An optimized, high-throughput and cost-effective genotyping method applicable to various crop breeding populations is very important in this genomic era. We have developed an optimized Nextera skim-sequencing (skim-seq) approach to genotype different populations that can be used for genetics studies and genomics-assisted breeding. We performed skim-seq on a variety of populations developed through doubled haploid (DH) technology, inter-specific recombinants developed through introgression, amphidiploid developed through wide crosses, and on known monosomic samples. 1. A doubled...

Northern Bobwhite juvenile survival southwest Missouri 2016-2018

Emily Sinnott, Frank Thompson, Mitch Weegman & Thomas Thompson
These data and code are associated with the publication in Ornithological Applications entitled "Northern Bobwhite juvenile survival is greater on native grasslands managed with fire and grazing, and lower in non-native field borders and strip crop fields." We evaluated the influence of brood age, vegetation cover type, woody vegetation structure, habitat management, and landscape cover on juvenile survival in southwest Missouri 2016-2018.

Experimental variation in the spatial deposition of trace metals in feathers revealed using synchrotron x-ray fluorescence

Fardausi Akhter, Graham Fairhurst, Peter Blanchard, Karen Machin, Rob Blyth, Julie Thompson, Jamille McLeod, Renfei Feng & Catherine Soos
Feathers can be used to investigate exposure to pollution in birds because they are a secondary route for the excretion of trace elements. Evidence based on analytical imaging and spectroscopy suggests that the spatial distribution of the essential trace element zinc within feathers is related to melanin pigmentation. However, our understanding of how trace elements are deposited into growing feathers is poor and has been hampered by a lack of analytical tools to examine the...

A haplotype-led approach to increase the precision of wheat breeding

Cristobal Uauy, Jemima Brinton, Ricardo Ramirez-Gonzalez, James Simmonds, Luzie Wingen, Simon Orford, Simon Griffiths, Georg Haberer, Manuel Spannagl, Sean Walkowiak & Curtis Pozniak
Crop productivity must increase at unprecedented rates to meet the needs of the growing worldwide population. Exploiting natural variation for the genetic improvement of crops plays a central role in increasing productivity. Although current genomic technologies can be used for high-throughput identification of genetic variation, methods for efficiently exploiting this genetic potential in a targeted, systematic manner are lacking. Here, we developed a haplotype-based approach to identify genetic diversity for crop improvement using genome assemblies...

A new Late Devonian flora from Sonid Zuoqi, Inner Mongolia, northeastern China

Lingqi Bai, Pu Huang, Ning Yang, Wenxin Ju, Jianbo Liu, James Basinger, Honghe Xu & Jinzhuang Xue
The Silurian and Devonian plant fossil record is the basis for our understanding of the early evolution of land plants, yet our appreciation of early global phytogeographic evolution has been constrained by the focus of most studies on deposits from Europe, North America, and more recently South China. Devonian plants have been rarely recorded from northeastern China, and among previous records, few plants have been illustrated and formally described. In this article, megafossil plants representing...

Divorce in Northern Flickers

Karen Wiebe
Divorce is widespread among species of birds and may either be an adaptive strategy to secure a better mate or territory or be a non-adaptive result of a failure to maintain the pairbond. I examined the causes and consequences for divorce in the Norther Flicker (Colaptes auratus), a migratory woodpecker with a high annual mortality rate. In a long-term population study of 1793 breeding pairs over 17 years, the within-season divorce rate was 4.6% and...

Terrestrial lichen data for Saskatchewan, Canada

Jill Johnstone, Ruth Greuel, Sarah Hart, Alexandre Truchon-Savard & Philip McLoughlin
Increased fire activity due to climate change may impact the successional dynamics of boreal forests, with important consequences for caribou habitat. Early successional forests have been shown to support lower quantities of caribou forage lichens, but geographic variation in, and controls on, the rates of lichen recovery have been largely unexplored. In this study, we sampled across a broad region in northwestern Canada to compare lichen biomass accumulation in ecoprovinces, including the Saskatchewan Boreal Shield,...

Genomic distinctness despite shared color patterns among threatened populations of a tiger beetle

Rowan French, Aaron Bell, Kiara Calladine, John Acorn & Felix Sperling
Conservation biologists have long debated the value of subspecies, which are morphologically and geographically identifiable but not necessarily evolutionarily distinctive. One example of a controversial subspecies is Cicindela formosa gibsoni, a tiger beetle that is nationally listed as threatened in Canada and whose taxonomic status is based primarily on its unique elytral (forewing) color pattern. To determine whether C. f. gibsoni represents one or more genetically distinctive units, we sampled 14 populations within or near...

