Evolutionary biogeography of the reef-building coral genus Galaxea across the Indo-Pacific ocean
<p>Stony corals (Scleractinia) form the basis for some of the most diverse ecosystems on Earth, but we have much to learn about their evolutionary history and systematic relationships. In order to improve our understanding of species in corals, we here investigated phylogenetic relationships between morphologically defined species and genetic lineages in the genus <em>Galaxea</em> (Euphyllidae) using a combined phylogenomic and phylogeographic approach. Previous studies revealed the nominal species <em>G. fascicularis</em> included three genetically well-differentiated lineages (L, S & L+) in the western Pacific, but their distribution and relationship to other species in the genus were unknown. Based on genomic (RAD-seq) and mitochondrial sequence data (non-coding region between <em>cytb</em> and <em>ND2</em>) we investigated whether the morphological taxa represent genetically coherent entities and what is the phylogenetic relationship and spatial distribution of the three lineages of <em>G. fascicularis</em> throughout the observed species range. Using the RAD-seq data, we find that the genus Galaxea is monophyletic and contains three distinct clades: an Indo-Pacific, a Pacific, and a small clade restricted to the Chagos Archipelago. The three lineages of <em>G. fascicularis</em> were associated with different RAD-seq clades, with the 'L' lineage showing some morphological distinction from the other two lineages (larger more asymmetrical polyps). In addition to these, three more genetic lineages in <em>G. fascicularis</em> may be distinguished – a Chagossian, an Ogasawaran, and one from the Indian-Red Sea. Among nominal taxa for which we have multiple samples, <em>G. horrescens</em> was the only monophyletic species. The mitochondrial non-coding region is highly conserved apart from the length polymorphism used to define L, S & L+ lineages and lacks the power to distinguish morphological and genetic groups resolved with genomic RAD-sequencing. The polyphyletic nature of most species warrants a careful examination of the accepted taxonomy of this group with voucher collections and their comparison to type specimens to resolve species boundaries. Further insight to the speciation process in corals will require international cooperation for the sharing of specimens to facilitate scientific discovery.</p>
Population structure and demographic analyses of Acanthocybium solandri from the Indo-Pacific and Atlantic oceans
<p>This repository contains scripts, data and results for a populaton genomics study of genetic structure and demography of wahoo, <em>Acanthocybium solandri</em>, published in <em>Journal of Biogeography:</em></p> <p>Haro-Bilbao et al. (2021) Global connections with some genomic differentiation occur between Indo-Pacific and Atlantic Ocean wahoo, a large circumtropical pelagic fish.</p> <p>In this work, we generated population allele frequencies for wahoo sampled at 11 locations around the globe using a pooled ezRAD approach. Using thousands of genome-wide SNPs, we demonstrated a significant (but subtle) genetic divide between wahoo from the Indo-Pacific and those from the Atlantic. This genetic differentiation likely occurs against a background of high gene glow throughout the evolutionary history of wahoo, as we inferred from demographic analysis of select population pairs within and between oceanic regions.</p> <p>Analyses contained in this repository are for: (1) Filtering pooled ezRAD allele counts (assembled with <em>dDocent </em>and imputed using <em>poolne_estim</em>); (2) Estimation of genetic differentiation among globally sampled wahoo populations; (3) Estimation of site frequency spectra from joint allele frequencies among select population pairs; (4) Inference of demographic parameters (using <i>δaδi</i>); and (5) Generations of demographic simulation summary statistics.</p> <p>Most of the analyses are performed in R and can be run directly from within the repository directory, this includes: allele filtering, estimation of genetic differentiation, estimaiton of site frequency spectra, and generation of demographic summary statistics. Demographic inference using <i>δaδi</i> requires setup of a Unix environment: input data files and execution scripts are provided, but their implementation needs to be customised.</p>

Description and classification of echolocation clicks of Indian Ocean humpback (Sousa plumbea) and Indo-Pacific bottlenose (Tursiops aduncus) dolphins from Menai Bay, Zanzibar, East Africa
<p>Passive acoustic monitoring (PAM) is a powerful method to study the occurrence, movement and behavior of echolocating odontocetes (toothed whales) in the wild. However, in areas occupied by more than one species, echolocation clicks need to be classified into species. The present study investigated whether the echolocation clicks produced by small, at-risk, resident sympatric populations of Indian Ocean humpback dolphin (Sousa plumbea) and Indo-Pacific bottlenose dolphin (Tursiops aduncus) in Menai Bay, Zanzibar, East Africa, could be classified to allow species specific monitoring. Underwater sounds of S. plumbea and T. aduncus groups were recorded using a SoundTrap 202HF in January and June-August 2015. Eight acoustic parameters, i.e. -10 dB duration, peak, centroid, lower -3 and lower -10 dB frequencies, and -3 dB, -10 dB and root-mean-squared bandwidth, were used to describe and compare the two species' echolocation clicks. Statistical analyses showed that S. plumbea clicks had significantly higher peak, centroid, lower -3 and lower -10 dB frequencies compared to T. aduncus, whereas duration and bandwidth parameters were similar for the two species. Random Forest (RF) classifiers were applied to determine parameters that could be used to classify the two species from echolocation clicks and achieved 28.6% and 90.2% correct species classification rates for S. plumbea and T. aduncus, respectively. <a name="_Hlk32088545">Both species were classified at a higher rate than expected at random, however the identified classifiers would only be useful for T. aduncus monitoring.</a> <a name="_Hlk32088580">The frequency and bandwidth parameters provided most power for species classification.</a> <a name="_Hlk32088592">Further study is necessary to identify useful classifiers for S. plumbea.</a> This study represents a first step in acoustic <a name="_Hlk32088605">description </a>and classification of S. plumbea and T. aduncus in the western Indian Ocean region, with potential application for future acoustic monitoring of species-specific temporal and spatial occurrence in these sympatric species.</p>
