Isochrony in barks of Cape fur seal (<i>Arctocephalus pusillus pusillus</i>) pups and adults Open
Animal vocal communication often relies on call sequences. The temporal patterns of such sequences can be adjusted to other callers, follow complex rhythmic structures or exhibit a metronome‐like pattern (i.e., isochronous). How regular ar…

Automatic detection and taxonomic identification of dolphin vocalisations using convolutional neural networks for passive acoustic monitoring Open
A novel framework for acoustic detection and species identification is proposed to aid passive acoustic monitoring studies on the endangered Indian Ocean humpback dolphin (Sousa plumbea) in South African waters. Convolutional Neural Networ…

Automatic Detection and Taxonomic Identification of Dolphin Vocalisations using Convolutional Neural Networks for Passive Acoustic Monitoring Open
A novel framework for evaluating dolphin sound detection and species identification is proposed to aid passive acoustic monitoring studies on the endangered Indian Ocean humpback dolphin (Sousa plumbea) in South African waters. A multi-cla…

Cetacean diversity of the eastern South Atlantic Ocean and Vema Seamount detected during a visual and passive acoustic survey, 2019 Open
Cetaceans in the eastern South Atlantic Ocean are poorly studied. We present results from a 2 week ship-based survey from Cape Town to Vema Seamount (980 km to the west) during October–November 2019, including visual and towed-hydrophone o…

Temporal patterns in Cape fur seal (Arctocephalus pusillus pusillus) mother and pup attraction calls Open
Vocal recognition is widespread in the animal kingdom, and a necessary tool for offspring survival in some groups. Temporal patterns of animal vocalisations can facilitate communication and convey information such as identity, emotional st…

Improving detectability of dolphin signature whistles for capture‐recapture analysis: an examination of array configuration using real‐world data Open
Abundance estimates of cetaceans are often acquired through capture‐recapture analysis of photographically identified individuals. An alternative method, using capture‐recapture of individually distinct signature whistles detected from aco…

Detection of humpback whale (<i>Megaptera novaeangliae</i>) non-song vocalizations around the Vema Seamount, southeast Atlantic Ocean Open
Humpback whales are a cosmopolitan, highly vocal species. Investigated here are their vocalizations recorded at the Vema Seamount (31°38′S, 08°20′E) from moored hydrophones in the austral spring of 2019. During the 11-d recording period ov…

HydroMoth: Testing a prototype low‐cost acoustic recorder for aquatic environments Open
Passive acoustic monitoring (PAM) involves recording the sounds of animals and environments for research and conservation. PAM is used in a range of contexts across terrestrial, marine and freshwater environments. However, financial constr…
