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...

The hornwort genome and early land plant evolution

Jian Zhang, Xin-Xing Fu, Rui-Qi Li, Xiang Zhao, Yang Liu, Ming-He Li, Arthur Zwaenepoel, Hong Ma, Bernard Goffinet, Yan-Long Guan, Jia-Yu Xue, Yi-Ying Liao, Qing-Feng Wang, Qing-Hua Wang, Jie-Yu Wang, Guo-Qiang Zhang, Zhi-Wen Wang, Yu Jia, Mei-Zhi Wang, Shan-Shan Dong, Jian-Fen Yang, Yuan-Nian Jiao, Ya-Long Guo, Hong-Zhi Kong, An-Ming Lu … & Zhi-Duan Chen
Hornworts, liverworts, and mosses are three early diverging clades of land plants, together composing the bryophytes. Here we report the draft genome sequence of the hornwort Anthoceros angustus. Phylogenomic inferences confirm the monophyly of bryophytes, with hornworts sister to liverworts and mosses. The simple morphology of hornworts correlates with low genetic redundancy in plant body plan while the basic transcriptional regulation toolkit for plant development has already been established in this early land plant lineage....

Signal evolution and morphological complexity in hummingbirds (Aves: Trochilidae)

Chad Eliason, Rafael Maia, Juan Parra & Matthew Shawkey
Understanding how animal signals are produced is critical for understanding their evolution because complexity and modularity in the underlying morphology can affect evolutionary patterns. Hummingbird feathers show some of the brightest and most iridescent colors in nature. These are produced by optically complex stacks of hollow, platelet-shaped organelles called melanosomes. Neither how these morphologies produce colors nor their evolution has been systematically studied. We first used nanoscale morphological measurements and optical modeling to identify the...

A preliminary field trial to compare control techniques for invasive Berberis aquifolium in Belgian coastal dunes

Tim Adriaens, Pieter Verschelde, Emma Cartuyvels, Bram D'hondt, Edward Vercruysse, Wouter Van Gompel, Evy Dewulf & Sam Provoost
Non-native Berberis aquifolium is notoriously invasive in Belgian coastal dunes. With its strong clonal growth through suckers, this evergreen shrub outcompetes native species and affects dune succession. To prevent further secondary spread and mitigate its impact, there was an urgent need for knowledge on the effectiveness of control measures, both at the plant and habitat level. Here, we report on a first control experiment. Individual B. aquifolium clones were subjected to one of four treatments...

Data from: Induced phenological avoidance: a neglected defense mechanism against seed predation in plants

Bram Sercu, Iris Moeneclaey, Dries Bonte & Lander Baeten
1. Flowering phenology is an important life history trait affecting plant reproductive performance and is influenced by various abiotic and biotic factors. Pre-dispersal seed predation and pollination are expected to impose counteracting selection pressure on flowering phenology, with pre-dispersal seed predation expected to favor off-peak flowering and pollination to favor synchronous flowering. 2. Here we studied the effect of pre-dispersal seed predation by the beetle Byturus ochraceus, a specialist seed herbivore, on the flowering phenology...

Let's talk about pain catastrophizing measures: an item content analysis

Geert Crombez, Annick De Paepe, Elke Veirman & Dimitri Van ryckeghem
Concerns have been raised about whether self-report measures of pain catastrophizing actually reflect the construct as defined in the cognitive-behavioral literature. In this project, we investigated the content validity of self-report measures of pain catastrophizing.

Because You Had a Bad Day: General and Daily Relations between Reactive Temperament, Emotion Regulation, and Depressive Symptoms in Youth

Marie-Lotte Van Beveren, Sofie Kuppens, Benjamin Hankin & Caroline Braet
Negative emotionality (NE) and positive emotionality (PE) have repeatedly shown to act as vulnerability factors for youth depression. Less research examined the mechanisms through which these reactive temperament traits may differently confer vulnerability to depression. Based on recent integrated models of depression proposing emotion regulation as a key underlying mechanism, the current study aimed to clarify the general and day-to-day relations among temperament, emotion regulation strategies, and depressive symptoms in Dutch-speaking youth (35% boys; M_age...

