An inter-regional assessment of concentrations and δ13C values of methane and dissolved inorganic carbon in small European lakes
Methane (CH4) and carbon dioxide emissions from lakes are relevant for assessing the greenhouse gas output of wetlands. However, only few standardized datasets describe concentrations of these gases in lakes acro...

North American transect of stable hydrogen and oxygen isotopes in water beetles from a museum collection
Museum collections contain a wealth of insect remains originating from a wide geographic range, which can be used to investigate their utility as a proxy for environmental isotope ratios. Chitinous remains of ...

Hydrogen Isotopes in Beetle Chitin
Beetles, one of the most diverse and long-lived animal groups, provide a trove of ecological and palaeoenvironmental information largely because their exoskeletons contain chitin, a highly resistant biopolymer...

Open AccessEfficiency of different mesh sizes for isolating fossil chironomids for stable isotope and radiocarbon analyses
We examined the effects of sieving with different mesh sizes on the efficiency of processing fossil chironomids from lake sediments for isotope analyses. Results obtained for three different sediments indicate...

Open Access500 years of trophic-state history of a hypertrophic Dutch dike-breach lake
We present a palaeolimnological study encompassing five centuries of trophic-state change of the dike-breach lake De Waay located on the Rhine-Meuse delta (the Netherlands). Diatom-inferred total phosphorus (T...

Open AccessFossil chironomid δ13C as a proxy for past methanogenic contribution to benthic food webs in lakes?
We used a series of experiments to determine whether stable carbon isotope analysis of modern and fossil larval head capsules of chironomids allowed identification of their dietary carbon source. Our main focu...
