BibTeX, biblatex and biber ⇒ References are not numbered

[ahmedlasheen]

Hello All
I am using plainnat bibliography style, one major problem problem is that the reference are not numbered, also in citation the hyper link is divided so there one box around author year and other box around author name, how can I make two boxed just a one box.
the following are mini example

Code: Select all

\documentclass[a4paper,preprint,review,12pt]{elsarticle}
\usepackage[T1]{fontenc}
\usepackage{mathptmx}
\usepackage{hyperref}
\biboptions{round,comma,authoryear}

\begin{document}
\section{Introduction}
first \citep{nicholson1996review}, second   \citep{saji1999dipole} 
\nocite{*}
\section*{Refernce}
\bibliography{africa}
\bibliographystyle{plainnat}
\end{document}

the bib file is

Code: Select all

I am using plainnat bibliography style, one major problem problem is that the reference are not numbered,

That's because you've set up author-year referencing:

Code: Select all

\biboptions{round,comma,authoryear}

If you remove authoryear you'll get numbers instead.

thanks for your answer
yes that's right when I remove the author year, the bibliography get numbers, but in citation I found that the author name and year disappeared, Actually in a lot of journal both citation are written with author name , year and also the bibliography has numbers so how can I have both things simultaneously.

thanks in advance
