During coral mass spawning events, which are in sync with the moon's cycle, stony coral colonies simultaneously release an underwater cloud of sperm and eggs for fertilization. But how do the sperm an...
One of the most colourful and captivating events on the coral reef’s calendar has been captured on video at Heron Island Research Station.
Mass coral spawning: A natural large-scale nutrient addition experiment
Mass coral spawning A natural large-scale nutrient addition experiment

A mass coral spawning event on the Heron Island reef flat in 2005 provided a unique opportunity to examine the response of a coral reef ecosystem to a large episodic nutrient addition. A post-major sp...
Spawning events in small and large populations of the green sea urchin Strongylocentrotus droebachiensis as recorded using fertilization assays
Spawning events in small large populations of the green sea urchin Strongylocentrotus droebachiensis recorded using fertilization assays
2014/5/4
During the winter and spring of 2002 and 2003, we used time-integrated fertilization assays to monitor sperm availability in three populations of the green sea urchin Strongylocentrotus droebachiensis...
Responses in dissolved nutrients and epilithon abundance to spawning salmon in Southeast Alaska streams
dissolved nutrients epilithon abundance spawning salmon Southeast Alaska streams
2014/5/8
Spawning Pacific salmon (Oncorhynchus spp.) historically transported massive quantities of marine-derived nutrients (MDN) into nutrient-poor streams of the Pacific Northwest. In southeast Alaska, we m...
Salmon-derived mercury and nutrients in a Lake Ontario spawning stream
Salmon-derived mercury nutrients Lake Ontario spawning stream
2014/5/19
We tested the hypothesis that concentrations of mercury species (Hg) and nutrients (NH4+, NO3-, P, and dissolved organic carbon) in abiotic and biotic components would be altered by the decomposition ...
Synchronisation in the molting and spawning activity of northern krill (Meganyctiphanes norvegica) and its effect on recruitment
molting and spawning northern krill
2014/5/21
The molting, spawning, and recruitment of northern krill (Meganyctiphanes norvegica) were analyzed over an annual cycle (1999-2000) in the Clyde Sea (west coast of Scotland). Results supported the hyp...
Sea urchin spawning in benthic boundary layers: Are eggs fertilized before advecting away from females?
Sea urchin spawning benthic boundary layers eggs fertilized before advecting females
2014/5/20
Past work on fertilization in echinoids and other egg-broadcasting, free-spawning invertebrates suggests that these organisms might be extremely sperm limited in the field unless individuals spawn in ...
