Rapid Parallel Adaptation in Distinct Invasions of Ambrosia Artemisiifolia Is Driven by Large-Effect Structural Variants.
Mol Biol Evol
January 2025
School of Biological Sciences, Monash University, Clayton, Victoria 3800, Australia.
When introduced to multiple distinct ranges, invasive species provide a compelling natural experiment for understanding the repeatability of adaptation. Ambrosia artemisiifolia is an invasive, noxious weed, and chief cause of hay fever. Leveraging over 400 whole-genome sequences spanning the native-range in North America and 2 invasions in Europe and Australia, we inferred demographically distinct invasion histories on each continent.

Environmental variation often drives evolutionary processes like population differentiation, local adaptation and speciation. We used genome-scale data to investigate the contribution of environmental variation to evolution of the North Caribbean bark anole (Anolis distichus), a widespread common lizard that exhibits impressive phenotypic variation across varying habitats on the island of Hispaniola. We obtained new double-digest restriction-associated DNA sequence data (ddRADseq) from nearly 200 individuals and used 53 GIS data layers representing a range of environmental variables.

Since the start of the twenty-first century, there has been a notable increase in annual publications focusing on dinosaur reproduction and ontogeny with researchers using these data to address a range of macroevolutionary questions about dinosaurs. Ontogeny, which is closely tied to osteological morphological variation, impacts several key research areas, such as taxonomic diversity, population dynamics, palaeoecology, macroevolution, as well as the physiological and reproductive factors driving ecological success. While these broad studies have significantly advanced our understanding of dinosaur evolution, they have also revealed important challenges and areas needing further investigation.

Department of Biological Sciences, Purdue University, West Lafayette, IN 47907-2054, USA.
Aquatic ecosystems are highly dynamic environments vulnerable to natural and anthropogenic disturbances. High-economic-value fisheries are one of many ecosystem services affected by these disturbances, and it is critical to accurately characterize the genetic diversity and effective population sizes of valuable fish stocks through time. We used genome-wide data to reconstruct the demographic histories of economically important yellow perch () populations.
