BibTeX, biblatex and biber ⇒ Italics in book titles

[Loupiote3]

Dear all,

Please excuse me for asking this question as there is probably an easy fix but haven't been able to find it online and have been out of using Latex for a couple of months so I am a bit rusty…

I have a number of book titles with species names in them. BibTex is automatically putting my book titles in italics, which is fine. But seeing that species names are normally italicised, when they are in a title which is already in italics one is supposed to de-italicise the species name (if that makes sense). And I have no idea how to do this!

For instance, I have:

Cranial shape variation in \textit{Homo erectus}
or
Cranial shape variation in Homo erectus

which compiles as:

Cranial shape variation in Homo erectus

But I want:

Cranial shape variation in Homo erectus

Does anyone know what to do to rectify this?

Many thanks!

Use emph instead of textit.

Back on my computer I thought i would provide a more robust solution.

Naturally, defining a new semantic command comes to mind for this kind of stuff. So i looked up the original definition for \emph and modified it to create a new command \species.
