Data from: The coevolution of lifespan and reversible plasticity

Irja Ida Ratikainen & Hanna Kokko
Reversible phenotypic plasticity, the ability to change one’s phenotype repeatedly throughout life, can be selected for in environments that do not stay constant throughout an individual’s lifetime. It might also mitigate senescence, as the mismatch between the varying environment and a non-plastic individual’s traits is likely to increase as time passes. To understand why reversible plasticity may covary with lifespan, studies tend to assume unidirectional causality: plasticity evolves under suitable rates of environmental variation with...

Data from: Cost of dispersal in a social mammal: body mass loss and increased stress

Nino Maag, Gabriele Cozzi, Andrew Bateman, Michael Heistermann, Andre Ganswindt, Marta Manser, Tim Clutton-Brock & Arpat Ozgul
Dispersal is a key process influencing the dynamics of socially and spatially structured populations. Dispersal success is determined by the state of individuals at emigration and the costs incurred after emigration. However, quantification of such costs is often difficult, due to logistical constraints of following wide-ranging individuals. We investigated the effects of dispersal on individual body mass and stress hormone levels in a cooperative breeder, the meerkat (Suricata suricatta). We measured body mass and faecal...

A sample of Saturn interior density profiles derived with MCMC and gravity-based likelihood.

Naor Movshovitz, Jonathan Fortney, Chris Mankovich, Daniel Thorngren & Ravit Helled
We ran a Markov-Chain Monte Carlo algorithm to derive the posterior distribution of density profiles for Saturn, where the likelihood function was a chi-squared distributed distance of each curve's gravity coefficients from the values reported for that planet by the Cassini radio science team (Iess et al., 2019). The result is a large sample of interior profiles of Saturn consistent with observation and minimally constrained by model assumptions. This sample is archived here in sufficiently...

Data from: Is MHC diversity a better marker for conservation than neutral genetic diversity? a case study of two contrasting dolphin populations

Oliver Manlik, Michael Krutzen, Anna M. Kopps, Janet Mann, Lars Bejder, Simon J. Allen, Celine Frere, Richard C. Connor & William B. Sherwin
Genetic diversity is essential for populations to adapt to changing environments. Measures of genetic diversity are often based on selectively neutral markers, such as microsatellites. Genetic diversity to guide conservation management, however, is better reflected by adaptive markers, including genes of the major histocompatibility complex (MHC). Our aim was to assess MHC and neutral genetic diversity in two contrasting bottlenose dolphin (Tursiops aduncus) populations in Western Australia—one apparently viable population with high reproductive output (Shark...

Data from: Warming reduces the effects of enrichment on stability and functioning across levels of organization in an aquatic microbial ecosystem

Andrea Tabi, Owen Petchey & Frank Pennekamp
Warming and nutrient enrichment are major environmental factors shaping ecological dynamics. However, cross-scale investigation of their combined effects by linking theory and experiments is lacking. We collected data from aquatic microbial ecosystems investigating the interactive effects of warming (constant and rising temperatures) and enrichment across levels of organization and contrasted them with community models based on metabolic theory. We found high agreement between our observations and theoretical predictions: we observed in many cases the predicted...

Data from: Dispersal syndromes can impact ecosystem functioning in spatially structured freshwater populations

Chelsea J. Little, Emanuel A. Fronhofer & Florian Altermatt
Dispersal can strongly influence ecological and evolutionary dynamics. Besides the direct contribution of dispersal to population dynamics, dispersers often differ in their phenotypic attributes from non-dispersers, which leads to dispersal syndromes. The consequences of such dispersal syndromes have been widely explored at the population and community level, however, to date, ecosystem-level effects remain unclear. Here, we examine whether dispersing and resident individuals of two different aquatic keystone invertebrate species have different contributions to detrital processing,...

