Developmental Thermal Acclimation in a Species of Damselfish

Published August 22, 2013

Tropical ectotherms are predicted to “be especially sensitive to global warming because they may possess a narrow thermal tolerance range as a result of having evolved in a relatively stable thermal environment.” However, the results of this study indicate that damselfish have the capacity for thermal acclimation during development, allowing them “to cope with increases in water temperature without a substantial loss to performance”… Read More

Dry Heathland Response to Elevated CO2, Warming and Drought (20 Aug 2013)
In a CO2-enriched and warmer world of the future, the dry heathland ecosystem studied by Albert et al. should do much better than it does currently. And if significant summer droughts occur, it should do no worse than it does at the present time… Read More

Although the HadGEM1 does some things well, there are a number of other things that it has yet to satisfactorily accomplish… Read More

CO2 Enrichment Effects on Soil Nitrogen: Positive or Negative? (20 Aug 2013)
A long-term study rebuts the Progressive Nitrogen Limitation Hypothesis, revealing that there is good real-world experimental evidence to suggest that the growth-enhancing effect of atmospheric CO2 enrichment will not gradually wind down with the passage of time due to declining availability of soil nitrogen, in strong contradiction of what many climate alarmists have suggested… Read More

Invasions of Alien Plant Species: Spurred on by Global Warming? (21 Aug 2013)
Widely-expressed concerns about the possibility of CO2-induced global warming increasing the negative impacts of alien plant invasions has, as yet, no compelling basis in pertinent experimental studies… Read More

Proper Modeling of the Seychelles Dome: Is Progress Being Made? (21 Aug 2013)
A comparison of CMIP3 and CMIP5 model results reveals that “compared to the CMIP3 models, the CMIP5 models are even worse in simulating the dome longitudes”… Read More

Impacts of Atmospheric CO2 Enrichment on Salt-Stressed Barley (21 Aug 2013)
In the words of the authors who conducted this study, “barley plants subjected to elevated CO2 levels will likely overcome mild saline conditions because of their capacity to maintain efficiency in N metabolism,” which, of course, is good news for agricultural production of the crop species… Read More
