Data from: Evolutionary epidemiology of schistosomiasis: linking parasite genetics with disease phenotype in humans

Tine Huyse, Nele A.M. Boon, Frederik Van Den Broeck, Moustapha Mbow, Anurag Chaturvedi, Lynn Meurs, Filip A.M. Volckaert & Katja Polman
Here we assess the role of parasite genetic variation in host disease phenotype in human schistosomiasis by implementing concepts and techniques from environmental association analysis in evolutionary epidemiology. Schistosomiasis is a tropical disease that affects more than 200 million people worldwide and is caused by parasitic flatworms belonging to the genus Schistosoma. While the role of host genetics has been extensively studied and demonstrated, nothing is yet known on the contribution of parasite genetic variation...

Data from: Sexual selection reinforces a higher flight endurance in urban damselflies

Nedim Tüzün, Lin Op De Beeck & Robby Stoks
Urbanisation is among the most important and globally rapidly increasing anthropogenic processes, and is known to drive rapid evolution. Habitats in urbanised areas typically consist of small, fragmented and isolated patches, which is expected to select for a better locomotor performance, along with its underlying morphological traits. This, in turn, is expected to cause differentiation in selection regimes, as populations with different frequency distributions for a given trait will span different parts of the species’...

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: 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: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: 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: 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: Thermal tolerance in the keystone species Daphnia magna –a candidate gene and an outlier analysis approach

Mieke Jansen, Aurora N. Geerts, Alfredo Rago, Katina I. Spanier, Carla Denis, Luc De Meester & Luisa Orsini
Changes in temperature have occurred throughout Earth’s history. However, current warming trends exacerbated by human activities impose severe and rapid loss of biodiversity. Although understanding the mechanisms orchestrating organismal response to climate change is important, remarkably few studies document their role in nature. This is because only few systems enable the combined analysis of genetic and plastic responses to environmental change over long time-spans. Here, we characterize genetic and plastic responses to temperature increase in...

Data from: Founder effects determine the genetic structure of the water flea Daphnia in Ethiopian reservoirs

Tsegazeabe Hadush Haileselasie, Joachim Mergeay, Joost Vanoverbeke, Luisa Orsini & Luc De Meester
Founder effects introduce stochasticity in the genetic structure of species at the regional scale. To the extent that founder effects are important, they will result in a reduced signature of space, time, and environmental variation in landscape genetic data. We studied the metapopulation genetic structure of recently founded populations of the microcrustacean Daphnia sinensis in 10 Ethiopian water reservoirs. We used three different approaches to estimate the number of effective founders and applied them to...

Data from: Adaptive and non-adaptive divergence in a common landscape

Joost A. M. Raeymaekers, Anurag Chaturvedi, Pascal I. Hablützel, Io Verdonck, Bart Hellemans, Gregory E. Maes, Luc De Meester & Filip A. M. Volckaert
Species in a common landscape often face similar selective environments. The capacity of organisms to adapt to these environments may be largely species specific. Quantifying shared and unique adaptive responses across species within landscapes may thus improve our understanding of landscape-moderated biodiversity patterns. Here we test to what extent populations of two coexisting and phylogenetically related fishes—three-spined and nine-spined stickleback—differ in the strength and nature of neutral and adaptive divergence along a salinity gradient. Phenotypic...

Data from: The palaeogenetics of cat dispersal in the ancient world

Claudio Ottoni, Wim Van Neer, Bea De Cupere, Julien Daligault, Silvia Guimaraes, Joris Peters, Nikolai Spassov, Mary E. Prendergast, Nicole Boivin, Arturo Morales-Muñiz, Adrian Bălăşescu, Cornelia Becker, Norbert Benecke, Adina Boroneant, Hijlke Buitenhuis, Jwana Chahoud, Alison Crowther, Laura Llorente, Nina Manaseryan, Hervé Monchot, Vedat Onart, Marta Osypińska, Olivier Putelat, Eréndira M. Quintana Morales, Jacqueline Studer … & Eva-Maria Geigl
The cat has long been important to human societies as a pest-control agent, object of symbolic value and companion animal, but little is known about its domestication process and early anthropogenic dispersal. Here we show, using ancient DNA analysis of geographically and temporally widespread archaeological cat remains, that both the Near Eastern and Egyptian populations of Felis silvestris lybica contributed to the gene pool of the domestic cat at different historical times. While the cat’s...

Data from: Reconstructing Asian faunal introductions to eastern Africa from multi-proxy biomolecular and archaeological datasets

Horton, Stephanie Wynne-Jones, Jeffrey Fleisher, Chantal Radimilahy, Henry Wright … & Mark Horton
Human-mediated biological exchange has had global social and ecological impacts. In sub-Saharan Africa, several domestic and commensal animals were introduced from Asia in the pre-modern period; however, the timing and nature of these introductions remain contentious. One model supports introduction to the eastern African coast after the mid-first millennium CE, while another posits introduction dating back to 3000 BCE. These distinct scenarios have implications for understanding the emergence of long-distance maritime connectivity, and the ecological...

