Zebra mussels were transported
under all situations, but at very low numbers,
usually <0.5 mussel per duck per trip. The enhanced
zebra mussel densities, the extremely short distances
involved, and the fact that the ducks walked rather than
flew to the target pools suggest that these rates of transfer
overestimate the ability of waterfowl to transport zebra
mussels overland
So there goes the though that bird transferring zeb’s is undocumented. They only had a few ducks.
Just a few zebs and a couple hundred thousand duck/geese/loons/ect.
Great find!
True, but it also points out that their findings overestimate the ability for waterfowl to transport them in significant numbers. It would still be great to see a more extensive study than a short walk from one pool to another. I would think flight, and the water wicking ability their feathers have would show a significant decrease. I’ll keep digging…
There are multiple studies out there about veliger mortality, which are much easier to find than the waterfowl dynamic. Veligers are quite fragile, and temp swings, drying, turbulence, etc. experienced during a flight could potentially be enough to kill em. Just a thought.
