* Variables:
  * grid: grid cell at a resolution of 50 km * 50 km
  * Lat(°): the latitude of the corresponding grid
  * Lon(°): the longitude of the corresponding grid
  * PerInsect: The proportion of insect-pollinated species per grid level
  * MeanAge(Mya): the average mean age at grid level
  * MAT(°C): mean annual precipitation (MAT)
  * MAP(mm): mean annual precipitation (MAP) 
  * TSN: temperature seasonality (the mean value of temperature seasonality among all grid cells one species occurred)
  * PSN: precipitation seasonality (the mean value of precipitation seasonality among all grid cells one species occurred)
