Fig. 5. A modified version of the scheme proposed by Carrington
(Carrington, 2002) to explain
the seasonal variation observed in tenacity, or attachment strength. While the
originally proposed energetic trade-off between gamete production and tenacity
is maintained, it is now proposed that an annual cycle of tenacity is due to
variation in thread quality, not quantity.
