Data from: Automated peak detection method for behavioral event identification: detecting Balaenoptera musculus and Grampus griseus feeding attemptsDavid A. Sweeney, Stacy L. DeRuiter, Ye Joo McNamara-Oh, Tiago A. Marques, Patricia Arranz & John Calambokidis
The desire of animal behaviorists for more flexible methods of conducting inter-study and inter-specific comparisons and meta-analysis of various animal behaviors compelled us to design an automated, animal behavior peak detection method that is potentially generalizable to a wide variety of data types, animals, and behaviors. We detected the times of feeding attempts by 12 Risso’s dolphins (Grampus griseus) and 36 blue whales (Balaenoptera musculus) using the norm-jerk (rate of change of acceleration) time series....
Many songbird species avoid roads. Although acoustic masking, vehicle collision, and edge effects are likely culprits, spatial avoidance also occurs along low use roads and at locations distant from the pavement. Neophobia may be one factor contributing to avoidance in these regions. In this case, playback of bird song, generally a signal of high-quality habitat, may reduce avoidance and increase territory establishment. We investigated whether playback of song from 6 migratory species increased territory establishment...
Data from: Behavioral responses of individual blue whales (Balaenoptera musculus) to mid-frequency military sonarBrandon L. Southall, Stacy L. DeRuiter, Ari Friedlaender, Alison K. Stimpert, Jeremy A. Goldbogen, Elliott Hazen, Caroline Casey, Selene Fregosi, David E. Cade, Ann N. Allen, Catriona M. Harris, Greg Schorr, David Moretti, Shane Guan & John Calambokidis
This study measured the degree of behavioral responses in blue whales (Balaenoptera musculus) to controlled noise exposure off the southern California coast. High-resolution movement and passive acoustic data were obtained from non-invasive archival tags (n=42) while surface positions were obtained with visual focal follows. Controlled exposure experiments (CEEs) were used to obtain direct behavioral measurements before, during, and after simulated and operational military mid-frequency active sonar (MFAS), pseudorandom noise (PRN), and controls (no noise exposure)....
Cuvier's beaked whales (Ziphius cavirostris) have stranded in association with mid-frequency active sonar (MFAS) use, and though the causative mechanism linking these events remains unclear, it is believed to be behaviourally mediated. To determine whether MFAS use was associated with behavioural changes in this species, satellite tags were used to record the diving and movements of 16 Cuvier's beaked whales for up to 88 days in a region of frequent MFAS training off the coast...
Data from: Northern bottlenose whales in a pristine environment respond strongly to close and distant navy sonar signalsPaul Wensveen, Saana Isojunno, Rune Hansen, Alexander Von Benda-Beckmann, Lars Kleivane, Sander Van IJsselmuide, Frans-Peter Lam, Petter Kvadsheim, Stacy DeRuiter, Charlotte Curé, Tomoko Narazaki, Peter Tyack & Patrick Miller
Impact assessments for sonar operations typically use received sound levels to predict behavioural disturbance in marine mammals. However, there are indications that cetaceans may learn to associate exposures from distant sound sources with lower perceived risk. To investigate the roles of source distance and received level in an area without frequent sonar activity, we conducted multi-scale controlled exposure experiments (n = 3) with 12 northern bottlenose whales near Jan Mayen, Norway. Animals were tagged with...
