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). </p> <p>Column descriptions:</p> <p>1. Community_Type = the name of the community type that the study was categorized as</p> <p>2. Richness_Cit = the first author name and year for of each site richness data</p> <p>3. ANPP_Cit = the first author name and year for of each site richness data</p> <p>4. Location= the location where the study took place, usually a nearby city, wildlife refuge or research station</p> <p>5. State/Province = U.S. state or Canadian province where the study took place</p> <p>6. Encroaching_Species: species name of the predominate encroaching species in the study</p> <p>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)</p> <p>8. Latitude = latitude of the study site (decimal degrees)</p> <p>9. Longitude: longitude of the study site (decimal degrees)</p> <p>10. MAP = mean annual precipitation at the study site (mm/yr)_</p> <p>11. MAT = mean annual temperature of the study site (°C)</p> <p>12. Richness_Response: richness response (unitless)</p> <p>13.
