title: Data from: Parental frequencies and spatial configuration shape bumblebee behavior and floral isolation in hybridizing Rhinanthus

description: To shed light on the role played by pollinators in the diversification of
 angiosperms, focus is needed on how floral isolation varies locally in the
 early stages of plant divergence. The few studies performed so far have
 often used species pairs with distinct pollination syndromes and
 contrasting floral displays. Here, we focus on a hybridizing pair
 (Rhinanthus minor and R. angustifolius) with strong similarities in flower
 morphology and pollinators (bumblebees). We examined how ethological
 isolation changes locally in relation to relative Rhinanthus frequencies,
 spatial configurations, and pollinator assemblages. Interestingly, floral
 divergence based on adaptation to different pollinators is unlikely in
 Rhinanthus: no relationship was found between floral isolation and the
 local pollinator assemblage. In contrast, species frequency and spatial
 arrangement strongly influenced bumblebee behavior, ethological isolation,
 and thus potentially hybrid formation. When both Rhinanthus were present
 in equal proportions, bees generally preferred the more rewarding and
 conspicuous species. However, when the Rhinanthus frequencies were
 unbalanced, the more abundant species was preferred, although this was
 less pronounced when the less rewarding R. minor predominated. Ethological
 isolation is highly sensitive to site characteristics, and can be as high
 as in species with contrasting floral displays and pollinator suites, even
 though flowers are similar.
description: Complete dataset of
 bumblebee transitions in sympatric sites.This xlsb datasheet
 (created with Microsoft excel 2008 for Mac, version 12.3.2) contains the
 bumblebee behavior data collected in sympatric sites of Rhinanthus
 angustifolius and Rhinanthus minor (experimental populations, see in the
 publication). The file contains several sheets, the last sheet
 "Notes" describes each sheet separately. The sheet TD shows the
 transitions datas collected in the field, and the other TD... sheets are
 the transition data transformed in order to obtain a correct format for
 data analysis. The TDComptor sheet is a kind of resume that has been used
 for statistical analysis of the data using mainly JMP and R, and BI &
 ERI Analysor (B) contains all the information for the BI analysis. See
 further explanations in the publication and in the Note sheet. All the
 statistical analysis, graphs, data presented in the publication comes from
 this file and its monospecific equivalent (context). Note this file is
