Are immigrants outbred and unrelated? Testing fundamental assumptions in a wild metapopulation
Dickel, Lisa; Arcese, Peter; Nietlisbach, Pirmin; Keller, Lukas F.; Jensen, Henrik; Reid, Jane Margaret (Journal article; Peer reviewed, 2021) -
Immigration counter-acts local micro-evolution of a major fitness component: migration-selection balance in free-living song sparrows
Reid, Jane Margaret; Arcese, Peter; Nietlisbach, Pirmin; Wolak, Matthew; Muff, Stefanie; Dickel, Lisa; Keller, Lukas F. (Peer reviewed; Journal article, 2021)Ongoing adaptive evolution, and resulting “evolutionary rescue” of declining populations, requires additive genetic variation in fitness. Such variation can be increased by gene flow resulting from immigration, potentially ... -
Multi-generation genetic and fitness effects of immigration in a natural meta-population of song sparrows (Melospiza melodia)
Dickel, Lisa (Doctoral theses at NTNU;2024:105, Doctoral thesis, 2024)Fragmentation leads to smaller habitat patches and population sizes, endangering population fitness and persistence, including through inbreeding depression and loss of genetic diversity. These effects can be mitigated ...
