The most misunderstood force driving health and disease The story of the invention and use of electricity has often been told before, but never from an environmental point of view. The assumption of safety, and the conviction that electricity has nothing to do with life, are by now so entrenched in the human psyche that new research, and testimony by those who are being injured, are not enough to change the course that society has set. Two increasingly isolated worlds--that inhabited by the majority, who embrace new electrical technology without question, and that inhabited by a growing minority, who are fighting for survival in an electrically polluted environment--no longer even speak the same language. In The Invisible Rainbow, Arthur Firstenberg bridges the two worlds. In a story that is rigorously scientific yet easy to read, he provides a surprising answer to the question, "How can electricity be suddenly harmful today when it was safe for centuries?"
Every hundred years, as the story goes, two angels wonder out loud whether the bees are still swarming. For as long as the bees are swarming, the angels are reassured, the world holds together. Still, the tale suggests, the angels live in anxious anticipation of the End. Local beekeepers in Bosnia and Herzegovina retell the old tale with growing unease, as their honeybees weather the ground effects of climate change. Beekeeping in the End Times relates extreme weather events and quieter disasters that have been altering honey ecologies across Bosnia and Herzegovina since 2014. While world-wide endangerment of pollinators, and bees in particular, has been the subject of much global concern, e...
The book contemplates different ways of approaching the study of vegetation as well as the type of indices to be used. However, all the works pursue the same objective: to know and interpret nature from different points of view, either through knowledge of nature in situ or the use of technology and mapping using satellite images. Chapters analyze the ecological parameters that affect vegetation, the species that make up plant communities, and the influence of humans on vegetation.
Honey bees are social insects; they live together in large, well-organized family groups comprising three castes: queen (fertile female), workers (sterile females) and drones (males). During honey flow season, there is a considerable increase in the foraging activity of the workers and in the rate of egg laying by the queen. Sex determination in honey bees involves a multi-allelic locus, such that homozygotes develop as males and heterozygotes as females, whereas diet quality influences the caste determination in honey bees. Like all living organisms, honey bees can be infested with diseases and pests. Some of these are more deleterious to bee colonies than others, but it is important for th...
