Abstract

A complete guide on seed production and distribution in tropical regions: technical aspects and organisation of seed production, basic principles for plant improvement and seed biology, management of operations relating to seed production, harvesting and post-harvest conditioning. It also deals with rules for placing on the market of seed and the management of seed breeding companies.

Abstract

Tropical forage crops used to feed the livestock are of crucial important in the sustainable development of hot regions. The first part of this work is intended to guide the choice of forage plants and their crops (diversity of forage plants and their uses based on environments and livestock systems). The second focuses on the growing and management of forage crops (production techniques from planting to harvesting the crops). The challenges of woody forage, production of forage seed and the economics of forage production are also addressed. A CD-ROM presents case studies, illustrations and sheets for each plant.

Abstract

The honey bee waggle dance communication is a complex, unique, at times controversial, and ultimately fascinating behavior. In an elaborate figure-of-eight movement, a returning forager conveys the distance and direction from the hive to resources, usually the nectar and pollen that is their food, and it remains one of the most sophisticated, known forms of non-human communication. Not surprisingly, since its discovery more than 60 years ago by Karl von Frisch, the dance has been subject to investigations that span from basic biology through human culture and neurophysiology to landscape ecology. Here we collate recent advances in our understanding of the dance.
