Two ecologist discover that by adapting Google’s Page Rank algorithm they were able to “reverse engineer” the collapse of food webs, and thus determining which species in a given web are most critical to the web’s existence.
The ‘bearded goby’ (Sufflogobius bibarbatus), a small, common, prey species of fish, has become adapted to the “toxic” conditions near the sea floor of this pelagic zone. Analysis of the fish’s gut has shown that up to 60% of its diet consists of jellyfish–a marine creature few animals prey upon due to their venomous stings. Remarkably, the fish has become the pivotal player in a newly emergent ecosystem.
Phytoplankton–tiny, marine plants that formthe basis of our oceans’ food chain–absorb and sequester large amounts of CO2 from the atmosphere and generate half of the world’s oxygen supply. Given such an important ecosystem service as this, one would hope that our oceans’ algae numbers stay high…but, the results of a three year data analysis are anything but encouraging.
