“…Clade II (shown in green, Fig. 3), has one branch that contains Haplotypes 10-19 of A. lilljeborgi from Brazil (these are deposited as A. tonsa in GenBank, but see correction by Gomes et al 2018 and discussion in present study) that is sister to a branch that contains Haplotypes 1 and 20-24 from Port Mansfield, Texas GOM.

“…Many other studies not only suggest that A. tonsa is likely a cryptic species complex, but also highlight several instances of misidentification and paraphyly (da Costa et al 2011;Milligan et al 2011;Blanco-Bercial et al 2014;da Costa et al 2014;Gomes et al 2018). In Brazil, da Costa et al (2014), identified three unique lineages of A. tonsa, also based on mtCOI sequences.…”

“…In Brazil, da Costa et al (2014), identified three unique lineages of A. tonsa, also based on mtCOI sequences. Later, Gomes et al (2018) demonstrate that two of the three lineages identified by da Costa et al (2014) likely belong to a different species, Acartia lilljeborgi Giesbrecht, 1889. They provide morphological and genetic evidence to make this assertion.…”

“…To reconcile the taxonomic issues with A. tonsa noted from previous research (e.g., Blanco-Bercial et al 2014;Gomes et al 2018;Milligan et al 2011), all A. tonsa haplotypes were aligned with additional sequences of mtCOI from all other species of Acartia available in GenBank with MUSCLE v3.8 (Supplemental alignment text file). This multi-species alignment was used in phylogenetic analyses using maximum-likelihood (ML) and Bayesian methods.…”

“…Acartia tonsa Dana, 1849, is a calanoid copepod (Copepoda:Calanoida) in the family Acartiidae that is commonly found in coastal estuaries. Acartia tonsa is one of the most abundant and well-studied copepods in the world (Caudill and Bucklin 2004;Hare 2008, 2011;da Costa et al 2011;da Costa et al 2014;Zhou et al 2016;Werbrouck et al 2016;Minh et al 2017;Øie et al 2017;Rahlff et al 2017;Franco et al 2017;Jepsen et al 2017;Pavlaki et al 2017;Krause et al 2017;Plough et al 2018;Gomes et al 2018;Sasaki and Dam 2019) with a global distribution along the coasts of the Indo-Pacific and Atlantic (Mauchline et al 1998). It is often the dominant copepod species in estuaries playing a vital role in the trophic dynamics of these ecosystems as the main consumer of phytoplankton and the main food source for varied fish species (Mauchline et al 1998).…”

The calanoid copepod, Acartia tonsa Dana, 1849 is one of the most abundant and well-studied estuarian species with a worldwide distribution. In this research, we use the mitochondrial cytochrome oxidase subunit I gene to study the phylogeography of A. tonsa by analyzing sequences from specimens collected in the western Gulf of Mexico (GOM) along with all sequences from previous research. We reconstruct the phylogeny for the genus Acartia Dana, 1846 and highlight numerous potential misidentifications of Acartia species deposited in GenBank. The incorrect taxonomy assigned to some of these sequences results in apparently paraphyletic relationships. This study demonstrates that A. tonsa is a species complex with multiple, deeply diverging, lineages of varying geographic affinities. Multiple new lineages are found in the Texas GOM that is basal to northwestern Atlantic lineages with phylogenetic connectivity also observed between Brazil and the Texas GOM. Results show two major phylogeographic breaks in the North American continent, one at the border between the Gulf of Mexico and the Northwest Atlantic, and the other at about 35°N. One of the major clades in the A. tonsa species complex shows a clear pattern of divergence that follows the prevailing currents. Within this clade, older lineages are found in the western GOM while newer lineages are found in the eastern GOM and the southern coast of the northwest Atlantic, with the youngest lineages diversifying in the north. The results show that A. tonsa can be used as a model species for observing phylogeographical structuring of coastal plankton along the American continent.

The loss of biodiversity in marine populations is one of the consequences of the increased events of extreme environmental conditions in the oceans, which can condition the persistence of populations to future scenarios of climate change. Therefore, it is extremely necessary to explore and monitor the genetic diversity of natural populations. In the Southeast Pacific Ocean (SEPO), specifically on the coast of Chile, the presence of the copepod Acartia tonsa has been indicated solely using morphological evidence, due to the absence of genetic information. In the present work, the genetic diversity, population structure and phylogenetic position within the genus Acartia, of populations identified morphologically as A. tonsa, was evaluated by amplification of the mitochondrial cytochrome c oxidase subunit I and nuclear marker 18 s. Our results showed that the populations identified as A. tonsa correspond to a new monophyletic group endemic to SEPO (GMYC = 1.00; PTP = 0.95). The populations showed moderate to high genetic diversity with an incipient structuring between populations and biogeographic zones. Our results suggest that despite the homogenizing effect of the Humboldt Current, isolation by distance and contrasting environmental conditions at different geographic scales have an important influence on the genetic diversity of zooplankton in the SEPO region.