Data from: Phylogenetic factor analysis

Max R. Tolkoff, Michael E. Alfaro, Guy Baele, Philippe Lemey & Marc A. Suchard
Phylogenetic comparative methods explore the relationships between quantitative traits adjusting for shared evolutionary history. This adjustment often occurs through a Brownian diffusion process along the branches of the phylogeny that generates model residuals or the traits themselves. For high-dimensional traits, inferring all pair-wise correlations within the multivariate diffusion is limiting. To circumvent this problem, we propose phylogenetic factor analysis (PFA) that assumes a small unknown number of independent evolutionary factors arise along the phylogeny and...

Data from: Negative effects of pesticides under global warming can be counteracted by a higher degradation rate and thermal adaptation

Lin Op De Beeck, Julie Verheyen, Kent Olsen & Robby Stoks
1. An alarming finding for biodiversity is that global warming and pesticides often interact synergistically. Yet, this synergism may not capture the full picture because two counteracting processes may reduce the higher impact of pesticides under warming: higher pesticide degradation in the environment and thermal adaptation of populations. 2. We tested for the effects of warming and multiple pulses of the insecticide chlorpyrifos on life history and fitness-related physiological traits in the damselfly Ischnura elegans....

Data from: Intra- and interspecific niche variation as reconstructed from stable isotopes in two ecologically different Ethiopian Rift Valley lakes

Pieter Lemmens, Fassil E. Teffera, Maarten Wynants, Lynn Govaert, Jozef Deckers, Hans Bauer, Feleke Woldeyes, Luc Brendonck, Steven Bouillon & Luc De Meester
1. The concept of species niches has enhanced our understanding of community assembly and food web structure in a variety of ecosystem types. Niche-based species sorting profoundly determines community composition along strong environmental gradients, while interspecific interactions tend to be more important within habitats at local spatial scales. The role of intraspecific niche variation in community assembly and ecosystem functioning has only recently been highlighted. 2. The present study undertakes a quantitative comparison of the...

Data from: Pathways to fitness: carry-over effects of late hatching and urbanisation on lifetime mating success

Nedim Tüzün & Robby Stoks
Life history theory and most empirical studies assume carry-over effects of larval conditions to shape adult fitness through their impact on metamorphic traits (age and mass at metamorphosis). Yet, very few formal tests of this connection across metamorphosis exist, because this entails longitudinal studies from the egg stage and requires measuring fitness in (semi)natural conditions. In a longitudinal one-year common-garden rearing experiment consisting of an outdoor microcosm part for the larval stage and a large...

Data from: Rapid evolution leads to differential population dynamics and top-down control in resurrected Daphnia populations

Eyerusalem Goitom, Laurens Kilsdonk, Kristien Brans, Mieke Jansen, Pieter Lemmens, Luc De Meester & Laurens J. Kilsdonk
There is growing evidence of rapid genetic adaptation of natural populations to environmental change, opening the perspective that evolutionary trait change may subsequently impact ecological processes such as population dynamics, community composition and ecosystem functioning. To study such eco-evolutionary feedbacks in natural populations, however, requires samples across time. Here we capitalize on a resurrection ecology study that documented rapid and adaptive evolution in a natural population of the water flea Daphnia magna in response to...

Data from: \"ABC\" - the Awareness-Body-Chart: a New Tool Assessing Body Awareness

Ursula Danner, Alexander Avian, Tanja Macheiner, Beate Salchinger, Nina Dalkner, Frederike T. Fellendorf, Armin Birner, Susanne A. Bengesser, Martina Platzer, Hans-Peter Kapfhammer, Michel Probst & Eva Z. Reininghaus
Background: Despite the importance of body awareness for health and well-being there is still a lack of valid assessment tools to scan proper body awareness. To respond to the limitations of questionnaires (reading/interpretation problems of subjects) the Awareness-Body-Chart (ABC) was designed to assess body awareness by colouring 51 regions according to their awareness. The objective of this study was to investigate the psychometric characteristics of the ABC. Methods: In a questionnaire-study, 106 students in Graz...

Data from: Covert deformed wing virus infections have long-term deleterious effects on honeybee foraging and survival

Kristof Benaets, Anneleen Van Geystelen, Dries Cardoen, Lina De Smet, Dirk C. De Graaf, Liliane Schoofs, Maarten H.D. Larmuseau, Laura E. Brettell, Stephen J. Martin, Tom Wenseleers & Maarten H. D. Larmuseau
Several studies have suggested that covert stressors can contribute to bee colony declines. Here we provide a novel case study and show using radiofrequency identification tracking technology that covert deformed wing virus (DWV) infections in adult honeybee workers seriously impact long-term foraging and survival under natural foraging conditions. In particular, our experiments show that adult workers injected with low doses of DWV experienced increased mortality rates, that DWV caused workers to start foraging at a...

Data from: Kin discrimination increases with odor distance in the German cockroach

Mathieu Lihoreau, Colette Rivault & Jelle S. Van Zweden
Kin recognition mediates altruistic behavior and inbreeding avoidance in many animal societies. So far, evidence for accurate kin recognition, when individuals distinguish fine scale differences in genetic relatedness, in social insects is mixed. Although this ability should be counter selected to reduce risks of nepotism in eusocial colonies, accurate kin recognition may be beneficial in less integrated societies where genetic conflicts are reduced. Here we show that gregarious cockroaches Blattella germanica discriminate multiple levels of...
