Dear colleagues,
the following paper is now available online:
Panigada et al. 2017. Satellite tagging of Mediterranean fin whales: working
towards the identification of critical habitats and the focussing of mitigation
measures. Scientific Reports.
Abstract
Mediterranean fin whales comprise a genetically distinct population, listed as
Vulnerable (VU) in the IUCN Red List. Collisions with vessels are believed to
represent the main cause of human-induced mortality. The identification of
critical habitats (including migration routes) incorporating satellite
telemetry data is therefore crucial to develop focussed conservation efforts.
Between 2012 and 2015 thirteen fin whales were equipped with satellite
transmitters, 8 in the Pelagos Sanctuary (although two ceased within two days)
and 5 in the Strait of Sicily, to evaluate movements and habitat use. A
hierarchical switching state-space model was used to identify transiting and
area-restricted search (ARS) behaviours, believed to indicate foraging
activities. All whales undertook mid- to long-distance migrations, crossing
some of the world’s busiest maritime routes. Areas where the animals
predominantly engaged in ARS behaviour were identified in both study areas. The
telemetry data were compared with results from ecosystem niche modelling, and
showed that 80% of tagged whale positions was near (<7 km) the closest suitable
habitat. The results contribute to the view that precautionary management
should include establishment of a coordinated and dynamic basin-wide management
scheme; if appropriate, this may include the establishment of protected areas
by specific regional Conventions.
