Optimization of Parsimonious and Synchronized Discharge and Dissolved Organic Carbon Models Across Catchment Scales

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract The production, transport, loss, and export of dissolved organic carbon (DOC) are closely connected with hydrometeorological drivers. While terrestrial production depends on biogeochemical variables like soil moisture, air temperature, and the contact area between water and organic matter sources, export is determined by water availability and

A Method to Implement Natural Flow Regimes for Regulated Rivers

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract Rivers throughout the world have been dammed for flood control, irrigation, hydropower, and water storage for centuries. Dams service the economic and development needs of societies, but degrade the ecology of rivers. To conserve diminishing aquatic species and their habitats, methods are needed to help managers implement flow releases with ...

Mathematical analysis and simulations of the neural circuit for locomotion in lamprey [PDF]

open access: yes, 2004
We analyze the dynamics of the neural circuit of the lamprey central pattern generator. This analysis provides insight into how neural interactions form oscillators and enable spontaneous oscillations in a network of damped oscillators, which were not ...

Functional Divergence of Glycoprotein Hormone Receptors [PDF]

open access: yes, 2010
Two lamprey glycroprotein hormone receptors (lGpH-R I and II) highly similar with gnathostome GpH-Rs were cloned from sea lamprey testes and thyroid, respectively.

Integrating Sr isotopes, microchemistry, and genetics to reconstruct Salmonidae species and life history

open access: yesArchaeometry, Volume 68, Issue S2, Page S104-S129, May 2026.
Abstract Recent approaches to fisheries research emphasize the importance of the coproduction of knowledge in building resilient and culturally mindful fisheries management frameworks. Despite widespread recognition of the need for Indigenous knowledge and historical reference points as baseline data, archaeological data are rarely included in ...

Dams and Introduced Species Drive Patterns of Environmental Adaptation in an Iconic but Imperiled Coldwater Fish (Brook Trout, Salvelinus fontinalis)

open access: yesEvolutionary Applications, Volume 19, Issue 5, May 2026.
ABSTRACT Freshwater biodiversity is being disproportionately negatively impacted by anthropogenic stressors including climate change, partly due to limited opportunities to seek more favorable conditions compared to marine and terrestrial species. Management plans that maintain locally adapted genotypes, and integrate active management interventions ...

A biologically active peptide in the skin of lampreys (Eudontomyzon danfordi vladykovi). [Translation from: Z.Naturforsch. (B), 26(10), 1021-1023, 1971. ] [PDF]

open access: yes, 1971
In recent years interest in the production and description of kinin-type substances has been greatly intensified. So, for example, bradykinin, phyllokinin, physalaemin, ranatensin and caerulein could be extracted from the skin of amphibians as well as ...

Molecular insights into electroreceptor ribbon synapses from differential gene expression in sturgeon lateral line organs

open access: yesJournal of Anatomy, Volume 248, Issue 5, Page 784-805, May 2026.
The expression of various genes involved in synapse development, stability and/or function was studied in developing mechanosensory neuromasts and electrosensory ampullary organs in sterlet sturgeon. Most were shared, including Slc17a8, Slc1a3 and Nrxn3, but Cbln18 was neuromast‐restricted and Tulp1 was ampullary organ‐restricted.

Spontaneous regeneration of cholecystokinergic reticulospinal axons after a complete spinal cord injury in sea lampreys

open access: yesComputational and Structural Biotechnology Journal
In contrast to humans, lampreys spontaneously recover their swimming capacity after a complete spinal cord injury (SCI). This recovery process involves the regeneration of descending axons.
