan, G.M. Angelella & A.P. Michel
Small, mobile insects are notoriously challenging to track across landscapes and manage in agricultural fields. However, genetic differentiation among insect populations and host-plants acquired through host-associated differentiation could be exploited to infer movement within crop systems and damage potential. Although many insects exhibit host-associated differentiation, management strategies for insect vectors of plant pathogens assume a homogenous population. Nevertheless, phenotypic changes derived from host-associated differentiation could manifest in altered behavior or physiology affecting the likelihood of...

Data from: Differential processing of nociceptive input within upper limb muscles

Nathanial R. Eckert, Brach Poston & Zachary A. Riley
The cutaneous silent period is an inhibitory evoked response that demonstrates a wide variety of responses in muscles of the human upper limb. Classically, the cutaneous silent period results in a characteristic muscle pattern of extensor inhibition and flexor facilitation within the upper limb, in the presence of nociceptive input. The aims of the current study were: 1) to primarily investigate the presence and characteristics of the cutaneous silent period response across multiple extensor and...

Data from: Temporal transcriptional logic of dynamic regulatory networks underlying nitrogen signaling and use in plants

Kranthi Varala, Amy Marshall-Colón, Jacopo Cirrone, Matthew D. Brooks, Angelo V. Pasquino, Sophie Léran, Shipra Mittal, Tara M. Rock, Molly B. Edwards, Grace J. Kim, Sandrine Ruffel, W. Richard McCombie, Dennis Shasha & Gloria M. Coruzzi
This study exploits time, the relatively unexplored fourth dimension of gene regulatory networks (GRNs), to learn the temporal transcriptional logic underlying dynamic nitrogen (N) signaling in plants. Our “just-in-time” analysis of time-series transcriptome data uncovered a temporal cascade of cis elements underlying dynamic N signaling. To infer transcription factor (TF)-target edges in a GRN, we applied a time-based machine learning method to 2,174 dynamic N-responsive genes. We experimentally determined a network precision cutoff, using TF-regulated...

Data from: Influence of immunogenetics, sex, and body condition on the cutaneous microbial communities of two giant salamanders

Obed Hernandez-Gomez, Jeffrey T. Briggler & Rod N. Williams
The complex association between hosts and microbial symbionts requires the implementation of multiple approaches to evaluate variation in host physiology. Within amphibians, heterogeneity in immunogenetic traits and cutaneous microbiota is associated with variation in disease resistance. Ozark (Cryptobranchus alleganiensis bishopi) and eastern hellbenders (C. a. alleganiensis) provide a model system to assess variation in host traits and microbial communities. Ozark hellbenders have experienced declines throughout their range, are federally endangered, and experience wound retardation that...

Data from: Anuran predators overcome visual illusion: dazzle coloration does not protect moving prey

Sara Zlotnik, Geena M. Darnell & Ximena E. Bernal
Predators everywhere impose strong selection pressures on the morphology and behavior of their prey, but the resulting antipredator adaptations vary greatly among species. Studies of adaptive coloration in prey species have generally focused on cryptic or aposematic prey, with little consideration of color patterns in palatable mobile prey. Complex color patterns have been proposed to decrease the ability of visual predators to capture moving prey (motion dazzle effect). Most support for this hypothesis, however, comes...

Data from: Adult experts’ perceptions of telemental health for youth: a Delphi study

Abigail Howard, Mindy Flanagan, Michelle Drouin, Maria Carpenter, Elizabeth M. Chen, Catherine Duchovic & Tammy Toscos
Objectives: Our objectives were to measure experts’ opinions and develop consensus via the Delphi process on the barriers, applications, and concerns associated with telemental health (TMH) for youth. Materials and methods: We delivered 3 online surveys over 2 months in Summer, 2016–2025 adult experts, including adults who experienced youth depression or suicidality, parents of youth with lived experience, and professionals (ie youth mental health researchers, clinicians/staff, or educators). We used the Delphi method to construct...

Data from: Population structure of Guyanagaster necrorhizus supports termite dispersal for this enigmatic fungus

Rachel A. Koch & Mary Catherine Aime
Understanding dispersal mechanisms—the movement of propagules—can shed light on how organisms are adapted for their ecosystem. Guyanagaster necrorhizus is a sequestrate fungus, meaning its dispersal propagules, or spores, are entirely enclosed within a fruiting body, termed a sporocarp. This fungus is most closely related to Armillaria and its allies. While Armillaria species form mushrooms with forcibly discharged spores, G. necrorhizus spores have lost this ability, and by necessity, must be passively dispersed. However, G. necrorhizus...

Data from: Large ecosystem service benefits of assisted natural regeneration

Yusheng Yang, Lixin Wang, Zhijie Yang, Chao Xu, Jingsheng Xie, Guangshui Chen, Chengfang Lin, Jianfen Guo, Xiaofei Liu, Decheng Xiong, Weisheng Lin, Shidong Chen, Zongming He, Kaimiao Lin, Miaohua Jiang & Teng-Chiu Lin
China manages the largest monoculture plantations in the world, with 24% being Chinese fir plantations. Maximizing the ecosystem services of Chinese fir plantations has important implications in global carbon cycle and biodiversity protection. Assisted natural regeneration (ANR) is a practice to convert degraded lands into more productive forests with great ecosystems services. However, the quantitative understanding of ANR ecosystem service benefits is very limited. We conducted a comprehensive field manipulation experiment to evaluate the ANR...

