Ortego, J., and L. L. Knowles. 2021. Geographical isolation versus dispersal: Relictual alpine grasshoppers support a model of interglacial diversification with limited hybridization. Molecular Ecology 31: 296–312. https://doi.org/10.1111/mec.16225
Alpine biotas are paradigmatic of the countervailing roles of geographic isolation and dispersal during diversification. In temperate regions, repeated distributional shifts driven by Pleistocene climatic oscillations produced both recurrent pulses of population fragmentation and opportunities for g…
Speed, J. D. M., G. Austrheim, M. Bendiksby, A. L. Kolstad, and K. E. M. Vuorinen. 2020. Increasing Cervidae populations have variable impacts on habitat suitability for threatened forest plant and lichen species. Forest Ecology and Management 473: 118286. https://doi.org/10.1016/j.foreco.2020.118286
Large herbivores play a key role in temperate and boreal forest ecosystems. Cervidae (deer) population densities and community structure have undergone drastic changes in many parts of the world over the past decades, often with deer populations increasing. Many studies show impacts of Cervidae on m…
Joffard, N., F. Massol, M. Grenié, C. Montgelard, and B. Schatz. 2018. Effect of pollination strategy, phylogeny and distribution on pollination niches of Euro‐Mediterranean orchids I. Bartomeus [ed.],. Journal of Ecology 107: 478–490. https://doi.org/10.1111/1365-2745.13013
1.Pollination niches are important components of ecological niches and have played a major role in the diversification of Angiosperms. In this study, we focused on Euro‐Mediterranean orchids, which use diverse pollination strategies and interact with various functional groups of insects. In these or…
