Assessment of seminal oxidative stress indicators is emerging as a valuable prognostic tool in assisted reproductive
technology. We investigated levels of oxidative stress caused by reactive oxygen s...
Location Isn't Everything But Timing Is for Certain Spawning Fish
Location Isn't Everything Timing Certain Spawning Fish
2015/7/13
The larvae of some species of reef fish appear to survive better depending on the timing of when they were spawned, according to new research from the National Institute for Mathematical and Biologica...
One of the most colourful and captivating events on the coral reef’s calendar has been captured on video at Heron Island Research Station.

Critical Displacement Velocity Atlantic salmon
2009/5/18
This study focuses on understanding the temporal variability in hydrological and thermal conditions in a small mountain stream and its potential implication for two life stages of Atlantic salmon (Sal...
Mass coral spawning: A natural large-scale nutrient addition experiment
Mass coral spawning A natural large-scale nutrient addition experiment
2014/4/21
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...
Gonadal Maturation and Spawning in Penaeus semisulcatus de Hann, 1844 by Hormone Injection
Penaeus semisulcatus maturation spawning, hormone injection eggs
2010/3/29
The effects of 3 hormones, HCG, LH-RH and serotonin (5-HT), on maturation and spawning of Penaeus semisulcatus de Hann, 1844 were investigated in 2 experiments in this study. The experiments were carr...
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 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 ...
