In contrast to classical breeding theory, our model suggests that multi-trait selection with gradual ...
Escape of pathogens is a particular concern since genetic change in (micro-)pathogens is usually much faster than the genetic change that artificial selection can create in animals, because of high mutation rates, shorter generation times, and much larger population sizes (e.g. [20]). As noted...

it is unknown whether non-human individuals can infer the potential consequences of others’ emotional expressions to make decisions in ecologically relevant contexts. That is, whether animals are capable of retrieving information from their memory about their experience with certain emotional displays, th...
