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 regul...

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, wh...

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 physiolog...

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...

38: 595-607. The commercial production of orchids has been growing steadily in recent years, with particularly high demand among the genus Phalaenopsis. Consequently, the floricultural industry has begun investigating the response of Phalaenopsis cultivation under varying environmental conditions, including atmospheric CO 2 enrichment. The present review examines the work of Cho et al. (2020), who studied the response of two Phalaenopsis cultivars (Queen Beer Mantefon and Queen Beer Jupiter) to elevated CO 2 and nutrient supply over a period of 21 weeks. The experiment was conducted in a ...
