Description
The program_agro.txt
file is program file for Turbo Pascal v. 5 for a randomization model used
to compare species composition (i.e., proportion of species in nests) in natural
and artificial nests. The readme.txt
file contains variable and subroutine descriptions. The HIT.dat
is a sample data file with three columns as follows:

1 = species list

2 = number of artificial nests per species

3 = number of natural nests per species

数据集说明
program_agro.txt 为适配Turbo Pascal 5.0版本的程序文件，其所实现的随机化模型可用于对比自然巢穴与人工巢穴中的物种组成（即巢穴内物种占比）。readme.txt 文件包含本数据集的变量与子程序说明。HIT.dat 为示例数据文件，共包含三列，具体如下：

1. 物种列表
2. 各物种对应的人工巢穴数量
3. 各物种对应的自然巢穴数量
