Sustainability in agriculture has two dimensions: a. Natural Resource Sustainability b. Socioeconomic Sustainability Natural Resource Sustainability is based on the stability of the ecology of agricultural ecosystems based on interactions between soil, water and biodiversity. This Sustainability measures the wealth of' nature's economy' and the foundation of all other economies. Nature's econom...

Melatonin seems to be an almost ubiquitous substance, which has been detected not only in metazoans, but also in all major non-metazoan taxa investigated, including bacteria, dinoflagellates, euglenoids, trypanosomids, fungi, rhodophyceans, pheophyceans, chlorophyceans and angiosperms. Despite its vast abundance, little is known to date about its functions. Its presence is not necessarily assoc...

La transe cognitive auto-induite est un état de conscience modifiée volontaire, tout comme l’hypnose et la méditation. Elle se caractérise par une l’environnement, absorption intense dans l’expérience immersive, imagerie interne très développée, ainsi qu’une modification des processus somato-sensoriels. Cette technique hérit&#...

Sexual behaviour in most of the noctuid Lepidoptera follows a diel periodicity and is limited to a precise period of either the day or the night. The periodicity and the maturation periods are specifi c as well as the onset of oviposition behaviour. The knowledge of these traits of biology is an essential prerequisite for all the studies in chemical ecology. The periodicity of adult emergence, ...

Circadian rhythms are endogenous oscillations that occur with a period close to 24 h in nearly all living organisms. These rhythms originate from the negative autoregulation of gene expression. Deterministic models based on such genetic regulatory processes account for the occurrence of circadian rhythms in constant environmental conditions (e.g., constant darkness), for entrainment of these rh...
