Longest documented coastal migrations of shortnose sturgeon

open access: yesJournal of Fish Biology, EarlyView.
Abstract The shortnose sturgeon (SNS; Acipenser brevirostrum) is a United States federally endangered diadromous species. Although SNS spend much of their time in riverine habitat, inter‐river migrations have been documented in northern populations.

Long Distance Migration of Beluga (Huso huso) and Stellate Sturgeon (Acipenser stellatus) in Lower Danube River in Relation with Iron Gate II Dam

open access: yesBulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca. Animal Science and Biotechnologies, 2018
Construction of the dams in Lower Danube River (LDR- rkm 0 Sulina – rkm 1075 Baziasi) without fish passages, as well as illegal fishery and river bottom modification due to navigation had negative impact on sturgeon’s populations.

Short communication: Study on heavy metals (Chromium, Cadmium, Cobalt and Lead) concentration in three pelagic species of kilka (Genus Clupeonella) in the southern Caspian Sea [PDF]

open access: yes, 2016
Environmental pollution by heavy metals has been a matter of growing concern over the last decades. Heavy metals are toxic and tend to accumulate in living organisms.

Human Impacts on Great Lakes Walleye Sander vitreus Structure, Diversity and Local Adaptation

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Artificial propagation and wild release may influence the genetic integrity of wild populations. This practice has been prevalent in fisheries for centuries and is often termed ‘stocking’. In the Laurentian Great Lakes (Great Lakes here‐on), walleye populations faced declines from the 1950s to the 1970s, prompting extensive stocking efforts ...

Application of microsatellite markers to determine populations of the Persian sturgeon (Acipenser persicus) in the south of Caspian Sea [PDF]

open access: yes, 2011
The objective of this study was to analyse the population genetic structure of the Persian sturgeon (Acipenser persicus) in Sefidrud and Gorganrud rivers watershed based on the characterization of microsatellite markers during 2006 - 2008. 100 samples of

Mechanical shock during egg de-adhesion and post-ovulatory ageing contribute to spontaneous autopolyploidy in white sturgeon culture (Acipenser transmontanus) [PDF]

open access: yes, 2020
Spontaneous autopolyploidy, a 1.5x increase in genome size resulting from second polar body retention after fertilization, has been documented in cultured sturgeons, with the proportion of spontaneous autopolyploid progeny ranging widely among maternal ...

Genome Architecture and Speciation in Plants and Animals

open access: yesMolecular Ecology, EarlyView.
ABSTRACT There have been numerous treatments of specific topics in speciation, but surprisingly few papers have compared patterns and processes of speciation across different organismal groups. In this review, we partially address this gap by asking how variation in genome architecture impacts speciation across the plant and animal kingdoms.
