Detection of lamprey in Southernmost South America by environmental DNA (eDNA) and molecular evidence for a new species
- Biology, Environmental SciencePolar Biology
The first report on the distribution of lamprey at the extreme south of Patagonia is provided and the occurrence of a new lamprey species is suggested, suggesting that the Argentinean lamprey corresponds to a new specific taxon that could represent a new monotypic genus in Geotriidae.

The female Lamprey has been recorded to give birth to eight babies in captivity, three of which have been confirmed to be females and the other three to be males.
Revalidation of the Argentinian pouched lamprey Geotria macrostoma (Burmeister, 1868) with molecular and morphological evidence
- BiologyPloS one
The results indicate that the Argentinian pouched lamprey, found along a broad latitudinal gradient on the south-west Atlantic coast of South America, should be named as Geotria macrostoma (Burmeister, 1868), returning to its earliest valid designation in Argentina.
The complete mitogenome of two Australian lampreys: mordacia mordax and mordacia praecox
The recovered topology strongly supported the hypothesis that lampreys separated from hagfishes about 409 MYA, and that lamprey divergence involved the early radiation of Mordaciidae followed by the monophyletic divergence of Geotriidae plus Petromyzontidae about 85 MYA.
The sea lamprey Petromyzon marinus: a model for evolutionary and developmental biology.
- Biology, Environmental ScienceCold Spring Harbor protocols
With the establishment of techniques for the extended maintenance and spawning of lampreys in the laboratory, the sequencing of the lamprey genome, and the adaptation and optimization of many established molecular biology and histochemistry techniques for use in this species, P. marinus is poised to become an evolutionary developmental model of choice.
The gular pouch in northern hemisphere parasitic lampreys (Petromyzontidae)
- Environmental Science
The hypothesis is that these lipids act as an energy source to sustain these two anadromous species during their protracted spawning migration, as the two lumen gular pouch, interpreted as the derived condition, identifies a major clade of northern-hemisphere lam- preys.

A REVIEW OF THE ECOLOGY AND DISTRIBUTION OF THREE LAMPREY SPECIES, LAMPETRA FLUVIATILIS (L.), LAMPETRA PLANERI (BLOCH) AND PETROMYZON MARINUS (L.): A CONTEXT FOR CONSERVATION AND BIODIVERSITY CONSIDERATIONS IN IRELAND
- Environmental Science
An extensive European and North American literature is reviewed to provide a detailed and comparative account of lamprey ecology, particularly those riverine stages most likely to be affected by human activity, and points to those areas in which more information is required to form a basis for decision-making with regard to conservation requirements for these species in Ireland.
Phylogeny of the lamprey genus Lampetra inferred from mitochondrial cytochrome b and ND3 gene sequences
Mitochrondrial DNA analysis resolved many previously unanswered questions concerning the phylogeny of the lamprey genus Lampetra (comprising the subgenera Entosphenus, Lethenteron, and Lampetras) using rates of molecular evolution estimated in other fish taxa.
The taxonomy, phylogeny and distribution of lampreys
The phylogenetic relationships of the lampreys were similar in most respects to those obtained by subjecting molecular data for those species to Bayesian analyses, however, in contrast to the results of morphological analyses, the genera Eudontomyzon and Lampetra were not monophyletic when using molecular analyses.
