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) -
Heritability, selection, and the response to selection in the presence of phenotypic measurement error: effects, cures, and the role of repeated measurements.
Ponzi, Erica; Keller, Lukas F.; Bonnet, Timothee; Muff, Stefanie (Journal article; Peer reviewed, 2018)Quantitative genetic analyses require extensive measurements of phenotypic traits, a task that is often not trivial, especially in wild populations. On top of instrumental measurement error, some traits may undergo transient ... -
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 ... -
Inbreeding reduces long-term growth of Alpine ibex populations
Bozzuto, Claudio; Biebach, Iris; Muff, Stefanie; Ives, Anothony R.; Keller, Lukas F. (Journal article; Peer reviewed, 2019)Many studies document negative inbreeding effects on individuals, and conservation efforts to preserve rare species routinely employ strategies to reduce inbreeding. Despite this, there are few clear examples in nature of ... -
The simulation extrapolation technique meets ecology and evolution: A general and intuitive method to account for measurement error
Ponzi, Erica; Keller, Lukas F.; Muff, Stefanie (Journal article; Peer reviewed, 2019)1. Measurement error and other forms of uncertainty are commonplace in ecology and evolution, and may bias estimates of parameters of interest. Although a variety of approaches to obtain unbiased estimators are available, ...
