Fig 2.
Seasonal changes in biweekly averaged abundance for all species over 2017 and 2018 collection period in Ottawa and the South Nation river sites.
The “other species” are rare species with average abundance less than 10. They include An. barberi, An. walkeri, Cs. melanura, Cs. minnesotae, Cs. morsitatns, Cx. salinarius, Cx. territans, Oc. abserratus, Oc. cantator, Oc. communis, Oc. dorsalis, Oc. excrucians, Oc. fitchii, Oc. intrudens, Oc. japonicus, Oc. provocans, Oc. punctor, Oc. sticticus, Oc. triseriatus, Ps. ciliata and Ps. ferox.

Variation partitioning according to species among weather, land use, spatial fixed effect and the temporal and spatial unit random effects from the occurrence-model.
Community-level adjusted Efron’s pseudo-R2 of weather-only model (0.24) was compared to that of weather-and-land-use model (0.28). Each pair of bars corresponds to one species.

Community-level adjusted Efron’s pseudo-R2 of weather-only model (0.21) was compared to that of weather-and-land-use model (0.22). Each pair of bars corresponds to one species.
