Proactive conservation of New Zealand blue whales - Researchers have developed a method for forecasting the locations where a distinct population of New Zealand blue whales are most likely to occur up to three weeks in advance.
‘Whoop’ – new autonomous method precisely detects endangered whale vocalizations - One of the frequently used methods to monitor endangered whales is called passive acoustics technology, which doesn't always perform well. In the increasingly noisy ocean, current methods can mistake other sounds for whale calls. This high 'false positive' rate hampers scientific research and hinders conservation efforts. Researchers used artificial intelligence and machine learning methods to develop a new and much more accurate method of detecting Right whale up-calls -- a short 'whoop' sound that lasts about two seconds.
Warming Atlantic drives right whales towards extinction - Warming oceans have driven the critically endangered North Atlantic right whale population from its traditional and protected habitat, exposing the animals to more lethal ship strikes, disastrous commercial fishing entanglements and greatly reduced calving rates. Without improving its management, the right whale populations will decline and potentially become extinct in the coming decades, according to a recent report.
Study shows a whale of a difference between songs of birds and humpbacks - These findings challenge the results of past studies that vocal variations in humpback whale songs provide information about a singer's reproductive fitness. Instead, the morphing appears to reveal the precise locations and movements of singers from long distances and may enhance the effectiveness of song parts as sonar signals.
Development and evolution of dolphin, whale blowholes - New research is shedding light on how the nasal passage of dolphins and whales shifts during embryonic development from emerging at the tip of the snout to emerging at the top of the head as a blowhole. The findings are an integrative model for this developmental transition for cetaceans.
