Kihansi spray wetlands under mitigation measures and its implication to the biodiversity of the resultant ecosystems

Originally, the Kihansi River Falls produced sprays that created microhabitat with high humidity and low temperatures. These microhabitats were the only habitats for Kihansi Spray Toad (KST) Nectophyrinoides asperginis, while adjacent forest supported other endemic species. However, in 1999 the Kihansi Hydropower Project diverted over 90% of the water from Kihansi River to the reservoir […]

Effect of explants, salts concentration medium and hormone treatments on Taxus baccata in vitro culture

Taxus baccata is an endangered forest tree species with low regeneration. The highest Callus induction (96.67%) was occurred on ½ MS medium which had one-fourth nitrogen (KNO3, NH4NO3) supplemented with glutamine, 1 mg/l 2,4-D and 1 mg/l Kin from stem. The maximum callus size (80.67 mm2) was obtained from leaf culture on ½ MS medium […]
