“…Hedychium coronarium forms dense monospecific stands, leading to high biomass production and litter accumulation (Chiba De Castro et al 2019), as well as allelopathic effects on Neotropical riparian tree species (Costa et al 2019). Although the role of rhizome fragments in the spread of H. coronarium remains unknown, dispersal in watercourses after trampling or grazing by native animals has been reported (Chiba de Castro et al 2013), as well as following floods and soil erosion.…”

“…The macrophyte Hedychium coronarium J. Koenig (Zingiberaceae) has been 6 introduced from Asia to the Neotropics, where it is invasive in a wide range of riparian ecosystems. The success of this species has been linked to high aboveground biomass production associated with an extensive rhizome system (Chiba de Castro et al 2016;Chiba De Castro et al 2019). Even though H. coronarium occurs under multiple abiotic conditions and may be dispersed though rhizome fragmentation, it is still unknown how previous exposure to stressful abiotic conditions affects rhizome survival and the performance of the subsequent clonal offspring of the species under ambient growing conditions.…”

“…ii) How are ramet abundance, size and biomass production affected by distinct temperature and light conditions? Considering that H. coronarium occurs under contrasting light regimes in both tropical and temperate ecosystems (Chiba De Castro et al 2019) and may disperse through rhizome fragmentation, we expected that survival and biomass production of rhizomes would not differ significantly in relation to photoperiod or temperature. However, we predicted that survival and biomass production of H. coronarium would decrease as a result of longer desiccation periods, since drought stress can often have a large negative effect on the performance of clonal herbaceous species (Mann et al 2013).…”

Although invasive species are often better competitors than native species, broad environmental tolerance may also drive invasion success. Tolerance to abiotic heterogeneity in riparian ecosystems tends to favour the establishment of alien clonal species, as well as their dispersion by vegetative fragments. Hedychium coronarium J.Koenig is a rhizomatous emergent macrophyte native to Asia, and has invaded Neotropical riparian ecosystems. We assessed the effect of H. coronarium rhizome exposure to distinct abiotic conditions on ramet growth. We exposed rhizomes to different desiccation periods (1 to 90 days), temperatures (15ºC, 25ºC and 35ºC) and light regimes (0h, 12h, 16h), and then assessed the effect of each of these variables on subsequent clonal growth (aboveground biomass production per plant and per ramet, and number and height of ramets) under ambient conditions. While no rhizome survived desiccation periods longer than 30 days, ramet growth among surviving rhizomes was not affected by the period of desiccation. Biomass production per rhizome, ramet biomass and ramet height were significantly lower at 35°C than at 25°C. Constant darkness increased rhizome survival but decreased ramet growth. Although rhizome exposure to extremes of each abiotic variable may hinder the invasion success of H. coronarium, the subsequent aboveground biomass production of surviving rhizomes did not decrease strongly in response to any treatment. This resilience may contribute to successful establishment of H. coronarium after dispersal through rhizome fragments and to varying abiotic conditions.

“…Likar et al [ 15 ] showed pronounced differences in fungal diversity on P. australis litter, with the lowest diversity developed on the litter decomposing at the location with a changing water level. Changes in fungal communities directly affect the decomposition process, as it depends on species richness and the development of the microbial community on the litter [ 16 ].…”

Common reed (Phragmites australis) has high biomass production and is primarily subjected to decomposition processes affected by multiple factors. To predict litter decomposition dynamics in intermittent lakes, it is critical to understand how communities of fungi, as the primary decomposers, form under different habitat conditions. This study reports the shotgun metagenomic sequencing of the initial fungal communities on common reed leaves decomposing under different environmental conditions. We demonstrate that a complex network of fungi forms already on the plant persists into the decomposition phase. Phragmites australis leaves contained at least five fungal phyla, with abundant Ascomycota (95.7%) and Basidiomycota (4.1%), identified as saprotrophs (48.6%), pathotrophs (22.5%), and symbiotrophs (12.6%). Most of the correlations between fungi in fresh and decomposing leaves were identified as co-occurrences (positive correlations). The geographic source of litter and leaf age did not affect the structure and diversity of fungal communities. Keystone taxa were mostly moisture-sensitive. Our results suggest that habitat has a strong effect on the formation of the fungal communities through keystone taxa. Nevertheless, it can also alter the proportions of individual fungal groups in the community through indirect effects on competition between the fungal taxa and their exploitation of favourable conditions.

“…There are studies showing that non-native invasive macrophytes change food webs (Saulino et al 2018), community composition (Mormul et al 2010), beta diversity of invertebrate communities (Gentilin-Avanci et al 2021) and detritus decomposition (de Castro et al 2020).…”

In this review, we evaluate the contribution of Brazilian limnologists to research outputs on aquatic macrophyte ecology. We found a strong “adviser effect” of Professor F.A. Esteves on the Brazilian scientific production focused on aquatic macrophytes. In general, articles focused on a variety of themes, including, inter alia, the role of aquatic macrophytes on the biodiversity of other groups, the interaction between macrophytes and the environment, the effects of environmental factors on aquatic macrophytes distribution and biodiversity, the effects of invasive species on aquatic biodiversity, aquatic macrophytes control and decomposition. Emerging topics (e.g., metacommunity ecology, biodiversity-ecosystem functioning, and patterns of diversity and their determinants) are being embraced by Brazilian limnologists that use aquatic macrophytes as organism models. Despite the fact there is much to study, we think that directly (e.g., via mentoring) or indirectly (via publications), our current knowledge about macrophytes ecology was inspired by Chico Esteves.
