Size-mediated priority effects are trait-dependent and consistent across latitudes in a damselfly

Mateusz Raczyński, Robby Stoks, Frank Johansson & Szymon Sniegula
Variation in hatching time (phenology) might cause size differences within populations resulting in size-mediated priority effects (SMPEs) shaping intraspecific interactions. These phenology-driven effects potentially can be strengthened by seasonal time constraints caused by a short growth season, and depend on latitude. Here the single and combined effects of phenology and latitude-associated time constraints on SMPEs in larvae of an aquatic insect, the damselfly Lestes sponsa, are studied. We did so by rearing larvae in groups...

Otolith microstructures analysis of juveniles sole (Solea solea L.) in the Southern North Sea

Silvia Paoletti, Karen Bekaert, Kris Hostens & Filip Volckaert
The dataset contains the individual fish and otolith measurements necessary to analyse the early-life history stages of juvenile common sole in the Southern North Sea. Samples were collected at three major nursery grounds, the Belgian coast, the Dutch coast and the UK coast between 2013 and 2016. The analysis of the otolith microstructures (daily growth rings) allows the back calculation of hatching and settlement periods as well as the investigation of growth conditions. The dataset...

Data from: Host-parasite dynamics shaped by temperature and genotype: quantifying the role of underlying vital rates

Marjolein Bruijning, Erlend Fossen, Eelke Jongejans, Héléne Vanvelk, Joost Raeymaekers, Lynn Govaert, Kristien Brans, Sigurd Einum & Luc De Meester
1. Global warming challenges the persistence of local populations, not only through heat-induced stress, but also through indirect biotic changes. We study the interactive effects of temperature, competition and parasitism in the water flea Daphnia magna. 2. We carried out a common garden experiment monitoring the dynamics of Daphnia populations along a temperature gradient. Halfway through the experiment, all populations became infected with the ectoparasite Amoebidium parasiticum, enabling us to study interactive effects of temperature...

Resurrecting the metabolome: Rapid evolution magnifies the metabolomic plasticity to predation in a natural Daphnia population

Chao Zhang, Martin Jones, Lynn Govaert, Mark Viant, Luc De Meester & Robby Stoks
Populations rely on already present plastic responses (ancestral plasticity) and evolution (including both evolution of mean trait values, constitutive evolution, and evolution of plasticity) to adapt to novel environmental conditions. Because of the lack of evidence from natural populations, controversy remains regarding the interplay between ancestral plasticity and rapid evolution in driving responses to new stressors. We addressed this topic at the level of the metabolome utilizing a resurrected natural population of the water flea...

The role of dispersal limitation and reforestation in shaping the distributional shift of a forest herb under climate change

Frederik Van Daele, Olivier Honnay & Hanne De Kort
Aim: Forest herbs might be unable to track shifts in habitat suitability due to rapid climate change and habitat fragmentation. In this study, we quantified the role of dispersal limitation and the potential mitigating effect of large-scale reforestation on the redistribution of the herbaceous forest plant species Primula elatior under climate change. Location: Europe Methods: High resolution (100 m) landscape-scale and macro-climatic variables were combined to predict range-wide habitat suitability using Maxent. Dispersal limitation was...

Differentially methylated cytosines in Fragaria vesca

Hanne De Kort
Epigenetic change is considered relatively unstable and short-lived, questioning its contribution to long-term adaptive potential. However, epigenetic modifications can accumulate in the presence of environmental stress, resulting in beneficial epigenetic memories where environments are challenging. Diverging epigenetic memories have been observed across large spatial scales, and can persist through multiple generations even in the absence of the causative environmental stressor. It is unknown, however, to what extent epigenetic variation contributes to fine-scale population structure and...

Perceptual correlates of homosynaptic long term potentiation in human nociceptive pathways: a replication study

Emanuel Van Den Broeke, Tessa Vanmaele, André Mouraux, Alexandre Stouffs, José Biurrun Manresa & Diana Torta
Animal studies have shown that high-frequency stimulation (HFS) of peripheral C-fibers induces long-term potentiation (LTP) within spinal nociceptive pathways. The aim of this replication study was to assess if a perceptual correlate of LTP can be observed in humans. In 20 healthy volunteers we applied HFS to the left or right volar forearm. Before and after applying HFS we delivered single electrical test stimuli through the HFS electrode while a second electrode at the contralateral...

Tragedy of the commons in Melipona bees revisited

Ricardo Caliari Oliveira, Viviana Di Pietro, José Javier G. Quezada-Euán, Jorge Ramirez Pech, Humberto Moo-Valle & Tom Wenseleers
Melipona stingless bees display a paradoxical overproduction of queens, which are later eliminated by nestmate workers. Mechanistically, it was suggested that the monoterpenoid geraniol deposited into newly provisioned cells by adult bees would cause larvae to develop into queens in Melipona beecheii. This system could be evolutionarily stable if many of these new queens would leave the nest and parasitize other genetically unrelated colonies nearby, as was shown to occur in a congeneric species. Here,...

