Road air pollution harms the reproductive success of a bee‐pollinated wildflower: A dusty threat to biodiversity

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Dust, a common form of air pollution, is particularly problematic on roadsides, which are important habitats for plants and pollinators. We investigated whether and how road dust affects plant sexual reproduction using Primula chungensis in a biodiversity hotspot. Our study provides compelling evidence that road dust can harm plant reproductive success

Hydropower Operations Reduce Alluvial Nesting Habitat and Alter Riverine Turtle Population Demographics

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Hydropower management has altered discharge regimes of large rivers worldwide, reducing sediment mobilization and early‐seral conditions essential for many riverine species. Spiny softshell turtles (Apalone spinifera) rely on alluvial habitats for nesting and may serve as sentinel species to assess the effects of regulated flow regimes and ...

Innovative development and structural behavior of hollow columns using inflatable molds

open access: yesStructural Concrete, EarlyView.
Abstract This study introduces a novel approach for constructing hollow columns using precast (PC) methods enhanced by inflatable air tubes as internal molds. The proposed method addresses practical challenges in conventional hollow column construction, such as limited constructability, high production cost, and interference between internal molds and ...

Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

open access: yesStructural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...
