Lampreys and spinal cord regeneration: “a very special claim on the interest of zoologists,” 1830s-present

open access: yesFrontiers in Cell and Developmental Biology, 2023
Employing history of science methods, including analyses of the scientific literature, archival documents, and interviews with scientists, this paper presents a history of lampreys in neurobiology from the 1830s to the present. We emphasize the lamprey’s

Attraction of migratory inanga (galaxias maculatus) and koaro (galaxias brevipinnis) juveniles to adult galaxiid odours [PDF]

open access: yes, 2003
The response of migratory galaxiid juveniles, inanga (Galaxias maculatus) and koaro (G. brevipinnis), to the odours of adult galaxiids was tested in a two-choice chamber apparatus. Both conspecific and heterospecific odours were tested. Inanga juveniles

Diel activity of newly metamorphosed juvenile sea lamprey (Petromyzon marinus).

open access: yesPLoS ONE, 2019
Timing of activity, especially for juvenile anadromous fishes undertaking long migrations can be critical for survival. River-resident larval sea lamprey metamorphose into juveniles and migrate from their larval stream habitats in fall through spring ...

Mixtures of Two Bile Alcohol Sulfates Function as a Proximity Pheromone in Sea Lamprey. [PDF]

open access: yesPLoS ONE, 2016
Unique mixtures of pheromone components are commonly identified in insects, and have been shown to increase attractiveness towards conspecifics when reconstructed at the natural ratio released by the signaler. In previous field studies of pheromones that

Contribution of anadromous fish to the diet of European catfish in a large river system [PDF]

open access: yes, 2009
Many anadromous fish species, when migrating from the sea to spawn in fresh waters, can potentially be a valuable prey for larger predatory fish, thereby efficiently linking these two ecosystems. Here, we assess the contribution of anadromous fish to the

3D model of amphioxus steroid receptor complexed with estradiol [PDF]

open access: yes, 2009
The origins of signaling by vertebrate steroids are not fully understood. An important advance was the report that an estrogen-binding steroid receptor [SR] is present in amphioxus, a basal chordate with a similar body plan as vertebrates.

Breakdown products of heme catabolism as senescence index in sea lamprey (Petromyzon marinus Linnaeus, 1758)

open access: yesFrontiers in Marine Science, 2015
Biliverdin and bilirubin are breakdown products of normal heme catabolism, caused by the body's clearance of aged red blood cells which contain hemoglobin.
