“…The white-ginger lily Hedychium coronarium J. König (Zingiberaceae) is an amphibious macrophyte native from tropical Asia that became an aggressive invader in Brazilian riparian zones and other American zones due to rapid growth, impacting on the maintenance of biodiversity and ecosystem services in open and forested sites (Kissmann and Groth 1999;De Castro et al 2016). It presents e cient vegetative reproduction through rhizomes from which small fragments can be dispersed by water ow and originate new invasion spots (Stone et al 1992;Kissmann and Groth 1999).…”

Invasive species can affect ecosystems functioning by forming dense monospecific stands and outcompeting native plants. However, the performance of the invader depends on its plastic responses to abiotic attributes of invaded communities. Understanding the interplay between intraspecific competition and environmental conditions is important to elucidate the domain and aggressive potential of invasive species. Here, we assessed the performance of the invasive Hedychium coronarium in two levels of intraspecific competition created through rhizome density under full light and partial shade. We tested the influence of light, density and their interaction on ramet length and number of ramets during the first three months after planting (phase 1) and after 22 months (phase 2), and on rhizome dry weight and the ramet/rhizome biomass ratio in phase 2. In both phases, ramets were longer under shade and the number of ramets was higher under low rhizome density indicating lower intraspecific competition. In phase 2, there was a negative effect of rhizome density on ramet length, but it was restricted to shade, probably due to the aggravation of competition for light. Rhizome dry weight was greater under shade conditions and it was not affected by rhizome density, and ramet/rhizome ratio did not differ between treatments. Our results supported a large phenotypic plasticity of H. coronarium ramets, which allowed similar performances despite variations in environmental conditions and population densities. We suggest that this mechanism of energy allocation enhances the success of this invasive plant in varied habitats, such as open and closed, forested sites.

“…Urochloa arrecta was recorded in the Itanhaém River (southern region), P. repens in the Una River (central region), and H. coronarirum in the Ubatumirim and Puruba Rivers (northern region). These exotic species have been reported as aggressive invaders in aquatic ecosystems of other tropical and subtropical regions, negatively affecting the richness, diversity and abundance of native aquatic macrophytes (Fernandes et al 2013, Michelan et al 2013, Amorim et al 2015, Castro et al 2016, Overholt & Franck 2017.…”

Inventory of Aquatic Macrophyte Species in Coastal Rivers of the São Paulo State, Brazil

et al. 2019

The coastal region of the São Paulo state (Southeastern Brazil) is marked by the presence of the Serra do Mar, a system of mountain ranges with altitude up to 1,000 m. Due to the difference of proximity of the mountain range to the coastline, the coastal plains have different width. As a consequence, the rivers that cross the plains also have different length, greater or less influence of marine waters and slope variation. We carried on an inventory of aquatic macrophyte species in order to assess the species and life form richness and latitudinal distribution in this region. Macrophytes were inventoried at 100 sampling sites in eight rivers (between 9 and 19 sites per river) in March 2017. General descriptions on taxonomic aspects, life forms and frequency of occurrence of the macrophytes were explored. We recorded 45 taxa of aquatic macrophytes belonging to 24 families. Three species are exotic, but they presented low frequencies of occurrence. The vast majority of the taxa have emergent life form. Floating and submerged macrophytes were found in only two rivers. The most frequent species were Crinum americanum L. (Asparagales, Amaryllidaceae), Spartina alterniflora Loisel. (Poales, Poaceae) and Schoenoplectus californicus (C. A. Mey.) Soják (Poales, Cyperaceae). Most taxa are rare in terms of occurrence. Only four species occurred along a large part of the north-south stretch sampled and these, possibly, have a wide tolerance to the variation in resource requirements and salinity. The north-south gradient of the taxa occurrence may be related to the diversity of environmental characteristics due to differences in the rivers length and coastal plains width.

“…Ginger lily was brought to South America from Asia as an ornamental plant, and it has a high capacity for propagation and rapid growth [ 69 ]. Ginger lily growth causes shading of native herbs and seedlings, affecting plant community structure, and rapidly decreasing plant diversity [ 70 – 72 ].…”

Plant invasion: Another threat to the São Paulo Marsh Antwren (Formicivora paludicola), a species on the verge of extinction

et al. 2017

During the past 100 years in densely populated south-eastern Brazil, wetlands have been severely transformed due to urbanization, agriculture and mining. The recently discovered São Paulo Marsh Antwren (Formicivora paludicola) is endemic to these wetlands, and is listed as “Critically Endangered” by the IUCN. The species is only found in an area of 1.42 km2, it has a sparse and fragmented distribution, low dispersal capacity, and has probably lost around 300 km2 of habitat in the past 100 years. Furthermore, very little is known about F. paludicola natural history, and so it is difficult to construct a robust conservation plan. Using Kernel home range estimations and the Adjusted-SD/Torus Shift test (a novel tool for animal-habitat association studies), we showed that the species avoids patches of the alien invasive ginger lily (Hedychium coronarium). Given the high density of their population (3.6 mature individuals/ha), F. paludicola could thrive in relatively small areas of suitable wetlands protected from human occupation and water contamination, however special attention should be paid to biological invasions, which may represent a serious threat to the remaining populations. Protecting a few small wetlands used by F. paludicola would be an important step towards general conservation and restoration of Atlantic Forest wetlands and its endemic endangered species.
