Diets of Three Sympatric Grebe Species in Lake Titicaca Indicate Possible Dietary Niche Partitioning

Ecology and Evolution, Volume 15, Issue 10, October 2025.
Lake Titicaca is home to three grebe species whose diets have not been thoroughly studied. In this natural history note, we provide the first description of the diets of these species and how they overlap and differentiate. ABSTRACT Dietary niche partitioning is a fundamental process in community ecology, of interest to both conservationists and ...

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

iScience
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 ...

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

Frontiers 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.

Cetacean Morbillivirus-Associated Pathology: Knowns and Unknowns

Frontiers in Microbiology, 2016
The present minireview deals with the pathology of Cetacean Morbillivirus (CeMV) infection in free-ranging cetaceans. In this respect, while classical CeMV-associated lesions were observed in the lung, brain and lymphoid tissues from striped dolphins ...

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

The 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 ...

Amphiatlantic Dolphins’ Prey: Indicators of Speciation, Trophic Competition and Global Warming? A Review

Journal of Marine Science and Engineering
A review of the prey of three amphiatlantic dolphin species, Tursiops truncatus, Stenella coeruleoalba and Delphinus delphis, is carried out. The main objective of this work is to review the feeding of these species in the Atlantic in order to assess the

Effect of tissue decomposition on stable isotope signatures of striped dolphins Stenella coeruleoalba and loggerhead sea turtles Caretta caretta

Aquatic Biology, 2013
Marine mammals and turtles are often studied using the carcasses of stranded dead individuals. Since decomposition processes might modify the stable isotope ratios of tissues, the present study tested the effects of decomposition on carbon (Δsup>13C) and

P41 | INVOLVEMENT OF THE DOLPHIN’S MELON IN IMMUNE FUNCTION

European Journal of Histochemistry
The striped dolphin (Stenella coeruleoalba) is a small pelagic dolphin. The melon, present in most odontocetes, is a rounded structure located in the center of the forehead, between the blowhole and the tip of the head.
