Shifting Patterns of Nitrogen Excretion and Amino Acid Catabolism Capacity during the Life Cycle of the Sea Lamprey (\u3cem\u3ePetromyzon mariunus\u3c/em\u3e) [PDF]
, 2006 The jawless fish, the sea lamprey (Petromyzon marinus), spends part of its life as a burrow-dwelling, suspension-feeding larva (ammocoete) before undergoing a metamorphosis into a free swimming, parasitic juvenile that feeds on the blood of fishes.

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.ABSTRACT The Mediterranean basin is a hotspot of freshwater endemisms and restricted‐range species, which are among the most threatened worldwide. The Adriatic brook lamprey Lampetra zanandreai is a non‐parasitic, freshwater‐resident lamprey whose core distribution lies in the Po River basin (Northern Italy).

Conservation Science and Practice, 2021 Native lampreys continue to be misunderstood by some citizens in the Pacific Northwest (PNW; USA). This misunderstanding is caused by persistent misperceptions reinforced in media and exacerbated by a long‐running (mid‐1900s to present) and pervasive ...

Icelandic lampreys (Petromyzon marinus): where do they come from? [PDF]
Ichthyological Research, 2011 The recent discovery of sea lamprey wounds on salmonids in Icelandic rivers prompted an investigation on the origin of sea lampreys in Icelandic waters. Using a mitochondrial DNA fragment, the origin of the lampreys examined was assigned to the European stock and not to the North American one.

Water Resources Research, Volume 62, Issue 2, February 2026.Abstract Habitat destruction is a global driver of biodiversity loss. In rivers, damming and river regulation for hydropower have caused extensive loss of high gradient, riffle, rapid and waterfall habitats. Restoring these habitats, which support unique biodiversity, should be an urgent priority, but inadequate documentation hampers evaluation of ...

Journal of Fish Biology, Volume 108, Issue 2, Page 694-706, February 2026.Abstract Lake whitefish are a cold‐water species that holds cultural and economic importance throughout the Great Lakes region. Anthropogenic stressors over the last 60 years (e.g., invasive species, habitat degradation, and pollution) have caused significant declines in their populations.

A Hox regulatory network of hindbrain segmentation is conserved to the base of vertebrates [PDF]
, 2014 A defining feature governing head patterning of jawed vertebrates is a highly conserved gene regulatory network that integrates hindbrain segmentation with segmentally restricted domains of Hox gene expression.
