White or Blue, the Whale gets its Vengeance: A Social Media Analysis of the Blue Whale Challenge
The Blue Whale Challenge is a series of self-harm causing tasks that are propagated via online social media under the disguise of a “game.”The list of tasks must be completed in a duration of 50 days and they cause both physical and mental harm to the player. The final task is to commit suicide. The game is supposed to be administered by people called “curators ”who incite others to cause self-...
متن کاملBlue whale earplug reveals lifetime contaminant exposure and hormone profiles.
Lifetime contaminant and hormonal profiles have been reconstructed for an individual male blue whale (Balaenoptera musculus, Linnaeus 1758) using the earplug as a natural aging matrix that is also capable of archiving and preserving lipophilic compounds. These unprecedented lifetime profiles (i.e., birth to death) were reconstructed with a 6-mo resolution for a wide range of analytes including ...
متن کاملExposure to seismic survey alters blue whale acoustic communication.
The ability to perceive biologically important sounds is critical to marine mammals, and acoustic disturbance through human-generated noise can interfere with their natural functions. Sounds from seismic surveys are intense and have peak frequency bands overlapping those used by baleen whales, but evidence of interference with baleen whale acoustic communication is sparse. Here we investigated ...
متن کاملFrequency synchronization of blue whale calls near Pioneer Seamount.
Vocalizations of blue whales were recorded with a cabled hydrophone array at Pioneer Seamount, 50 miles off the California coast. Most calls occurred in repeated sequences of two-call pairs (A, then B). The B call is a frequency-modulated tone highly repeatable in form and pitch. A model of this sound is described which permits detecting very small frequency shifts. B calls are found to be alig...
متن کاملFine-Scale Population Structure of Blue Whale Wintering Aggregations in the Gulf of California
Population differentiation in environments without well-defined geographical barriers represents a challenge for wildlife management. Based on a comprehensive database of individual sighting records (1988-2009) of blue whales from the winter/calving Gulf of California, we assessed the fine-scale genetic and spatial structure of the population using individual-based approaches. Skin samples of 1...
