For example, the geotactic plus recipient population received geotactically
negative flies from the geotactically positively selected population. The numbers
given are the scores in the mazes. High numbers mean a high frequency of
positive ...

The Physiology of Insecta
Ammophila larvae (Baerends, 1941) and caterpillars of Platysamia (van der Kloot
and Williams, 1953a) direct their position within cocoons according to gravity;
and even crawling caterpillars frequently react negatively geotactically (Lammert,
...

Pacific Salmon Life Histories
Bams (1969) found that pink and sockeye salmon alevins develop both
geotactically-directed emergence behaviour and positive rheotactic behaviour
near the end of the intragravel period. Development of intragravel behavior in
pink salmon, ...
Cornelis Groot, L. Margolis, 1991
Pyle (1976) found females from geotactically divergent maze-selected strains of
Drosophila melanogaster to differ in their utilization of oviposition sites given a “
choice” between a lower and an upper (inverted) egg-laying surface. Murphey

The social biology of ants
Ants only orient themselves exclusively geotactically, or phototactically in the
rarest cases in the natural environment ; they generally orient themselves by a
combination of the two, and combinations of both or one method with chemical ...

Marine ecology: a comprehensive, integrated treatise on life ...
Occasionally, however, Gamble and Keeble (1903) found individuals which
lacked the statocyst ; these individuals did not respond geotactically. The
holothurian Synapta digitata normally burrows vertically, head first; it has 5
statocysts close ...
Under experimental conditions, if the sun is mirrored into the hive from below, a
dancing bee may alternatively orient herself geotactically and phototactically.
External temperature seems to have little influence on dance frequency. A
dancing ...

108) ; that is, certain animals showed a very marked positive geotaxis ; others, an
equally decided negative tendency ; and a few, perhaps one animal out of 12 or
15 where 10 or more tests were made, were apparently geotactically indifferent.

Physiological Plant Anatomy
Possibly the terminal vacuoles, containing minute crystals, which occur in
geotactically sensitive Desmids [Closterium, etc.,], likewise represent sensory
organs. If plants of Caulerpa prolifera are darkened for some time, their " leaves."

Gottlieb Haberlandt, 1965
Several weeks before normal emergence, alevins develop the potential for
geotactically directed emergence behaviour, which enables them to reach the
open water of the creek with the least effort and along the shortest route. This
behaviour ...
