Biome occupancy data used in "The effect of single biome occupancy on the estimation of biome shifts and the detection of biome conservatism"

Data files for running BioGeoBEARS analysis on biomes occupied by New Zealand Chionochloa, Coprosma, Melicytus, Myrsine, Pseudopanax, Poa X, Rytidopserma A, Rytidosperma B, and Veronica. Each clade has a geog file for a multiple biomes per species approach (_geog_file_multi.txt), and a single biome per species approach (_geog_file_single.txt) so analyses can be run both ways. Time stratification to control biome availability uses the areas_allowed.txt and time_periods.txt files, which make Forest always available, Open available from 4 Ma, and Alpine from 1.9 Ma.

本数据集提供了用于针对新西兰雪穗茅属（Chionochloa）、柱果木属（Coprosma）、蜜球木属（Melicytus）、杜茎山属（Myrsine）、假楤木属（Pseudopanax）、早熟禾属X（Poa X）、糙芒草属A（Rytidopserma A）、糙芒草属B（Rytidosperma B）及婆婆纳属（Veronica）所占据的生物群系运行BioGeoBEARS分析的数据文件。每个演化支均配有两类地理文件：分别适配"单物种多生物群系"分析方案的_geog_file_multi.txt，以及适配"单物种单生物群系"分析方案的_geog_file_single.txt，可支持两种分析模式的开展。用于管控生物群系可获得性的时间分层校准流程，将借助areas_allowed.txt与time_periods.txt两个文件实现：其中森林生境始终可用，开阔生境自4百万年（Ma）起可用，高山生境自1.9百万年（Ma）起可用。
