Paper Reviewed Kim, J.-H., Kim, N., Moon, H., Lee, S., Jeong, S.Y., Diaz-Pulido, G., Edwards, M.S., Kang, J.-H., Kang, E.J., Oh, H.-J., Hwang, J.-D. and Kim, I.-N. 2020. Global warming offsets the ecophysiological stress of ocean acidification on temperate crustose coralline algae. Marine Pollution Bulletin 157: 111324. Crustose coralline algae (CCA) are calcifying seaweeds that inhabit intertidal and subtidal zones all across the ocean. They are ecologically important in that they contribute to primary production and carbonate sand production, facilitate invertebrate larval settlement and provide habitat for numerous marine species. Given such contributions to coastal habitats and systems ecology, Kim ....
Strawberry ( Fragaria ananassa) is a popular fruit known for its rich nutrition and sweet taste. In a previous study Zhao et al. (2018) reported that elevated CO 2 improved strawberry fruit growth, yield and quality. Now, in a follow up paper, Li et al. (2020) explored the physiological and molecular mechanisms driving such changes. In doing so they examined the growth rate and photosynthetic indices in strawberry leaves under ambient and elevated CO 2, while also performing transcriptome profiling by RNA sequencing on leaves from the two CO 2 treatments in an effort to elucidate gene regulation of photosynthesis in a CO 2-enriched environment. The work was conducted in the Chinese Solar Greenhouse of Shanxi Agricultural University (China). Plants were grown under normal greenhouse production methods at CO ....
2 and climate on intrinsic water-use efficiency in South Asian tropical moist forest trees. Tree Physiology 40: 904-916. Numerous scientific studies have been conducted in both laboratory and field environments to examine the impact of rising atmospheric CO 2 on plant water use efficiency (WUE). In nearly all instances those studies reveal rising CO 2 improves plant WUE, typically by reducing plant stomatal apertures, which reduces water lost to the air via transpiration. Consequently, at higher levels of CO 2, plants tend to need less water to produce the same (or more) amount of tissue, which portends great benefits for the future of agricultural production, especially in arid and irrigated regions. ....
Paper Reviewed Doo, S.S., Leplastrier, A., Graba-Landry, A., Harianto, J., Coleman, R.A. and Byrne, M. 2020. Amelioration of ocean acidification and warming effects through physiological buffering of a macroalgae. Ecology and Evolution, DOI: 10.1002/ece3.6552. The overwhelming majority of ocean acidification studies conducted to date involve assessing potential impacts on a given species in isolation. In the words of Doo et al. (2000), this is unfortunate and problematic because such experiments do not capture ecologically relevant scenarios where the potential for multi-organism physiological interactions is assessed. Such relevant scenarios include the operation of compensatory mechanisms whereby interactions between multiple organisms allow for physiological modification to buffer against stress and maintain ecological equilibria. For example, Doo ....
Paper Reviewed Ahmad, S., Israr, M., Liu, S., Hayat, H., Gul, J., Wajid, S., Ashraf, M., Baig, S.U. and Tahir, A.A. 2020. Spatio-temporal trends in snow extent and their linkage to hydro-climatological and topographical factors in the Chitral River Basin (Hindukush, Pakistan). Geocarto International 35: 711-734. Among the seemingly endless predictions of climate alarmism is the concern that rising temperatures are reducing planetary snow cover. But is this correct? A recent paper by Sun et al. (2020) suggests it is not, reporting instead that a large portion of Eurasia shows no significant positive or negative interannual trends of snow cover extent from 2000 to 2016. In the present review, we report the findings of another peer-reviewed paper published in 2020 that also undermines climate alarmist claims. ....
