Leaf photosynthetic and morphological traits underlie heat stress resilience in northern highbush blueberry (Vaccinium corymbosum L.)

open access: yesEnvironmental and Experimental Botany
Northern highbush blueberry (Vaccinium corymbosum L.) is a temperate fruit crop increasingly exposed to heat stress as heatwaves become more frequent. This suggests the need to characterize thermotolerance traits to facilitate sustainable production.

The effects of single versus successive warm summers on an intertidal community

open access: yesOikos, Volume 2026, Issue 6, June 2026.
To accurately predict how organisms and ecological communities will respond to future conditions caused by climate change, we must consider the temporal dynamics of environmental stressors, including the effects of repeated exposures to stress. We performed a two‐year passive thermal manipulation in coastal British Columbia, Canada to determine how ...
