Yes, that is correct. Overall brood size did not differ, but the first clutch is larger in predation lines. That is perfectly in line with life history theory. That those offspring are also larger was surprising. Overall points towards 'all in early'

...thanks to postdoc Regina Vega Trejo and Hannah de Waele - this is her 'big' paper from her PhD. More on effects on cognition and social behaviour soon to come. How predation selects for swimming abilities in those selection lines came out yesterday: royalsocietypublishing.org/doi/10.1098/...
