“…Adults of nonparasitic species do not migrate, are smaller, and have less developed teeth than parasitic lampreys (46). Although the current taxonomy considers all parasitic and nonparasitic lampreys as distinct species, our results, along with those of several previous studies (46)(47)(48)(49)(50)(51)(52)(53), stress the need to revisit lamprey taxonomy.…”

“…Our analysis, based on 174 specimens representing 30 lamprey species that were characterized by ∼650 bp of mtDNA, documents new relationships among lampreys and further corroborates results of other studies. In the most exhaustive previous study, 46 specimens from 23 species had been characterized by 384 bp of mtDNA (48). Lack of divergence between two pairs of lamprey has also been observed at allozymes [Lampetra fluviatilis/Lampetra planeri (49) and Lampetra ayresii /Lampetra richardsoni (50)].…”

Freshwater ecosystems are being heavily exploited and degraded by human activities all over the world, including in North America, where fishes and fisheries are strongly affected. Despite centuries of taxonomic inquiry, problems inherent to species identification continue to hamper the conservation of North American freshwater fishes. Indeed, nearly 10% of species diversity is thought to remain undescribed. To provide an independent calibration of taxonomic uncertainty and to establish a more accessible molecular identification key for its application, we generated a standard reference library of mtDNA sequences (DNA barcodes) derived from expert-identified museum specimens for 752 North American freshwater fish species. This study demonstrates that 90% of known species can be delineated using barcodes. Moreover, it reveals numerous genetic discontinuities indicative of independently evolving lineages within described species, which points to the presence of morphologically cryptic diversity. From the 752 species analyzed, our survey flagged 138 named species that represent as many as 347 candidate species, which suggests a 28% increase in species diversity. In contrast, several species of parasitic and nonparasitic lampreys lack such discontinuity and may represent alternative life history strategies within single species. Therefore, it appears that the current North American freshwater fish taxonomy at the species level significantly conceals diversity in some groups, although artificially creating diversity in others. In addition to providing an easily accessible digital identification system, this study identifies 151 fish species for which taxonomic revision is required.

“…Sequencing reactions were performed in StabVida (Lisbon) on a 3700 ABI DNA sequencer (Applied Biosystems) using the Big Dye terminator DNA sequencing kit (http://www.stabvida.com). A 624-bp fragment of mtDNA from the control region (non-coding region I, according to Blank et al 2008) was sequenced from the four specimens collected (GenBank accession nos. HM245344, HM245345, HM245346, and HM245347).…”

“…However, in the larval and transformer phases, the two Lampetra species are morphologically similar, and neither taxonomic (Hardisty and Potter, 1971;Zanandrea, 1959) nor genetic criteria (Espanhol et al, 2007;Schreiber and Engelhorn, 1998) can separate them in the present state of knowledge. In fact, the taxonomic status of river and brook lampreys is still under debate (Blank et al, 2008;Espanhol et al, 2007;Schreiber and Engelhorn, 1998). The hypothesis of the existence of a single species with two distinct ecotypes that evolve according to the environmental pressures has been proposed by several authors (e.g.…”

a b s t r a c tThe European river lamprey, Lampetra fluviatilis (L.), and the European brook lamprey, Lampetra planeri (Bloch, 1784), are considered highly threatened in Portugal. However, the lack of information about the ecology and distribution of these species poses difficulties to the identification of concrete actions directed to their conservation. A total of 401 sampling sites, randomly distributed throughout the entire Portuguese mainland territory were selected, and Lampetra sp. ammocoetes presence or absence checked with electrofishing. These data, together with 11 macrohabitat predictors, were analyzed using Boosted Regression Trees (BRTs). The BRT models consistently identified five environmental variables as the most important for predicting the distribution of European brook and river lamprey ammocoetes: altitude, distance to coast, sand, maximum temperature of the warmest month and precipitation of the driest month. The relationships of these variables with the species probability of occurrence suggest that lampreys occur in low altitude river stretches (<170 m), relatively close to the coast (<150 km) and with a sandy substrate (>70% sand). In addition, intermediate values of temperature and precipitation were also found to have a positive correlation with the species occurrence. A map with the probability of occurrence of Lampetra sp. in Portugal was generated and stretches of rivers were delimited with different conservation priorities. Rivers classified with the highest level of conservation priority were considered to be proposed as Special Areas of Conservation, under the Natura 2000 Networking Programme.
