First thing to do is to add a field for the journal abbreviation to the article entrytype, journalabbr in the MWE. Therefore you need to declare a datamodel (an extra file; in the MWE I've used filecontents to simulate that) and you have to tell biblatex/biber to use it in the package options.
Then you have to modify the cite command, so it fits your needs. \citep from the authoryear-style (your citestyle) uses the \cite command. There you just have to add a switch, which checks if the field journalabbr is empty or not, and prints it out or not.
Last but not least you have to add the abbreviation fields to the entries.

\printbibliography

Copy
humannat.bstashumannat-mod.bstin the same directory as your main TeX file.Open it with any text editor and change the two occurrences of
into
Then change
\bibliographystyle{humannat}into\bibliographystyle{humannat-mod}, rerun LaTeX and BibTeX, then LaTeX again.To get parentheses around the year, go to line 155 in
humannat-mod.bstto findExchange the position of the
%, to getYou'll get
Changing the period to a colon would require major surgery. Better going with
biblatexif you need to customize reference lists.
