Cost-effective conservation helps species bounce back

From Phys.Org | July 8, 2015 Researchers have developed a way to help ecosystems bounce back after human disturbances such as shipping, oil exploration or fishing, and have applied it to a coral reef fish species. The method helps conservation managers create a cost-effective plan to bring species back from the brink of extinction in a local area, by building connections with the same species in nearby locations. “The world is subject to nasty surprises, and this work for the first time …

The role of species competition in biodiversity

By Christopher Packham | July 7, 2015   (Phys.Org)—Over long spans, biodiversity is a fluid and shifting balance of species and influences. Species diversification occurs in response to a host of complex factors, both biotic and abiotic, and understanding them is a major challenge of evolutionary biology. A group of researchers in Sweden, Switzerland and Brazil have collaborated on a study of North American canids to show that competition from multiple carnivore clades is responsible for …

Hard soft coral: New genus and species of ‘living fossil’ octocoral related to blue coral

From Phys.Org | July 2, 2015 Research conducted in Okinawa, Japan, by graduate student Yu Miyazaki and associate professor James Davis Reimer from the University of the Ryukyus has found a very unusual new species of octocoral from a shallow coral reef in Okinawa, Japan. The new species can be considered a “living fossil”, and is related in many ways to the unusual blue coral. The study was published in the open access journal ZooKeys. Unlike scleractinians, most octocorals lack a …

Spiky monsters: New species of ‘super-armored’ worm discovered

From Phys.Org | June 29, 2015   A new species of ‘super-armoured’ worm, a bizarre, spike-covered creature which ate by filtering nutrients out of seawater with its feather-like front legs, has been identified by palaeontologists. The creature, which lived about half a billion years ago, was one of the first animals on Earth to develop armour to protect itself from predators and to use such a specialised mode of feeding. The creature, belonging to a poorly understood group of …
