Echinoderm sperm swimming and fertilization

Mike Nishizaki, Sara Leuchtenberger, Maris Daleo, Peter Gullickson, Andi Delgado & Carly Lo
In an era of climate change, impacts on the marine environment include warming and ocean acidification. These effects can be amplified in shallow coastal regions where conditions often fluctuate widely. This type of environmental variation is potentially important for many nearshore species that are broadcast spawners, releasing eggs and sperm into the water column for fertilization. We conducted two experiments to investigate: 1) the impact of water temperature on sperm swimming characteristics and fertilization rate...

Data from: Evaluating temporal and spatial transferability of a tidal inundation model for foraging waterbirds

Marisa Martinez, Leonardo Calle, Stephanie Romanach & Dale Gawlik
For ecosystem models to be applicable outside their context of development, temporal and spatial transferability must be demonstrated. This presents a challenge for modeling intertidal ecosystems where spatiotemporal variation arises at multiple scales. Models specializing in tidal dynamics are generally inhibited from having wider ecological applications by coarse spatiotemporal resolution or high user competency. The Tidal Inundation Model of Shallow-water Availability (TiMSA) uniquely simulates tides to empirically derive a time-integrated measure of availability for a...

Small, odd and old: The mysterious Tarsius pumilus is the most basal Sulawesi tarsier

Laura Hagemann, Nanda Grow, Yvonne Bohr, Dyah Perwitasari-Farajallah, Yulius Duma, Sharon Gursky & Stefan Merker
In this study we present the first genetic evidence of the phylogenetic position of Tarsius pumilus, the mountain tarsier of Sulawesi, Indonesia. This mysterious primate is the only Eastern tarsier species that occurs exclusively in cloud forests above 1800 m asl. It exhibits striking morphological peculiarities – most prominently its extremely reduced body size, which led to the common name of “pygmy tarsier”. However, our results indicate that T. pumilus is not an aberrant form...

Data from: Network analysis of sea turtle movements and connectivity: a tool for conservation prioritization

Connie Y. Kot, Susanne Åkesson, Joanna Alfaro-Shigueto, Diego Fernando Amorocho Llanos, Marina Antonopoulou, George H. Balazs, Warren R. Baverstock, Janice M. Blumenthal, Annette C. Broderick, Ignacio Bruno, Ali Fuat Canbolat, Paolo Casale, Daniel Cejudo, Michael S. Coyne, Corrie Curtice, Sarah DeLand, Andrew DiMatteo, Kara Dodge, Daniel C. Dunn, Nicole Esteban, Angela Formia, Mariana M. P. B. Fuentes, Ei Fujioka, Julie Garnier, Matthew H. Godfrey … & Patrick N. Halpin
Aim: Understanding the spatial ecology of animal movements is a critical element in conserving long-lived, highly mobile marine species. Analysing networks developed from movements of six sea turtle species reveals marine connectivity and can help prioritize conservation efforts. Location: Global. Methods: We collated telemetry data from 1,235 individuals and reviewed the literature to determine our dataset’s representativeness. We used the telemetry data to develop spatial networks at different scales to examine areas, connections, and their...

Population structure, patterns of natal dispersal, and demographic history in a declining aerial insectivore, the purple martin Progne subis

Evelien De Greef, Wesley Brashear, Kira Delmore & Kevin Fraser
Genetic variation is a fundamental component of biodiversity, and studying population structure, gene flow, and demographic history can help guide conservation strategies for many species. Like other aerial insectivores, the purple martin (Progne subis) is in decline, and yet their genetic background remains largely unknown. To address this knowledge gap, we assessed population structure in the nominate eastern subspecies (P. s. subis) with relation to natal dispersal and examined historical genetic patterns in all three...

Data from: Population genetics and independently replicated evolution of predator-associated burst speed ecophenotypy in mosquitofish

Thomas J DeWitt, Nicholas J Troendle, Mariana Mateos & Rodney Mauricio
Many species show replicated ecophenotypy due to recurring patterns of natural selection. Based on the presence or absence of pursuit predators, at least 17 species of fish repeatedly differentiated in body shape in a manner that increases burst swimming speed and the likelihood of predator escape. The predator-associated burst speed (PABS) ecophenotype is characterized by a small head and trunk and enlarged caudal region. Mechanisms promoting replicated phenotype-environment association include selection (without evolution), a single...

Phenotypic variation and genome-wide association studies of main culm panicle node number, maximum node production rate, and degree-days to heading in rice

Darlene Sanchez, Stanley Omar Samonte, Jasper Benedict Alpuerto, Peyton Croaker, Karina Morales, Yubin Yang, Lloyd Wilson, Rodante Tabien, Zongbu Yan, Michael Thomson & Endang Septiningsih
To understand the genetic basis of main culm panicle node number, maximum node production rate, and degree-days to heading in rice (Oryza sativa), we conducted genome-wide association studies using a diversity panel of 220 rice accessions and 854,832 SNP markers generated using genotyping-by-sequencing (GBS), with 1X coverage. The raw genotype data was filtered, selecting single nucleotide polymorphisms (SNPs) having less than 50% missing data and minimum allele frequency (MAF) >5%. After initial filtering, imputation was...

High quality, chromosome-scale genome assemblies: Comparisons of three Diaphorina citri (Asian Citrus Psyllid) geographic populations

Curtis Carlson, Anneliek Ter Horst, J. Spencer Johnston, Elizabeth Henry, Bryce Falk & Yen-Wen Kuo
The Asian citrus psyllid, Diaphorina citri, is the insect vector of the causal agent of huanglongbing (HLB), a devastating bacterial disease of commercial citrus. Few genomic resources exist for D. citri. In this study, we utilized PacBio HiFi and chromatin confirmation contact (Hi-C) sequencing to sequence, assemble, and compare three high quality, chromosome-scale genome assemblies of D. citri collected from California, Taiwan, and Uruguay. Our assemblies had final sizes of 282.67 Mb (California), 282.89 Mb...

