Adaptive associations among life history, reproductive traits, environment, and origin in the Wisconsin angiosperm flora

Ricardo Kriebel, Thomas Givnish, John Zaborsky, Jeffrey Rose, Daniel Spalink, Donald Waller, Kenneth Cameron & Kenneth Sytsma
PREMISE OF THE STUDY: We tested 25 classic and novel hypotheses regarding trait-origin, trait-trait, and trait-environment relationships to account for flora-wide variation in life history, habit, and especially reproductive traits using a plastid DNA phylogeny of most native (96.6%, or 1494/1547 species) and introduced (87.5%, or 690/789 species) angiosperms in Wisconsin, USA. METHODS: We assembled data on life history, habit, flowering, dispersal, mating system, and occurrence across open/closed/mixed habitats across species in the state phylogeny....

Comparison of environmental inference approaches for ecometric analyses: Using hypsodonty to estimate precipitation

Rachel A. Short, Katherine Pinson & A. Michelle Lawing
Ecometrics is the study of community-level functional trait-environment relationships. We use ecometric analyses to estimate paleoenvironment and to investigate community-level functional changes through time. We evaluate four methods that have been used or have the potential to be used in ecometric analyses for estimating paleoenvironment to determine whether there have been systematic differences in paleoenvironmental estimation due to choice of the estimation method. Specifically, we evaluated linear regression, polynomial regression, nearest neighbor, and maximum likelihood...

Data from: Co-occurrence of bobcats, coyotes, and ocelots in Texas

Jason Lombardi, Darryl MacKenzie, Michael Tewes, Humberto Perotto, Jose Mata & Tyler Campbell
Interspecific competition among carnivores has been linked to differences in behavior, morphology, and resource use. Insights into these interactions can enhance understanding of local ecological processes that can have impacts on the recovery of endangered species, such as the ocelot (Leopardus pardalis). Ocelots, bobcats (Lynx rufus), and coyotes (Canis latrans) share a small geographic range overlap from South Texas to south-central Mexico but relationships among the three are poorly understood. From May 2011 to March...

Lineage-specific patterns of chromosome evolution are the rule not the exception in Polyneoptera insects

Terrence Sylvester, Carl Hjelmen, Shawn Hanrahan, Paul Lenhart, Spencer Johnston & Heath Blackmon
The structure of a genome can be described at its simplest by the number of chromosomes and the sex chromosome system it contains. Despite over a century of study, the evolution of genome structure on this scale remains recalcitrant to broad generalisations that can be applied across clades. To address this issue, we have assembled a dataset of 823 karyotypes from the insect group Polyneoptera. This group contains orders with a range of variations in...

Data from: Decadal heat and drought drive body size of North American bison (Bison bison) along the Great Plains

Jeff Martin & Perry S. Barboza
Large grazers are visible and valuable indicators of the effects of projected changes in temperature and drought on grasslands. The grasslands of the Great Plains has supported the greatest number of bison (Bison bison; Linnaeus, 1758) since prehistoric times. We tested the hypothesis that body mass (BM; kg) and asymptotic body mass (ABM; kg) of Bison decline with rising temperature and increasing drought over both temporal and spatial scales along the Great Plains. Temporally, we...

Towards scaling laws for DDT in obstructed channels

Elaine S. Oran & Vadim N. Gamezo
In a coal mine, natural gas can leak through walls and accumulate in enclosed regions that are no longer being mined or ventilated. If there is an accidental spark in the region containing this gas, it can ignite a flame that may transition to detonation (DDT). An important problem is to assess if, when, and where DDT can occur, and thus provide information needed to design strong enough barriers to protect active mining areas. We...

Genome-wide association mapping to identify genetic loci for cold tolerance and cold recovery during germination in rice

Michael Thomson, Ranjita Thapa & Endang Septiningsih
To investigate the genetic architecture underlying cold tolerance during germination in rice (Oryza sativa), we conducted a genome-wide association study (GWAS) using a novel diversity panel of 257 rice accessions from around the world and 5,185 SNP markers from a 7K SNP marker array. Genotyping was performed using a 7K Illumina iSelect custom-designed array by following the Infinium HD Array Ultra Protocol. The 7K array, called the C7AIR, was designed by Dr. Susan McCouch’s Lab...

