The bear captured both my immediate attention and subsequent thinking. (I had to look at the animal several times to determine that it was indeed a bear). Next, scanning around to make out the context of the bear, my eyes took in the hexagon around the animal: I concluded that the logo had to do with protection of the natural environment. Only after that did I "see" the words "Berlin University" and only in the last few seconds of diminishing attention did I finally decipher the small script beneath the text. So, to answer this query at long last, I would have responded "Other" to the question and referred to a "Natural Park" if one must specify what that "Other" association conjured in my mind.
I think it's a good start. Now it needs some more simplification. Too many details that fight for attention, rather than unify as a singular message. The academic tassel, for instance, does not read as such at first. The space the bear takes up in the hexagon is non-commital. It needs to be more dominant in relation to the space as a whole. I'm not sure what the significance or necessity of the hexagonal frame might be. Does the bear need to be complete? Could it just be its head? Could you then give it profile instead? Or at least 3/4? I think there is stronger iconography that associates with the Berlin reference that could be used to bolster the overall logo.
I'm not sure what David is referring to. But if you enlarged the bear to fill the space, even to break through the hexagon, break its plane, then you'd have something.
Thank you all for your invaluable feedback. The logo has completely changed. Much better that way, I think. Please see http://berlin-university.digital/de/
