Evolution 2019: Population Structure, Genetic Diversity, and Genotypic Specificity in Flowering Time of Boston Area Dandelions (Taraxacum sp.)
Who hasn’t picked up a fluffy dandelion, blew a deep breath, and smiled as the seeds fly along on the wind? But did you know that those seeds are possibly clones of the parent plant? Dandelions (Taraxacum sp.) can produce…

Evolution 2019: Do Anoles Adapt to Urbanization in Similar Ways? Maybe.
A major outstanding question in urban evolution (and evolutionary biology in general) is whether adaptation occurs in similar ways in different populations and across species boundaries. In other words, can the common selective pressures of urban environments lead to convergent…

Evolution 2019: Evolutionary Rescue from Extreme Environmental Pollution Enabled by Recent Adaptive Introgression of Highly Advantageous Haplotypes
Humans often drive quick and pronounced changes to the environment. When faced with novel environmental stressors, natural populations must adapt to changing conditions, migrate to a new location to avoid the stressors, or face extinction. Adaptation to stressful environments can…

Evolution 2019: Urban Coyotes are Genetically Distinct from and Less Diverse than Coyotes in Natural Habitats
Habitat fragmentation associated with urbanisation if often thought to limit the movement of mobile species, potentially leading to genetically distinct clusters of individuals across a city. Identifying the landscape features that act as barriers to dispersal and drive population differentiation…

Evolution 2019: Biodiversity and Invaders on Marine Artificial Structures
With increased human movement across the globe comes the increased risk of transporting exotic species, which may establish and disrupt local native communities. In marine environments, boats are frequent vectors for the movement of exotic species, which often get transported…

Evolution 2019: Human Land Use Impacts Gene Flow in the Biodiversity Hotspot Cape Floristic Region, South Africa
During Monday’s poster session at Evolution 2019, I had the chance to talk with Dr. Lindsay Miles (currently a postdoc at the University of Toronto-Mississauga and an editor of this blog) about research she conducted during her PhD at Virginia…

Evolution 2019: Urbanization Drives Evolution of Darwin’s Finches in the Galápagos
Many of us don’t think of the Galápagos as a place that is urbanized, but as we’ve discussed here on Life in the City previously, there is substantial human impact in the archipelago. An estimate from 2012 places the population size…

Evolution 2019: Urban Lizard Morphology Changes After Hurricane Maria
Kevin Aviles-Rodriguez, a contributor here at LITC, studies urban adaptation and behavior of Anolis lizards. Previously, we told you all about Kevin’s research on escape behavior of urban versus forest anoles, which was Kevin’s MS research. During his PhD, Kevin has…