The photosensitive phase acts as a sensitive window for seasonal multisensory neuroplasticity in male and female starlings

Jasmien Orije, Emilie Cardon, Julie Hamaide, Elisabeth Jonckers, Veerle Darras, Marleen Verhoye & Annemie Van Der Linden
Traditionally, research unraveling seasonal neuroplasticity in songbirds has focused on the male song control system and testosterone. We longitudinally monitored the song and neuroplasticity in male and female starlings during multiple photoperiods using Diffusion Tensor and Fixel-Based techniques. These exploratory data-driven whole-brain methods resulted in a population-based tractogram uncovering microstructural sexual dimorphisms in the song control system and beyond. Male brains showed microstructural hemispheric asymmetries, whereas females had higher interhemispheric connectivity, which could not be...

Dataset: Long term fMRI adaptation depends on adapter response in face-selective cortex

Daphne Stam, Jan Van Den Stock, Yun-An Huang, Kristof Vansteelandt, Stefan Sunaert, Ron Peeters, Charlotte Sleurs, Leia Vrancken, Louise Emsell, Rufin Vogels & Mathieu Vandenbulcke
Repetition suppression (RS) reflects a neural attenuation during repeated stimulation. We used fMRI and the subsequent memory paradigm to test the predictive coding hypothesis for RS during visual memory processing by investigating the interaction between RS and differences due to memory in category-selective cortex (FFA, pSTS, PPA, and RSC). Fifty-six participants encoded face and house stimuli twice, followed by an immediate and delayed (48 h) recognition memory assessment. Linear Mixed Model analyses with repetition, subsequent...

Restricted X chromosome introgression and support for Haldane’s rule in hybridizing damselflies

Janne Swaegers
Contemporary hybrid zones act as natural laboratories for the investigation of species boundaries and allow to shed light on the little understood roles of sex chromosomes in species divergence. Sex chromosomes are considered to function as a hotspot of genetic divergence between species; indicated by less genomic introgression compared to autosomes during hybridisation. Moreover, they are thought to contribute to Haldane’s rule which states that hybrids of the heterogametic sex are more likely to be...

Data from: Evolution of cold tolerance and thermal plasticity in life history, behaviour and physiology during a poleward range expansion

José Antonio Carbonell, Ying-Jie Wang & Robby Stoks
1. Many species that are moving polewards encounter novel thermal regimes to which they have to adapt. Therefore, rapid evolution of thermal tolerance and of thermal plasticity in fitness-related traits in edge populations can be crucial for the success and speed of range expansions. 2. We tested for adaptation in cold tolerance and in life history, behavioural and physiological traits and their thermal plasticity during a poleward range expansion. 3. We reconstructed the thermal performance...

A trait-based approach across the native and invaded range to understand plant invasiveness and community impact

Kenny Helsen, Hajime Matsushima, Ben Somers & Olivier Honnay
Alien plant species invasiveness and impact on diversity (i.e. species richness and composition) can be driven by the altered competitive interactions experienced by the invader in its invaded range compared to its native range. Trait-based competition effects on invasiveness can be mediated through size-asymmetric competition, i.e. a trait suit of the invader that drives competitive dominance, and through ‘niche differences’, i.e. trait differentiation and thus minimized competition between invader and the invaded community. In terms...

Supplementary datasets from: The wettability of electron spun membranes by synovial fluid

Lukas Capek, Ales Hrouda, Radek Jirkovec, Petra Hamrikova, Maarten Vanierschot & Kathleen Denis
Aseptic loosening due to periprosthetic osteolysis has been accepted as one of the leading causes of revision procedures in patients with previous joint arthroplasty. Recently, several strategies for suppression of osteolysis were proposed, mostly based on biological treatment such as mitigation of chronic inflammatory reactions. However, these biological treatments do not stop the debris migration but only reduce the inflammatory reaction. To address this shortcoming, we propose the concept of ultrahigh molecular weighted polyethylene (UHMWPE)...

Physically asymmetric division of the C. elegans zygote ensures invariably successful embryogenesis

Radek Jankele, Pierre Gönczy & Rob Jelier
Asymmetric divisions that yield daughter cells of different sizes are frequent during early embryogenesis, but the importance of such a physical difference for successful development remains poorly understood. Here, we investigated this question using the first division of C. elegans embryos, which yields a large AB cell and a small P1 cell. We equalized AB and P1 sizes using acute genetic inactivation or optogenetic manipulation of the spindle positioning protein LIN-5. We uncovered that only...
