Code and example data to calibrate the niche model of food webs based on allometric relationships
收藏资源简介:
#### READ ME ################################### The code has the following structure # 1. Loading of an artificial dataset of i) predator-prey interactions, ii) body size distribution, iii) hypothetical species presence/absence lists # 2. Definition of functions run for the analysis # 3. Calculation of the observed parameters for the niche model # 4. Inferrence of the parameters for all species in the metaweb ## Name of the parameters of the niche model # n: niche position along the niche axis # c: centroid of the niche # r: range of the niche
#### 自述文档 ################################### 本代码的组织结构如下: 1. 加载三类人工数据集:① 捕食者-猎物互作数据、② 体型大小分布数据、③ 假想物种的存在/缺失列表 2. 定义本次分析所需的各类函数 3. 计算生态位模型(niche model)的观测参数 4. 推断元食物网(metaweb)中所有物种的模型参数 ## 生态位模型的参数名称 n:沿生态位轴的生态位位置 c:生态位的质心 r:生态位的幅度范围
