Long‐Term Fluctuations in Cetacean Occurrence Derived From Whale‐Watching Platforms Off Southwest Gran Canaria: Evaluating Their Potential as an Ecological Indicator [PDF]

Ecology and Evolution
Long‐term variability in cetacean detection patterns in oceanic archipelagos remains poorly documented, limiting our understanding of temporal dynamics and their relevance for marine conservation and management. Here, we analysed an 18‐year dataset (2004–

Case report: Sarcocystis speeri, Aspergillus fumigatus, and novel Treponema sp. infections in an adult Atlantic spotted dolphin (Stenella frontalis) [PDF]

Frontiers in Veterinary Science, 2023
A complete postmortem examination, including a computed tomography scan “virtopsy” (virtual necropsy), gross necropsy, cytology, histology, and molecular diagnostics were performed to investigate the cause of death of a deceased adult male Atlantic ...

Mitochondrial diversity and inter-specific phylogeny among dolphins of the genus Stenella in the Southwest Atlantic Ocean. [PDF]

PLoS ONE, 2022
The genus Stenella is comprised of five species occurring in all oceans. Despite its wide distribution, genetic diversity information on these species is still scarce especially in the Southwest Atlantic Ocean.

Exodus! Large-scale displacement and social adjustments of resident Atlantic spotted dolphins (Stenella frontalis) in the Bahamas. [PDF]

PLoS ONE, 2017
Over the last 20 years, significant habitat shifts have been documented in some populations of cetaceans. On Little Bahama Bank (LBB) there are sympatric communities of resident Atlantic spotted dolphins (Stenella frontalis) and bottlenose dolphins ...

Facilitative interspecific interactions in marine vertebrates across scales: from individuals to ecosystems. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Facilitative interspecific interactions (FIIs) confer benefits to at least one participant without detriment to others. Although often less emphasised than antagonistic interactions in ecological studies, this review highlights the significant ecological role of FIIs across biological scales – from individual behaviours to population ...

Cetaceans along the southeastern Brazilian coast: occurrence, distribution and niche inference at local scale [PDF]

PeerJ, 2020
It is deemed important to understand cetacean occurrence and distribution to comprehend their ecological roles. The geographical occurrence of species’ niche can be used to better describe their potential distribution.

Morbillivirus and coronavirus survey in stranded cetaceans, Brazil. [PDF]

PLoS ONE
Since 2010, Guiana dolphin morbillivirus (GDMV; family Paramyxoviridae, genus Morbillivirus, species Morbillivirus ceti, syn. Cetacean morbillivirus) is recognized as the cause of death of multiple cetacean species along the Brazilian coast, including an

Aggressive Behaviors of Adult Male Atlantic Spotted Dolphins: Making Signals Count during Intraspecific and Interspecific Conflicts [PDF]

Animal Behavior and Cognition, 2021
Some species exhibit behavioral plasticity by altering their aggressive behavior based on their opponent. Atlantic spotted dolphins (Stenella frontalis) and bottlenose dolphins (Tursiops truncatus) are two sympatric species resident to the northern ...
