  1. ncbi request reprint Temporal dynamics in a pollination network
    Jens M Olesen
    Department of Biological Sciences, University of Aarhus, Aarhus C, Denmark
    Ecology 89:1573-82. 2008
    ..Second, we looked for the ecological properties most likely to be mediating this dynamical process and found that both abundance and phenophase length were important determinants of the number of links per species...
  2. ncbi request reprint The smallest of all worlds: pollination networks
    Jens M Olesen
    Department of Biology Ecology and Genetics, University of Aarhus, Ny Munkegade Block 1540, DK 8000 Aarhus C, Denmark
    J Theor Biol 240:270-6. 2006
    ..Species in pollination networks are much more densely linked than species in traditional food webs, i.e. they have a higher density of links, a shorter distance between species, and species are more clustered...
  3. pmc Missing and forbidden links in mutualistic networks
    Jens M Olesen
    Department of Biological Sciences, Aarhus University, Aarhus C, Denmark
    Proc Biol Sci 278:725-32. 2011
    ..Other kinds of constraint, such as size mismatch and accessibility limitations, are briefly addressed...
  4. pmc The modularity of pollination networks
    Jens M Olesen
    Department of Biological Sciences, University of Aarhus, Ny Munkegade Block 1540, DK 8000 Aarhus C, Denmark
    Proc Natl Acad Sci U S A 104:19891-6. 2007
    ..If these key species go extinct, modules and networks may break apart and initiate cascades of extinction. Thus, species serving as hubs and connectors should receive high conservation priorities...
  5. pmc Strong, long-term temporal dynamics of an ecological network
    Jens M Olesen
    Institute of Bioscience, Aarhus University, Aarhus, Denmark
    PLoS ONE 6:e26455. 2011
    ..However, in spite of this strong internal dynamics of species and links the network appeared overall stable. If this global stability-local instability phenomenon is general, it is a most astonishing feature of ecological networks...
  6. doi request reprint Ecological modules and roles of species in heathland plant-insect flower visitor networks
    Yoko L Dupont
    Department of Biological Sciences, University of Aarhus, Aarhus C, Denmark
    J Anim Ecol 78:346-53. 2009
    ..Within a network, these strongly interacting subgroups of species may exert reciprocal selection pressures on each other. Thus, modules may be candidates for the long-sought key units of co-evolution...
  7. pmc Temporal development and collapse of an Arctic plant-pollinator network
    Clementine Pradal
    Bioinformatics Research Centre, Aarhus University, C, F, Mollers Alle 8, Building 1110, DK 8000 Aarhus C, Denmark
    BMC Ecol 9:24. 2009
    ..Here we study an Arctic plant-pollinator network in two consecutive years using a simple mathematical model and describe the temporal dynamics (daily assembly and disassembly of links) by random mechanisms...
  8. doi request reprint Plant-hummingbird interactions in the West Indies: floral specialisation gradients associated with environment and hummingbird size
    Bo Dalsgaard
    Department of Biological Sciences, University of Aarhus, Ny Munkegade, Building 1540, 8000 Aarhus, Denmark
    Oecologia 159:757-66. 2009
    ..This illustrates that, even within the hummingbird-pollinated flora, pollination syndrome and the degree of specialisation may vary tremendously depending on pollinator morphology and environment...

    Jordi Bascompte
    Integrative Ecology Group, Estacion Biologica de Donana, Consejo Superior de Investigaciones Cientificas, Apartado 1056, E 41080 Sevilla, Spain
    Science 312:431-3. 2006
    ..By using a simple dynamical model, we showed that asymmetries inherent in coevolutionary networks may enhance long-term coexistence and facilitate biodiversity maintenance...
  10. pmc The nested assembly of plant-animal mutualistic networks
    Jordi Bascompte
    Integrative Ecology Group, Estacion Biologica de Donana, Consejo Superior de Investigaciones Cientificas, Apartado 1056, E 41080 Sevilla, Spain
    Proc Natl Acad Sci U S A 100:9383-7. 2003
    ..Our results indicate a nonrandom pattern of community organization that may be relevant for our understanding of the organization and persistence of biodiversity...
  11. ncbi request reprint Coloured nectar: distribution, ecology, and evolution of an enigmatic floral trait
    Dennis M Hansen
    Institute of Environmental Sciences, University of Zurich, Winterthurerstrasse 190, 8057 Zurich, Switzerland
    Biol Rev Camb Philos Soc 82:83-111. 2007
    ..Neither of these possibilities are mutually exclusive. Recent studies have provided experimental evidence for the first two hypotheses, and we suggest promising avenues for future research into this little-known floral trait...
