Figure 1.
Histogram of the Detectability of each pollinator modeled.
Despite some pollinator species show very high detectability, most show values below 10%.
Figure 2.
Frequency distribution of the number of models including five different potential co-variables of pollinator detectability (plus no covariate).
In grey the proportion of models retaining only one co-variable. Note that most models retained more than one co-variable (186 models; median of 2 variables retained; 30 models retained no co-variables).
Figure 3.
Observed and estimated visualization for one network (network MED2 in Bartomeus et al. 2008).
Pollinators (numbers) are represented in the upper level, and plants (letters) in the lower level. Box size is proportional to the total number of visits recorded, and the link size to the frequency of this particular link. A) Observed data. B) Links estimated with the hierarchical models, which incorporate pollinator detectabilities.
Figure 4.
Network parameters of the observed networks, and its paired estimated network.
Different colors are used for visualization purposes. A) Connectance, B) Linkage density, C) Nestedness, D) Robustness to pollinators extinction, E) Robustness to Plant extinctions and F) Specialization H2 index.
