“…Although the adaptations shown by individual species are varied, members of a same major taxonomic groups tend to have similar stages in their life cycles that resist drying out. Thus, mayflies, lestid odonates, and mosquitoes largely survive drought as eggs (Lehmkul 1973, Wood et al 1979, many beetles and hemipterans survive as adults (Macan 1939), and stoneflies survive by diapausing as early instar nymphs (Harper & Hynes 1970). Chironomids may diapause as larvae or eggs (Thienemann 1954).…”

“…A somewhat surprising occurrence in the Pant-y-Llyn pond was the stonefly Nemoura cinerea, as the Plecoptera are rarely found in standing waters, and especially not temporary pondsÐalthough, in North America, species of Capniidae and Taeniopterygidae are known from temporary streams where they survive the drought as diapausing nymphs (Harper and Hynes, 1970). Nemoura cinerea is very abundant and widespread in Britain, including in slow-flowing and standing waters (Hynes, 1977).…”

1. Temporary waters are bodies of water that experience a recurrent dry phase of varying length that is sometimes predictable in its onset and duration. The maximum number of temporary and permanent ponds in England and Wales in 1880 is estimated to be >1 million. A 1920s survey showed lowest densities in mountainous areas (0.12 km−2) and highest densities in ancient woodland and ancient agriculture areas (115 km−2). 2. The most important physical and chemical influences on the biota of temporary ponds are the length of the aquatic phase, pattern of disappearance of the water, and whether the latter is predictable or unpredictable. Biological influences include the degree of inter/intraspecific competition and predation, and the seasonal influx of aerial colonizers. 3. Temporary ponds from Britain, northeastern North America and northwestern Australia are compared and, despite large differences in climate and zoogeography, considerable similarity is evident amongst their faunas. Snails, microcrustaceans, aquatic mites, springtails, odonates, chironomids, and a high diversity of Hemiptera and Coleoptera are characteristic of these habitats. British ponds share at least 33 genera and three species with their North American counterparts. The three main evolved strategies by which invertebrates survive in temporary ponds are physiological tolerance, life history modification, and migration. 4. The cyclical nature of the temporary pond environment creates a habitat that is distinctive enough to support species either not found in any other habitat type or that attain their greatest populations in these ponds. 5. Agricultural drainage and pond ‘improvement’ schemes are seen as distinct threats to the survival of temporary ponds and should be reviewed in the context that these water bodies are not ‘wasted’ areas of land but natural features of the environment. It is recommended that the management of wetlands in Britain should be directed towards maintaining a high diversity of natural water bodies, including a variety of temporary pond types. © 1997 John Wiley & Sons, Ltd.

“…In addition to desiccation-resistant eggs, desiccation-resistant larvae and pupae are known among aquatic insects (Harper & Hynes 1970;Imhof & Harrison 1981;Sommerhauser et al 1997;Scarsbrook 2000;Winterbourn 2004). Insects may also survive the dry period as terrestrial adults if adults are sufficiently long-lived or are able to diapause (Bouvet 1977;Sommerhauser et al 1997;Williams 2006).…”

Life histories and life history strategies of invertebrates inhabiting intermittent streams in Hawke's Bay, New Zealand

Intermittent streams are predicted to harbour macroinvertebrate taxa with particular life history traits that allow them to complete development in a limited time and survive periods without water. Three intermittent headwater streams in Hawke's Bay, New Zealand, had more taxa with very small body size, plurivoltine life cycles, low dissemination potential, long-lived adults and asexual reproduction than three nearby perennial streams. We traced the population size structure and adult flight periods of six aquatic insect taxa, and the population size structure of an aquatic snail, in three intermittent streams to provide basic information on larval growth rates and infer whether they use particular life history stages to survive summer drought. The insect taxa appeared to over-summer primarily as eggs, whereas the snail Potamopyrgus antipodarum oversummered at various stages of maturity. Final instar larvae and adults of most insect taxa appeared well ahead of stream drying, suggesting they can survive early-onset drought. However, late-onset drought would allow more larvae to complete development.
