“…Engl. leaf-litter (Moretti et al 2020) to 72% survival in treatments containing G. glabra leaf-litter (Martins et al 2022). For Triplectides, the survival rate ranged from 72% in treatments containing Eucalyptus globulus Labill.…”

“…(Celastraceae) from the riparian forest of the Barro Branco stream. This plant species is commonly recorded in the riparian forest along streams in the Reserva Floresta Ducke and has been frequently used in eld and laboratory studies of decomposition in Amazon streams (e.g., Martins et al 2017aMartins et al , 2022Firmino et al 2022). The trait characteristics of G. glabra were: toughness = 129.6 ± 66.8 g; carbon = 44.5%; nitrogen = 1.5%; polyphenols = 2.5%; tannins = 1.3%; lignin = 48.1%; cellulose = 20.3% (Martins et al 2017a).…”

“…However, controlling these variables can be limited by nancial resources and the duration of the surveys (Carpenter et al 1995). For example, using mineral water in experiments (e.g., Martins et al 2017aMartins et al , 2022Firmino et al 2022Firmino et al , 2023 has logistical advantages because it reduces trips to streams to collect water. However, the effects of its use on shredders and foliar consumption in microcosm experiments are still unknown.…”

Experiments are useful scienti c tools for testing hypotheses by manipulating variables of interest while controlling for other factors that can bias or confuse the results and their interpretation. However, to ensure accuracy and reproducibility, experiments must have transparent and repeatable methodologies. We experimentally tested the effect of different methodological approaches in microcosm experiments on the consumption and survival of shredders. We found that the shredder species, the presence or absence of the case in the shredders, and the use or non-use of air-pumps in the microcosms did not affect the shredder performance (i.e., consumption and survival). Furthermore, the type of water (stream or bottled) did not affect shredder performance. On the other hand, the amount of light had a negative effect on shredder performance, with constant light (i.e., 24 hours) reducing shredder consumption and survival. Our results highlight the importance of transparent and repeatable methodologies in experiments. Different methodological approaches in microcosm experiments can in uence the results and their interpretation. This nding is especially worrying when we measure gains and losses in ecosystem functions by recreating natural conditions in the laboratory, where factors that are not of interest may affect or interact with the results. In addition, our ndings offer valuable insights that can help researchers design experiments with shredders from neotropical streams.
