Disrupting the herd: Recreational boating alters group dispersion within beluga whale herds

open access: yesThe Journal of Wildlife Management, EarlyView.
Recreational boating in beluga habitat remains poorly documented. Using land‐based observations in the Saguenay Fjord (Quebec, Canada), we show that increasing recreational boat numbers are associated with a higher probability of changes in beluga herd dispersion, suggesting behavioral disturbance and the need to integrate recreational boating into ...

Isolation, Insularity and Resilience: A Review of the Geophysical, Socioeconomic, and Environmental Vulnerabilities of Gran Canaria and Lesvos Islands for Policy Interventions to Global Change

open access: yesSustainable Development, EarlyView.
ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.

A new method for calculating fuel consumption and displacement of a ship in maritime transport

open access: yes, 2017
Fuel consumption is the most important parameter which is effected by the petrol prices. Optimization of the sailing speed decreases the fuel cost because it is proportional to the sailing speed.
