There’s such beauty in variety – and the eggs laid by our terns show it too. In our newest paper we try to find patterns in this variety and test how female identity and age, as well as laying order, affect the colour, spottiness, shape, and size of eggs: doi.org/10.1002/ece3...

Why are alleles that increase disease susceptibility maintained in populations, when natural selection should eliminate them?

Which Kind of Science Reform
What hope is there for science reform, if we can't agree on what to reform? Right now, principles are more important than practices.
