Data from: Effects of immune challenge on the oviposition strategy of a noctuid moth

Heike Staudacher, Steph B. J. Menken & Astrid T. Groot
Infections can have detrimental effects on the fitness of an animal. Reproducing females may therefore be sensitive to cues of infection and be able to adaptively change their oviposition strategy in the face of infection. As one possibility, females could make a terminal investment and shift reproductive effort from future to current reproduction as life expectancy decreases. We hypothesized that females of the noctuid moth Heliothis virescens make a terminal investment and adapt their oviposition...

Data from: Adaptation of a polyphagous herbivore to a novel host plant extensively shapes the transcriptome of herbivore and host

Nicky Wybouw, Vladimir Zhurov, Catherine Martel, Kristie A. Bruinsma, Frederik Hendrickx, Vojislava Grbić & Thomas Van Leeuwen
Generalist arthropod herbivores rapidly adapt to a broad range of host plants. However, the extent of transcriptional reprogramming in the herbivore and its hosts associated with adaptation remains poorly understood. Using the spider mite Tetranychus urticae and tomato as models with available genomic resources, we investigated the reciprocal genomewide transcriptional changes in both spider mite and tomato as a consequence of mite's adaptation to tomato. We transferred a genetically diverse mite population from bean to...

Data from: Life-history evolution in response to changes in metapopulation structure in an arthropod herbivore

Annelies De Roissart, Nicky Wybouw, David Renault, Thomas Van Leeuwen & Dries Bonte
The persistence and dynamics of populations largely depends on the way they are configured and integrated into space and the ensuing eco-evolutionary dynamics. We manipulated spatial and temporal variation in patch size in replicated experimental metapopulations of the herbivore mite Tetranychus urticae and followed evolutionary dynamics over approximately 30 generations. A significant divergence in life history traits, physiological endpoints and gene expression was recorded in the spatially and spatiotemporally variable metapopulation, but also a remarkable...

Data from: Oviposition preference of cabbage white butterflies in the framework of costs and benefits of interspecific herbivore associations

Kaori Shiojiri, Maurice Sabelis & Junji Takabayashi
When deciding where to oviposit, herbivorous insects consider: (i) the plant’s value as a food source, (ii) the risks of competing with con- and heterospecific herbivores, and (iii) the risks of parasitism and predation on the host plant. The presence of con- and/or heterospecific competitors would further affect the oviposition preference, because the preceding herbivores induce direct/indirect defences in plants against forthcoming herbivores, and thereby alter oviposition decisions. In previous studies, the abovementioned factors have...

Data from: Beyond predation: the zoophytophagous predator Macrolophus pygmaeus induces tomato resistance against spider mites

Maria L. Pappas, Anke Steppuhn, Daniel Geuss, Nikoleta Topalidou, Aliki Zografou, Maurice W. Sabelis & George D. Broufas
Many predatory insects that prey on herbivores also feed on the plant, but it is unknown whether plants affect the performance of herbivores by responding to this phytophagy with defence induction. We investigate whether the prior presence of the omnivorous predator Macrolophus pygmaeus (Rambur) on tomato plants affects plant resistance against two different herbivore species. Besides plant-mediated effects of M. pygmaeus on herbivore performance, we examined whether a plant defence trait that is known to...

Data from: Predicting optimal outcomes in cognitive therapy or interpersonal psychotherapy for depressed individuals using the Personalized Advantage Index approach

Introduction: Although psychotherapies for depression produce equivalent outcomes, individual patients respond differently to different therapies. Predictors of outcome have been identified in the context of randomized trials, but this information has not been used to predict which treatment works best for the depressed individual. In this paper, we aim to replicate a recently developed treatment selection method, using data from an RCT comparing the effects of cognitive therapy (CT) and interpersonal psychotherapy (IPT). Methods: 134...

Data from: Decisions reduce sensitivity to subsequent information

Zohar Z. Bronfman, Noam Brezis, Rani Moran, Konstantinos Tsetsos, Tobias Donner & Marius Usher
Behavioural studies over half a century indicate that making categorical choices alters beliefs about the state of the world. People seem biased to confirm previous choices, and to suppress contradicting information. These choice-dependent biases imply a fundamental bound of human rationality. However, it remains unclear whether these effects extend to lower level decisions, and only little is known about the computational mechanisms underlying them. Building on the framework of sequential-sampling models of decision-making, we developed...

Data from: Global biogeography and evolution of Cuvierina pteropods

Alice K. Burridge, Erica Goetze, Niels Raes, Jef Huisman & Katja T. C. A. Peijnenburg
Background: Shelled pteropods are planktonic gastropods that are potentially good indicators of the effects of ocean acidification. They also have high potential for the study of zooplankton evolution because they are metazoan plankton with a good fossil record. We investigated phenotypic and genetic variation in pteropods belonging to the genus Cuvierina in relation to their biogeographic distribution across the world’s oceans. We aimed to assess species boundaries and to reconstruct their evolutionary history. Results: We...

Data from: Context-dependent alarm signalling in an insect

Paulien J. A. De Bruijn, Martijn Egas, Maurice W. Sabelis & Astrid T. Groot
Animals often respond to danger by raising alarm to inform others. Alarm signals come in many different forms, such as visual or mechanical display, sound or odour. Some animals produce vocal alarm signals that vary with the level of danger. For chemical alarm signals, virtually nothing is known about such context-dependent signalling due to a general notion that alarm pheromones have fixed compositions. Here, we show that larvae of the Western Flower Thrips (Frankliniella occidentalis)...

Data from: Seven common mistakes in population genetics and how to avoid them

Patrick Meirmans & Patrick G. Meirmans
As the data resulting from modern genotyping tools are astoundingly complex, genotyping studies require great care in the sampling design, genotyping, data analysis and interpretation. Such care is necessary because, with data sets containing thousands of loci, small biases can easily become strongly significant patterns. Such biases may already be present in routine tasks that are present in almost every genotyping study. Here, I discuss seven common mistakes that can be frequently encountered in the...

Data from: Active prey mixing as an explanation for polyphagy in predatory arthropods: synergistic dietary effects on egg production despite a behavioural cost

Renata Vieira Marques, Renato Almeida Sarmento, Felipe Lemos, Marçal Pedro-Neto, Maurice W. Sabelis, Madelaine Venzon, Angelo Pallini & Arne Janssen
1.Mixing of prey that differ in nutrient content or toxic compounds (dietary mixing) may allow synovigenic predatory arthropods to balance their diet or dilute toxins of different prey items to maximize performance: dietary mixing may therefore explain the prevalence of polyphagy in this functional group. 2.Several predatory arthropods can redress nutritional imbalances in their diet by actively mixing different diets, based on experiments with artificial diets or with prey that were manipulated to contain different...
