Pre-adaptation to climate change through topography-driven evolution of traits and their plasticity

Hanne De Kort, Bart Panis, Steven Janssens, Kenny Helsen & Olivier Honnay
1. Climate change will increase the level of drought stress experienced by plant communities, but the spatial distribution of projected changes in dryness remains highly uncertain. Species can, to some extent, deal with climate uncertainty through natural variation in adaptive responses to environmental heterogeneity and predictability. Biodiversity conservation could thus target populations pre-adapted to climatic heterogeneity to anticipate climate uncertainty. Disentangling evolution of trait means vs. trait plasticity, however, requires a sampling design with genetic...

Identification of a queen pheromone mediating the rearing of adult sexuals in the pharaoh ant Monomorium pharaonis

Ricardo Caliari Oliveira
Division of labour between reproductive queens and mostly sterile workers is among the defining characteristics of social insects. Queen-produced chemical signals advertising her presence and fertility status, i.e. queen pheromones, are normally used to assert the queen’s reproductive dominance in the colony. Most queen pheromones identified to date are chemicals that stop the daughter workers from reproducing. Nevertheless, it has long been suggested that queen pheromones could also regulate reproduction in different ways. In some...

European soil seed bank communities across a climate and land-cover gradient

Jan Plue, Hans Van Calster, Inger Auestad, Sofia Basto, Reneé M. Bekker, Hans Henrik Bruun, Richard Chevalier, Guillaume Decocq, Ulf Grandin, Martin Hermy, Hans Jacquemyn, Anna Jakobsson, Rein Kalamees, Rob H. Marrs, Bryndis Marteinsdóttir, Per Milberg, Robin J. Pakeman, Gareth Phoenix, Ken Thompson, Vigdis Vandvik, Markus Wagner, Sara A.O. Cousins, Ove Eriksson, Jamshid Ghorbani, Małgorzata Jankowska-Błaszczuk … & Alistair G. Auffret
This is the data set used for the publication Buffering effects of soil seed banks on plant community composition in response to land use and climate, published in the journal Global Ecology and Biogeography. Aim. Climate and land use are key determinants of biodiversity, with past and ongoing changes posing serious threats to global ecosystems. Unlike most other organism groups, plant species can possess dormant life-history stages such as soil seed banks, which may help...

Data from: Oxidative stress mediates rapid compensatory growth and its costs

Lizanne Janssens & Robby Stoks
1. While oxidative stress has been hypothesized to function both as a constraint on and a cost of growth, its mediatory role in shaping life history is still highly debated. Empirical studies about the role of oxidative stress in shaping growth responses and the associated costs are scarce and the two hypotheses have never been combined in one study. 2. By directly manipulating oxidative stress we tested its role in determining compensatory growth responses and...

Reduced stress defense responses contribute to the higher toxicity of a pesticide under warming

Vienna Delnat, Janne Swaegers, Jana Asselman & Robby Stoks
There is a pressing need to identify the molecular mechanisms underlying the, often magnifying, interactive effects between contaminants and natural stressors. We here test our hypothesis that lower general stress defense responses contribute to synergistic interactions between stressors. We focus on the widespread pattern that many contaminants are more toxic at higher temperatures. Specifically, we tested the effects of an environmentally realistic low-effect and high-effect concentration of the pesticide chlorpyrifos under warming at the gene...

Lazy Robot Control by Relaxation of Motion and Force Constraints

Djordje Vukcevic
Human and robot tasks in household environments include actions such as carrying an object, cleaning a surface, etc. These tasks are performed by means of dexterous manipulation, and for humans, they are straightforward to accomplish. Moreover, humans perform these actions with reasonable accuracy and precision but with much less energy and stress on the actuators (muscles) than the robots do. The high agility in controlling their forces and motions is actually due to "laziness", i.e....

