Impacts of Recurrent Estuarine Acidification on Wild Invertebrates (10 July 2012)
How debilitating are they? The results of this study suggest that “at the population level, calcifying organisms display a certain degree of natural resistance” to ocean acidification brought about by either natural behavior, long-term physiological acclimation, and/or genetic selection… Read More

Global Warming Fosters High-Latitude Cooling? (10 July 2012)
Whereas CO2-induced global warming has for decades been predicted to be amplified in Earth’s high latitudes, it is now being suggested (by some) that it cools those regions… Read More

The King Penguin Population on Macquarie Island (10 July 2012)
Populations of king penguins on Macquarie Island have not only rebounded but a recent study has revealed that genetic diversity is now as great as it was before 19th century overhunting… Read More

Atmospheric CO2 Enrichment: Working Wonders in the Plant Root Zone (11 July 2012)
At the end of a 12-day experiment, it was determined that the length of fungal extraradical mycelium had been significantly increased by some 90% by an approximate doubling of the atmospheric CO2 concentration… Read More

The Ability of Marine Turtles to Adapt to Warmer Environments (11 July 2012)
Offspring of female turtles nesting on a naturally hot (black sand) beach “survived better and grew larger at hot incubation temperatures” compared with the offspring of females nesting on a cooler (pale sand) beach, which findings “suggest that the increased heat-tolerance of [black sand beach] turtles has a genetic basis”… Read More

Global Warming: Does It Promote or Hinder Peace? (11 July 2012)
“Analysis at the system level suggests that global warming is associated with a reduction in interstate conflict,” and that “incorporating measures of development, democracy, cross-border trade, and international institutions reveals that systemic trends toward peace are actually best accounted for by the increase in average international income”… Read More

Soluble Exudates Produced by Ectomycorrhizal Roots of Scots Pine Trees (11 July 2012)
Johansson et al. report they observed “a clear impact of elevated CO2 on exudation of soluble low molecular weight organic compounds,” and that these exudates “increased by 120-270%” due to “the increased carbon availability to the plant-fungus system,” which was driven by the increased atmospheric CO2 concentration employed in their study, and which led to a mean increase of 27% in the growth (i.e., total biomass production) of the seedlings infected with the eight different species of ECM fungi, but which led to only a 14% increase in the biomass of the non-infected seedlings… Read More
