Secrets of fish population changes revealed

Fri, 08 Jun 2018 10:19:32 EDT ~ Populations of fish in the ocean are notoriously variable, waxing and waning in often unpredictable ways. Knowing what drives changes in fish population sizes is important for managing fisheries and conserving species. For the first time, scientists have linked the ecology of adult fish populations inhabiting coral reefs with the dispersal of baby fish between reefs, reporting the dynamics of a living network called a 'marine metapopulation.'

Algal partner responds to climate-change stresses more strongly than coral host

Thu, 07 Jun 2018 11:26:57 EDT ~ A new study puts a surprising twist into our understanding of how coral reefs react to ocean warming and acidification and may offer an early warning system for warmth-induced coral bleaching events. Find out more...

Nutrient pollution makes ocean acidification worse for coral reefs

Wed, 06 Jun 2018 09:37:36 EDT ~ A new study showed that local impacts of humans -- nutrient pollution from activities on land -- may accelerate the negative impacts of global ocean acidification on coral reefs. Find out more...

Invasive species of coral boasts amazing capacity for regeneration

Tue, 05 Jun 2018 17:25:03 EDT ~ Colonies of sun coral multiply rapidly, driving native corals out. Scientists investigate whether the rising of oceanic temperature, combined with increasing activity of the oil and gas industry, might be favoring the invasive species. Find out more...

Study in Fiji finds that removing sea cucumbers spells trouble for shallow coastal waters

Tue, 05 Jun 2018 17:25:00 EDT ~ The sea cucumber's unimpressive appearance belies the outsized role these creatures play in converting decomposing organic matter into recyclable nutrients and keeping coastal ecosystems healthy and clean, and overfishing them can have negative impacts on coastal marine environments, according to a new study focusing on a species of sea cucumber called a sandfish.

New invention safely transports unknown, deep-dwelling fishes to the ocean's surface

Mon, 04 Jun 2018 11:25:38 EDT ~ Strange and beautiful fishes from the ocean's deep and lesser-known twilight zone reefs are hitching a ride to the surface thanks to the newly invented SubCAS (or Submersible Chamber for Ascending Specimens). This ingenious pressurized chamber stretches two feet long and is used by scientific divers to collect and safely surface charismatic reef residents for further study and public display.

Rise and fall of the Great Barrier Reef

Mon, 28 May 2018 12:40:08 EDT ~ Study is first of its kind to reconstruct evolution of reef over 30,000 years in response to abrupt environmental change. Find out more...

Shedding light on immune response in diseased corals

Thu, 24 May 2018 17:45:53 EDT ~ Researchers have found a correlation between a strong immune response in diseased corals and a lower expression of genes associated with growth and reproduction. Find out more...

Opportunity to restore abundance to Hawaiian reef fisheries

Thu, 24 May 2018 14:16:39 EDT ~ A new study has identified areas in the Hawaiian Islands that would provide the greatest increase in coastal fishery stocks, if effectively managed. Find out more...

Excess nutrients, coupled with climate change, damage the most highly resilient corals

Wed, 23 May 2018 13:32:36 EDT ~ Experimentalists conducted a simulation of future conditions in the Red Sea caused by global warming and acidification, while simultaneously increasing levels of nutrients such as nitrate and phosphate. They found that when nitrate and phosphate were added, the coral thermal resilience was compromised while algal growth benefited from excess CO2 and nutrients. Algal dominance over corals in the reef means losing all of the beauty and biodiversity of the coral reefs. Find out more...
