ecosystem

An ecosystem is a community of living organisms (plants, animals and microbes) in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system.[2] These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows.[3] As ecosystems are defined by the network of interactions among organisms, and between organisms and their environment,[4] they can come in any size but usually encompass specific, limited spaces[5] (although some scientists say that the entire planet is an ecosystem).[6]

Avoiding a crisis The new numbers are just estimates, but they are much lower than previous studies, which put the number of [...]

Earth took 10 million years to recover from biggest extinction

Some 250 million years ago, life on Earth passed through its toughest time so far, as 96% of all marine species and over three quarters of land vertebrates went extinct. According to British researchers, the mass extinction was so severe that it took life 10 million years to recover. With less than 10 percent of [...]

Seagrass on ocean coasts can store twice as much carbon as tropical rainforests, yet face destruction

A new research from a team of international marine geoscientists has found that seagrass meadows, found in coastal regions, can store up to twice as much carbon as temperate or tropical forests. The scientists involved in the study, thus, believe that seagrasses can potentially become a viable solution to climate change, if scaled and preserved [...]

Climate change and over-fishing are held responsible for the swift collapse of coral reefs and the propagation of mass extinction among marine life. According to the International Programme on the State of the Ocean (IPSO), which presented the study this Tuesday to the U.N., the Earth is faced with its biggest spate of mass extinctions [...]

Fool’s gold is ocean’s fertilizer

Bacteria and small plants at the bottom of the ocean require significant quantities of iron to survive and grow, just like us humans do. But their situation is extremely different, and they can’t just opt for an iron rich diet. So where does their iron come from ?   Pyrite, or fool’s gold (as it [...]

Boy I’ve gotta tell you, my jaw really dropped when I heard this one. There are actual lakes, on the bottom of oceans, especially in the Gulf of Mexico region; they’ve got their own shores and all. The brine water of these lakes actually hosts unique wildlife, creating an absolutely amazing environment. The fact that [...]

The British Antarctic Survey (BAS) published some quite awesome pictures showing that Antarctica isn’t the lifeless frozen wasteland most people believe it to be; ice fish, octopus, sea pigs, giant sea spiders, rare rays and gorgeous basket stars all thrive in the extreme temperatures in Antarctica’s waters. Well, thrive is perhaps a too strong word, [...]
