Classic marine ecological paradigms view kelp forests as inherently temperate-boreal phenomena replaced by coral reefs in tropical waters. These paradigms hinge on the notion that tropical surface waters are too warm and nutrient-depleted to support kelp productivity and survival. We present a synthetic oceanographic and ecophysiological model that accurately identifies all known kelp populatio...

Nigerseed as an Oilseed Crop Nigerseed (Guizotia abyssinica, Asteraceae) is native to Africa, from Ethiopia to Malawi, and was probably domesticated in Ethiopia. Early introduction of nigerseed to India was followed by the development of sizeable commercial production (Simmonds 1976) and neighboring Pakistan also cultivates the crop (Weiss 2000). Nigerseed is an important oil crop in Ethiopia a...

Barbados aloe (Aloe vera (L.) Burm. F.) has traditionally been used for healing in natural medicine. However, aloe is now attracting great interest in the global market due to its bioactive chemicals which are extracted from the leaves and used in industrial preparations for pharmaceutical, cosmetic, and food products. Aloe originated from tropical and sub-tropical Africa, but it is also now cu...

Ciguatera is a specific type of food poisoning associated with the ingestion of tropical fish, which, although normally safe for consumption, may at times contain high amounts of ciguatoxin, as well as other chemically related toxins. Widespread in tropical regions where coral reefs are present, ciguatera fish poisoning constitutes a major hindrance for local fishing industries, local economies...
