Behavior and Its Neural Control in Gastropod Molluscs
In summary. negative geotaxis is favored by terrestrial gastropods that are about
to enter a protracted period of inactivity, since an elevated position will provide
protection against flooding. desiccation. and predation. When conditions change.
Ronald Chase Professor of Biology McGill University, 2002

Orientation and Communication in Arthropods
In both groups, geotaxis was positive on a dry substrate, but negative on a wet
one, as is the case on a natural beach. When a large black stripe occluding the
view of the horizon, thus simulating the dune crowned with its vegetation outline,
...
3.2 Geotaxis Figure 8.2 shows that Surirella gemma has a circadian rhythm in
geotaxis (Hopkins, 1966a). Negative geotaxis or upward movement before dawn
explains anticipation of dawn by river and pond silt populations (Round &
Happey, ...

Observations on the function and the structure of the ...
During positive geotaxis on a slope the anterior body side of the snail faces
downwards. It can be imagined that under these circumstances the statoliths
exert the greatest pressure upon the ventro-rostral part of the epithelium of the
statocyst.
Johannes Jacobus Geuze, 1968

minutes later five consecutive negative geotaxis tests were performed. If the
animal failed to turn around within 60 seconds a new trial was started and also ...

Comparative Psychology: A Handbook
(1995) reported that the High and Low geotaxis strains are fixed for alternate
alleles of alcohol dehydrogenase (Adh), amylase (Amy) and 6-
phosphogluconate dehydrogenase (Pgd). Thus, within each line genotypes for
these three allozymes ...

Oceanography and Marine Biology, An Annual Review
At these light levels, larvae have a natural tendency to ascend by means of a
negative geotaxis. Downward movement is initiated by exposure to light levels
that average about 0.23 log units above the photoresponse threshold. The rate of
...

Evolutionary Theory and Processes: Modern Perspectives: ...
With this in mind, we have also studied the effect of selection of D. melanogaster
for positive and negative geotaxis on recombination (Korol and Iliadi 1994).
Geotaxis is expressed as a preferential orientation of flies (up or down) with
respect ...

Evolution and the Genetics of Populations, Volume 3: ...
It appeared that the AR chromosome strongly favored negative geotaxis while AR
/CH was most favorable for positive geotaxis. Reverse selection for 7 generations
went far toward restoring neutral geotaxis and even relaxation carried the ...

For example, in probably the longest experimental evolution study on behavior in
a eukaryote (see also Travisano this volume), Drosophila were selected for over
five hundred generations for geotaxis, using a simple but ingenious setup that ...
