This preliminary study of whales and dolphins off the French Mediterranean coasts refers to 15 spp, 11 Odontoceti and 4 Mysticeti: 3 of them are common; Delphinus delphis, Tursiops truncatus and Ziphius cavirostris (in the Ligurian sea), 2 are frequent in the Ligurian sea: Grampus griseus and Balaenoptera physalus, 3 are not uncommon: Stenella coeruleoalba, Globicephala melaena, and Physeter macrocephalus, 2 are rare: Pseudorca crassidens and Orcinus orca, 3 are exceptional: Balaena acutorostrata, Megaptera novaeangliae, and Steno bredanensis, 2 seem doubtful: Hyperoodon ampullatus and Balaenoptera musculus. Also important is the fact that no Phocoena phocoena has been observed. More generally, whales and dolphins seem to be more abundant in the area... |

Whale strandings convey a great deal of information on the complex factors that affect the survival of cetacean species. International law protects cetaceans, and governments have committed themselves to conserve populations, to support research and to organise the scientific response to stranding events. In Belgium, a number of research units, public services and volunteers have been organized into an intervention network to deal with stranded animals. The practical difficulties are many and can only be overcome through good co-ordination, rapid response and full co-operation of experts in various fields. Though much progress has been achieved in the right direction, many problems remain to be solved. As was made obvious with the stranding of four sperm... |

Tourism development can have positive and/or negative impacts on wildlife. However, if tourism is developed in accordance with the basic tenets of wildlife tourism such an activity can be sustainable and can aid the conservation of species. Based on two case studies in Queensland, Australia, this article outlines the various economic and conservation benefits arising from wildlife-based tourism. Some of the benefits are direct, such as tangible economic benefits, others are less tangible, such as increased visitors’ willingness to pay in principle for the conservation of species. Wildlife-based tourism is shown to foster political support for the conservation of species utilized for such tourism by various mechanisms. Non-consumptive uses of wildlife are... |

The effects of "localized depletion" of a pelagic fishery (herring) on a non-extractive marine activity (tourism) are investigated. Proponents of the localized depletion theory claim that intense fishing effort can lead to areas that are unsuitable for predators like tuna, groundfish, and whales. This leads to poor outcomes for the fishing and whale-watching industries. However, there has been no consensus in the scientific community about the existence of this phenomenon. Localized depletion would be consistent with an economic theory of joint production, in which nearshore herring stocks are an input in production of both herring and whale-watching trips. A unique dataset of daily whale-watching outcomes is combined with fishing effort and oceanographic... |
