Data from: Muscle-tendon unit length changes differ between young and adult sprinters in first stance phase of sprint running

Jeroen Aeles, Ilse Jonkers, Sofie Debaere, Christophe Delecluse & Benedicte Vanwanseele
The aim of this study was to compare young and adult sprinters on several biomechanical parameters that were previously highlighted as performance-related and to determine the behaviour of several muscle-tendon units (MTU) in the first stance phase following a block start in sprint running. The ground reaction force (GRF) and kinematic data were collected from 16 adult and 21 young well-trained sprinters. No difference between the groups was found in some of the previously-highlighted performance-related...

Data from: Rapid evolution of larval life history, adult immune function and flight muscles in a poleward moving damselfly

Lieven Therry, Viktor Nilsson-Örtman, Dries Bonte & Robby Stoks
Although a growing number of studies have documented the evolution of adult dispersal-related traits at the range edge of poleward-expanding species, we know little about evolutionary changes in immune function or traits expressed by nondispersing larvae. We investigated differentiation in larval (growth and development) and adult traits (immune function and flight-related traits) between replicated core and edge populations of the poleward-moving damselfly Coenagrion scitulum. These traits were measured on individuals reared in a common garden...

Data from: Environment not dispersal limitation drives clonal composition of arctic Daphnia in a recently deglaciated area

Tsegazeabe Hadush Haileselasie, Joachim Mergeay, Lawrence J. Weider, Ruben Sommaruga, Thomas A. Davidson, Mariana Meerhoff, Hartmut Arndt, Klaus Jürgens, Erik Jeppesen & Luc De Meester
One of the most prominent manifestations of the ongoing climate warming is the retreat of glaciers and ice sheets around the world. Retreating glaciers result in the formation of new ponds and lakes, which are available for colonization. The gradual appearance of these new habitat patches allows us to determine to what extent the composition of asexual Daphnia (water flea) populations is affected by environmental drivers versus dispersal limitation. Here we used a landscape genetics...

Data from: Regional environmental pressure influences population differentiation in turbot (Scophthalmus maximus)

S. G. Vandamme, G. E. Maes, J. A. M. Raeymaekers, K. Cottenie, A. K. Imsland, B. Hellemans, G. Lacroix, E. Mac Aoidh, J. T. Martinsohn, P. Martínez, J. Robbens, R. Vilas & F. A. M. Volckaert
Unravelling the factors shaping the genetic structure of mobile marine species is challenging due to the high potential for gene flow. However, genetic inference can be greatly enhanced by increasing the genomic, geographic or environmental resolution of population genetic studies. Here we investigated the population structure of turbot (Scophthalmus maximus) by screening 17 random and gene-linked markers in 999 individuals at 290 geographical locations throughout the Northeast Atlantic Ocean. A seascape genetics approach with the...

Data from: Quantifying population divergence on short timescales

Joost A. M. Raeymaekers, Luc Lens, Frederik Van Den Broeck, Stefan Van Dongen & Filip A. M. Volckaert
Quantifying the contribution of the various processes that influence population genetic structure is important, but difficult. One of the reasons is that no single measure appropriately quantifies all aspects of genetic structure. An increasing number of studies is analyzing population structure using the statistic D, which measures genetic differentiation, next to GST, which is the standardized variance in allele frequencies among populations. Few studies have evaluated which statistic is most appropriate in particular situations. In...

Data from: Parasite escape through trophic specialization in a species flock

Pascal I. Hablützel, Maarten P.M. Vanhove, Pablo Deschepper, Arnout F. Grégoir, Anna K. Roose, Filip A.M. Volckaert & Joost A.M. Raeymaekers
Adaptive radiation occurs when species diversify rapidly to occupy an array of ecological niches. Since opportunities for parasite infection and transmission may greatly vary among these niches, adaptive radiation is expected to be associated with a turnover of the parasite community. As major agents of natural and sexual selection, parasites may play a central role in host diversification. The study of parasite turnover may thus be of general relevance and could significantly improve our understanding...

Data from: Biotic predictors complement models of bat and bird responses to climate and tree diversity in European forests

Luc Barbaro, Eric Allan, Evy Ampoorter, Bastien Castagneyrol, Yohan Charbonnier, Hans De Wandeler, Christian Kerbiriou, Harriet Milligan, Aude Vialatte, Monique Carnol, Marc Deconchat, Pallieter De Smedt, Herve Jactel, Julia Koricheva, Isabelle Le Viol, Bart Muys, Michael Scherer-Lorenzen, Kris Verheyen & Fons Van Der Plas
Bats and birds are key providers of ecosystem services in forests. How climate and habitat jointly shape their communities is well studied, but whether biotic predictors from other trophic levels may improve bird and bat diversity models is less known, especially across large bioclimatic gradients. Here, we achieved multi-taxa surveys in 209 mature forests replicated in six European countries from Spain to Finland, to investigate the importance of biotic predictors (i.e., the abundance or activity...

