Conceptive Estrus Behavior in Three Bottlenose Dolphins (Tursiops truncatus) [PDF]

Animal Behavior and Cognition, 2015
Bottlenose dolphins (Tursiops truncatus) are a highly promiscuous species that routinely engage in socio-sexual interactions, yet relatively little has been reported about actual estrus behavior.

Group‐Specific Variation in Heterodyne Frequencies of Biphonic Calls in Resident (R‐Type) Killer Whales Orcinus orca ater

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Biphonation—the simultaneous production of two independent fundamental frequencies within a single vocalization—is a prominent feature of killer whale calls, yet the factors influencing the presence and intensity of heterodyne frequencies, which arise from interactions between these fundamentals, remain poorly understood. We analyzed long‐term

Genetic Identification and Population Assignment of Extralimital Sightings of Hector's Dolphins

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 8, August 2026.
ABSTRACT Genetic identification from extralimital sightings can determine whether an individual comes from a small or large population, with conservation implications. Such is the case for the endangered Hector's and critically endangered Māui dolphins of Aotearoa/New Zealand. We compare the success of three opportunistic sampling methodologies (biopsy,

Enhancing Intra‐Specific Population Genetic Studies of Bottlenose Dolphins (Tursiops truncatus) in Irish Waters by Integrating Least Invasive Sampling and Environmental DNA (eDNA)

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Three populations of bottlenose dolphins are found in Irish waters. This study used direct sampling methods to expand the sample size and confirm the distinctiveness of these populations, including a range expansion outside of the Shannon Estuary SAC.

Is Blood Thicker Than Water? The Influence of Kin Within a Bull Shark Social Network

Ecology and Evolution, Volume 16, Issue 8, August 2026.
This study investigates how kinship (“kinfluence”) shapes social structure in an aggregation of adult bull sharks in Fiji by integrating genomic relatedness, pedigree reconstruction, and detailed behavioral data. It reveals that while genetic relatedness has a small but significant influence on social behavior, especially among males, kin‐category ...

Blindfolded Imitation in a Bottlenose Dolphin ( Tursiops truncatus )

International Journal of Comparative Psychology, 2010
This study investigated the ability of a bottlenose dolphin to adapt a previously learned "do-as-I-do"procedure to copy behaviors of another dolphin while blindfolded (i.e., wearing eyecups). In Experiment 1, the dolphin was able to copy both vocal and motor behaviors, whether blindfolded or sighted.

Yulendji Bunwurrung Walagunh With Western Science: Ecological Insights, Emerging Research Questions and Future Directions From Bunurong Stories of Marine Mammals

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Indigenous Knowledge systems contain deep, place‐based ecological insights developed over generations but remain underrepresented in biodiversity assessments and conservation planning. This study explores yulendji Bunwurrung (Bunurong knowledge) through five Stories shared by a Bunurong Elder, using thematic analysis and comparison with contemporary ...
