Parallel polygenic urban adaptation despite high gene flow in a coastal marine invertebrate

Madison L. Armstrong, Katie L. Erickson, Rebecca Hawthorne, Brenda B. Cameron et autres

Abstract Urbanization results in novel environments, offering a unique opportunity to investigate natural selection on small spatiotemporal scales. Although each city is different, geographically distinct cities can in some ways represent evolutionary replicates, allowing for the investigation of parallel and predictable evolutionary …

Developmental and Transcriptomic Responses in Sea Urchin Larvae to an Urban‐Associated Pollutant

Madison L. Armstrong, Rachael A. Bay

ABSTRACT Urban environments provide a unique opportunity to investigate the impacts of novel stressors on organismal performance. Marine intertidal zones exist at the transition from sea to land, where they are exposed to a unique suite of stressors, including those associated with …

Multiple Stressors in the Anthropocene: Urban Evolutionary History Modifies Sensitivity to the Toxic Effects of Crude Oil Exposure in Killifish

Jane Park, Charles A. Brown, Chelsea Hess, Madison L. Armstrong et autres

ABSTRACT Persistence of wild species in human‐altered environments is difficult, in part because challenges to fitness are complex when multiple environmental changes occur simultaneously, which is common in the Anthropocene. This complexity is difficult to conceptualize because the nature of environmental change …

Selection Over Small and Large Spatial Scales in the Face of High Gene Flow

Camille A. Rumberger, Madison L. Armstrong, Rafael A. Ponce, Serena A. Caplins

Local adaptation represents the balance of selection and gene flow. Increasingly, studies find that adaptation can occur on spatial scales much smaller than the scale of dispersal, resulting in balanced polymorphisms within populations. However, microgeographic adaptation might be facilitated or hindered by …

Selection Over Small and Large Spatial Scales in the Face of High Gene Flow

Camille A. Rumberger, Madison L. Armstrong, Martin Jean Kim, J. Andre Melendez et autres

The interaction between selection and gene flow can determine to what degree populations are able to adapt to local environmental conditions. This presents a particular conundrum in marine systems, as many marine species have high dispersal capacity resulting in nearly panmictic populations. …

Identifying drivers of sewage-associated pollutants in pollinators across urban landscapes

Michael F. Meyer, Matthew R. Brousil, Benjamin W. Lee, Madison L. Armstrong et autres

ABSTRACT Human sewage can introduce pollutants into food webs and threaten ecosystem integrity. Among the many sewage-associated pollutants, pharmaceuticals and personal care products (PPCPs) are useful indicators of sewage in ecosystems and can also cause potent ecological consequences even at minute concentrations …
