Inbook citation not showing the section title

Question

reference for book section is not showing properly where the book section title is missing:

\documentclass[11pt,a4paper,twoside,openright,titlepage,fleqn,%
               headinclude,footinclude,BCOR5mm,%
               numbers=noenddot,cleardoublepage=empty,%
               captions=tableheading]{scrreprt}

\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage[style=nature, 
  citestyle=authoryear, 
  backend=biber, 
  natbib=true, 
  uniquename=false, 
  date=year,
  url=false,
  doi=false, 
  isbn=false,
  mincitenames=1]{biblatex}
\addbibresource{biblio.bib}

\begin{document}
this is not showing properly
\citep{CASESMITH2006}

\printbibliography
\end{document}

in biblio.bib:

@incollection{CASESMITH2006,
address = {Massachusetts},
author = {Case-Smith, Jane},
booktitle = {Hand Function in the Child},
chapter = {Hand Skill},
doi = {10.1016/B978-032303186-8.50010-1},
edition = {2},
editor = {{Henderson, Anne; Pehoski}, Charlene},
isbn = {9780323031868},
pages = {117--141},
publisher = {Elsevier},
title = {{Hand Skill Development in the Context of Infants' Play: Birth to 2 Years}},
url = {http://linkinghub.elsevier.com/retrieve/pii/B9780323031868500101},
year = {2006}
}

By default biblatex-nature suppresses titles of @inbook/@incollection entries. You can get the titles back with intitle=true for @inbook and @incollection.

Incidentally, there is a similar setting for titles of @article entries. articletitle=true is the default and displays article titles, but with articletitle=false you can suppress them.

See also the biblatex-nature documentation about articletitl and intitle.

Note that the name format of the editor field was incorrect (see How to properly write multiple authors in bibtex file?) and that normally the chapter field holds a numeric value (the chapter number) and not a (shortened) copy of the chapter title.

I would also like to mention that the combination of authoryear citation style and (numeric) nature bibliography style is not particularly fortunate. In a long bibliography with many entries it might be quite hard to find an entry from its author-year label since the year is located near the end, while the author name is at the front. The numbers in the bibliography also have no connection to anything else in the document and just add visual noise, in fact I believe they distract from the author name and make things harder to find.

\documentclass{article}

\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage[style=nature,

  mincitenames=1]{biblatex}

\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}

Note finally that you were using outdated and deprecated options to scrreprt, you should see warnings about that in the .log file.
