我正在使用Rmarkdown和RStudio和knitr写手稿。为了格式化参考文献，我使用了我从 https://www.zotero.org/styles 那里得到的《全球生态学与生物地理学》杂志的.csl文件。
我的问题是标题会自动转换为句子大小写。这对于小写的物种名称尤其成问题。
例如
Two types of morphophysiological dormancy in seeds of two genera (Osmorhiza and Erythronium) with an Arcto-Tertiary distribution pattern
成为
Two types of morphophysiological dormancy in seeds of two genera (osmorhiza and erythronium) with an arcto-tertiary distribution pattern
根据这个问题：如何设置对"句子大小写"的引用？，我应该从.csl文件中删除所有行，例如text-case=。问题是没有这样的台词，我的标题仍然被转换了。
作为奖励，我还想知道如何保持斜体的物种名称。

看起来knitr使用pandoc-citeproc进行引文呈现，并且您可以通过在标题周围使用另一组括号来保留大小写。请参阅 https://github.com/jgm/pandoc-citeproc/issues/269。
所以而不是
title = {Two types of morphophysiological dormancy in seeds of two genera (Osmorhiza and Erythronium) with an Arcto-Tertiary distribution pattern}
你会使用
title = {{Two types of morphophysiological dormancy in seeds of two genera (Osmorhiza and Erythronium) with an Arcto-Tertiary distribution pattern}}
另见 https://github.com/jgm/pandoc-citeproc/blob/master/man/pandoc-citeproc.1.md#titles-title-vs-sentence-case，
对于物种名称，请尝试textit{Osmorhiza}.(每 https://latex.org/forum/viewtopic.php?t=21255(
如果你想要大写和斜体的物种名称，另一种方法是将物种名称包装在标题的{emph{species name}}中。
例如：
@article{berra1973,
title = {A home range study of {emph{Galaxias bongbong}} in Australia}
}
@Rintze 在此示例中，需要使用双花括号的 Zelle 答案才能在"澳大利亚"中保留大写的"A"。
我使用 Zotero作为引文管理器和 RStudio 中的可视化编辑器来查找和填充 RMarkdown 文档的 .bib 文件，如果物种名称在 Zotero 的标题中用<i>species name</i>包装，RStudio 可视化编辑器会自动将<i>species name</i>替换为 .bib 文件中的{emph{species name}}。
