Dear colleagues, the following article has just been published online: Bonizzoni S., Furey N., Pirotta E., Valavanis V.D., Würsig B., Bearzi G. 2013. Fish farming and its appeal to common bottlenose dolphins: modelling habitat use in a Mediterranean embayment. Aquatic Conservation: Marine and Freshwater Ecosystems DOI: 10.1002/aqc.2401. ABSTRACT 1. Common bottlenose dolphins Tursiops truncatus interact with fish farms in the Mediterranean Sea. These interactions were investigated in a Greek bay by incorporating multiple geographic, bathymetric, oceanographic, and anthropogenic variables. 2. Generalized additive modelling (GAMs) and generalized estimation equations (GEEs) were used to describe dolphin presence. Visual surveys were conducted over 2909 km under favourable viewing conditions that included 54 dolphin group follows for 457 km. Sea surface temperature (SST) and chlorophyll-a (Chl-a) data were obtained from remote sensing imagery, and distances to sources of human influences including fish farms, a ferro-nickel plant, and a slag disposal area were calculated within a geographic information system (GIS). 3. Bottlenose dolphins were encountered mainly in the south-eastern portion of the study area, and occurrence was not clearly related to SST and Chl-a, nor the ferro-nickel plant or nearby slag disposal area. 4. Dolphin occurrence generally increased within 20 km of fish farms, with four farms and dolphins displaying a positive relationship, seven no clear relationship, and two a negative one. 5. While it is likely that uneaten food and other detritus attract dolphin prey, individual farms (or clusters of farms) clearly had a different appeal. The proximity of the ferro-nickel plant and slag disposal area to 'attractive' fish farms could compromise dolphin health, but physiological data are unavailable. 6. The modelling of multiple variables allowed for a description of dolphin habitat use and attraction to some fish farms. More such data and analysed in similar manner would be instructive for other areas where marine mammals and fish farms co-occur. http://onlinelibrary.wiley.com/doi/10.1002/aqc.2401/abstract If you are unable to download the article from the journal's site, please send a request to: <silvia.bonizzoni@gmail.com> - - - - - - - Silvia Bonizzoni Dolphin Biology & Conservation http://www.dolphinbiology.org/
