Carp eggs were exposed immediately after fertilization to Cu concentrations of 0.3 and 0,8 (xmol/L at water pH 7.6 or pH 6.3. Mortality, the incidence of spina! cord deformation, heart rate, tail movements, hatching success, and whole-body content of K, Na, Mg, Ca, and Cu were determined over time. Light microscopical preparations of eggs (48 h after fertilization) and larvae (168 h after ferti...

The present study revealed the toxic effect of silver nanoparticles (AgNPs) in Artemia nauplii and evaluated the mortality rate, hatching percentage, and genotoxic effect in Artemia nauplii/cysts. The AgNPs were commercially purchased and characterized using field emission scanning electron microscope with energy dispersive X-ray spectroscopy. Nanoparticles were spherical in nature and with siz...
The harlequin ladybird, Harmonia axyridis, is a valuable asset in integrated pest management (IPM); however, issues related to low-temperature storage and transportation have resulted low hatching rate, while the use of pesticides may lead non-target effects against this natural enemy during field application. Fluctuating thermal regimes (FTR) been shown be beneficial storage, type concentratio...
Survival rates of early life stages (eggs/hatchlings) in marine turtle populations critically influence adult recruitment rate and thus population persistence (Mazaris et al. 2005, 2006). Therefore, for conservation and management purposes, it is particularly important to understand how marine turtle hatching success (percentage of eggs that produce hatchlings) may be affected by human disturba...
