Viability analysis and the importance of fine‐scale variables influencing roadkills of a toad population

The Journal of Wildlife Management, EarlyView.
Fine‐scale population variables better explain roadkill patterns in natterjack toads (Epidalea calamita) than habitat proxies, with mortality driven mainly by local abundance, reduced by roadside embankments, and decreasing as the season advanced. Despite high roadkills, population viability analyses indicate no immediate extinction risk under current ...

Estimating the damage and marginal cost of different vehicle types on rail infrastructure: combining economic and engineering approaches [PDF]

, 2014
EU legislation requires that European infrastructure managers set access charges based on the marginal cost of running trains on their networks. Two methods have been used in the literature for this purpose.

An Elasto–Plastic Hydro–Mechanical Model for Analyzing the Swelling Behavior of Heterogeneous Clay–Sulfate Rocks

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Swelling of clay‐sulfate rocks is a concern in geotechnical engineering that can damage infrastructure. In the historic town of Staufen in southwest Germany, geothermal drilling into a swellable anhydrite‐bearing clay formation resulted in water inflow and subsequent swelling, triggering ground heave and damage to more than 250 houses.

Urban wild meat and pangolin consumption across southern forested Cameroon: The limited influence of COVID‐19

People and Nature, EarlyView.
Abstract Overexploitation of wildlife is pervasive in many tropical regions, and in addition to being a significant conservation and sustainability concern, it has received global attention given discussions over the origins of zoonotic disease outbreaks.

Impact of cold climate on failures in railway infrastructure [Elektronisk resurs]

, 2012
Railway traffic has increased over the last decade due to greater energy costs and the need to reduce emissions. Ensuring the dependability and capacity of railway infrastructure requires efficient and effective maintenance which, in turn, requires good ...

Plurality in transformative change: Three co‐created pathways toward nature‐positive Europe(s)

People and Nature, EarlyView.
Abstract The accelerating decline of biodiversity necessitates transformative change to protect nature and society, which requires innovative actions and governance strategies. This paper advances the conceptual understanding of transformative change by identifying patterns of change in three co‐created transformative pathways for a nature‐positive ...

Research on the Dynamic Response of the Catenary of the Co-Located Railway for Conventional/High Speed Trains in High-Wind Area

Infrastructures
To establish a theoretical foundation for assessing the dynamic performance of high-speed train catenary systems in wind-prone regions, this study develops a coupled pantograph–catenary model using ANSYS(2022R1) APDL.