C. rufifacies heat stress data

Travis Rusch
The increased severity and frequency of elevated temperatures due to climate change is changing species distributions and driving thermal selection for several species, but many potential effects are still unknown. Here, we investigated the effects of an acute thermal stress on the oviposition performance of the hairy maggot blow fly Chrysomya rufifacies (Macquart), an introduced species of ecological, economic, and forensic importance. Adult virgins were exposed to 25°C, 42°C, or 44°C for 1-h, and then...

Data from: Widespread variation in stable isotope trophic position estimates: patterns, causes, and potential consequences

Mackenzie Kjeldgaard, Jeremy Hewlett & Micky Eubanks
Stable isotope analysis is one of the most widely used techniques to estimate trophic position and provides fundamental insight into the structure and management of ecological communities. To account for the effects of geographic variation in isotope levels, trophic position is typically estimated relative to an isotope “baseline” (i.e., material representing geographic variation) using a methodology such as a formula or statistical analysis. There is, however, remarkable variation in the baselines and methodologies used to...

Data from: Optimising sample sizes for animal distribution analysis using tracking data

Takahiro Shimada, Michele Thums, Mark Hamann, Colin Limpus, Graeme Hays, Nancy FitzSimmons, Natalie Wildermann, Carlos Duarte & Mark Meekan
1. Knowledge of the spatial distribution of populations is fundamental to management plans for any species. When tracking data are used to describe distributions, it is sometimes assumed that the reported locations of individuals delineate the spatial extent of areas used by the target population. 2. Here, we examine existing approaches to validate this assumption, highlight caveats, and propose a new method for a more informative assessment of the number of tracked animals (i.e. sample...

Data from: Disparate patterns of movements and visits to points of interest located in urban hotspots across U.S. metropolitan cities during COVID-19

Qingchun Li
We examined the effect of social distancing on changes in visits to urban hotspot points of interest. In a pandemic situation, urban hotspots could be potential superspreader areas as visits to urban hotspots can increase the risk of contact and transmission of a disease among a population. We mapped origin-destination networks from census block groups to points of interest (POIs), such as restaurants, museums, and schools, in sixteen cities in the United States. We adopted...

Raw in vitro screening data and R scripts for: A Bayesian method for population-wide cardiotoxicity hazard and risk characterization using an in vitro human model

Alexander Blanchette, Sarah Burnett, Fabian Grimm, Ivan Rusyn & Weihsueh Chiu
Human induced pluripotent stem cell (iPSC)-derived cardiomyocytes are an established model for testing potential chemical hazards. Inter-individual variability in toxicodynamic sensitivity has also been demonstrated in vitro; however, quantitative characterization of the population-wide variability has not been fully explored. We sought to develop a method to address this gap by combining a population-based iPSC-derived cardiomyocyte model with Bayesian concentration-response modeling. A total of 136 compounds, including 44 pharmaceuticals and 82 environmental chemicals, were tested in...

Sun compass neurons are tuned to migratory orientation in monarch butterflies

Tu Anh Thi Nguyen, M. Jerome Beetz, Christine Merlin & Basil El Jundi
Every autumn, monarch butterflies migrate from North America to their overwintering sites in Central Mexico. To maintain their southward direction, these butterflies rely on celestial cues as orientation references. The position of the sun combined with additional skylight cues are integrated in the central complex, a region in the butterfly’s brain that acts as an internal compass. However, the central complex does not solely guide the butterflies on their migration but helps monarchs in their...

Identification and characterization of QTLs for fruit quality traits in peach through a multi-family approach

Zena Rawandoozi, Timothy P. Hartmann, Silvia Carpenedo, Ksenija Gasic, Cassia Da Silva Linge, Lichun Cai, Eric Van De Weg & David H. Byrne
Background Fruit quality traits have a significant effect on consumer acceptance and subsequently on peach (Prunus persica (L.) Batsch) consumption. Determining the genetic bases of key fruit quality traits is essential for the industry to improve fruit quality and increase consumption. Pedigree-based analysis across multiple peach pedigrees can identify the genomic basis of complex traits for direct implementation in marker-assisted selection. This strategy provides breeders with better-informed decisions and improves selection efficiency and, subsequently, saves...

