A new paper examines the rarely explored coral reefs in deep water, where less than 1% of light from the surface makes it through. The research identifies how these corals are able to survive in such a dark place.
What factors govern algae's success as 'tenants' of their coral hosts both under optimal conditions and when oceanic temperatures rise?
According to ecotoxicologist from Far Eastern Federal University (FEFU), from the 90s and during 2000s in the tissues of Russian Far Eastern mussels the concentration of organochlorine pesticides (OCPs) that had been globally used in agriculture in the mid-twentieth century has increased about ten times. OCPs pollute and affect badly the ecosystems of the Sea of Japan, the Sea of Okhotsk, and the Bering Sea. A related review was published in Water Research.
A newly identified genus and species of worm-like, freshwater clam, commonly known as a shipworm, eats rock and expels sand as scat while it burrows like an ecosystem engineer in the Abatan River in the Philippines.
Dominant, non-native plants reduce wetland biodiversity and abundance more than native plants do, researchers report. Even native plants that dominate wetland landscapes play better with others, the team found.
In nutrient-poor deep-sea sediments, microbes belonging to the Archaea have outcompeted bacterial microorganisms for millions of years. Their ability to efficiently scavenge dead cells makes them the basal producers in the food chain.
When plants absorb excess light energy during photosynthesis, reactive oxygen species are produced, potentially causing oxidative stress that damages important structures. Plants can suppress the production of reactive oxygen species by oxidizing P700 (the reaction center chlorophyll in photosystem I). A new study has revealed more about this vital process.
A team of international experts including La Trobe University ecologist Nick Bond, led by the University of Canterbury, are calling for urgent global change to how we manage and model river ecosystems.
A new study from UC San Francisco suggests that a protein found in the common bullfrog may one day be used to detect and neutralize a poisonous compound produced by red tides and other harmful algal blooms. The discovery comes as these waterborne toxic events are becoming increasingly common, a consequence of climate change making the world's oceans more hospitable to the microbes responsible for these formerly infrequent flare-ups.
A world-first study at James Cook University in Australia has found an alternative to antibiotics for treating bacterial infections in green sea turtles.
