Herpetological Highlights

Bradykinin is a hormone that is released naturally in response to tissue damage, so if you hurt yourself, it makes it hurt. Quite a few animals from wildly different evolutionary histories have defensive toxins which are fake copies of this hormone. We discover which animals have them, when these defences evolved, and ultimately, how they are used for defence. For our Species of the Bi-Week there have been multiple new rock monitors discovered - slender predators of Australia's rocky outcroppings.

Invasive species are well known to damage ecosystems by directly eating other animals and disrupting the food chain. But their impacts can go much deeper, as a new study about seed dispersal by pythons and tegus in the Everglades has shown - they may be contributing to the destruction of rare and unusual habitats.

Mimic poison frogs are utterly amazing, famous for mimicking multiple different frog species, and like other dart frogs they demonstrate bi-parental care where both male and female frogs team up to look after the young. What we didn't know was how flexible these parental roles are - can females step in to move tadpoles when males start slacking, and what triggers them to do so? It turns out they can, but they don't always.

Common knowledge suggests that albino animals are rare in the wild because they stick out like a sore thumb and get eaten by predators, but studies supporting this are relatively scarce. Now, researchers from Australia have discovered that the drawbacks of albinism are not limited to their obvious appearance. Even better, they used our old friends cane toads to prove it.
