“…5). Hobak and Stanley (2001) and Englische et al (1982) reported that chaoborids can survive anoxia for at least 24 h if the temperature is not higher than 14°C, as in our case. Of course, such strategy is not favourable for organisms, but later in summer, when YOY fish gapelimitation was reduced, perch [30 mm might have preyed on invertebrate predators (Gélinas et al 2007).…”

Comparison of fish and phantom midge influence on cladocerans diel vertical migration in a dual basin lake

Diurnal vertical migrations (DVM) behaviour of cladocerans was investigated in two mesotrophic Irish lakes connected by a canal, characterised by interesting differences in the presence of zooplanktivorous predators. In Doon Upper, fish (mostly juvenile perch and roach) and a little-studied phantom midge Mochlonyx fuliginosus (Chaoboridae) were found, but Doon Lower was solely inhabited by fish. As the presence of diverse predators may alter spatial avoidance behaviour of zooplankton prey in different ways, the aim of this study was to determine whether and how two predator types, fish and phantom midge larvae, have changed DVM pattern of cladocerans during day and night in Doon lakes. Two sampling series of phytoplankton, zooplankton, fish, and water physical analyses were conducted on 09-10 June and 19-20 September 2007 in both lakes. In the study conducted in June, under a similar distribution of M. fuliginosus and juvenile fish in Doon Upper, a reverse migration of Daphnia galeata was observed as a strategy allowing them to avoid both types of predators. However, in September, when M. fuliginosus lived in a 24 h refugium below the oxycline as a response to increasing predation risk posed by YOY fish penetrated the upper strata of water during day and night, reverse migrations of D. galeata were not clear. In Doon Lower, normal migration was observed as an advantageous behavioural response against visual predators (fish), in both large and small Cladocera species: D. galeata, Diaphanosoma branchyurum and Bosmina sp. Thus, our results indicate dissimilar migration patterns of D. galeata depending on the presence of one (Doon Lower) or two predators with different predation behaviour (Doon Upper).

“…Phantom midge larvae can rest in anoxic mud during the day and move into normoxic water at night to feed on zooplankton (Englische et al 1982). In our study, Mochlonyx stayed below the oxycline both day and night in September (Fig.…”

“…In some freshwater invertebrates, e.g. larvae of the midge Chaoborus crystallinus (Englisch et al, 1982) and the leech Wienhausen, 1981) it is presumed that the glycolytic pathway, up to phosphoenolpyruvate (PEP), and the reverse citric acid cycle reactions resulting in the formation of succinate, are linked by the action of PEP carboxykinase. We have investigated whether this pathway is also operative in A. cygnea.…”

Abstract--1. After 6 days of anoxia A. cygnea had produced 1.0 pmole succinate, 2.7 pmole propionate and 1.7/~mole acetate/g of total soft tissue (wet). In addition, 0.35 #mole glutamate had disappeared. No other changes were detectable.2. Concentrations of anaerobic end products and of amino acids differed from organ to organ. Large portions of all end products produced were present in the fluids within the animal.3. Acetate and propionate were also excreted into the surrounding water. 4. In all tissues examined the activity ratio of pyruvate kinase and phosphoenolpyruvate carboxykinase was high 5. The [PEP]0. 5 of pyruvate kinase was relatively low (0.04-0.05 mM at pH 7.5), and the enzyme is not strongly inhibited at decreased pH or in the presence of alanine.6. Anaerobiosis influences this enzyme by decreasing the activity at low substrate concentration.

“…Studies of insects that specialize on habitats low in oxygen such as eutrophic pools or water-logged soil have demonstrated that insects can extensively utilize anaerobic metabolism (Hoback et al, 2000;Kölsch et al, 2002). For larvae, chironomid larvae inhabiting hypoxic water are known to anaerobically convert glycogen to ethanol and acetate (Redecker and Zebe, 1988), the larval midge Chaorobus crystallinus anaerobically converts malate to succinate during anoxia (Englisch et al, 1982), the soil-living dipteran Callitroga macellaria larva anaerobically converts glycogen and amino acids to lactate, alanine and polyols (Gäde, 1985), and larval tiger beetles that experience flooding anaerobically produce lactate and alanine (Hoback et al, 2000). For adults, Drosophila are known to accumulate lactate, alanine and acetate (Feala et al, 2007), and anoxic locusts, honey bees, flies and beetles have been shown to accumulate lactate, alanine, glycerol, glycerol 3-phosphate and succinate (reviewed by Gäde, 1985;Wegener, 1987).…”

Developmental changes in hypoxic exposure and responses to anoxia in Drosophila melanogaster

Holometabolous insects undergo dramatic morphological and physiological changes during ontogeny. In particular, the larvae of many holometabolous insects are specialized to feed in soil, water or dung, inside plant structures, or inside other organisms as parasites where they may commonly experience hypoxia or anoxia. In contrast, holometabolous adults usually are winged and live with access to air. Here, we show that larval Drosophila melanogaster experience severe hypoxia in their normal laboratory environments; third instar larvae feed by tunneling into a medium without usable oxygen. Larvae move strongly in anoxia for many minutes, while adults (like most other adult insects) are quickly paralyzed. Adults survive anoxia nearly an order of magnitude longer than larvae (LT50: 8.3 versus 1 h). Plausibly, the paralysis of adults is a programmed response to reduce ATP need and enhance survival. In support of that hypothesis, larvae produce lactate at 3× greater rates than adults in anoxia. However, when immobile in anoxia, larvae and adults are similarly able to decrease their metabolic rate, to about 3% of normoxic conditions. These data suggest that Drosophila larvae and adults have been differentially selected for behavioral and metabolic responses to anoxia, with larvae exhibiting vigorous escape behavior likely enabling release from viscous anoxic media to predictably normoxic air, while the paralysis behavior of adults maximizes their chances of surviving flooding events of unpredictable duration. Developmental remodeling of behavioral and metabolic strategies to hypoxia/anoxia is a previously unrecognized major attribute of holometabolism.
