“…Significant negative effects of toxicants on hatching of Daphnia dormant eggs have been reported previously in a few studies (Angeler et al 2005;Raikow et al 2006Raikow et al , 2007. Our findings are in agreement with the results of Raikow et al (2006Raikow et al ( , 2007, who observed that the biocide SeaKlean had significant negative effects on hatching of D. mendotae dormant eggs, but with a ten times lower sensitivity compared to neonate mortality (Song et al 2011).…”

“…The biocides sodium hypochloride and menadione (SeaKleen) affected hatching success of D. mendotae dormant eggs, but effect levels were higher compared to other D. mendotae life stages (Raikow et al 2006(Raikow et al , 2007. Angeler et al (2005) tested for effects of fire retardant treatments and found a significant negative effect of Fire Trol 943 on emergence of D. curvirostris dormant eggs from wetland sediments. For rotifers, Marcial et al (2005) found that diazinon, fenitrothion, methoprene and isoprothiolane affected hatching of Brachionus plicatilis dormant eggs at concentrations 2-40 times lower than concentrations affecting population growth, mixis and fertilization endpoints.…”

Pesticide exposure impacts not only hatching of dormant eggs, but also hatchling survival and performance in the water flea Daphnia magna

Laboratory ecotoxicity tests and biomonitoring in aquatic systems are currently based on the active component of invertebrate communities. Even though dormant egg banks are crucial for the long term survival and community dynamics of many aquatic organisms, the effects of anthropogenic activities on dormant egg bank dynamics have rarely been studied. In this study we investigated the effects of two pesticides with a different mode of action (carbaryl and fenoxycarb) on hatching of Daphnia magna dormant eggs (ephippia) as well as on survival, growth and reproduction of the hatched neonates. Dormant eggs were exposed to the pesticides simultaneously to incubation under conditions that induce hatching (long daylight and 20°C). Carbaryl had no negative effects on embryonic development or hatching rate up to concentrations almost 1,000 times the median effect concentration (EC 50 ) of neonate survival in acute tests. Fenoxycarb, however, had a significant dose-related effect by delaying or completely stopping the hatching process and caused severe abnormalities in developing individuals. Both pesticides had significant negative effects on survival and reproduction of the hatchlings. These results indicate that, in addition to inducing mortality of active individuals, pesticides can affect zooplankton communities by altering hatching dynamics and life history traits of hatched individuals. We briefly discuss how such pollution induced changes in the benthic-pelagic coupling could translate into transgenerational effects impacting ecological and evolutionary dynamics.

“…Similarly, Angeler et al . () revealed that higher levels of fire‐retardant used by fire managers to control wildfires resulted in depressed hatching successes of Daphnia curvirostris , indicating the potential dual effects of fire. On the contrary, de Szalay and Resh (), focussing on invertebrates important to waterfowl diet, reported slightly higher invertebrate densities in burned treatment areas than in un‐manipulated control areas.…”

The negative impacts of fire on the resurrection ecology of invertebrates from temporary wetlands in Cape Flats Sand Fynbos in the Western Cape, South Africa

et al. 2019

Fire is an important environmental disturbance in Mediterranean-climate regions; however, its intensity and frequency are predicted to increase under climate change scenarios with unknown implications for ecosystems in these regions. Temporary wetlands, with their periodic wet and dry phases, are considered one of the most productive systems in the world and their invertebrate communities form a crucial diet component for higher trophic levels. The effect of fire on the hatching success of invertebrate propagules from temporary wetlands in the Cape Flats Sand Fynbos (Cape Town, South Africa) was investigated. Homogenised soil samples from these wetlands were either experimentally subjected to vegetation fires (treatment samples) or were left as is (control samples). The results revealed that fire had a significant negative impact on invertebrate hatching success, as revealed by analyses of the different diversity measures (e.g. taxon richness, Shannon diversity and Pielou's evenness) and community composition. Proper management of fire, especially in the Mediterraneanclimate regions, which replicates the natural fire intervals typical of the area (10-15 years) and avoids unregulated or accidental fires, is essential to ensuring future protection of these critical biodiversity hotspots created by the temporary wetlands.
