INTERACTING ECOSYSTEMS. Robert MacArthur (1955) "argued that “Biodiversity begets stability”: when a species is part of a species-rich community, it will be better able to withstand environmental change and disturbance because of buffering effects through the complex network of biological interactions with other species in the community." http://link.springer.com/article/10.1007/s12080-016-0292-1 View in LinkedIn

THE DIVERSITY QUESTION. “Why are there so many species on earth?” Almost everywhere, we see many species living together. One answer of course is “niche differentiation” powerfully counteracting the Darwinian concept of competitive exclusion and the survival of the fittest." https://lnkd.in/dcnXnAQ View in LinkedIn

THE ENTANGLED BANK. "Although Darwin’s (1859) classic ‘entangled bank’ of species ‘dependent on each other in so complex a manner’ is often referred to in food web research, Darwin was referring to a wide variety of interactions in addition to feeding, e.g. bees pollinating flowers, shrubs providing shelter for other species and trees providing nesting habitat for birds." http://onlinelibrary.wiley.com/doi/10.1111/j.1461-0248.2011.01732.x/full View in LinkedIn

BY NOSES, VIRUSES: TEN TO ONE. "The ocean contains many mysteries, but none so great as its viruses. Scientists estimate that there are 1,000,000,000,000,000,000,000,000,000,000 virus particles in all the world’s seas. They outnumber all cellular life forms by roughly a factor of 10." But, confoundingly, viruses are neither autotrophs nor heterotrophs. They do not "troph", only reproduce. https://lnkd.in/dKbvY75 View in LinkedIn

BY NOSES, BACTERIA: 4-6 x 10(30) cells. "The total amount of prokaryotic carbon is 60–100% of the estimated total carbon in plants, and inclusion of prokaryotic carbon in global models will almost double estimates of the amount of carbon stored in living organisms." Can be either heterotrophs or autotrophs. https://lnkd.in/dU7VJwv View in LinkedIn

2ND WHOPPING IGNORED CATEGORY. "Microbial and metazoan food webs are one. Believe it or not, this integrated approach is rare. Prokaryotic global biomass is at least 60% that of plants. Perhaps much more." And we only know a few percent of the species of bacteria, viruses and fungi. https://lnkd.in/dFC_Kpj View in LinkedIn