Long-term movements and home range changes: rapid territory shifts in meerkats

Bart Kranstauber, Tim Clutton-Brock & Marta Manser
1. Territoriality and stable home ranges are a common space use pattern among animals. These ranges provide its inhabitants with important resources and thus favourable territories are associated with an increased fitness. While the role of territory quality and changes of territory ownership have often been investigated, the changes of territorial boundaries have been less studied. 2. Here we investigated space use changes in a social mammal species, applying a novel analytical approach, calculating long-term...

Distinct genomic signals of lifespan and life history evolution in response to postponed reproduction and larval diet in Drosophila

Katja Hoedjes, Joost Van Den Heuvel, Martin Kapun, Laurent Keller, Thomas Flatt & Bas Zwaan
Reproduction and diet are two major factors controlling the physiology of aging and life history, but how they interact to affect the evolution of longevity is unknown. Moreover, while studies of large-effect mutants suggest an important role of nutrient sensing pathways in regulating aging, the genetic basis of evolutionary changes in lifespan remains poorly understood. To address these questions, we analyzed the genomes of experimentally evolved Drosophila melanogaster populations subjected to a factorial combination of...

Data from: The early elasmobranch Phoebodus: phylogenetic relationships, ecomorphology, and a new time-scale for shark evolution

Linda Frey, Michael Coates, Michal Ginter, Vachik Hairapetian, Martin Rücklin, Iwan Jerjen & Christian Klug
Anatomical knowledge of early chondrichthyans and estimates of their phylogeny are improving, but many taxa are still known only from microremains. The nearly cosmopolitan and regionally abundant Devonian genus Phoebodus has long been known solely from isolated teeth and fin spines. Here, we report the first skeletal remains of Phoebodus from the Famennian (Late Devonian) of the Maïder region of Morocco, revealing an anguilliform body, specialized braincase, hyoid arch, elongate jaws and rostrum, complementing its...

Affiliation history and age similarity predict alliance formation in adult male bottlenose dolphins

Livia Gerber, Richard Connor, Stephanie King, Simon Allen, Samuel Wittwer, Manuela Bizzozzero, Whitney Friedman, Stephanie Kalberer, William Sherwin, Sonja Wild, Erik Willems & Michael Kruetzen
Male alliances are an intriguing phenomenon in the context of reproduction since, in most taxa, males compete over an indivisible resource, female fertilization. Adult male bottlenose dolphins (Tursiops aduncus) in Shark Bay, Western Australia, form long-term, multi-level alliances to sequester estrus females. These alliances are therefore critical to male reproductive success. Yet, the long-term processes leading to the formation of such complex social bonds are still poorly understood. To identify the criteria by which male...

Data from: Fear of the dark? contrasting impacts of humans vs lynx on diel activity of roe deer across Europe

Nadège C. Bonnot, Ophélie Couriot, Anne Berger, Francesca Cagnacci, Simone Ciuti, Johannes De Groeve, Benedikt Gehr, Marco Heurich, Petter Kjellander, Max Kröschel, Nicolas Morellet, Leif Sönnichsen & A.J. Mark Hewison
Humans, as super predators, can have strong effects on wildlife behaviour, including profound modifications of diel activity patterns. Subsequent to the return of large carnivores to human-modified ecosystems, many prey species have adjusted their spatial behaviour to the contrasting landscapes of fear generated by both their natural predators and anthropogenic pressures. The effects of predation risk on temporal shifts in diel activity of prey, however, remain largely unexplored in human-dominated landscapes. We investigated the influence...

Data from: An analysis of mating biases in trees

Sascha Asif Ismail & Hanna Kokko
Assortative mating is a deviation from random mating based on phenotypic similarity. As it is much better studied in animals than in plants, we investigate for trees whether kinship of realized mating pairs deviates from what is expected from the set of potential mates and use this information to infer mating biases that may result from kin recognition and/or assortative mating. Our analysis covers twenty species of trees for which microsatellite data is available for...

Sci Rep 9, 1–10. https://doi.org/10.1038/s41598-019-53362-4 Abstract: Endocrine data from wild populations provide important insight into social systems. However, obtaining samples for traditional methods involves capture and restraint of animals, and/or pain, which can influence the...

