资源简介:
These data are species lists for each study setting (i.e. MI blueberry, MI Cherry, Oregon, blueberry, and California watermelon). The data present two main pieces of information: (1) species occurrence and abundance & (2) species functional traits.<br><br><br>The occurrence of each species is denoted by a '1' for each site type ('EE" = enhanced edge, 'CE' = control edge, 'EC' = enhanced crop, 'CC' = control crop). The column 'Abund' gives to total nujmber of specimens collected across these site types for both years (2015 & 2016).<br>The functional traits are lecty, sociality, nest location and intertegular distance (ITD, a body size metric). The first 3 traits are categorical, their categories are:<br><b>Lecty</b> - polylectic ('pol') or oligolectic ('oli')<b>Sociality</b> - solitary ('sol'), social ('soc'), or faculatively social ('fac')<b>Nest location</b> - soil, stem, cavity, wood<b><br></b><b>ITD</b> is given in mm.<br>The categorization of these traits follows other published resources (see Methods and Appendices in Nicholson et al 2019 <i>Ecology Letters</i>). For some species traits have not been published and these are given a 'NA' value.<br>
本数据集为各研究样地的物种名录,涉及的研究样地包括密歇根州蓝莓(MI blueberry)、密歇根州樱桃(MI Cherry)、俄勒冈州(Oregon)样地、蓝莓样地以及加利福尼亚州西瓜(California watermelon)样地。本数据集包含两类核心信息:(1) 物种出现情况与种群丰度;(2) 物种功能性状。
各物种在对应样地类型中的出现情况以数值"1"标注,其中样地类型定义如下:"EE"为增强边缘样地(enhanced edge)、"CE"为对照边缘样地(control edge)、"EC"为增强种植样地(enhanced crop)、"CC"为对照种植样地(control crop)。列名为"Abund"的字段代表2015年与2016年两年间,在上述所有样地类型中采集到的标本总数量。
功能性状包括采食专性(lecty)、社会行为(sociality)、筑巢位置(nest location)以及翅基间距(intertegular distance, ITD,一种体型大小度量指标)。前三项性状均为分类变量,其分类标准如下:
**采食专性(lecty)**:分为泛食性('pol',polylectic)与寡食性('oli',oligolectic)两类;
**社会行为(sociality)**:分为独居性('sol',solitary)、社会性('soc',social)以及兼性社会性('fac',facultatively social)三类;
**筑巢位置(nest location)**:分为土壤、茎秆、孔洞以及木材四类;
**翅基间距(ITD)**的单位为毫米(mm)。
上述性状的分类标准参考已发表的相关研究(详见Nicholson等人2019年发表于《Ecology Letters》的研究方法与附录部分)。若部分物种的相关性状尚未见公开报道,则以"NA"标注其缺失值。
