“…Therefore, they have been widely used as bioindicators for environmental health and integrity. In aquatic environments, habitat integrity is an important factor structuring the aquatic communities of insects including Odonata (Souza et al, 2015;Martin, Maynou, 2016). However, different aquatic insects including Odonata develop several physiological and morphological adaptations to encounter the deterioration in the habitat quality (for morphological adaptation, see Al-Shami et al, 2014b).…”

“…In addition, the stream ecosystem is highly influenced by the riparian vegetation, which contributes allochthonous organic matter that forms a large part of the food base (Hynes, 1970;Mitsch, Gosselink, 2000;Wantzen et al, 2008). According to Souza et al (2015), diversity and distribution of Odonata larvae are generally influenced by alteration in the habitat structure. This increases their potential to be applied as indicators for environmental pollution in the aquatic ecosystems (Berquier et al, 2016).…”

Abdul N.H., Rawi Che S.Md., Ahmad A.H., Al-Shami S.A.: Effect of environmental disturbances on Odonata assemblages along a tropical polluted river. Ekológia (Bratislava), Vol. 36, No. 4, p. 388-402, 2017. Odonata larvae have been intensively used as bioindicators for freshwater pollution as their community structure closely follow changes in the environment and habitat settings. In this study, 28 taxa of Odonata larvae were collected from three stations (upper, middle and lower) of a polluted river in Malaysia. The upper river basin receives effluents from an oil palm plantation. However, the middle station is presumably contaminated with anthropogenic wastes. The lower station is found to receive polluted discharges from aquaculture outlet. Several environmental parameters of water and sediment were continuously measured during the study. The water parameters showed no significant differences amongst the three stations. The species richness of Odonata was 22, 24 and 20 in the upper, middle and lower stations, respectively. The abundance of Odonata was significantly different among the studied sites. The tolerant damselfly, Pseudagrion sp. (41.22%), and facultative dragonflies, Onychothemis sp. (17.12%), were the most dominant taxa along the river stations. Onychothemis sp. and Paragomphus capricornis were equally important at the upper station [Important Species Index (ISI) 25.3 and 24.2%, respectively]. Pseudagrion sp. only scored an ISI value of 9.7%. Pseudagrion sp., P. capricornis and Onychothemis sp. were dominant in the middle station (ISI: 41.2%, 25.9% and 10.9% respectively), and Pseudagrion sp., Onychothemis sp. and Prodasineura sp. dominated the areas with dense growth of submerged aquatic weeds Hydrilla sp. in the lower station (ISI: 47.9, 24.5 and 13.8%, respectively). On the basis of the variations in larval abundance and ISI values, microhabitats differences partly in response to different types of pollutions entering the water structured the Odonata communities in this river basin.

“…Compo Souza et al, 2015). Although not quantified, we observed a higher environmental heterogeneity (stones, branches, aquatic vegetation and varied substrate) in streams relative to the main river, which may explain our results.With respect to the representativeness of the Odonata fauna, the six most numerically more expressive genera in the Iguatemi River basin occurred in both biotopes.…”

This study present an inventory of the genera of Odonata-Anisoptera in lotic environments of the Iguatemi River basin, upper Paraná River, Mato Grosso do Sul State, Brazil. Samplings were performed from December 2006 to February 2009 in the Iguatemi River and eight streams of the basin. We collected 739 immature Odonata, distributed in 25 genera and three families; of which one genus represent a new record for the Mato Grosso do Sul State. Progomphus, Tramea, Elasmotemis, Macrothemis, Aphyla and Phylocycla were the most representative genera in the Iguatemi River basin. The genus accumulation curve predicts an increase of new genera for the Iguatemi River basin.

“…abundant in the environment, is probably associated with the behavior of these predators and its prey. Souza et al (2015) evaluated the influence of habitat structuring on the distribution of Odonata in several Neotropical streams, including the streams studied here. These authors observed that the occurrence of some species was associated with microhabitats with greater leaf biomass in the substrate, used as a local of refuge and larval development (Merritt & Cummins, 1984).…”

Diet of benthivorous fish and prey availability in streams of the Pirapó River basin-PR

et al. 2019

Aim This study aimed to investigate the diet of seven species of fish that consume predominantly benthic macroinvertebrates, and the availability of these organisms in the environment. We analyzed the occurrence of trophic segregation between species and the correlation between the abundance of macroinvertebrates in the diet and in the environment. Methods Fish and macroinvertebrates were sampled in three streams of the Pirapó River basin (Upper Paraná River - Brazil). Differences in diet composition between species were tested using a multivariate permutation analysis of variance (PERMANOVA). A Spearman Correlation was performed to test the relation between the abundance the macroinvertebrates consumed and those available in the environment. Results All species mainly consumed aquatic insect, and significant interspecific variations in diet composition were found for most of them. For five out of the seven species of fish analyzed no significant correlation was detected between the abundance of macroinvertebrates in the environment and in the diet. Conclusions The results showed that most of the species segregate and their diets are not positively correlated with the abundance of preys in the environment, indicating that the most consumed macroinvertebrates were not the most abundant in the environment. These results suggest that the fish species select the macroinvertebrates, and that the morphological and behavioral characteristics of both predators and prey are important in feeding fish from streams.