Strong species differences in life-history do not predict oxidative stress physiology or sensitivity to an environmental oxidant

Nedim Tüzün, Sara Debecker & Robby Stoks
1. Species typically align along a fast-slow life-history continuum, yet it is not clear to what extent oxidative stress physiology can be integrated with this continuum to form a ‘pace-of-life syndrome’, especially so in invertebrates. This is important, given the assumed role of oxidative stress in mediating life-history trade-offs, and the prediction that species with a faster pace should be more vulnerable to oxidative stress. 2. We tested whether a species’ life-history pace, here represented...

Optical traits perform equally well as directly-measured functional traits in explaining the impact of an invasive plant on litter decomposition

Kenny Helsen, Elisa Van Cleemput, Leonardo Bassi, Ben Somers & Olivier Honnay
1. Functional traits can help elucidate and predict the impact of invasive plant species on ecosystem functioning. Yet, this approach requires comprehensive and labor-intensive trait collection campaigns, covering intraspecific trait variation of both the invader and native species in the invaded community. One potential way to overcome these logistic constraints is using hyperspectral remote sensing technology to efficiently quantify functional trait values. Although such spectrally derived or ‘optical’ traits are known to closely link to...

Summary of the microsatellite genotyping analysis of 280 C. gariepinus samples originating from eight locations in the Congo basin using five microsatellite markers

Sales, Erika R. Manuli, Julien Thézé, Luiz Almeida, Mariane T. Menezes, Carolina M. Voloch, Marcilio J. Fumagalli, Thaís M. Coletti, Camila A. M. Da Silva, Mariana S. Ramundo, Mariene R. Amorim, Henrique H. Hoeltgebaum, Swapnil Mishra, Mandev S. Gill, Luiz M. Carvalho, Lewis F. Buss … & Nuno R. Faria
Brazil currently has one of the fastest growing SARS-CoV-2 epidemics in the world. Owing to limited available data, assessments of the impact of non-pharmaceutical interventions (NPIs) on virus spread remain challenging. Using a mobility-driven transmission model, we show that NPIs reduced the reproduction number from >3 to 1–1.6 in São Paulo and Rio de Janeiro. Sequencing of 427 new genomes and analysis of a geographically representative genomic dataset identified >100 international virus introductions in Brazil....

Famine related mortality in early life and accelerated life histories in 19th Century Belgium

Katharina Pink, Robert Quinlan & Saskia Hin
Density-dependent and extrinsic mortality are predicted to accelerate reproductive maturation. The first 5 years of life is a proposed sensitive period for life-history regulation. This study examines the ways in which local mortality during this sensitive period was related to subsequent marriage timing in 19th Century Belgium (N women= 11,892; N men=14,140). Local mortality during the sensitive period was inversely associated with age at first marriage for men and women controlling for literacy, occupational status,...

Seasonal time constraints shape life history, physiology and behaviour independently, and decouple a behavioural syndrome in a damselfly

Nedim Tüzün, Beste Başak Savaşçı & Robby Stoks
The integration of traits into 'syndromes' has been suggested as a useful framework to advance insights in trait responses to environmental stressors. Yet, how stressors shape the consistency (‘repeatability’) of traits and their covariation at the individual level remains debated. We studied how seasonal time constraints shape trait repeatability and integration of life-history, behavioural, and physiological traits along a fast-slow continuum, using the ‘pace-of-life syndrome’ as a framework. We manipulated the photoperiod during the larval...

Data from: Live fast, die old: oxidative stress as a potential mediator of an unexpected life-history evolution

Nedim Tüzün, Marjan De Block & Robby Stoks
Intraspecific latitudinal patterns in life history are well documented, yet underlying mechanisms of such patterns are poorly understood. To advance our insights in the evolution of latitudinal differences in two key traits, growth rate and lifespan, we evaluated the potential costs of rapid growth in terms of reduced adult lifespan, and the mediatory role of oxidative stress. We studied latitudinal differentiation in routine and experimentally increased (compensatory) larval growth rates, and in adult lifespan under...

