“…The differences in species composition and abundance in the benthos and benthic fauna may be attributed to several environmental factors including differences in the different habitat locations and period of investigation, water quality, and substrate for occupation and food availability. Although, the dominance of Polychaeta as shown in this study is similar and agrees with most research from the Niger Delta creeks [37]. [44]; [39] who attribute this to the high level of pollution tolerance while the low number of species and individual members enumerated in this study is indicative of gradual sediment pollution.…”

“…They recorded six classes of benthic macro-fauna in this study area. The 8 species observed in this study are analogous to the 9 species recorded by [38] in the Ikpoba River but lower than the 28 species reported by [37]. [39] reported 30 species, while [35] also recorded 30 species.…”

“…This phylum is indicative of good ecological similarities. It is equally related to the three phyla (Arthropoda, Annelida, and Mollusca) reported by [37] in the Sombreiro River, the only missing phyla being Chordata. They recorded six classes of benthic macro-fauna in this study area.…”

The study was aimed at examining the impact of untreated discharges from artisanal refineries (illegal bunkering), loading and other related activities on the composition, abundance, distribution, and diversity of zooplankton and macrobenthic fauna from four creek channels of the Isaka-Bundu waterfront in Rivers State, a polluted tidal mangrove wetland. Zooplankton and benthic fauna samples were collected monthly from each of the sampling stations for six months (July to December 2021 using standard sampling methods. Margalef (D), Shannon Wienner (H), and Evenness indices were tools used to determine the species richness and diversity respectively using the SPSS statistical package. This study shows that illegal refining activities and other discharges from industrial and human wastes had an unfavourable impact on the zooplankton and macro-benthic fauna community in Isaka-Bundu waterfronts. The effects are reflected in the spatial variations in the composition with more agitation, especially in station 2 in zooplankton and station 3 in macrobenthic fauna, which has a lower number of species and abundance. The majority of indicator species is a validation of this study, the community structure is an insight into the adverse effects of individual and cumulative activities. More impact was observed on the benthos and benthic fauna and this could be due to their exceptional features and location in the aquatic environment. While therefore, this is an indication that creeks are polluted and regular monitoring should be carried out to report the special degradation level of this creek.

“…Thus Baird et al ( 1981 ), in respect of an estuarine marina in the Eastern Cape, South Africa, and Chou et al ( 2015 ), for three marinas in different stretches of Singapore’s coast, both found minimal consistent difference in faunal abundance and biodiversity inside and outside the marinas concerned, although the Singapore marina subject to least water flow experienced marked siltation and supported a reduced fauna dominated by a few opportunistic cirratulid and spionid polychaetes (see Maxted et al 1997 ). Nevertheless, high levels of domestic and other pollutants can accumulate within the sediments of marina complexes (Guerra-García et al 2021 ), as in other harbours (Guerra-García and García-Gómez 2005 ), and these may have consequences on faunal abundance and composition. Macrofaunas of areas covered by seagrass, however, are greatly affected; coastal development, including marina estates, being regarded as a major destroyer of seagrass beds and their inhabitants (Duarte et al 2004 ).…”

Where ecologically ‘tis better to go brown than green: enhanced seagrass macrobenthic biodiversity within the canals of a brownfield coastal marina

2022

At the start of the 21st century, a coastal residential-estate marina was developed on a previously degraded and polluted brownfield island site within Knysna estuarine bay, Garden Route National Park, South Africa, including the creation of 25 ha of new flow-through tidal canals. Canals near the larger entrance to this system now support permanently submerged beds of seagrass, which in turn support abundant macrobenthic invertebrates. In comparison with equivalent seagrass-associated assemblages present in natural channels around the island, those in the artificial marina canals were similarly structured and dominated by the same species, but the marina assemblages were significantly more species-rich (1.4 x on average) and were more abundant. Indeed, this area of marina supports the richest seagrass-associated macrofaunal biodiversity yet recorded from South Africa. The canals created de novo therefore now form a valuable addition to the bay’s marine habitat, in marked contrast to the generality that marinas developed on greenfield sites represent a net reduction in intertidal and shallow marine area and associated seagrass-associated benthos. If located and constructed appropriately, brownfield marina development and conservation of coastal marine biodiversity clearly need not be antithetical, and brownfield sites may provide opportunity for the location and management of ‘artificial marine micro-reserves’ or for the action of ‘other effective area-based conservation measures’ for soft-sediment faunas.

“…However, in recent years, frequent outbreaks of haze weather, acid rain, oil pipeline explosions, and other pollution incidents have aroused strong concern, and the current environment still cannot reach the comfortable state people need for life [6,7]. Although China has gradually strengthened the supervision of environmental ecology in recent years, and the ecological environment has tended to be stable as a whole, considering that China's current ecological environment is still not optimistic, it will continue to face rapid economic development and population in the future [8]. How to effectively participate in the supervision of the ecological environment through various subjects?…”

In view of the problems of poor air quality and serious soil pollution in the current ecological environment, an online monitoring of ecological environment pollution data in the Internet environment is proposed. The concentration of pollution sources that may appear in the atmospheric environment is analyzed through the analysis coefficient of ecological environment pollutants, and the specific grade data corresponding to the air quality index is determined. Observation and mapping are carried out for the area to be monitored, and then, the monitoring points are determined, the monitoring equipment is arranged, and the soil profile of the area is sampled in the monitoring area. The self-organizing neural network model is used to conduct spatial cluster analysis on the pollution of ecological environment pollution areas, evaluate the sensitivity of soil pollution, and build a land ecological pollution monitoring information model. Based on the Internet of Things technology and the comprehensive use of GPS, sensors, and other technologies and equipment, the framework of monitoring technology is constructed, and the online monitoring of ecological environment pollution data is completed. The experimental results show that the proposed method has high data accuracy in different locations and different seasons, which is consistent with the actual situation; because of the maturity of the Internet of Things technology, compared with the literature method, the method in this paper can provide a cost-effective data foundation, which is more cost-effective, and save time and energy.
