Abstract |
Abstract 1. Industrial fisheries represent one of the most serious threats worldwide to seabird conservation. Death of birds in fishing operations (i.e. bycatch) has especially adverse effects on populations of albatrosses, which have extremely low fecundity. 2. The single population worldwide of Amsterdam albatross (Diomedea amsterdamensis) comprises only 167 individuals and risks considerable decline over the mid?term from additional mortality levels potentially induced by fisheries. The priority actions listed in the current conservation plan for this species included characterizing the longline fisheries operating within its range, dynamically analysing the overlap between albatrosses and these fisheries, and providing fisheries management authorities with potential impact estimates of longline fisheries on the Amsterdam albatross. 3. During all life?cycle stages and year quarters the birds overlapped extensively with fishing effort in the southern Indian and Atlantic oceans. Fishing effort, and consequently overlap score (calculated as the product of fishing effort and time spent by the birds in a spatial unit) was highest in July?September (45% of the hooks annually deployed). Just three fleets (Taiwanese, Japanese and Spanish) contributed to >98% of the overlap scores for each stage (72% from the Taiwanese fleet alone, on average). Daily overlap scores were higher for the non?breeding versus the breeding stages (3?fold factor on average). 4. Based on previous bycatch rates for other albatross species, this study estimated that longline fisheries currently have the potential to remove ~2?16 individuals (i.e. ~5%) each year from the total Amsterdam albatross population, depending on whether bycatch mitigation measures were or were not systematically employed during the fishing operations. 5. Recent bycatch mitigation measures may be instrumental in the conservation of the Amsterdam albatross. This study suggests three further key recommendations: (1) to focus conservation efforts on the austral winter; (2) to require all operating vessels to report ring recoveries; and (3) to allocate special regulation of fishing operations in the areas of peak bycatch risk for the Amsterdam albatrosses.

Abstract |
Inuit contemporary mobility in Northern Canada is usually understood as either traditional travelling “on the land” (as the Inuit say) or the decision to move from one settlement to another or to a non-Arctic town, a change of residence which is at least partly surveyed by Canada's regular Censuses.
But an important part of Inuit contemporary mobility is ignored: their travels to un-familiar or less familiar places, i.e.: all the trips that an increasing number of Inuit take either to other Inuit communities or to Southern Canadian towns, or even to places abroad. These trips are taken for a number of very different reasons such as health treatment (including childbirth), meetings, sports tournaments, festivals and local jamborees, temporary job, training, visiting, but also Christmas shopping and holiday breaks.
This form of mobility has greatly increased and has become more complex in the last 20 years, in terms of range and network. It is also an important part of Inuit lives in Northern communities, for those who do travel as well as for those who do not, or very rarely. Yet, there is hardly any data available on these movements, which appear to be overlooked by anthropologists, cultural geographers and demographers alike.
Based on first hand geographic and ethnographic information collected formally in Feb-March 2013 and informally during various field-work campaigns since 1986 in Western Nunavut and the NWT I will present an overview of these travels as experienced in that area and discuss how this new form of ordinary mobility is reshaping family networks, gender relations and local politics in Inuit communities. I will also argue that mobility is part of Inuit well-being and how economic development programs as well as wellness programs could, and should, take it into account.
