Palm-Pitviper (Bothriechis) Phylogeny, mtDNA, and Consilience

Abstract

The phylogeny of the neotropical palm-pitviper genuswith Ophryachus as the sister lineage. Crother et al. Bothriechis has been previously inferred from morphol-(1992) inferred the phylogeny of Bothriechis with alloogy and allozymes. These nuclear-based data sets were zymes and morphology and found the two data sets found to be congruent and also consilient with the geoto be congruent (Fig. 2). They (Crother et al., 1992) also logic history of the region. We present mtDNA sequence detailed the historical biogeography of Bothriechis and data as an additional data set in the inference of the models of the vicariant history of Middle America Bothriechis phylogeny and analyze it separately and comand determined these to be entirely consilient with bined with previous data. The mtDNA phylogeny is their phylogenetic hypotheses of Bothriechis relationincongruent with the nuclear data sets. Based on a numships.

AFLPs RESOLVE PHYLOGENY AND REVEAL MITOCHONDRIAL INTROGRESSION WITHIN A SPECIES FLOCK OF AFRICAN ELECTRIC FISH (MORMYROIDEA: TELEOSTEI)

“…Instead, the AFLP data generally support the phylogenetic integrity of the phenotypically defined groups and indicates their independent dispersal to multiple localities. These conclusions are similar to those reached in a number of other recent phylogenetic studies in which morphologically inferred relationships among closely related organisms were found to conflict with mitochondrial geneaology, but were supported by nuclear sequence data (Sota andVogler 2001, 2003;Taggart et al 2001;Shaw 2002;Sota 2002;Rognon and Guyomard 2003) or AFLPs (Albertson et al 1999;Parsons and Shaw 2001).…”

A relict lineage and new species of green palm-pitviper (Squamata, Viperidae, Bothriechis) from the Chortís Highlands of Mesoamerica

“…Castoe et al (2009) and Daza et al (2010) provided the most recent phylogenetic estimates for nine species of Bothriechis , as part of a comparative phylogeographic study of three co-distributed, predominantly Mesoamerican genera of pitvipers. Their phylogenetic hypotheses supported the contention of Castoe and Parkinson (2006) that Bothriechis lateralis is the sister group to the Nuclear Central American highland species of the genus ( Bothriechis aurifer , Bothriechis bicolor , Bothriechis marchi , Bothriechis rowleyi , and Bothriechis thalassinus ) and rejected the Crother et al (1992) and Taggart et al (2001) estimates that Bothriechis lateralis is the sister clade to Bothriechis bicolor . Our phylogenetic hypothesis also supports a Nuclear Central American clade, with Bothriechis marchi and Bothriechis thalassinus in the Chortís Highlands comprising a group that is sister to Bothriechis aurifer , Bothriechis bicolor , and Bothriechis rowleyi from the Nuclear Central American highlands to the west.…”

“…Available molecular data for these two taxa are limited to a single sample assigned to each nominal form, which indicate the two are sister species nested within a Nuclear Central American clade (also including Bothriechis aurifer , Bothriechis bicolor ,and Bothriechis rowleyi ) that is, in turn, sister to the highland Bothriechis (i.e. Bothriechis lateralis and Bothriechis nigroviridis ) found in lower Central America (Taggart et al 2001, Castoe and Parkinson 2006, Castoe et al 2009). …”

Reticulate evolution in nuclear Middle America causes discordance in the phylogeny of palm‐pitvipers (Viperidae: Bothriechis)

“…(b) Phylogeny of Taggart et al. () based on 12S sequences with a monophyletic northern Middle American clade suggesting a northward invasion. (c) Phylogeny of Doan et al.…”

“…The earliest phylogeny of Bothriechis was based on morphology and allozyme data (Crother, Campbell, & Hillis, ) and suggested a complex biogeographic history based on a recovered clade containing both nuclear Middle American and southern Middle American taxa (Figure a). Later, the incorporation of mitochondrial data resulted in the recovery of an incongruent topology (Taggart, Crother, & White, ), with a monophyletic nuclear Middle American clade (Figure b). Subsequent phylogenies supported this, but were similarly driven by mitochondrial sequence data.…”
