Journal ArticleDOI

TL;DR: Most plasticizers appear to act by interfering with the functioning of various hormone systems, but some phthalates have wider pathways of disruption, and given the sensitivity of some invertebrates, effects assessments are warranted in other invertebrate phyla.
Journal ArticleDOI
Concepts in sperm heterogeneity, sperm selection and sperm competition as biological foundations for laboratory tests of semen quality.
TL;DR: Despite many years of research, sperm quality assessment methods continue to provide imprecise data about fertility; here it is suggested that this may be a consequence of using tests that focus on the spermatozoa that would normally be unable to fertilise under natural conditions.
Journal ArticleDOI
Physiological and health consequences of social status in zebrafish (Danio rerio).
TL;DR: The wide-ranging physiological differences seen between dominant and subordinate zebrafish as a consequence of their social status suggest negative health impacts for subordinates after prolonged durations in those hierarchies.
Journal ArticleDOI
Atlantic salmon eggs favour sperm in competition that have similar major histocompatibility alleles
Sarah E. Yeates,Sigurd Einum,Ian A. Fleming,Hendrik-Jan Megens,René J. M. Stet,Kjetil Hindar,William V. Holt,Katrien J. W. Van Look,Matthew J. G. Gage +8 more
TL;DR: Contrary to the findings demonstrating mechanisms that promote MH complex heterozygosity, the results showed that males won significantly greater relative fertilization success when competing for eggs from genetically similar females at the MH class I.
Journal ArticleDOI
Gonadal transcriptome responses and physiological consequences of exposure to oestrogen in breeding zebrafish (Danio rerio)
Eduarda M. Santos,Gregory C. Paull,Katrien J. W. Van Look,Victoria Louise Workman,William V. Holt,Ronny van Aerle,Peter Kille,Charles R. Tyler +7 more
TL;DR: It was demonstrated that EE(2) exposure compromised the reproductive health of breeding zebrafish at environmentally relevant concentrations and the molecular mechanisms mediating some of these effects were identified and included those impacting processes central to gametogenesis in both males and females.
