Using a live‐streaming webcam to assess the behavioural responses of waterbirds to changes in the density of swans Cygnus spp.

Wildlife Biology, EarlyView.
Wildlife research has benefitted from the development of new methods that allow data to be collected remotely, with less disturbance to focal animals. The proliferation of livestreaming webcams, for example, those used by nature reserves for public engagement purposes, have offered new possibilities for the study of wildlife behaviour.

Étude des impacts hydrauliques, sédimentologiques et écologiques liés aux travaux hydrauliques sur la Semois

Belgeo, 2003
This study aims to evaluate impacts of riverbed dredgings in the Semois catchment (Ardenne). This is an interdisciplinary study focused on the hydraulic, environmental, geomorphological and sedimentological aspects.

The wolf is back! Non‐consumptive effects of the return of a large carnivore on the use of supplementary feeding sites by roe deer

Wildlife Biology, EarlyView.
Understanding how prey species tradeoff predation risk and resource acquisition is particularly important for advancing our knowledge of predator–prey relationships. We investigated this by studying the use of concentrated anthropogenic resources, namely supplementary feeding sites, by roe deer Capreolus capreolus before and after grey wolf Canis lupus

Optimization of desilting construction scheme for pile foundation wharves considering structural safety

Shuili Shuiyun Gongcheng Xuebao
The severe issue of sediment redeposition under pile foundation wharves along China’s silty coastal shores leads to damage to the pile foundations and high silt dredging costs.

Sustainable sediment management in Jordanian dams: Feasibility, economic viability, and agricultural reuse potential [PDF]

Journal of Water and Land Development
Jordan has long faced severe water scarcity, which has significant implications for agriculture, industry, and domestic consumption. This crisis is further exacerbated by climate change, population growth, regional conflicts, and unsustainable water use.

Development of ± 550 kV DC GIS Basin Insulator

High Voltage, EarlyView.
ABSTRACT The basin insulator is a core component of the insulation system for ± 550 kV gas‐insulated switchgear (GIS). This paper, using a finite element method for multi‐physics simulations of electric–thermal coupling, determines a geometry suitable for the industrial production of ± 550 kV GIS basin insulators.

Impact of Klaipėda port jetties reconstruction on adjacent sea coast dynamics / Rekonstruotųjų klaipėdos uosto molų įtaka gretimų jūros krantų dinamikai

Journal of Environmental Engineering and Landscape Management, 2012
During the reconstruction of 2001–2002, the Klaipėda port jetties were lengthened (the northern jetty by 205 m and the southern by 278 m). These works produced an impact on dynamic coastal processes in the neighbourhood of the port. The evaluation of the

Phenology drives asymmetric responses of ecosystem productivity stability to warming and cooling

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem productivity stability is a key indicator of ecosystem functioning under climate change, but the role of cooling periods in increasingly variable climates remains poorly resolved.
