Contrasting relationships between pyloric caecum and gonad growth in the starfish Asterias rubens: Combined field and experimental approaches
The common starfish, Asterias rubens, occurs in fluctuating environments in the North Atlantic. To better understand energy allocation dynamics, we recorded gonad, body wall, and pyloric caeca (storage organ) indices between 2000 and 2004 from three different habitats. We applied a Fourier transform...
