FIGURE 1 in A new species of lava lizard (Iguanidae: Tropidurinae: Microlophus) from the Galápagos
FIGURE 1. Phylogeny and haplotype networks of Galápagos lava lizards. Top: Phylogenetic tree (redrawn from Benavides et al. 2009) of species of Microlophus from the Galápagos and related continental species. Island of occurrence (islets excluded) is indicated in parentheses for Galápagos species; the western radiation is shown in red, and the new species described in this paper is in bold. The original tree was inferred through maximum-likelihood analyses of 56 terminals, including two from Floreana and one each from Gardner and Enderby islets, as well as 10 nuclear and four mitochondrial gene regions (Benavides et al. 2009). Bottom: Cytochrome b (Cytb) and NADH dehydrogenase subunit 2 (ND2) haplotype networks (redrawn from Benavides et al. 2009 and Torres-Carvajal et al. 2021, respectively) describing genealogical relationships among populations of lava lizards from Floreana and surrounding islets of Champion, Caldwell, Enderby, and Gardner. Black circles represent inferred haplotypes.

Deep-time reticulation and ancient mitochondrial genome capture during the radiation of Jamaican Anolis lizards (Squamata; Iguanidae)
<p>Gene flow and reticulation are increasingly recognized as important processes in the diversification of many taxonomic groups. With the increasing ease of collecting genomic data and the development of multispecies coalescent network approaches, such reticulations can be accounted for when inferring phylogeny and diversification. Caribbean <i>Anolis</i> lizards are a classic example of an adaptive radiation in which species have independently radiated on the islands of the Greater Antilles into the same ecomorph classes. Within the Jamaican radiation at least one species, <i>A. opalinus</i>, has been documented to be polyphyletic in its mitochondrial DNA, which could be the result of an ancient reticulation event or incomplete lineage sorting. Here we generate mtDNA and genotyping-by-sequencing (GBS) data and implement gene-tree, species-tree, and multispecies coalescent network methods to infer the diversification of this group. Our mtDNA gene-tree recovers the same relationships previously inferred for this group, which is strikingly different from the species-tree inferred from our GBS data. Posterior predictive simulations suggest that our genomic data violate commonly adopted assumptions of the multispecies coalescent model, so we use network approaches to infer phylogenetic relationships. The inferred network topology contains a reticulation event but does not explain the mtDNA polyphyly observed in this group, however coalescent simulations suggest that the observed mtDNA topology is likely the result of past introgression. How common a signature of gene flow and reticulation is across the radiation of <i>Anolis</i> is unknown; however, the reticulation events that we demonstrate here may have allowed for adaptive evolution, as has been suggested in other, more recent adaptive radiations.</p>
