THESE ARE PRIMITIVE WORLDS?

— the research teased out these details by using 21,946 fossil specimens from areas of nevada in the us and the yukon in canada that were once ancient sea beds to paint a picture of graptolite evolution.  52 more words

Response of marine copepods to a changing tropical environment: winners, losers and implications

Background. Climate change concurrent with anthropogenic disturbances can initiate serial changes that reverberate up the food chain with repercussions for fisheries. To date, there is no information available concerning the combined effects of global warming and human impacts on tropical marine food webs. 357 more words

Your Definition of Plankton

Plankton – the little floaty things in the ocean that whales eat, right? So much more. For example: chalk. 986 more words

Ocean acidification effects on the nutritional quality of phytoplankton for copepod reproduction

Four species of phytoplankton (Rhodomonas salina, Skeletonema marinoi, Prorocentrum micans, Isochrysis galbana) were grown under present-day low (400ppm pCO2, pH~8.1) and predicted-future high (lOOOppm pCO2, pH~7.8) ocean acidification conditions using nitrate-limited semi-continuous batch cultures. 138 more words

Insidious Danger: Microplastics Pollute Aquatic Life and Harm Our Food Supply

By Roberta Attanasio, IEAM Blog Editor

Microplastics—the tiny bits of plastic that are now infamously and ubiquitously present in the world’s waterways—are polluting aquatic life and ending up in our food supply. 766 more words

Ocean acidification reduces transfer of essential biomolecules in a natural plankton community

Ocean acidification (OA), a process of increasing seawater acidity caused by the uptake of anthropogenic carbon dioxide (CO2) by the ocean, is expected to change surface ocean pH to levels unprecedented for millions of years, affecting marine food web structures and trophic interactions. 175 more words

Response of antioxidant defense system in copepod Calanus sinicus Brodsky exposed to CO2-acidified seawater

Marine zooplankton responds sensitively to elevated seawater CO2 concentration. However, the underlying physiological mechanisms have not been studied well. We therefore investigated the effects of elevated CO2 concentration (0.08%, 0.20%, 0.50% and 1.00%) on antioxidant defense components, as well as two detoxification enzymes of Calanus sinicus (copepod). 148 more words
