Biomineralization Using a Bioenergetic Approach." PLoS ONE 6(11): e27055.
    Otoliths are biocalcified bodies connected to the sensory system in the
inner ears of fish. Their layered, biorhythm-following formation provides
individual records of the age, the individual history and the natural
environment of extinct and living fish species. Such data are critical for
ecosystem and fisheries monitoring. They however often lack validation and
the poor understanding of biomineralization mechanisms has led to striking
examples of misinterpretations and subsequent erroneous conclusions in fish
ecology and fisheries management. Here we develop and validate a numerical
model of otolith biomineralization. Based on a general bioenergetic theory,
it disentangles the complex interplay between metabolic and temperature
effects on biomineralization. This model resolves controversial issues and
explains poorly understood observations of otolith formation. It represents
a unique simulation tool to improve otolith interpretation and
applications, and, beyond, to address the effects of both climate change
and ocean acidification on other biomineralizing organisms such as corals
and bivalves.

Is this how science illuminates "reality"? - "the meaning of an episode was
not inside like a kernel but outside, enveloping the talk which brought it
out only as a glow brings out a haze."
- narrator's comment about Marlow's tale-telling, in Heart of Darkness
