Maximizing eDNA detections of rare marine organisms: A case study of a delphinid species

Methods in Ecology and Evolution, EarlyView.
Abstract Environmental DNA (eDNA) is an emerging tool for surveying marine organisms. Advances in molecular assay designs and bioinformatic methods provide new opportunities for detecting rare species; however, overcoming methodological challenges of rare species detection remains an important obstacle for the widespread deployment of eDNA methods for ...

The first record of a piebald common bottlenose dolphin (Tursiops truncatus) in offshore waters of the north-western Black Sea

Theriologia Ukrainica, 2020
Piebaldism is one of three types of hypopigmentation of animals, when some areas on the skin have no pigments. Anomalously white cetaceans are rare, although they have been reported in more than 20 different cetacean species, including the common ...

As‐Rigid‐As‐Possible Regularization for Implicit Surfaces

Computer Graphics Forum, EarlyView.
Abstract Implicit surface representations have regained popularity because of their use in machine learning. A common component in optimization is regularization, penalizing the deviation of the surface from its original shape. The popular as‐rigid‐as‐possible (Arap) energy strikes a good compromise between realistic deformation behavior and efficient ...

Prospects of multipurpose biomonitoring for fisheries assessment based on environmental nucleic acids

Journal of Fish Biology, EarlyView.
Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.

The heart responds to pressure via the lung: Dive depth alters cardiac control in bottlenose dolphins

The Journal of Physiology, EarlyView.
Abstract figure legend Dive depth independently modulated cardiac regulation in bottlenose dolphins during controlled voluntary dives. Dolphins performed dives to 0.5, 5 and 10 m with standardized dive durations, allowing the effects of depth on cardiovascular responses to be evaluated.

Vocalization behaviors in captive bottlenose dolphins (Tursiops truncatus) and rough-toothed dolphins (Steno bredanensis).

PLoS ONE
Odontocetes rely on vocalizations for navigation, foraging, and communication. Their vocalization patterns are associated with environmental conditions and behavioral contexts, particularly in captive populations. This study investigated the vocalization

Structural Variation in Whistle Patterns of Two Coastal Dolphin Species Co‐Occurring in the Southern Israeli Mediterranean Sea

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Two coastal dolphin species, the common bottlenose dolphin (Tursiops truncatus—Tt) and the short‐beaked common dolphin (Delphinus delphis—Dd), co‐occur along the southern Israeli Mediterranean coast, where the critically endangered Dd population faces ecological pressures, potentially including competitive exclusion by that of the Tt ...

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.
