Ocean acidification may reduce sea scallop fisheries

Fri, 21 Sep 2018 15:14:35 EDT ~ Each year, fishermen harvest more than $500 million worth of Atlantic sea scallops from the waters off the east coast of the United States. A new model, however, predicts that those fisheries may potentially be in danger. Find out more...

The first predators and their self-repairing teeth

Fri, 21 Sep 2018 11:34:21 EDT ~ The earliest predators appeared on Earth 480 million years ago -- and they even had teeth which were capable of repairing themselves. A team of palaeontologists have been able to discover more about how these organisms were able to grow and regenerate their teeth. Find out more...

Hookworms employ live fast/die young strategy in fur seal pup hosts

Thu, 20 Sep 2018 11:55:40 EDT ~ Hookworms exploit a live fast/die young strategy in their South American fur seal pup hosts. As a result, they often kill their host, rather than finding a happy equilibrium. Scientists are concerned that this type of hookworm infection could eventually pose a risk to critically endangered populations of fur seals. Find out more...

Two fishes a day keep the mantid coming back to prey: The first fishing praying mantis

Thu, 20 Sep 2018 10:21:44 EDT ~ For the first time, a praying mantis is recorded to fish. For five days in a row, an adult male was observed hunting and devouring a total of nine guppies from a pond located in a private roof garden in Karnataka, India. Apart from demonstrating such repetitive behavior, the event is remarkable in the fact that it occurred naturally, without external interference. Find out more...

Pairing zebrafish by personality improves fitness of the species

Thu, 20 Sep 2018 10:21:15 EDT ~ Scientists have challenged the theory of 'love at first sight' after discovering that they can boost the reproductive success of zebrafish by pairing them by personality, rather than appearance. Find out more...

EU Fisheries failures jeopardise sustainability of small fishing communities, researchers argue

Thu, 20 Sep 2018 10:21:10 EDT ~ Traditional artisanal fishing has been harmed by EU fishing policies that favor big businesses and ignores other more sustainable approaches to conserving fish stocks, according to new research. Find out more...

Basking sharks can jump as high and as fast as great whites

Thu, 20 Sep 2018 10:21:05 EDT ~ These gentle giants, which can grow up to 10 m in length, have been recorded jumping out of the water as high and as fast as great white sharks. Marine biologists are unsure why they do this, but have pointed to this phenomenon as evidence of how much we still have to learn about marine life. Find out more...

Climate change modifies the composition of reefs

Thu, 20 Sep 2018 10:11:10 EDT ~ Corals devastated by climate change are being replaced naturally by other species such as gorgonians, which are less efficient in acting as a carbon sink. A study has analyzes for the first time why gorgonians are more resistant than corals to human impacts and global climate change. Find out more...

Oldest-known aquatic reptiles probably spent time on land

Wed, 19 Sep 2018 11:14:57 EDT ~ A comprehensive analysis of Mesosaurus fossils shows that bones from adults share similarities with land-dwelling animals -- suggesting older Mesosaurus were semi-aquatic, whereas the juveniles spent their time in the water. This new research emphasizes the importance of thoroughly analyzing fossilized remains from across all stages of a reptile's life to get a full appreciation of its lifestyle and behavior.

Eelgrass wasting disease has new enemies: Drones and artificial intelligence

Tue, 18 Sep 2018 11:09:56 EDT ~ Every year, the world loses an estimated 7 percent of its seagrasses. While the reasons are manifold, one culprit has long confounded scientists: eelgrass wasting disease. This September a team of biologists is zeroing in on the problem, in the first study of the disease to stretch along the Pacific Coast from southern California to Alaska. Find out more...
