As we all feel the impact of and anticipate containment COVID-19, Systems Biology in Reproductive Medicine (SBiRM) offers a unique perspective. SBiRM covers combination male fem...

introduction: cloning an individual by transferring somatic nuclei into enucleated recipient oocytes has already been well established. this technology also offers new opportunities to restore threatened species with interspecies somatic cell nuclear transfer (scnt). however, few mammalian species have been studied for their reproductive biology whereas huge differences have been observed betwe...

In studies done a decade apart, we provide evidence of a recent shift toward a slower progression to sexual maturity as well as reduced egg production, especially among young, small female red snapper, in the Gulf of Mexico (Gulf). Slower maturation rates (among fish ≤6 years old), lower GSI values and decreased spawning frequency were observed, and were especially pronounced in the northwester...

In the second half of the nineteenth century, pioneering discoveries of rich assemblages of fossil plants from the Cretaceous resulted in considerable interest in the first appearance of angiosperms in the geological record. Darwin's famous comment, which labelled the 'rapid development' of angiosperms an 'abominable mystery', dates from this time. Darwin and his contemporaries were puzzled by ...

A given man's phenotype embodies cues of his ancestral ability to effectively defend himself and his kin from harm, to survive adverse conditions, and to acquire status and mating opportunities. In this review, we explore the hypothesis that a man's phenotype also embodies cues to fertility or the probability that an ejaculate will fertilize ova. Female mate choice depends on the ability to dis...

Soon after the Great East Japan Earthquake and the subsequent accident at the Fukushima Daiichi nuclear power plant, we studied the reproductive biology of freshwater teleost bluegill (Lepomis macrochirus) in a pond in the city of Iwaki, Fukushima Prefecture, about 50 km south of the nuclear power plant. The breeding period of the bluegill was abbreviated and the frequency of spawning decreased...

This chapter deals with the biology of rice (Oryza sativa), a revision original 1999 publication. It contains information for use during risk/safety regulatory assessment genetically engineered varieties intended to be grown in environment (biosafety). includes elements taxonomy, centres origin, cultivation, reproductive biology, genetics, hybridisation and introgression, as well ecology. Annex...
