Fig 1.
Boxes mounted upon poles to investigate marine nematode dispersal through air in the field.
Wooden boxes (H 25 x L 23 x W 23 cm) with shelter, containing 200 g defaunated algae, were placed on metal poles ca. 1.75 m above sediment level amidst salt marsh vegetation.

Different algal structures of Fucus vesiculosus: Receptacula, floating bladders and thalli.
Figure modified from Guden et al. [50].
Fig 3.
Average numbers of nematodes (mean ± SE) in the seawater (ca. 100 ml) in the open or gauzed (200 μm) boxes.
Letters indicate significant differences between treatments.
Fig 4.
Average numbers of nematodes (mean ± SE) in differently positioned boxes of the field experiment, which could be reached only through the air (‘air only’ boxes) or through the air and the water column (‘air + seawater’ boxes).
Letters indicate significant differences between treatments.
Fig 5.
Nematode abundance per cm2 (mean ± SE) on the inside and outside of the receptacula and floating bladders of Fucus vesiculosus.
Different letters above the bars indicate significantly different means.
