The diversity effect on decomposition, through the litter-mixing effects plays a central role in determining the nutrient and carbon dynamics in ecosystems. However, the litter-mixing effects are centered on a leaf litter perspective. Important aspects related to intraspecific interaction and biomass concentration are rarely evaluated, even though they could be essential to determine the litter decomposition dynamics. To our knowledge, we introduced a new perspective to evaluate whether and how the interaction between flowerand leaf litter affects the occurrence, direction, and magnitude of litter-mixing effects in terrestrial and aquatic ecosystems. We performed laboratory experiments using flowerand leaf litter from the yellow trumpet tree Tabebuia aurea (Silva Manso) Benth. and Hook. f. ex. S. Moore as a model. To obtain realistic results, we manipulated various scenarios of flower : leaf litter biomass proportion and measured 13 functional traits. Litter-mixing effects were consistent in both aquatic and terrestrial environments, with faster decomposition of both litter types in mixtures compared to their monocultures (synergistic effects) . Litter-mixing effects were stronger in the terrestrial environment and at higher flower : leaf litter biomass proportions. Our results indicate that synergistic outcomes are mainly associated with complementary effects. Flower litter had a higher concentration of labile C compounds, N, P, and K and lower lignin concentrations, representing a labile litter, while leaf litter had a higher concentration of lignin, Ca, Mg, and Na, representing a refractory litter. Our results demonstrate the impor-  \ntance of litter-mixing effects between flower and leaf litter via complementary effects. These results shed light on the secondary consequences of flower litter on decomposition, suggesting that species with high reproductive investment in flower biomass may play an important role in the nutrient and carbon recycling of diverse plant communities, exerting a pivotal role in biogeochemical dynamics.  \n1 Introduction  \nDecomposition is an important ecosystem process because of its role in the energy and matter flows within and across terrestrial and aquatic ecosystems, which affects the cycling of nutrients and carbon (C) in the biosphere (Cebrian and Lartigue, 2004; Tiegs et al., 2019) . Up to 90 % of the primary production accumulates as organic matter (OM) in the soil (Cebrian, 1999), and a considerable proportion of this stock is transported to rivers, lakes, and oceans, contributing to the stocks of OM in aquatic environments, along with autochthonous OM (Tranvik et al., 2009; Aufdenkampe et al., 2011) . Decomposition is controlled by abiotic factors such as temperature and hu","cbCailu0H8RyqeR8","https://ap.wps.com/l/cbCailu0H8RyqeR8","pdf",4390359,1,18,"English","en",105,"# Introduction\n## Decomposition importance and drivers\n## Litter quality and diversity\n# Study design and experimental approach\n## Litter sources and biomass proportion scenarios\n## Functional traits measured\n# Results\n## Consistency across aquatic and terrestrial environments\n## Strength of effects by environment and biomass ratio\n# Mechanisms and implications\n## Complementary chemical properties\n## Links to nutrient and carbon recycling","[{\"question\":\"What research gap does the study address about litter-mixing effects?\",\"answer\":\"Most prior work has focused on leaf-litter perspectives.
