“…Thus, these traits are overall sensitive to increasing human impacts in forested systems and their disappearance should thus serves as a warning signal. The results pertaining to the distribution of these traits are similar to those reported by Guilpart et al (2012), Pallottini et al (2017), and Milosevic et al (2018) indicating that traits such as shredding and scrapping were associated with riverine stations close to natural condition. Functional feeding groups (FFGs) are commonly used for assessing disturbances in forested systems (Stepenuck et al, 2002;Mondy and Usseglio-Polatera, 2014).…”

“…Globally, the trait-based approach has grown in popularity for assessing and monitoring riverine health (e.g., Statzner and Beche, 2010;Descloux et al, 2014;Kuzmanovic et al, 2017;Serra et al, 2017;White et al, 2017;Berger et al, 2018;Castro et al, 2018;Krynak and Yates, 2018;Milosevic et al, 2018;Desrosiers et al, 2019), but only few studies have attempted to develop and apply the trait-based biomonitoring approach for assessing riverine systems health in the Afrotropical region (e.g., Akamagwuna et al, 2019;Edegbene et al, 2020a,b;Odume, 2020). The studies of traits in the Afrotropical region have focused largely on assessing freshwater systems subject to urban, agricultural, and industrial pollution.…”

Can Macroinvertebrate Traits Be Explored and Applied in Biomonitoring Riverine Systems Draining Forested Catchments?

Trait-based approach (TBA) in recent time has received tremendous attention as complementary tool over taxonomic-based approach in assessing ecological health of riverine systems in developed countries, but in the Afrotropical region the trait-based approach is still in its infancy. No trait-based approach has been developed for riverine systems draining forested catchment in the Afrotropical region. Hence, this study was conducted to explore and apply macroinvertebrates traits as potential biomonitoring tools in assessing ecological health of riverine systems draining forested catchments in the Niger Delta area of Nigeria. Selected physico-chemical variables were sampled together with macroinvertebrates in 18 stations of 10 riverine systems from 2008 to 2012. The 18 stations were classified into three ecological classes namely near natural stations (NNS), slightly disturbed stations (SDS), and moderately disturbed stations (MDS) using physico-chemical-based classification with the aid of principal component analysis (PCA). The results revealed traits such as possessions of hardshell body armouring, preferences for clear and transparent water and opaque water, climbing and crawling mobility mechanisms, large (>20–40 mm) body size, preferences for scrapping, shredding, and grazing feeding habits to be associated with NNS and SDS based on RLQ (R, physico-chemical variables; L, taxa; Q, traits) analysis performed. Thus, these traits were deemed to be sensitive to human impact in forested systems. Also, traits such as tegument/cutaneous respiration, soft and exposed body armouring, burrowing mobility mechanism, spherical body shape, preference for detritus [fine particulate organic materials (FPOM)] food materials, small (>5–10 mm) body size and preference for filter feeding mechanism were associated with MDS. Hence, they were deemed tolerant of human impact in forested systems. A fourth-corner test performed revealed tegumental/cutaneous respiration preference, soft and exposed body armouring and burrowing mobility mode, which were associated with the MDS on the RLQ ordination were also positively correlated to 5 day biochemical oxygen demand (BOD5); while preference for clear and transparent water, which were positively associated with MDS, were also positively correlated with pH and negatively correlated to dissolved oxygen (DO). Overall, this study affirmed that the TBA can be explored in biomonitoring riverine systems draining forested catchments. Nevertheless, we suggest the trait-based approach to be further explored, with a view to developing trait-informed indices for biomonitoring Afrotropical riverine systems.

“…Urban pollution can introduce elevated dissolved solids into forested riverine systems, thereby increasing the risk of absorbing dissolved materials-e.g., metals that are potentially toxic [13,14,37,38]. Organisms with a large body size have been reported to have a large surface area to volume ratio, which increases their likelihood of increased exposure and adsorption to chemicals due to their increased surface area to volume ratio compared to organisms possessing a small body size [45,46]. Organisms with a large body size have also been predicted to be particularly sensitive to pollution because they are often associated with the production of fewer offspring per reproductive cycle [47].…”

The influence of urbanization on macroinvertebrate traits was explored in forested rivers in the Niger Delta area of Nigeria. Physico-chemical variables were sampled on a monthly basis alongside macroinvertebrates in 20 sites of 11 rivers spanning 2008–2012. Physico-chemical variables were used to classify the 20 sites into three ecological classes, namely: least impacted sites (LIS), moderately impacted sites (MIS) and highly impacted sites (HIS) using principal component analysis. Our results based on RLQ (R = physico-chemical variables, L = macroinvertebrate taxa and Q = macroinvertebrate traits) and fourth-corner analyses revealed that large body size, grazing and hardshell were positively significantly associated with LIS on the RLQ. They were also either negatively correlated with any two of water temperature, nutrients, BOD5 and flow velocity or positively significantly correlated with increasing DO. Thus, these traits were considered sensitive to urban pollution in forested rivers. Burrowing, predation and pupa aquatic stage, which were positively associated with HIS, were also significantly negatively correlated with increasing DO, and were deemed tolerant of urban pollution in forested rivers. Box plots and a Kruskal–Wallis test revealed that the three sensitive traits were significantly highest at LIS (p < 0.05) except grazing; while the three tolerant traits were significantly highest at MIS (p < 0.05) except burrowing. Overall, this study revealed that urban pollution influences macroinvertebrate traits differently in forested rivers.

“…As its output, this method ordinates and classifies the samples in a 2-dimentional neural network. ANNs have already been applied in many aspects of ecological studies: for clustering, classification, estimation, prediction, and data mining at different ecological levels [27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44]. Since the data set in the present study is multivariate, large and nonlinear, and as the abundance of many parasitic species broadly varies over different samples (aphids), the SOM method is a suitable approach for testing the main hypothesis and describing the complex interactions within the trophic associations.…”

The parasitoid species Ephedrus plagiator (Nees, 1811) (Hymenoptera: Aphidiinae) is one of the most important biological agents against pest aphids. We investigated whether this species was in competition with some other aphidiine species for the same hosts. We thus examined its potential in biological programs to control aphids. We applied an unsupervised artificial neural network, a self-organizing map (SOM), which classified the competitive parasitoids into seven groups. The SOM also visualized the distributional pattern of 31 parasitoid wasps along the neural network, revealing their competitive ability in relation to E. plagiator. Indicator value (IndVal) analysis quantified the competitive ability and showed that the most competitive species with regard to E. plagiator were Lysiphlebus testaceipes (Cresson, 1880), L. fabarum (Marshall 1896), L. cardui (Marshall 1896) and Binodoxys angelicae (Haliday, 1833). These species appeared in four different SOM groups and mostly parasitized the Aphis fabae Scopoli, 1763 (Hemiptera: Aphididae) host.
