Dear MARMAM subscribers, My co-authors and me are pleased to anounce recent publication: Journal: Aquatic Conservation: Marine and Freshwater Ecosystems Title: The abundance of common bottlenose dolphins (Tursiops truncatus) in the former special marine reserve of the Cres-Lošinj archipelago, Croatia Authors: Pleslić G., Rako Gospić N., Mackelworth P., Wiemann A., Holcer D. and Fortuna C. Abstract: 1. There is a resident common bottlenose dolphin population inhabiting the Kvarnerić area of the northern Adriatic Sea, Croatia. The observed decline in population size between 1995 and 2003 led to the declaration of a part of the Kvarnerić as the Cres-Lošinj Special Marine Reserve (CLSMR) in 2006. Protection lasted three years, before lapsing. 2. A boat based photo-identification study was conducted between 2004 and 2011 with the aim to estimate the number of bottlenose dolphins inhabiting the CLSMR area, investigate the factors influencing their habitat use and explore the possibility that this area is representative of the population for the whole Kvarnerić. 3. Standard mark-recapture methods and Mth estimator of Chao for closed populations were applied. The lowest value was estimated in 2008 (N=112; 95% CI=94-150) and the highest in 2006 (N=310; 95% CI=265-392). The statistically significant inter-annual variability is likely to reflect natural and anthropogenic driven shifts in habitat use rather than actual changes in population size. 4. The average monthly sighting rate was lower in the tourist season (Jun-Aug) compared to pre- and post-season indicating that developed nautical tourism may influence shifts in habitat use. Other potential causes are distribution of prey and fishing effort. 5. Inclusion of data from the rest of the Kvarnerić of the years of 2005 and 2011 did not reveal a significant increase of estimated abundance (2005: z=-0.413, p=0.3398; 2011: z=-1.749, p=0.0401). This indicates that the CLSMR area is representative for the whole Kvarnerić. 6. The number of bottlenose dolphins using the CLSMR area seems to have increased compared to the previous study (1995-2003). This could be due to a shift in habitat use or an increase in population size. However, yearly variations indicate processes causing displacements within the dolphin population home range. Conservation measures aiming at reducing the displacements are proposed.
