Species Interaction Dataset: Butterfly and Host Plant in Sierra Nevada (SE Spain)

Source: R/interaction.R
interaction.Rd

Data frame with co-occurrence records for the butterfly Agriades zullichi (butterfly) and its host plant Androsace vitaliana (host_plant) in the Sierra Nevada mountain range (SE Spain), combined with random background points. Contains 3 response variables (see interaction_responses) and 10 numeric environmental predictors at 100 m resolution (see interaction_predictors). The butterfly and host plant surveys were conducted independently by separate field teams; their presence records are spatially non-overlapping. Use interaction_extra() to download the associated environmental raster.

Format

A data frame with presence and background rows and 13 columns:

Response variables (3):

  • butterfly: Integer with three possible values: 1 (presence of Agriades zullichi), 0 (background), and NA (host plant observation site, where butterfly was not surveyed).

  • host_plant: Integer with three possible values: 1 (presence of Androsace vitaliana), 0 (background), and NA (butterfly observation site, where the plant was not surveyed).

  • class: Factor with three levels: "butterfly", "host_plant", and "background", indicating the observation type of each record.

Predictor variables - Remote sensing (3):

  • landsat_ndvi: Normalized Difference Vegetation Index derived from Landsat imagery.

  • landsat_pca_bands_123: First principal component of Landsat bands 1, 2, and 3 (visible).

  • landsat_pca_bands_457: First principal component of Landsat bands 4, 5, and 7 (infrared).

Predictor variables - Climate (5):

  • rainfall_annual: Mean annual rainfall (mm).

  • solar_radiation: Mean annual solar radiation (MJ m\(^{-2}\) day\(^{-1}\)).

  • temperature_annual_mean: Mean annual temperature (degrees C).

  • temperature_summer_max: Maximum summer temperature (degrees C).

  • temperature_winter_min: Minimum winter temperature (degrees C).

Predictor variables - Topography (2):

  • topographic_complexity: Index of terrain ruggedness and heterogeneity.

  • topographic_position: Relative elevation of a cell compared to its surroundings.
