Accounting for individual-specific variation in habitat-selection studies: Efficient estimation of mixed-effects models using Bayesian or frequentist computation
Muff, Stefanie; Signer, Johannes; Fieberg, John (Journal article; Peer reviewed, 2019)1. Popular frameworks for studying habitat selection include resource‐selection functions (RSFs) and step‐selection functions (SSFs), estimated using logistic and conditional logistic regression, respectively. Both frameworks ... -
Animal models with group-specific additive genetic variances: extending genetic group models
Muff, Stefanie; Niskanen, Alina Katariina; Saatoglu, Dilan; Keller, Lukas; Jensen, Henrik (Journal article; Peer reviewed, 2019)Background The animal model is a key tool in quantitative genetics and has been used extensively to estimate fundamental parameters, such as additive genetic variance or heritability. An implicit assumption of animal ... -
Bias away from the Null due to miscounted outcomes? A case study on the TORCH trial
Muff, Stefanie; Puhan, Milo A.; Held, Leonhard (Journal article; Peer reviewed, 2018)Count outcomes occur in virtually all disciplines, such as medicine, epidemiology or biology, but they often contain error. Recently, it has been shown that self-reported numbers of exacerbations of Chronic Obstructive ... -
Endotype-Phenotype Patterns in Meniere’s Disease Based on Gadolinium-Enhanced MRI of the Vestibular Aqueduct
Bächinger, D.; Brühlmann, C.; Honegger, T.; Michalopoulou, E.; Monge Naldi, A.; Wettstein, V.G.; Muff, Stefanie; Schuknecht, B.; Eckhard, A.H. (Journal article; Peer reviewed, 2019)Two histopathological subtypes of Meniere's disease (MD) were recently described in a human post-mortem pathology study. The first subtype demonstrated a degenerating distal endolymphatic sac (ES) in the affected inner ear ... -
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 ... -
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 ... -
Riparian vegetation provides crucial shelter for resting otters in a human-dominated landscape
Weinberger, Irene; Muff, Stefanie; Kranz, Andreas; Bontadina, Fabio (Journal article; Peer reviewed, 2019)The riparian vegetation belt is one of the few remaining structures that provide coverage for wildlife in many anthropogenic landscapes. It provides shelter for many species and functions as corridors for dispersal. However, ... -
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, ...
