Data from: Chronic protein restriction in mice impacts placental function and maternal body weight before fetal growth

Paula N. Gonzalez, Malgorzata Gasperowicz, Jimena Barbeito-Andrés, Natasha Klenin, James C. Cross & Benedikt Hallgrímsson
Mechanisms of resource allocation are essential for maternal and fetal survival, particularly when the availability of nutrients is limited. We investigated the responses of feto-placental development to maternal chronic protein malnutrition to test the hypothesis that maternal low protein diet produces differential growth restriction of placental and fetal tissues, and adaptive changes in the placenta that may mitigate impacts on fetal growth. C57BL/6J female mice were fed either a low-protein diet (6% protein) or control...

Data from: Female and male life tables for seven wild primate species

Anne M. Bronikowski, Marina Cords, Susan C. Alberts, Jeanne Altmann, Diane K. Brockman, Linda M. Fedigan, Anne Pusey, Tara Stoinski, Karen B. Strier & William F. Morris
We provide male and female census count data, age-specific survivorship, and female age-specific fertility estimates for populations of seven wild primates that have been continuously monitored for at least 29 years: sifaka (Propithecus verreauxi) in Madagascar; muriqui (Brachyteles hypoxanthus) in Brazil; capuchin (Cebus capucinus) in Costa Rica; baboon (Papio cynocephalus) and blue monkey (Cercopithecus mitis) in Kenya; chimpanzee (Pan troglodytes) in Tanzania; and gorilla (Gorilla beringei) in Rwanda. Using one-year age-class intervals, we computed point...

Data from: Closely coupled evolutionary history of ecto- and endosymbionts from two distantly related animal phyla

Judith Zimmermann, Cecilia Wentrup, Miriam Sadowski, Anna Blazejak, Harald R. Gruber-Vodicka, Manuel Kleiner, Joerg A. Ott, Bodil Cronholm, Pierre De Wit, Christer Erséus & Nicole Dubilier
The level of integration between associated partners can range from ectosymbioses to extracellular and intracellular endosymbioses, and this range has been assumed to reflect a continuum from less intimate to evolutionarily highly stable associations. In this study, we examined the specificity and evolutionary history of marine symbioses in a group of closely related sulphur-oxidizing bacteria, called Candidatus Thiosymbion, that have established ecto- and endosymbioses with two distantly related animal phyla, Nematoda and Annelida. Intriguingly, in...

Data from: Are migratory behaviours of bats socially transmitted?

Erin F. Baerwald & Robert M. R. Barclay
To migrate, animals rely on endogenous, genetically inherited programmes, or socially transmitted information about routes and behaviours, or a combination of the two. In long-lived animals with extended parental care, as in bats, migration tends to be socially transmitted rather than endogenous. For a young bat to learn migration via social transmission, they would need to follow an experienced individual, most likely one roosting nearby. Therefore, we predicted that bats travelling together originate from the...

Data from: Variation in ligand responses of the bitter taste receptors TAS2R1 and TAS2R4 among New World monkeys

Background: New World monkeys (NWMs) are unique in that they exhibit remarkable interspecific variation in color vision and feeding behavior, making them an excellent model for studying sensory ecology. However, it is largely unknown whether non-visual senses co-vary with feeding ecology, especially gustation, which is expected to be indispensable in food selection. Bitter taste, which is mediated by bitter taste receptors (TAS2Rs) in the tongue, helps organisms avoid ingesting potentially toxic substances in food. In...

Data from: Phylogenomic reconstruction of sportive lemurs (genus Lepilemur) recovered from mitogenomes with inferences for Madagascar biogeography

Runhua Lei, Cynthia L. Frasier, Melissa T.R. Hawkins, Shannon E. Engberg, Carolyn A. Bailey, Steig E. Johnson, Adam T. McLain, Colin P. Groves, George H. Perry, Stephen D. Nash, Russell A. Mittermeier &
The family Lepilemuridae includes 26 species of sportive lemurs, most of which were recently described. The cryptic morphological differences confounded taxonomy until recent molecular studies; however, some species’ boundaries remain uncertain. To better understand the genus Lepilemur, we analyzed 35 complete mitochondrial genomes representing all recognized 26 sportive lemur taxa and estimated divergence dates. With our dataset we recovered 25 reciprocally monophyletic lineages, as well as an admixed clade containing Lepilemur mittermeieri and Lepilemur dorsalis....

Data from: Discovery of metabolic biomarkers for Duchenne Muscular Dystrophy within a natural history study

Simina M. Boca, Maki Nishida, Michael Harris, Shruti Rao, Amrita K. Cheema, Kirandeep Gill, Haeri Seol, Lauren P. Morgenroth, Erik Henricson, Craig McDonald, Jean K. Mah, Paula R. Clemens, Eric P. Hoffman, Yetrib Hathout & Subha Madhavan
Serum metabolite profiling in Duchenne muscular dystrophy (DMD) may enable discovery of valuable molecular markers for disease progression and treatment response. Serum samples from 51 DMD patients from a natural history study and 22 age-matched healthy volunteers were profiled using liquid chromatography coupled to mass spectrometry (LC-MS) for discovery of novel circulating serum metabolites associated with DMD. Fourteen metabolites were found significantly altered (1% false discovery rate) in their levels between DMD patients and healthy...

Data from: Alloparenting is associated with reduced maternal lactation effort and faster weaning in wild chimpanzees

Iulia Badescu, David P. Watts, M. Anne Katzenberg & Daniel W. Sellen
Alloparenting, when individuals other than the mother assist with infant care, can vary between and within populations and has potential fitness costs and benefits for individuals involved. We investigated the effects of alloparenting on the speed with which infants were weaned, a potential component of maternal fitness because of how it can affect inter-birth intervals, in wild chimpanzees (Pan troglodytes schweinfurthii) at Ngogo, Uganda. We also provide, to our knowledge, the first description of alloparenting...

