Seal Bomb Noise as a Potential Threat to Monterey Bay Harbor Porpoise

Frontiers in Marine Science, 2020
Anthropogenic noise is a known threat to marine mammals. Decades of research have shown that harbor porpoises are particularly sensitive to anthropogenic noise, and geographic displacement is a common impact from noise exposure.

Programmed unmanned aerial vehicles show great potential for monitoring marine megafauna in specific areas of interest

Remote Sensing in Ecology and Conservation, Volume 12, Issue 3, Page 368-387, June 2026.
Targeted conservation measures are contingent on robust knowledge of spatio‐temporal animal distribution in areas of interest. We explore unmanned aerial vehicle (UAV) transect monitoring as a novel method for standardized digital aerial surveys of marine megafauna by investigating the fine‐resolution spatio‐temporal distribution of harbour porpoises ...

Local ecological knowledge and the interaction of porpoises with fishing on the coast of the state of Para, Brazil [PDF]

Biotemas, 2012
Fishing has a great importance to the socioeconomic development of the Amazonian riparian communities, which have a local knowledge on the environment, its fauna and flora.

The Influence of Sea Ice and Ice Mélange on Outlet Glacier Dynamics in the Arctic and Antarctic: Recent Progress and Future Challenges

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Sea ice is situated close to the termini of many outlet glaciers in the Arctic and Antarctic and has the potential to influence their dynamics and, therefore, their contribution to sea level rise. However, the nature, prevalence, and ice‐dynamic significance of sea ice‐glacier interactions remains subject to several open questions.

Whole Genome Analyses of the Endangered Northern Abalone (Haliotis kamtschatkana) Reveal Population Differentiation and a Genomic Signature of a Dramatic Population Decline

Evolutionary Applications, Volume 19, Issue 6, June 2026.
ABSTRACT Despite widespread declines of many wildlife species, the effects of population decline on the genome and the recovery potential of affected species are still poorly understood, especially beyond a few charismatic species. The Northern abalone (or Pinto abalone; Haliotis kamtschatkana) is a marine gastropod mollusk of social, cultural and ...

The Importance of Individual Body Condition in Mammalian Behavioural Responses to Disturbance

Mammal Review, Volume 56, Issue 2, June 2026.
Body condition, shaped by the balance between energy demands and reserves, predictably shapes mammalian disturbance responses. Poor‐condition individuals adopt needs‐based strategies, accepting greater risks to meet immediate energetic needs, while good‐condition individuals follow asset‐protection strategies, minimizing risks to protect their survival

The harbour porpoise (Phocoena phocoena) in the North Atlantic: Variability in habitat use, trophic ecology and contaminant exposure

NAMMCO Scientific Publications, 2003
Harbour porpoises inhabit coastal waters, in habitats that are characterized by high diversity and complexity in terms of their bathymetry, substrate, fish communities and point sources of contaminants.

Whole‐Genome‐Sequencing Reveals Demographic History and Patterns of Parallel Adaptive Evolution in Indo‐Pacific Bottlenose Dolphins (Tursiops aduncus) Across Coastal Australian Seascapes

Molecular Ecology, Volume 35, Issue 11, June 2026.
ABSTRACT Understanding how demographic dynamics interact with environmental heterogeneity is central to explaining patterns of genomic variation in the marine realm. Indo‐Pacific bottlenose dolphins (Tursiops aduncus) occur along most of the Australian coastline, from tropical to temperate waters, encompassing pronounced differences in temperature ...

Long-term effectiveness of pingers on a small population of finless porpoises in Japan

Endangered Species Research, 2017
Finless porpoises Neophocaena spp. are under pressure from various anthropogenic impacts due to their coastal habitat. Net fishery bycatch is considered a major risk for the populations around Japan, and mitigation measures are required. We carried out a
