Latitudinal patterns of aquatic insect emergence driven by climate

Aim: Emerging aquatic insects link aquatic and terrestrial ecosystems across the Earth. Their diversity, abundance and functional importance mean their emergence is an important phenological event. Nevertheless, aquatic insect emergence is understudied at a global scale compared to other phenological events, despite changing phenology being one of the most significant ecological responses to climate change. Here, we quantitatively describe the global patterns, and key proposed drivers, of seasonal aquatic insect emergence, to further understand how these patterns might change in the future.
Location: Global.
Time period: 1950–2018.
Major taxa studied: Emerging aquatic insects.
Methods: We extracted monthly emergence data from 86 studies across 163 sites to construct 1053 annual emergence curves. We parameterised the curves using two complementary metrics of seasonality, which were modelled against geographic and climatic variables to determine the direct and indirect relationships betwe..., Further methodological details on data collection can be found within the published paper and its supplementary material., This archive contains the dataset used for all modelling, analysis and plotting carried out in this paper.
