Egg predators improve the hatching success of salamander eggs [PDF]

Ecology and Evolution, 2023
A common challenge that oviparous animals face is securing survivorship during the vulnerable embryonic stage. One of the parental investment strategies to improve survivorship is providing physical structures to protect the embryos. In amphibians, there

High Early Embryo Mortality and Low Hatching Success Observed in Aldabra Giant Tortoise Populations [PDF]

Ecology and Evolution
Turtles and tortoises are highly threatened yet understudied, particularly regarding reproductive traits and early life stages. In long‐lived species, reliance on adult census data can mask reproductive failure for decades before population declines ...

Hatching Success of Olive Ridley Sea Turtles in Semi‐Natural Nests: A Pilot Assessment of Microclimate Conditions at Batu Hiu Beach [PDF]

Ecology and Evolution
Olive ridley sea turtles (Lepidochelys olivacea) continue to experience population pressures across much of their global range, underscoring the need to understand how incubation environments influence reproductive outcomes in conservation settings. Semi‐

Temperature and salinity as key drivers of eggs hatching success in sibling species of the Contracaecum rudolphii (s.l.) complex from European waters [PDF]

Parasitology
Egg hatching is a critical stage in the life cycle of parasitic nematodes and is strongly influenced by abiotic factors. This study investigates, under in vitro condition, the effects of temperature (5 °C, 10 °C, 20 °C, 30 °C) and salinity (0–70 psu) on ...

Effects of controlled artificial incubation on hatching success, morphometric traits, and early physiological indicators in olive ridley sea turtles (Lepidochelys olivacea) from Banyuwangi coast, Indonesia [PDF]

Veterinary World
Background and Aim: Olive ridley sea turtles, Lepidochelys olivacea, are globally threatened marine reptiles whose reproductive success is strongly influenced by environmental conditions at their nests.

Will a changing climate affect hatching success in cavity-nesting birds: A case study with Eastern Bluebirds ()? [PDF]

Science Progress
A significant body of evidence indicates that climate change is influencing many aspects of avian ecology. Yet, how climate change is affecting, and is expected to influence some aspects of the breeding ecology of cavity-nesting birds remains uncertain ...

Mitigating the impact of microbial pressure on great (Parus major) and blue (Cyanistes caeruleus) tit hatching success through maternal immune investment. [PDF]

PLoS ONE, 2018
The hatching success of a bird's egg is one of the key determinants of avian reproductive success, which may be compromised by microbial infections causing embryonic death. During incubation, outer eggshell bacterial communities pose a constant threat of

Embryo Development and Effects of Temperature, Salinity, and Light Intensity on Egg Hatching of Calanoid Copepod Bestiolina amoyensis (Calanoida: Paracalanidae)

Frontiers in Marine Science, 2022
Bestiolina amoyensis distributes in subtropical inshore waters across the Pacific Ocean, with a relatively long reproductive lifespan and high intrinsic population increase rate compared with other small paracalanid species, which makes it a good ...

Long-term monitoring data reveal effects of age, population density, and environmental aspects on hatching success of Common Cranes (Grus grus)

Avian Research, 2022
Facing climate and land use change, a species’ ability to successfully adapt to changing environments is crucial for its survival. Extensive drainage and intensification of agriculture and forestry set wetlands and associated species at risk of ...

Maternal health status correlates with nest success of leatherback sea turtles (Dermochelys coriacea) from Florida. [PDF]

PLoS ONE, 2012
Of the seven sea turtle species, the critically endangered leatherback sea turtle (Dermochelys coriacea) exhibits the lowest and most variable nest success (i.e., hatching success and emergence success) for reasons that remain largely unknown.
