Lampreys worldwide face multiple anthropogenic stressors. Several species are 'at-
risk'listed, yet abundance data for most remain insufficient to adequately assess …

Despite their highly conserved body plan and larval stage, adult life history type in lampreys
diverges on two main axes related to migration and feeding. Of the 41–45 recognized …

Some lamprey genera include forms that have significantly different life cycles (the most well
known are the “anadromous” and “resident,” or the “parasitic” and “nonparasitic” forms). The …

Adaptive divergence with gene flow often results in complex patterns of variation within taxa
exhibiting substantial ecological differences among populations. One example where this …

The taxonomy and nomenclature of residential and anadromous forms of lampreys of the
genus Lethenteron are still debated. For this reason, the distribution of mtDNA COI partial …

The present research focuses to examine the meristic and landmark-based morphometric
variations of barred spiny eel Macrognathus pancalus from four populations namely …

In 2019, during spring flood, we collected unusual Lampetra fluviatilis smolts migrating from
a small lake, as part of a multi-year survey in the Chernaya River (Gulf of Finland, Baltic …

The European river lamprey came to the Upper Volga from the Baltic Sea most probably via
a system of shipways developed in the 18th and 19th centuries. The Vyshnii Volochek …

The presence of larvae of the European river lamprey Lampetra fluviatilis was reported for
the first time from in macrobenthic communities of the Neva Bay of the Gulf of Finland (St …

Data on polymorphism (plastic and meristic characters) are obtained for spawners of
resident nonparasitic form of European river lamprey Lampetra fluviatilis from the …