Birds may decorated their nest to exploit a fear of feathers

Tore Slagsvold & Karen L. Wiebe
This dataset contains data from experiments carried out in a woodland area and described in the paper: “T. Slagsvold, and Wiebe, K. L. (2021) "Nest decoration: birds exploit a fear of feathers to guard their nest from usurpation". The experiments investigated a new hypothesis, namely that some cavity nesting birds, like titmice, add feathers on the top of their nest to prevent usurpation by triggering a fear response in their rivals. We presented pied flycatchers...

Woodpeckers and other excavators maintain the diversity of cavity-nesting vertebrates

M. Kurtis Trzcinski, Kristina Cockle, Andrea Norris, Max Edworthy, Karen Wiebe & Kathy Martin
Woodpeckers and other excavators create most of the holes used by secondary tree-cavity nesting vertebrates (SCNs) in North American temperate mixedwood forests, but the degree to which excavators release SCNs from nest-site limitation is debated. Our goal was to quantify how excavators maintain the diversity and abundance of secondary cavity nesters in a temperate forest through the creation of tree cavities. We examined the short- and long-term (legacy) effects of excavators (principally woodpeckers, but also...

Insect-mediated apparent competition between mammals in a boreal food web

Guillemette Labadie, Philip D. McLoughlin, Mark Hebblewhite & Daniel Fortin
Datasets generated and analyzed within the study area located in the Côte-Nord region of Québec, Canada. "DataFinal_Vegetation.csv" was used to evaluate the availability of deciduous vegetation (column Cover_Deciduous) in stands impacted by the spruce budworm (SBW, severity index values presented in column SBW_SevCum) outbreak and test our prediction that the reduction in canopy cover caused by SBW in coniferous stands would result in greater deciduous vegetation. We determined the percentage cover of deciduous vegetation for...

Data from: Resource exploitation collapses the home range of an apex predator

Melanie Dickie, Robert Serrouya, Avgar Tal, Philllip McLouglin, Scott McNay, Craig DeMars & Stan Boutin
Optimizing energy acquisition and expenditure is a fundamental trade-off for consumers, strikingly reflected in how mobile organisms use space. Several studies have established that home range size decreases as resource density increases, but the balance of costs and benefits associated with exploiting a given resource density is unclear. We evaluate how the ability of consumers to exploit their resources through movement (termed “resource exploitation”) interacts with resource density to influence home range size. We then...

Social effects on annual fitness in red squirrels

Andrew McAdam, Quinn Webber, Ben Dantzer, Jeff Lane & Stan Boutin
When resources are limited, mean fitness is constrained and competition can cause genes and phenotypes to enhance an individual’s own fitness while reducing the fitness of their competitors. Negative social effects on fitness have the potential to constrain adaptation, but the interplay between ecological opportunity and social constraints on adaptation remains poorly studied in nature. Here, we tested for evidence of phenotypic social effects on annual fitness (survival and reproductive success) in a long-term study...

Coral degradation impairs learning of non-predators by Whitetail damselfish

Douglas Chivers, Mark McCormick, Eric Fakan, Jake Edmiston & Maud Ferrari
A prerequisite for effective antipredator responses is the ability of the prey to distinguish animals that pose a threat from those that do not. Prey often have efficient learning mechanisms to learn threats but learning to recognize nonpredators may be equally or more important. Moreover, the ability to generalize learned information is of key importance for prey animals. Prey take information they know about one species to make ‘educated guesses’ about the predatory/nonpredatory status of...

Egg covering in great tits and effects on pied flycatchers

Tore Slagsvold & Karen L. Wiebe
This dataset contains data from experiments carried out in a woodland area and described in the paper: “T. Slagsvold, and Wiebe, K. L. (2021) “Egg covering in cavity nesting birds may prevent nest usurpation by other species.” https://doi.org/10.1007/s00265-021-03045-w The experiments investigated a new hypothesis, namely that the cavity nesting birds, like titmice, cover their eggs when they leave the nest during the egg laying period to prevent usurpation of the cavity by other birds. We...
