Linking community structure and climate vulnerability in desert plant assemblages of southern California

American Journal of Botany, EarlyView.
Abstract Premise Desert plant assemblages in southern California provide an opportunity to link patterns of community structure with climate‐driven vulnerability in a rapidly changing environment. California sustains an exceptionally diverse flora of approximately 4300 plant species, with 31% identified as endemic.

Arthroscopic Repair of Radial Meniscal Tear Using Fibrin Clot Augmentation and “Hashtag” Style Inside‐Out Technique

Arthroscopy Techniques, EarlyView.
Abstract Significant meniscal injuries lead to pain and possible early osteoarthritis development. Fibrin clot augmentation represents an effective, cost‐efficient method for improving healing rates in poorly vascularized meniscal tears. This arthroscopic technique shows fibrin clot augmentation combined with horizontal and vertical mattress sutures in

Surrogate‐Based Time‐Continuous Seismic Fragility Assessment of Corrosion‐Deteriorated Reinforced Concrete Bridges Under Climate Change

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Seismic fragility assessment of reinforced concrete (RC) bridges exposed to corrosive environments must reliably capture time‐dependent deterioration impacts. Climate change compounds this challenge through nonstationary temperature and humidity variations that accelerate bridge corrosion.
