What's in It for Them? A Developmental Science Perspective on Adolescent Climate Activism

open access: yesJournal of Adolescence, EarlyView.
ABSTRACT Introduction In recent years, millions of adolescents have joined school strikes to demand climate action from governments and industries, standing in solidarity with young people from future generations and from vulnerable geographical regions (i.e., the Global South).

Evaluating Erosional Stability of Reconstructed Mine Landscapes Using Landform Evolution Models: Parameterisation and Decadal‐Scale Erosion Assessment

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Ensuring the long‐term erosional stability of post‐mining landforms remains a major challenge in open‐pit mining. Reconstructed landscapes must support the agreed post‐mining land use, such as cattle grazing in the Hunter region of southeastern Australia, requiring stable pasture and minimal soil loss.

Global analysis of annual survival among shorebirds reveals a negative effect of migration distance and a decline in recent decades

open access: yesOikos, EarlyView.
Annual survival is a key demographic parameter driving population trends in wildlife populations. However, despite numerous species‐specific or regional studies, global reviews of the factors affecting the survival of declining taxa remain scarce. Here, we investigated annual survival of fledged immature and adult shorebirds, a globally‐distributed and

Experimental Study on Performance of High-Performance Concrete Based on Different Fine Aggregate Systems

open access: yesBuildings
To advance the adoption of manufactured sand, this study investigated concrete mix designs wherein manufactured sand partially substituted natural river sand and fully replaced fine aggregates. The influences of the water–binder ratio and fly ash content

Understanding the effects of patch‐burn grazing management on aboveground grassland invertebrate biodiversity

open access: yesOikos, EarlyView.
Landscape heterogeneity is widely recognized as a driver of biodiversity, yet its consequences for above‐ground, foliage‐dwelling insect communities under active grassland management remain underexplored. Patch‐burn grazing (PBG), which rotates fire across patches within a grazed landscape, is designed to promote spatial and temporal heterogeneity by ...

Dress for success: climate pressures predict fur insulation and body size in natural and reintroduced populations of a threatened marsupial

open access: yesOikos, EarlyView.
Phenotypic variation in functional traits underpins responses to environmental gradients, influencing thermoregulation, energy balance, and long‐term persistence under climate extremes. Climate change is altering these gradients globally, yet in species that have already disappeared from much of their range, adaptive phenotypes may have also been lost,
