Hydrology Paper of the Day @seanmichaletz.bsky.social on why physical cutting of branches for leaf gas exchange measurements affects xylem water potential: quantification of processes in 26 species; utilization of the unified stomatal optimization model; hypotheses of processes; and mitigation.

Does branch excision bias our #photosynthesis data? New paper led by #MarcellaCross shows excision increases water potential but reduces photosynthesis in most species, with trait-dependent effects, so excised branches underestimate intact rates. www.researchgate.net/publication/... #MichaletzLab

Online now: A systems modelling approach to predict biological responses to extreme heat

A systems modelling approach to predict biological responses to extreme heat

Anthropogenic climate change is leading to more frequent and extreme heat waves. These large-scale events are radically reshaping interactions among organisms—impacting biodiversity, community composition, and ecosystem services crucial to natural systems and food security. Predicting heat wave impacts on interacting species requires an understanding of the processes driving differential exposure and sensitivity of organisms to extreme heat events in a life cycle context. To achieve this predictive capacity, we need to integrate models across scales while capturing species-specific responses at the individual level. We review and demonstrate how existing models in disparate fields can be linked to achieve an increased understanding of how individuals and communities will respond to extreme heat, now and into the future.

It’s official! We’re springing forward just one more time, and then we’re adopting permanent daylight savings time in BC. 🕰️ That means more sunshine and better sleep for people across our province.

My department at CSU Northridge is hiring a vertebrate functional morphologist! We've got a great EEB group, and we're looking for someone to carry forward a tradition of enriching organismal courses and community-engaged research. App review starts March 15 csucareers.calstate.edu/mob/cw/en-us...
