Dolphins adapt to survive invasive coastal constructions

Marine ecosystems are endangered by an increasing number of coastal development projects. A new study shows for the first time that bottlenose dolphins may adapt to anthropogenic disturbance under some circumstances. The findings draw attention to the need for proper management of coastal construction sites. By Suzanna Burgelman, Frontiers Science writer Social interaction between two bottlenose dolphins. Image: Ann Waver Bottlenose dolphins learn to cope with coastal construction activities. That is the conclusion of a study published in Frontiers in Marine Science. The study is the first to provide a longitudinal perspective on the cumulative impacts of coastal construction. Dolphins adapted to the construction of a bridge by establishing feeding locations outside of the construction zone, and by shifting the timings of behaviors to a time in the day when construction activities were minimized. Coastal development practices negatively impact marine wildlife Marine coastal development is characterized by unsustainable practices. Coastal development exposes 47% of coastal marine mammal species and 51% of core marine mammal habitats to extensive anthropogenic disturbance. Human activities along coastlines and in marine habitats can lead to pollution, vessel strikes, entanglement, by-catch, and debris ingestion, which disturb and harm marine wildlife.

Strange creatures accidentally discovered beneath Antarctica’s ice shelves

Prior research has suggested that the watery depths below the Antarctic ice shelves are too cold and nutrient poor to sustain much life. But a new study from British Antarctic Survey reveals the discovery of a colony of sponges and other animals attached to a boulder on the sea floor – challenging researchers’ understanding about the existence of life in extreme environments.

During an exploratory survey, researchers drilled through 900 meters of ice in the Filchner-Ronne Ice Shelf, situated on the south eastern Weddell Sea. At a distance of 260km away from the open ocean, under complete darkness and with temperatures of -2.2°C, very few animals have ever been observed in these conditions. But this study is the first to discover the existence of stationary animals – similar to sponges and potentially several previously unknown species – attached to a boulder […]
