Integrating eDNA and Visual Surveys With Ocean Drift Models to Monitor Marine Mammals in Tropical Waters

open access: yesEnvironmental DNA, Volume 7, Issue 5, September–October 2025.
This study evaluates the effectiveness of environmental DNA (eDNA) metabarcoding for monitoring marine mammals in tropical waters around Réunion Island. By combining visual surveys with eDNA sampling and reverse particle drift modeling, we show that eDNA captures local cetacean presence and offers additional spatial insight when integrated with ...

Brucella ceti and Brucellosis in Cetaceans [PDF]

open access: yes, 2012
Since the first case of brucellosis detected in a dolphin aborted fetus, an increasing number of Brucella ceti isolates has been reported in members of the two suborders of cetaceans: Mysticeti and Odontoceti. Serological surveys have shown that cetacean

Forebrain neuroanatomy of the neonatal and juvenile dolphin (T. truncatus & S. coeruloalba)

open access: yesFrontiers in Neuroanatomy, 2015
Knowledge of dolphin functional neuroanatomy mostly derives from post-mortem studies and non-invasive approaches (i.e. magnetic resonance imaging), due to limitations in experimentation on cetaceans.

Geographic variability in the acoustic parameters of striped dolphin's (Stenella coeruleoalba) whistles

open access: yesThe Journal of the Acoustical Society of America, 2013
Geographic variation in the acoustic features of whistles emitted by the striped dolphin (Stenella coeruleoalba) from the Atlantic Ocean (Azores and Canary Islands) and the Mediterranean was investigated. Ten parameters (signal duration, beginning, end, minimum and maximum frequency, the number of inflection points, of steps, of minima and maxima in ...

Organisation and evolution of the major histocompatibility complex class I genes in cetaceans

open access: yesiScience
Summary: A quarter of marine mammals are at risk of extinction, with disease and poor habitat quality contributing to population decline. Investigation of the Major Histocompatibility Complex (MHC) provides insight into species’ capacity to respond to ...
