Extended Data Fig. 1: Habitat use by IUCN red-list, endemic and range-restricted species across three land-cover types in Costa Rica.
From: Intensive farming drives long-term shifts in avian community composition
a, Forested habitats contained the greatest number of IUCN red-list, endemic and range-restricted species (LRT, P < 0.001; d.f. = 2, F = 4. 55.090). b, The number of endemic and range-restricted species was lowest in intensive agriculture and highest in forests, although diversified agriculture did not significantly differ from either group (LRT, P < 0.001; d.f. = 2, F = 4.709). c, The number of IUCN red-list species across all habitats. The greatest species richness is found in forest habitats (LRT, P < 0.001; d.f. = 2, F = 90.173). Diversified agricultural and intensive agricultural plots contained 59% and 39% of the endemic and IUCN red-list species found in forested habitats, respectively. Letters denote Tukey post hoc differences between groups in the number of species. Box plots show the median values and the first and third quartiles (25th and 75th percentiles), whiskers extend to 1.5× the interquartile range. Points represent transect-level values. a, nspp. = 62, ntransects = 44, nyears = 18. b, nspp. = 48, ntransects = 44, nyears = 18. c, nspp. = 12, ntransects = 44, nyears = 18. Summary statics for differences between groups in a–c are provided in Supplementary Tables 3–5.
