TL;DR: The effect of soil treatment with pesticides on arylsulphataseactivity fluctuated between promotion and inhibition, but inhibition was predominant, suggesting a direct role of alkaline soil pH in increasing resistance of alkali phosphatase to pesticides.
Abstract: The effect of soil treatment with brominal (a herbicide) and theinsecticide selecron (the equivalent field rates and five-fold) on population counts of bacteria, actinomycetes and celluloyticfungi in soil was tested throughout 10 weeks incubation at28 °C. Also, tested their effect on four soil enzymes:cellulase, acid phosphatase, alkaline phosphatase andarylsulphatase. Bacterial and actinomycetes populations in soiltreated with the two pesticides were promoted at fieldapplication rates and inhibited at higher levels. The twopesticides significantly decreased the total number ofcellulolytic fungi and most fungal species after most incubationperiods either by one or the two used levels but the effect ofselecron was more pronounced.Cellulase activity in soil treated with brominal and selecronwas inhibited after most incubation periods. The effect of soiltreatment with the two pesticides on acid phosphatase waspromotive at field application rates after some incubationperiods but the enzyme activity was delayed at the higherapplication doses. Alkaline phosphatase activity in treated soilwas accelerated with both pesticides even at the higherapplication rates, suggesting a direct role of alkaline soil pHin increasing resistance of alkaline phosphatase to pesticides.The effect of soil treatment with pesticides on arylsulphataseactivity fluctuated between promotion and inhibition, butinhibition was predominant.

TL;DR: It is unlikely that maternal androgens are a key factor in the avian sex determination mechanism, as testosterone levels in chicken eggs do not change with incubation period.

TL;DR: The results suggest that experimental incubation temperatures of 20◦C or above should be used in the application of the methodology ISO 16072:2002, and that pre-incubation temperature did not affect the soil basal respiration rate, when following the standard recommendations.

TL;DR: The results showed that genetic strain and parent flock age influence daily embryonic metabolism, especially during the early and latter days of incubation, as well as the relationship between embryonic metabolic heat production and mortality during incubation.
