Data from: Ontogenetic variation in epibiont community structure in the deep-sea yeti crab, Kiwa puravida: convergence among crustaceans

Shana K. Goffredi, Ann Gregory, William Joe Jones, Norma M. Morella & Reid I. Sakamoto
Recent investigations have demonstrated that unusually ‘hairy’ yeti crabs within the family Kiwaidae associate with two predominant filamentous bacterial families, the Epsilon and Gammaproteobacteria. These analyses, however, were based on samples collected from a single body region, the setae of pereopods. To more thoroughly investigate the microbiome associated with Kiwa puravida, a yeti crab species from Costa Rica, we utilized barcoded 16S rRNA amplicon pyrosequencing, as well as microscopy and terminal restriction fragment length polymorphism...

Data from: Strong selection genome-wide enhances fitness trade-offs across environments and episodes of selection

Jill Theresa Anderson, Cheng-Ruei Lee & Thomas Mitchell-Olds
Fitness trade-offs across episodes of selection and environments influence life-history evolution and adaptive population divergence. Documenting these trade-offs remains challenging as selection can vary in magnitude and direction through time and space. Here, we evaluate fitness trade-offs at the levels of the whole organism and the quantitative trait locus (QTL) in a multiyear field study of Boechera stricta (Brassicaceae), a genetically tractable mustard native to the Rocky Mountains. Reciprocal local adaptation was pronounced for viability,...

Data from: Chronic exposure to low-dose radiation at Chernobyl favours adaptation to oxidative stress in birds

Ismael Galván, Andrea Bonisoli-Alquati, Shanna Jenkinson, Ghanem Ghanem, Kazumasa Wakamatsu, Timothy A. Mousseau & Anders P. Møller
1. Ionizing radiation produces oxidative stress, but organisms can adapt to their exposure with physiological adaptive responses. However, the role of radioadaptive responses in wild populations remains poorly known. 2. At Chernobyl, studies of birds and other taxa including humans show that chronic exposure to radiation depletes antioxidants and increases oxidative damage. Here we present analyses of levels of the most important intracellular antioxidant (i.e., glutathione, GSH), its redox status, DNA damage and body condition...

Data from: Effects of increased flight on the energetics and life history of the butterfly Speyeria mormonia

Kristjan Niitepõld & Carol L. Boggs
Movement uses resources that may otherwise be allocated to somatic maintenance or reproduction. How does increased energy expenditure affect resource allocation? Using the butterfly Speyeria mormonia, we tested whether experimentally increased flight affects fecundity, lifespan or flight capacity. We measured body mass (storage), resting metabolic rate and lifespan (repair and maintenance), flight metabolic rate (flight capacity), egg number and composition (reproduction), and food intake across the adult lifespan. The flight treatment did not affect body...

Geolocators lead to better measures of timing and renesting in Black-tailed Godwits and reveal the bias of traditional observational methods

Mo Verhoeven, Jelle Loonstra, Alice McBride, Pablo Macias, Wiebe Kaspersma, Jos Hooijmeijer, Egbert Van Der Velde, Christiaan Both, Nathan Senner & Theunis Piersma
Long‐term population studies can identify changes in population dynamics over time. However, to realize meaningful conclusions, these studies rely on accurate measurements of individual traits and population characteristics. Here, we evaluate the accuracy of the observational methods used to measure reproductive traits in individually marked black‐tailed godwits (Limosa limosa limosa). By comparing estimates from traditional methods with data obtained from light‐level geolocators, we provide an accurate estimate of the likelihood of renesting in godwits and...

Sandy seeds: Armor or invisibility cloak? Mucilage-bound sand physically protects seeds from rodents and invertebrates

Eric LoPresti, Vincent Pan, Cecilia Girvin, Gabhriel Barber, Sierra Jaeger & John Orrock
Seeds represent a stage of a plant’s life cycle that is extremely vulnerable to predation, which, unlike most vegetative herbivory, is fatal to the individual. As such, understanding the distribution and abundance of plants may rely upon understanding seed defenses: characteristics of seeds that make them more difficult for granivores to locate, make them less beneficial for granivores to consume, or both. Seeds that produce mucilage are widespread and found across many families and species....

Data from: Dissecting genome-wide association signals for loss-of-function phenotypes in sorghum flavonoid pigmentation traits

Geoffrey P. Morris, Davina H. Rhodes, Zachary Brenton, Punna Ramu, Vinayan Madhumal Thayil, Santosh Deshpande, C. Thomas Hash, Charlotte Acharya, Sharon E. Mitchell, Edward S. Buckler, Jianming Yu & Stephen Kresovich
Genome-wide association studies (GWAS) are a powerful method to dissect the genetic basis of traits, though in practice the effects of complex genetic architecture and population structure remain poorly understood. To compare mapping strategies we dissect the genetic control of flavonoid pigmentation traits in the cereal grass sorghum using high-resolution genotyping-by-sequencing (GBS) SNP markers. Studying the grain tannin trait, we find that General Linear Models (GLM) are not able to precisely map tan1-a, a known...

Data from: Probing the ecology and climate of the Eocene Southern Ocean with sand tiger sharks Striatolamia macrota

Sora Kim, Sarah Zeichner, Albert Colman, Howie Scher, Jürgen Kriwet & Thomas Mörs
During the Eocene, the Earth climate system transitioned from greenhouse to icehouse conditions. Central to many explanations is the Southern Ocean—where tectonic configurations influenced oceanic gateways, ocean circulation reduced heat transport, and/or greenhouse gas declines prompted glaciation. To date, few studies have explored the implications of this climate transition on high latitude, marine vertebrates. Seymour Island near the Antarctic Peninsula preserves a rich, diverse fossil assemblage in the Tertiary Eocene La Meseta (TELM) Formation (Fm)....

Climate change and lithium mining influence flamingo abundance in the Lithium Triangle

Jorge Gutiérrez, Johnnie Moore, Patrick Donnelli, Cristina Dorador, Juan Navedo & Nathan Senner
The development of technologies to slow climate change has been identified as a global imperative. Nonetheless, such ‘green’ technologies can potentially have negative impacts on biodiversity. We explored how climate change and the mining of lithium for green technologies influence surface water availability, primary productivity, and the abundance of three threatened and economically important flamingo species in the ‘Lithium Triangle’ of the Chilean Andes. We combined climate and primary productivity data with remotely sensed measures...

Novel host plant unmasks heritable variation in plant preference within an insect population

Rachel A Steward, Rebecca S Epanchin-Niell & Carol L Boggs
Introductions of novel plant species can disturb the historical resource environment of herbivorous insects, resulting in strong selection to either adopt or exclude the novel host. However, an adaptive response depends on heritable genetic variation for preference or performance within the targeted herbivore population, and it is unclear how heritability of host-use preference may differ between novel and historical hosts. Pieris macdunnoughii butterflies in the Rocky Mountains lay eggs on the nonnative mustard Thlaspi arvense,...
