Imitation is the most sincere form of flattery — especially in the predator/prey/poison cycle. In nature, bright colors are basically neon signs that scream, ‘Don’t eat me!’ But how did prey evolve these characteristics? When did predators translate the meaning?

Does haze from burning forests affect marine life?
Two scientists are calling on researchers, NGOs, and governments to begin studying the impact of burning forests and peatlands in Indonesia on the already-threatened marine ecosystems of Southeast Asia. Every year, Indonesian farmers set forests, vegetation, and peatlands alight to clear them for agriculture, often palm oil, and pulp and paper plantations. Not only do […]
Protecting species in Canada
Of 345 species at risk in Canada, more than 160 have waited far too long for recovery strategies. Thanks to a recent federal court decision, four luckier ones are finally getting overdue plans detailing steps needed to save and protect them, including identifying habitat they need to survive. But to make it happen, environmental groups […]
Farm salmon pose clear reproductive threat to wild gene pools, researchers say
While farmed salmon are genetically different to their wild counterparts, they are just as fertile. This is important information because millions of farmed salmon escape into the wild — posing threats to wild gene pools. The research team of a new study says farmed salmon should be sterilized to protect wild gene pools.
Salmon louse delay salmon returning to spawn
Outbreaks of salmon louse during smolt migration reduce the survival rate of the smolt and mean that salmon spend longer at sea before returning to spawn. The mortality rate among migrating smolt as a result of salmon louse corresponds to previous findings both abroad and in Norway, including over a longer time period in the […]
Tuscany’s ‘badlands’ acutely endangered
Vast fields of sunflowers, sprawling pine trees and slim cypresses, as well as vineyards as far as the eye can see — these are typical memories of Tuscany for all those who have been there. By contrast, a group of researchers is interested in the more barren aspects of the region in Central Italy: In […]
Second Annual Be Cruelty-Free Week Launches in 12 Countries
The global Be Cruelty-Free campaign to end animal testing for cosmetics launches its second annual Be Cruelty-Free Week with an infographic providing the tools to take action, the support of actress, dancer and former model Jenna Dewan Tatum, a video featuring cruelty-free beauty bloggers and a special promotion with Vegan Cuts.
Kentucky Becomes Eighth State to Ban Cruel Veal Crates
— In a move applauded by The HSUS, the Kentucky Livestock Care Standards Commission has issued rules that will prohibit the confinement of calves used for veal in crates so small, the animals are largely immobilized for their short lives.
Sterilise farmed salmon to save wild species, critics say
Farmed salmon escaping into rivers and the sea are posing such a threat to declining wild populations that sterilisation should be compulsory, researchers have concluded.
‘Tree of life’ distances are no shortcut to conservation
Some conservation strategies assume that the evolutionary distances between species on a phylogenetic ‘tree of life’ (a branching diagram of species popularized by Charles Darwin) can be used to predict how diverse their biological features will be. These distances are then used to select which species to conserve in order to maximize interesting biological features […]
