“…Residues larger than 210 pm were searched with a dissecting microscope to recover invertebrates missed. Chironomid larvae were identified to the lowest practical level, termed taxa, using mainly Ashe & Murray (1980), Brundin (1966), Coffman & Ferrington, 1984, Hirvenoja (1973, Johannsen (1937), Oliver et al (1978), Oliver (198 l), Oliver & Roussel (1983), Pankratova (1970), Roback (1978), Simpson & Bode (1980), Soponis (1977) and Tilley (1978).…”

Simultaneous hourly net collections in a meadow and canyon reach of a mountain stream determined die1 and spatial abundances of drifting Chironomidae larvae. Sixty-one taxa were identified to the lowest practical level, 52 in the meadow and 41 in the canyon. Orthocladiinae was the most abundant subfamily with 32 taxa and a 24 h mean density of 294 individuals 100 m-3 (meadow) and 26 taxa and a mean of 648 individuals 100 m-3 (canyon). Chironominae was the second most abundant subfamily. Nonchironomid invertebrates at both sites and total Chironomidae larvae (meadow) were predominantly night-drifting.Parakiefferiella and Psectrocladius were day-drifting (meadow) whereas 8 other chironomid taxa (meadow) and 2 taxa (canyon) were night-drifting. All others were aperiodic or too rare to test periodicity, Stempellinella cf brevis Edwards exhibited catastrophic drift in the canyon only. The different drift patterns between sites is attributed to greater loss of streambed habitat in the canyon compared to the meadow as streamflow decreased. Consequent crowding of chironomid larvae in the canyon caused catastrophic drift or interfered with drift periodicty. This study adds to knowledge of Chironomidae drift and shows influences on drift of hydrologic and geomorphic conditions.

Five new species, Apometriocnemus beringensis, Cricotopus (Cricotopus) bifurcatus, Doithrix dillonae, Hydrobaenus piloculus, and Paratrissocladius lawrencensis, are described. The following new combinations are established: Bryophaenocladius astis (Roback 1951b); Compterosmittia nerius (Curran 1930); Parakiefferiella subaterrima (Malloch 1915); Paratrichocladius nitidus (Malloch 1915); Pseudosmittia nanseni (Kieffer 1926); and Zalutschia sivertseni (Aagard 1979). New genus name synonymies are Maricladius Sublette, 1970 with Parakiefferiella Thienemann, 1936; and Prosmittia Brundin, 1956 with Pseudosmittia Goetghebuer, 1932. New species name synonymies are Spaniotoma (Trichocladius) senex Johannsen, 1937 with Trichocladius nitidellus Malloch, 1915 (= Acricotopus nitidellus); Hydrobaenus traenis Roback, 1957b with Hydrobaenus astis Roback, 1957b (= Bryophaenocladius astis); Compterosmittia clavigera Saether, 1982 with Camptocladius nerius Curran, 1930 (= Compterosmittia nerius); Cricotopus flannagani Saether, 1971 with Cricotopus macraei Saether, 1971; Gymnometriocnemus marionensis Saether, 1969 with Metriocnemus subnudus Edwards, 1929 (= Gymnometriocnemus (Gymnometriocnemus) subnudus); Gymnometriocnemus (Raphidocladius) acigus Saether, 1983 with Metriocnemus brumalis Edwards, 1929 (= Gymnometriocnemus (Raphidocladius) brumalis); Limnophyes spatulosus Saether, 1975 with Limnophyes borealis Goetghebuer, 1933; Limnophyes cristatissimus Saether, 1975 with Camptocladius fumosus Johannsen, 1905 (= Limnophyes fumosus); Limnophyes hudsoni Saether, 1975 with Limnophyes immucronatus Saether, 1969; Hydrobaenus hudsoni Saether, 1977 with Chaetocladius (Parachaetocladius) abnobaeus Wülker, 1959 (= Parachaetocladius abnobaeus); Parakiefferiella torulata Saether, 1969 with Camptocladius subaterrimus Malloch, 1915 (= Parakiefferiella subaterrima); Trichocladius helis Roback, 1957b with Orthocladius nitidus Malloch, 1915 (= Paratrichocladius nitidus); Syncricotopus fontinalis Saether, 1969 with Chironomus rufiventris Meigen, 1830 (= Paratrichocladius rufiventris); Pseudorthocladius (Lordella) comans Saether and Sublette, 1983 with Pseudorthocladius (Lordella) wingoi Saether and Sublette, 1983; Smittia triappendiculata Goetghebuer, 1931 with Camptocladius forcipatus Goetghebuer, 1921 (= Pseudosmittia forcipatus); and Psilometriocnemus cristatus Saether, 1982 with Psilometriocnemus triannulatus Saether, 1969. Major new distribution records are given for 49 species including 8 Nearctic and 32 Canadian. A key to adult males of Nearctic Limnophyes is given.

“…However, cyanobacteria contain nutrients and active macromolecules, such as pigments, carbohydrates, lipids (including essential fatty acids), proteins, vitamins, and minerals, which are necessary for the growth and maturation of macroinvertebrates [ 76 , 77 , 81 , 82 , 83 ]. A gut content analysis (microscopy, serology or DNA) has proven that certain grazer invertebrates feed on cyanobacteria [ 30 , 78 , 83 , 84 , 85 , 86 , 87 , 88 , 89 , 90 , 91 , 92 ], and they even prefer filamentous species [ 84 , 86 , 90 , 93 ], but their ingestion in other grazers may accidentally occur because some cyanobacteria species are usually found as epiphytes of macrophytes, or as part of complex biofilms, periphyton and detritus [ 2 , 3 , 83 , 94 , 95 ]. This dichotomy has led us to wonder whether the simple detection of cyanobacteria in grazers’ gut contents can be nutritionally considered by proposing an enzyme analysis as the most appropriate way to confirm that invertebrates have the capacity to digest cyanobacteria and to absorb their nutrients [ 84 ].…”

Cyanobacteria and Macroinvertebrate Relationships in Freshwater Benthic Communities beyond Cytotoxicity

Cyanobacteria are harmful algae that are monitored worldwide to prevent the effects of the toxins that they can produce. Most research efforts have focused on direct or indirect effects on human populations, with a view to gain easy accurate detection and quantification methods, mainly in planktic communities, but with increasing interest shown in benthos. However, cyanobacteria have played a fundamental role from the very beginning in both the development of our planet’s biodiversity and the construction of new habitats. These organisms have colonized almost every possible planktic or benthic environment on earth, including the most extreme ones, and display a vast number of adaptations. All this explains why they are the most important or the only phototrophs in some habitats. The negative effects of cyanotoxins on macroinvertebrates have been demonstrated, but usually under conditions that are far from natural, and on forms of exposure, toxin concentration, or composition. The cohabitation of cyanobacteria with most invertebrate groups is long-standing and has probably contributed to the development of detoxification means, which would explain the survival of some species inside cyanobacteria colonies. This review focuses on benthic cyanobacteria, their capacity to produce several types of toxins, and their relationships with benthic macroinvertebrates beyond toxicity.
