Food selection of a generalist herbivore exposed to native and alien seaweeds
2018
Understanding which factors influence the invasion of alien seaweed has become a central concern in ecology. Increasing evidence suggests that the feeding preferences of native herbivores influence the success of alien seaweeds in the new community. We investigated food selection of a generalist native grazer Paracentrotus lividus, in the presence of two alien seaweeds (Caulerpa cylindracea and Caulerpa taxifolia var. distichophylla) and two native seaweeds (Dictyopteris membranacea and Cystoseira compressa). Sea urchins were fed with six experimental food items: C. cylindracea, C. taxifolia var. distichophylla, a mixture of C. cylindracea and C. taxifolia var. distichophylla, D. membranace…

Preference for Identification in the Field – Nudging Refugees’ Integration Effort
2019
Social identity greatly affects behavior. However, less is known about individual’s investment into identification, i.e. into belonging to a social group. We design a field experiment that allows us to make effort as an investment into a new group identity salient. The social identity in our treatment is refugee’s identification with the host society. We modified a mailing to 5600 refugees who use an online language-learning platform to learn the host countries’ language. These treatment emails make salient that improving the host country’s language ability increases the belonging to the host society. Our analysis reveals that the treatment has a significant positive effect on the effort ex…
The Structure and Behavioural Effects of Revealed Social Identity Preferences
2020
A large body of evidence shows that social identity affects behaviour. However, our understanding of the substantial variation of these behavioural effects is still limited. We use a novel laboratory experiment to measure differences in preferences for social identities as a potential source of behavioural heterogeneity. Facing a trade-off between monetary payments and belonging to different groups, individuals are willing to forego significant earnings to avoid belonging to certain groups. We then show that individual differences in these foregone earnings correspond to the differences in discriminatory behaviour towards these groups. Our results illustrate the importance of considering in…
Subjective responses to different light sources. A study on light preferences and comparison of standard light measures with human individual estimat…
2013
The experimental research here described investigates how people perceive different light sources that have same CCTs and illuminance values on a visual task. The results show that photometric quantities like illuminances and CCTs fail to guarantee users comfort, because parameters like SPD of the light source and its technology heavily influence people's perception of an environment.
Lesions of the dopaminergic innervation of the nucleus accumbens medial shell delay the generation of preference for sucrose, but not of sexual phero…
2011
Male sexual pheromones are rewarding stimuli for female mice, able to induce conditioned place preference. To test whether processing these natural reinforcing stimuli depends on the dopaminergic innervation of the nucleus accumbens, as for other natural rewards, we compare the effects of specific lesions of the dopaminergic innervation of the medial shell of the nucleus accumbens on two different appetitive behaviours, ‘pheromone seeking’ and sucrose preferential intake. Female mice, with no previous experience with either adult male chemical stimuli or with sucrose, received injections of 6-hydroxydopamine (or vehicle) in the medial shell of the accumbens. Then, we analyzed their preferen…
Review paper: Ecological genetics of Brachionus sympatric sibling species
1998
In this paper we review previous studies on sympatric Brachionus populations in Torreblanca Marsh as a model of evolutionary and ecological relationships between closely related species. The marsh is a wetland on the Mediterranean coast of Spain with high spatial and temporal heterogeneity. Allozyme and morphometric analysis showed that Brachionus group plicatilis (formerly, Brachionus plicatilis and currently split into B. plicatilis and B. rotundiformis) was composed of three groups of genotypes with no evidence of gene flow between them (B. plicatilis, B. rotundiformis SM and B. rotundiformis SS). Correlations between seasonal and spatial distributions, on one hand, and temperature and s…
Children's acceptance of new foods at weaning. Role of practices of weaning and of food sensory properties
2011
International audience; Weaning (i.e. introduction of complementary foods) is a transitional process between the consumption of a unique food, milk, and family foods. This review of existing literature regarding factors favouring the development of food acceptance at the beginning of weaning underlines in particular the roles of repeated exposure, of introduction of a variety of foods, of timing of introduction of weaning foods, and of food sensory properties (texture, taste and flavours). All factors appear to play a role in the acceptance of weaning foods. The efficiency, most favourable windows and long-term impact of each of these factors is not known accurately.
