Tough laws to stop the trade of endangered wildlife ‘not enough’

Western conservation groups are seeking stricter law enforcement to tackle a trade in endangered wildlife, but a researcher warns that this is not a ‘silver bullet’ solution. He highlights the case of the Bali starling, where bringing in tougher laws back-fired — only serving to make the bird more popular among the elite. He highlights how sometimes local people who know the realities on the ground get better results.

Lousy sockeye are lousy competitors

A key discovery has been made regarding Fraser River sockeye’s vulnerability to sea lice. Their recently published research indicates that juvenile Fraser River sockeye salmon that are highly infected with sea lice are 20 percent less successful at consuming food than their lightly infected counterparts.

Species’ evolutionary choice: Disperse or adapt?

Dispersal and adaptation are two evolutionary strategies available to species given an environment. Generalists, like dandelions, send their offspring far and wide. Specialists, like alpine flowers, adapt to the conditions of a particular place. New research models the interplay between these two strategies and shows how even minor changes in an environment can create feedback and trigger dramatic shifts in evolutionary strategy.

How to reset a diseased cell

In proof-of-concept experiments, researchers demonstrate the ability to tune medically relevant cell behaviors by manipulating a key hub in cell communication networks. The manipulation of this communication node makes it possible to reprogram large parts of a cell’s signaling network instead of targeting only a single receptor or cell signaling pathway.
