Toxicity of rhizomes of the invasive Hedychium coronarium (Zingiberaceae) on aquatic species

Experimental Study on Potential Influence of the Invasive Hedychium coronarium J. König on the Evapotranspiration of Riparian Plant Community

“…Although studies have shown the impact of H. coronarium on native species [31,32] and on riparian ecosystems in Brazil [16,33,34], this species may have a greater impact on their environment than what can be measured through changes on diversity and ecological interactions. The findings of this work show the lower evapotranspiration of an invasive species compared to native ones, which may affect the hydrological cycle.…”

Comparing the sensitivity of aquatic organisms relative to Daphnia sp. toward essential oils and crude extracts: A meta-analysis

“…Regarding the toxicity of CE (N = 20), the effect sizes varied in opposite directions, contributing to an overall non-significant effect. Several contrast aquatic taxa showed significant lower sensitivity to CE than Daphnia sp., namely the bacteria Aliivibrio fischer, the echinoderm Paracentrotus lividus, the fish Oreochromis niloticus, and the plant Lemna minor (Costa et al, 2021;Li et al, 2015;Pastorino et al, 2022). Among the major compounds identified in these studies as potentially inducers of toxicity are: Coronarin D and Coronarin D Ethyl Ether, both diterpenes, known for their cytotoxic activity (Costa et al, 2021); rotenone, an alkaloid, used as pesticide and fish toxin, known to be highly toxic to fish and Daphnia sp.…”

(Li et al, 2015;Zubairi et al, 2016); and eugenol, a phenol, used as fish anesthetic, also reported to be highly toxic to D. magna (Gueretz et al, 2017;Pastorino et al, 2022).…”

“…lnR values are significant when the 95 % CI does not include 0 (black symbols). enzyme among other actions (rotenone) (Costa et al, 2021;Pavela and Benelli, 2016;Zubairi et al, 2016). Species sensitivities are commonly linked to the mode of action of chemicals, but species biological traits can also influence the sensitivity response (Rico and Van den Brink, 2015;Rubach et al, 2012).…”

Relatório temático sobre espécies exóticas invasoras, biodiversidade e serviços ecossistêmicos

“…A grande quantidade de compostos secundários e altas concentrações de fibras em suas folhas afeta principalmente os herbívoros aquáticos (Saulino et al 2018 e a microbiota responsável pela fase inicial da ciclagem de nutrientes, retardando o processo de decomposição (Leite-Rossi et al 2015, Castro et al 2019. Ainda, seus rizomas contêm compostos químicos que inibem a germinação de sementes de árvores nativas ribeirinhas (Costa et al 2019), com alta letalidade para organismos aquáticos, como certas algas, larvas de insetos quironomídeos e microcrustáceos (Costa et al 2021).…”
