Harbour porpoises (Phocoena phocoena) and wind farms: a case study in the Dutch North Sea [PDF]

, 2011
The rapid increase in development of offshore wind energy in European waters has raised concern for the possible environmental impacts of wind farms. We studied whether harbour porpoise occurrence has been affected by the presence of the Dutch offshore ...

Acoustic Signals and Behavior of the Invasive Freshwater Crayfish Cherax destructor (Clark, 1936)

Journal of Marine Science and Engineering, 2023
The study of acoustic signals in aquatic animals contributes to developing new monitoring systems based on passive acoustics and improves our knowledge of their behaviors and ecology.

Spatio-temporal patterns of beaked whale echolocation signals in the North Pacific. [PDF]

, 2014
At least ten species of beaked whales inhabit the North Pacific, but little is known about their abundance, ecology, and behavior, as they are elusive and difficult to distinguish visually at sea.

Passive acoustic monitoring in ecology and conservation

, 2017
are urgently needed to understand how global change is affecting wildlife and ecosystems. Sound is an important component of any habitat, and sound recordings made in the field offer potentially rich sources of ecological information about the abundance, distribution and behaviour of vocalising animals in an area.

Population size estimation of chirp and grunt generating fish and mammals using cross-correlation based technique with three acoustic sensors

Journal of Ocean Engineering and Science, 2019
Passive acoustic monitoring has the potential to be a useful tool for population estimation of sound-producing fish and mammals (mostly whales).

Community Bioacoustics: Studying Acoustic Community Structure for Ecological and Conservation Insights

Frontiers in Ecology and Evolution, 2021
The diversity of animal acoustic signals has evolved due to multiple ecological processes, both biotic and abiotic. At the level of communities of signaling animals, these processes may lead to diverse outcomes, including partitioning of acoustic signals

Buzzy bees: Improving the monitoring of pollinator activity in sunflower fields with continuous acoustic recording and deep learning

Ecological Informatics
Animal pollination is involved in the reproduction of 90% of flowering plants. Approximately 70% of crops at global scale rely on pollinators, and growing concerns about insect decline highlight the need for effective monitoring of their activity ...

Monitoring the sea environment using acoustics the role of the acoustical observatories [PDF]

, 2013
The presentation deals with theoretical factors and technical specifications pertinent to the design of an acoustical observatory for the monitoring of the marine environment. Two types of observatories are mentioned, namely active and passive. Among the
