Impact of changes in climatic variables on wild and cultivated mushroom in Rivers State, Nigeria
Résumé
Mushroom enjoyed as a local culinary delicacy in most parts of Nigeria is fast disappearing from our meals. The bulk of the edible mushrooms consumed in Nigeria are collected from the wild. Several wild mushroom species have disappeared from the Nigerian forests owing to deforestation and climate change. This study surveyed the impact of temperature and rainfall on the fruiting bodies of wild and cultivated species of Pleurotus ostreatus, Pleurotus tuberregium and Lentinius subnudus. It was observed that the wild mushroom had longer fruiting time and their fruiting bodies were smaller in weight compared to those cultivated. Given the numerous benefits of mushroom in health and nutrition, and the abundance of agro-waste from farming activities across Nigeria, a case is made for more cultivation of mushroom among rural dwellers towards reduction of the contribution to greenhouse gasses from burning agro-waste, and as a means of poverty reduction to forestall the use of firewood for cooking.
