Macro–Micro Correlation Mechanism Between Structural Potential and Mechanical Strength in Collapsible Loess

Buildings
The collapsibility of loess in the northwest region poses a significant threat to infrastructure stability. Current research predominantly separates macroscopic mechanical behaviour from mesoscopic structural characteristics, lacking a systematic ...

Tracking potential source areas of Central European loess:examples from Tokaj (HU), Nussloch (D) and Grub (AT)

Open Geosciences, 2015
There are several competing hypotheses for theorigin of loess in Europe but quantitative evidence is stillrare. Here, Sr-Nd isotopic and bulk elemental compositionof loess from Marine Isotope Stages 2 and 3 fromthree study regions in Central Europe ...

Veronica paczoskiana is no more than a pine forest ecotype of V. spicata that evolved independently in forest‐steppes of Ukraine and the Altai region

Nordic Journal of Botany, EarlyView.
The Eurasian steppe area has been a dynamic vegetation biome during the Pleistocene with its repeated cycles of forest advances and retreats. Such a scenario allows the evolution of ecotypes at the ecotone with the potential for parallel evolution in different parts of the distribution area.

Analysis of crack development in loess deep filled ground based on physical modelling tests

Zhongguo dizhi zaihai yu fangzhi xuebao
Cracks are a common issue in deep filled construction projects, and conventional methods often struggle to accurately predict their development. To guide the anti-crack design for deep-filled loess projects, a prototype of a typical gully section from a ...

Landscape Dynamics in the Caspian Lowlands Since the Last Deglaciation Reconstructed From the Pedosedimentary Sequence of Srednaya Akhtuba, Southern Russia

Geosciences, 2018
Surface Kastanozem of the Lower Volga area was first studied as a part of the pedocomplex, with the lower part (148⁻160 cm) formed in Early Khvalynian Chocolate clays (13⁻15 ka), the middle part (100⁻148 cm) in a mixed clay-loess ...

Permafrost Mass Wasting in Ice‐Rich Landscapes: Recent Advances (2013 to 2024) on Mechanisms, Dynamics and Impacts

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Across circumpolar permafrost regions, climate change is destabilizing ice‐rich hillslopes, increasing the frequency and magnitude of thaw‐driven mass wasting. This paper reviews recent studies (2013–2024) on thaw‐driven mass wasting, focusing on the processes, morphology and trajectories of geomorphic change and their implications for ...

Implementing potential climate‐smart practices through diverse partnerships

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change is one of the greatest threats to society, negatively impacting agriculture and crop yields. Globally, agriculture is also one of the largest greenhouse gas (GHG) emitting sectors. Climate‐smart practices that are developed through diverse partnerships with scientists and practitioners are needed to decrease GHG emissions. We implemented

Using dendroclimatic analysis of exotic deciduous conifers in an arboretum to document tree growth in response to climate change, Northeast Ohio, USA

PLANTS, PEOPLE, PLANET, EarlyView.
Rising temperatures and wetter conditions in the Midcontinent of North America are influencing climate responses in trees. Dendroclimatological analyses of four exotic deciduous conifer species from Secrest Arboretum, Northeast Ohio help identify past, present and future climate‐tree interactions.
