| dc.description.abstract | The effects of climate change are expected to be seen across the globe, as well as impact many different species, including saproxylic beetles. Considering their importance for both biodiversity and as providers of ecosystem services, their potential response to climate change could be crucial for the future health and functioning of their ecosystems. 14 different saproxylic beetle species were examined in two sites in southern Norway, for a period of five different years. Their abundance was analyzed in relation to microhabitat (the hollow of the trunk as opposed to the canopy of the hollow oak), average wind speed, precipitation, mean temperature, humidity and the percentage of days with precipitation. The species were also grouped into different trait-groups based on size, specialization, red list status, geographical distribution, trophic group and whether they are specialized for the hollow, and the group responses were checked against the weather variables. Significant responses were negative for increases in wind speed and percentage of days with precipitation, while the responses for temperature, precipitation and humidity were mixed. The majority of the significant responses were among the generalists and the ''least concern'' red-list group, while specialists and the threatened and endangered species did not appear particularly vulnerable to these weather effects. The results highlight the need to study the effects of weather on the more common species in order to understand the effects of climate change, as their responses could have great impact on communities and ecosystems. | nb_NO |
