Implication

Randomized survey examines bird species richness affected by landscape structure in rice agroecosystems, suggesting eco-friendly practices.

Key Points

  • This research aims to understand how field- and landscape-scale features influence bird species richness in rice fields in Guinea-Bissau.
  • Bird surveys were conducted along nine transects during two rice-growing cycles (2021-2022).
  • Both field variables and landscape metrics were derived from satellite imagery.
  • Species richness was estimated using Bayesian models, and relationships with environmental predictors were assessed with linear mixed models.
  • Identified a total of 150 bird species with an average species richness of 18.2 per transect survey.
  • Field tree cover increased invertivore and frugivore richness by 17.0% and 16.4% of the standard deviation, respectively.
  • Bird richness was more significantly influenced by landscape structure than by field features, especially for frugivores and invertivores at broader scales.
