Site : Site name X : X coordinate Y : Y coordinate Richness : Species richness taking into account individuals identified to the genus and species levels (based on data from the Vigie-Flore protocol for Flora (www.vigie-flore.fr), the STERF protocol for Rhopalocera (Manil and Henry, 2007) and the protocol of Lacoeuilhe et al. (2020) for Orthoptera) Richness2 : Species richness taking into account only the individuals identified to the species level Shannon_Diversity : Shannon index Abondance : For Flora, abundance is the total number of quadrats in which each species is present, and for Rhopalocera and Orthoptera, abundance is the total number of individuals CWM_dispersal : Community weighted mean (Garnier et al., 2004) for dispersal : For Flora, maximum seed-releasing height as a proxy for dispersal For Rhopalocera and Orthoptera, 3 classes of dispersal (1-Low dispersal, 2-Medium dispersal, 3-High dispersal) CWM_specialisation : Community weighted mean (Garnier et al., 2004) for specialisation : For Flora, Index θwb calculated using species co-occurrence data (Mobaied et al., 2015) For Rhopalocera, 4 classes of specialisation based on the optimal habitat of the caterpillar (1-Generalist species whose caterpillars grow in many types of habitat ; 2-Moderately generalist species whose caterpillars grow mainly in the associated habitat ; 3-Specialist species whose caterpillars grow mainly in the associated habitat ; 4-Specialist species with a very localised distribution) For Orthoptera, 2 classes of specialisation based on moisture preferences (0-Generalist species (mesophilic), 1-Specialist species (xerothermic and hygrophilic)) CWM_dep_pol : Percentage of times “insects” appears as a pollen vector for a given species across various databases (Martin, 2018) dPC_Flora_150m : Delta Probability of Connectivty (Saura & Pascual-Hortal, 2007) calculated for Flora with dispersal distances of 150m dPC_Flora_500m : Delta Probability of Connectivty (Saura & Pascual-Hortal, 2007) calculated for Flora with dispersal distances of 500m dPC_Rhopalocera_100m : Delta Probability of Connectivty (Saura & Pascual-Hortal, 2007) calculated for Rhopalocera with dispersal distances of 100m dPC_Rhopalocera_300m : Delta Probability of Connectivty (Saura & Pascual-Hortal, 2007) calculated for Rhopalocera with dispersal distances of 300m dPC_Orthoptera_100m : Delta Probability of Connectivty (Saura & Pascual-Hortal, 2007) calculated for Orthoptera with dispersal distances of 100m dPC_ Orthoptera _300m : Delta Probability of Connectivty (Saura & Pascual-Hortal, 2007) calculated for Orthoptera with dispersal distances of 300m IFT_Herbicides_100m : Average Treatment Frequency Indice for herbicides within a radius of 100m IFT_Herbicides_300m : Average Treatment Frequency Indice for herbicides within a radius of 300m Soil : Qualitative variable, divided into 2 categories: clay vs. sandy soil Humidity : Semi-quantitative variable based on site habitat vegetation, divided into 3 categories: 1 (xerophilous), 2 (mesoxerophilous), 3 (meso-hygrophylous) Floral_dispo : Average cover of flowering plants over the 4 visits on the site (%) Low_herbaceous_cover : Low herbaceous cover (<20 cm) on the site (%) Hight_herbaceous_cover : High herbaceous cover (>40 cm) on the site (%)
