The Foe You Know: Observations of Interspecific Interactions Between Small Cetaceans and Northern Resident Killer Whales (Orcinus orca) in the Northeast Pacific [PDF]

open access: yesEcology and Evolution
We documented the first aerial observations of interspecific interactions of fish‐eating, northern resident killer whales (Orcinus orca) with two small cetacean species, Dall's porpoises (Phocoenoides dalli) and Pacific white‐sided dolphins ...

Concern for Highly Pathogenic Avian Influenza Spillover into Cetaceans [PDF]

open access: yesViruses
Influenza A virus (IAV) has a wide range of avian and mammalian hosts, leading to disease outbreaks and increasing the risk of panzootics and pandemics.

Spatial Dynamics of Harbour Porpoise Phocoena phocoena Relative to Local Hydrodynamics and Environmental Conditions [PDF]

open access: yesEcology and Evolution
Understanding the spatial dynamics of harbour porpoise (Phocoena phocoena) is crucial for effective conservation and management. The study presents a multidisciplinary approach to modelling and analysing the site occurrence and habitat use of Phocoena ...

Complete Mitochondrial Genome Analysis Reveals Genetic Diversity in the Narrow–Ridged Finless Porpoise (Neophocaena asiaeorientalis) Across East Asian Waters [PDF]

open access: yesEcology and Evolution
The narrow‐ridged finless porpoise (Neophocaena asiaeorientalis Pilleri & Gihr 1972) is one of the most endangered cetacean species inhabiting East Asian waters.

Performance of theodolites versus drones in land-based studies of marine mammals [PDF]

open access: yesScientific Reports
Theodolites and drones are key instruments for observing small whales in coastal areas. This study compared their performance while observing the harbour porpoise (Phocoena phocoena) in the western Baltic Sea.

Temporal and spatial biosonar activity of the recently established uppermost Yangtze finless porpoise population downstream of the Gezhouba Dam: Correlation with hydropower cascade development, shipping, hydrological regime, and light intensity [PDF]

open access: yesEcology and Evolution
Numerous dams disrupt freshwater animals. The uppermost population of the critically endangered Yangtze finless porpoise has been newly formed below the Gezhouba Dam, however, information regarding the local porpoise is scarce.

A shortfin mako shark circling a finless porpoise with damaged caudal fin [PDF]

open access: yesEcology and Evolution
Research on predator–prey interactions between sharks and cetaceans remain limited. Here, we report on a video of a shortfin mako shark circling a finless porpoise with a damaged caudal fin in the Seto Inland Sea, Japan.

A matter of scale: Identifying the best spatial and temporal scale of environmental variables to model the distribution of a small cetacean [PDF]

open access: yesEcology and Evolution
The importance of scale when investigating ecological patterns and processes is recognised across many species. In marine ecosystems, the processes that drive species distribution have a hierarchical structure over multiple nested spatial and temporal ...

Harbour Porpoise Abundance in Portugal over a 5-Year Period and Estimates of Potential Distribution

open access: yesAnimals, 2022
The Iberian porpoise population is small and under potentially unsustainable removal by fisheries bycatch. Recently, a marine Site of Community Importance (SCI) was legally approved in Portugal, but no measures ensued to promote porpoise conservation ...

Out of Sight, Out of Mind: How Conservation Is Failing European Porpoises

open access: yesFrontiers in Marine Science, 2021
The conservation of harbor porpoises (Phocoena phocoena) appears to be failing in Europe. There are particular concerns about this species in the Baltic Proper, Black, and Mediterranean Seas, as well as in the Northeast Atlantic, including the Iberian ...
