“…Local hypoxia is thought to be the proximate cue for most terrestrial eggs that hatch when flooded (DiMichele and Taylor 1980, Petranka et al 1982, Warkentin 2002. Hypoxia stimulates hatching in invertebrates (Gjullin et al 1941, Fallis and Snow 1983, Miller 1992, fishes (DiMichele andTaylor 1980, Latham andJust 1989), amphibians (Petranka et al 1982, Bradford andSeymour 1988), and at least one reptile (Losos et al 2003). Thus, a hatching response to hypoxia is either a very ancient trait or has evolved Notes: ML a is the maximum likelihood estimate of evolutionary constraint (Martins 2004).…”

Abstract. Adaptive plasticity at switch points in complex life cycles (e.g., hatching, metamorphosis) is well known, but the evolutionary history of such plasticity is not. Particularly unclear is how a single plastic response (e.g., shifts in hatching timing) evolves to respond to different threats and cues (e.g., abiotic and biotic). We conducted a comparative phylogenetic study of hatching plasticity in a group of frogs with arboreal embryos to determine when risk-accelerated hatching evolved in the clade, whether responses to two common egg-stage risks (snake predation and flooding) evolved independently, and whether the overall capacity for hatching plasticity was evolutionarily more conservative than responses to specific cues. Red-eyed treefrogs (Agalychnis callidryas) hatch early to escape from several egg-stage risks but otherwise hatch later, improving larval survival with predators. We reconstructed a phylogeny for Agalychnis and related genera based on three mitochondrial and four nuclear genes. We quantified onset of hatching competence, spontaneous hatching timing, responses to egg-stage risks, and costs of premature hatching in Agalychnis and Pachymedusa. We also assessed hatching plasticity in a basal phyllomedusine, Cruziohyla calcarifer. The capacity to hatch ;30% before the spontaneous hatching age appears ancestral for phyllomedusines, with little change over ;34-50 million years among the species examined. A strong hatching response to flooding, with no mortality of hatching-competent eggs, is similarly ancient and conserved. Premature hatchlings of Agalychnis and Pachymedusa are more vulnerable to fish predation than are full-term hatchlings, indicating a conserved risk trade-off across hatching that would make plasticity advantageous. In contrast, the hatching response to snake attack has undergone major changes at least twice in the Agalychnis-Pachymedusa clade, with two species showing substantially lower escape success than the others. Responses to different threats have thus evolved independently. The capacity for switch point plasticity may be evolutionarily more stable than the response to individual stage-specific threats.

“…cantans as a woodland mosquito (Rees & Snow, 1996). Eggs are generally laid in dried‐up hollows and ditches or above the level of standing water during the summer months, which later become flooded by autumn and winter rains, with eggs hatching from December onwards in response to deoxygenation of pools by bacterial growth (Fallis & Snow, 1983). Ochlerotatus punctor often breeds in more or less acid waters, in areas of sandy and gravelly soils, such as those lined with dead leaves or Sphagnum or in open heath or woodland where birch and pine predominate (Marshall, 1938).…”

“…This has been observed in previous experiments and may be a form of negative feedback. Bacterial populations are responsible for the drop in the oxygen concentration in the hatch medium, which acts as the actual hatch stimulus (Gjullin et al 1941, Judson 1960, Fallis and Snow 1983. As more larvae hatch, they feed on the bacteria, limiting any further drop in oxygen concentration in the hatch medium, which inhibits further hatching during the 24-h period that eggs are submerged (Livdahl and Edgerly 1987).…”

Eggs of container-breeding mosquitoes are able to withstand drought conditions as an egg and hatch when submerged. Frequent rainfall can be simulated by frequent submersion, and drought conditions can be simulated by infrequent submersion. We examined the hatch response of Aedes albopictus (Skuse) eggs to simulated drought conditions. Ae. albopictus eggs from a strain originating outside Kobe, Japan, were subjected to one of three treatments; high-frequency hatch stimulation consisting of submerging the eggs in a nutrient broth mixture every 3 d, low-frequency hatch stimulation consisting of submerging the eggs every 7 d, and delayed high-frequency hatch stimulation. Eggs that were subjected to lower-frequency stimulation showed a significant decrease in hatch delay, which was the opposite of the predicted response. This decrease in hatch delay may be an example of hatch plasticity in response to drought conditions. This response could not be explained as a result of the difference in the ages of the eggs on any given stimulus. A decreased hatch delay response to potential drought conditions combined with rapid larval development may enable Ae. albopictus, whose eggs are not as desiccation resistant as some other container-breeding mosquitoes, to survive extended drought.
