Science publishing works in mysterious ways

Why

• Is it (according to Web Of Knowledge, that is) "Environment and Development Economics" but "Environmental & Resource Economics"?
• Do publishers offer fancy templates for LateX files that violate their own journals' guidelines for authors?
• Does Web Of Knowledge abbreviate "Resource and Energy Economics" to "Resour Energy Econ", and "Energy Economics" to "Energ Econ"? (Note the savings in characters in the latter title: six characters! That'll save the rainforest.)

Indeed, why abbreviate journal titles at all?
