Download or read book Mechanisms Driving Karyotype Evolution and Genomic Architecture written by Aurora Ruiz-Herrera and published by MDPI. This book was released on 2021-08-31 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding of the origin of species and their adaptability to new environments is one of the main questions in biology. This is fueled by the ongoing debate on species concepts and facilitated by the availability of an unprecedented large number of genomic resources. Genomes are organized into chromosomes, where significant variations in number and morphology are observed among species due to large-scale structural variants such as inversions, translocations, fusions, and fissions. This genomic reshuffling provides, in the long term, new chromosomal forms on which natural selection can act upon, contributing to the origin of biodiversity. This book contains mainly articles, reviews, and an opinion piece that explore numerous aspects of genome plasticity among taxa that will help in understanding the dynamics of genome composition, the evolutionary relationships between species and, in the long run, speciation.

This book was released on 2014-03-30 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of molecular methods, such as the detection of environmental deoxyribonucleic acid (eDNA), have become an increasingly popular tool in surveillance programs that monitor for the presence of invasive species in aquatic systems. One early application of these methods in aquatic systems was surveillance for DNA of Asian carps (specifically bighead carp Hypophthalmichthys nobilis and silver carp H. molitrix) in water samples taken from the Chicago Area Waterway System (CAWS; Jerde et al. 2011). Analysis of water samples from the CAWS to detect DNA of Asian carps has since been integrated into the Asian carp monitoring program managed by the Monitoring and Response Work Group, an interagency group established by the Asian Carp Regional Coordinating Committee. The U.S. Army Corps of Engineers (USACE) is presently responsible for the analysis of DNA in samples taken from the CAWS and has led the development and refinement of the methods and procedures used to process environmental samples to detect Asian carp DNA. Those methods are specified within the USACE “Quality Assurance Project Plan” or QAPP (USACE 2012).

Book Synopsis Evaluation of Upstream Passage and Associated Movement Patterns of Adult Bigheaded Carp (Hypophthalmichthys Nobilis and H. Molitrix) at a Gated Dam on the Illinois River by : Matthew V. Lubejko

Molitrix) at a Gated Dam on the Illinois River written by Matthew V. Lubejko and published by . This book was released on 2016 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive bighead carp (Hypophthalmichthys nobilis) and silver carp (H. molitrix), hereafter, bigheaded carp, pose a major threat to the Great Lakes ecosystem as they advance toward Lake Michigan via the Illinois River. However, a series of navigation dams may deter their upstream movement. Starved Rock Lock and Dam (SRLD) is the most downstream gated dam on the Illinois River, therefore presenting the first navigation challenge for upstream migrating bigheaded carp. Before 2015, five acoustic receivers near SRLD detected successful upstream passage of only two of 900 tagged bigheaded carp. I further investigated the permeability of SRLD to bigheaded carp migration as a function of temperature, gage height, and dam operation. In 2015, I added 12 receivers around SRLD and acoustically tagged an additional 118 bigheaded carp downstream of SRLD. I also investigated the timing of bigheaded carp arriving downstream of SRLD using a generalized linear model. The explanatory variables influencing bigheaded carp arrival were average water temperature, average tailwater elevation, and the change in average water temperature. During 2015-2016, acoustic receivers recorded a total of 11 upstream passage events through SRLD, with nine through the dam gates, one through the lock chamber, and one undetermined. Passage through the dam gates occurred most frequently at high water levels when the dam gates were completely out of the water. The probability of upstream migrating bigheaded carp approaching SRLD was positively correlated with rising temperature and high gage. No upstream migrants approached SRLD between mid-September and late March. Overall, dam gates were more susceptible to upstream passage than the lock chamber, and environmental factors accurately predicted the arrival of bigheaded carp at SRLD. Modifying gate use during times of bigheaded carp arrival will likely prevent upstream passage through SRLD and other lock and dam structures.

