Stick insects: Egg-laying techniques reveal new evolutionary map

Known for exceptional mimicry, stick insects have evolved a range of egg-laying techniques to maximize egg survival while maintaining their disguise -- including dropping eggs to the ground, skewering them on leaves, and even enlisting ants for egg dispersal. Scientists have now combined knowledge on these varied techniques with DNA analysis to create the best...

New insights on animal movement in fire-prone landscapes

A new Biological Reviews article considers how fire histories affect animals' movement and shape the distribution of species.

The review article also considers how novel threats of altered fire regimes, landscape fragmentation, and invasive species result in suboptimal movements that drive populations downwards. In addition, it raises key questions that, if addressed, will help clarify the...
