- Complete mitochondrial genomes of the freshwater mussels Amblema plicata (Say, 1817), Pleurobema oviforme (Conrad, 1834), and Popenaias popeii (Lea, 1857) (Bivalvia: Unionidae: Ambleminae)Publication . Teiga-Teixeira, João; Froufe, Elsa; Gomes-dos-Santos, André; Bogan, Arthur E.; Karatayev, Alexander Y.; Burlakova, Lyubov E.; Aldridge, David C.; Bolotov, Ivan N.; Vikhrev, Ilya V.; Teixeira, Amílcar; Varandas, Simone; Zanatta, David T.; Lopes-Lima, ManuelFreshwater mussels are a critically imperiled group of mollusks that play key ecological roles and provide important services to humans. The Ambleminae is the only subfamily of these mussels, endemic to North America. Complete mitogenomes have only been sequenced for two of five tribes of the subfamily. Pleurobema oviforme, Amblema plicata, and Popenaias popeii each belong to tribes Pleurobemini, Amblemini, and Popenaidini, respectively, and have not had published mitogenomes. Thus, this study aims to present the complete mitogenomes for these species, to provide a phylogeny of the Ambleminae and confirm the gene arrangements with representation from each of its tribes. The newly sequenced mitogenomes range from 15,852 to 15,993 nucleotides, are composed of 13 PCGs, 22 tRNAs, and two rRNAs and all share the same (UF1) gene order.
- The first Margaritiferidae male (M-Type) mitogenome: Mitochondrial gene order as a potential character for determining higher-order phylogeny within Unionida (Bivalvia)Publication . Lopes-Lima, Manuel; Fonseca, Miguel M.; Aldridge, David C.; Bogan, Arthur E.; Gan, Han Ming; Ghamizi, Mohamed; Sousa, Ronaldo; Teixeira, Amílcar; Varandas, Simone; Zanatta, David T.; Zieritz, Alexandra; Froufe, Elsa
- Phylogeny of the most species-rich freshwater bivalve family (Bivalvia: Unionida: Unionidae): defining modern subfamilies and tribesPublication . Lopes-Lima, Manuel; Froufe, Elsa; Do, Van Tu; Ghamizi, Mohamed; Mock, Karen E.; Kebapçi, Ümit; Klishko, Olga; Kovitvadhi, Satit; Kovitvadhi, Uthaiwan; Paulo, Octávio S.; Pfeiffer, John; Raley, Morgan; Riccardi, Nicoletta; Şereflişan, Hülya; Sousa, Ronaldo; Teixeira, Amílcar; Varandas, Simone; Wu, Xiaoping; Zanatta, David T.; Zieritz, Alexandra; Bogan, Arthur E.Freshwater mussels of the order Unionida are key elements of freshwater habitats and are responsible for important ecological functions and services. Unfortunately, these bivalves are among the most threatened freshwater taxa in the world. However, conservation planning and management are hindered by taxonomic problems and a lack of detailed ecological data. This highlights the urgent need for advances in the areas of systematics and evolutionary relationships within the Unionida. This study presents the most comprehensive phylogeny to date of the larger Unionida family, i.e., the Unionidae. The phylogeny is based on a combined dataset of 1032 bp (COI + 28S) of 70 species in 46 genera, with 7 of this genera being sequenced for the first time. The resulting phylogeny divided the Unionidae into 6 supported subfamilies and 18 tribes, three of which are here named for the first time (i.e., Chamberlainiini nomen novum, Cristariini nomen novum and Lanceolariini nomen novum). Molecular analyses were complemented by investigations of selected morphological, anatomical and behavioral characters used in traditional phylogenetic studies. No single morphological, anatomical or behavioral character was diagnostic at the subfamily level and few were useful at the tribe level. However, within subfamilies, many tribes can be recognized based on a subset of these characters. The geographical distribution of each of the subfamilies and tribes is also presented. The present study provides important advances in the systematics of these extraordinary taxa with implications for future ecological and conservation studies.
