Data on specialist and generalist herbivory, environmental variation, and phytochemical similarity from the Atlantic Rainforest of Brazil: 2013-2014

What: These are data on specialist and generalist herbivory from
naturally occurring Piper plants as well as
environmental data collected in 10 m diameter plots across sites in
the Atlantic Rainforest of Brazil. Data also include chemical
similarity calculated as the Morisita similarity index for species
in a given plot and chemical modules that demonstrate classes of
compounds that group together and influence herbivory. Why: Data were collected to understand factors that influence
herbivory and tropical forest richness with a particular focus on
secondary chemistry metabolomics. Where: Field sites include São Bento de Sapucaí (-22.8758,
-45.8581), Parque Nacional de Itatiaia (-22.3698, -44.6285), Parque
Estadual de Intervales (-24.3088, -48.2736), and Parque Estadual de
Serra do Mar - Núcleo Pincinguaba (-23.6200, -46.7222). When: Data were collected in the field from Dec 2013 – May 2014. How: Field data were collected in 10 m diameter plots centered on
randomly located Piper plants. Chemical data come from 1 H-NMR metabolomics.

数据概况：本数据集涵盖巴西大西洋雨林各采样点直径10米样地内自然生长的胡椒属（Piper）植物的专食性与广食性植食作用相关数据，以及同期采集的环境数据。数据集还包含以莫里西塔相似性指数（Morisita similarity index）计算得到的单样地内物种化学相似性，以及可体现化合物聚类类别并对植食作用产生影响的化学模块（chemical modules）。研究目的：本次数据采集旨在探究影响植食作用与热带森林物种丰富度的相关因素，重点聚焦次生化学代谢组学（secondary chemistry metabolomics）。研究区域：野外采样点包括圣本图-杜萨普卡伊（-22.8758, -45.8581）、伊塔蒂亚亚国家公园（-22.3698, -44.6285）、因塔尔韦斯州立公园（-24.3088, -48.2736）以及马尔山脉州立公园平钦瓜巴片区（-23.6200, -46.7222）。采集时间：野外数据采集于2013年12月至2014年5月期间开展。采集方法：野外数据以随机定位的胡椒属植物为中心，在直径10米的样地内完成采集；化学数据则通过氢核磁共振代谢组学（¹H-NMR metabolomics）方法获取。
