Tree Squirrels Selectively Disperse High‐Quality Acorns Away From Tree Trunks

Integrative Zoology, EarlyView.
Acorn quality and squirrel feeding behavior significantly structured spatial dispersal patterns of two Californian oak species. Non‐infested acorns were preferentially selected for embryo excision and dispersed farther than infested ones. Acorns were fully consumed near tree trunks, signaling rapid feeding in safe refuges, whereas non‐eaten, partially ...

A New Fine-Scale Berry-Esseen-Type Gumbel-Limit Theorem for Multivariate Maxima [PDF]

For d ≥ 2 and i.i.d. d-dimensional observations ^(1), ^(2), … with independent Exponential(1) coordinates, let φ_n denote the minimum ¹-norm among the maxima of {^(1), …, ^(n)}. (A maximum from this set is an observation ^(k) with 1 ≤ k ≤ n such that ^(k)

Nocturnal Behavior of Wintering Common Cranes (Grus grus) Under Varying Environmental Conditions

Integrative Zoology, EarlyView.
For diurnal species, nighttime represents a critical ecological boundary. Understanding the ecological determinants of nocturnal activity in taxa traditionally regarded as inactive after dusk is essential for elucidating the adaptive significance of nighttime behavior. We examined how night phase, nocturnal brightness (moon illumination and cloud cover)

Resource-efficient composite foundations using steel slag concrete piles: Field performance and microstructural evidence

Cleaner Materials
Steel slag concrete (SSC) piles represent a resource-efficient option for ground improvement as they valorize steelmaking by-products and reduce dependence on conventional cement and natural aggregates.

A validated 3D point‐cloud analysis workflow for the creation of seagrass canopy height models

Methods in Ecology and Evolution, EarlyView.
Abstract Seagrasses support highly productive ecosystems in both temperate and tropical waters and provide essential ecosystem services. Despite their importance, the vertical structure of seagrasses (i.e. the canopy) remains poorly characterised at the microscale, even though it is a strong predictor of ecological processes that influence both ...

The specifics of non‐routine task changes: A granular approach

Contemporary Economic Policy, EarlyView.
Abstract This paper estimates granular specific non‐routine tasks and examines employment reallocation across those tasks in the United States. Employment shifts into decision‐making, technology, and information‐related tasks account for 90% of high‐wage employment growth.

Dive surveys and eDNA detect contrasting macroalgal community composition in Nova Scotia, Canada

Journal of Phycology, EarlyView.
Abstract Morphological identification of macroalgae can be time‐consuming and species may be difficult to observe, collect, or identify, preventing detailed study on the distribution and ecology of many species. The use of eDNA in species surveillance and biodiversity assessments has gained considerable traction in studying macroalgae, as it provides ...

Study on the effect and mechanism of hot-air-boosted vacuum preloading solidification of dredged silt via model tests

Applied Ocean Research
The traditional vacuum preloading method (TVP) is improved, and a “hot-air-boosted vacuum preloading (HAVP) method”, which combines vacuum preloading with hot gas injection into soil for heating, is proposed. The thermal‒mechanical coupling consolidation

Target Trial Emulation in Observational Research—Strengths, Limitations, and Methodological Considerations

Journal of Periodontal Research, EarlyView.
The target trial framework is a pragmatic roadmap for observational causal inference that clarifies questions, mitigates time‐related bias, and improves interpretability while acknowledging limits. With transparent protocols, appropriate methods, and suitable data, it can complement randomized trials and inform practice and policy.

That sinkin’ feeling: Environmentally induced distress on a disappearing island

Medical Anthropology Quarterly, EarlyView.
Abstract Residents of Tangier Island, Virginia, a subsiding island in the Chesapeake Bay, embody psychosocial dimensions of environmental change. Analysis of ethnographic data shows islanders’ experiences and articulations of anxiety, panic, and despair as “that sinkin’ feeling,” resulting from the stress of living with the long‐term threat of imminent
