Exceptional iron concentrations in larval lampreys (Geotria australis) and the activities of superoxide radical detoxifying enzymes. [PDF]

, 1988
This study aimed to elucidate the way in which larvae of the lamprey Geotria australis counteract the potential problems of the very high concentrations of non-haem iron they contain and thereby avoid the deleterious effects associated with iron overload

Synthesizing beaver coexistence messaging with the capability, opportunity, and motivation behavior model

Conservation Biology, EarlyView.
Abstract In the western United States, conservation practitioners are increasingly working with private landowners to restore habitat for North American beavers (Castor canadensis) and to use nonlethal mitigation techniques when beavers damage crops and infrastructure.

Lampreys have a single gene cluster for the fast skeletal myosin heavy chain gene family. [PDF]

PLoS ONE, 2013
Muscle tissues contain the most classic sarcomeric myosin, called myosin II, which consists of 2 heavy chains (MYHs) and 4 light chains. In the case of humans (tetrapod), a total of 6 fast skeletal-type MYH genes (MYHs) are clustered on a single ...

Lamprey and herring [PDF]

Imago temporis: medium Aevum, 2021
As is common to all periods and cultures, medieval Europe held certain foods in esteem and regarded others as common, even lowly. The social prestige of a particular food item depended on factors such as scarcity, exotic origins, but also actual taste.

An integrated approach to balance freshwater connectivity restoration and invasion risk

Conservation Biology, EarlyView.
Abstract Habitat fragmentation negatively affects many native migratory fish populations. However, this fragmentation can also prevent the spread and establishment of invasive species. We modified the dendritic connectivity index (DCI), a commonly used freshwater connectivity metric, to account for multiple invasive dispersal pathways in estimates of ...

The Forgotten Pink Salmon in the Laurentian Great Lakes: An Unexpected Invasion With Insights for Three Oceans

Fish and Fisheries, EarlyView.
ABSTRACT Introductions of species outside their native range, such as pink salmon (Oncorhynchus gorbuscha) in the Laurentian Great Lakes, can serve as unplanned experiments that provide new insights into ecological adaptation. We synthesize available information on the understudied Great Lakes pink salmon invasion and highlight how this case can inform

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.

Non‐native pink salmon Oncorhynchus gorbuscha carcasses benefit native benthic macroinvertebrates

Journal of Fish Biology, EarlyView.
Abstract The invasion of the North Atlantic by pink salmon Oncorhynchus gorbuscha has raised concerns regarding their impact on coastal rivers. Although the influence of marine‐derived nutrients from returning adult O. gorbuscha on rivers in their native range has received much attention, the ecological consequences of invasive O.

Modeling Population Dynamics and Assessing Ecological Impacts of Lampreys via Sex Ratio Regulation

Applied Sciences
Regulating lamprey populations is crucial for maintaining ecological equilibrium. However, the unique sex determination process of lampreys is constrained by multiple factors, complicating intuitive analysis of population dynamics and their impact on the

CHARACTERIZATION OF LAMPREY FIBRINOPEPTIDES [PDF]

Biochemical Journal, 1965
1. Lamprey fibrinopeptide B is a relatively large peptide made up of about 40 amino acid residues. The peptide is highly electronegative, containing a large number of aspartic acid residues and a tyrosine O-sulphate residue. 2. The amino acid sequence of the first 18 residues from the N-terminal end of fibrinopeptide B has been established.