Book Synopsis Environmental DNA Detection and Population Genetic Patterns of Native and Invasive Great Lakes Fishes by : Matthew R. Snyder

This book was released on 2019 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive species are one of the top threats to native biodiversity. Their population genetics and genomics can be useful in control and management of invasive species and can be regarded as accidental evolutionary experiments. Here, in a temporal study of the high impact invasive round goby Neogobius melanostomus in the Laurentian Great Lakes, the ability of invasion genetics to track sources and temporal changes in population structure was demonstrated. We tested for three possible alternative temporal patterns in population genetic diversity over time - termed the `genetic stasis', `supplementation', and `replacement' hypotheses. `Genetic stasis' or no change in allelic composition over time could be caused by a large number of introduced propagules that possibly possess all (or most) of the diversity present in the native source, or by a density dependent process circumventing the establishment of later arrivals. Alternatively, there may be `genetic supplementation' in which populations that experienced an initial founder effect then gain diversity over time. Finally, `replacement' of all or some of the initial founding genetic diversity could result when the early arrivals are the best dispersers, followed by those that are better competitors. Results showed that near the site of initial establishment (the invasion core), high genetic diversity due to a large number of introduced individuals precluded significant changes in allelic composition over time. Further from the invasion core, some slight changes in genetic diversity occurred soon after population establishment. Results supported `genetic stasis' and the founder takes all hypothesis. Due to the territoriality of adult round gobies, it is possible that a density dependent process circumvented establishment of later arrivals. Additional introductions from separate native sources were implicated in some areas of the invasion. Detection of newly introduced species before they can become established and characterizing native community composition are top concerns of management agencies. Metabarcode environmental (e)DNA assays are non-invasive sampling tools for detecting species. Targeted and general metabarcode assays and an associated custom library preparation and bioinformatic pipeline that reduce error were designed and tested. This protocol discerned 100% of species present in electrofishing surveys in the Maumee River from just six water samples. Four 1L water samples in the Maumee River were sufficient to identify 88% of species present in concomitant electrofishing surveys and 73% of those in a much larger effort (44 sampling events in 22 sites). Proportions of species-specific high-throughput sequencing reads were weakly correlated with taxa assessed using morphological surveys. Our method identified more invasive species in more samples than did morphological sampling. Haplotypic diversity discerned with metabarcode assays significantly differed from that determined with traditional population genetic data collection. The protocol increased confidence in metabarcode surveys by removing cross-contamination, index-hops (sequence to sample mis-assignment, leading to false positives), and sequencing error and achieved a high detection efficiency. To evaluate the utility of this approach, the protocol was applied to potential retail sources of invasive species in the Great Lakes, including bait and pond stores. Metabarcode assays found a much greater number of stores with illegal native and invasive species compared to morphological sampling. These included juveniles of valuable fishery species, such as walleye Sander vitreus and yellow perch Perca flavescens, and unestablished, potentially high impact invasive species, including the Eurasian ruffe Gymnocephalus cernua, Eurasian ide Leuciscus idus, and silver Hypophthalmichthys molitrix and bighead H. nobilis carps. Presence of illegal species was unrelated to retailer supply chains. Surveys showed that bait dumping is common among anglers in the Great Lakes. There appears to be serious risk of introduction of non-native species via this vector.

Book Synopsis Genetic Population Structure of the Round Whitefish (Prosopium Cylindraceum) in North America by : Thomas David Morgan

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The round whitefish (Prosopium cylindraceum) is an understudied species of freshwater fish found throughout northern North America and eastern Eurasia. Little is known about the ecology or population genetics of this species. Round whitefish are sensitive to environmental disturbance and have declined in regions of eastern North America, prompting interest in their conservation and management. Understanding the population genetics and phylogeography of round whitefish will inform planning for this species. I genetically characterized round whitefish from 16 locations across North America, and one site in eastern Russia, using microsatellites, mtDNA sequencing, and thousands of SNP loci using a nextRAD approach. I determined phylogeographic and population genetic relationships across sites in Alaska, Yukon, and Northwest Territories as well as the Laurentian Great Lakes region. Genetic analyses resolved strong delineation between eastern and western populations of round whitefish, indicating that they originated from separate glacial refugia. Analyses of regional relationships highlighted the importance of Lake Huron as a source for round whitefish populations, and Lake Ontario as being disjunct from the other Great Lakes. Populations in Alaska and the Yukon showed evidence of historical gene flow, with contemporary patterns linked to the connectivity of river basins in that region. I conclude that round whitefish population structure exists on multiple spatial scales in North America reflecting the deeper phylogenetic relationships of Pleistocene glacial lineages, and shallower divergences reflecting contemporary connectivity due to hydrology. Management of round whitefish needs to consider these major scales by recognizing separate Designatable Units for eastern and western glacial lineages, and appropriate Management Units based on contemporary connectivity. Isolated populations in disturbed areas, such as those in Lake Ontario, require particular attention because of the unlikelihood of rescue dispersal. Further study of this species is warranted to determine its status in Canada, and further identify isolated or sensitive populations.
