“…In summary, bioaccumulation or translocation of heavy metals from benthic sediment to above-ground seagrass compartments are not a function of only morphological or structural and physiological variations in seagrass compartments, but also the element involved [13]. Translocation of metals may be because of interactions between several environmental factors such as the physicochemical properties of an environment and metal speciation [1,10,27]. This might be the key reason for variation in BCF values of heavy metals determined in this study and the highest value of BCF recorded for Cr.…”

“…The use of organisms such as seagrasses as biological indicators of marine pollution gives an advantage as to the provision of information on the spatial and temporal effects of pollutants such as heavy metals [9]. Organisms such as seagrasses with the potential to bioaccumulate heavy metals into their compartments are very important for use in the evaluation of pollutant loading in the environment and understanding the impacts of pollutants in the food web [10,11]. Seagrasses significantly contribute to the primary productivity in the marine ecosystem but are also employed in evaluating the concentration of heavy metals due to the principal uptake routes of heavy metals by these plants [11].…”

The pursuit of a good candidate to biomonitor environmental pollutants has been on the increase. In this study, the concentrations of Fe, Mn, Cu, Zn, Cd, Cr, Pb and Ni in sediment, seawater and seagrass Cymodocea serrulata compartments and antioxidant enzymes activities in C. serrulata were determined. Our results revealed that bioconcentration factors for all the metals were less than 1 (BCF < 1) and concentrations in seagrass compartments were in the order root > leaf > rhizome for Fe and Mn, leaf > root > rhizome for Cu, Zn, Pb and Ni, and root > rhizome > leaf for Cd and Cr. Effect range low concentrations (ER-L) revealed that Cu, Zn, Cd, Pb and Ni concentrations were above ER-L values and Cr concentration was below ER-L values while concentrations in seawater for all the heavy metals were above the estimate average element concentrations in seawater (ECS). Significant variation (p < 0.05) was recorded for heavy metals in sediment, seawater, seagrass compartments and heavy metal concentrations across stations. Influence of heavy metals on antioxidant enzymes activities; catalase (CAT), superoxide dismutase (SOD), glutathione S-transferase (GST) and acetylcholinesterase (AChE) were recorded, and high activities of the antioxidants were recorded in station S8 corresponding to high concentrations of heavy metals in the same station. There is a need for the promotion of biomonitoring networks across the marine environment using C. serrulata and antioxidant enzymes as biomarkers of oxidative stress caused by environmental pollutants.

“…It is propagated either by seeds or vegetatively, by rhizomes, with vigorous growth by the decomposition and assimilation of organic matter as a source of nutrients, reaching about seven tons of rhizomes per hectare (Rangel-Peraza et al, 2017). Thus, T. domingensis is used as a biological filter for urban sewage, industrial effluents rich in heavy metals and erosion control in drainage channels and reservoir banks (Bonanno and Cirelli, 2017). However, anthropic interference in aquatic ecosystems favors the colonization of T. domingensis, which may hinder the production of hydroelectric power, river traffic and agricultural irrigation (Lagerwall et al, 2017).…”

Potential of Colletotrichum typhae H.C Greene mycoherbicide for bio-control of Southern cattail (Typha domingensis Pers.) plants

The anthropic interference in aquatic ecosystems favors the disordered colonization of T. domingensis, damaging the production of hydroelectric power and river traffic. Because of this, studies report the efficacy of fungal mycoherbicides, with control rates reaching as high as 90%. Thus, the objective of this study was to evaluate the potential of C. typhae as a mycoherbicide in bio control of T. domingensis, at in vitro and greenhouse conditions. 107 samples of symptomatic T. domingensis leaves were collected in flooded areas of rivers in Brazil, with identification and isolation of the collected fungal species. The concentration of inoculum was determined to evaluate the incidence and severity of the disease, the influence of temperature on mycelial growth and conidia germination, the effect of temperature and leaf wetness period on T. domingensis infection by C. typhae and the host range test in vitro. The growth of the colonies of C. typhae was higher at 25 to 30 ºC. There was no interference of the photoperiod on germination of the spores, but the highest percentage of germination was occurred at 20 ºC. The influence of environmental conditions on infection of inoculated leaves of T. dominguensis revealed that at 15 ºC and the period of leaf wetness of 48 hours the highest incidence of the disease was observed, as well as the severity for the same period of leaf wetness. The specificity test showed that C. typhae is specifically pathogenic to T. domingensis. This the first report of the occurrence of this pathogen in aquatic macrophytes of this species and in T. domingensis, a potential mycoherbicide for the control of this aquatic weed.

24 The anthropic interference in aquatic ecosystems, favors the disordered colonization of T. domingensis, 25 damaging the production of hydroelectric power and river traffic. Thus, the objective of this study was 26 to evaluate the potential of C. typhae as a mycoherbicide in the control of T. domingensis, in vitro and 27 in greenhouse. 107 samples of symptomatic T. domingensis leaves were collected in flooded areas of 28 rivers in Brazil, with identification and isolation of the collected fungal species. The concentration of 29 inoculum was determined to evaluate the incidence and severity of the disease, the influence of 30 temperature on mycelial growth and conidia germination, the effect of temperature and leaf wetness 31 period on T. domingensis infection by C. typhae and the host range test. The growth of the colonies of 32 C. typhae was higher at 25 to 30 ºC, there was no interference of the photoperiod on germination of the 33 spores, but the highest percentage of germination occurred at 17.39 ºC. The influence of environmental 2 34 conditions on infection of inoculated leaves of T. dominguensis indicated that at 15 ºC and the period of 35 leaf wetness of 48 hours promoted the highest incidence of the disease, as well as the severity for the 36 same period of leaf wetness. The specificity test showed that C. typhae is specific and pathogenic to T. 37 domingensis. Being this the first report of the occurrence of this pathogen in aquatic macrophytes of 38 this species and in T. domingensis in Brazil. 39 Keywords: Biological control; Aquatic macrophytes, Leaf wetness 40 41 Introduction 42 Typha domingensis Pers. is an invasive macrophyte found in the Americas, Europe, Africa, Asia and 43 Oceania, being considered as a native species of South America, occurring throughout Brazil [1]. It is 44 propagated either by seeds or vegetatively, by rhizomes, with vigorous growth by the decomposition 45 and assimilation of organic matter as a source of nutrients, reaching about seven tons of rhizomes per 46 hectare [2]. Thus, T. domingensis is used as a biological filter for urban sewage, industrial effluents rich 47 in heavy metals and erosion control in drainage channels and reservoir banks [3]. 48However, anthropic interference in aquatic ecosystems favors the colonization of T. domingensis, 49 which may hinder the production of hydroelectric power, river traffic and agricultural irrigation [4]. In 50 the United States, this macrophyte accounts for the degradation of almost 12.000 ha -1 of Florida 51 marshes, due its aggressive growth in response to eutrophication by nitrates and phosphates from 52 agricultural and urban waste and frequent fires [5]. In Brazil, it is estimated that the intense growth of 53 T. domingensis in reservoirs of the country's hydroelectric dams extends to about 300 ha -1 in the water 54 mirror. These changes contribute to the reduction of water quality and biodiversity patterns in 55 environments colonized by this species [6]. 56Up to a certain limit, the development of aquatic vegetation c...
