Forging environmentalism: The influence of childhood nature experiences on people's pro‐biodiversity value orientations and attitudes

open access: yesPeople and Nature, EarlyView.
Abstract With the rapid expansion of transnational biodiversity policy instruments promoting large‐scale landscape transformations that depend on public support for their success and feasibility, understanding the mechanisms underlying pro‐biodiversity attitudes has become important.

System Reliability Analysis of Slope Stability of Earth Rock Dams Based on Finite Element Strength Reduction Method

open access: yesApplied Sciences
To overcome the limitations of rigid body limit equilibrium methods in earth rock dam slope stability analysis, this study develops a system reliability framework using the finite element strength reduction method (FEM-SRM).

Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.

PCR‐based species identification tools for wireworms (Coleoptera: Elateridae) of economic importance in Canada

open access: yesPest Management Science, EarlyView.
Species‐specific PCR primers and PCR‐based assays were designed for the identification of 15 economically important and difficult to distinguish wireworm pests in Canada. PCR specificity testing and performance assessments confirm the accuracy of the assays.

Effect of Different Core Slopes and Filters on Seepage for Horan Dam, Iraq

open access: yesمجلة النهرين للعلوم الهندسية
A dam failure results in losses in terms of economy and infrastructure, in addition to the loss of many lives and assets. Inadequate seepage control procedures are typically the cause of seepage failure in earth-fill dams.

Restoring Lateral Connectivity to Anthropogenic Riverscapes: Six Lessons From Stage Zero

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Centuries of river modification, particularly straightening and incision, have severely reduced lateral connectivity between rivers and their floodplains. As a result, Stage 0 riverscapes, characterised by high lateral connectivity (e.g., anastomosing or wetland riverscapes), are now rare in anthropogenic landscapes.

Study on Deformation Characteristics of Gate Dam and Earth–Rock Dam Systems with Deep Overburden

open access: yes
Gate dam and earth–rock dam systems have many advantages, such as minimal ecological impact and good terrain adaptability, making them the preferred dam type for low-head, high-flow river areas with thick overburden layers. This study, based on an ongoing construction project, pioneers a comprehensive three-dimensional stress–deformation characteristic

Forensic Hydraulic Analysis of Floodplain Connectivity Driven by Historical Beaver Dams in Colorado Headwater Streams

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT As ecosystem engineers, beavers (Castor canadensis) modify river corridor form through dam building. When beavers are removed from a river corridor, their unmaintained dams wash out, altering the stream's hydrologic regime. The assumption that beaver dams increase floodplain connectivity is frequently presumed but has not been directly ...

Study on Deformation Characteristics of Gate Dam and Earth-Rock Dam System on Deep Overburden

open access: yes
The gate dam and earth-rock dam system offers advantages such as minimal ecological impact and strong terrain adaptability, making them the preferred dam type for low-head, high-flow river areas with thick overburden layers. This study, based on a ongoing construction project, pioneered a comprehensive three-dimensional stress-deformation ...

A Multi‐Method Approach to Assessing Barrier Effectiveness in Preventing the Spread of Invasive Signal Crayfish (Pacifastacus leniusculus)

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Relieving barriers and increasing free flowing rivers is a global imperative to restore habitat connectivity for migratory fish stocks. While reducing river fragmentation will certainly improve biodiversity, the spread of non‐native species throughout a river system may be facilitated as an inadvertent outcome.
