The dormant eggs hatch during favourable environmental conditions and only a fraction of the resting stages hatch per each inundation (Brock etLarge branchiopods are among the most spectacular representatives of temporary pond fauna, suitable as flagship species for the conservation of this habitat type. Romania hasBecause of the vulnerability of branchiopods to predation, branchiopods are at risk whether precipitation increases or decreases with global climate change. The reduced precipitation (especially in summer) during the late '80's depleted the sediment cyst bank, reducing the potential size of future hatching populations by some unknown amount.Summary The Branchiopods are a diverse and ancient class of crustaceans occurring in freshwaters, marine and (some genera) in hyper-saline environments. They include the Cladocera (or water fleas), fairy and brine shrimps, tadpole shrimps and clam shrimps. Morphologically heterogeneous, they are united by the structure of thoracic limbs which have flattened structures associatedAnnotated classification. The following classification is based largely on that given in Synopsis and Classification of Living Organisms (1982) but has been modified to take account of advances made since that date.