Data from:Microgeographic differentiation in thermal performance curves between rural and urban populations of an aquatic insect

Nedim Tüzün, Lin Op De Beeck, Kristien I. Brans, Lizanne Janssens & Robby Stoks
The rapidly increasing rate of urbanization has a major impact on the ecology and evolution of species. While increased temperatures are a key aspect of urbanization (“urban heat islands”), we have very limited knowledge whether this generates differentiation in thermal responses between rural and urban populations. In a common garden experiment, we compared the thermal performance curves (TPCs) for growth rate and mortality in larvae of the damselfly Coenagrion puella from three urban and three...

Data from: Understanding past population dynamics: Bayesian coalescent-based modeling with covariates

Mandev S. Gill, Philippe Lemey, Shannon N. Bennett, Roman Biek & Marc A. Suchard
Effective population size characterizes the genetic variability in a population and is a parameter of paramount importance in population genetics and evolutionary biology. Kingman's coalescent process enables inference of past population dynamics directly from molecular sequence data, and researchers have developed a number of flexible coalescent-based models for Bayesian nonparametric estimation of the effective population size as a function of time. Major goals of demographic reconstruction include identifying driving factors of effective population size, and...

Data from: Signatures of selection in the three-spined stickleback along a small scale brackish water - freshwater transition zone

Nellie Konijnendijk, Takahito Shikano, Dorien Daneels, Filip A. M. Volckaert, Joost A. M. Raeymaekers & Filip A.M. Volckaert
Local adaptation is often obvious when gene flow is impeded, such as observed at large spatial scales and across strong ecological contrasts. However, it becomes less certain at small scales such as between adjacent populations or across weak ecological contrasts, when gene flow is strong. While studies on genomic adaptation tend to focus on the former, less is known about the genomic targets of natural selection in the latter situation. In this study, we investigate...

Data from: Recolonization after habitat restoration leads to decreased genetic variation in populations of a terrestrial orchid

Katrien Vandepitte, Alessandro S. Gristina, Koen De Hert, Tine Meekers, Isabel Roldán-Ruiz & Olivier Honnay
Colonization is crucial to habitat restoration projects that rely on the spontaneous regeneration of the original vegetation. However, as a previously declining plant species spreads again, the likelihood of founder effects increases through recurrent population founding and associated serial bottlenecks. We related AFLP genetic variation and fitness of all extant populations of the outcrossing terrestrial orchid Dactylorhiza incarnata in an isolated coastal dune complex to colonization history. Around 1970, D. incarnata suffered a severe bottleneck...

Data from: Rapid range expansion increases genetic differentiation while causing limited reduction in genetic diversity in a damselfly

Janne Swaegers, Joachim Mergeay, Lieven Therry, Maarten H. D. Larmuseau, Dries Bonte & Robby Stoks
Many ectothermic species are currently expanding their geographic range due to global warming. This can modify the population genetic diversity and structure of these species because of genetic drift during the colonization of new areas. Although the genetic signatures of historical range expansions have been investigated in an array of species, the genetic consequences of natural, contemporary range expansions have received little attention, with the only studies available focusing on range expansions along a narrow...

Data from: Type Maastrichtian gastropod faunas evidencing rapid ecosystem recovery following the Cretaceous-Palaeogene boundary

Johan Vellekoop, Kris Van Tilborgh, Paul Van Knippenberg, John Jagt, Peter Stassen, Stijn Goolaerts & Robert Speijer
The study of the global mass extinction event at the Cretaceous–Palaeogene (K/Pg) boundary can aid in understanding patterns of selective extinction and survival, and dynamics of ecosystem recovery. Outcrops in the Maastrichtian type area (southeast Netherlands, northeast Belgium) comprise an exceptionally expanded K/Pg boundary succession that offers a unique opportunity to study marine ecosystem recovery within the first thousands of years following the mass extinction event. A quantitative analyses was performed on systematically sampled macrofossils...

