The European Zoological Journal, 2020 The causes and consequences of variation in the incubation regimes of oviparous animals remain unclear, despite having important fitness consequences. Avian incubation regimes can be shortened by parents initiating incubation prior to clutch completion ...

Effects of on-farm hatching on hatching success and first-week chick performance of local and commercial broiler genotypes. [PDF]
Arch Anim BreedThis study was conducted to compare conventional hatchery-hatching and on-farm-hatching systems in terms of hatching success and first-week chick performance for commercial Cobb 500, Ross 308, and local Anadolu-T genotypes. Eggs in both the conventional and on-farm-hatching groups were subjected to standard hatchery procedures ...

Isolation by sugar flotation has no direct effect on the hatching success of zooplankton resting eggs [PDF]
Journal of Limnology, 2016 Zooplankton in temporary waters produces resting stages to survive recurrent dry periods. Branchiopod crustaceans (i.e., cladocerans, large branchiopods) overcome these periods in the form of resting eggs buried in the sediment.

Behavioral thermoregulation by reptile embryos promotes hatching success and synchronization. [PDF]
Commun Biol, 2023 AbstractReptile embryos can move inside eggs to seek optimal thermal conditions, falsifying the traditional assumption that embryos are simply passive occupants within their eggs. However, the adaptive significance of this thermoregulatory behavior remains a contentious topic.

Copepod hatching success in marine ecosystems with high diatom concentrations
Nature, 2002 Diatoms dominate spring bloom phytoplankton assemblages in temperate waters and coastal upwelling regions of the global ocean. Copepods usually dominate the zooplankton in these regions and are the prey of many larval fish species. Recent laboratory studies suggest that diatoms may have a deleterious effect on the success of copepod egg hatching. These

Light Sandy Beaches Favour Hatching Success and Best Hatchling Phenotype of Loggerhead Turtles
Frontiers in Ecology and Evolution, 2022 We conducted a 5-year field (2017–2021) and laboratory study of the relationship between type of substrate and hatching success, embryonic development, and the quality of hatchlings in loggerhead turtle nests.

Embryonic death is linked to maternal identity in the leatherback turtle (Dermochelys coriacea). [PDF]
PLoS ONE, 2011 Leatherback turtles have an average global hatching success rate of ~50%, lower than other marine turtle species. Embryonic death has been linked to environmental factors such as precipitation and temperature, although, there is still a lot of ...

Avocetta, 2021 In 2008, we investigated the relationships between the hatching success of the Little Grebe Tachybaptus ruficollis with egg laying onset, nest diameter, as a proxy of nest size, and egg weight, as a proxy of egg size, in an artificial wetland in ...

Temperature–Induced Hatch Failure and Nauplii Malformation in Antarctic Krill
Frontiers in Marine Science, 2020 Antarctic krill inhabit areas of the Southern Ocean that can exceed 4.0°C, yet they preferentially inhabit regions with temperatures of −1.5 to ≤1.5°C.
