Collembola
- Water and ion transport across the eversible vesicles in the collophore of the springtail Orchesella cincta
Summary: An inverse Ramsay assay and electrophysiology demonstrate that the eversible vesicles in the collophore of springtails absorb water and transport Na+, K+, Cl−, H+ and NH4+.
- How does the water springtail optically locate suitable habitats? Spectral sensitivity of phototaxis and polarotaxis in Podura aquatica
Summary: The hexapod Podura aquatica possesses at least two visual pigments and its polarization sensitivity functions in the shorter, blue spectral range following the tendency of polarotactic aquatic insects.
- Polarization sensitivity in Collembola: an experimental study of polarotaxis in the water-surface-inhabiting springtail Podura aquatica
Summary: In behavioural choice experiments, the water springtail Podura aquatica shows polarotaxis to horizontally polarized light as well as phototaxis.
