Ecological interactions, local people awareness and practices on rodent-borne diseases in Africa: A review
(Elservier, 2023-02)Several anthropogenic activities exposure humans to the risk of rodent-borne diseases. These activities are but not limited to logging, clearing land for crop cultivation, and consuming rodents. Rodents are a highly diverse ... -
The effect of temperature during cone and seed development on primary dormancy of Scots pine (Pinus sylvestris L.) seeds
(Springer, 2021)Scots pine (Pinus sylvestris L.) seeds have variable levels of primary dormancy which reflect within-species adaptation to local environments. The objective of this study was to use a thermal time approach to determine ... -
Effects of different silage preservatives on silage quality of pennesitum purpureum harvested at different harvesting periods.
(Scienceline Publishers, 2011)The study was conducted to determine the effects of preservatives on the chemical composition of elephant grass (P. purpureum Bana cv.) harvested from N-fertilized and unfertilized treatments at different periods (3, 6 and ... -
The Effects of Monthly Rainfall and Temperature on Flowering and Fruiting Intensities Vary within and among Selected Woody Species in Northwestern Ethiopia. Forests.
(MDPI, 2023-03-10)The phenological responses of plants to climatic variables are critical for conservation planning; however, it is less understood in an Afrotropical context. Here, we observed how flowering and fruiting phenophases of seven ... -
