Figure 1 in Range extension to Santo Domingo de los Tsáchilas province and revised distribution of Platyrrhinus chocoensis (Phyllostomidae: Chiroptera) in western Ecuador
Figure 1. Frontal (A) and lateral (B) views of a live specimen of Platyrrhinus chocoensis collected byWEPR and RAB in San Antonio Farm (voucher number MIZI2012397). (Table 1). Based on the P. chocoensis vouchers deposited Choco-Darien ecoregion were originally settled in the in MECN, QCAZ, TTU, and on our record, we propose that Esmeraldas, Manabí, Santo Domingo de los Tsáchilas, Los the new species distribution extends to Santo Domingo Rios, Western Pichincha and Eastern Guayas Provinces de los Tsáchilas province (Fig. 2). Furthermore, according (CEPF, 2005), so a record of endemic Chocoan species to Burneo & Tirira (2014), it may extend to the Los Rios was to be expected in any locality of these provinces.

Pleistocene climatic fluctuations promoted alternative evolutionary histories in Phytelephas aequatorialis, an endemic palm from western Ecuador
<p class="CxSpFirst"><b>Aim: </b>Pleistocene (2.58 Ma – 11.7 ka) climatic fluctuations have shaped intraspecific genetic patterns worldwide; however, their manifestation in many regions remains unknown. In order to determine the impact of Pleistocene climatic fluctuations on the tropical rain forests of western Ecuador, we explored the evolutionary history of the endemic palm <i>Phytelephas aequatorialis</i>.</p> <p class="CxSpMiddle"><b>Location: </b>Western Ecuador, northwestern South America.</p> <p class="CxSpMiddle"><b>Taxon: </b><i>Phytelephas aequatorialis </i>(Arecaceae).</p> <p class="CxSpMiddle"><b>Methods:</b> 176 nuclear genes were sequenced in 91 individuals for phylogenomic and population structure analyses. The time of divergence between identified genetic lineages was estimated using a coalescent phylogenomic analysis. Paleoecological niche modelling analyses were performed to determine areas of historical climatic suitability since the Last Glacial Maximum (LGM; 22 ka) that potentially acted as forest refugia during the Pleistocene. A Wilcoxon test and Pearson correlations were used to explore how current levels of genetic diversity (<i>Hs</i>) have been shaped by several paleoclimatic and geographic factors.</p> <p class="CxSpMiddle"><b>Results:</b> Phylogenomic and population structure analyses revealed two genetic lineages with a north-south distribution, which diverged 1.14 Ma during the Pleistocene. Two potential Pleistocene refugia were identified in the Pacific coast of Ecuador and in the Andean foothills of southwestern Ecuador, whose distribution agrees with the spatial location of the two lineages. Within the Andean foothills, <i>Hs</i> was lower for the southern lineage than for the northern lineage. <i>Hs</i> significantly increased with decreasing latitude within the whole species distribution.</p> <p class="CxSpMiddle"><b>Main conclusions: </b>Pleistocene climatic fluctuations promoted intraspecific divergence in <i>P. aequatorialis </i>within the rain forests of western Ecuador. The Andean foothills of southwestern Ecuador could be an important spot for rain forest evolution because they potentially remained climatically suitable through the Pleistocene. Lower genetic diversity in the southern lineage, which apparently remained isolated in the Andean foothills during glacial cycles, adds evidence to the presence of a forest refugium in southwestern Ecuador. The geographic pattern in genetic diversity suggests that <i>P. aequatorialis </i>colonized western Ecuador from the north. This study supports the role of Pleistocene climatic fluctuations in promoting intraspecific divergence, and for the first time, we show their impact west of the Andes.</p>