Volatiles of bacteria associated with parasitoid habitats elicit distinct olfactory responses in an aphid parasitoid and its hyperparasitoid

1. To locate mating partners and essential resources such as food, oviposition sites and shelter, insects rely to a large extent on chemical cues. While most research has focused on cues derived from plants and insects, there is mounting evidence that indicates that microorganisms emit volatile compounds that may play an important role in insect behaviour. 2. In this study, we assessed how volatile compounds emitted by phylogenetically diverse bacteria affected the olfactory response of...

Inter- and intraspecific trait variation shape multidimensional trait overlap between two plant invaders and the invaded communities

Kenny Helsen, Elisa Van Cleemput, Leonardo Bassi, Bente Graae, Ben Somers, Benjamin Blonder & Olivier Honnay
Invader success and ecosystem impact are both expected to be largely driven by the functional trait distinctiveness of the resident species relative to the invaded communities. To understand the importance of trait distinctiveness for plant invasions, and the native community’s trait response to the invasion, it is key to measure multiple traits simultaneously, and to incorporate intraspecific trait variation. Here we explored multidimensional patterns of inter- and intraspecific trait variation during the invasion of two...

Innate preference hierarchies coupled with adult experience, rather than larval imprinting or transgenerational acclimation, determine host plant use in Pieris rapae

Hampus Petrén, Gabriele Gloder, Diana Posledovich, Christer Wiklund & Magne Friberg
The evolution of host range drives diversification in phytophagous insects, and understanding the female oviposition choices is pivotal for understanding host specialization. One controversial mechanism for female host choice is Hopkins’ host selection principle, where females are predicted to increase their preference for the host species they were feeding upon as larvae. A recent hypothesis posits that such larval imprinting is especially adaptive in combination with anticipatory transgenerational acclimation, so that females both allocate and...

Data from: Bacterial phylogeny predicts volatile organic compound composition and olfactory response of an aphid parasitoid

Tim Goelen, Islam Sobhy, Christophe Vanderaa, Felix Wäckers, Hans Rediers, Tom Wenseleers, Hans Jacquemyn & Bart Lievens
There is increasing evidence that microorganisms emit a wide range of volatile compounds (mVOCs, microbial volatile organic compounds) that act as insect semiochemicals, and therefore play an important role in insect behaviour. Although it is generally believed that phylogenetically closely related microbes tend to have similar phenotypic characteristics and therefore may elicit similar responses in insects, currently little is known about whether the evolutionary history and phylogenetic relationships among microorganisms have an impact on insect-microbe...

Transcriptome assembly for: Genetic compensation rather than genetic assimilation drives the evolution of plasticity in response to mild warming across latitudes in a damselfly

Janne Swaegers, Katina Spanier & Robby Stoks
Global warming is causing plastic and evolutionary changes in the phenotypes of ectotherms. Yet, we have limited knowledge on how the interplay between plasticity and evolution shapes thermal responses and underlying gene expression patterns. We assessed thermal reaction norm patterns across the transcriptome and identified associated molecular pathways in northern and southern populations of the damselfly Ischnura elegans. Larvae were reared in a common garden experiment at the mean summer water temperatures experienced at the...

Support for the climatic variability hypothesis depends on the type of thermal plasticity: lessons from predation rates

Ying-Jie Wang, Robby Stoks, Arnaud Sentis & Nedim Tüzün
Plastic and evolutionary changes in traits related to biotic interactions are crucial for the local persistence of populations under global warming. Yet, how acute and developmental thermal plasticity evolve and shape predation rates has been poorly studied, especially in the context of latitude-driven thermal evolution. A powerful predictive framework is given by the climatic variability hypothesis (CVH) stating that thermal plasticity and acclimation capacity evolve to be higher in high-latitude populations because these are exposed...

Conservation status assessment of banana crop wild relatives using species distribution modelling

Arne Mertens
Aim: Crop wild relatives (CWR) are an essential source of genetic material for the improvement of certain traits in related crop species. Despite their importance, increasing public, scientific and political support, large gaps exist in the amount of genetic material collected and conserved of many CWR. Here, we construct a dataset on the distribution of wild banana species (Musa spp.) and assess their risk and conservation status. We deal with the questions (1) what areas...
