Reconstructing midge consumer–resource dynamics using carbon stable isotope signatures of archived specimens

AR McCormick, JS Phillips, JC Botsch, Á Einarsson… - Ecology, 2023 - Wiley Online Library
Population cycles can be caused by consumer–resource interactions. Confirming the role of
consumer–resource interactions, however, can be challenging due to an absence of data for …

Drivers and resilience of methane-derived carbon contribution to chironomid biomass in boreal lakes

S Belle, E Otsing, H Tammert, V Kisand - Aquatic Sciences, 2024 - Springer
General mechanisms underlying the pathways of methane (CH4)-derived carbon in aquatic
