“…These factors resulting in the decreased of macroinvertebrate composition but invites the tolerant macroinvertebrate which can survive in hypoxic conditions. In accordance with our results, Toft et al (2003) report the increase of tolerant macroinvertebrate in hypoxic and low dissolved oxygen condition; De Marco et al (2001) report the increase of macroinvertebrate density which is related to the increase of temperature, conductivity, and neutral pH; and De Neiff & Carignan (1997) report that Eichhornia crassipes occurrence has a positive correlation with the dissolved oxygen concentration and conductivity, but negatively correlated with temperature and turbidity.…”

The intensive use of agrochemicals in agricultural areas of Jember’s Regency presents a potential threat to the freshwater ecosystem’s community. The use of the benthic macroinvertebrates community may provide a key to monitor the extent of agrochemical impact to maintain valuable ecosystem services. Macroinvertebrates community structure and environmental factors were studied from September–December 2020 in Jember Regency by comparing three different types of agricultural rivers (organic, semi-organic, and conventional). Five community indices (taxa, individuals, Simpson dominancy index, Margalef species richness, and Shannon diversity index) were used to compare the macroinvertebrates community structure between sites. Using community composition and physicochemical properties (bare sediment, width, depth, water current, pH, conductivity, dissolved oxygen (DO), and temperature), we generated CCA triplot and correlogram plot to investigate the grouping and the correlation between variables and sites. Results on macroinvertebrate composition showed the importance of using sensitive taxa-group and community indices as an indicator of environmental changes. The family of Tipulidae, Naididae, Cysticidae, and Nereididae demonstrated relation to semi-organic agricultural rivers. Temperature and water current correlate to the presence of clean water indicator species such as Philorheitridae and Chironomidae, as observed in organic agricultural rivers. Conventional and semi-organic agricultural rivers were grouped and largely contributed by the 5 families including Ampullariidae, Pachychillidae, Baetidae, Enchytraidae, and Gomphidae. Correlogram plot suggests a complex interaction between macroinvertebrate community and environmental variables. It can be concluded that the intensive use of agrochemicals may lead to a detrimental change toward the diminished quality of freshwater community and environment.

“…The root system of water hyacinth is robust and extensive (Gettys, 2014; Penfound & Earle, 1948), and is capable of reaching up to 1 m in length (Barker, Hutchens Jr., & Luken, 2014). Water hyacinth roots also have effects on aquatic communities by spatially and temporally altering fish assemblages (Troutman, Rutherford, & Kelso, 2007), invertebrate assemblages (Masifwa, Twongo, & Denny, 2001;Poi de Neiff & Carignan, 1997), and habitat structures in aquatic systems (Toft, Simenstad, Cordell, & Grimaldo, 2003). We suggest that the root system of water hyacinth may also effect aquatic systems by acting as a biological barrier of hydrochoric seeds, subsequently causing deposition beneath the mat, germination, and perpetuation of the mat across years if environmental conditions become suitable for persistence (Cronk & Fenessy, 2001;Harper, Adams, & Mavuti, 1995).…”

Water hyacinth (Eichhornia crassipes) is an invasive aquatic macrophyte that is prolific throughout many regions worldwide, but it has recently been detected in several areas of the Midwest United States, outside of its historical range. We assessed the occurrence of water hyacinth in the upper Illinois River to understand the current distribution and potential establishment pathways within a large river system in a temperate climate. We estimated plant biomass and occurrence of seeds in substrate and the water column at locations where water hyacinth occurred and other areas throughout the study area. Biomass of seeds varied temporally and spatially, but no potential water hyacinth seeds germinated during germination trials and germination rates for unscarified water hyacinth seeds from an established population were extremely low. Interestingly, a high abundance and diversity of seeds were detected below water hyacinth mats indicating that water hyacinth root systems may also act as a barrier to hydrochoric seeds in large river systems. Generally, the occurrence of water hyacinth mats and propagules during our study did not pose any apparent issues for commercial navigation due to low overall occurrence and biomass, late occurrence in the growing season, and nongermination of seeds. However, presence of potential water hyacinth in the seed bank and rapid proliferation late in the growing season could pose issues for recreational navigation in low‐flow areas and suggests increased risk if environmental conditions become more suitable for establishment. Occurrence of water hyacinth in the upper Illinois River likely relies on biomass reintroduction annually by humans, and behavioural modification or legal means may be necessary to reduce future occurrences.

“…Studies of invertebrates that colonize these plants showed that T. borellianus is an important member of littoral communities (Poi de Neiff & Neiff 1980). The presence of organisms may be considered as dependent on the habitat -vegetation characteristics (species, plant age), physico-chemical unsuitability, scarcity of food, prey presence-or sampling efficiency, as verified to other crustaceans (Poi de Neiff & Carignan 1997, Berkenbush & Rowden 1998, Lercari & Defeo 1999, Pothoven et al 2004). This study shows that the apparent temporal variation in the spatial distribution of the T. borellianus population differs among the three study sites, being a contagious distribution more frequent than in the case of other sympatric decapods (Williner & Collins 2000).…”

This crab is widely distributed in Brazil (Pará, Mato Grosso, Mato Grosso do Sul), Bolivia, Paraguay and Argentina, mainly in the Paraná and Paraguay rivers (Magalhães 2003).…”

Populations are dynamic in space and time. Abundance of organisms can increase or decrease, having a similar influence on the density-dependent processes and the stochastic events (Morris 1996). Moreover, animal populations have certain synchronization between their fluctuations and the different environmental factors (Ranta 1998, Ruetz et al. 2005 which have a direct influence on density, sex ratio and recruitment. The study of biotic interrelationships such as those occurring in planktonic groups or those of invertebrates living in macrophytes, requires the knowledge of change rate, response time and the possibility for a population or community to repeat these conditions through time (Poi de Neiff & Bruquetas 1989). In rivers with floodplains, such us the Paraná River, different highly dynamic habitats are recognizable, where stability and diversity are primarily conditioned by hydrology and flow of materials. The flooding pulse results in the coupling between the river and floodplain. Moreover, this basin provide shelters, foods and connectivity among different waterbodies (Bonetto & Wais 1995). Therefore, relationships among populations of aquatic organisms like crabs, are subject to the variations of the river.Trichodactylus borellianus is a common freshwater crab species of the Trichodactylidae family from South America (Lopretto 1995, Magalhães & Türkay 1996. Its natural habitat is the aquatic vegetation - The mean crab abundance among the study sites was significantly different, being lower in samples from the environment surrounding the principal channel of the Paraná River. Crab density showed two peaks: the highest occurred during late winter and early spring, and the lowest during late summer. Males were only more abundant in late winter and spring. In spring, summer and autumn, the population showed a contagious distribution. The population displayed a regular arrangement in winter. From mid-spring to mid-autumn juveniles were very frequent whereas adults predominated the rest of the year. Total crab number in the stream nearest to the main channel varied according to the level and temperature of the river. In the other sites, located further from the main channel of the Paraná River, crab numbers and vegetation biomass showed a more similar arrangement with a higher correlation.
