Fracture load of cantilevered implant‐supported prostheses of varying heights fabricated from additively and subtractively manufactured resins

Journal of Prosthodontics, EarlyView.
Abstract Purpose The purpose of this in vitro study was to evaluate the fracture load, both before and after aging, of implant‐supported cantilevered prostheses with different prosthesis heights fabricated additively using an experimental resin and a commercially available resin, or subtractively from a high‐impact polymer composite.

Canopy‐scale VPD reduction in a mature forest alters stomatal response to soil drought in Pinus sylvestris L.

New Phytologist, EarlyView.
In a mature Scots pine forest (Pfynwald, Switzerland), canopy vapor pressure deficit (VPD)a was reduced with a misting system (a) and combined with a throughfall‐exclusion roof that imposed soil drought (b). Under the roofs (c), trees at ambient VPD closed their stomata steeply as predawn water potential (ΨPD) fell, reaching closure around −1.2 MPa ...

Tropical leaf phenology as a thermoregulation trait: how changes in crown structure modulate thermal dynamics for two dominant Hawaiian trees

New Phytologist, EarlyView.
Study site and focal species. Summary Canopy and leaf temperatures often diverge from air temperature, influencing photosynthesis, water loss, and heat stress. While leaf traits are known to affect heat exchange, how changes in crown structure interact with environmental drivers to regulate canopy thermal dynamics is poorly understood, particularly in ...

Trait‐based plant ecology: some history and some future

New Phytologist, EarlyView.
Schematic of plant species range boundaries, some mechanisms that might set them, and some traits that might explain them. Summary Since around the year 2000, trait‐based ecology has become self‐aware as a strand of research within ecology. How did this happen? What is trait‐based ecology now? And where might it go in future?