Herbivory Improves the Fitness of Predatory Beetles

Todd Ugine, Avneet Nagra, Robert Grebenok, Spencer Behmer & John Losey
While many predatory arthropods consume non-prey foods from lower trophic levels, little is known about what drives the shift from predator to omnivore. Predatory lady beetles often consume non-prey foods like plant foliage and pollen. One species, Coccinella septempunctata, eats foliage to redress sterol deficits caused by eating sterol-deficient prey. Here we explore how omnivory benefits lady beetle fitness. We reared seven species of lady beetles – from five genera distributed across the tribe Coccinellini...

Data from: Savannas after afforestation: assessment of herbaceous community responses to wildfire versus native tree planting

Thaís M. Haddad, Ricardo A. G. Viani, Mário G. B. Cava, Giselda Durigan & Joseph V. Veldman
Afforestation and fire exclusion are pervasive threats to tropical savannas. In Brazil, laws limiting prescribed burning hinder the study of fire in the restoration of Cerrado plant communities. We took advantage of a 2017 wildfire to evaluate the potential for tree cutting and fire to promote the passive restoration of savanna herbaceous plant communities after destruction by exotic tree plantations. We sampled a burned pine plantation (Burned Plantation); a former plantation that was harvested and...

Data from: Thoracic underreplication in Drosophila species estimates a minimum genome size and the dynamics of added DNA

Carl E. Hjelmen, V. Renee Holmes, Crystal G. Burrus, Elizabeth Piron, Melissa Mynes, Margaret A. Garrett, Heath Blackmon & J. Spencer Johnston
Many cells in the thorax of Drosophila were found to stall during replication, a phenomenon known as underreplication. Unlike underreplication in nuclei of salivary and follicle cells, this stall occurs with less than one complete round of replication. This stall point allows precise estimations of early-replicating euchromatin and late-replicating heterochromatin regions, providing a powerful tool to investigate the dynamics of structural change across the genome. We measure underreplication in 132 species across the Drosophila genus...

An updated life history scheme for marine fishes predicts recruitment variability and sensitivity to exploitation

Colleen Petrik, Fernando González Taboada, Charles Stock & Jorge Sarmiento
Aim: Patterns of population renewal in marine fishes are often irregular and lead to volatile fluctuations in abundance that challenge management and conservation efforts. Here, we examine the relationship between life history strategies and recruitment variability in exploited marine fish species using a macroecological approach. Location: Global ocean. Time period: 1950-2018. Major taxa studied: Bony and cartilaginous fish. Methods: Based on trait data for 244 marine fish species, we objectively extend the established Equilibrium-Periodic-Opportunistic (E-P-O)...

Major inconsistencies of inferred population genetic structure estimated in a large set of domestic horse breeds using microsatellites

Stephan Funk, Jose Luis Vega-Pla, Cristina Luis, Gus Cothran & Rytis Juras
STRUCTURE remains the most applied tool aimed at recovering the true, but unknown, population structure from observed microsatellite data or other genetic markers. About 30% of STRUCTURE-based studies could not be reproduced (Gilbert et al., 2012). Here we use a large set of data from 2323 horses from 93 domestic breeds plus the Przewalski horse, typed at 15 microsatellite markers, to evaluate how program settings, in particular the so far insufficiently evaluated number of replicates,...

Divergent neurogenomic responses shape social learning of both personality and mate preference

Pablo Delclos, Santiago Forero & Gil Rosenthal
Behavior plays a fundamental role in shaping the origin and fate of species. Mating decisions can act to promote or restrict gene flow, as can personality traits that influence dispersal and niche use. Mate choice and personality are often both learned and therefore influenced by an individual’s social environment throughout development. Likewise, the molecular pathways that shape these behaviors may also be co-expressed. In this study on swordtail fish (Xiphophorus birchmanni), we show that female...

Emergent social cohesion for coping with community disruptions in disasters

Chao Fan, Yucheng Jiang & Ali Mostafavi
Social cohesion is an important determinant of community well-being, especially in times of distress such as disasters. This study investigates the phenomena of emergent social cohesion, which is characterized by abrupt, temporary, and extensive social ties with the goal of sharing and receiving information regarding a particular event influencing a community. In the context of disasters, emergent social cohesion, enabled by social media usage, could play a significant role in improving the ability of communities...
