Native habitat affinities predict fish invasions with post‐invasion habitat shifts

Journal of Animal Ecology, EarlyView.
Initial invasion success is gated by native pre‐adaptations, but post‐invasion establishment is characterized by habitat shifts. We demonstrate that forecasting risk based solely on native niches severely underestimates future ecological impacts, and we provide an empirically validated watchlist of future invaders.

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 ...

Consolidation Theory Selection of Dredger Fill

International Journal of Materials Science and Technology Studies
The theoretical study of blow fill is of great significance for the increasing land reclamation projects year by year. Through reading the online literature, combining the physical properties of the blown fill and the existing consolidation theory, the consolidation theory suitable for most scenarios of the blown fill is selected, and the advantages ...

Making Mining Licit: Gold, Commodification, and the Everyday Performance of Law in Colombia

American Anthropologist, EarlyView.
ABSTRACT Ethnographies of resource‐making have shown that the extraction of resource value from objects is premised on obviating the emplaced lifeworlds that surrounded objects before they traveled to consumer markets. Much of this literature looks at such supply‐chain disentanglement from the viewpoint of corporate and formal regulatory practices ...

Soil Parameter Inversion in Dredger Fill Strata Using GWO-MLSSVR for Deep Foundation Pit Engineering

Buildings
Accurate determination of constitutive model parameters is crucial for reliable numerical simulation in deep foundation pit engineering. This study presents an inverse analysis method using Multioutput Least-Squares Support Vector Regression (MLSSVR ...

Seepage and Consolidation Characteristics of Dredger Fill

Scientific Journal of Technology
The consolidation process of dredger fill is the process of soil particles from disorderly and irregular arrangement to orderly and regular arrangement until flocculation and formation of more stable soil structure. In the project, it is an urgent problem to shorten the sedimentation consolidation time and make the dredger fill change from the slurry ...

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.

Threatened cockatoo adapts foraging strategy to survive habitat loss from fire

Ibis, EarlyView.
Fire regimes are changing across the globe as a result of human‐induced climate change. For granivorous bird species, changes in fire regimes can affect seed availability and the persistence of populations. We investigated the foraging behaviour of Glossy Black Cockatoos Calyptorhynchus lathami halmaturinus, a resource specialist, following large‐scale

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

Dietary flexibility and high arthropod availability prevent food limitation in a mountain population of breeding Northern Wheatears

Ibis, EarlyView.
Mountain ecosystems are under strong environmental pressure and are considered highly vulnerable to climate change, which is likely to lead to forest expansion and loss of open alpine grasslands, threatening many specialized species. However, for most alpine birds, even basic ecological knowledge, such as their diet, remains limited, restricting our ...
