Specialist or refugee: Microhabitat use and competition between two sympatric woodland salamanders

Co-occurrence between species may be mediated by ecological differences or competitive interactions, but the nature of these interactions can vary across spatial scales. At coarse scales, species may appear to broadly co-occur, but at fine scales, particularly for species with small home ranges, species may utilize different aspects of the microhabitat such that co-occurrence is limited and competitive interactions are reduced or eliminated.  Leer más.
