I would like to post on the MARMAM list the following announcement:
Subjetc: NEW PAPER Predictive habitat models to manage MPAs
We are pleased to announce the publication of the following paper in
the Ocean and Coastal Management:
Azzellino A., Panigada S., Lanfredi C, Zanardelli M., Airoldi, S. and
Notarbartolo di Sciara, G. 2012. Predictive Habitat Models For
Managing Marine Areas: Spatial And Temporal Distribution Of Marine
Mammals Within The Pelagos Sanctuary (Northwestern Mediterranean
Sea). Ocean and Coastal Management 67:63-74.
Habitat use of seven different species of cetaceans inhabiting the
Pelagos Sanctuary was studied using
18-year summer shipboard surveys data, in an area of approximately
25,000 km2. 2940 sightings were
collected: 1996 striped dolphins, 626 fin whales, 120 Risso's
dolphins, 114 sperm whales, 27 common
bottlenose dolphins, 25 long-finned pilot whales, 23 Cuvier's beaked
whales. Stepwise Logistic Regression
Analysis was used to develop presence/absence predictive models.
Statistics of depth and slope were
used as covariates. Significant correlations were outlined (P < 0.05)
supporting the hypothesis that
physiographic factors may be employed as predictors of the species
presence. The temporal variability of
the species habitat use was also analyzed, confirming the reliability
of the physiographic predictors.
Temporal trends and variability in the species distribution were also
assessed through a GLM analysis.
The understanding offered by this long-term study is essential for
managing the conservation status of
these wide-ranging species.
