Dear Fellow Marmam Members,
I'd like to call your attention to a new paper entitled "Does diving
limit brain size in cetaceans?" by Marino et al. appearing in Marine
Mammal Science, 2006, 22(2), p. 413-425.
In this paper we address a longstanding hypothesis in the marine
mammal field about whether the oxygenation demands of diving have placed
a constraint on cetacean brain size. This notion - originally termed
the Dive Constraint Hypothesis and introduced by Robin (1973) - has
been addressed in various excellent papers through the years but a
question remained as to the status of the hypothesis up until now. In
our paper we apply a variety of statistical methods to a
phylogenetically-controlled sample of cetacean brain and body size data
to draw a final - and more definitive - conclusion about this
hypothesis that we discuss in the context of these previous findings.
Thanks for your time.
Regards,
Lori Marino
