I'm more
interested in ecology, evolution,
social and systems, communication, etc., and less interested in
neuroscience, microbiology or anatomy...
(although I realize that one must still be versed in such areas). I'd
rather study the natural behavior of animals, in their natural
environment,
than create artificial lab experiments (mazes, etc.).

Can somebody help me in choosing the right program from the right
university?

Thanks

different "dialects", recruits of the one species were able to
correctly interpret the information relayed in the dances of foragers
of the other species, that use a different"dialect". My initial
intuitive response was a violent rejection!

Only later, upon a careful examination, did I realize that there was a
very good reason for my intuitive reaction:

Staunch "dance language" (DL) supporters are convinced that honeybee
dances, (that are not learned behavior), are "instinctive", (i.e.
genetically predetermined); that honeybees have a DL which utilizes
the spatial information contained in foragers'-dances; that different
species and strains of the genus Apis, use different "dialects' of
this DL; and that honeybees have an "instinctive" ability to correctly
interpret Dl information that is relayed in the "dialect" of their own
species. I accept none of this, but I will not explain why, because
this is not the point I wish to expose here.

The point I want to expose is this: Theoretically speaking, the
results obtained by Sue et al. could be due to recruits having somehow
acquired the ability to correctly interpret information relayed in a
different "dialect", or, (as DL opponents claim), recruits simply do
not use the information, so the "dialect" in which the information is
relayed, makes no difference.

To a DL opponent the second explanation is the only one acceptable. It
is also the more parsimonious of the two possible explanations. There
is, however, a far more basic reason to opt for the second
explanation. The reason is that the first explanation requires
honeybees to achieve the impossible! In order to correctly interpret
information relayed in a foreign "dialects", honeybees must know that
dialect. Assuming that they can "instinctively" know the "dialect" of
their own species, they still can, in no way, "instinctively" know a
foreign "dialect". The only way they can know this is by carrying out
the kind of scientific research that enabled Su et al. to learn that;
or else by reading the article that Sue et al. published about that
research. No one is prepared to even remotely consider the possibility
that honeybees can conduct scientific research, or learn by reading
the publication of other scientists. This leaves us with the only
possible solution, i.e. the conclusion that honeybees do not use any
DL information!

in the popular scientific news-media.

Every one knows of the "discovery" of the amazing honeybee "dance
language" (DL), which earned Karl von Frisch the Nobel Prize in 1973.
The existence of such a DL has never yet been experimentally
confirmed, in spite of an almost endless series of futile attempts, by
very many different scientist all over the world, during more than 60
years. Moreover, no one ever could experimentally confirm the
existence of such a DL, because v. Frisch's DL hypothesis was
stillborn, based on his own research, more than 20 years before its
inception. Staunch DL supporters, however, refuse to accept the demise
of their enchanting "dream", no matter what.

Sue et al. managed to establish, with considerable efforts, a viable
mixed honeybee colony, with workers of two different species, a strain
of the European Apis mellifera, and a strain of Apis cerana from the
Far-East, (as long as the queen was an A. cerana queen). Dance-
attendants presumably obtain and use direction-information from the
duration of the waggle-run of waggle-dances performed by their
foragers. The duration of waggle-runs in dances of one of the authors'
two species are, however, very different from the durations in the
dances of foragers from the other species. From the point of view of
staunch DL supporters like Sue et al. this means that the two species
each use a different "dialect". One would, therefore, expect that DL
information in the dances of foragers of the one species would
"mislead" dance-attendants of the other species.

Sue at al., however, found that dance-attendants were not "misled" by
dances of foragers from the other species than their own. The authors,
then, concluded that bees from each species somehow learned to
correctly interpret the distance-information provided by dancers from
the other species. Not surprisingly, the authors very seriously
believe they have made an incredibly amazing new discovery; even
though they cannot even begin to imagine how honeybees can accomplish
anything like that.

The answer is, of course, very simple, and very mundane. But trust
staunch DL supporters to completely miss it. Dance-attending recruits
were not misled by the "misleading" distance- information contained in
the dances of the foragers from the other species, not at all because
they learned to understand the other "dialect", but because they do
not use any DL information in the first place!

It is all utterly hilarious, and also very, very sad!
