Note: Cañas in 2012 and Mateo in 2017, were desiccated by management of invasive species (mainly American crab) and by use of water for irrigation, respectively. Laxe in 2000 was naturally desiccated (evaporation), and Louro (retro dune lagoon) in 2010 suffered a brackish water event.

Table 3. Distribution of individuals in eight ranges of HI/HET resulting from Introgressed. North-central Spain included 68 samples (33I. elegans -like and 35 I. graellsii -like) and north-west included 40 samples (21 I. elegans -like and 19 I. graellsii -like. All hybrids (F₁ and F₂) were a priori, morphologically identified as I. graellsii,which is consistent with the morphology of the F₁ and F₂ hybrids from the laboratory (Monetti et al., 2002; R. A. Sánchez-Guillén et al., 2005) which usually resemble I. graellsii individuals.