Phylogeography, more than elevation, accounts for sex-chromosome differentiation in Swiss populations of the common frog (Rana temporaria)

Barret Phillips, Nicolas Rodrigues, Alexandra Jansen Van Rensburg & Nicolas Perrin
Sex chromosomes in vertebrates range from highly heteromorphic (as in most birds and mammals) to strictly homomorphic (as in many fishes, amphibians, and non-avian reptiles). Reasons for these contrasted evolutionary trajectories remain unclear, but species such as common frogs with polymorphism in the extent of sex-chromosome differentiation may potentially deliver important clues. By investigating 92 common-frog populations from a wide range of elevations throughout Switzerland, we show that sex-chromosome differentiation strongly correlates with alleles at...

Estimating uncertainty in divergence times among three-spined stickleback clades using the multispecies coalescent

Bohao Fang, Juha Merilä, Michael Matschiner & Paolo Momigliano
Incomplete lineage sorting (ILS) can lead to biased divergence time estimates. To explore if and how ILS has influenced the results of a recent study of worldwide phylogeny of three-spined sticklebacks (Gasterosteus aculeatus), we estimated divergence times among major clades by applying both a concatenation approach and the multispecies coalescent (MSC) model to single-nucleotide polymorphisms. To further test the influence of different calibration strategies, we applied different calibrations to the root and to younger nodes...

Plant responses to diversity-driven selection and associated rhizosphere microbial communities

Cameron Wagg, Terhi Hahl, Sofia Van Moorsel, Marc Schmid, Debra Zuppinger-Dingley & Bernhard Schmid
1. Plant diversity loss can alter plant interactions and rhizosphere microbial communities. These altered interactions in turn exert diversity-driven selection pressures to which plants may respond with phenotypic changes. Diverse plant communities may favour the survival and fitness of individuals with traits that avoid competition. Conversely monocultures may accumulate species-specific pests favouring greater investment in defence traits. Yet it is unknown how altered plant rhizosphere interactions influence the plant diversity-driven selection for altered plant phenotypes....

Intraspecific mating system evolution and its effect on complex male secondary sexual traits: does male-male competition increase selection on size or shape?

Julian Baur, Jeannine Roy, Martin A. Schäfer, Nalini Puniamoorthy, Wolf U. Blanckenhorn & Patrick T. Rohner
Sexual selection is generally held responsible for the exceptional diversity in secondary sexual traits in animals. Mating system evolution is therefore expected to profoundly affect the covariation between secondary sexual traits and mating success. While there is such evidence at the interspecific level, data within species remain scarce. We here investigate sexual selection acting on the exaggerated male fore femur and the male wing in the common and widespread dung flies Sepsis punctum and S....

Data from: Pollen analogues are transported across greater distances in bee-pollinated than in hummingbird-pollinated species of Justicia (Acanthaceae)

Alexander N. Schmidt-Lebuhn, Matthias Muller, Paola Pozo, Francisco Encinas-Viso & Michael Kessler
Several hummingbird-pollinated plant lineages have been demonstrated to show increased rates of diversification compared to related insect-pollinated lineages. It has been argued that this pattern is produced by a higher degree of specialization on part of both hummingbirds and plants. We here test an alternative hypothesis: The often highly territorial hummingbirds may on average carry pollen over shorter distances than other pollinators and drive diversification by reducing gene flow distances. We present experimental data from...

Data from: Does thermal plasticity align with local adaptation? – An interspecific comparison of wing morphology in sepsid flies

Patrick T. Rohner, Jeannine Roy, Martin A. Schäfer, Wolf U. Blanckenhorn & David Berger
Although genetic and plastic responses are sometimes considered as unrelated processes, their phenotypic effects may often align because genetic adaptation is expected to mirror phenotypic plasticity if adaptive, but run counter to it when maladaptive. The magnitude and direction of this alignment has further consequences for both the tempo and mode of adaptation. To better understand the interplay between phenotypic plasticity and genetic change in mediating adaptive phenotypic variation to climate variability, we here quantified...

