Natural and Geomorphological Response of the Small Lowland River Valley for Anthropogenic Transformation

open access: yesResources, 2021
The regulation of small rivers and the consequent maintenance works are common in the Central European Lowlands. This article attempts to determine the relationship between the invertebrate fauna (and consequently the biocenosis) of the small lowland ...

Land birds on atolls: diversity, origin, and function

open access: yesBiological Reviews, EarlyView.
ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

Glacial Geomorphology of southern Alberta, Canada [PDF]

open access: yes, 2009
During deglaciation from the Last Glacial Maximum three terrestrial ice streams within the south western sector of the Laurentide Ice Sheet competed and coalesced in southern Alberta; the High Plains Ice Stream (HPIS), Central Alberta Ice Stream (CAIS ...

When Nature Counts: Corporate Biodiversity Attention and Access to Bank Finance

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This paper investigates whether corporate attention to biodiversity influences firms' access to bank loans, an overlooked question in the emerging biodiversity–finance literature. Using a novel, text‐based measure constructed from 446 biodiversity‐related keywords and applied to Chinese A‐share listed firms from 2000 to 2023, we show that ...

3D Landform Modeling to Enhance Geospatial Thinking

open access: yesISPRS International Journal of Geo-Information, 2019
Geospatial thinking is essential to the visualization⁻interpretation processes of three-dimensional geographic information. The design of strategies for the interpretation of the Earth’s surface which allow the development of students’ ...

Upper bound limit analysis of coral reef limestone cavern roof stability incorporating a tension‐shear failure mechanism with tensile‐strength cut‐off

open access: yesDeep Underground Science and Engineering, EarlyView.
For the roof of coral reef limestone caverns, a novel tension‐shear composite failure mechanism was developed. The most critical tensile crack model was identified using a hybrid optimization algorithm, and the stability of the cavern roof was analyzed accordingly.

Small-scale opencast mining: an important research field for anthropogenic geomorphology

open access: yesDIE ERDE: Journal of the Geographical Society of Berlin, 2015
Artisanal and small-scale mining (A&SM) is a growing economic sector in many third-world countries. This review focuses on anthropo-geomorphic factors and processes associated with small-scale opencast mining (SSOM), a form of A&SM in which near-surface ...

Taxon‐dependent multisite species turnover in fragmented habitats: comparing zeta diversity across birds, butterflies, and cursorial hunting spiders

open access: yesEcography, EarlyView.
Habitat fragmentation alters species diversity and reshapes community composition. However, conventional pairwise approaches to compositional variation (i.e. beta diversity metrics) do not explicitly characterize how species sharing or turnover change with the number of habitat patches.

Geochronological reconstruction of the Lateglacial deglaciation in the Arve Valley (Northern French Alps)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The timing and spatial patterns of glaciers retreat in the Northern French Alps during the Lateglacial (19.0–11.7 ka) remain debated, reflecting discrepancies among available chronological data sets. The complex interactions between major glaciers, such as the Rhône and Arve glaciers to the north and the Isère glacier to the south, represent a

Geomorphometric tool associated with soil types and properties spatial variability at watersheds under tropical conditions

open access: yesScientia Agricola, 2016
The application of quantitative methods to digital soil and geomorphological mapping is becoming an increasing trend. One of these methods, Geomorphons, was developed to identify the ten most common landforms based on digital elevation models. This study
