Demography of the bottlenose dolphin Tursiops truncatus (Mammalia: Delphinidae) in the Eastern Ligurian Sea (NW Mediterranean): quantification of female reproductive parameters

open access: yesThe European Zoological Journal, 2017
The reproductive histories of 41 adult bottlenose dolphin females were analysed using photo-identification data collected between 2006 and 2014 in four sub-areas of the eastern Ligurian Sea (northwest Mediterranean).

Synchronous and Rhythmic Vocalizations and Correlated Underwater Behavior of Free-ranging Atlantic Spotted Dolphins (Stenella frontalis) and Bottlenose Dolphins (Tursiops truncatus) in the Bahamas

open access: yes, 2015
Since 1985 a resident community of Atlantic spotted dolphins (Stenella frontalis), and bottlenose dolphins (Tursiops truncatus), have been studied underwater in the Bahamas.

Alkenones in oceanic odontocetes as a potential proxy of environmental water temperature

open access: yesEcological Indicators, 2021
The alkenones C37:2 and C37:3 are produced exclusively by some haptophyte species. Their relative proportion (Uk’37 index) may be used to infer the water temperature where the synthesising haptophyte lived.

Evaluating Seasonal vs. Spatial Extrapolation for Cetacean Distribution Models in the California Current

open access: yesMarine Mammal Science, EarlyView.
ABSTRACT Species distribution models (SDMs) have been developed for multiple cetacean species within the California Current Ecosystem (CCE) from shipboard survey data collected by the Southwest Fisheries Science Center (SWFSC) in summer and fall, thus limiting the ability to inform management decisions in cool seasons when abundance and distribution ...

Challenges of collecting blow from small cetaceans

open access: yesEcosphere, 2019
We trialed the collection of blow samples using a waterproof electric multirotor (quadcopter) drone from two free‐ranging dolphin species, the abundant and approachable bottlenose dolphin (Tursiops aduncus) and the less common and boat shy humpback ...

Duration of unassisted swimming activity for spotted dolphin (Stenella attenuata) calves: implications for mother-calf separation during tuna purse-seine sets [PDF]

open access: yes, 2006
Size-related differences in power production and swim speed duration may contribute to the observed deficit of nursing calves in relation to lactating females killed in sets by tuna purse-seiners in the eastern tropical Pacific Ocean (ETP).

Efficient coding in dolphin surface behavioral patterns [PDF]

open access: yes, 2009
We show that the law of brevity, i.e. the tendency of words to shorten as their frequency increases, is also found in dolphin surface behavioral patterns. As far as we know, this is the first evidence of the law in another species, suggesting that coding

Bottlenose Dolphin Hydrodynamics Research

open access: yesJournal of Aquaculture & Marine Biology, 2015
Data collected thus far, including surface photography, and underwater high definition video footage, have provided answers to many initial questions while providing opportunities for further studies, such as, dolphin burst speeds used in catching fast swimming fish and/or avoiding predatory attacks.

Identification of Lactobacillus strains with probiotic features from the bottlenose dolphin (Tursiops truncatus)

open access: yesJournal of Applied Microbiology, 2013
In order to develop complementary health management strategies for marine mammals, we used culture‐based and culture‐independent approaches to identify gastrointestinal lactobacilli of the common bottlenose dolphin, Tursiops truncatus.