Data from: Inbreeding avoidance and female mate choice shape reproductive skew in capuchin monkeys (Cebus capucinus imitator)

Eva C. Wikberg, Katherine M. Jack, Linda M. Fedigan, Fernando A. Campos, Akiko S. Yahsima, Mackenzie L. Bergstrom, Tomohide Hiwatashi, Shoji Kawamura, Katharine M. Jack & Akiko S. Yashima
Reproductive skew in multimale groups may be determined by the need for alpha males to offer reproductive opportunities as staying incentives to subordinate males (concessions), by the relative fighting ability of the alpha male (tug-of-war) or by how easily females can be monopolized (priority-of-access). These models have rarely been investigated in species with exceptionally long male tenures, such as white-faced capuchins, where female mate choice for novel unrelated males may be important in shaping reproductive...

Data from: Genomic analysis reveals hidden biodiversity within colugos, the sister group to primates

Victor C. Mason, Gang Li, Patrick Minx, Jurgen Schmitz, Gennady Churakov, Liliya Doronina, Amanda D. Melin, Nathaniel J. Dominy, Norman T-L. Lim, Mark S. Springer, Richard K. Wilson, Wesley C. Warren, Kristofer M. Helgen & William J. Murphy
Colugos are one of the most poorly studied mammals despite their centrality to resolving supraordinal primate relationships. Two described species of these gliding mammals are the sole living members of the order Dermoptera, distributed throughout Southeast Asia. We generated a draft genome sequence for a Sunda colugo and a Philippine colugo reference alignment, and used these to identify colugo-specific genetic changes that were enriched in sensory and musculo-skeletal related genes that likely underlie their nocturnal...

Data from: Adaptive genomic divergence under high gene flow between freshwater and brackish-water ecotypes of prickly sculpin (Cottus asper) revealed by Pool-Seq

Stefan Dennenmoser, Steven M. Vamosi, Arne W. Nolte & Sean M. Rogers
Understanding the genomic basis of adaptive divergence in the presence of gene flow remains a major challenge in evolutionary biology. In prickly sculpin (Cottus asper), an abundant euryhaline fish in northwestern North America, high genetic connectivity among brackish-water (estuarine) and freshwater (tributary) habitats of coastal rivers does not preclude the build-up of neutral genetic differentiation and emergence of different life history strategies. Because these two habitats present different osmotic niches, we predicted high genetic differentiation...

Data from: Maternal stress-associated cortisol stimulation may protect embryos from cortisol excess in zebrafish

Erin Faught, Carol Best & Mathilakath M. Vijayan
Abnormal embryo cortisol level causes developmental defects and poor survival in zebrafish (Danio rerio). However, no study has demonstrated that maternal stress leads to higher embryo cortisol content in zebrafish. We tested the hypothesis that maternal stress-associated elevation in cortisol levels increases embryo cortisol content in this asynchronous breeder. Zebrafish mothers were fed cortisol-spiked food for 5 days, to mimic maternal stress, followed by daily breeding for 10 days to monitor temporal embryo cortisol content....

Data from: Convergent local adaptation to climate in distantly related conifers

Sam Yeaman, Kathryn A. Hodgins, Katie E. Lotterhos, Haktan Suren, Simon Nadeau, Kristin A. Nurkowski, Pia Smets, Tongli Wang, Laura K. Gray, Katharina J. Liepe, Andreas Hamann, Jason A. Holliday, Michael C. Whitlock, Loren H. Rieseberg & Sally N. Aitken
When confronted with an adaptive challenge, such as extreme temperature, closely related species frequently evolve similar phenotypes using the same genes. Although such repeated evolution is thought to be less likely in highly polygenic traits and distantly related species, this has not been tested at the genome scale. We performed a population genomic study of convergent local adaptation among two distantly related species, lodgepole pine and interior spruce. We identified a suite of 47 genes,...

Data from: Genetic structure of phenotypic robustness in the Collaborative Cross mouse diallel panel

Paula N. Gonzalez, Mihaela Pavlicev, Philipp Mitteroecker, Fernando Pardo-Manuel De Villena, Richard Spritz, Ralph Marcucio & Benedikt Hallgrimsson
Developmental stability and canalization describe the ability of developmental systems to minimize phenotypic variation in the face of stochastic micro-environmental effects, genetic variation and environmental influences. Canalization is the ability to minimize the effects of genetic or environmental effects, while developmental stability is the ability to minimize the effects of micro-environmental effects within individuals. Despite much attention, the mechanisms that underlie these two components of phenotypic robustness remain unknown. We investigated the genetic structure of...

Data from: Non-equilibrium dynamics and floral trait interactions shape extant angiosperm diversity

Brian C. O'Meara, Stacey D. Smith, W. Scott Armbruster, Lawrence D. Harder, Christopher R. Hardy, Lena C. Hileman, Larry Hufford, Amy Litt, Susana Magallon, Stephen A. Smith, Peter F. Stevens, Charles B. Fenster & Pamela K. Diggle
Why are some traits and trait combinations exceptionally common across the tree of life, whereas others are vanishingly rare? The distribution of trait diversity across a clade at any time depends on the ancestral state of the clade, the rate at which new phenotypes evolve, the differences in speciation and extinction rates across lineages, and whether an equilibrium has been reached. Here we examine the role of transition rates, differential diversification (speciation minus extinction), and...