Genotype by environment interactions for chronic wasting disease in farmed U.S. white-tailed deer

Christopher Seabury
Despite the implementation of enhanced management practices, chronic wasting disease (CWD) in U.S. white-tailed deer (Odocoileus virginianus; hereafter WTD) continues to expand geographically. Herein, we perform the largest genome-wide association analysis (GWAA) to date for CWD (n = 412 CWD-positive; n = 758 CWD-non-detect) using a custom Affymetrix Axiom® single nucleotide polymorphism (SNP) array (n = 121,010 SNPs), and confirm that differential susceptibility to CWD is a highly heritable (h2 = 0.611 ± 0.056) polygenic...

Literature review dataset on predation-risk effects

Scott Peacor, David Kimbro, Nathan Dorn, Justine Smith, Michael Sheriff & Michael Cherry
A well-accepted narrative in ecology is that prey modify traits to reduce predation risk, and the trait modification has costs large enough to cause ensuing demographic, trophic and ecosystem consequences, with implications for conservation, management, and agriculture. But ecology has a long history of emphasizing that quantifying the importance of an ecological process ultimately requires evidence linking a process to unmanipulated field patterns. We suspected that such process-linked-to pattern (PLP) studies were poorly represented in...

Data from: Physiological and transcriptional immune responses of a non-model arthropod to infection with different entomopathogenic groups

Joseph Black, Mason Clark & Gregory Sword
Insect immune responses to multiple pathogen groups including viruses, bacteria, fungi, and entomopathogenic nematodes have traditionally been documented in model insects such as Drosophila melanogaster, or medically important insects such as Aedes aegypti. Despite their potential importance in understanding the efficacy of pathogens as biological control agents, these responses are infrequently studied in agriculturally important pests. Additionally, studies often neglect to investigate responses against different pathogen groups, and typically focus on only a single time...

Litter decomposition rates across tropical montane and lowland forests are controlled foremost by climate

Rebecca Ostertag, Carla Restrepo, Iveren Abeim, Roxana Aragón, Michelle Ataroff, Hazel Chapman, Belen Fadrique, Grizelle González, Achim Häger, Jürgen Homeier, Luis Daniel Llambí, Rikke Reese Næsborg, Laura Nohemy Poma López, Jorge Andrés Ramirez Correa, Klara Scharnagl, Conrado Tobón, James W. Dalling, Patrick H. Martin, Iveren Abiem, Shin‐Ichiro Aiba, Esteban Alvarez‐Dávila, Augusta Y. Cueva‐Agila, Romina D. Fernández, Sybil G. Gotsch, Carlos Iñiguez‐Armijos … & Cameron B. Williams
The “hierarchy of factors” hypothesis states that decomposition rates are controlled primarily by climatic, followed by biological and soil variables. Tropical montane forests (TMF) are globally important ecosystems, yet there have been limited efforts to provide a biome-scale characterization of litter decomposition. We designed a common litter decomposition experiment replicated in 23 tropical montane sites across the Americas, Asia, and Africa and combined these results with a previous study of 23 sites in tropical lowland...

A global analysis of mosses reveals low phylogenetic endemism and highlights the importance of long-distance dispersal

Katie Sanbonmatsu & Daniel Spalink
Aim: Digitization of herbarium specimens and DNA sequencing efforts in the past decade have enabled integrative analyses of patterns of diversity and endemism in a phylogenetic context. Here, we compare the best available floristic databases to a comprehensive specimen database to examine spatial patterns of moss phylogenetic assembly. We test the hypotheses that 1) mosses exhibit phylogenetic regionalization, 2) islands contain significantly high phylogenetic diversity, and 3) that moss phylogenetic endemism is low on a...

Biogeographic consequences of shifting climate for the western massasauga (Sistrurus tergeminus)

Danielle Walkup, Michelle Lawing, Toby Hibbitts & Wade Ryberg
The western massasauga (Sistrurus tergeminus) is a small pit viper with an extensive geographic range, yet observations of this species are relatively rare. They persist in patchy and isolated populations, threatened by habitat destruction and fragmentation, mortality from vehicle collisions, and deliberate extermination. Changing climates may pose an additional stressor on the survival of isolated populations. Here, we evaluate historic, modern, and future geographic projections of suitable climate for S. tergeminus to outline shifts in...

Source code for dynamic models and simulations of mate sampling behavior

James Watts
Theory predicts that the strength of sexual selection (i.e., how well a trait predicts mating or fertilization success) should increase with population density, yet empirical support remains mixed. We explore how this discrepancy might reflect a disconnect between current theory and our understanding of the strategies individuals use to choose mates. We demonstrate that the density-dependence of sexual selection predicted by previous theory arises from the assumption that individuals automatically sample more potential mates at...

Data from: Patterns of genomic and allochronic strain divergence in the fall armyworm, Spodoptera frugiperda

Ashley Tessnow, Tyler Raszick, Patrick Porter & Gregory Sword
Speciation is the process through which reproductive isolation develops between distinct populations. Because this process takes time, speciation studies often necessarily examine populations within a species that are at various stages of divergence. The fall armyworm, Spodoptera frugiperda (J.E.Smith), is comprised of two strains (R=Rice & C=Corn) that serve as a novel system to explore population divergence in sympatry. Here, we use ddRADSeq data to show that fall armyworm strains in the field are largely...
