Abstract A first attempt at analysing interactions between bottlenose dolphins and gillnets along the northeastern coast of Sardinia (Italy) was conducted October 1999 December 2004. new approach used: combining interviews with fishers boat-based direct observations behavioural group size analysis. Fishers on monitored boats noted 2556 days which gillnet damage caused by dolphins, 68.7% total fishing days, no difference seasons. An annual estimate number caught in 1.47 (0.98 immatures 0.49...
Abstract Identifying foraging variation within a population and assessing its relationship with social structure is essential to increase knowledge about the evolution of systems. Here, we investigated individual in bottlenose dolphins potential influence on their organization. We used generalized affiliation indices applied network analysis data collected over four consecutive years research coastal area subject significant use pressure by humans. Our findings revealed behavior among...
We investigated the presence and diversity of cetaceans in Mediterranean Sea, analysing data collected by 32 different research units, over a period 15 years (2004–2018), shared on common web-GIS platform named Intercet. used encounter rate, species prevalence, Shannon index as parameters for analysis. The results show that cetacean diversity, context basin, is generally quite low when compared with eastern Atlantic, few species, namely striped dolphin, bottlenose fin whale, sperm dominate...
The common bottlenose dolphin is a cosmopolitan species that can be found worldwide in all oceans except polar and sub-polar waters. This wide distribution associated with certain level of morphological variation, which seems consistent the presence globally distributed pelagic/offshore ecotype several coastal/inshore ecotypes along continental shelf. In Mediterranean Sea, regularly occurring second most sighted cetacean after striped dolphin. According to some studies, more closely related...
On the north-eastern coast of Sardinia, from November 2004 to January 2006, first attempt in Mediterranean basin obtain information on encounter rate, group size and incidental capture bottlenose dolphins a marine fish farm was assessed, combining direct observations boats with photo-identification studies. During 15 months research, 79 d (65.3% total monitored days) were spent observation 146 groups around cages. There peak dolphin presence during winter. Photographs taken area encounters...
This paper reports on the results of underwater observations bottlenose dolphin feeding behaviour in a marine fin fish farm Sardinian coast Italy from 2000 to 2005. During study period, 178 encounters were noted during 79 sightings dolphins at farm. Total time spent presence was 284 min, with mean encounter duration 1.6 ± 1.3 min. Bottlenose primarily observed hunting both schooling and solitary prey around cages, using seven cooperative individual strategies throughout water column. The...
Abstract In the coastal environment, marine mammals are exposed to one of fastest growing food production sectors; namely, shellfish farming industry. Identification critical habitats, such as foraging grounds in highly human‐impacted areas, is essential species conservation. Therefore, understanding variables that influence a species' behaviour important for their conservation, especially long‐lived cetaceans. The aims this study were (a) identify and quantify environmental anthropogenic...
Infanticide is considered a conspicuous expression of sexual conflict amongst mammals, including bottlenose dolphins. Although reported previously in this species, confirmed cases infanticide and associated epimeletic behaviour are very rare their socio-behavioural context remains poorly understood. Here, we provide evidence behaviours free-ranging dolphins Galicia, NW Spain. After describing the observed events, include complete description post-mortem examinations (where carcasses were...
The expansion of fisheries and its increased efficiency are causing severe detrimental impacts on marine species ecosystems, that can be categorised into operational ecological effects. While directly caused by fishing activities have been extensively documented, it is difficult to set an empirical link between changes in predator biomass abundance. Therefore, exploring the functioning ecosystems as a whole, interactions different within them impact human activities, key understanding...
This study presents the first robust estimates of abundance and demographic parameters common bottlenose dolphins (Tursiops truncatus) in a highly affected coastal ecosystem along north-eastern Atlantic. Seasonal abundance, apparent survival temporary emigration rates were estimated using Pollock’s design models. Photographic identification data collected from 2014 to 2016 north-western Iberian coast (Spain). Bottlenose present year-round with high degree occurrence area, which is by human...
