During directional selection, advantageous trait values tend to become associated with earlier reproduction, accelerating the evolutionary response of the trait mean. This can lead to directional change even after selection has stopped:

Are Darwin's finches affected by climate change? Time-series analyses of beak and body traits, precipitation and temperature show finches are a resilient system, responding mainly to short-term weather variation rather than to long-term climate change:

Some Hawaiian cricket populations are losing the ability to sing. Males on Oahu invest more in sperm competition than males on Kauai by making more sperm and packing more proteins to increase sperm viability and slow female remating:

It’s time to publish responsibly! (And has been for a while, quite frankly...)

To help you do so, @nicolasgaltier.bsky.social and coauthors have put together a handy database of academia-friendly journals, DAFNEE. You can read about it in their article just out in @jevbio.bsky.social.
