Supplement 1. Richness response, ANPP, and climate data for all studies included in the meta-analysis.

File List encroach_div_data.txt (md5: f755284466bd9e2836b9171063d5b016) Description The encroach_div_data.txt file is a tab separate file. It contains the raw data used to calculate "community type" averages of richness response and ANPP. It also includes meta-data about each study included, such as the corresponding citations, study site location, study design, and yearly climate averages (precipitation and temperature). Column descriptions: 1. Community_Type = the name of the community type that the study was categorized as 2. Richness_Cit = the first author name and year for of each site richness data 3. ANPP_Cit = the first author name and year for of each site richness data 4. Location= the location where the study took place, usually a nearby city, wildlife refuge or research station 5. State/Province = U.S. state or Canadian province where the study took place 6. Encroaching_Species: species name of the predominate encroaching species in the study 7. Study_Design = the type of study design used to compare encroached and unencroaced richness ('WvG' denotes a binary comparison between encroached and unencroached treatments in the same year[s] with species richness expressed as the number of species per plot, 'Inven' denotes a binary comparison between encroached and unencroached treatments in the same year[s] with species richness expressed as the total number of species found in unencroached and encroached treatments, 'HC' denotes a binary comparison before and after encroachment occurred in the same plots with species richness expressed as the number of species per plot, 'REG' denotes a comparison of woody cover [%] to species richness in the same year[s] with species richness expressed as the number of species per plot) 8. Latitude = latitude of the study site (decimal degrees) 9. Longitude: longitude of the study site (decimal degrees) 10. MAP = mean annual precipitation at the study site (mm/yr)_ 11. MAT = mean annual temperature of the study site (°C) 12. Richness_Response: richness response (unitless) 13. ANPP_Unencroached = annual aboveground net primary productivity measured in unencroached plots (g/ 14. ANPP_Encroached = annual aboveground net primary productivity measured in encroached plots (g/m²) Missing values are represented as "---" Check-sum values are: Column 8 (Latitude): SUM = 1186.73; 0 values missing (rows with data: 30) Column 9 (Longitude): SUM = -31870.377; 0 values missing (rows with data: 30) Column 10 (MAP): SUM = 16652.360; 0 values missing (rows with data: 30) Column 11 (MAT): SUM = 324.211; 0 values missing (rows with data: 30) Column 12 (Richness_response): SUM = -19.494; 0 values missing (rows with data: 30) Column 13 (ANPP_Unencroaced): SUM = 4500.100; 13 values missing (rows with data: 17) Column 14 (ANPP_Encroached): SUM = 13248.200; 12 values missing (rows with data: 18)
