How much and at what scale? Multiscale analyses as decision support for conservation of saproxylic oak beetles

Bergman, Karl-Olof; Jansson, Nicklas; Claesson, Kenneth; Palmer, Michael W.; Milberg, Per


The main general conclusions were: (i) a multi-scale approach is especially valuable to identify the characteristic scale of response; and that assuming a joint, single scale for all species may result in very poor decision support. (ii) The variation in species' responses to substrate density at different scales means that habitat loss and fragmentation as well as management and restoration may have very different effects upon different species. (iii) Some species respond both to local and landscape scales, indicating that species occurrences in fragmented oak landscapes are affected both by short-term dynamics of the beetles and long term dynamics of the oak substrate. (iv) Maps, useful as decision support, can be constructed based on resource availability (in our case oak density) and characteristic scales. (C) 2011 Elsevier B.V. All rights reserved.
