Comparative histopathologic and viral immunohistochemical studies on CeMV infection among Western Mediterranean, Northeast-Central, and Southwestern Atlantic cetaceans.

PLoS ONE, 2019
Cetacean morbillivirus (CeMV) is a major natural cause of morbidity and mortality in cetaceans worldwide and results in epidemic and endemic fatalities. The pathogenesis of CeMV has not been fully elucidated, and questions remain regarding tissue tropism

Marine trophic architecture and hidden ecological connections in the Strait of Magellan: keystone species and ecosystem resilience

Oikos, EarlyView.
Understanding the ecological implications of species coexistence is central to biodiversity studies and to identify environmental and anthropogenic drivers of ecosystem dynamics, where ecological network analysis offers valuable insights. This study examines the complexity, structure, and potential responses to disturbances of the Strait of Magellan's ...

Temporal changes in the dietary niche of sympatric seals provides insight into the role of competition in population declines

Oikos, EarlyView.
Competition theory suggests that interspecific prey competition can result in changes to the dietary niche, but obtaining timeseries of data from sympatric species experiencing temporal variation in competition is challenging. Scotland is an important area for two species of seals, but over the past 20 years, populations of harbour seals Phoca vitulina

Developing ocean literacy through a relational model: Exploring outcomes of a place‐based ocean education programme in primary schools

People and Nature, EarlyView.
Abstract Schools are a common place where the younger generation can develop their understanding of the ocean and acquire the skills needed to become responsible and knowledgeable ocean advocates. Grounded in a relational ocean literacy model, this study examined outcomes of a place‐based programme integrating picture books, beach excursions and ...

The ability of artisanal fishers to recognize the dolphins they cooperate with

Journal of Ethnobiology and Ethnomedicine, 2020
Background Human-animal interactions with mutual benefits in the wild are rare. Such positive interactions seem to require an intricate knowledge from the human side on the animals’ behavior and their habitat.

Using a social‐ecological macrosystems framework to understand how human activities alter ecological synchrony

People and Nature, EarlyView.
Abstract Different aspects of ecological systems, biotic or abiotic, often fluctuate in coordinated patterns over space and time. Such high concordance between ecological processes is often referred to as ecological synchrony. Human activities, including and beyond climate change, have the potential to alter ecological synchrony by disrupting or ...

Long-term trends of epibionts reflect Mediterranean striped dolphin abundance shifts caused by morbillivirus epidemics. [PDF]

J Anim Ecol
This original research piece demonstrates, through empirical and theoretical modelling approaches, that the epibionts of striped dolphins indicate dolphin abundance shifts caused by epidemics of dolphin morbillivirus (DMV). In addition, we provide the first SIR model to investigate the epidemiology of DMV in western Mediterranean striped dolphins ...

A new perspective on cancer treatment: the interaction and application prospect between ICIs and radiotherapy

Precision Radiation Oncology, EarlyView.
The combination of immune checkpoint inhibitors (ICIs) and radiotherapy synergistically enhances efficacy through an “antigen release‐immune activation” closed‐loop mechanism, significantly improving outcomes in solid tumors (e.g., lung cancer, melanoma).

Standardization of Dolphin Cardiac Auscultation and Characterization of Heart Murmurs in Managed and Free-Ranging Bottlenose Dolphins (Tursiops truncatus)

Frontiers in Veterinary Science, 2020
Cardiac auscultation is an important, albeit underutilized tool in aquatic animal medicine due to the many challenges associated with in-water examinations.
