Nontargeted biomonitoring of halogenated organic compounds in two ecotypes of bottlenose dolphins (Tursiops truncatus) from the Southern California Bight. [PDF]

open access: yes, 2015
Targeted environmental monitoring reveals contamination by known chemicals, but may exclude potentially pervasive but unknown compounds. Marine mammals are sentinels of persistent and bioaccumulative contaminants due to their longevity and high trophic ...

Decades-long social memory in bottlenose dolphins [PDF]

open access: yesProceedings of the Royal Society B: Biological Sciences, 2013
Long-term social memory is important, because it is an ecologically relevant test of cognitive capacity, it helps us understand which social relationships are remembered and it relates two seemingly disparate disciplines: cognition and sociality. For dolphins, long-term memory for conspecifics could help assess social threats as well as potential ...

High genetic structure and low mitochondrial diversity in bottlenose dolphins of the Archipelago of Bocas del Toro, Panama: A population at risk?

open access: yesPLoS ONE, 2017
The current conservation status of the bottlenose dolphin (Tursiops truncatus) under the IUCN is 'least concern'. However, in the Caribbean, small and localized populations of the 'inshore form' may be at higher risk of extinction than the 'worldwide ...

Model-Based Method for Social Network Clustering

open access: yes, 2018
We propose a simple mixed membership model for social network clustering in this note. A flexible function is adopted to measure affinities among a set of entities in a social network.

Abundance and behavioural ecology of bottlenose dolphins (Tursiops truncatus) in the Marlborough Sounds, New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Conservation Biology at Massey University [PDF]

open access: yes, 2007
In order to survive, animals require both food and protection from predators. These ecological factors are major determinants in habitat selection and social interactions.

Habitat preferences among three top predators inhabiting a degraded ecosystem, the Black Sea

open access: yesScientia Marina, 2017
This study investigated whether there is evidence of widespread niche partitioning based on environmental factors in the Black Sea and tested the hypothesis that physiographic factors may be employed as predictors.

Bi-Objective Community Detection (BOCD) in Networks using Genetic Algorithm

open access: yes, 2011
A lot of research effort has been put into community detection from all corners of academic interest such as physics, mathematics and computer science. In this paper I have proposed a Bi-Objective Genetic Algorithm for community detection which maximizes

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).

Transatlantic Surveys of Seabirds, Cetaceans and Turtles, July 2013 and July 2018 [PDF]

open access: yes, 2018
Analysis of multi-species tracking data suggest that an area of the deep northwest Atlantic bounded by Flemish Cap, Charlie-Gibbs Fracture Zone and Mid-Atlantic Ridge (MAR) has a relatively high abundance and diversity of pelagic seabirds.

Dolphin-inspired target detection for sonar and radar

open access: yes, 2014
Gas bubbles in the ocean are produced by breaking waves, rainfall, methane seeps, exsolution, and a range of biological processes including decomposition, photosynthesis, respiration and digestion.
