Article Synopsis
- Understanding eco-evolutionary feedbacks is crucial as climate change affects global biodiversity, particularly during species range shifts, with two forms of expansion: "pulled" from low-density populations and "pushed" from high-density populations.
- Research on the owl limpet (Lottia gigantea) during marine heatwaves showed that its poleward expansion was characterized by low genomic differentiation between core and leading-edge populations, indicating a "pushed" wave expansion.
- The study highlights that extreme climatic events can enhance range expansions and adaptive potential, but trailing-edge populations face challenges due to local selection, limited gene flow, and differences in climatic stability.
Many sedentary, clonal marine invertebrates compete intensively with conspecifics for habitable space. Allorecognition systems mediate the nature and outcome of these intraspecific competitive interactions, such that the initiation of agonistic behavior and the potential for intergenotypic fusion depend strongly on the relatedness of the contestants. The dependence of these behaviors on relatedness, along with the extraordinary precision with which self can be discriminated from nonself, suggest that allorecognition systems are highly polymorphic genetically.
