To re-evaluate the relationships of major bivalve lineages, we amassed detailed morpho-anatomical, ultrastructural and molecular sequence data for a targeted selection exemplar bivalves spanning phylogenetic diversity class. We included 103 species (up to five markers) also analysed subset taxa with four additional nuclear protein-encoding genes. Novel as well historically employed morphological characters were explored, systematically disassembled widely used descriptors such gill stomach...
Abstract Background Since the mid 1990s populations of non-native apple snails (Ampullariidae) have been discovered with increasing frequency in continental United States. Given dramatic effects that introduced had on both natural habitats and agricultural areas Southeast Asia, their introduction to mainland U.S. is cause for concern. We combine phylogenetic analyses mtDNA sequences examination museum collections clarify identities, distributions, geographical origins, histories snails....
Bivalves are an ancient and ubiquitous group of aquatic invertebrates with estimated 10 000-20 000 living species. They economically significant as a human food source, ecologically important given their biomass effects on communities. Their phylogenetic relationships have been studied for decades, unparalleled fossil record extends from the Cambrian to Recent. Nevertheless, robustly supported phylogeny deepest nodes, needed fully exploit bivalves model testing macroevolutionary theories, is...
By combining data from a variety of sources we explore patterns evolution and speciation in Nucella, widely studied genus shallow-water marine neogastropods. We present hypothesis phylogenetic relationships for all the currently recognized species northern hemisphere based on an analysis 718 base pairs nucleotide sequence mitochondrial cytochrome b gene. The order appearance fossil record is congruent with this hypothesis. topology inferred phylogeny coupled ecological, morphological,...
A new species of vermetid gastropod belonging to the genus Novastoa Finlay, 1926, N. rapaitiensis sp. nov., is described from French Polynesia and Great Barrier Reef, based on morpho-anatomical molecular data, increasing recognized extant diversity this five six species. The characterized by largest operculum in date, with a conspicuous spindle-shaped mammilla that readily distinguishes its congeners. Based available members studied populations nov. are interpreted as single species,...
We examined the anatomy of expanding, mature, and senescing leaves tropical plants for presence red pigments: anthocyanins betacyanins. studied 463 species in total, 370 genera, belonging to 94 families. This included 21 from five families Caryophyllales, where betacyanins are basis color. also 14 ferns gymnosperms seven 29 with undersurface coloration at maturity. analyzed 399 angiosperm (74 families) factors (especially developmental evolutionary) influencing anthocyanin production during...
Widespread sampling of vertebrates, which comprise the majority published animal mitochondrial genomes, has led to view that gene rearrangements are relatively rare, and orders typically stable across major taxonomic groups. In contrast, more limited within Phylum Mollusca revealed an unusually high number order arrangements. Here we provide evidence lability molluscan genome extends family level by describing extensive changes have occurred Vermetidae, a sessile marine gastropods radiated...
Abstract Since 1955 snails of the Euglandina rosea species complex and Platydemus manokwari flatworms were widely introduced in attempted biological control giant African ( Lissachatina fulica ) but have been implicated mass extinction Pacific island snails. We review histories 60 introductions their impacts on L. native 1993 there unofficial releases within groups. Only three official P. took place, new populations are being recorded at an increasing rate, probably because accidental...
Although the majority of metazoan mitochondrial genomes (mtDNAs) contain same 37 genes, including 22 encoding transfer RNAs (tRNAs), recognition orthologs is not always straightforward. Here we demonstrate that inferring tRNA among taxa by using anticodon triplets and deduced secondary structure can be misleading: through a process duplication mutation in triplet, remolded leucine (L UUR ) genes have repeatedly taken over role isoaccepting L CUN tRNAs within mtDNA. In present work, data from...
The advent of genomics has fueled optimism for improvement in the reliability and accuracy phylogenetic trees. An implicit assumption is that there will be an inexorable as number genes used increases, this approach necessary because are no identifiable parameters predict performance (Gee, 2003; Rokas et al. 2003). These issues were explored recent article by who investigated signal a sample 106 protein-encoding selected from genomes 8 species yeast. (2003) analyzed these separately,...
Circulating leukocytes are important in dissemination of cytomegalovirus (CMV) infection humans. In the mouse model murine CMV (MCMV), it has been shown that peaks on days 5 to 7 after experimental infection, when 0.01 0.1% circulating contain viral DNA. our laboratory, MCMV DNA was detected by situ hybridization predominantly mononuclear cells day 6 acute infection. Infectious virus recovered from fractions 16 mice compared with polymorphonuclear 4 mice. An eclipse phenomenon noted blood...
Abstract: Genetic analysis of introduced populations, especially in morphologically conservative taxa, can clarify introduction histories, identify management units and source provide a more realistic estimate the frequency successful invasion, suggest strategies for preventing further introductions. In last 7 years, populations swamp eels, referred to Asian genus Monopterus ( Family Synbranchidae) on basis external morphology, have been discovered aquatic habitats near Atlanta, Georgia;...
Latency is essential to the pathogenesis of cytomegalovirus (CMV) infection and disease. A survey mouse organs that might contain latent murine CMV (MCMV) DNA was conducted using nested enzymatic amplification a 200-bp region exon 4 major immediate early gene 1. MCMV detected in diverse including heart, kidney, liver, lung, spleen, brain, salivary glands. The total number which significantly greater mice infected at weeks age (64/70) than 7 (40/69). This phenomenon associated with viral...
Abstract The New Guinea flatworm ( Platydemus manokwari de Beauchamp) (Tricladida: Geoplanidae), recognized in the Global Invasive Species Database as one of 100 worst invasive species, was first observed Florida 2012 and documented 2015. Since that time, P. populations have spread into numerous urban natural environments throughout Florida. Here we report on status 38 conserved native forests (tropical hardwood hammocks) with information their geographic distribution densities Miami Rock...
Identifying natural groups within the caenogastropod family Vermetidae has proven challenging. The sessile lifestyle of vermetids, with associated xenomorphically distorted, overgrown and corroded shells, resulted in a long confused taxonomic history based primarily on adult shell characters. In this study, we use morphological, anatomical molecular data to clarify systematics phylogenetic relationships genus Dendropoma s.l. We assess generic names previously used group for availability...
Piranhas and their relatives have proven to be a challenging group from systematic perspective, with difficulties in identification of species, linking juveniles adults, diagnosis genera, recognition higher-level clades. In this study we add new molecular data consisting three mitochondrial regions for museum vouchered photo-documented representatives the Serrasalmidae. These are combined existing serrasalmid sequences GenBank address species questions within piranhas using parsimony...
Since the 1990s, possibly earlier, large numbers of Asian swamp eels (Synbranchidae: Monopterus spp.), some wild-caught, have been imported live from various countries in Asia and sold ethnic food markets cities throughout USA parts Canada. Such are likely introduction pathway some, perhaps most, five known wild populations present continental United States. This paper presents results a pilot study intended to gather baseline data on occurrence abundance internal macroparasites infecting...
