River Research and Applications, EarlyView.ABSTRACT As ecosystem engineers, beavers (Castor canadensis) modify river corridor form through dam building. When beavers are removed from a river corridor, their unmaintained dams wash out, altering the stream's hydrologic regime. The assumption that beaver dams increase floodplain connectivity is frequently presumed but has not been directly ...

Obesity Reviews, EarlyView.ABSTRACT Achieving and maintaining weight loss are challenging and require sustained lifestyle changes. This study examined which behavior change techniques (BCTs) support long‐term weight outcomes among adults with overweight or obesity. We synthesized evidence from randomized controlled trials of behavioral interventions versus control or alternative

Lack of Hydraulic Acclimation in Response to Multiple Droughts and Recovery
Plant, Cell &Environment, Volume 49, Issue 9, Page 6931-6943, September 2026.ABSTRACT Human‐caused climate change is expected to bring more frequent and extended droughts with shorter wet periods of relief in between for many regions of the world. Critical knowledge gaps remain around the extent to which tree species can acclimate physiologically to repeated droughts.
