title: Data from: Interactive effects of inbreeding and endocrine disruption on reproduction in a model laboratory fish

description: Inbreeding depression is expected to be more severe in stressful
 environments. However, the extent to which inbreeding affects the
 vulnerability of populations to environmental stressors, such as chemical
 exposure, remains unresolved. Here we report on the combined impacts of
 inbreeding and exposure to an endocrine disrupting chemical (the
 fungicide, clotrimazole) on zebrafish (Danio rerio). We show that whilst
 inbreeding can negatively affect reproductive traits, not all traits are
 affected equally. Inbreeding depression frequently only became apparent
 when fish were additionally stressed by chemical exposure. Embryo
 viability was significantly reduced in inbred exposed fish and there was a
 tendency for inbred males to sire fewer offspring when in direct
 competition with outbred individuals. Levels of plasma 11
 keto-testosterone, a key male sex hormone, showed substantial inbreeding
 depression that was unaffected by addition of the fungicide. In contrast,
 there was no effect of inbreeding or clotrimazole exposure on egg
 production. Overall, our data provide evidence that stress may amplify the
 effects of inbreeding on key reproductive traits, particularly those
 associated with male fitness. This may have important implications when
 considering the consequences of exposure to chemical pollutants on the
 fitness of wild populations.
description: Figure_3_ExperimentIData collected in the laboratory, for the number of eggs spawned per female, over the 10 day study period of Experiment I. Each spawning group (each tank) contained 1 female and 2 males (either all inbred fish or all outbred as indicated in table). Low dose refers to previous exposure to 5 ug/L clotrimazole (nominal) as detailed in manuscript.Figure_3_ExperimentIIData collected in the laboratory, for the number of eggs spawned per female, over the 10 day study period of Experiment II.
