Interspecific hybridization of sturgeon species affects differently their gonadal development

open access: yesCzech Journal of Animal Science, 2018
Gonad development in fish is generally assumed to be negatively influenced by interspecific hybridization, resulting in sterility or sub-sterility. However, this is not the case in sturgeons (Acipenseridae), in which fertile hybrids are common.

Bony fish genomes: Status and gaps

open access: yesJournal of Fish Biology, Volume 109, Issue 2, Page 631-649, August 2026.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

Quantifying Morphological Variation in the Ornament and Shape of Dermal Scutes in Sturgeon (Acipenseridae)

open access: yes, 2021
Acipenseridae is a valuable taxonomic family, both ecologically and economically. They are ideal for morphological analysis in part because the family has existed for at least 70 million years, yet has remained largely anatomically static.

Genetic differentiation of spring-spawning and fall-spawning male Atlantic sturgeon in the James River, Virginia.

open access: yesPLoS ONE, 2017
Atlantic sturgeon (Acipenser oxyrinchus oxyrinchus, Acipenseridae) populations are currently at severely depleted levels due to historic overfishing, habitat loss, and pollution.

Complementary taphonomies:Medieval sturgeons from Hungary [PDF]

open access: yes, 2008
This is a review of the Medieval exploitation of Acipenserids in Hungary. Owing to their generally large size and high value these fish have been central to fishing cultures since Prehistory.

Spatiotemporal Assessment of Groundwater Interactions With a Regulated River: A Case Study of the Nechako River, Canada

open access: yesRiver Research and Applications, Volume 42, Issue 6, Page 1172-1187, July 2026.
ABSTRACT Regulated rivers represent complex hydrological systems where groundwater–surface water interactions are governed by natural conditions and human interventions. This study investigates the spatiotemporal dynamics of groundwater–surface water exchanges in the Nechako River, British Columbia (Canada), using numerical simulations.