Data from: Stressor fluxes alter the relationship between beta-diversity and regional productivity

Jonathan De Raedt, Jan M. Baert, Colin R. Janssen & Frederik De Laender
Dispersal of organisms can influence the relationship between beta-diversity and regional productivity in heterogeneous environments. However, many ecosystems are also linked by fluxes of stressors, with an unknown influence on this relationship. In this study, we assess the relationship between beta-diversity (measured as Bray-Curtis dissimilarity) and regional productivity (measured as biovolume) under various levels of a stressor flux in meta-ecosystems that were composed of two marine micro-algae communities. We created heterogeneity by exposing one of...

Data from: Long-term recovery of the functional community assembly and carbon pools in an African tropical forest succession

Marijn Bauters, Oscar Vercleyen, Bernard Vanlauwe, Johan Six, Bernard Bonyoma, Henri Badjoko, Wannes Hubau, Alison Hoyt, Mathieu Boudin, Hans Verbeeck & Pascal Boeckx.
On the African continent, the population is expected to expand fourfold in the next century, which will increasingly impact the global carbon cycle and biodiversity conservation. Therefore, it is of vital importance to understand how carbon stocks and community assembly recover after slash-and-burn events in tropical second-growth forests. We inventoried a chronosequence of 15 1-hectare plots in lowland tropical forest of the central Congo Basin and evaluated changes in aboveground and soil organic carbon stocks...

Data from: Sharing the burden: on the division of parental care and vocalizations during incubation

Marwa M. Kavelaars, Luc Lens & Wendt Müller
In species with biparental care, individuals only have to pay the costs for their own parental investment, while the contribution of their partner comes for free. Each parent hence benefits if its partner works harder, creating an evolutionary conflict of interest. How parents resolve this conflict and how they achieve the optimal division of parental tasks often remains elusive. In this study, we investigated whether lesser black-backed gulls (Larus fuscus) divide parental care during incubation...

Optimal foraging explains novel movement behavior of benthic diatoms

Wen-Si Hu, Ming-Ji Huang, H.P. Zhang, Feng Zhang, Wim Vyverman & Quan-Xing Liu
Adaptive locomotion of living organisms contributes to their competitive abilities and helps maintain their fitness in diverse environments. To date, however, our understanding of searching behavior and its ultimate cause remains poorly understood in ecology and biology. Here, we investigate motion patterns of biofilm-inhabiting marine raphid diatom Navicula arenaria var. rostellata in two-dimensional space. We report that individual Navicula cells display a “circular-run-and-reversal” movement behavior at different concentrations of dissolved silicic acid (dSi). We show...

Data from: High ecosystem service delivery potential of small woodlands in agricultural landscapes

Alicia Valdés, Jonathan Lenoir, Pieter De Frenne, Emilie Andrieu, Jorg Brunet, Olivier Chabrerie, Sara Cousins, Marc Deconchat, Pallieter De Smedt, Martin Diekmann, Steffen Ehrmann, Emilie Gallet-Moron, Stefanie Gaertner, Brice Giffard, Karin Hansen, Martin Hermy, Annette Kolb, Vincent Leroux, Jaan Liira, Jessica Lindgren, Ludmilla Martin, Tobias Naaf, Taavi Paal, Willem Proesmans, Michael Scherer-Lorenzen … & Guillaume Decocq
Global forest loss and fragmentation have strongly increased the frequency of forest patches smaller than a few hectares. Little is known about the biodiversity and ecosystem service supply potential of such small woodlands in comparison to larger forests. As it is widely recognized that high biodiversity levels increase ecosystem functionality and the delivery of multiple ecosystem services, small, isolated woodlands are expected to have a lower potential for ecosystem service delivery than large forests hosting...

Mechanisms for color convergence in a mimetic radiation of poison frogs

Evan Twomey, Morgan Kain, Myriam Claeys, Kyle Summers, Santiago Castroviejo-Fisher & Ines Van Bocxlaer
In animals, bright colors often evolve to mimic other species when a resemblance is selectively favored. Understanding the proximate mechanisms underlying such color mimicry can give insights into how mimicry evolves, for example, whether color convergence evolves from a shared set of mechanisms or through the evolution of novel color production mechanisms. We studied color production mechanisms in poison frogs (Dendrobatidae), focusing on the mimicry complex of Ranitomeya imitator. Using reflectance spectrometry, skin pigment analysis,...