Data from: Climate change increases ecogeographic isolation between closely related plants

Karl J. Duffy & Hans Jacquemyn
1. Ecogeographic isolation is a fundamental prezygotic barrier to reproduction and a step toward diversification in flowering plants. However, whether ecogeographic isolation acts as a reproductive barrier between species and thus as a mechanism for species divergence is unclear and is expected to change as species distributions shift under climate change. 2. Using a Maxent framework, we quantified the extent of ecogeographic isolation of nine closely related species of the European plant genus Pulmonaria, which...

Data from: Parallel evolution and adaptation to environmental factors in a marine flatfish: implications for fisheries and aquaculture management of the turbot (Scophthalmus maximus)

Fernanda Dotti Do Prado, Manuel Vera, Miguel Hermida, Carmen Bouza, Belén G. Pardo, Román Vilas, Andrés Blanco, Carlos Fernández, Francesco Maroso, Gregory E. Maes, Cemal Turan, Filip A.M. Volckaert, John B. Taggart, Adrian Carr, Rob Ogden, Einar E. Nielsen, The Aquatrace Consortium, Paulino Martínez & Filip A. M. Volckaert
Unraveling adaptive genetic variation represents, in addition to the estimate of population demographic parameters, a cornerstone for the management of aquatic natural living resources, which in turn, represent the raw material for breeding programs. The turbot (Scophthalmus maximus) is a marine flatfish of high commercial value living on the European continental shelf. While wild populations are declining, aquaculture is flourishing in Southern Europe. We evaluated the genetic structure of turbot throughout its natural distribution range...

Data from: Synchronous diversification of Sulawesi's iconic artiodactyls driven by recent geological events

Laurent A. F. Frantz, Anna Rudzinski, Abang Mansyursyah Surya Nugraha, Allowen Evin, James Burton, Ardern Hulme-Beaman, Anna Linderholm, Ross Barnett, Rodrigo Vega, Evan K. Irving-Pease, James Haile, Richard Allen, Kristin Leus, Jill Shephard, Mia Hillyer, Sarah Gillemot, Jeroen Van Den Hurk, Sharron Ogle, Cristina Atofanei, Mark G. Thomas, Friederike Johansson, Abdul Haris Mustari, John Williams, Kusdiantoro Mohamad, Chandramaya Siska Damayanti … & Greger Larson
The high degree of endemism on Sulawesi has previously been suggested to have vicariant origins, dating back 40 Myr ago. Recent studies, however, suggest that much of Sulawesi’s fauna assembled over the last 15 Myr. Here, we test the hypothesis that more recent uplift of previously submerged portions of land on Sulawesi promoted diversification, and that much of its faunal assemblage is much younger than the island itself. To do so, we combined palaeogeographical reconstructions...

Data from: Integrating the pace-of-life syndrome across species, sexes and individuals: covariation of life history and personality under pesticide exposure

Sara Debecker, Iago Sanmartín-Villar, Miguel De Guinea-Luengo, Adolfo Cordero-Rivera & Robby Stoks
The pace-of-life syndrome (POLS) hypothesis integrates covariation of life-history traits along a fast–slow continuum and covariation of behavioural traits along a proactive–reactive personality continuum. Few studies have investigated these predicted life-history/personality associations among species and between sexes. Furthermore, whether and how contaminants interfere with POLS patterns remains unexplored. We tested for covariation patterns in life history and in behaviour, and for life-history/personality covariation among species, among individuals within species and between sexes. Moreover, we investigated...

Data from: Nectar bacteria affect life history of a generalist aphid parasitoid by altering nectar chemistry

Marijke Lenaerts, Tim Goelen, Caro Paulussen, Beatriz Herrera-Malaver, Jan Steensels, Wim Van Den Ende, Kevin Verstrepen, Felix Wäckers, Hans Jacquemyn & Bart Lievens
1. Nectar is a crucial energy resource that strongly mediates the interactions between plants and animal pollinators or plant defenders. Previous research has shown that nectar is commonly colonized by microorganisms, most commonly bacteria and yeasts, which can have a strong impact on nectar chemistry. However, at present little is known about the effects of microorganisms on the fitness of animals feeding on nectar. 2. We used three nectar bacteria representing different metabolic groups (Asaia...

Data from: Overyielding in young tree plantations is driven by local complementarity and selection effects related to shade tolerance

Thomas Van De Peer, Kris Verheyen, Quentin Ponette, Nuri Nurlaila Setiawan & Bart Muys
1. Overyielding in mixed-species forests has been demonstrated in a vast body of literature, and the focus of functional biodiversity research is now shifting towards a mechanistic understanding of these observations. 2. We explored diversity-productivity relationships (DPRs) at two sites of a large-scale tree diversity experiment, with benign (Zed) and harsh (Ged) environmental conditions for plantation establishment. Additive partitioning methodologies were adopted to detect phenomenological patterns in the productivity data, and the trait structure of...

