"In our study, we find that urbanization speeds up tadpole development and increased behavioral plasticity. However, exposure to urban conditions also decreased tadpole size, which may cause adult frogs to become smaller and less attractive for mates" Read the full paper here: buff.ly/FxGf8KD

Awesome study, check it out!!

In some species, the function of the treehopper's pronotum (the body part that forms the crazy structures) is intuitive - for example, there are species that look like thorns, which presumably helps them hide from predators or injure attackers. But in many species, a function is not obvious...
