Insects undergo complete metamorphosis, rebuilding their bodies, such as the transition from caterpillar to chrysalis to butterfly. The authors wondered why this extreme lifestyle might have evolved. Combining growth data and mathematical modelling, they found that insects grow much faster if they can grow and build the adult body in two separate stages, rather than doing both continuously. 

In this study, the use of open access satellite data for estimating Secchi disk depths in 3 lakes in Chile was investigated. In the oligotrophic Lake Panguipulli, no relationship was observed between estimated and measured Secchi disk depths. This highlight the need for methodological advances in the processing of satellite-derived water quality products,s, especially for very clear waters.

 The authors investigated the ecological effects of evolution of multiple zooplankton species of their community dynamics. The study highlights that species differ in their evolution-mediated ecological effects and showcases that using the evolutionary effects on ecology of single species to predict multiple species' effects may lead to unreliable predictions.