Data from: Decrease in diversity and changes in community composition of arbuscular mycorrhizal fungi in roots of apple trees with increasing orchard management intensity across a regional scale

Maarten Van Geel, Bart Lievens & Olivier Honnay
Understanding which factors drive the diversity and community composition of arbuscular mycorrhizal fungi (AMF) is important due to the role of these soil microorganisms in ecosystem functioning and current environmental threats to AMF biodiversity. Additionally, in agro-ecosystems, this knowledge may help to evaluate their use in making agriculture more sustainable. Here, we used 454-pyrosequencing of small subunit rRNA gene amplicons to quantify AMF diversity and community composition in the roots of cultivated apple trees across...

Data from: Sex change and effective population size: implications for population genetic studies in marine fish

Ilaria Coscia, Julien Chopelet, Robin S. Waples, Bruce Mann & Stefano Mariani
Large variance in reproductive success is the primary factor that reduces effective population size (Ne) in natural populations. In sequentially hermaphroditic (sex-changing) fish, the sex ratio is typically skewed and biased towards the 'first' sex, while reproductive success increases considerably after sex change. Therefore, sex-changing fish populations are theoretically expected to have lower Ne than gonochorists (separate sexes), assuming all other parameters are essentially equal. In this study, we estimate Ne from genetic data collected...

Data from: Thermal evolution offsets the elevated toxicity of a contaminant under warming: a resurrection study in Daphnia magna

Chao Zhang, Mieke Jansen, Luc De Meester & Robby Stoks
Synergistic interactions between temperature and contaminants are a major challenge for ecological risk assessment, especially under global warming. While thermal evolution may increase the ability to deal with warming, it is unknown whether it may also affect the ability to deal with the many contaminants that are more toxic at higher temperatures. We investigated how evolution of genetic adaptation to warming affected the interactions between warming and a novel stressor: zinc oxide nanoparticles (nZnO) in...

Data from: Distinctive fungal communities in an obligate African ant-plant mutualism

Christopher C.M. Baker, Dino J. Martins, Julianne N. Pelaez, Johan P.J. Billen, Anne Pringle, Megan E. Frederickson, Naomi E. Pierce, Christopher C. M. Baker & Johan P. J. Billen
Three ant species nest obligately in the swollen-thorn domatia of the African ant-plant Vachellia (Acacia) drepanolobium, a model system for the study of ant-defence mutualisms and species coexistence. Here we report on the characteristic fungal communities generated by these ant species in their domatia. First, we describe behavioural differences between the ant species when presented with a cultured fungal isolate in the laboratory. Second, we use DNA metabarcoding to show that each ant species has...

Data from: Specialized mutualisms may constrain the geographical distribution of flowering plants

Karl J. Duffy & Steven D. Johnson
It is commonly assumed that the geographical distributions of plants are governed mainly by abiotic variables. However, interactions with other organisms, such as pollinators, also have the potential to influence plant distributions. To investigate this, we developed niche models for 32 plant taxa that have specialized pollination systems and which are native to a biodiversity hotspot (South Africa). We found that the distributions of these taxa are best explained by a combination of biotic (pollinators)...

Data from: DNA barcoding fishes from the Congo and the Lower Guinean provinces: assembling a reference library for poorly inventoried fauna

Gontran Sonet, Jos Snoeks, Zoltan T. Nagy, Emmanuel Vreven, Gert Boden, Floris C. Breman, Eva Decru, Mark Hanssens, Armel Ibala Zamba, Kurt Jordaens, Victor Mamonekene, Tobias Musschoot, Jeroen Van Houdt, Maarten Van Steenberge, Soleil Lunkayilakio Wamuini & Erik Verheyen
The Congolese and Lower Guinean ichthyological provinces are understudied hotspots of the global fish diversity. Here, we barcoded 741 specimens from the Lower and Middle Congo River and from three major drainage basins of the Lower Guinean ichthyological province, Kouilou-Niari, Nyanga and Ogowe. We identified 195 morphospecies belonging to 82 genera and 25 families. Most morphospecies (92.8%) corresponded to distinct clusters of DNA barcodes. Of the four morphospecies present in both neighbouring ichthyological provinces, only...
