Scientists train endangered carnivores to avoid poisonous toads

Stack of books Buy propecia c.o.d., Invasive cane toads in Australia have been killing off endangered marsupials called northern quolls, who can’t seem to help snacking on this toxic species.

Fisheries take heavy toll on marine turtles

Computer system tracks penguins by their chest markings

African penguins at Robben Island Order diazepam, A new computer system could help scientists monitor the status of threatened penguins by automatically identifying patterns on the birds’ chests, according to a study in Endangered Species Research.

In the past, scientists have tracked penguins by outfitting the birds with metal flipper bands. Cheap diazepam overnight delivery, But these bands can affect the penguins’ swimming and foraging, and birds are sometimes harmed when the bands start to open.

Because the patterns don’t change over time, Acheter en ligne diazepam, Ordering diazepam no prescription, a computer program can use them as “fingerprints” to identify individual animals in an image.

The researchers tested the system by setting up a camera along two “penguin highways” on Robben Island, South Africa, Kjøp Discount diazepam, Minnesota MN Minn. , where African penguins frequently travel.
