Abstract Understanding the effects of mining activities on Amazonian streams and their impact aquatic communities is paramount importance in current context resource overexploitation society. In this study, we assessed significance environment interspecific interactions organization patterns semiaquatic insect species a mineral extraction region eastern Amazon. We utilized morpho functional characteristics 22 from suborder Gerromorpha (Heteropteran), considering both abundance sexual dimorphism these species. Additionally, quantified density riparian vegetation surrounding each stream to categorize sampling points evaluate whether there are differences distribution among categories. sampled 16 sites, categorized into two treatments based percentage forested deforested areas located Capim River Basin. did not find action environmental filters total assembly; however, found significant morphological divergence for all traits analyzed. On other hand, separation with different portions showed that between them regarding patterns. Forested within 500m radius have distributed over larger area, indicating greater availability or can use resources more efficiently. Our results demonstrate studied communities, as well mitigating impacts caused by activities.

The Peruvian fauna of aquatic and semiaquatic bugs comprises 233 species, representing 70 genera, 15 tribes, 29 subfamilies, 16 families. Many these species (22%) are endemic to the country, while 49% occur in Peru other South American countries, 21% found throughout Neotropics, 8% widely distributed Americas. These proportions similar among three infraorders treated here. There is a slight predominance Gerromorpha (48%) over Nepomorpha (46%) Peru, both much more speciose than Leptopodomorpha (6%). same also occurs Colombia Ecuador, whereas richer Brazil, Argentina, Chile. Within 92% have been recorded from Atlantic slope, 16% Pacific only 2% Titicaca slope.

The use of aquatic insects in ecological studies oil palm plantations provides an effective evaluation biodiversity loss caused by changes habitat. Approaches at the population or community level associated with biomarker analyses might help management and conservation impacted habitats. Our aim was to assess detoxification responses (Glutathione S-transferase activity) three invertebrates (Mnesarete aenea, Cylindrostethus palmaris, Campylocia anceps) forested areas Eastern Brazilian Amazon. A total 20 streams were sampled during dry season 2017, municipality Tailândia, Pará – Brazil. response this exposure related water temperature, pH, dissolved oxygen, canopy cover habitat integrity index. species M. aenea C. palmaris showed differences induction, higher specific activity than forest areas. conversion natural landscape agrochemicals affect dynamics organisms that are sensitive quality. We suggest Habitat Integrity Index between Amazon is a determining factor increased GST induction aenea. This result indicates organism act as sentinel for evaluations, providing early warning signal via its biochemical could prevent levels.

Abstract Length–biomass equations are relatively easy and cost‐effective for deriving insect biomass. However, the exact relationship can vary between taxa geographical regions. Semi‐aquatic bugs abundant indicators of freshwater quality, but there no studies investigating effect habitat disturbance on their biomass, although it is useful in assessing ecological processes. We identified best‐fit length–biomass models to predict biomass semi‐aquatic (Hemiptera, Gerromorpha) collected from streams Sabah, Malaysia. used 259 juvenile adult compare a range plausible functions, assess whether relationships differed across following families body forms: (1) Cylindrostethinae, Gerrinae, Ptilomerinae, which subfamilies within Gerridae consisting small‐to‐large that have long slender bodies, (2) Halobatinae, subfamily Gerridae, small‐to‐medium with wide heads thoraxes as well short abdomens, (3) Veliidae, small stout bodies. Estimation five fitting functions – linear regression, polynomial regression order 2, 3, 4, power groupings: three forms combined; each form life stages (juvenile adult) separated. Power regressions were best fit predicting forms, predictive was higher when different calculated separately (specifically Halobatinae Veliidae). Splitting by did not always result additional improvement. The this study expand scope possible future research bugs, particularly Southeast Asia, allowing more consider biomass‐related questions.
