Floral nectar is a chemically complex aqueous solution within which several secondary metabolites have been identified that affect attractiveness for pollinators. Understanding preferences and aversions to quality in flower visitors crucial since this may influence the patterns of insect floral visitation with consequences on plant fitness. We hypothesise chemical variation through different se...

This paper explores whether firms recruit workers with different personality traits for tasks. We conduct a discrete choice experiment among recruiters of 634 in Germany, asking to choose between job applicants who differ seven characteristics: professional competence, the Big Five traits, and prospective wage level. find that all affect hiring probability applicant, conscientiousness agreeable...

Behavioural ecologists increasingly recognise spatial memory as one the most influential cognitive traits involved in evolutionary processes. In particular, spatial working memory (SWM), i.e. the ability of animals to store temporarily useful information for current foraging tasks, determines the foraging efficiency of individuals. As a consequence, SWM also has the potential to influence compe...

The link between callous-unemotional (CU) traits in youth and delinquent, aggressive and violent behavior is well-replicated in the literature. However, the mediating effects of violence exposure on this relationship are unclear. The current study addresses this important gap in the literature with a sample of 88 detained, primarily ethnic minority adolescent boys (M age = 15.57; SD = 1.28). Re...

knowledge about genetic diversity is an essential step towards conservation of genetic resources and developing further strategies for plant improvement. the objective of this research was to evaluate the agronomical and morphological traits and determine the level of variation within wild barley ecotypes especially for acclimation traits. in this study 188 ecotypes of wild barley (hordeumspont...
