Consequences of Single-Locus and Tightly Linked Genomic Architectures for Evolutionary Responses to Environmental Change

Journal of Heredity, Год журнала: 2020, Номер 111(4), С. 319 - 332

Genetic and genomic architectures of traits under selection are key factors influencing evolutionary responses. Yet, knowledge their impacts has been limited by a widespread assumption that most controlled unlinked polygenic architectures. Recent advances in genome sequencing eco-evolutionary modeling unlocking the potential for integrating information into predictions population responses to environmental change. Using simulations, we demonstrate hypothetical single-locus control life history trait produces highly variable unpredictable harvesting-induced evolution relative classically applied multilocus model. Single-locus complex is thought be uncommon, yet blocks linked genes, such as those associated with some types structural variation, have emerged taxonomically phenomena. Inheritance resembles single loci, thus enabling single-locus-like adaptation. number effect sizes, degree linkage among them all occur along continuum. We review how often associated, directly or indirectly, expected from anthropogenic stressors likely play large role adaptation disturbance. suggest using models explore extremes uncertainties when architecture unknown, refining parameters becomes available, explicitly incorporating loci possible. By overestimating complexity (e.g., independent loci) selection, risk underestimating nonlinearity) dynamics.

Evolutionary responses of marine organisms to urbanized seascapes

Evolutionary Applications, Год журнала: 2020, Номер 14(1), С. 210 - 232

Many of the world's major cities are located in coastal zones, resulting urban and industrial impacts on adjacent marine ecosystems. These pressures, which include pollutants, sewage, runoff debris, temperature increases, hardened shorelines/structures, light acoustic pollution, have resulted new evolutionary landscapes for organisms. Marine environmental changes influenced by urbanization may create selective regimes or influence neutral evolution via gene flow partitioning genetic diversity across seascapes. While some such as surfaces, similar to those experienced terrestrial species, others, oxidative stress, specific aquatic environments. Moreover, spatial temporal scales responses differ ocean due extent pressures greater capacity dispersal/gene flow. Here, we present a conceptual framework synthesis current research organisms pressures. We review examine evidence that species adapting, predicted adapt, over rapid time frames. Our findings indicate majority studies, stressors correlated with reduced diversity. Genetic structure is often increased urbanized settings, but artificial structures can also act stepping stones hard-surface specialists, promoting range expansion. Most adaptation comes from studies heritable tolerance pollutants relatively small number species; however, ecotoxicology do not test directly heritability. Finally, highlight gaps our understanding processes environments future address these gaps.

Genetic stock structure of New Zealand fish and the use of genomics in fisheries management: an overview and outlook

New Zealand Journal of Zoology, Год журнала: 2020, Номер 48(1), С. 1 - 31

Опубликована: Июль 13, 2020

Sustainable management of wild fisheries requires accurate delineation reproductively isolated stocks to avoid depletion a commercially and ecologically important resource. However, there is still lack reliable information on stock structure for most fishery species in New Zealand. DNA markers can assist the stocks, but they also provide significant insights into other areas related genetic diversity response pressures. In this review, we first detailed summary population studies Zealand fish species, with particular focus hoki, orange roughy, snapper, ling, blue cod. We find that data uniformly lacking species. then discuss how global shift from low resolution genomics genetics has far reaching consequences sustainable our aquatic resources, by allowing us address multiple pressures are currently facing, introduce some these briefly. conclude emphasising need more systematic holistic approach use management, so best evidence available inform decisions policy makers.

Size does matter — the eco-evolutionary effects of changing body size in fish

Environmental Reviews, Год журнала: 2020, Номер 28(3), С. 311 - 324

Опубликована: Май 4, 2020

Body size acts as a proxy for many fitness-related traits. is also subject to directional selection from various anthropogenic stressors such increasing water temperature, decreasing dissolved oxygen, fisheries, well natural predators. Changes in individual body correlate with changes fecundity, behaviour, and survival can propagate through populations ecosystems by truncating age structures changing predator–prey dynamics. In this review, we will explore the causes consequences of fish light recent literature relevant theories. We investigate central role ecology first discussing main selective agents that influence size: fishing, predation. then impacts these at individual, population, ecosystem levels. Considering relatively high heritability size, discuss how change leave genetic signature population translate evolutionary potential species.
