Bars on histograms indicate one standard deviation. Different letters in (A) indicate significant differences at the 5% level with Tukey's multiple comparison test. n.s. in (B) indicates no significant difference with ANOVA at the 5% level.

Data from: Acute embryonic anoxia exposure favours the development of a dominant and aggressive phenotype in adult zebrafish
Eutrophication and climate change are increasing the incidence of severe hypoxia in fish nursery habitats, yet the programming effects of hypoxia on stress responsiveness in later life are poorly understood. In this study, to investigate whether early hypoxia alters the developmental trajectory of the stress response, zebrafish embryos were exposed to 4 h of anoxia at 36 h post-fertilization and reared to adults when the responses to secondary stressors were assessed. While embryonic anoxia did not affect basal cortisol levels or the cortisol response to hypoxia in later life, it had a marked effect on the responses to a social stressor. In dyadic social interactions, adults derived from embryonic anoxia initiated more chases, bit more often, entered fewer freezes and had lower cortisol levels. Adults derived from embryonic anoxia also performed more bites towards their mirror image, had lower gonadal aromatase gene expression and had higher testosterone levels. We conclude that acute embryonic anoxia has long-lasting consequences for the hormonal and behavioural responses to social interactions in zebrafish. Specifically, we demonstrate that acute embryonic anoxia favours the development of a dominant and aggressive phenotype, and that a disruption in sex steroid production may contribute to the programming effects of environmental hypoxia.

Figure 5 - A schematic representation showing the ultrastructural characteristics of the hindgut apical matrices and epithelium during late intramarsupial development and in comparison to the hindgut cuticular lining of adult animals in Porcellio scaber. The axis represents the successive developmental stages and the percentage of embryonic development. The vertical dashed lines indicate the transition from embryonic to larval development and from larval development to adult stage. The thick horizontal lines represent presence of the individual feature in the certain stages. The specific features of the cuticle are indicated by the thin lines.

The matrix consists of an electron dense lamina (black →) and underlying more electron lucent homogenous material. The apical membrane displays irregularly arranged protrusions (white →) B, C, D In the stage 18 embryos the apical matrix of the hindgut (AM) is extensive. The surface lamina covers the matrix, which displays a distal region of medium density and a proximal lucent region. The lamina of this matrix is trilayered (B inset). A new electron dense lamina (B, D - black →) is evident above the apical membrane protrusions (B, D - white →). The new lamina is mostly continuous, though in some regions it still appears in fragments (C - black →) E, F In the prehatching embryo of stage 19 the hindgut apical matrix consists of a distal trilayered lamina (black →), an electron dense material, accumulating underneath the lamina (F - white →) and underlying lucent material (E - *). Microvilli-like protrusions of the apical plasma membrane are evident (E - white →). The gut lumen is filled with homogenous material.
