Phylogeographical analysis reveals multiple conservation units in brook lampreys Lampetra planeri of Portuguese streams.
The populations of brook lamprey Lampetra planeri of Portuguese Rivers were analysed phylogeographically using a fragment of 644 bp of the mitochondrial control region of 158 individuals from six populations. Samples representing L. planeri and migratory lampreys Lampetra fluviatilis of rivers draining to the North Sea and the Baltic Sea were also included to assess the relationships of Portugu...
متن کاملThree new cryptic species of the lamprey genus Lampetra Bonnaterre, 1788 (Petromyzontiformes: Petromyzontidae) from the Iberian Peninsula
The Iberian Peninsula is a repository for biodiversity, presenting high levels of endemism in both plants and animals. In this peninsular region, brook lampreys confined to small, isolated river basins evolved in allopatry giving rise to evolutionary lineages, as revealed by mitochondrial DNA markers. For a better understanding of the taxonomic status and relationships of Iberian populations of...
متن کاملThe Sea Lamprey Petromyzon Marinus (l.), River Lamprey Lampetra Fluviatilis (l.) and Brook Lamprey Lampetra Planeri (bloch) in Ireland: General Biology, Ecology, Distribution and Status with Recommendations for Conservation
Three lamprey species occur in Ireland: sea lamprey, Petromyzon marinus (L.), river lamprey, Lampetra fluviatilis (L.) and brook lamprey, Lampetra planeri (Bloch). All three species are listed under Annex II of the EU Habitats Directive (Directive 92/43/EEC), thereby requiring member states to designate Special Areas of Conservation (SACs) for their protection. The juvenile or ammocoete stages ...
متن کاملStrong genome-wide divergence between sympatric European river and brook lampreys
Lampreys, together with hagfishes, are the only extant representatives of jawless vertebrates and thus of prime interest for the study of vertebrate evolution [1]. Most lamprey genera occur in two forms with divergent life histories: a parasitic, anadromous and a non-parasitic, freshwater resident form [2-8]. The taxonomic status of such 'paired species' is disputed, however. While indistinguis...
متن کاملPCNA immunoreactivity revealing normal proliferative activity in the brain of adult Lampetra planeri (Bloch, 1784).
It is now well known that the Teleosts among Osteichthyes, Urodele and Anuran Amphibians, Lacertilian Reptiles possess encephalic natural proliferative activities even into adulthood, as demonstrated by a great number of researches performed both under normal and various experimental conditions. Few years ago we have undertaken in adult heterothermic vertebrates a reappraisal on spontaneous cer...
