1. Molecular analyses reveal the occurrence of three new sympatric lineages of velvet worms (Onychophora: Peripatidae) in the eastern Amazon basin
Abstract In the present study, we investigated the possible existence of new lineages of peripatids through comparisons between known Neotropical species and specimens obtained from two locations in Pará, a state in eastern Brazilian Amazonia using a molecular approach based on sequences of the mtDNA genes COI, 16Sr RNA, and 18S RNA. The analyses included a

2. Presence of two mitochondrial genomes in the mytilid Perumytilus purpuratus: Phylogenetic evidence for doubly uniparental inheritance
This study presents evidence, using sequences of ribosomal 16S and COI mtDNA, for the presence of two mitochondrial genomes in Perumytilus purpuratus. This may be considered evidence of doubly uniparental mtDNA inheritance. The presence of the two types of mitochondrial genomes differentiates females from males. The F genome was found in the somatic and gona

3. Revisão taxonômica dos caranguejos marinhos do gênero Persephona Leach, 1817 (Decapoda, Leucosiidae) / Taxonomic Review of the marine crabs of the genus Persephona Leach, 1817
O gênero Persephona Leach, 1817 é restrito a América e é constituído por dez espécies com ocorrência no Atlântico Ocidental e Pacífico Oriental, estando inserido na subfamília Ebaliinae, a qual não se encontra taxonomicamente bem estabelecida. Ao longo dos anos, este gênero foi alocado em diferentes subfamílias e sua classificação é mal defin

4. Revisão das espécies de Macrobrachium, Bate, 1868, pertencentes ao complexo M. olfersii (Crustacea, Palaemonidae): análises morfológicas e moleculares / Revision of species from Macrobrachium, Bate, 1868, that belonging M. olfersii complex (Crustacea, Palaemonidae): morphologic and molecular analysis.
Pesquisas envolvendo a sistemática e a taxonomia de camarões de água doce do gênero Macrobrachium Bate, 1868 ainda são pouco elucidativas para alguns de seus membros. Este é o caso de Macrobrachium olfersii (Wiegmann, 1836) que ocorre desde o sudeste dos Estados Unidos até o sul do Brasil e é comumente confundido com espécies que ocorrem preferencia

5. Genetic distance between broodstocks of the marine shrimp Litopenaeus vannamei (Decapoda, Penaeidae) by mtDNA analyses
In the constantly growing Brazilian shrimp industry the evaluation of genetic relationships between broodstocks is an useful tool for shrimp culture management programs. We established the genetic relationships between five broodstocks of the white marine shrimp Litopenaeus vannamei (Penaeidae) based on the sequencing of the mtDNA 16S rRNA and cytochrome oxi

6. Relações genéticas entre plantéis de reprodutores do camarão marinho Litopenaeus vannamei, através do seqüenciamento dos genes RNAr 16S e COI do DNAmt.
The evaluation of genetic relationships among broodstocks is a useful tool for culture management programs. In the present work, the relationships amongst four broodstocks of the marine shrimp Litopenaeus vannamei were established based on sequencing of 16S rRNA and COI regions from mtDNA. Farfantepenaeus subtilis was used as outgoup in mtDNA analysis. No di

7. Genes for respiratory chain proteins and ribosomal RNAs are present on a 16-kilobase-pair DNA species from Chlamydomonas reinhardtii mitochondria.
We have used heterologous hybridization and DNA sequence analysis to determine whether the 16-kilobase-pair (kbp) DNA from Chlamydomonas reinhardtii mitochondria is the functional equivalent of mtDNA in other eukaryotes. Restriction fragments corresponding to a continuous internal stretch spanning 75% of the 16-kbp DNA have been cloned and mapped, and region

8. The Mitochondrial Genomes of Two Nematodes, Caenorhabditis Elegans and Ascaris Suum
The nucleotide sequences of the mitochondrial DNA (mtDNA) molecules of two nematodes, Caenorhabditis elegans [13,794 nucleotide pairs (ntp)], and Ascaris suum (14,284 ntp) are presented and compared. Each molecule contains the genes for two ribosomal RNAs (s-rRNA and l-rRNA), 22 transfer RNAs (tRNAs) and 12 proteins, all of which are transcribed in the same
