Automated Detection and Classification of Marine Species Vocalizations Using a YOLO‐Based Deep Learning Framework

Ecology and Evolution, Volume 16, Issue 4, April 2026.
This study proposes a YOLO‐inspired deep learning framework to automatically detect and classify marine species vocalizations, using a synthetic dataset to simulate realistic overlapping and non‐overlapping conditions. The model demonstrated strong performance and high precision, establishing a baseline for implementing real‐time passive acoustic ...

Managing Clutter in a High Pulse Rate Echolocation System

Frontiers in Neuroscience, 2018
The use of echolocation for navigating in dense, cluttered environments is a challenge due to the need for rapid sampling of nearby objects in the face of delayed echoes from distant objects.

Correlated evolution between body size and echolocation in bats (order Chiroptera)

BMC Ecology and Evolution
Background Body size and echolocation call frequencies are related in bats. However, it is unclear if this allometry applies to the entire clade. Differences have been suggested between nasal and oral emitting bats, as well as between some taxonomic ...

Echolocation as an Acoustic Form of Relative Positioning [PDF]

TransNav
To introduce order in the movement of many objects, they need to avoid collisions with their neighbours by knowing their position and reacting to it.

DOLPHIN ECHOLOCATION [PDF]

Le Journal de Physique IV, 1992
Latest achievments in understanding of mechanisms underlying dolphin echolocation are discussed. Main attention is drawn to dolphin detection and recognition in different acoustic conditions. Adaptation of echolocation signal parameters to changing ambient noise and reverberation are also considered.

Urbanisation Drives Microevolution in the Egyptian Fruit Bat (Rousettus aegyptiacus)

Evolutionary Applications, Volume 19, Issue 4, April 2026.
ABSTRACT Urbanisation is a pervasive global phenomenon that exerts strong influence on biodiversity and ecosystems. Many species can thrive in urban landscapes by capitalising on generalist traits and environmental resilience; however, this does not safeguard against potential biases exerted by urban environments on population processes.

Seasonal and Diurnal Patterns of Harbor Porpoise (Phocoena phocoena) Behavior and the Disruptive Effects of Vessel Presence in a High‐Traffic Coastal Habitat

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Chronic anthropogenic activity is an ongoing threat to the marine environment and presents unique challenges in shallow, coastal habitats where harbor porpoises reside. Harbor porpoises have high metabolic needs and are highly susceptible to negative environmental factors; however, no long‐term studies have been conducted on wild populations ...

Characterizing the Distribution and Behavior of Sperm Whales, Physeter macrocephalus, Over the Otago Submarine Canyons, New Zealand

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Sperm whales (Physeter macrocephalus) play an important role in marine ecosystems as top predators, nutrient vectors, and indicators of ecosystem health. In Aotearoa New Zealand, sperm whales remain largely understudied other than at Kaikōura, a foraging area for males.

Harbor Porpoises (Phocoena phocoena) in Dublin Bay: How Does Dredge Disposal Affect Foraging Behavior?

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Harbor porpoises (Phocoena phocoena) are among the most widespread cetacean species in Irish waters and are listed under Annex II of the EU Habitats Directive as a species of community importance. The local harbor porpoise population in Dublin Bay coexists with designated spoil grounds for dredging activity, which has increased due to Dublin ...
