“…Second, high microbial activities at low latitudes are counteracted by low invertebrate activities (Haapala, Muotka, & Markkola, ; Walpola, Leichtfried, Amarasinghe, & Füreder, ). Irons et al () explored litter decomposition processes in streams across a latitudinal gradient and concluded that the contribution of the invertebrates to litter decomposition increases with latitude, whereas the proportion attributable to microbes concomitantly decreases with increasing latitude (Haapala et al, ; Leite‐Rossi et al, ; Mathuriau & Chauvet, ; Tonin, Hepp, Restello, & Gonçalves, ; Walpola et al, ). Consistent with our results, for example, Boyero et al () reported unchanged decomposition rates driven by both microbes and invertebrates in an experiment across 22 sites along a latitudinal gradient (0.37–47.8°).…”

“…Empirical studies have undoubtedly improved our understanding of leaf litter decomposition in streams (e.g., Boyero, Pearson, & Camacho, ; Boyero et al, ; Irons, Oswood, Stout, & Pringle, ; Kominoski et al, ; Schlesinger & Hasey, ). Generally, the decomposition of leaf litter in streams is mainly driven by both extrinsic (e.g., environmental factors and water characteristics of streams; Rosemond et al, ; Woodward et al, ) and intrinsic factors (e.g., litter traits; Gonçalves et al, ; Jinggut & Yule, ; Lecerf & Chauvet, ; Leite‐Rossi et al, ). Of the dozens of extrinsic factors that can influence litter decomposition in streams, such as temperature, dissolved nutrients, pH and dissolved oxygen (O 2 ), temperature has undoubtedly captured more than its fair share of attention (Ferreira & Canhoto, ; Ferreira, Chauvet, & Canhoto, ; Follstad Shah et al, ).…”

Aim Leaf litter decomposition in freshwater ecosystems is a vital process linking ecosystem nutrient cycling, energy transfer and trophic interactions. In comparison to terrestrial ecosystems, in which researchers find that litter traits predominantly regulate litter decomposition worldwide, the dominant factors controlling its decomposition in aquatic ecosystems are still debated, with global patterns not well documented. Here, we aimed to explore general patterns and key drivers (e.g., litter traits, climate and water characteristics) of leaf litter decomposition in streams worldwide. Location Global. Time period 1977–2018. Major taxa studied Leaf litter. Methods We synthesized 1,707 records of litter decomposition in streams from 275 studies. We explored variations in decomposition rates among climate zones and tree functional types and between mesh size groups. Regressions were performed to identify the factors that played dominant roles in litter decomposition globally. Results Litter decomposition rates did not differ among tropical, temperate and cold climate zones. Decomposition rates of litter from evergreen conifer trees were much lower than those of deciduous and evergreen broadleaf trees, attributed to the low quality of litter from evergreen conifers. No significant differences were found between decomposition rates of litter from deciduous and evergreen broadleaf trees. Additionally, litter decomposition rates were much higher in coarse‐ than in fine‐mesh bags, which controled the entrance of decomposers of different body sizes. Multiple regressions showed that litter traits (including lignin, C:N ratio) and elevation were the most important factors in regulating leaf litter decomposition. Main conclusions Litter traits predominantly control leaf litter decomposition in streams worldwide. Although further analyses are necessary to explore whether commonalities of the predominant role of litter traits in decomposition exist in both aquatic and terrestrial ecosystems, our findings could contribute to the use of trait‐based approaches in modelling the decomposition of litter in streams globally and exploring mechanisms of land–water–atmosphere carbon fluxes.

“…However, Chironomidae traits, at a fine identification level, may have different categories of feeding habits: deposit-feeder, shredder, scraper, filter-feeder and predator (SERRA et al, 2017). Other studies based on gut content analysis showed that part of this taxon consists of shredder chironomids (SAITO; FONSECA-GESSNER, 2014;LEITE-ROSSI et al, 2016). According to Cummins (2016), analysis of gut content is a poor predictor of FFG assignment.…”

A urbanização causa muitas alterações nas comunidades aquáticas. Sob ocupação urbana intensa, os rios sofrem as maiores modificações estruturais. O objetivo do trabalho foi avaliar os efeitos da urbanização nas características físicas e químicas do habitat e as respostas da urbanização nos grupos funcionais de alimentação (FFG) dos invertebrados. Parâmetros de qualidade da água (temperatura, condutividade, oxigênio dissolvido, pH, fósforo, clorofila-a, turbidez e matéria orgânica) e parâmetros do escoamento foram medidos em áreas pouco e altamente urbanizadas. Os FFG dos macroinvertebrados foram analisados e aplicados como substitutos de atributos do ecossistema. As diferenças na comunidade dos macroinvertebrados entre as áreas pouco e altamente urbanizadas foram avaliadas pelo escalonamento multidimensional não-métrico (nMDS) e pela análise de variância permutacional multivariada (Permanova). No nMDS foram observadas diferenças entre as áreas pouco e altamente urbanizadas. A Permanova mostrou diferença significativa entre os grupos do nMDS. As áreas pouco urbanizadas apresentaram maior riqueza em cada FFG, por outro lado, as áreas altamente urbanizadas apresentaram maiores valores de abundância de organismos coletores e predadores. Assim, a composição dos FFG respondeu às alterações no habitat que foram representadas pelos parâmetros de qualidade da água e do escoamento.

“…Further, the high biomass production of these plants results in the decrease of dissolved oxygen that leads to the exclusion of sensitive species (Schultz & Dibble, 2012). Additionally, invasive macrophytes can alter resource availability which shifts species assemblage (Leite-Rossi et al, 2016). The ecological interaction between invasive macrophyte species and aquatic insects seems to have important implications on the impact of some ecological process, especially those involving predation (Warfe & Barmuta, 2006), herbivory (Boyero et al, 2012) and decomposition (Leite-Rossi et al, 2016).…”

ABSTRACT. Invasive macrophytes threaten freshwater ecosystem biodiversity. We analyzed the impact of the invasive white ginger lily (Hedychium coronarium J. König, Zingiberaceae) on aquatic insect assemblages living in the littoral zone of a tropical reservoir. We took aquatic insect samples in the littoral zone on four main vegetal profi le banks: white ginger monotypic bank, forest partially invaded, native macrophyte monotypic bank and riparian forest. At each vegetal bank, we measured abiotic variables such as dissolved oxygen, pH, water temperature and depth. We analyzed the aquatic insects through abundance, richness and Simpson diversity. We used the non-Metric Multidimensional Scaling (nMDS) analysis to analyze the spatial distribution of each assemblage, and Analysis of similarities (ANOSIM) to verify diff erences amongst dissimilarity distances. Additionally, we analyzed the main taxa associated with invasive macrophytes through indicator species analyses using IndVal index. We observed that the invasive macrophyte banks presented higher abundance of associated specimens, as well as lower dissimilarity of aquatic insect assemblages. Additionally, invasive macrophytes shifted the water pH and littoral depth of reservoir banks. The IndVal index indicated eight aquatic insects as indicator species. Labrundinia unicolor Silva, 2013, Ablabesmyia depaulai Neubern, 2013 and Diastatops Rambur, 1842 were indicator species on banks. We concluded that invasion of white ginger lily caused loss of shallow littoral habitat and altered the pH of the surrounding water probably by high decomposition rate and high production of plant biomass. We suggest the use of species of aquatic insects as indicator species to monitor white ginger lily impact in freshwater systems.
