The More, the Merrier? Membership Expansion and Incumbents' Boundary Work Divergence in the Platformization of Belgian Philanthropy

Journal of Management Studies, EarlyView.
Abstract When actors emerge on the periphery of a field, incumbents either engage in protective boundary work to enforce the field's membership criteria, or opt for membership expansion by adapting these criteria to accommodate peripheral actors. Less explored is the divergence configuration where a minority of incumbents pursue expansion whereas the ...

Phylogenomics of the American robin (Turdus migratorius) reveals hidden lineages and introgression

Journal of Systematics and Evolution, EarlyView.
Phylogenomic analyses of Turdus migratorius uncover four previously unrecognized lineages, including a divergent Baja California lineage (T. m. confinis). The results reveal complex evolutionary relationships that depart from simple models of continuous divergence, supported by evidence of introgression between the Mexican lineage and its previously ...
