Development of eDNA Protocols for Detection of Endangered White Sturgeon (Acipenser transmontanus) in the Wild

open access: yesEnvironmental DNA, Volume 6, Issue 5, September–October 2024.
Sturgeons are the world's most threatened group of species, with all 27 species in the order Acipenseriformes (sturgeons and paddlefishes) having populations listed from vulnerable to critically endangered. Understanding their distribution and habitat use is essential for conservation efforts.

Genetics and phylogeny of genus Coilia in China based on AFLP markers [PDF]

open access: yes, 2010
The taxonomy of Coilia has been extensively studied in China, and yet phylogenetic relationships among component taxa remain controversial. We used a PCR-based fingerprinting technique, amplified fragment length polymorphism (AFLP) to characterize and ...

The fate of the duplicated androgen receptor in fishes: a late neofunctionalization event?

open access: yesBMC Evolutionary Biology, 2008
Background Based on the observation of an increased number of paralogous genes in teleost fishes compared with other vertebrates and on the conserved synteny between duplicated copies, it has been shown that a whole genome duplication (WGD) occurred ...

Multiple source genes of HAmo SINE actively expanded and ongoing retroposition in cyprinid genomes relying on its partner LINE

open access: yesBMC Evolutionary Biology, 2010
Background We recently characterized HAmo SINE and its partner LINE in silver carp and bighead carp based on hybridization capture of repetitive elements from digested genomic DNA in solution using a bead-probe 1.

Initial salinity tolerance and ion-osmotic parameters in juvenile Russian sturgeon, Acipenser gueldenstaedtii, Brandt, 1833 [PDF]

open access: yes, 2011
The salinity tolerance, hematological and hydromineral regulation capabilities of juvenile Russian sturgeon (Acipenser gueldenstaedtii) were investigated in different ages and sizes in freshwater (FW: 0.05) but differed in experimental media (p0.05 ...

Cloning and sequence analysis of Sox genes in a tetraploid cyprinid fish, Tor douronensis [PDF]

open access: yes, 2008
A PCR survey for Sox genes in a young tetraploid fish Tor douronensis (Teleostei: Cyprinidae) was performed to access the evolutionary fates of important functional genes after genome duplication caused by polyploidization event.

CLOFFAR - update 1 - supplement to Checklist of the Freshwater Fishes of Argentina [PDF]

open access: yes, 2015
Despite the fact that this first update of CLOFFAR contains 15 changes, the number of species has increased by only 4. The main driver for the recent changes is the paper of Thomaz et al., proposing 8 new combinations for stevardiine characiforms.
