Dear colleagues,

We are pleased to announce that the following paper is now available online:

Enrico Pirotta, Leslie New and Marianne Marcoux (2018). Modelling beluga 
habitat use and baseline exposure to shipping traffic to design effective 
protection against prospective industrialization in the Canadian Arctic. 
Aquatic Conservation: Marine and Freshwater Ecosystems.

Abstract:

1. Global warming is predicted to reduce sea ice and thereby grant access to 
new shipping routes in the Arctic, leading to the expansion of human 
exploitation of natural resources in this region. The accompanying rise in boat 
numbers could impact the local populations of marine mammals by increasing 
collision rates and behavioural disturbance. It is therefore important to 
quantify the baseline exposure to current levels of shipping traffic and to 
understand how wildlife's important habitat overlaps with shipping lanes, in 
order to support appropriate spatial planning and management.
2. In this study, telemetry tracks from nine belugas (Delphinapterus leucas) 
tagged in Western Hudson Bay, which is home to the world's largest summer 
aggregation of this species, were used to estimate the habitat use of the 
animals and to map any overlap with current shipping activities.
3. Following a use‚Äďavailability design, with spatially adaptive smooths fitted 
using generalized estimating equations, beluga habitat use was quantified, 
confirming that they aggregate in coastal areas in association with river 
estuaries. The baseline exposure is low, and is concentrated around major 
harbours in the region.
4. Rising levels of traffic will increase anthropogenic pressure on Western 
Hudson Bay belugas. The approach presented here informs the design of effective 
spatial protection measures to minimize any potential consequence on the 
population.