Data from: Island woodiness underpins accelerated disparification in plant radiations

Nicolai M. Nürk, Guy W. Atchison & Colin E. Hughes
The evolution of secondary (insular) woodiness and the rapid disparification of plant growth forms associated with island radiations show intriguing parallels between oceanic islands and tropical alpine sky islands. However, the evolutionary significance of these phenomena remains poorly understood and the focus of debate. We explore the evolutionary dynamics of species diversification and trait disparification across evolutionary radiations in contrasting island systems compared to their non‐island relatives. We estimate rates of species diversification, growth form...

Data from: The way wear goes – phytolith-based wear on the dentine-enamel system in guinea pigs (Cavia porcellus)

Louise F. Martin, Daniela Winkler, Thomas Tütken, Codron Daryl, Annelies De Cuyper, Jean-Michel Hatt & Marcus Clauss
The effect of phytoliths on tooth wear and function has been contested in studies of animal plant interactions. For herbivores whose occlusal chewing surface consists of enamel ridges in dentine tissue, the phytoliths might first erode the softer dentine, exposing the enamel ridges to different occlusal forces and thus leading to enamel wear. To test this hypothesis, we fed guinea pigs (Cavia porcellus; n=36 in 6 groups) for three weeks exclusively on dry or fresh...

Data from: Cross-species hybridization and the origin of North African date palms

Jonathan M. Flowers, Khaled M. Hazzouri, Muriel Gros-Balthazard, Ziyi Mo, Konstantina Koutroumpa, Andreas Perrakis, Sylvie Ferrand, Hussam S. M. Khierallah, Dorian Q. Fuller, Frederique Aberlenc, Christini Fournaraki & Michael D. Purugganan
Date palm (Phoenix dactylifera L.) is a major fruit crop of arid regions that were domesticated 7,000 y ago in the Near or Middle East. This species is cultivated widely in the Middle East and North Africa, and previous population genetic studies have shown genetic differentiation between these regions. We investigated the evolutionary history of P. dactylifera and its wild relatives by resequencing the genomes of date palm varieties and five of its closest relatives....

Data from: A novel biomechanical approach for animal behaviour recognition using accelerometers

Pritish Chakravarty, Gabriele Cozzi, Arpat Ozgul & Kamiar Aminian
Data from animal‐borne inertial sensors are widely used to investigate several aspects of an animal's life, such as energy expenditure, daily activity patterns and behaviour. Accelerometer data used in conjunction with machine learning algorithms have been the tool of choice for characterising animal behaviour. Although machine learning models perform reasonably well, they may not rely on meaningful features, nor lend themselves to physical interpretation of the classification rules. This lack of interpretability and control over...

Gene flow limits adaptation along steep environmental gradients

Judith Bachmann, Alexandra Jansen Van Rensburg, Maria Cortazar-Chinarro, Anssi Laurila & Josh Van Buskirk
When environmental variation is spatially continuous, dispersing individuals move among nearby sites with similar habitat conditions. But as an environmental gradient becomes steeper, gene flow may connect more divergent habitats, and this is predicted to reduce the slope of the adaptive cline that evolves. We compared quantitative genetic divergence of Rana temporaria frog populations along a 2000-m elevational gradient in eastern Switzerland (new experimental results) with divergence along a 1550-km latitudinal gradient in Fennoscandia (previously...

Capture-recapture data with partially known birth date in four populations of yellow-bellied toads

Hugo Cayuela, Jean-François Lemaître, Eric Bonnaire, Julian Pichenot & Benedikt Schmidt
1. Patterns of actuarial senescence can be highly variable among species. Previous comparative analyses revealed that both age at the onset of senescence and rates of senescence are linked to species position along the fast-slow life-history continuum. As there are few long-term datasets of wild populations with known-age individuals, intraspecific (i.e. between-population) variation in senescence is understudied and limited to comparisons of wild and captive populations of the same species, mostly birds and mammals. 2....
