=============================================================================DESCRIPTION=============================================================================This dataset contains the data used in the analyses of the manuscript "Specialisation matters: Landscape structure shapes the distribution of Plutella xylostella and its parasitoids", accepted for publication in the Journal of Applied Entomology. =============================================================================DATA DESCRIPTION=============================================================================The data include: 1. Host abundance: - Inmaduros: total immatures (larvae + pupae) of Plutella xylostella 2. Parasitism counts: - Diadegma: number of Diadegma leontiniae emerged - Siphona: number of Siphona sp. emerged 3. Landscape metrics (calculated for brassica host patches): - CA_Host: total area of brassica patches - AREA_MN_Host: mean patch area (MAREA) - PROX_MN_Host: mean proximity index (MPROX) - AREA_MN_No_Hosp_Grande: mean area of non-host patches (MNHAREA) 4. Temporal variables: - Fecha: sampling date - Año: sampling year (2021, 2022, 2023) =============================================================================METHODS=============================================================================- Data were collected during spring-summer seasons (September to December) of 2021, 2022, and 2023.- Landscape metrics were calculated using FRAGSTATS v4.2.- Variables were scaled (mean = 0, sd = 1) prior to analyses.- The effect of year (Año) was included as a fixed factor.- Date (Fecha) was included as a random intercept. =============================================================================FILE DESCRIPTION=============================================================================File name: Plutella Argentina.xlsxSheet name: Todo_BFormat: Excel (.xlsx) Column headers:- Fecha : Sampling date (dd/mm/yyyy)- Año : Year (2021, 2022, 2023)- Inmaduros : Total immatures of P. xylostella- Diadegma : Diadegma leontiniae emerged- Siphona : Siphona sp. emerged- CA_Host : Total area of brassica patches (hectares)- AREA_MN_Host: Mean area of brassica patches (hectares)- PROX_MN_Host: Mean proximity index- AREA_MN_No_Hosp_Grande: Mean area of non-host patches (hectares) =============================================================================REPRODUCIBILITY=============================================================================This dataset contains all variables used in the statistical models reported in the manuscript. The complete results (coefficients, confidence intervals, and model-averaged estimates) are reported in the paper.
