“…Moreover, our study further showed that the different numbers of the whooper swans distributing in the estuaries 1, 2, and 3 were attributed to the tributaries' salinity and area. These results further verified the conclusions of Elmore et al () and Guillaume et al (). Interestingly, the extent of mixing of fresh water and sea water determined the distributions and numbers of the whooper swans in these estuaries, and the mixing zone with salinity 7.5 was more suitable for the whooper swans to live than other zones.…”

“…Similarly, we also found that the whooper swans liked to cluster and sleep in the estuaries for their safety during the night, as indicated that the estuaries were their main sleeping habitats. Elmore, Miller, and Vilella () found that sleep habitat could provide stable night temperatures and security conditions for birds whose habitat selection was affected by habitat patch and the features of the surrounding landscape (Guillaume et al, ). According to field investigation, these estuaries could provide fresh water, food, and shelter from the wind for the whooper swans.…”

“…During the processes of birds' selecting habitat, habitat patch area and resource availability were important in many factors (Guillaume, Matthieu, Pierre, & Patrick, ; Milinski & Tognola, ). Especially, Pap, Nagy, Balogh, Toth, and Liker () found that the distributions of waterbirds in Lake Balaton were not affected by shoreline urbanization but by the density of plants or animal as food and connectivity between the wetlands.…”

With urbanization influences and economic development, the area and integrity of coastal wetlands are suffering destruction in China, which would affect waterfowl wintering. The Rongcheng Lake is an important wintering ground for migratory birds in Central Asia, especially for whooper swans Cygnus cygnus. In this study, we investigated the numbers and behaviours of the whooper swans in the different habitats of the Swan Lake from November in 2015 to April in 2016, collected 72 water samples in the estuaries, and carried out food addition experiments in order to analyse the behavioural responses and adaptability of the whooper swans to the changing environment. Our results showed that the dominant behaviour of the whooper swans was resting, followed by feeding and locomotion and the whooper swans mainly distributed in the beach, estuary, and lagoon. Moreover, their distributions were affected by fresh water and food availability, whereas the human disturbance played an important role in their distributions and behavioural variations. To adapt to the changing environment, different wintering strategies were adopted by the whooper swans during the different overwintering period. The estuary protection and human feeding were very vital tools to help the whooper swans adjust their body to prepare for migrating next year.

“…Unique to created wetlands is the legacy of prior land use on present nutrient availability; this link is not clearly defined, but may have cascading impacts on the ability of plant communities to recover from grazing events (Foster et al 2003). These impacts can be especially pronounced during migration periods or at over-wintering grounds when grazer populations are at their highest and may result in limiting the re-establishment of plants in subsequent growing seasons (Chaichana et al 2011;Guillaume et al 2014;Bakker et al 2018).…”

“…During this study, great cormorants were observed foraging in the dock and using the AFI for resting, preening and drying of their wings. Mute swans are one of the largest omnivorous wildfowl species (Guillaume et al, 2014) that have gained attention due to their potential negative impact on the abundance of vegetation in wetland habitats (Gayet et al, 2011;Wood et al, 2012Wood et al, , 2013Guillaume et al, 2014). On the upper elevation of the AFI, mute swans can damage and destroy vegetation via feeding, trampling, faecal deposition, transporting seeds to the site and causing pH fluctuations in the substratum (Wood et al, 2012(Wood et al, , 2013.…”

An Assessment of Artificial Floating Islands as a Method of Habitat Creation in Marine Environments

Most megacities are located adjacent to the coast due to the continuous seaward migration of human populations; a process referred to as marine urban sprawl. The subsequent hardening of the natural coastline has caused the loss and degradation of coastal habitats. In order to halt, mitigate and compensate for further losses of biodiversity, it is important that habitat restoration techniques with involve ecological engineering are considered. Artificial floating islands (AFIs) are a habitat creation method used to improve water quality and support biodiversity in aquatic environments. This study aimed to assess the installation of AFIs as a restoration tool in heavily modified coastal water bodies. That included investigating: the suitability of halophytes for transplantation into the AFI matrix; the biofouling communities that establish on the AFIs; the abundance, species richness and behaviour of fish in association with AFIs; the density and behaviour of birds in association with the AFIs; and the public perception of current environmental concerns and therefore, opinion on AFIs as an ecological engineering method. Based on the results of this study sea purslane (Halimione portulacoides) would be recommended for transplantation on AFIs installed in saline environments. The invertebrate community assemblages were notably controlled by the primary settlement of blue mussel (Mytilus edulis) and Australian tubeworm (Ficopomatus enigmaticus). Juvenile phase European sea bass (Dicentrarchus labrax) and gull (Laridae) spp. foraged on the benthic invertebrates that fouled the AFIs underside and European eel (Anguilla Anguilla) rested in the matrix. The public supported the use of AFIs in coastal environments but concerns regarding maintenance and degradation were raised. In conclusion, this study highlighted the importance of AFI size, structure, location and vegetation cover as these factors influence the species composition, degree of isolation and environmental exposure, contributing to the overall success of AFI deployments in heavily modified coastal water bodies.