Data from: Mate choice in the eye and ear of the beholder? Female multimodal sensory configuration influences her preferences

Kelly Ronald, Esteban Fernandez-Juricic, Jeffrey Lucas, Jeffrey R. Lucas & Kelly L. Ronald
A common assumption in sexual selection studies is that receivers decode signal information similarly. However, receivers may vary in how they rank signallers if signal perception varies with an individual’s sensory configuration. Furthermore, receivers may vary in their weighting of different elements of multimodal signals based on their sensory configuration. This could lead to complex levels of selection on signalling traits. We tested whether multimodal sensory configuration could affect preferences for multimodal signals. We used...

Data from: Of poisons and parasites: the defensive role of tetrodotoxin against infections in newts

Pieter T. J. Johnson, Dana M. Calhoun, Amber N. Stokes, Calvin B. Susbilla, Travis McDevitt-Galles, Cheryl J. Briggs, Jason T. Hoverman, Vasyl V. Tkach, Jaap C. De Roode & Jacobus C. De Roode
1. Classical research on animal toxicity has focused on the role of toxins in protection against predators, but recent studies suggest these same compounds can offer a powerful defense against parasites and infectious diseases. 2. Newts in the genus Taricha are brightly colored and contain the potent neurotoxin, tetrodotoxin (TTX), which is hypothesized to have evolved as a defense against vertebrate predators such as garter snakes. However, newt populations often vary dramatically in toxicity, which...

Data from: Whole genome sequence accuracy is improved by replication in a population of mutagenized sorghum.

Charles Addo-Quaye, Mitch Tuinstra, Nicola Carraro, Clifford Weil & Brian P. Dilkes
The accurate detection of induced mutations is critical for both forward and reverse genetics studies. Experimental chemical mutagenesis induces relatively few single base changes per individual. In a complex eukaryotic genome, false positive detection of mutations can occur at or above this mutagenesis rate. We demonstrate here, using a population of ethyl methanesulfonate (EMS) treated Sorghum bicolor BTx623 individuals, that using replication to detect false positive induced variants in next-generation sequencing data permits higher throughput...

Data from: New insights into the phylogenetics and population structure of the prairie falcon (Falco mexicanus)

Jacqueline M. Doyle, Douglas A. Bell, Peter H. Bloom, Gavin Emmons, Amy Fesnock, Todd E. Katzner, Larry LaPré, Kolbe Leonard, Phillip SanMiguel, Rick Westerman & J. Andrew DeWoody
Background: Management requires a robust understanding of between- and within-species genetic variability, however such data are still lacking in many species. For example, although multiple population genetics studies of the peregrine falcon (Falco peregrinus) have been conducted, no similar studies have been done of the closely-related prairie falcon (F. mexicanus) and it is unclear how much genetic variation and population structure exists across the species’ range. Furthermore, the phylogenetic relationship of F. mexicanus relative to...

Data from: Spatiotemporal distribution and environmental drivers of Barley yellow dwarf virus and vector abundance in Kansas

Laramy S. Enders, Trevor J. Hefley, John J. Girvin, Robert J. Whitworth & Charles M. Smith
Several aphid species transmit barley yellow dwarf, a globally destructive disease caused by viruses that infect cereal grain crops. Data from >400 samples collected across Kansas wheat fields in 2014 and 2015 were used to develop spatio-temporal models predicting the extent to which landcover, temperature and precipitation affect spring aphid vector abundance and presence of individuals carrying Barley yellow dwarf virus (BYDV). The distribution of Rhopalosiphum padi abundance was not correlated with climate or landcover,...

Data from: Phylogenomics and the evolution of hemipteroid insects

Kevin P. Johnson, Christopher H. Dietrich, Frank Friedrich, Rolf G. Beutel, Benjamin Wipfler, Ralph S. Peters, Julie M. Allen, Malte Petersen, Alexander Donath, Kimberly K. O. Walden, Alexey M. Kozlov, Lars Podsiadlowski, Christoph Mayer, Karen Meusemann, Alexandros Vasilikopoulos, Robert M. Waterhouse, Stephen L. Cameron, Christiane Weirauch, Daniel R. Swanson, Diana M. Percy, Nate B. Hardy, Irene Terry, Shanlin Liu, Xin Zhou, Bernhard Misof … & Kazunori Yoshizawa
Hemipteroid insects (Paraneoptera), with over 10% of all known insect diversity, are a major component of terrestrial and aquatic ecosystems. Previous phylogenetic analyses have not consistently resolved the relationships among major hemipteroid lineages. We provide maximum likelihood-based phylogenomic analyses of a taxonomically comprehensive dataset comprising sequences of 2,395 single-copy, protein-coding genes for 193 samples of hemipteroid insects and outgroups. These analyses yield a well-supported phylogeny for hemipteroid insects. Monophyly of each of the three hemipteroid...

Data from: Cascading effects of forested area and isolation on seed dispersal effectiveness of rodents on subtropical islands

Di Zeng, Robert K. Swihart, Yuhao Zhao, Xingfeng Si & Ping Ding
1. Habitat loss and fragmentation often leads to defaunation of large-bodied mammals, and their loss could trigger release from top-down control or food resource competition for small mammal seed dispersers, which in turn may affect the effectiveness of seed dispersal by altering the number of dispersed seeds or the manner in which they are dispersed. Although rodents are primary seed dispersers in habitat subjected to defaunation, changes in seed dispersal effectiveness of rodents along mammalian...
