Also, ich mache das so:
In den Header:
Code:
\usepackage{natbib}
\bibpunct[]{(}{)}{,}{a}{}{,}
In den Body:
\begin{document}
\bibliographystyle{plainnat.bst}
% [...]
\paragraph{Imagine that $a$ and $f$ are linear functions of $z$, that is, $a(z)=\alpha z$ and $f(z)=\phi z$ where $\alpha$ and $\phi$ are constants, and from which follows $a(z) = \frac{\alpha}{\phi} f(z)$. This captures Trivers' and Willard's verbal model for why males are born in excess to female red deer in good nutritional condition \citep{triverswillard73}.}
% ...und noch ein Beispiel:
\paragraph{\citet{frankswingland88} showed that (using my notation throughout) when $f$, $a$ and $f/a$ are monotonically nondecreasing in $z$, and $f\not\equiv a$, sex ratios will be biased in favour of the sex produced in less favourable conditions. They applied an equilibrium criterion that allows solving for $z^*$ for specific probability distributions $P(z)$, shown below.}
