Pinpointing baobab (Adansonia digitata [Linn. 1759]) population hotspots in the semi‐arid areas of Tanzania
(John Wiley & Sons, 2019-11-15)The impact of unsustainable land‐use conversions, changes in climate and anthropogenic activities on abundance and distribution of baobab populations was assessed in semi‐arid regions of Tanzania. Baobabs were sampled in ... -
Plague and climate: scales matter.
(PLoS Pathogens, 2011-09-01)Plague is enzootic in wildlife populations of small mammals in central and eastern Asia, Africa, South and North America, and has been recognized recently as a reemerging threat to humans. Its causative agent Yersinia ... -
Plant competition as an ecosystem-based management tool for suppressing Parthenium hysterophorus in rangelands
(Elsevier, 2021-01-29)Abstract The exotic invasive plant pathenium hystephorus is invading rangelands in Africa while causing negative effects on the biodiversity, environment, economy, and human and animal health because eco-friendly control ... -
Plant Growth Promoting Rhizobacterial Biofertilizers for Sustainable Crop Production: The Past, Present, and Future
(Preprints, 2020-09-26)The world’s population is increasing and so are agricultural activities to match the growing demand for food. Conventional agricultural practices generally employ artificial fertilizers to increase crop yields, but these ... -
Plant growth-promoting rhizobacterial biofertilizers for crop production: The past, present, and future
(Frontiers, 2022-09-16)Recent decades have witnessed increased agricultural production to match the global demand for food fueled by population increase. Conventional agricultural practices are heavily reliant on artificial fertilizers that ... -
Plant-Rich Field Margins Influence Natural Predators of Aphids More Than Intercropping in Common Bean
(MDPI, 2022-06-23)Field margins support important ecosystem services including natural pest regulation. We investigated the influence of field margins on the spatial and temporal distribution of natural enemies (NEs) of bean pests in ... -
Plasmid characterization in bacterial isolates of public health relevance in a tertiary healthcare facility in Kilimanjaro region, Tanzania
(Elsevier, 2022-09)Objectives Plasmids are infectious double stranded DNA molecules that are found within bacteria. Horizontal gene transfer promotes successful spread of different types of plasmids within or among bacteria species, making ... -
