Flood findings: Tropical Storm Irene informs Dartmouth student’s study of rivers Jordan Fields, a doctoral student of fluvial geomorphology, left, and Dartmouth College senior Shannon Sartain, right, work together to plot changes to the channel of Charles Brown Brook in Norwich, Vt., Wednesday, April 14, 2021. Fields is studying the recovery of the site following the 2018 removal of a dam built almost 100 years earlier. (Valley News - James M. Patterson) Copyright Valley News.

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 p...

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...
