Unraveling multipredator impacts in salmon-bearing rivers using quantitative DNA metabarcoding. [PDF]

Ecol Appl
Abstract Ecological impacts of invasive species are mounting as their numbers and geographic extent continue to increase. Across extensive parts of their range, Pacific salmon (Oncorhynchus spp.) smolts face an expanding gauntlet of nonnative predators during their seaward migration.

Development of PCR Blocking Primers Enabling DNA Metabarcoding Analysis of Dietary Composition in Hematophagous Sea Lamprey. [PDF]

Ecol Evol
Eight blocking primers were developed and tested to reduce sea lamprey DNA amplification when using universal 12S rRNA primers for dietary analysis via DNA metabarcoding. These primers effectively suppressed sea lamprey DNA, allowing for clearer detections of host species within digestive tract samples.

First record of Po brook lamprey, Lethenteron zanandreai (Cephalaspidomorphi: Petromyzontiformes: Petromyzontidae), in the Hutovo Blato wetland, Bosnia and Herzegovina [PDF]

Acta Ichthyologica et Piscatoria, 2009
On 14 July 2007 two metamorphosed males of the Po brook lamprey, Lethenteron zanandreai (Vladykov, 1955), were caught in the Hutovo Blato wetland, Neretva River basin (Adriatic Sea watershed) in Bosnia and Herzegovina.

Investigating the Morphogenesis and Replacement of Lamprey Toothlets Using Synchrotron Imaging. [PDF]

J Morphol
Toothlet replacement is a conserved feature in lampreys. We describe the mechanism at tissue level and quantify the determining factors, thus providing the basis for studies into a deep homology of cyclostome toothlets and gnathostome teeth. ABSTRACT Teeth are a key innovation that underpinned the adaptive radiation of jawed vertebrates; however, their

New data regarding the distribution and ichthyocoenological affinities of the Ukrainian brook lamprey, Lampetra (Eudontomyzon) mariae (Cephalaspidomorphi: Petromyzontiformes: Petromyzontidae), in southern Poland [PDF]

Acta Ichthyologica et Piscatoria, 2011
Fifteen new localities of the Ukrainian brook lamprey, Lampetra (Eudontomyzon) mariae, were found within 2008–2010. The majority of them are located in the Nida River drainage. Additionally, the occurrence of that species in the StrwiÄ…ĹĽ River,

Update of Distribution of the Chestnut Lamprey in Arkansas [PDF]

, 2018
Most lamprey species other than sea lampreys have been poorly studied in North America. The chestnut lamprey, Ichthyomyzon castaneus, has a distribution within the Mississippi River and Hudson Bay drainage systems, and the Great Lakes.

Extinction risks and threats facing the freshwater fishes of Britain

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 33, Issue 12, Page 1460-1476, December 2023., 2023
Abstract Extinctions occur naturally in all environments, but rates have accelerated rapidly during the Anthropocene, especially in fresh water. Despite supporting many fish species of conservation importance, there has never been a formal assessment of their extinction risks in Britain, which has impeded their inclusion in relevant legislation and ...

How eDNA data filtration, sequence coverage, and primer selection influence assessment of fish communities in northern temperate lakes

Environmental DNA, Volume 5, Issue 6, Page 1216-1233, November 2023., 2023
We evaluate species’ minimum read proportion threshold, sequence coverage, and primer choice to optimize fish monitoring biodiversity in temperate lakes. Our results suggested: first, using a species minimum read proportion threshold of 0.001 to consider a species as valid limiting false positive; second, sequencing depth had a limited effect on eDNA ...
