How to define in LaTeX a new counter that includes the chapter number too?

Question

Given I have defined a new environment for which a counter is maintained:

\\newcounter{bioclipse}
\\newenvironment{bioclipse}[2][]{
   \\begin{shaded}\\refst         


        

Answer 1

Insert:

\def\thebioclipse{\thechapter-\arabic{bioclipse}}

and get

\newcounter{bioclipse}
\def\thebioclipse{\thechapter-\arabic{bioclipse}}
\newenvironment{bioclipse}[2][]{
   \begin{shaded}\refstepcounter{bioclipse}\par\medskip\noindent%
   \textbf{Bioclipse Excursion~\thebioclipse #1: #2
   \vspace{0.1cm} \hrule \vspace{0.1cm}}
   \rmfamily}{\medskip \end{shaded}
}
