Published Feathered 'fingerprints' reveal potential motivation for migratory patterns of endangered seabirds
(via sciencedaily.com) New research shows that the feathers of seabirds such as the Wandering Albatross can provide clues about their long-distance foraging, which could help protect these species from further decline.
Published Whales give up singing to fight for love
(via sciencedaily.com) Male whales along Australia's eastern seaboard are giving up singing to attract a mate, switching instead to fighting their male competition.
Published How the fastest fish hunts its prey
(via sciencedaily.com) Scientists have designed a novel electronic tag package incorporating high-tech sensors and a video camera in order to document a detailed view of exactly how sailfish behave and hunt once they are on their own and out of view of the surface.
Published Whale warning as clock ticks towards deep-sea mining
(via sciencedaily.com) Seabed mining could soon begin in the deep ocean -- but the potential impact on animals including whales is unknown, researchers have warned.
Published Coral reefs in the Eastern Pacific could survive into the 2060s
(via sciencedaily.com) Scientists found that some reefs in the tropical Pacific Ocean could maintain high coral cover into the second half of this century by shuffling the symbiotic algae they host. The findings offer a ray of hope in an often-dire picture of the future of coral reefs worldwide.
Published Biodiversity engine for fishes: Shifting water depth
(via sciencedaily.com) Fish, the most biodiverse vertebrates in the animal kingdom, present evolutionary biologists a conundrum: The greatest species richness is found in the world's tropical waters, yet the fish groups that generate new species most rapidly inhabit colder climates at higher latitudes. A new study helps to explain this paradox. The researchers discovered that the ability of fish in temperate and polar ecosystems to transition back and forth from shallow to deep water triggers species diversification. Their findings suggest that as climate change warms the oceans at higher latitudes, it will impede the evolution of fish species.
Published Due to their feed, chicken and farmed salmon have remarkably similar environmental footprints
(via sciencedaily.com) We love our chicken. We love our salmon. Thanks to how we farm these two popular proteins, their environmental footprints are surprisingly similar.
Published 'It's me!' Fish recognizes itself in photographs, say scientists
(via sciencedaily.com) Original source Scientists have demonstrated that fish think 'it's me' when they see themselves in a picture. The researchers found that the determining factor was not the fish seeing their own body but seeing their face.
Published Fossil discovery reveals complex ecosystems existed on Earth much earlier than previously thought
(via sciencedaily.com) Original source About 250 million years ago, the Permian-Triassic mass extinction killed over 80 per cent of the planet's species. In the aftermath, scientists believe that life on earth was dominated by simple species for up to 10 million years before more complex ecosystems could evolve. Now this longstanding theory is being challenged by a team of international researchers.
Published The cod population off the coast of Sweden is not extinct
(via sciencedaily.com) Original source Through DNA analyses, researchers have identified that there are still juvenile coastal cod off the west coast of Sweden. However, it is still difficult to find any mature adult cod in the area.
Published Marine reserves unlikely to restore marine ecosystems
(via sciencedaily.com) Protected marine areas are one of the essential tools for the conservation of natural resources affected by human impact -- mainly fishing --, but, are they enough to recover the functioning of these systems? A study now highlights the limitations of marine reserves in restoring food webs to their pristine state prior to the impact of intensive fishing.
Published Surprises in sea turtle genes could help them adapt to a rapidly changing world
(via sciencedaily.com) Around 100 million years ago, a group of land-dwelling turtles took to the oceans, eventually evolving into the sea turtles that we know today. However, the genetic foundations that have enabled them to thrive in oceans throughout the world have remained largely unknown.
