Ontogeny of phototaxis
and metamorphic competence in larvae of the nudibranch Phestilla sibogae Bergh (Gastropoda: Opisthobranchia).
imbecillis that had completed their parasitic phase with chironomids (what I referred to as post-chironomid larvae) exhibited negative phototaxis
only in the presence of water that had been modified by U.
Spudich, "Two rhodopsins mediate phototaxis
to low- and high-intensity light in Chlamydomonas reinhardtii," Proceedings of the National Academy of Sciences of the United States of America, vol.
Males have obvious phototaxis
. The second generation of eggs begins to hatch in the middle of July, with pupation beginning in mid to late August and adult emergence in early September.
Lids sidewalls where covered with black tape to avoid phototaxis
. Seven minutes after the introduction of the larvae, the number of individuals within a 30 mm radius from each filter disc and the larvae that remained between both 30 mm radius were counted.
Agents were evolved for goal seeking (phototaxis
) task and their performance were tested in the presence of sensorimotor and structural perturbations and for different levels of neural noise during agent lifetime.
However, a common misunderstanding is that this attraction represents a positive phototaxis
. Contrary to this belief, Thompson (1917), Verheijen (1958), Mazokhin-Porshnyakov (1969), Janzen (1983), and more recently Nowinszky (2003) observed that insect attraction to lights is the result of navigational confusion.
as a behavioral component of diel vertical migration in a pelagic Daphnia.
These orchids had adapted by pointing upward to seek sunlight (positive phototaxis
) and opposing gravity.
Escape behavior mediated by negative phototaxis
in the scorpion Paruroctonus utahensis (Scorpiones, Vaejovidae).
Beetles were observed to have a positive phototaxis
whether flying or running.
Both species use a statocyst to detect changes in gravity (geotaxis) and a photoreceptor to detect changes in light (phototaxis
