The widespread species of Meenoplidae (ME), Delphacidae (DE), Tropiduchidae (TR) and Flatidae (FL) (Figure 5A) are exotic species (Figure 5B). Likewise, the indigenous species of Cixiidae (CI) are closely associated with indigenous non-endemic or endemic plants (Figure 5C). At the sub-classes plant level no particular pattern appears (Figure 5D). Notes: see Figure 2.

Figure 4. MCA with endemic insects on dicotyledons. The planthopper families (Figure 4A) with endemic species (Figure 4B) are distributed essentially on endemic or indigenous nonendemic plants (Figure 4C) except for Issidae (IS) which is associated with indigenous plants but also for some species (Borbonissus spp.) with numerous exotic plants (PEX). At the subclasses plant level no particular pattern appears (Figure 4D). Notes: see Figure 2.

FIGURE 3 in Interrelationships and history of the slit-eared skinks (Gongylomorphus, Scincidae) of the Mascarene islands, based on mitochondrial DNA and nuclear gene sequences
FIGURE 3. Phylogeography of Gongylomorphus skinks in Mauritius based on 1102bp of combined mtDNA sequence data. Lower-case letters refer to collection localities in Fig. 1 and Table 1. Haplotype networks are drawn with the areas of circles proportional to number of individuals observed; dots represent unobserved haplotypes, and lines between them each represent a single nucleotide substitution. Filled circles represent samples collected from extant populations, and open circles samples from extinct ones.

FIGURE 2. Bayesian maximum likelihood tree for extinct and extant Gongylomorphus skinks and a range of outgroup taxa, based on 1473 bp of combined mitochondrial (12S rRNA, cytochrome b) and nuclear (c-mos) DNA sequence. Numbers adjacent to nodes indicate: Bayesian posterior probability/MP bootstrap support values for analyses conducted using all samples (top line, if present), and only a subset of samples with full-length sequence for all three genes (bottom or only line). Letters a-s indicate the sampling locality in Mauritius for each specimen (Fig. 1, Table 1). Letters in bold are specimens which were sequenced for all three genes. Letters suffixed by an * are specimens that represent extinct populations.
