Hypoxia likely compromises the reproductive success of those marine organisms carrying out external fertilization because their gametes and embryos are inevitably exposed to the external environment. Hydroides elegans, a dominant serpulid polychaete in Hong Kong waters, can spawn throughout the year but the number of recruits drops during summer when hypoxia commonly occurs. This study attempted to explain such observation by investigating the gamete quality, including sperm motility, egg size… Expand
Sperm motility and fertilisation success in an acidified and hypoxic environment
There was a significant negative effect of elevated pCO2 on fertilisation success, and when combined with a simulated hypoxic event there was an even greater effect. Expand
Sperm pHertility : male gamete responses to ocean acidification and other stressors
It is found that the length of time between spawning and fertilisation can strongly influence the impact of OA on sperm performance, and sperm are vulnerable to the projected changes in seawater carbonate chemistry under OA. Expand
Effects of environmental stressors affecting blue mussels Mytilus edulis Linnaeus, 1758 populations on the Sussex coast (UK)
Mussels from all three intertidal sites showed clear signs of stress, with reduced gamete survival being of extreme concern, and slight variations of environmental variables such as oxygen and salinity clearly influence the physiological responses in mussels. Expand
Effects of current and future coastal upwelling conditions on the fertilization success of the red abalone (Haliotis rufescens): Towards a Broader Perspective on Ocean Acidification Research Part 2 A special issue of the ICES Journal of Marine Science
&NA; Acidification, deoxygenation, and warming are escalating changes in coastal waters throughout the world ocean, with potentially severe consequences for marine life and ocean‐based economies. ToExpand


Hatching and viability of copepod eggs at two stages of embryological development: anoxic/hypoxic effect
Fully developed eggs from Acartia tonsa and Labidocera aestiva collected between July and September 1991 at Turkey Point, Florida, USA, hatched at lower oxygen concentrations than newly spawned eggs given the same incubation periods, indicating that newly spawn eggs were more sensitive to low oxygen concentrations. Expand
Physiological and behavioural responses of different life stages of a serpulid polychaete to hypoxia
This study strengthened the notion that low salinity contributes to adult mortality in summer; however, the lack of summer recruitment is possibly a result of the combined effect of low Salinity and hypoxia. Expand
Variation in sperm swimming behaviour and its effect on fertilization success in the serpulid polychaete Galeolaria caespitosa
Cross-fertilization experiments indicated that individual egg fertilizability and male-female compatibility also play an important role in determining the fertilization success and thus may obscure any effects of sperm motility. Expand
Aquatic hypoxia is a teratogen and affects fish embryonic development.
The results imply that hypoxia may have a teratogenic effect on fish and delay fish embryonic development, which may subsequently impair species fitness leading to natural population decline. Expand
Sperm quality influences male fertilization success in walleye (Sander vitreus)
It was found that both the number of sperm and sperm swimming speed were significantly related to fertilization success and this return diminished as the percentage of ova fertilized increased above 50%. Expand
Extreme anoxia tolerance in embryos of the annual killifish Austrofundulus limnaeus: insights from a metabolomics analysis
It appears that the suite of characters associated with normal development and entry into diapause II in this species prepares the embryos for long-term survival in anoxia even while the embryos are exposed to aerobic conditions. Expand
Impairment of sea urchin sperm quality by UV-B radiation: predicting fertilization success from sperm motility.
Impairment of sperm motility of sea urchin, as measured by the CASA method, can be used to predict reproductive success and ecological effects. Expand
Aquatic Hypoxia Is an Endocrine Disruptor and Impairs Fish Reproduction
Serum levels of testosterone, estradiol, and triiodothyronine significantly decreased in carp (Cyprinus carpio) upon chronic exposure to Hypoxia, indicating that adverse effects of hypoxia on reproductive performance resulted from endocrine disruption. Expand
Combined effects of salinity and temperature on juvenile survival, growth and maturation in the polychaete Hydroides elegans
The results support the ideas that early developmental stages are more sensitive to environmental stress than late juveniles and adults, and that juveniles are most vulnerable at the onset of benthic life. Expand
Stimulation of Metamorphosis in the Polychaete Hydroides elegans Haswell (Serpulidae).
The exact mechanisms by which Cs+ and excess K+ induce metamorphosis are still unclear, although it is assumed that these agents act by depolarizing the membranes of excitable sensory cells and not by interacting with specific receptors. Expand
