Preise
ISZS - Student Integrative Science Prize 2009. Dieser Preis wurde erstmalig von der DZG vergeben. Er
ist mit 100 € dotiert und wurde von der ISZS gestiftet. Ausgezeichnet wird eine Arbeit, die einen integrativen
Ansatz erkennen lässt.
Urkundentext: “The International Society of Zoological Sciences has announced an award for students to be
delivered during major meetings of national zoological societies around the world. The Student Integrative Science Prize
rewards research conducted at a post-graduate level as part of a Doctor of Philosophy or Masters qualification that utilizes
more than one field of zoology or attempts to integrate zoology with other sciences or non-sciences. The selection
panel for this Award was chaired by Professor Jurgen Heinze, a member of the ISZS Executive Committee. The ISZS is
proud to present the very first of these awards at the 102nd Meeting of the German Zoological Society.”
Gewinner sind Lisa Rath, Missanga van de Sand, David
Gustav und C. Giovanni Galizia, Neurobiologie, Universität
Konstanz.

Generalization and discrimination of stimuli determine the
perceptual space of both animals and humans and are
needed to effectively distinguish and integrate environmental
signals. However, it remains unclear whether discrimination
and generalization boundaries are genetically

encoded or experience dependent. Honeybees and humans
show remarkable similarities in the architecture of
their olfactory system, we therefore analyzed the impact of
learning and perceptual history on generalization in both
species. Bees as well as humans were trained on two odours
which occurred at three different frequency ratios in
12 trials. We conditioned the bees in an appetitive Pavlovian
paradigm differentially (CS+/CS-) and recorded their
proboscis extension reflex. In humans, we presented the
two odours as “odour 1” and “odour 2” to the participants
prior to the experiment. During training and test, participants
had to rate the stimuli in a forced choice as either
odour 1 or odour 2. We measured the degree of generalization
by recording the responses to a novel odour after
the training. Our findings show an impact of the frequency
ratio an odour occurred during training on the degree of
generalization after learning. In both species, the novel
odour was more frequently generalized toward the odour
that had occurred less often during the training trials. Possibly,
a higher incidence of training trials leads to a more
distinct neural template for the odour, moving the novel
odour away from it.
Die Gewinner der drei Geldpreise wurden auch 2009 von den Tagungsteilnehmern
ausgewählt. Zusätzlich prämiert wurden wieder die besten Poster jeder der acht
Fachgruppen, die jeweilige Jury wurde von den Fachgruppen bestimmt. Die besten
Poster wurden nach dem Abendvortrag am letzten Tag vorgestellt und die
Gewinner der Fachgruppenwettbewerbe erhielten dort Urkunden aus der Hand des
Präsidenten Prof. Dr. Wolf-Michael Weber. Wobei hier erwähnt werden sollte, dass
die Fachgruppe Morphologie ihr bestes Poster zusätzlich mit 50 € aus den eigenen
Reihen auszeichnete. Die von der DZG gestifteten Geldpreise wurden samt
Urkunden zu Beginn des Gesellschaftsabends im "Leeren Beutel" verliehen.
