Modelling habitat-suitability using museum collections: an example with three sympatric Apodemus species from the Alps

摘要: Aim, Location Although the alpine mouse Apodemus alpicola has been given species status since 1989, no distribution map ever constructed for this endemic rodent in Switzerland. Based on redetermined museum material and using Ecological-Niche Factor Analysis (ENFA), habitat-suitability maps were computed A. alpicola, also co-occurring flavicollis sylvaticus. Methods In particular case of habitat suitability models, classical approaches (GLMs, GAMs, discriminant analysis, etc.) generally require presence absence data. The records provided by museums can clearly give useful information about ecology have already used knowledge-based mapping. paper, we apply ENFA which requires only data, to build a three basis skull collections. Results Interspecific niche comparisons showed that is very specialized concerning selection, meaning its differs unequivocally from average conditions Switzerland, while both sylvaticus could be considered as generalists study area.
