A comparison of methods to assess selective disappearance and quantify ageing

Are current methods inaccurate in quantifying ageing & selective disappearance? We compare methods using simulations, analytical solutions, and empirical data, across life histories & methodologies (eg incomplete data). Surprising results & several recommendations. ecoevorxiv.org/repository/v...

Does early-life environment stress affect future reproductive investment? 🌊🐟
Our new paper found that when raised in fluctuating salinity, mosquitofish females produce eggs with lower protein, while older males had higher ejaculate glycogen content!

When feral cats are away, potoroos and bandicoots are more likely to play When feral cats are scarce, potoroos and bandicoots forage more freely, altering their behaviour and chances of survival.

How can we tell if potoroos & bandicoots are afraid of feral cats? With peanut butter balls, of course!
